- the gas phase passage and the liquid phase passage connecting the heat exchanger for equipment and the condenser are provided.
- this apparatus temperature control apparatus is equipped with the heating part which can heat a working fluid inside the heat exchanger for apparatuses.

- the apparatus temperature control apparatus 1 functions also as a warming-up apparatus which warms up the assembled battery 2.
- a power storage device in other words, a battery pack
- the assembled battery 2 self-heats when power is supplied while the vehicle is running.

Therefore, it is necessary to limit output and input so that self-heating is reduced. For this reason, in order to ensure the output and input of the assembled battery 2, a cooling device for maintaining the assembled battery 2 below a predetermined temperature is required.
- the battery temperature rises not only when the vehicle is running but also when parked.
- the assembled battery 2 is often arranged under the floor of a vehicle, under a trunk room, etc., and although the amount of heat per unit time given to the assembled battery 2 is small, the battery temperature gradually rises when left for a long time. If the assembled battery 2 is left in a high temperature state, the life of the assembled battery 2 is shortened.

- FIG. 1 an example of the height of the liquid level during warm-up is indicated by a one-dot chain line FL.
- the equipment heat exchanger 10 has a cylindrical upper tank 11, a cylindrical lower tank 12, and a flow path that connects the upper tank 11 and the lower tank 12. It is composed of a plurality of tubes 131. Instead of the plurality of tubes 131, the upper tank 11 and the lower tank 12 may be connected by a plurality of flow paths formed inside the plate-like member.
- Each component of the equipment heat exchanger 10 is formed of a metal having high thermal conductivity such as aluminum or copper.
- each structural member of the heat exchanger 10 for apparatuses can also be comprised with materials with high heat conductivity other than a metal.
- the part comprised by the some tube 131 or the plate-shaped member among the heat exchangers 10 for apparatuses shall be called the heat exchange part 13.

Flows to the side. Therefore, the liquid film of the working fluid formed on the side wall 137 in the tube 131 gradually increases from the upper side to the lower side. Therefore, since the liquid film of the working fluid is thin above the apparatus heat exchanger 10, the heating capacity of the battery cells 21 due to the latent heat of condensation of the working fluid is relatively large.
- the heating capacity of the battery cell 21 due to the latent heat of condensation of the working fluid becomes relatively small.
- the liquid level FL of the working fluid is high below the equipment heat exchanger 10, and the heating capacity of the battery cell 21 due to the latent heat of condensation of the working fluid is very small below the liquid level FL.

- the working fluid temperature sensor 102 detects the temperature of the working fluid circulating in the thermosiphon circuit of the device temperature control device 1. The higher the temperature of the heating unit 61 with respect to the temperature of the working fluid circulating in the thermosiphon circuit, the greater the heating capacity of the assembled battery 2 by the device temperature control device 1, and thus the temperature distribution of the assembled battery 2 becomes larger.
- the control device 5 detects the size of the temperature distribution of the assembled battery 2 based on the time during which the heating unit 61 is continuously operated.
- the time during which the heating unit 61 is continuously operated is the continuous energization on-time for the heating unit 61 detected by the heater energization time detection unit 111. The longer the time during which the heating unit 61 is operating continuously, the greater the temperature distribution of the assembled battery 2.
- control apparatus 5 can also detect the magnitude
- the time during which the heating unit 61 continuously stops operating is the continuous energization off time to the heating unit 61 detected by the heater energization time detection unit 111. The longer the time during which the heating unit 61 is continuously stopped, the smaller the temperature distribution of the assembled battery 2.

本開示は、対象機器の温度を調整する機器温調装置に関するものである。
This disclosure relates to a device temperature control device that adjusts the temperature of a target device.
従来、ループ型のサーモサイフォン方式により、対象機器の温度を調整する機器温調装置が知られている。
Conventionally, a device temperature control device that adjusts the temperature of a target device by a loop thermosyphon method is known.
特許文献1に記載の機器温調装置は、対象機器としての組電池と作動流体とを熱交換させる機器用熱交換器と、その機器用熱交換器より重力方向上側に配置された凝縮器と、機器用熱交換器と凝縮器とを接続する気相通路および液相通路を備えている。また、この機器温調装置は、機器用熱交換器の内側に、作動流体を加熱することの可能な加熱部を備えている。
The apparatus temperature control apparatus described in Patent Document 1 includes an apparatus heat exchanger that exchanges heat between an assembled battery as a target apparatus and a working fluid, and a condenser that is disposed above the apparatus heat exchanger in the direction of gravity. The gas phase passage and the liquid phase passage connecting the heat exchanger for equipment and the condenser are provided. Moreover, this apparatus temperature control apparatus is equipped with the heating part which can heat a working fluid inside the heat exchanger for apparatuses.
特許文献1に記載の機器温調装置は、組電池の冷却時に、機器用熱交換器の内側の作動流体が組電池から吸熱して蒸発し、気相通路を通って凝縮器に流入する。凝縮器で凝縮した液相の作動流体は、液相通路を通り機器用熱交換器に流入する。このように、機器温調装置は、作動流体の循環により組電池を冷却する構成となっている。
In the apparatus temperature control apparatus described in Patent Document 1, when the assembled battery is cooled, the working fluid inside the apparatus heat exchanger absorbs heat from the assembled battery and evaporates, and flows into the condenser through the gas phase passage. The liquid-phase working fluid condensed by the condenser flows into the equipment heat exchanger through the liquid-phase passage. Thus, the device temperature control device is configured to cool the assembled battery by circulating the working fluid.
また、特許文献1に記載の機器温調装置は、組電池の暖機時に、機器用熱交換器の内側に設けられた加熱部により作動流体を加熱する。加熱された作動流体は、機器用熱交換器の内側で気化した後、組電池に放熱することで、凝縮する。このように、機器温調装置は、機器用熱交換器の内側での作動流体の相変化により組電池を加熱する構成となっている。
Moreover, the apparatus temperature control apparatus of patent document 1 heats a working fluid with the heating part provided inside the heat exchanger for apparatuses at the time of warming up of an assembled battery. The heated working fluid condenses by vaporizing inside the equipment heat exchanger and then radiating heat to the assembled battery. Thus, the device temperature control device is configured to heat the assembled battery by the phase change of the working fluid inside the device heat exchanger.
しかしながら、特許文献1に記載の機器温調装置は、機器用熱交換器の内側に加熱部が設けられている構成である。そのため、組電池の暖機時に、機器用熱交換器の内側で加熱部の近傍の作動流体が局所的に気化し、加熱部から離れた場所の作動流体が加熱されない。したがって、この機器温調装置は、機器用熱交換器の内側で作動流体の温度のばらつきが大きくなり、組電池を均一に暖機することができない。その結果、組電池を構成する一部の電池セルが十分に暖機されず、組電池の入出力特性が低下し、組電池の劣化や破損に至るおそれがある。
However, the apparatus temperature control apparatus described in Patent Document 1 has a configuration in which a heating unit is provided inside the apparatus heat exchanger. Therefore, when the assembled battery is warmed up, the working fluid in the vicinity of the heating unit is locally vaporized inside the equipment heat exchanger, and the working fluid in a place away from the heating unit is not heated. Therefore, in this equipment temperature control device, the temperature variation of the working fluid becomes large inside the equipment heat exchanger, and the assembled battery cannot be warmed up uniformly. As a result, some battery cells constituting the assembled battery are not sufficiently warmed up, the input / output characteristics of the assembled battery are lowered, and the assembled battery may be deteriorated or damaged.
また、特許文献1に記載の機器温調装置は、組電池の暖機時に、作動流体の蒸発と凝縮が機器用熱交換器の内側のみで行われる。すなわち、機器用熱交換器の内側で、加熱部により加熱されて気化した作動流体が重力方向上側に流れ、組電池に放熱して凝縮した作動流体が重力方向下側に流れる。したがって、液相の作動流体と気相の作動流体とが対向して流れるので、機器用熱交換器の内側で作動流体の循環が阻害され、組電池の暖機効率が悪化することが懸念される。なお、上述した問題は、対象機器が組電池である場合に限らず、その他の機器についても同様に生じると考えられる。
Moreover, the apparatus temperature control apparatus described in Patent Document 1 evaporates and condenses the working fluid only inside the apparatus heat exchanger when the assembled battery is warmed up. That is, inside the equipment heat exchanger, the working fluid heated and vaporized by the heating unit flows to the upper side in the gravity direction, and the working fluid radiated and condensed to the assembled battery flows to the lower side in the gravity direction. Therefore, since the liquid-phase working fluid and the gas-phase working fluid flow opposite to each other, there is a concern that the circulation of the working fluid is hindered inside the equipment heat exchanger and the warm-up efficiency of the assembled battery is deteriorated. The Note that the above-described problem is not limited to the case where the target device is an assembled battery, but may also occur in other devices as well.

A heat exchanger for equipment configured to allow heat exchange between the target device and the working fluid so that the working fluid evaporates when the target device is cooled and the working fluid is condensed when the target device is warmed up;
An upper connection provided in the upper part of the gravitational direction of the heat exchanger for equipment, and through which the working fluid flows in or out;

これによれば、加熱部の作動が停止しているとき、凝縮器で凝縮した作動流体が自重により液相通路を通り下接続部から機器用熱交換器に流入する。その作動流体は、機器用熱交換器の内側で対象機器から吸熱して蒸発する。気相となった作動流体は上接続部から気相通路を通り凝縮器に流れる。その作動流体は、凝縮器で再び凝縮し、液相通路を通り機器用熱交換器に流入する。このような作動流体の循環により、機器温調装置は、対象機器の冷却を行うことが可能である。
According to this, when the operation of the heating unit is stopped, the working fluid condensed by the condenser flows into the heat exchanger for equipment from the lower connection portion through the liquid phase passage by its own weight. The working fluid absorbs heat from the target device inside the device heat exchanger and evaporates. The working fluid that has become a gas phase flows from the upper connection portion through the gas phase passage to the condenser. The working fluid is condensed again in the condenser, and flows into the heat exchanger for equipment through the liquid phase passage. By such circulation of the working fluid, the device temperature adjustment device can cool the target device.
一方、加熱部が作動すると、流体通路の作動流体が蒸発し、上接続部から機器用熱交換器に流入する。機器用熱交換器の内側で気相の作動流体は対象機器に放熱して凝縮する。液相となった作動流体は下接続部から流体通路に流れる。その作動流体は、流体通路で加熱部に加熱されて再び蒸発し、機器用熱交換器に流入する。このような作動流体の循環により、機器温調装置は、対象機器の暖機を行うことが可能である。
On the other hand, when the heating section is activated, the working fluid in the fluid passage evaporates and flows into the equipment heat exchanger from the upper connection section. Inside the equipment heat exchanger, the gas phase working fluid dissipates heat to the target equipment and condenses. The working fluid in the liquid phase flows from the lower connection portion to the fluid passage. The working fluid is heated by the heating section in the fluid passage, evaporates again, and flows into the equipment heat exchanger. By such a circulation of the working fluid, the device temperature control device can warm up the target device.
この機器温調装置は、対象機器の暖機時に、機器用熱交換器の外側にある流体通路の作動流体を加熱部により加熱する構成である。そのため、流体通路で気化した作動流体の蒸気が機器用熱交換器に供給されるため、機器用熱交換器の内側で作動流体の蒸気温度のばらつきが抑制される。したがって、この機器温調装置は、対象機器を均一に暖機することが可能である。その結果、対象機器が組電池である場合、組電池の入出力特性の低下を防ぎ、その組電池の劣化や破損を抑制することができる。
This equipment temperature control device is configured to heat the working fluid in the fluid passage outside the equipment heat exchanger by the heating unit when the target equipment is warmed up. For this reason, the working fluid vapor evaporated in the fluid passage is supplied to the equipment heat exchanger, so that the variation in the steam temperature of the working fluid is suppressed inside the equipment heat exchanger. Therefore, this device temperature control device can warm up the target device uniformly. As a result, when the target device is an assembled battery, it is possible to prevent a decrease in input / output characteristics of the assembled battery, and to suppress deterioration and breakage of the assembled battery.
また、この機器温調装置は、対象機器の冷却時に、凝縮器→液相通路→下接続部→機器用熱交換器→上接続部→気相通路→凝縮器の順に作動流体が循環する。一方、対象機器の暖機時に、流体通路→上接続部→機器用熱交換器→下接続部→流体通路の順に作動流体が循環する。すなわち、この機器温調装置は、対象機器の冷却時と暖機時のいずれにおいても、作動流体の流れる流路がループ状に形成される。そのため、液相の作動流体と気相の作動流体とが一つの流路を対向して流れることが防がれる。したがって、この機器温調装置は、作動流体を円滑に循環させることで、対象機器の暖機と冷却を高効率に行うことができる。
Also, in this equipment temperature control device, when the target equipment is cooled, the working fluid circulates in the order of condenser → liquid phase passage → lower connection portion → device heat exchanger → upper connection portion → gas phase passage → condenser. On the other hand, when the target device is warmed up, the working fluid circulates in the order of fluid passage → upper connection portion → device heat exchanger → lower connection portion → fluid passage. That is, in this device temperature control device, the flow path for the working fluid is formed in a loop shape both when the target device is cooled and when it is warmed up. Therefore, it is possible to prevent the liquid-phase working fluid and the gas-phase working fluid from flowing in the same flow path. Therefore, this apparatus temperature control apparatus can warm up and cool the target apparatus with high efficiency by smoothly circulating the working fluid.
さらに、この機器温調装置は、機器用熱交換器の上接続部と下接続部とを接続する流体通路の高さ方向に、加熱部を設けるための空間が確保されるので、機器用熱交換器より下側に加熱部等を設ける必要性が低減される。したがって、この機器温調装置は、車両への搭載性を向上することができる。
Furthermore, this device temperature control device secures a space for providing a heating portion in the height direction of the fluid passage connecting the upper connection portion and the lower connection portion of the heat exchanger for the device. The need to provide a heating unit or the like below the exchanger is reduced. Therefore, this apparatus temperature control apparatus can improve the mounting property to a vehicle.

An upper connection provided in the upper part of the gravitational direction of the heat exchanger for equipment, and through which the working fluid flows in or out;
A lower connection part that is provided in a lower part of the heat exchanger for equipment than the upper connection part in the direction of gravity, and into which working fluid flows in or out;
A fluid passage communicating the upper connection portion and the lower connection portion of the equipment heat exchanger;
A heating unit capable of heating the liquid-phase working fluid flowing through the fluid passage;
And a control device that operates the heating unit when warming up the target device.
これによれば、この機器温調装置は、対象機器の暖機時に、機器用熱交換器の外側にある流体通路の作動流体を加熱部により加熱する構成である。そのため、流体通路で気化した作動流体の蒸気が機器用熱交換器に供給されるため、機器用熱交換器の内側で作動流体の蒸気温度のばらつきが抑制される。したがって、この機器温調装置は、対象機器を均一に暖機することが可能である。その結果、対象機器が組電池である場合、組電池の入出力特性の低下を防ぎ、その組電池の劣化や破損を抑制することができる。
According to this, this apparatus temperature control apparatus is the structure which heats the working fluid of the fluid path in the outer side of the apparatus heat exchanger with a heating part at the time of warming up of object apparatus. For this reason, the working fluid vapor evaporated in the fluid passage is supplied to the equipment heat exchanger, so that the variation in the steam temperature of the working fluid is suppressed inside the equipment heat exchanger. Therefore, this device temperature control device can warm up the target device uniformly. As a result, when the target device is an assembled battery, it is possible to prevent a decrease in input / output characteristics of the assembled battery, and to suppress deterioration and breakage of the assembled battery.
また、この機器温調装置は、対象機器の暖機時に、流体通路→上接続部→機器用熱交換器→下接続部→流体通路の順に作動流体が循環する。すなわち、この機器温調装置は、対象機器の暖機時に、作動流体の流れる流路がループ状に形成される。そのため、液相の作動流体と気相の作動流体とが一つの流路を対向して流れることが防がれる。したがって、この機器温調装置は、作動流体を円滑に循環させることで、対象機器の暖機を高効率に行うことができる。
Also, in this equipment temperature control device, when the target equipment is warmed up, the working fluid circulates in the order of the fluid passage → the upper connection portion → the equipment heat exchanger → the lower connection portion → the fluid passage. That is, in this device temperature control apparatus, the flow path through which the working fluid flows is formed in a loop when the target device is warmed up. Therefore, it is possible to prevent the liquid-phase working fluid and the gas-phase working fluid from flowing in the same flow path. Therefore, this device temperature control device can warm up the target device with high efficiency by smoothly circulating the working fluid.
さらに、この機器温調装置は、機器用熱交換器の上接続部と下接続部とを接続する流体通路の高さ方向に、加熱部を設けるための空間が確保されるので、機器用熱交換器より下側に加熱部等を設ける必要性が低減される。したがって、この機器温調装置は、車両への搭載性を向上することができる。
Furthermore, this device temperature control device secures a space for providing a heating portion in the height direction of the fluid passage connecting the upper connection portion and the lower connection portion of the heat exchanger for the device. The need to provide a heating unit or the like below the exchanger is reduced. Therefore, this apparatus temperature control apparatus can improve the mounting property to a vehicle.
また、別の観点によれば、作動流体の液相と気相との相変化により対象機器の温度を調整する機器温調装置であって、

A fluid passage communicating the upper connection portion and the lower connection portion of the equipment heat exchanger;
Heat that is provided in the fluid passage at a height position across the level of the working fluid level inside the equipment heat exchanger, and that can selectively supply cold or hot heat to the working fluid that flows through the fluid passage. A supply member.
対象機器の冷却時に作動流体が蒸発し、対象機器の暖機時に作動流体が凝縮するように、対象機器と作動流体とが熱交換可能に構成された機器用熱交換器と、
機器用熱交換器のうち重力方向上側の部位に設けられ、作動流体が流入または流出する上接続部と、

機器用熱交換器の内側にある作動流体の液面の高さを跨ぐ高さ方向の位置で流体通路に設けられ、流体通路を流れる作動流体に対し冷熱または温熱を選択的に供給可能な熱供給部材と、を備える。 Further, according to another aspect, the device temperature adjustment device for adjusting the temperature of the target device by a phase change between the liquid phase and the gas phase of the working fluid,
A heat exchanger for equipment configured to allow heat exchange between the target device and the working fluid so that the working fluid evaporates when the target device is cooled and the working fluid is condensed when the target device is warmed up;
An upper connection provided in the upper part of the gravitational direction of the heat exchanger for equipment, and through which the working fluid flows in or out;

A fluid passage communicating the upper connection portion and the lower connection portion of the equipment heat exchanger;
Heat that is provided in the fluid passage at a height position across the level of the working fluid level inside the equipment heat exchanger, and that can selectively supply cold or hot heat to the working fluid that flows through the fluid passage. A supply member.
これによれば、機器温調装置は、熱供給部材により、流体通路を流れる作動流体に対し冷熱または温熱を選択的に供給することで、対象機器の暖機と冷却のどちらも行うことが可能である。したがって、この機器温調装置は、部品点数を少なくし、配管等の構成を簡素にすることで、小型化、軽量、低コストを実現できる。
According to this, the device temperature control device can perform both warm-up and cooling of the target device by selectively supplying cold heat or heat to the working fluid flowing through the fluid passage by the heat supply member. It is. Therefore, this equipment temperature control device can achieve downsizing, light weight, and low cost by reducing the number of parts and simplifying the configuration of piping and the like.
具体的には、機器温調装置は、対象機器の冷却時に、流体通路を流れる作動流体に対し熱供給部材から冷熱が供給されると、流体通路の作動流体が凝縮する。そして、その流体通路で凝縮した液相の作動流体と機器用熱交換器内の液相の作動流体とのヘッド差により、流体通路の液相の作動流体は下接続部から機器用熱交換器に流入する。機器用熱交換器内の作動流体は、対象機器から吸熱して蒸発し、その気相となった作動流体は上接続部から流体通路に流れる。流体通路の作動流体は、熱供給部材により冷却されて再び凝縮し、下接続部から機器用熱交換器に流入する。このような作動流体の循環により、機器温調装置は、対象機器の冷却を行うことが可能である。
Specifically, in the device temperature control device, when cooling heat is supplied from the heat supply member to the working fluid flowing through the fluid passage when the target device is cooled, the working fluid in the fluid passage is condensed. Then, due to the head difference between the liquid-phase working fluid condensed in the fluid passage and the liquid-phase working fluid in the equipment heat exchanger, the liquid-phase working fluid in the fluid passage passes from the lower connection portion to the equipment heat exchanger. Flow into. The working fluid in the equipment heat exchanger absorbs heat from the target equipment and evaporates, and the working fluid in the gas phase flows from the upper connection portion to the fluid passage. The working fluid in the fluid passage is cooled by the heat supply member, condensed again, and flows into the equipment heat exchanger from the lower connection portion. By such circulation of the working fluid, the device temperature adjustment device can cool the target device.
一方、対象機器の暖機時に、流体通路を流れる作動流体に対し熱供給部材から温熱が供給されると、流体通路の作動流体が蒸発し、上接続部から機器用熱交換器に流入する。機器用熱交換器の内側で気相の作動流体は対象機器に放熱して凝縮する。そして、機器用熱交換器内で凝縮した液相の作動流体と流体通路の液相の作動流体とのヘッド差により、機器用熱交換器の液相の作動流体は下接続部から流体通路に流れる。その作動流体は、流体通路で熱供給部材により加熱されて再び蒸発し、機器用熱交換器に流入する。このような作動流体の循環により、機器温調装置は、対象機器の暖機を行うことが可能である。
On the other hand, when the heat is supplied from the heat supply member to the working fluid flowing through the fluid passage when the target device is warmed up, the working fluid in the fluid passage evaporates and flows into the equipment heat exchanger from the upper connection portion. Inside the equipment heat exchanger, the gas phase working fluid dissipates heat to the target equipment and condenses. Due to the head difference between the liquid-phase working fluid condensed in the equipment heat exchanger and the liquid-phase working fluid in the fluid passage, the liquid-phase working fluid in the equipment heat exchanger is transferred from the lower connection portion to the fluid passage. Flowing. The working fluid is heated by the heat supply member in the fluid passage, evaporates again, and flows into the equipment heat exchanger. By such a circulation of the working fluid, the device temperature control device can warm up the target device.
この機器温調装置は、対象機器の暖機時に、機器用熱交換器の外側にある流体通路の作動流体を熱供給部材により加熱する構成である。そのため、流体通路で気化した作動流体の蒸気が機器用熱交換器に供給されるため、機器用熱交換器の内側で作動流体の蒸気温度のばらつきが抑制される。したがって、この機器温調装置は、対象機器を均一に暖機することが可能である。その結果、対象機器が組電池である場合、組電池の入出力特性の低下を防ぎ、その組電池の劣化や破損を抑制することができる。
This equipment temperature control device is configured to heat the working fluid in the fluid passage outside the equipment heat exchanger by the heat supply member when the target equipment is warmed up. For this reason, the working fluid vapor evaporated in the fluid passage is supplied to the equipment heat exchanger, so that the variation in the steam temperature of the working fluid is suppressed inside the equipment heat exchanger. Therefore, this device temperature control device can warm up the target device uniformly. As a result, when the target device is an assembled battery, it is possible to prevent a decrease in input / output characteristics of the assembled battery, and to suppress deterioration and breakage of the assembled battery.
また、この機器温調装置は、対象機器の冷却時に、流体通路→下接続部→機器用熱交換器→上接続部→流体通路の順に作動流体が循環する。一方、対象機器の暖機時に、流体通路→上接続部→機器用熱交換器→下接続部→流体通路の順に作動流体が循環する。すなわち、この機器温調装置は、対象機器の冷却時と暖機時のいずれにおいても、作動流体の流れる流路がループ状に形成される。そのため、液相の作動流体と気相の作動流体とが一つの流路を対向して流れることが防がれる。したがって、この機器温調装置は、作動流体を円滑に循環させることで、対象機器の暖機と冷却を高効率に行うことができる。
Also, in this equipment temperature control device, when the target equipment is cooled, the working fluid circulates in the order of fluid passage → lower connection portion → device heat exchanger → upper connection portion → fluid passage. On the other hand, when the target device is warmed up, the working fluid circulates in the order of fluid passage → upper connection portion → device heat exchanger → lower connection portion → fluid passage. That is, in this device temperature control device, the flow path for the working fluid is formed in a loop shape both when the target device is cooled and when it is warmed up. Therefore, it is possible to prevent the liquid-phase working fluid and the gas-phase working fluid from flowing in the same flow path. Therefore, this apparatus temperature control apparatus can warm up and cool the target apparatus with high efficiency by smoothly circulating the working fluid.
また、この機器温調装置は、機器用熱交換器の上接続部と下接続部とを接続する流体通路の高さ方向に、熱供給部材を設けるための空間が確保されるので、機器用熱交換器より下側に配管や部品を設ける必要性が低減される。したがって、この機器温調装置は、車両への搭載性を向上することができる。
In addition, this device temperature control device secures a space for providing a heat supply member in the height direction of the fluid passage connecting the upper connection portion and the lower connection portion of the equipment heat exchanger. The need to provide piping and components below the heat exchanger is reduced. Therefore, this apparatus temperature control apparatus can improve the mounting property to a vehicle.
以下、本開示の実施形態について図面を参照しつつ説明する。なお、以下の各実施形態相互において、互いに同一もしくは均等である部分には、同一符号を付し、その説明を省略する。
Hereinafter, embodiments of the present disclosure will be described with reference to the drawings. In the following embodiments, parts that are the same or equivalent to each other are given the same reference numerals, and descriptions thereof are omitted.
(第1実施形態)
本実施形態の機器温調装置は、電気自動車やハイブリッド車などの電動車両(以下、単に「車両」という)に搭載されるものである。図1に示すように、機器温調装置1は、車両に搭載される二次電池2(以下、「組電池2」という)を冷却する冷却装置として機能する。また、機器温調装置1は、組電池2を暖機する暖機装置としても機能する。 (First embodiment)
The apparatus temperature control device of this embodiment is mounted on an electric vehicle (hereinafter simply referred to as “vehicle”) such as an electric vehicle or a hybrid vehicle. As shown in FIG. 1, the devicetemperature control device 1 functions as a cooling device that cools a secondary battery 2 (hereinafter referred to as “assembled battery 2”) mounted on a vehicle. Moreover, the apparatus temperature control apparatus 1 functions also as a warming-up apparatus which warms up the assembled battery 2. FIG.
本実施形態の機器温調装置は、電気自動車やハイブリッド車などの電動車両(以下、単に「車両」という)に搭載されるものである。図1に示すように、機器温調装置1は、車両に搭載される二次電池2(以下、「組電池2」という)を冷却する冷却装置として機能する。また、機器温調装置1は、組電池2を暖機する暖機装置としても機能する。 (First embodiment)
The apparatus temperature control device of this embodiment is mounted on an electric vehicle (hereinafter simply referred to as “vehicle”) such as an electric vehicle or a hybrid vehicle. As shown in FIG. 1, the device
まず、機器温調装置1が温度調整を行う対象機器としての組電池2について説明する。
First, a description will be given of the assembled battery 2 as a target device for which the device temperature control device 1 performs temperature adjustment.
機器温調装置1を搭載する車両では、組電池2を主要構成部品として含む蓄電装置(言い換えれば、電池パック)に蓄えた電力がインバータなどを介して車両走行用モータに供給される。組電池2は車両走行中などに電力供給等を行うと自己発熱する。組電池2は高温になると、十分な機能を発揮できないだけでなく、劣化が促進されることから、自己発熱が少なくなるように出力および入力を制限する必要がある。このため、組電池2の出力および入力を確保するためには、組電池2を所定の温度以下に維持するための冷却装置が必要となる。
In a vehicle equipped with the device temperature control device 1, electric power stored in a power storage device (in other words, a battery pack) including the assembled battery 2 as a main component is supplied to a vehicle driving motor via an inverter or the like. The assembled battery 2 self-heats when power is supplied while the vehicle is running. When the assembled battery 2 becomes high temperature, not only cannot a sufficient function be exhibited, but also deterioration is promoted. Therefore, it is necessary to limit output and input so that self-heating is reduced. For this reason, in order to ensure the output and input of the assembled battery 2, a cooling device for maintaining the assembled battery 2 below a predetermined temperature is required.
また、夏季などの外気温が高い季節では、車両走行中だけでなく、駐車放置中などにも電池温度は上昇する。また、組電池2は車両の床下やトランクルーム下などに配置されることが多く、組電池2に与えられる単位時間当たりの熱量は小さいものの、長時間の放置により電池温度は徐々に上昇する。組電池2を高温状態で放置すると組電池2の寿命が短くなるので、車両の駐車中等にも組電池2の温度を所定の温度以下に維持することが望まれている。
In addition, in high seasons such as summer, the battery temperature rises not only when the vehicle is running but also when parked. In addition, the assembled battery 2 is often arranged under the floor of a vehicle, under a trunk room, etc., and although the amount of heat per unit time given to the assembled battery 2 is small, the battery temperature gradually rises when left for a long time. If the assembled battery 2 is left in a high temperature state, the life of the assembled battery 2 is shortened. Therefore, it is desired to maintain the temperature of the assembled battery 2 at a predetermined temperature or less even during parking of the vehicle.
さらに、組電池2は、複数の電池セル21により構成されている。組電池2は、各電池セル21の温度にばらつきがあると電池セル21の劣化に偏りが生じ、蓄電性能が低下してしまう。これは、組電池2が電池セル21の直列接続体を含んでいることで、最も劣化した電池セル21の特性に合わせて組電池2の入出力特性が決まるからである。そのため、長期間にわたって組電池2に所望の性能を発揮させるためには、複数の電池セル21相互間の温度ばらつきを低減させる均温化が重要となる。
Furthermore, the assembled battery 2 is composed of a plurality of battery cells 21. In the assembled battery 2, if the temperature of each battery cell 21 varies, the deterioration of the battery cell 21 is biased, and the power storage performance decreases. This is because the input / output characteristics of the assembled battery 2 are determined in accordance with the characteristics of the battery cell 21 that is most deteriorated because the assembled battery 2 includes the series connection body of the battery cells 21. Therefore, in order to make the assembled battery 2 exhibit desired performance over a long period of time, it is important to equalize the temperature so as to reduce the temperature variation among the plurality of battery cells 21.
また、一般に、組電池2を冷却する他の冷却装置として、送風機による空冷式の冷却手段、蒸気圧縮式の冷凍サイクルの冷熱を利用した冷却手段が一般的である。しかし、送風機による空冷式の冷却手段は、車室内の空気を送風するだけなので、冷却能力は低い。また、送風機による送風は、空気の顕熱で組電池2を冷却するので、空気流れの上流と下流との間で温度差が大きくなり、複数の電池セル21同士の温度ばらつきを十分に抑制できない。また、冷凍サイクルの冷熱を利用した冷却手段は、冷却能力は高いものの、車両の駐車中に、電力消費量の多いコンプレッサ等を駆動させることが必要となる。このことは、電力消費量の増大、騒音の増大等を招くことになるため好ましくない。
In general, as other cooling devices for cooling the assembled battery 2, an air-cooling cooling means using a blower and a cooling means using the cold heat of a vapor compression refrigeration cycle are generally used. However, since the air-cooled cooling means using the blower only blows air in the passenger compartment, the cooling capacity is low. Moreover, since the air blower cools the assembled battery 2 with the sensible heat of air, the temperature difference between the upstream and downstream of the air flow becomes large, and the temperature variation between the plurality of battery cells 21 cannot be sufficiently suppressed. . Moreover, although the cooling means using the cold heat of the refrigeration cycle has a high cooling capacity, it is necessary to drive a compressor or the like that consumes a large amount of power while the vehicle is parked. This is undesirable because it leads to an increase in power consumption and an increase in noise.
そこで、本実施形態の機器温調装置1は、作動流体をコンプレッサにより強制循環させることなく、作動流体の自然循環によって組電池2の温度を調整するサーモサイフォン方式を採用している。
Therefore, the device temperature control apparatus 1 of the present embodiment employs a thermosiphon system that adjusts the temperature of the assembled battery 2 by natural circulation of the working fluid without forcibly circulating the working fluid by a compressor.
次に、機器温調装置1の構成について説明する。
Next, the configuration of the device temperature control device 1 will be described.
図1に示すように、機器温調装置1は、作動流体が循環する流体循環回路4と、その流体循環回路4の動作を制御する制御装置5を備えている。
As shown in FIG. 1, the device temperature control device 1 includes a fluid circulation circuit 4 through which a working fluid circulates and a control device 5 that controls the operation of the fluid circulation circuit 4.
流体循環回路4は、作動流体の蒸発および凝縮により熱移動を行うヒートパイプであり、詳細には、気相の作動流体が流れる流路と液相の作動流体が流れる流路とが分離されたループ型のサーモサイフォンである。流体循環回路4は、機器用熱交換器10、凝縮器30、液相通路40、気相通路50および流体通路60などが互いに接続され、閉じられた流体回路として構成されている。また、流体通路60には、作動流体を加熱するための加熱部61が設けられている。
The fluid circulation circuit 4 is a heat pipe that performs heat transfer by evaporation and condensation of the working fluid. Specifically, the flow path through which the gas-phase working fluid flows and the flow path through which the liquid-phase working fluid flows are separated. It is a loop-type thermosiphon. The fluid circulation circuit 4 is configured as a closed fluid circuit in which the equipment heat exchanger 10, the condenser 30, the liquid phase passage 40, the gas phase passage 50, the fluid passage 60, and the like are connected to each other. Further, the fluid passage 60 is provided with a heating unit 61 for heating the working fluid.
流体循環回路4には、その内部が真空排気された状態で、所定量の作動流体が封入されている。作動流体として、例えば、蒸気圧縮式の冷凍サイクルで利用されるHFO-1234yfまたはHFC-134aなどのフロン系冷媒が採用される。なお、図1の矢印DGは、流体循環回路4が車両に搭載された状態における重力方向を示している。
The fluid circulation circuit 4 is filled with a predetermined amount of working fluid in a state where the inside is evacuated. As the working fluid, for example, a fluorocarbon refrigerant such as HFO-1234yf or HFC-134a used in a vapor compression refrigeration cycle is employed. An arrow DG in FIG. 1 indicates the direction of gravity in a state where the fluid circulation circuit 4 is mounted on the vehicle.
流体循環回路4の作動流体の充填量は、後述する暖機時に、機器用熱交換器10の高さ方向の中央付近に液面が形成されるように調整されている。図1では、暖機時の液面の高さの一例を、一点鎖線FLで示している。
The filling amount of the working fluid in the fluid circulation circuit 4 is adjusted so that the liquid level is formed in the vicinity of the center in the height direction of the equipment heat exchanger 10 during warm-up described later. In FIG. 1, an example of the height of the liquid level during warm-up is indicated by a one-dot chain line FL.
図2~図4に示すように、機器用熱交換器10は、筒状の上タンク11と、筒状の下タンク12と、その上タンク11と下タンク12とを連通する流路を有する複数のチューブ131により構成されている。なお、複数のチューブ131に代えて、板状の部材の内側に複数の流路を形成したものにより、上タンク11と下タンク12とを接続してもよい。機器用熱交換器10の各構成部材は、例えばアルミニウム、銅等の熱伝導性の高い金属から形成されている。なお、機器用熱交換器10の各構成部材は、金属以外の熱伝導性の高い材料により構成することも可能である。機器用熱交換器10のうち、複数のチューブ131または板状の部材により構成された部位を、熱交換部13ということとする。
As shown in FIGS. 2 to 4, the equipment heat exchanger 10 has a cylindrical upper tank 11, a cylindrical lower tank 12, and a flow path that connects the upper tank 11 and the lower tank 12. It is composed of a plurality of tubes 131. Instead of the plurality of tubes 131, the upper tank 11 and the lower tank 12 may be connected by a plurality of flow paths formed inside the plate-like member. Each component of the equipment heat exchanger 10 is formed of a metal having high thermal conductivity such as aluminum or copper. In addition, each structural member of the heat exchanger 10 for apparatuses can also be comprised with materials with high heat conductivity other than a metal. The part comprised by the some tube 131 or the plate-shaped member among the heat exchangers 10 for apparatuses shall be called the heat exchange part 13. FIG.

The assembled battery 2 is installed outside the heat exchanging unit 13 via an electrically insulating heat conductive sheet 14. The heat conductive sheet 14 ensures insulation between the heat exchanging unit 13 and the assembled battery 2 and reduces the thermal resistance between the heat exchanging unit 13 and the assembled battery 2. In the present embodiment, in the assembled battery 2, the surface 23 opposite to the surface 25 on which the terminals 22 are provided is installed in the heat exchange unit 13 via the heat conductive sheet 14. The plurality of battery cells 21 constituting the assembled battery 2 are arranged in a direction crossing the gravitational direction. Thus, the plurality of battery cells 21 are uniformly cooled and heated by heat exchange with the working fluid inside the equipment heat exchanger 10.
なお、後述する第15~第18実施形態で説明するように、組電池2の設置方法は、図1~図3に示したものに限らず、組電池2の他の面が熱伝導シート14を介して熱交換部13に設置されていてもよい。なお、組電池2を構成する各電池セル21の個数、形状なども、図1~図3に示したものに限らず、任意のものを採用することができる。

第1上接続部151には、気相通路50が接続されている。気相通路50は、凝縮器30の流入口31と、機器用熱交換器10の第1上接続部151とを連通する通路である。一方、第1下接続部161には、液相通路40が接続されている。液相通路40は、凝縮器30の流出口32と、機器用熱交換器10の第1上接続部151とを連通する通路である。なお、気相通路50と液相通路40は、便宜上の呼び名であり、気相または液相の作動流体のみが流れる通路という意味ではない。すなわち、気相通路50と液相通路40のいずれにも、気相と液相の両方の作動流体が流れることがある。また、気相通路50と液相通路40の形状等は、車両への搭載性を考慮して適宜変更可能である。
The gas phase passage 50 is connected to the first upper connection portion 151. The gas phase passage 50 is a passage that communicates the inlet 31 of the condenser 30 and the first upper connection portion 151 of the equipment heat exchanger 10. On the other hand, the liquid phase passage 40 is connected to the first lower connection portion 161. The liquid phase passage 40 is a passage that communicates the outlet 32 of the condenser 30 with the first upper connection portion 151 of the equipment heat exchanger 10. The gas phase passage 50 and the liquid phase passage 40 are names for convenience, and do not mean a passage through which only a gas phase or liquid phase working fluid flows. That is, both the gas phase and the liquid phase working fluid may flow in both the gas phase passage 50 and the liquid phase passage 40. In addition, the shapes of the gas phase passage 50 and the liquid phase passage 40 can be appropriately changed in consideration of the mounting property on the vehicle.
凝縮器30は、機器用熱交換器10より重力方向上側に配置される。凝縮器30のうち上側の部位に流入口31が設けられ、凝縮器30のうち下側の部位に流出口32が設けられている。凝縮器30は、気相通路50を通って流入口31から凝縮器30の内側に流入した気相の作動流体と、所定の受熱流体とを熱交換させるための熱交換器である。本実施形態の凝縮器30は、送風ファン33から送風された空気と気相の作動流体とを熱交換させる空冷式の熱交換器である。すなわち、本実施形態では、所定の受熱流体は空気である。なお、後述する実施形態で説明するように、受熱流体は空気に限るものではなく、例えば冷凍サイクルを循環する冷媒、または、冷却水回路を循環する冷却水など、種々の流体を採用することが可能である。
The condenser 30 is disposed above the apparatus heat exchanger 10 in the gravity direction. An inlet 31 is provided in the upper part of the condenser 30, and an outlet 32 is provided in the lower part of the condenser 30. The condenser 30 is a heat exchanger for exchanging heat between a gas-phase working fluid that has flowed into the condenser 30 from the inlet 31 through the gas-phase passage 50 and a predetermined heat-receiving fluid. The condenser 30 of this embodiment is an air-cooled heat exchanger that exchanges heat between the air blown from the blower fan 33 and the gas-phase working fluid. That is, in the present embodiment, the predetermined heat receiving fluid is air. As will be described in the embodiments described later, the heat receiving fluid is not limited to air, and various fluids such as a refrigerant circulating in the refrigeration cycle or a cooling water circulating in the cooling water circuit may be adopted. Is possible.
送風ファン33は、車室外の空気または車室内の空気を凝縮器30に向けて流すことが可能である。送風ファン33は、制御装置5からの制御信号に基づいて送風能力が制御される。気相の作動流体は、凝縮器30を通過する空気に放熱することで凝縮する。液相となった作動流体は、自重によって、流出口32から液相通路40を流下し、機器用熱交換器10に流入する。
The blower fan 33 can flow air outside the passenger compartment or air inside the passenger compartment toward the condenser 30. The air blowing capacity of the blower fan 33 is controlled based on a control signal from the control device 5. The gas phase working fluid is condensed by releasing heat to the air passing through the condenser 30. The working fluid in the liquid phase flows down from the outlet 32 through the liquid phase passage 40 by its own weight, and flows into the equipment heat exchanger 10.
液相通路40の途中には、液相通路40を流れる作動流体の流れを遮断することの可能な流体制御弁70が設けられている。本実施形態の流体制御弁70は、電磁弁であり、制御装置5から伝送される制御信号により、流路断面積が調整される。流体制御弁70が液相通路40を流れる作動流体の流れを遮断すると、流体制御弁70より重力方向上側の液相通路40から凝縮器30に亘って液相の作動流体が貯まり、それ以降、凝縮器30による作動流体の放熱が抑制されるか、または略停止される。したがって、流体制御弁70は、凝縮器30による作動流体の放熱を抑制可能な放熱抑制部として機能するものである。
In the middle of the liquid phase passage 40, a fluid control valve 70 capable of blocking the flow of the working fluid flowing through the liquid phase passage 40 is provided. The fluid control valve 70 of the present embodiment is an electromagnetic valve, and the flow path cross-sectional area is adjusted by a control signal transmitted from the control device 5. When the fluid control valve 70 cuts off the flow of the working fluid flowing through the liquid phase passage 40, the liquid phase working fluid is accumulated from the liquid phase passage 40 above the fluid control valve 70 in the gravity direction to the condenser 30, and thereafter. The heat radiation of the working fluid by the condenser 30 is suppressed or substantially stopped. Therefore, the fluid control valve 70 functions as a heat dissipation suppression unit that can suppress the heat dissipation of the working fluid by the condenser 30.
第2上接続部152と第2下接続部162には、流体通路60が接続されている。流体通路60は、その経路上に凝縮器30を含むことなく、機器用熱交換器10の上接続部15と下接続部16とを接続する通路であるので、バイパス通路とも呼ばれる。後述する第20実施形態で説明するように、流体通路60は、第2上接続部152と第2下接続部162とを接続するものに限定されず、気相通路50の途中と液相通路40の途中とを接続してもよい。
The fluid passage 60 is connected to the second upper connection portion 152 and the second lower connection portion 162. Since the fluid passage 60 is a passage connecting the upper connection portion 15 and the lower connection portion 16 of the equipment heat exchanger 10 without including the condenser 30 on the route, the fluid passage 60 is also referred to as a bypass passage. As will be described in a twentieth embodiment to be described later, the fluid passage 60 is not limited to connecting the second upper connection portion 152 and the second lower connection portion 162, and the middle of the gas phase passage 50 and the liquid phase passage. The middle of 40 may be connected.
流体通路60には、流体通路60を流れる液相の作動流体を加熱することの可能な加熱部61が設けられている。本実施形態の加熱部61は、通電により発熱する電気ヒータで構成されている。加熱部61への通電のオンオフは、制御装置5からの制御信号に応じて制御される。加熱部61は、流体通路60が上下方向に延びている部位に設けられている。これにより、加熱部61が流体通路60の作動流体を加熱すると、蒸気となった作動流体は、流体通路60を重力方向上側に流れ、第2上接続部152から機器用熱交換器10に流入する。
The fluid passage 60 is provided with a heating unit 61 capable of heating the liquid-phase working fluid flowing through the fluid passage 60. The heating unit 61 of the present embodiment is configured by an electric heater that generates heat when energized. On / off of energization to the heating unit 61 is controlled according to a control signal from the control device 5. The heating unit 61 is provided at a portion where the fluid passage 60 extends in the vertical direction. As a result, when the heating unit 61 heats the working fluid in the fluid passage 60, the working fluid that has become vapor flows through the fluid passage 60 upward in the direction of gravity and flows into the equipment heat exchanger 10 from the second upper connection portion 152. To do.
制御装置5は、プロセッサ、メモリ(例えば、ROM、RAM)を含むマイクロコンピュータと、その周辺回路から構成されている。なお、制御装置5のメモリは、非遷移的実体的記憶媒体で構成されている。制御装置5は、上述した流体循環回路4が備える加熱部61、送風ファン33、および流体制御弁70などの各機器の作動を制御する。
The control device 5 includes a microcomputer including a processor and a memory (for example, ROM, RAM) and its peripheral circuits. Note that the memory of the control device 5 is composed of a non-transitional tangible storage medium. The control device 5 controls the operation of each device such as the heating unit 61, the blower fan 33, and the fluid control valve 70 included in the fluid circulation circuit 4 described above.
続いて、機器温調装置1の作動について説明する。
Subsequently, the operation of the device temperature control device 1 will be described.
図5および図6に示すように、組電池2は、所定の最適温度範囲よりも低温になると、内部抵抗が増加し、出力特性と入力特性が共に低下する。また、組電池2は、所定の最適温度範囲よりも高温になると、出力特性と入力特性が共に低下すると共に、劣化や破損に至るおそれがある。そのため、組電池2に所望の性能を発揮させるためには、組電池2が所定の最適温度範囲よりも低温となるときに組電池2を暖機し、組電池2が所定の最適温度範囲よりも高温となるときに組電池2を冷却することが必要である。
As shown in FIG. 5 and FIG. 6, when the assembled battery 2 becomes cooler than a predetermined optimum temperature range, the internal resistance increases, and both the output characteristics and the input characteristics deteriorate. Further, when the assembled battery 2 becomes hotter than a predetermined optimum temperature range, both the output characteristics and the input characteristics are degraded, and there is a possibility that the battery pack 2 may be deteriorated or broken. Therefore, in order for the assembled battery 2 to exhibit the desired performance, the assembled battery 2 is warmed up when the assembled battery 2 becomes lower in temperature than the predetermined optimum temperature range, and the assembled battery 2 exceeds the predetermined optimum temperature range. However, it is necessary to cool the assembled battery 2 when the temperature becomes high.
<冷却時の作動>
図7では、機器温調装置1が組電池2を冷却するときの作動流体の流れを実線および破線の矢印で示している。組電池2の冷却時、制御装置5は、加熱部61への通電をオフし、加熱部61の作動を停止させる。また、制御装置5は、流体制御弁70を開弁し、液相通路40に作動流体が流れるようにする。さらに、制御装置5は、車両が停車中の時には、凝縮器30に送風する送風ファン33の電源をオンする。ただし、制御装置5は、車両が走行中の時には、走行風が凝縮器30に流れるため、送風ファン33の電源をオフする。 <Operation during cooling>
In FIG. 7, the flow of the working fluid when the devicetemperature control device 1 cools the assembled battery 2 is indicated by solid and broken arrows. At the time of cooling the assembled battery 2, the control device 5 turns off the power supply to the heating unit 61 and stops the operation of the heating unit 61. Further, the control device 5 opens the fluid control valve 70 so that the working fluid flows through the liquid phase passage 40. Furthermore, the control device 5 turns on the power of the blower fan 33 that blows air to the condenser 30 when the vehicle is stopped. However, when the vehicle is traveling, the control device 5 turns off the power of the blower fan 33 because the traveling wind flows into the condenser 30.
図7では、機器温調装置1が組電池2を冷却するときの作動流体の流れを実線および破線の矢印で示している。組電池2の冷却時、制御装置5は、加熱部61への通電をオフし、加熱部61の作動を停止させる。また、制御装置5は、流体制御弁70を開弁し、液相通路40に作動流体が流れるようにする。さらに、制御装置5は、車両が停車中の時には、凝縮器30に送風する送風ファン33の電源をオンする。ただし、制御装置5は、車両が走行中の時には、走行風が凝縮器30に流れるため、送風ファン33の電源をオフする。 <Operation during cooling>
In FIG. 7, the flow of the working fluid when the device
これにより、凝縮器30で凝縮した液相の作動流体は、自重により液相通路40を流れ、第1下接続部161から機器用熱交換器10の下タンク12に流入する。下タンク12に流入した作動流体は、熱交換部13を構成する複数のチューブ131に分流し、組電池2を構成する各電池セル21と熱交換することにより蒸発する。この過程で電池セル21は、作動流体の蒸発潜熱により冷却される。その後、気相となった作動流体は機器用熱交換器10の上タンク11で合流し、第1上接続部151から気相通路50を通り、凝縮器30に流れる。
Thereby, the liquid-phase working fluid condensed in the condenser 30 flows through the liquid-phase passage 40 due to its own weight, and flows into the lower tank 12 of the equipment heat exchanger 10 from the first lower connection portion 161. The working fluid that has flowed into the lower tank 12 is divided into a plurality of tubes 131 that constitute the heat exchanging unit 13, and is evaporated by exchanging heat with the battery cells 21 that constitute the assembled battery 2. In this process, the battery cell 21 is cooled by the latent heat of vaporization of the working fluid. Thereafter, the working fluid that has become a gas phase joins in the upper tank 11 of the equipment heat exchanger 10, and flows from the first upper connection portion 151 through the gas phase passage 50 to the condenser 30.
上述の通り、組電池2の冷却時の作動流体の流れは、凝縮器30→液相通路40→下タンク12→熱交換部13→上タンク11→気相通路50→凝縮器30の順となる。すなわち、機器用熱交換器10と凝縮器30を通るループ状の流路が形成される。
As described above, the flow of the working fluid during cooling of the assembled battery 2 is in the order of the condenser 30 → the liquid phase passage 40 → the lower tank 12 → the heat exchange unit 13 → the upper tank 11 → the gas phase passage 50 → the condenser 30. Become. That is, a loop-shaped flow path that passes through the equipment heat exchanger 10 and the condenser 30 is formed.
なお、組電池2の冷却時に、作動流体の一部は流体通路60にも供給されるが、加熱部61への通電をオフしていることから、流体通路60では作動流体が気化しないため、流体通路60に作動流体の流れは殆ど生じない。
In addition, when the assembled battery 2 is cooled, a part of the working fluid is also supplied to the fluid passage 60, but since the energization to the heating unit 61 is turned off, the working fluid is not vaporized in the fluid passage 60. There is almost no flow of working fluid in the fluid passage 60.
<暖機時の作動>
図8では、機器温調装置1が組電池2を暖機するときの作動流体の流れを実線および破線の矢印で示している。組電池2の暖機時、制御装置5は、加熱部61への通電をオンし、加熱部61を作動させる。また、制御装置5は、流体制御弁70を閉弁し、液相通路40の作動流体の流れを遮断する。 <Operation during warm-up>
In FIG. 8, the flow of the working fluid when the devicetemperature control device 1 warms up the assembled battery 2 is indicated by solid and broken arrows. When the assembled battery 2 is warmed up, the control device 5 turns on the energization of the heating unit 61 and operates the heating unit 61. In addition, the control device 5 closes the fluid control valve 70 and blocks the flow of the working fluid in the liquid phase passage 40.
図8では、機器温調装置1が組電池2を暖機するときの作動流体の流れを実線および破線の矢印で示している。組電池2の暖機時、制御装置5は、加熱部61への通電をオンし、加熱部61を作動させる。また、制御装置5は、流体制御弁70を閉弁し、液相通路40の作動流体の流れを遮断する。 <Operation during warm-up>
In FIG. 8, the flow of the working fluid when the device
加熱部61が作動することにより、流体通路60の作動流体が気化し、蒸気となった作動流体は、流体通路60を重力方向上側に流れ、第2上接続部152から機器用熱交換器10の上タンク11に流入する。気相の作動流体は、温度が低い方へ流れる性質から、低温の電池セル21が接触している複数のチューブ131に分流し、低温の各電池セル21と熱交換することにより凝縮する。この過程で電池セル21は、作動流体の凝縮潜熱により暖機(すなわち加熱)される。その後、液相となった作動流体は機器用熱交換器10の下タンク12で合流し、第2下接続部162から流体通路60に流れる。上述の通り、組電池2の暖機時の作動流体の流れは、流体通路60→上タンク11→熱交換部13→下タンク12→流体通路60の順となる。すなわち、凝縮器30を通ることなく、機器用熱交換器10と流体通路60を通るループ状の流路が形成される。
When the heating unit 61 is operated, the working fluid in the fluid passage 60 is vaporized, and the working fluid that has become a vapor flows through the fluid passage 60 upward in the gravitational direction, and from the second upper connection portion 152, the equipment heat exchanger 10. Into the upper tank 11. The gas-phase working fluid is condensed by being divided into a plurality of tubes 131 in contact with the low-temperature battery cells 21 and exchanging heat with each of the low-temperature battery cells 21 due to the property of flowing in a lower temperature. In this process, the battery cell 21 is warmed up (ie, heated) by the latent heat of condensation of the working fluid. Thereafter, the working fluid in a liquid phase is merged in the lower tank 12 of the equipment heat exchanger 10 and flows from the second lower connecting portion 162 to the fluid passage 60. As described above, the flow of the working fluid when the assembled battery 2 is warmed up is in the order of the fluid passage 60 → the upper tank 11 → the heat exchange unit 13 → the lower tank 12 → the fluid passage 60. That is, a loop-shaped flow path that passes through the equipment heat exchanger 10 and the fluid passage 60 is formed without passing through the condenser 30.
なお、組電池2の暖機時に、気相の作動流体の一部は気相通路50と凝縮器30にも供給されるが、流体制御弁70を閉弁しているので、流体制御弁70より重力方向上側の液相通路40から凝縮器30に亘り液相の作動流体が貯まる。これにより、凝縮器30による作動流体の放熱が抑制または略停止され、気相通路50と液相通路40に作動流体の流れは殆ど生じない。
When the assembled battery 2 is warmed up, a part of the gas-phase working fluid is also supplied to the gas-phase passage 50 and the condenser 30, but since the fluid control valve 70 is closed, the fluid control valve 70 A liquid-phase working fluid accumulates from the liquid-phase passage 40 on the upper side in the gravity direction to the condenser 30. Thereby, the heat radiation of the working fluid by the condenser 30 is suppressed or substantially stopped, and the flow of the working fluid hardly occurs in the gas phase passage 50 and the liquid phase passage 40.
上述したように、暖機時には、流体制御弁70より重力方向上側の液相通路40から凝縮器30に亘り液相の作動流体が貯まった状態となる。この状態で、機器用熱交換器10の熱交換部13の中央部付近に液面FLが形成されるよう、流体循環回路4への作動流体の封入量、および、流体制御弁70の取付位置が調整されている。
As described above, at the time of warming up, the liquid phase working fluid is accumulated from the liquid phase passage 40 above the fluid control valve 70 in the gravity direction to the condenser 30. In this state, the amount of the working fluid sealed in the fluid circulation circuit 4 and the mounting position of the fluid control valve 70 so that the liquid level FL is formed near the center of the heat exchanger 13 of the equipment heat exchanger 10. Has been adjusted.
本実施形態の機器温調装置1は、冷却時と暖機時で、機器用熱交換器10のチューブ131を流れる作動流体の流れを逆方向にするよう切り替え、機器用熱交換器10を流れる作動流体の液相と気相との相変化により組電池2の温度を調整する。その際、機器温調装置1は、冷却時には機器用熱交換器10を蒸発器として使用し、暖機時には機器用熱交換器10を凝縮器30として使用することで、同一の機器用熱交換器10を使用して冷却と暖機を可能としている。
The apparatus temperature control apparatus 1 of the present embodiment switches the flow of the working fluid flowing through the tube 131 of the apparatus heat exchanger 10 in the opposite direction during cooling and warming up, and flows through the apparatus heat exchanger 10. The temperature of the assembled battery 2 is adjusted by the phase change between the liquid phase and the gas phase of the working fluid. At that time, the equipment temperature control device 1 uses the equipment heat exchanger 10 as an evaporator at the time of cooling, and uses the equipment heat exchanger 10 as a condenser 30 at the time of warming up, so that the same equipment heat exchange is performed. The vessel 10 is used for cooling and warming up.
以上説明した本実施形態の機器温調装置1は、次の作用効果を奏する。
The apparatus temperature control apparatus 1 of this embodiment demonstrated above has the following effects.
(1)本実施形態の機器温調装置1は、組電池2の暖機時に、機器用熱交換器10の外側に設けた流体通路60を流れる作動流体を加熱部61により加熱する構成である。そのため、流体通路60で気化した作動流体の蒸気が機器用熱交換器10に供給されるため、機器用熱交換器10の内側で作動流体の蒸気温度のばらつきが抑制される。したがって、この機器温調装置1は、組電池2を均一に暖機することが可能である。その結果、組電池2の入出力特性の低下を防ぎ、その組電池2の劣化や破損を抑制することができる。
(1) The apparatus temperature control apparatus 1 of this embodiment is the structure which heats the working fluid which flows through the fluid channel | path 60 provided in the outer side of the apparatus heat exchanger 10 with the heating part 61 at the time of warming-up of the assembled battery 2. FIG. . Therefore, since the vapor of the working fluid vaporized in the fluid passage 60 is supplied to the equipment heat exchanger 10, variation in the vapor temperature of the working fluid is suppressed inside the equipment heat exchanger 10. Therefore, this apparatus temperature control apparatus 1 can warm up the assembled battery 2 uniformly. As a result, the input / output characteristics of the assembled battery 2 can be prevented from being lowered, and the assembled battery 2 can be prevented from being degraded or damaged.
(2)本実施形態の機器温調装置1は、組電池2の冷却時に、凝縮器30→液相通路40→下接続部16→機器用熱交換器10→上接続部15→気相通路50→凝縮器30の順に作動流体が循環する。一方、組電池2の暖機時に、流体通路60→上接続部15→機器用熱交換器10→下接続部16→流体通路60の順に作動流体が循環する。すなわち、この機器温調装置1は、組電池2の冷却時と暖機時のいずれにおいても、作動流体の流れる流路がループ状に形成される。そのため、液相の作動流体と気相の作動流体とが一つの流路を対向して流れることが防がれる。したがって、この機器温調装置1は、作動流体を円滑に循環させることで、組電池2の暖機と冷却を高効率に行うことができる。
(2) When the assembled battery 2 is cooled, the device temperature control device 1 of the present embodiment is configured such that the condenser 30 → the liquid phase passage 40 → the lower connection portion 16 → the device heat exchanger 10 → the upper connection portion 15 → the gas phase passage. The working fluid circulates in the order of 50 → condenser 30. On the other hand, when the assembled battery 2 is warmed up, the working fluid circulates in the order of the fluid passage 60 → the upper connection portion 15 → the equipment heat exchanger 10 → the lower connection portion 16 → the fluid passage 60. That is, in the device temperature control apparatus 1, the flow path through which the working fluid flows is formed in a loop shape regardless of whether the assembled battery 2 is cooled or warmed up. Therefore, it is possible to prevent the liquid-phase working fluid and the gas-phase working fluid from flowing in the same flow path. Therefore, this apparatus temperature control apparatus 1 can warm up and cool the assembled battery 2 with high efficiency by smoothly circulating the working fluid.
(3)本実施形態の機器温調装置1は、機器用熱交換器10の上接続部15と下接続部16とを接続する流体通路60の高さ方向に、加熱部61を設けるための空間が確保されるので、機器用熱交換器10より下側に加熱部61を設ける必要性が低減される。したがって、この機器温調装置1は、車両への搭載性を向上することができる。
(3) The apparatus temperature control apparatus 1 of this embodiment is for providing the heating part 61 in the height direction of the fluid passage 60 that connects the upper connection part 15 and the lower connection part 16 of the apparatus heat exchanger 10. Since space is ensured, the necessity of providing the heating unit 61 below the heat exchanger for equipment 10 is reduced. Therefore, this equipment temperature control apparatus 1 can improve the mounting property to a vehicle.
(4)本実施形態の機器温調装置1は、凝縮器30による作動流体の放熱を抑制可能な放熱抑制部としての流体制御弁70を備えている。これによれば、組電池2の暖機時に流体制御弁70を閉弁することで、流体制御弁70から凝縮器30に液相の作動流体が貯まり、凝縮器30による作動流体の放熱が抑制される。それに伴い、気相通路50、凝縮器30および液相通路40の作動流体の循環が抑制される。そのため、組電池2の暖機時に、流体通路60側のループに作動流体を流すことが可能である。したがって、この機器温調装置1は、作動流体を円滑に循環させることで、組電池2の暖機を高効率に行うことができる。
(4) The device temperature control apparatus 1 of the present embodiment includes a fluid control valve 70 as a heat radiation suppressing unit capable of suppressing the heat radiation of the working fluid by the condenser 30. According to this, by closing the fluid control valve 70 when the assembled battery 2 is warmed up, liquid-phase working fluid is stored in the condenser 30 from the fluid control valve 70, and heat dissipation of the working fluid by the condenser 30 is suppressed. Is done. Accordingly, the circulation of the working fluid in the gas phase passage 50, the condenser 30 and the liquid phase passage 40 is suppressed. Therefore, when the assembled battery 2 is warmed up, it is possible to flow the working fluid through the loop on the fluid passage 60 side. Therefore, this apparatus temperature control apparatus 1 can warm up the assembled battery 2 with high efficiency by smoothly circulating the working fluid.
(5)本実施形態では、加熱部61は、流体通路60のうち、重力方向上下に延びている部位に設けられる。これによれば、加熱部61により加熱されて気化した作動流体は、流体通路60を重力方向上側に速やかに流れる。そのため、気相の作動流体が流体通路60から第2下接続部162側へ逆流することが防がれる。したがって、この機器温調装置1は、作動流体を円滑に循環させることで、組電池2の暖機を高効率に行うことができる。
(5) In the present embodiment, the heating unit 61 is provided in a portion of the fluid passage 60 that extends vertically in the gravity direction. According to this, the working fluid heated and vaporized by the heating unit 61 quickly flows through the fluid passage 60 upward in the gravity direction. Therefore, the working fluid in the gas phase is prevented from flowing backward from the fluid passage 60 to the second lower connection portion 162 side. Therefore, this apparatus temperature control apparatus 1 can warm up the assembled battery 2 with high efficiency by smoothly circulating the working fluid.

A nineteenth embodiment will be described. In the nineteenth embodiment, a part of the configuration of the
図27および図28に示すように、第19実施形態では、流体通路60は、経路の途中に、流体通路60を流れる液相の作動流体を貯める貯液部63を有している。貯液部63は、少なくとも一部が、機器用熱交換器10の上接続部15と下接続部16との高さ範囲内に位置している。これにより、機器温調装置1は、組電池2の冷却および暖機に必要な作動流体の量を貯液部63に貯め、その貯液部63の液面FLの高さを調整することで、組電池2の加熱時と冷却時で、機器用熱交換器10の作動流体の液面FLの高さを容易に調整可能である。
As shown in FIGS. 27 and 28, in the nineteenth embodiment, the fluid passage 60 has a liquid storage portion 63 for storing a liquid-phase working fluid flowing through the fluid passage 60 in the middle of the passage. At least a part of the liquid storage part 63 is located within the height range of the upper connection part 15 and the lower connection part 16 of the equipment heat exchanger 10. Thereby, the apparatus temperature control apparatus 1 stores the amount of the working fluid necessary for cooling and warming up the assembled battery 2 in the liquid storage unit 63, and adjusting the height of the liquid level FL of the liquid storage unit 63. The height of the liquid level FL of the working fluid in the equipment heat exchanger 10 can be easily adjusted during heating and cooling of the assembled battery 2.
図28は、機器用熱交換器10と流体通路60の断面図である。貯液部63は、流体通路60の経路のうち一部の内径を大きくすることで形成されている。これにより、流体通路60に対し、貯液部63を簡素な構成で設けることができる。

第20実施形態について説明する。第20実施形態は、第1実施形態に対して、流体通路60の構成等を変更したものであり、その他については第1実施形態と同様であるため、第1実施形態と異なる部分についてのみ説明する。 (20th embodiment)
A twentieth embodiment will be described. In the twentieth embodiment, the configuration and the like of thefluid passage 60 are changed with respect to the first embodiment, and the other parts are the same as those in the first embodiment. Therefore, only the parts different from the first embodiment are described. To do.
第20実施形態について説明する。第20実施形態は、第1実施形態に対して、流体通路60の構成等を変更したものであり、その他については第1実施形態と同様であるため、第1実施形態と異なる部分についてのみ説明する。 (20th embodiment)
A twentieth embodiment will be described. In the twentieth embodiment, the configuration and the like of the
図29および図30に示すように、第20実施形態では、流体通路60は、貯液部63を有している。流体通路60が有する貯液部63は、液相通路40に連通している。また、流体通路60のうち、貯液部63とは反対側の部位は、三方切替弁71を介して気相通路50に連通している。
As shown in FIGS. 29 and 30, in the twentieth embodiment, the fluid passage 60 has a liquid storage portion 63. The liquid storage portion 63 included in the fluid passage 60 communicates with the liquid phase passage 40. In addition, a portion of the fluid passage 60 opposite to the liquid storage portion 63 communicates with the gas phase passage 50 via the three-way switching valve 71.
図29では、機器温調装置1が組電池2を冷却するときの作動流体の流れを実線および破線の矢印で示している。第1実施形態で説明したように、組電池2の冷却時、制御装置5は、加熱部61への通電をオフし、加熱部61の作動を停止させる。また、制御装置5は、流体制御弁70を開弁し、液相通路40に作動流体が流れるようにする。さらに、制御装置5は、車両が停車中の時には、凝縮器30に送風する送風ファン33の電源をオンする。ただし、制御装置5は、車両が走行中の時には、走行風が凝縮器30に流れるため、送風ファン33の電源をオフする。
29, the flow of the working fluid when the device temperature control device 1 cools the assembled battery 2 is indicated by solid and broken arrows. As described in the first embodiment, when the assembled battery 2 is cooled, the control device 5 turns off the power supply to the heating unit 61 and stops the operation of the heating unit 61. Further, the control device 5 opens the fluid control valve 70 so that the working fluid flows through the liquid phase passage 40. Furthermore, the control device 5 turns on the power of the blower fan 33 that blows air to the condenser 30 when the vehicle is stopped. However, when the vehicle is traveling, the control device 5 turns off the power of the blower fan 33 because the traveling wind flows into the condenser 30.
さらに、第20実施形態では、組電池2の冷却時、制御装置5は、三方切替弁71を制御する。三方切替弁71の動作により、三方切替弁71よりも上接続部15側の気相通路50と、三方切替弁71よりも凝縮器30側の気相通路50とが連通すると共に、流体通路60と気相通路50との連通が遮断される。
Furthermore, in the twentieth embodiment, the control device 5 controls the three-way switching valve 71 when the assembled battery 2 is cooled. Due to the operation of the three-way switching valve 71, the gas phase passage 50 on the upper connecting portion 15 side with respect to the three-way switching valve 71 and the gas phase passage 50 on the condenser 30 side with respect to the three-way switching valve 71 communicate with each other. And the gas phase passage 50 are disconnected.
これにより、組電池2の冷却時の作動流体の流れは、凝縮器30→液相通路40→下タンク12→熱交換部13→上タンク11→気相通路50→凝縮器30の順となる。すなわち、機器用熱交換器10と凝縮器30を通るループ状の流路が形成される。
Thereby, the flow of the working fluid at the time of cooling the assembled battery 2 is in the order of the condenser 30 → the liquid phase passage 40 → the lower tank 12 → the heat exchange unit 13 → the upper tank 11 → the gas phase passage 50 → the condenser 30. . That is, a loop-shaped flow path that passes through the equipment heat exchanger 10 and the condenser 30 is formed.
これに対し、図30では、機器温調装置1が組電池2を暖機するときの作動流体の流れを実線および破線の矢印で示している。第1実施形態で説明したように、組電池2の暖機時、制御装置5は、加熱部61への通電をオンし、加熱部61を作動させる。また、制御装置5は、流体制御弁70を閉弁し、液相通路40の作動流体の流れを遮断する。
On the other hand, in FIG. 30, the flow of the working fluid when the device temperature control device 1 warms up the assembled battery 2 is indicated by solid and broken arrows. As described in the first embodiment, when the assembled battery 2 is warmed up, the control device 5 turns on the energization of the heating unit 61 and operates the heating unit 61. In addition, the control device 5 closes the fluid control valve 70 and blocks the flow of the working fluid in the liquid phase passage 40.
さらに、第20実施形態では、組電池2の暖機時、制御装置5は、三方切替弁71を制御する。三方切替弁71の動作により、三方切替弁71よりも上接続側の気相通路50と流体通路60とが連通すると共に、三方切替弁71よりも凝縮器30側の気相通路50と流体通路60との連通が遮断される。
Furthermore, in the twentieth embodiment, the control device 5 controls the three-way switching valve 71 when the assembled battery 2 is warmed up. By the operation of the three-way switching valve 71, the gas-phase passage 50 and the fluid passage 60 on the upper connection side of the three-way switching valve 71 communicate with each other, and the gas-phase passage 50 and the fluid passage on the condenser 30 side of the three-way switching valve 71. Communication with 60 is cut off.
これにより、組電池2の暖機時の作動流体の流れは、流体通路60→上タンク11→熱交換部13→下タンク12→流体通路60の順となる。すなわち、凝縮器30を通ることなく、機器用熱交換器10と流体通路60を通るループ状の流路が形成される。
Thereby, the flow of the working fluid when the assembled battery 2 is warmed up is in the order of the fluid passage 60 → the upper tank 11 → the heat exchange unit 13 → the lower tank 12 → the fluid passage 60. That is, a loop-shaped flow path that passes through the equipment heat exchanger 10 and the fluid passage 60 is formed without passing through the condenser 30.
(第21実施形態)
第21実施形態について説明する。第21実施形態は、第1~第20実施形態に対して、機器用熱交換器10の構成を変更したものであり、その他については第1~第20実施形態と同様であるため、第1~第20実施形態と異なる部分についてのみ説明する。 (21st Embodiment)
A twenty-first embodiment will be described. The twenty-first embodiment is obtained by changing the configuration of theequipment heat exchanger 10 with respect to the first to twentieth embodiments, and is otherwise the same as the first to twentieth embodiments. Only parts different from the twentieth embodiment will be described.
第21実施形態について説明する。第21実施形態は、第1~第20実施形態に対して、機器用熱交換器10の構成を変更したものであり、その他については第1~第20実施形態と同様であるため、第1~第20実施形態と異なる部分についてのみ説明する。 (21st Embodiment)
A twenty-first embodiment will be described. The twenty-first embodiment is obtained by changing the configuration of the
図31に示すように、第21実施形態の機器用熱交換器10は、上タンク、下タンクおよび複数のチューブを有していない。第21実施形態の機器用熱交換器10は、単一の容器17により構成されている。このような第21実施形態の機器用熱交換器10でも、第1~第20実施形態で説明した機器用熱交換器10と同様の作用効果を奏することができる。
As shown in FIG. 31, the equipment heat exchanger 10 of the 21st embodiment does not have an upper tank, a lower tank, and a plurality of tubes. The equipment heat exchanger 10 according to the twenty-first embodiment is configured by a single container 17. The device heat exchanger 10 according to the twenty-first embodiment can achieve the same effects as the device heat exchanger 10 described in the first to twentieth embodiments.
(第22実施形態)
第22実施形態について説明する。第22実施形態は、第1実施形態に対して、機器温調装置1の冷却機能を除いたものであり、その他については第1実施形態と同様であるため、第1実施形態と異なる部分についてのみ説明する。 (Twenty-second embodiment)
A twenty-second embodiment will be described. The twenty-second embodiment is the same as the first embodiment except for the cooling function of the devicetemperature control device 1 with respect to the first embodiment, and the other parts are the same as the first embodiment. Only explained.
第22実施形態について説明する。第22実施形態は、第1実施形態に対して、機器温調装置1の冷却機能を除いたものであり、その他については第1実施形態と同様であるため、第1実施形態と異なる部分についてのみ説明する。 (Twenty-second embodiment)
A twenty-second embodiment will be described. The twenty-second embodiment is the same as the first embodiment except for the cooling function of the device
図32に示すように、第22実施形態の機器用熱交換器10は、凝縮器30、液相通路40、気相通路50を備えていない。第22実施形態の機器用熱交換器10が備える流体循環回路4は、機器用熱交換器10と流体通路60とが閉じられた流体回路として構成されている。
32, the equipment heat exchanger 10 according to the twenty-second embodiment does not include the condenser 30, the liquid phase passage 40, and the gas phase passage 50. The fluid circulation circuit 4 included in the equipment heat exchanger 10 of the twenty-second embodiment is configured as a fluid circuit in which the equipment heat exchanger 10 and the fluid passage 60 are closed.
流体通路60は、一端が機器用熱交換器10の上接続部15に接続され、他端が機器用熱交換器10の下接続部16に接続されている。流体通路60には、流体通路60を流れる液相の作動流体を加熱するための加熱部61が設けられている。
The fluid passage 60 has one end connected to the upper connection portion 15 of the equipment heat exchanger 10 and the other end connected to the lower connection portion 16 of the equipment heat exchanger 10. The fluid passage 60 is provided with a heating unit 61 for heating the liquid-phase working fluid flowing through the fluid passage 60.
組電池2の暖機時、制御装置5は、加熱部61への通電をオンし、加熱部61を作動させる。加熱部61により加熱されて蒸気となった作動流体は、流体通路60を重力方向上側に流れ、上接続部15から機器用熱交換器10の上タンク11に流入する。気相の作動流体は、温度が低い方へ流れる性質から、低温の電池セル21が接触している複数のチューブ131に分流し、低温の各電池セル21と熱交換することにより凝縮する。この過程で電池セル21は、作動流体の凝縮潜熱により暖機(すなわち加熱)される。その後、液相となった作動流体は機器用熱交換器10の下タンク12で合流し、下接続部16から流体通路60に流れる。上述の通り、組電池2の暖機時の作動流体の流れは、流体通路60→上タンク11→熱交換部13→下タンク12→流体通路60の順となる。すなわち、機器用熱交換器10と流体通路60を通るループ状の流路が形成される。
When the assembled battery 2 is warmed up, the control device 5 turns on the power to the heating unit 61 and operates the heating unit 61. The working fluid that is heated by the heating unit 61 and becomes vapor flows in the fluid passage 60 upward in the gravity direction, and flows into the upper tank 11 of the equipment heat exchanger 10 from the upper connection unit 15. The gas-phase working fluid is condensed by being divided into a plurality of tubes 131 in contact with the low-temperature battery cells 21 and exchanging heat with each of the low-temperature battery cells 21 due to the property of flowing in a lower temperature. In this process, the battery cell 21 is warmed up (ie, heated) by the latent heat of condensation of the working fluid. Thereafter, the working fluid in a liquid phase joins in the lower tank 12 of the equipment heat exchanger 10 and flows from the lower connection portion 16 to the fluid passage 60. As described above, the flow of the working fluid when the assembled battery 2 is warmed up is in the order of the fluid passage 60 → the upper tank 11 → the heat exchange unit 13 → the lower tank 12 → the fluid passage 60. That is, a loop-shaped flow path that passes through the equipment heat exchanger 10 and the fluid passage 60 is formed.
第22実施形態の機器温調装置1は、上述した第1実施形態で説明した機器温調装置1の暖機時の作用効果と、同様の作用効果を奏することが可能である。また、第22実施形態の構成に対し、上述した第1~第21実施形態で説明した構成を適宜組み合わせることも可能である。
The device temperature adjustment device 1 of the 22nd embodiment can exhibit the same effect as the operation effect during the warm-up of the device temperature adjustment device 1 described in the first embodiment. In addition, the configuration described in the first to 21st embodiments can be appropriately combined with the configuration of the 22nd embodiment.
(第23実施形態)
第23実施形態について図33~図39を参照して説明する。上述の第1~第22実施形態で説明したように、機器温調装置1が対象機器としての組電池2の暖機を行う際、加熱部61により加熱されて気相となった作動流体は、流体通路60から上接続部15を経由して機器用熱交換器10に流入する。その気相の作動流体は、機器用熱交換器10内で低温の各電池セル21に放熱して凝縮し、液相となる。その際、機器用熱交換器10内では、複数のチューブ131内の上方部分で作動流体の凝縮量が多く、複数のチューブ131内の下方部分では液相の作動流体が底部および側壁に溜まることから作動流体の凝縮量が少ない。そのため、各電池セル21の上方部分は作動流体の凝縮潜熱による加熱量が大きいが、各電池セル21の下方部分は上方部分に比べて加熱量が小さい。その結果、電池セル21の上方部分と下方部分とで温度のばらつき(すなわち温度分布)が大きくなると、組電池2が充放電を行う際に、電池セル21の温度の高い上方部分に電流集中が発生することが懸念される。 (23rd Embodiment)
A twenty-third embodiment will be described with reference to FIGS. As described in the first to twenty-second embodiments, when the devicetemperature control apparatus 1 warms up the assembled battery 2 as the target device, the working fluid heated to the gas phase by the heating unit 61 is Then, the fluid flows from the fluid passage 60 into the equipment heat exchanger 10 via the upper connection portion 15. The working fluid in the gas phase dissipates heat to the low-temperature battery cells 21 in the equipment heat exchanger 10 and condenses into a liquid phase. At that time, in the equipment heat exchanger 10, the working fluid has a large amount of condensation in the upper part of the plurality of tubes 131, and the liquid-phase working fluid accumulates on the bottom and side walls in the lower part of the plurality of tubes 131. Therefore, the amount of condensation of the working fluid is small. Therefore, although the upper part of each battery cell 21 has a large heating amount due to the latent heat of condensation of the working fluid, the lower part of each battery cell 21 has a smaller heating amount than the upper part. As a result, when temperature variation (that is, temperature distribution) between the upper part and the lower part of the battery cell 21 increases, current concentration occurs in the upper part where the temperature of the battery cell 21 is high when the assembled battery 2 is charged and discharged. There are concerns about the occurrence.
第23実施形態について図33~図39を参照して説明する。上述の第1~第22実施形態で説明したように、機器温調装置1が対象機器としての組電池2の暖機を行う際、加熱部61により加熱されて気相となった作動流体は、流体通路60から上接続部15を経由して機器用熱交換器10に流入する。その気相の作動流体は、機器用熱交換器10内で低温の各電池セル21に放熱して凝縮し、液相となる。その際、機器用熱交換器10内では、複数のチューブ131内の上方部分で作動流体の凝縮量が多く、複数のチューブ131内の下方部分では液相の作動流体が底部および側壁に溜まることから作動流体の凝縮量が少ない。そのため、各電池セル21の上方部分は作動流体の凝縮潜熱による加熱量が大きいが、各電池セル21の下方部分は上方部分に比べて加熱量が小さい。その結果、電池セル21の上方部分と下方部分とで温度のばらつき(すなわち温度分布)が大きくなると、組電池2が充放電を行う際に、電池セル21の温度の高い上方部分に電流集中が発生することが懸念される。 (23rd Embodiment)
A twenty-third embodiment will be described with reference to FIGS. As described in the first to twenty-second embodiments, when the device
そこで、以下に説明する第23実施形態から第26実施形態は、機器温調装置1が組電池2の暖機を行う際に、組電池2の温度分布を抑制することを目的としている。
Therefore, the twenty-third to twenty-sixth embodiments described below are intended to suppress the temperature distribution of the assembled battery 2 when the device temperature control device 1 warms up the assembled battery 2.
図33に示すように、本実施形態の機器温調装置1の構成は、第8実施形態で説明した構成と同じである。すなわち、加熱部61は、通電により発熱する電気ヒータで構成されている。
As shown in FIG. 33, the configuration of the device temperature adjustment device 1 of the present embodiment is the same as the configuration described in the eighth embodiment. That is, the heating unit 61 is configured by an electric heater that generates heat when energized.
なお、図33では、制御装置5に接続される各センサおよび制御装置5の構成が例示されている。制御装置5には、1個または複数の電池温度センサ101、作動流体温度センサ102、および、ヒータ温度センサ103などから伝送される信号が入力される。1個または複数の電池温度センサ101は、電池の温度を検出するものである。作動流体温度センサ102は、サーモサイフォン回路を循環する作動流体の温度を検出するものである。ヒータ温度センサ103は、加熱部61の温度を検出するものである。また、制御装置5は、組電池2の温度分布の大きさを判定する温度分布判定部110、加熱部61への通電時間を検出するヒータ通電時間検出部111、加熱部61へ供給される電力を検出するヒータ電力検出部112などを有している。なお、制御装置5、温度分布判定部110、ヒータ通電時間検出部111、ヒータ電力検出部112などは、一体に構成されていてもよく、それぞれが別々に構成されていてもよい。このことは、後述する実施形態でも同じである。
In addition, in FIG. 33, the structure of each sensor connected to the control apparatus 5 and the control apparatus 5 is illustrated. The control device 5 receives signals transmitted from one or more battery temperature sensors 101, working fluid temperature sensors 102, heater temperature sensors 103, and the like. One or more battery temperature sensors 101 detect the temperature of the battery. The working fluid temperature sensor 102 detects the temperature of the working fluid circulating in the thermosiphon circuit. The heater temperature sensor 103 detects the temperature of the heating unit 61. In addition, the control device 5 includes a temperature distribution determination unit 110 that determines the size of the temperature distribution of the assembled battery 2, a heater energization time detection unit 111 that detects an energization time to the heating unit 61, and electric power supplied to the heating unit 61. And a heater power detection unit 112 for detecting. Note that the control device 5, the temperature distribution determination unit 110, the heater energization time detection unit 111, the heater power detection unit 112, and the like may be configured integrally, or may be configured separately. This is the same in the embodiments described later.
図33および図35は、機器温調装置1が組電池2の暖機を行う前の状態を示している。制御装置5は、加熱部61への通電を停止している。この状態で、図35に示すように、機器用熱交換器10内の作動流体の液面FLは、電池セル21の高さ方向で比較的低い位置にある。
33 and 35 show a state before the device temperature control device 1 warms up the assembled battery 2. The control device 5 stops energizing the heating unit 61. In this state, as shown in FIG. 35, the liquid level FL of the working fluid in the equipment heat exchanger 10 is at a relatively low position in the height direction of the battery cell 21.
次に、図34および図36は、機器温調装置1が組電池2の暖機を行っているときの状態を示している。組電池2の暖機時、制御装置5は、加熱部61への通電を行い、加熱部61により作動流体を加熱する。また、制御装置5は、流体制御弁70を閉弁し、気相通路50の作動流体の流れを遮断する。
Next, FIG. 34 and FIG. 36 show a state when the device temperature control device 1 is warming up the assembled battery 2. When the assembled battery 2 is warmed up, the control device 5 energizes the heating unit 61 and heats the working fluid by the heating unit 61. In addition, the control device 5 closes the fluid control valve 70 and blocks the flow of the working fluid in the gas phase passage 50.
図34では、組電池2の暖機時の作動流体の流れを実線および破線の矢印で示している。加熱部61が流体通路60の作動流体を加熱すると、流体通路60の作動流体は蒸発し、上接続部15から機器用熱交換器10の上タンク11に流入する。機器用熱交換器10の複数のチューブ131内で気相の作動流体は組電池2に放熱して凝縮する。この過程で電池セル21は、作動流体の凝縮潜熱により暖機(すなわち加熱)される。機器用熱交換器10内で凝縮した作動流体の液面FLと流体通路60の作動流体の液面FLとのヘッド差により、機器用熱交換器10の液相の作動流体は下タンク12から下接続部16を経由して流体通路60に流れる。その作動流体は、流体通路60で加熱部61により加熱されて再び蒸発し、機器用熱交換器10に流入する。このような作動流体の循環により、機器温調装置1は、組電池2の暖機を行うことが可能である。
34, the flow of the working fluid when the assembled battery 2 is warmed up is indicated by solid and broken arrows. When the heating unit 61 heats the working fluid in the fluid passage 60, the working fluid in the fluid passage 60 evaporates and flows into the upper tank 11 of the equipment heat exchanger 10 from the upper connection portion 15. In the plurality of tubes 131 of the equipment heat exchanger 10, the gas phase working fluid dissipates heat to the assembled battery 2 and condenses. In this process, the battery cell 21 is warmed up (ie, heated) by the latent heat of condensation of the working fluid. Due to the head difference between the liquid level FL of the working fluid condensed in the equipment heat exchanger 10 and the liquid level FL of the working fluid in the fluid passage 60, the liquid phase working fluid of the equipment heat exchanger 10 flows from the lower tank 12. The fluid flows to the fluid passage 60 via the lower connection portion 16. The working fluid is heated by the heating unit 61 in the fluid passage 60 and evaporated again, and flows into the equipment heat exchanger 10. The device temperature control device 1 can warm up the assembled battery 2 by circulating such working fluid.
図36に示すように、組電池2の暖機時、機器用熱交換器10の複数のチューブ131内では、気相の作動流体が凝縮され、チューブ131内の側壁137を伝って重力方向下側へ流れる。そのため、チューブ131内の側壁137に形成される作動流体の液膜は、上方から下方に向かって次第に厚くなる。したがって、機器用熱交換器10内の上方では作動流体の液膜が薄いので電池セル21に対する作動流体の凝縮潜熱による加熱能力が比較的大きい。これに対し、機器用熱交換器10の下方では作動流体の液膜が厚くなることから電池セル21に対する作動流体の凝縮潜熱による加熱能力が比較的小さくなる。また、機器用熱交換器10の下方では作動流体の液面FLが高くなり、その液面FLより下では電池セル21に対する作動流体の凝縮潜熱による加熱能力が非常に小さくなる。そのため、暖機時間の経過と共に、各電池セル21は、上方部分と下方部分の温度分布が次第に大きくなる。
As shown in FIG. 36, when the assembled battery 2 is warmed up, the working fluid in the vapor phase is condensed in the plurality of tubes 131 of the equipment heat exchanger 10, and travels along the side wall 137 in the tubes 131 and moves downward in the gravity direction. Flows to the side. Therefore, the liquid film of the working fluid formed on the side wall 137 in the tube 131 gradually increases from the upper side to the lower side. Therefore, since the liquid film of the working fluid is thin above the apparatus heat exchanger 10, the heating capacity of the battery cells 21 due to the latent heat of condensation of the working fluid is relatively large. On the other hand, since the liquid film of the working fluid is thicker below the equipment heat exchanger 10, the heating capacity of the battery cell 21 due to the latent heat of condensation of the working fluid becomes relatively small. In addition, the liquid level FL of the working fluid is high below the equipment heat exchanger 10, and the heating capacity of the battery cell 21 due to the latent heat of condensation of the working fluid is very small below the liquid level FL. Therefore, as the warm-up time elapses, the temperature distribution of the upper part and the lower part of each battery cell 21 gradually increases.
そこで、本実施形態では、組電池2の暖機開始から一定時間経過後、制御装置5は、加熱部61への通電を停止する制御を行う。これにより、流体通路60から機器用熱交換器10への作動流体の流入が停止する。そのため、機器用熱交換器10内の液面FLと流体通路60の液面FLとのヘッド差がなくなるので、図37に示すように、機器用熱交換器10内の作動流体の液面FLが下がる。また、図37の矢印αに示すように機器用熱交換器10のチューブ131内の側壁137の液膜は下方に流下し、さらに、矢印βに示すようにチューブ131内の上部側壁の液膜は電池セル21のうちそれまでに加熱された部位との熱交換により蒸発する。したがって、チューブ131内の側壁137の液膜が薄くなり、チューブ131内の側壁137が気相の作動流体に露出する面積が広くなる。これにより、チューブ131内の上部から下部に亘り広い範囲で作動流体の凝縮が可能になる。そのため、チューブ131内の上方の比較的高温な部位で蒸発した作動流体が、チューブ131内の下方の比較的低温な部位で凝縮し、各電池セル21は、上方部分と下方部分の温度分布が次第に小さくなる。また、各電池セル21内部での熱伝導も生じることから、時間の経過と共に各電池セル21の均温化が促進される。
Therefore, in the present embodiment, the control device 5 performs control to stop energization of the heating unit 61 after a predetermined time has elapsed from the start of warming up of the assembled battery 2. Thereby, the inflow of the working fluid from the fluid passage 60 to the equipment heat exchanger 10 is stopped. Therefore, there is no head difference between the liquid level FL in the equipment heat exchanger 10 and the liquid level FL in the fluid passage 60, so that the working fluid level FL in the equipment heat exchanger 10 as shown in FIG. Go down. 37, the liquid film on the side wall 137 in the tube 131 of the equipment heat exchanger 10 flows downward, and further, as shown by the arrow β, the liquid film on the upper side wall in the tube 131. Evaporates by heat exchange with the part of the battery cell 21 that has been heated up to that point. Therefore, the liquid film on the side wall 137 in the tube 131 is thinned, and the area where the side wall 137 in the tube 131 is exposed to the gas-phase working fluid is increased. Thereby, the working fluid can be condensed in a wide range from the upper part to the lower part in the tube 131. Therefore, the working fluid evaporated at a relatively high temperature portion above the tube 131 is condensed at a relatively low temperature portion below the tube 131, and each battery cell 21 has a temperature distribution in the upper portion and the lower portion. It becomes smaller gradually. Moreover, since heat conduction also occurs in each battery cell 21, the temperature equalization of each battery cell 21 is promoted with the passage of time.
制御装置5は、加熱部61への通電停止から一定時間経過後、再び加熱部61への通電を開始する。このように、制御装置5は、加熱部61の駆動と停止を間欠的に繰り返しながら組電池2の暖機を行うことで、組電池2の温度分布の増大を抑制することが可能である。
The control device 5 starts energizing the heating unit 61 again after a certain time has elapsed since the energization of the heating unit 61 was stopped. In this way, the control device 5 can suppress an increase in the temperature distribution of the assembled battery 2 by warming up the assembled battery 2 while intermittently repeating driving and stopping of the heating unit 61.
次に、本実施形態の制御装置5が行う暖機制御処理について、図38のフローチャートを参照して説明する。
Next, the warm-up control process performed by the control device 5 of the present embodiment will be described with reference to the flowchart of FIG.
まず、ステップS10で制御装置5は、組電池2の暖機要求があるか否かを判定する。組電池2の暖機要求がある場合、制御装置5は処理をステップS20に移行する。
First, in step S10, the control device 5 determines whether or not there is a warm-up request for the assembled battery 2. When there is a warm-up request for the assembled battery 2, the control device 5 moves the process to step S20.
ステップS20で制御装置5は、加熱部61への通電を開始し、処理をステップS30に移行する。
In step S20, the control device 5 starts energizing the heating unit 61, and the process proceeds to step S30.
ステップS30で制御装置5は、組電池2の温度分布が所定の第1温度閾値以上であるか否かを判定する。第1温度閾値は、例えば実験等により設定され、制御装置5のメモリに予め記憶してある値である。
In step S30, the control device 5 determines whether or not the temperature distribution of the assembled battery 2 is equal to or greater than a predetermined first temperature threshold value. The first temperature threshold is a value that is set by, for example, experiments or the like and is stored in advance in the memory of the control device 5.
ここで、制御装置5が有する温度分布判定部110は、図33に示した各センサから入力される信号等に基づき、組電池2の温度分布の大きさを、次の方法により検出することが可能である。
Here, the temperature distribution determination unit 110 included in the control device 5 can detect the size of the temperature distribution of the assembled battery 2 by the following method based on signals input from the sensors shown in FIG. Is possible.
第1の方法として、制御装置5は、電池の温度を検出する複数の電池温度センサ101から入力される信号に基づいて、組電池2の温度分布の大きさを検出する。複数の電池温度センサ101は、電池セル21の上方部分と下方部分に設置することが好ましい。これにより、制御装置5は、電池セル21の上方部分と下方部分の温度分布の大きさを直接検出することが可能である。
As a first method, the control device 5 detects the size of the temperature distribution of the assembled battery 2 based on signals input from the plurality of battery temperature sensors 101 that detect the temperature of the battery. The plurality of battery temperature sensors 101 are preferably installed in the upper part and the lower part of the battery cell 21. Thereby, the control device 5 can directly detect the magnitude of the temperature distribution in the upper part and the lower part of the battery cell 21.
第2の方法として、制御装置5は、ヒータ温度センサ103と、作動流体温度センサ102から入力される信号に基づいて、組電池2の温度分布の大きさを検出する。ヒータ温度センサ103は、加熱部61の温度を検出するものである。作動流体温度センサ102は、機器温調装置1のサーモサイフォン回路を循環する作動流体の温度を検出するものである。サーモサイフォン回路を循環する作動流体の温度に対し、加熱部61の温度が高いほど、機器温調装置1による組電池2の加熱能力が大きいので、組電池2の温度分布が大きくなる。
As a second method, the control device 5 detects the size of the temperature distribution of the assembled battery 2 based on the signals input from the heater temperature sensor 103 and the working fluid temperature sensor 102. The heater temperature sensor 103 detects the temperature of the heating unit 61. The working fluid temperature sensor 102 detects the temperature of the working fluid circulating in the thermosiphon circuit of the device temperature control device 1. The higher the temperature of the heating unit 61 with respect to the temperature of the working fluid circulating in the thermosiphon circuit, the greater the heating capacity of the assembled battery 2 by the device temperature control device 1, and thus the temperature distribution of the assembled battery 2 becomes larger.
第3の方法として、制御装置5は、加熱部61が連続して作動している時間に基づいて、組電池2の温度分布の大きさを検出する。加熱部61が連続して作動している時間は、ヒータ通電時間検出部111により検出される加熱部61への連続通電オン時間である。加熱部61が連続して作動している時間が長いほど、組電池2の温度分布が大きくなる。
As a third method, the control device 5 detects the size of the temperature distribution of the assembled battery 2 based on the time during which the heating unit 61 is continuously operated. The time during which the heating unit 61 is continuously operated is the continuous energization on-time for the heating unit 61 detected by the heater energization time detection unit 111. The longer the time during which the heating unit 61 is operating continuously, the greater the temperature distribution of the assembled battery 2.
なお、制御装置5は、加熱部61が連続して作動を停止している時間に基づいて、組電池2の温度分布の大きさを検出することも可能である。加熱部61が連続して作動を停止している時間は、ヒータ通電時間検出部111により検出される加熱部61への連続通電オフ時間である。加熱部61が連続して作動を停止している時間が長いほど、組電池2の温度分布が小さくなる。
In addition, the control apparatus 5 can also detect the magnitude | size of the temperature distribution of the assembled battery 2 based on the time when the heating part 61 has stopped operation | movement continuously. The time during which the heating unit 61 continuously stops operating is the continuous energization off time to the heating unit 61 detected by the heater energization time detection unit 111. The longer the time during which the heating unit 61 is continuously stopped, the smaller the temperature distribution of the assembled battery 2.
第4の方法として、制御装置5は、加熱部61に供給される電力に基づいて、組電池2の温度分布の大きさを検出する。加熱部61に供給される電力は、ヒータ電力検出部112により検出される。加熱部61に供給される電力が大きいほど、機器温調装置1による組電池2の加熱能力が大きくなるので、組電池2の温度分布が大きくなる。一方、加熱部61に供給される電力が小さいほど、機器温調装置1による組電池2の加熱能力が小さくなるので、組電池2の温度分布が小さくなる。
As a fourth method, the control device 5 detects the size of the temperature distribution of the assembled battery 2 based on the power supplied to the heating unit 61. The power supplied to the heating unit 61 is detected by the heater power detection unit 112. As the electric power supplied to the heating unit 61 is larger, the heating capacity of the assembled battery 2 by the device temperature control device 1 becomes larger, and the temperature distribution of the assembled battery 2 becomes larger. On the other hand, the smaller the electric power supplied to the heating unit 61, the smaller the heating capacity of the assembled battery 2 by the device temperature control device 1, and thus the temperature distribution of the assembled battery 2 becomes smaller.
図38のステップS30で制御装置5は、組電池2の温度分布が所定の第1温度閾値以上であると判定すると、処理をステップS40に移行する。
38. When the control device 5 determines in step S30 of FIG. 38 that the temperature distribution of the assembled battery 2 is equal to or greater than a predetermined first temperature threshold, the process proceeds to step S40.
ステップS40で制御装置5は、加熱部61への通電を停止する。これにより、流体通路60から機器用熱交換器10への作動流体の流入が停止し、作動流体の流れが停止する。そのため、図37に示したように、機器用熱交換器10内の作動流体の液面FLが下がり、チューブ131内の側壁137の液膜が薄くなることで、チューブ131内の側壁137が気相の作動流体に露出する面積が広くなる。したがって、チューブ131内の上部から下部に亘り広い範囲で作動流体の凝縮が可能になり、各電池セル21は、上方部分と下方部分の温度分布が次第に小さくなる。また、各電池セル21内部での熱伝導も生じることから、時間の経過と共に各電池セル21の温度分布が小さくなる。
In step S40, the control device 5 stops energizing the heating unit 61. Thereby, the inflow of the working fluid from the fluid passage 60 to the equipment heat exchanger 10 is stopped, and the flow of the working fluid is stopped. For this reason, as shown in FIG. 37, the liquid level FL of the working fluid in the equipment heat exchanger 10 is lowered, and the liquid film on the side wall 137 in the tube 131 is thinned. The area exposed to the phase working fluid is increased. Therefore, the working fluid can be condensed in a wide range from the upper part to the lower part in the tube 131, and the temperature distribution of the upper part and the lower part of each battery cell 21 is gradually reduced. Moreover, since heat conduction also occurs inside each battery cell 21, the temperature distribution of each battery cell 21 becomes smaller with the passage of time.
ステップS40に続くステップS50で制御装置5は、組電池2の温度ばらつきが解消したか否かを判定する。具体的には、制御装置5は、組電池2の温度分布が所定の第2温度閾値以下か否かを判定する。第2温度閾値は、例えば実験等により設定され、制御装置5のメモリに予め記憶してある値である。制御装置5は、組電池2の温度分布が所定の第2温度閾値より大きいと判定すると、組電池2の温度ばらつきが解消していないとして、処理をステップS60に移行する。ステップS60で制御装置5は、加熱部61への通電を停止した状態を維持し、処理をステップS50に移行する。ステップS50とステップS60の処理は、組電池2の温度分布が所定の第2温度閾値以下になるまで繰り返し行われる。
In step S50 following step S40, the control device 5 determines whether or not the temperature variation of the assembled battery 2 has been eliminated. Specifically, the control device 5 determines whether or not the temperature distribution of the assembled battery 2 is equal to or less than a predetermined second temperature threshold value. The second temperature threshold is a value that is set, for example, by an experiment or the like and stored in advance in the memory of the control device 5. If the control device 5 determines that the temperature distribution of the assembled battery 2 is greater than the predetermined second temperature threshold, the process proceeds to step S60, assuming that the temperature variation of the assembled battery 2 has not been eliminated. In step S60, the control device 5 maintains a state where the energization to the heating unit 61 is stopped, and the process proceeds to step S50. Steps S50 and S60 are repeated until the temperature distribution of the assembled battery 2 is equal to or lower than a predetermined second temperature threshold.
一方、ステップS50で制御装置5は、組電池2の温度分布が所定の第2温度閾値以下であると判定すると、組電池2の温度ばらつきが解消したとして、処理をステップS70に移行する。ステップS70で制御装置5は、加熱部61への通電を再開し、処理を一旦終了する。そして、所定時間経過後、制御装置5は再びステップS10から上述した処理を繰り返す。
On the other hand, if the control device 5 determines in step S50 that the temperature distribution of the assembled battery 2 is equal to or lower than the predetermined second temperature threshold, the process proceeds to step S70 assuming that the temperature variation of the assembled battery 2 has been eliminated. In step S <b> 70, the control device 5 resumes energization to the heating unit 61 and ends the process once. And after predetermined time progress, the control apparatus 5 repeats the process mentioned above from step S10 again.
なお、上述したステップS10で組電池2の暖機要求がない場合、制御装置5は処理をステップS80に移行し、加熱部61への通電を停止した状態として、処理を一旦終了する。そして、所定時間経過後、再びステップS10から処理を繰り返す。
In addition, when there is no warming-up request | requirement of the assembled battery 2 by step S10 mentioned above, the control apparatus 5 transfers a process to step S80, makes the state which stopped the electricity supply to the heating part 61, and once complete | finishes a process. And after predetermined time progress, a process is repeated from step S10 again.
また、上述したステップS30で制御装置5は、組電池2の温度分布が所定の第1温度閾値より小さいと判定すると、処理をステップS90に移行し、加熱部61への通電を継続して、処理を一旦終了する。そして、所定時間経過後、再びステップS10から処理を繰り返す。
In addition, when the control device 5 determines in step S30 described above that the temperature distribution of the assembled battery 2 is smaller than the predetermined first temperature threshold, the process proceeds to step S90, and energization of the heating unit 61 is continued. The process is temporarily terminated. And after predetermined time progress, a process is repeated from step S10 again.
本実施形態の暖機制御処理による作用効果を、図39のグラフを参照して説明する。
The operation and effect of the warm-up control process of this embodiment will be described with reference to the graph of FIG.
図39では、本実施形態の暖機制御処理を行った場合の組電池2の温度分布の推移を実線TD1に示している。一方、本実施形態の暖機制御処理を行わず、暖機時に加熱部61への通電を継続してオンした場合の組電池2の温度分布の推移を実線TD2に示している。
In FIG. 39, the transition of the temperature distribution of the assembled battery 2 when the warm-up control process of the present embodiment is performed is shown by a solid line TD1. On the other hand, the solid line TD2 shows the transition of the temperature distribution of the assembled battery 2 when the warm-up control process of the present embodiment is not performed and the energization of the heating unit 61 is continuously turned on during warm-up.
実線TD2に示すように、本実施形態の暖機制御処理を行わず、暖機時に加熱部61への通電を継続してオンした場合、時刻t1から時刻t3にかけて組電池2の温度分布は時間経過とともに大きくなる。時刻t3で組電池2の温度分布は最大となっている。時刻t3で組電池2の暖機が完了すると、加熱部61への通電が停止されるので、組電池2の温度分布は時間経過とともに小さくなる。
As shown by the solid line TD2, when the warm-up control process of the present embodiment is not performed and the energization of the heating unit 61 is continuously turned on during warm-up, the temperature distribution of the assembled battery 2 is timed from time t1 to time t3. It grows with time. At time t3, the temperature distribution of the assembled battery 2 is maximum. When the warming-up of the assembled battery 2 is completed at time t3, the energization to the heating unit 61 is stopped, so that the temperature distribution of the assembled battery 2 decreases with time.
これに対し、実線TD1に示すように、本実施形態の暖機制御処理を行った場合、時刻t1からt2、t4からt5、t6からt7で加熱部61への通電が行われ、時刻t2からt4、t5からt6、t7以降で加熱部61への通電が停止されている。このように、暖機時に加熱部61への通電のオンオフを間欠的に繰り返した場合、組電池2の温度分布は一定の範囲内で推移する。したがって、制御装置5は、組電池2の暖機時に加熱部61の駆動と停止を間欠的に繰り返すことで、組電池2の温度分布の増大を抑制しつつ、組電池2を暖機することが可能である。その結果、この機器温調装置1は、組電池2が充放電を行う際に、電池セル21の中の温度の高い部分に電流集中が発生することを防ぎ、組電池2の劣化や破損を防ぐことができる。
On the other hand, as shown by the solid line TD1, when the warm-up control process of the present embodiment is performed, the heating unit 61 is energized from time t1 to t2, from t4 to t5, and from t6 to t7, and from time t2. Energization to the heating unit 61 is stopped after t4 and t5 to t6 and after t7. As described above, when the energization of the heating unit 61 is intermittently repeated during warm-up, the temperature distribution of the assembled battery 2 changes within a certain range. Therefore, the control device 5 warms up the assembled battery 2 while suppressing an increase in the temperature distribution of the assembled battery 2 by intermittently repeating driving and stopping of the heating unit 61 when the assembled battery 2 is warmed up. Is possible. As a result, when the assembled battery 2 performs charging / discharging, the device temperature control apparatus 1 prevents current concentration from occurring in a high temperature portion in the battery cell 21, and causes deterioration or breakage of the assembled battery 2. Can be prevented.
(第24実施形態)
第24実施形態について図40~図43を参照して説明する。本実施形態の機器温調装置1の構成は、第23実施形態で説明した構成と同じである。ただし、本実施形態は、上述した第23実施形態に対し、制御装置5による暖機制御処理が異なっている。上述した第23実施形態では、制御装置5は、組電池2の暖機時に、加熱部61への通電のオン、オフを間欠的に行う制御により、組電池2の温度分布の増大を抑制した。これに対し、本実施形態では、制御装置5は、組電池2の暖機時に、加熱部61の加熱能力の増大と低下を繰り返す制御により、組電池2の温度分布の増大を抑制するものである。 (24th Embodiment)
A twenty-fourth embodiment will be described with reference to FIGS. The configuration of the devicetemperature adjustment device 1 of the present embodiment is the same as the configuration described in the twenty-third embodiment. However, the present embodiment differs from the above-described twenty-third embodiment in the warm-up control process by the control device 5. In the twenty-third embodiment described above, the control device 5 suppresses an increase in the temperature distribution of the assembled battery 2 by controlling to intermittently turn on and off the energization of the heating unit 61 when the assembled battery 2 is warmed up. . On the other hand, in the present embodiment, the control device 5 suppresses an increase in the temperature distribution of the assembled battery 2 by controlling to repeatedly increase and decrease the heating capacity of the heating unit 61 when the assembled battery 2 is warmed up. is there.
第24実施形態について図40~図43を参照して説明する。本実施形態の機器温調装置1の構成は、第23実施形態で説明した構成と同じである。ただし、本実施形態は、上述した第23実施形態に対し、制御装置5による暖機制御処理が異なっている。上述した第23実施形態では、制御装置5は、組電池2の暖機時に、加熱部61への通電のオン、オフを間欠的に行う制御により、組電池2の温度分布の増大を抑制した。これに対し、本実施形態では、制御装置5は、組電池2の暖機時に、加熱部61の加熱能力の増大と低下を繰り返す制御により、組電池2の温度分布の増大を抑制するものである。 (24th Embodiment)
A twenty-fourth embodiment will be described with reference to FIGS. The configuration of the device
図41は、機器温調装置1が組電池2の暖機を行う前の状態を示している。制御装置5が加熱部61への通電を停止している。この状態で、機器用熱交換器10内の作動流体の液面FLは、電池セル21の高さ方向で比較的低い位置にある。
FIG. 41 shows a state before the device temperature control device 1 warms up the assembled battery 2. The control device 5 stops energizing the heating unit 61. In this state, the liquid level FL of the working fluid in the equipment heat exchanger 10 is at a relatively low position in the height direction of the battery cell 21.
次に、図42は、機器温調装置1が組電池2の暖機を行っているときの状態を示している。組電池2の暖機時、制御装置5は、加熱部61への通電を行い、加熱部61により作動流体を加熱する。組電池2の暖機時、機器用熱交換器10の複数のチューブ131内では、気相の作動流体が凝縮され、チューブ131内の側壁137を伝って重力方向下側へ流れる。そのため、チューブ131内の側壁137に形成される作動流体の液膜は、上方から下方に向かって次第に厚くなる。したがって、機器用熱交換器10内の上方では作動流体の液膜が薄いので電池セル21に対する作動流体の凝縮潜熱による加熱能力が大きい。これに対し、機器用熱交換器10の下方では作動流体の液膜が厚くなることから電池セル21に対する作動流体の凝縮潜熱による加熱能力が比較的小さくなる。また、機器用熱交換器10の下方では作動流体の液面FLが高くなり、その液面FLより下では電池セル21に対する作動流体の凝縮潜熱による加熱能力が非常に小さくなる。そのため、暖機時間の経過と共に、各電池セル21は、上方部分と下方部分の温度分布が次第に大きくなる。
Next, FIG. 42 shows a state where the device temperature control device 1 is warming up the assembled battery 2. When the assembled battery 2 is warmed up, the control device 5 energizes the heating unit 61 and heats the working fluid by the heating unit 61. When the assembled battery 2 is warmed up, the gas-phase working fluid is condensed in the plurality of tubes 131 of the equipment heat exchanger 10, flows along the side wall 137 in the tubes 131, and flows downward in the gravity direction. Therefore, the liquid film of the working fluid formed on the side wall 137 in the tube 131 gradually increases from the upper side to the lower side. Therefore, since the liquid film of the working fluid is thin above the apparatus heat exchanger 10, the heating capacity of the battery cell 21 by the condensation latent heat of the working fluid is large. On the other hand, since the liquid film of the working fluid is thicker below the equipment heat exchanger 10, the heating capacity of the battery cell 21 due to the latent heat of condensation of the working fluid becomes relatively small. In addition, the liquid level FL of the working fluid is high below the equipment heat exchanger 10, and the heating capacity of the battery cell 21 due to the latent heat of condensation of the working fluid is very small below the liquid level FL. Therefore, as the warm-up time elapses, the temperature distribution of the upper part and the lower part of each battery cell 21 gradually increases.
そこで、本実施形態では、組電池2の暖機開始から一定時間経過後、制御装置5は、加熱部61の加熱能力を低下させる制御を行う。これにより、流体通路60から機器用熱交換器10への作動流体の流入量が減少し、作動流体の流れが穏やかになる。そのため、図43に示すように、機器用熱交換器10内の作動流体の液面FLが下がる。また、機器用熱交換器10のチューブ131内の側壁137の液膜は薄くなるので、チューブ131内の上部と下部で作動流体の凝縮潜熱による加熱能力の差が縮小する。すなわち、チューブ131内の上部と下部で熱交換量の差が縮小する。また、各電池セル21内部での熱伝導も生じる。したがって、加熱能力の低下開始から時間の経過と共に、各電池セル21は、上方部分と下方部分の温度分布が次第に小さくなる。
Therefore, in the present embodiment, after a predetermined time has elapsed since the warm-up of the assembled battery 2 has started, the control device 5 performs control to reduce the heating capacity of the heating unit 61. Thereby, the inflow amount of the working fluid from the fluid passage 60 to the equipment heat exchanger 10 is reduced, and the flow of the working fluid becomes gentle. Therefore, as shown in FIG. 43, the liquid level FL of the working fluid in the equipment heat exchanger 10 is lowered. In addition, since the liquid film on the side wall 137 in the tube 131 of the equipment heat exchanger 10 becomes thin, the difference in heating ability due to the latent heat of condensation of the working fluid is reduced between the upper part and the lower part in the tube 131. That is, the difference in the amount of heat exchange between the upper part and the lower part in the tube 131 is reduced. In addition, heat conduction occurs in each battery cell 21. Therefore, with the passage of time from the start of the decrease in heating capacity, the temperature distribution of the upper part and the lower part of each battery cell 21 gradually decreases.
制御装置5は、加熱部61の加熱能力を減少してから一定時間経過後、再び加熱部61の加熱能力を増大する制御を行う。このように、制御装置5は、加熱部61の加熱能力の増大と低下を繰り返しながら組電池2の暖機を行うことで、組電池2の温度分布の増大を抑制することが可能である。
The control device 5 performs control to increase the heating capacity of the heating unit 61 again after a certain time has elapsed since the heating capacity of the heating unit 61 was decreased. Thus, the control device 5 can suppress an increase in the temperature distribution of the assembled battery 2 by warming up the assembled battery 2 while repeatedly increasing and decreasing the heating capacity of the heating unit 61.
本実施形態の制御装置5が行う暖機制御処理について、図40のフローチャートを参照して説明する。
The warm-up control process performed by the control device 5 of the present embodiment will be described with reference to the flowchart of FIG.
ステップS10からステップS30までの処理は、第23実施形態で説明した処理と同じである。
The processing from step S10 to step S30 is the same as the processing described in the twenty-third embodiment.
ステップS30で制御装置5は、組電池2の温度分布が所定の第1温度閾値以上であると判定すると、処理をステップS41に移行する。ステップS41で制御装置5は、加熱部61へ供給する電力量を低減し、加熱部61の加熱能力を減少させる。これにより、流体通路60から機器用熱交換器10への気相の作動流体の流入量が減少し、作動流体の流れが穏やかになる。そのため、図43に示すように、機器用熱交換器10内の作動流体の液面FLが下がる。また、機器用熱交換器10のチューブ131内の側壁137の液膜は薄くなり、チューブ131内の上部と下部の熱交換量の差が縮小する。また、各電池セル21内部での熱伝導も生じる。したがって、各電池セル21は、時間の経過と共に上方部分と下方部分の温度分布が次第に小さくなる。
When the control device 5 determines in step S30 that the temperature distribution of the assembled battery 2 is equal to or greater than the predetermined first temperature threshold, the process proceeds to step S41. In step S <b> 41, the control device 5 reduces the amount of power supplied to the heating unit 61 and decreases the heating capacity of the heating unit 61. Thereby, the inflow amount of the gaseous working fluid from the fluid passage 60 to the equipment heat exchanger 10 is reduced, and the flow of the working fluid becomes gentle. Therefore, as shown in FIG. 43, the liquid level FL of the working fluid in the equipment heat exchanger 10 is lowered. In addition, the liquid film on the side wall 137 in the tube 131 of the equipment heat exchanger 10 becomes thin, and the difference in the heat exchange amount between the upper part and the lower part in the tube 131 is reduced. In addition, heat conduction occurs in each battery cell 21. Accordingly, each battery cell 21 gradually decreases in temperature distribution in the upper part and the lower part as time passes.
ステップS41に続くステップS50で制御装置5は、組電池2の温度ばらつきが解消したか否かを判定する。制御装置5は、組電池2の温度ばらつきが解消していないと判定すると、処理をステップS61に移行する。ステップS61で制御装置5は、加熱部61の加熱能力を減少した状態を維持する。ステップS50とステップS61の処理は、組電池2の温度ばらつきが解消するまで繰り返し行われる。
In step S50 following step S41, the control device 5 determines whether or not the temperature variation of the assembled battery 2 has been eliminated. If the control device 5 determines that the temperature variation of the assembled battery 2 has not been eliminated, the process proceeds to step S61. In step S61, the control device 5 maintains a state where the heating capacity of the heating unit 61 is reduced. The process of step S50 and step S61 is repeatedly performed until the temperature variation of the assembled battery 2 is eliminated.
一方、ステップS50で制御装置5は、組電池2の温度ばらつきが解消したと判定すると、処理をステップS71に移行する。ステップS71で制御装置5は、加熱部61の加熱能力を再び増大する。具体的には、制御装置5は、加熱部61へ供給する電力量を増大する。ステップS71の後、処理は一旦終了する。そして、所定時間経過後、制御装置5は再びステップS10から処理を繰り返す。
On the other hand, if the control device 5 determines in step S50 that the temperature variation of the assembled battery 2 has been eliminated, the process proceeds to step S71. In step S71, the control device 5 increases the heating capacity of the heating unit 61 again. Specifically, the control device 5 increases the amount of power supplied to the heating unit 61. After step S71, the process is temporarily terminated. And after predetermined time progress, the control apparatus 5 repeats a process from step S10 again.
なお、上述したステップS30で制御装置5は、組電池2の温度分布が所定の第1温度閾値より小さいと判定すると、処理をステップS91に移行し、加熱部61の加熱能力を継続して維持する。そして、所定時間経過後、再びステップS10から処理を繰り返す。
In addition, if the control apparatus 5 determines with the temperature distribution of the assembled battery 2 being smaller than the predetermined 1st temperature threshold value by step S30 mentioned above, a process will transfer to step S91 and the heating capability of the heating part 61 will be maintained continuously. To do. And after predetermined time progress, a process is repeated from step S10 again.
本実施形態で説明した暖機制御処理は、上述した第23実施形態の暖機制御処理と同様の作用効果を奏することができる。
The warm-up control process described in this embodiment can achieve the same effects as the warm-up control process of the 23rd embodiment described above.

ここで、本実施形態では、制御装置5が有する温度分布判定部110は、図45に示した各センサから入力される信号等に基づき、組電池2の温度分布の大きさを、次の方法により検出することが可能である。
Here, in the present embodiment, the temperature distribution determination unit 110 included in the control device 5 determines the size of the temperature distribution of the assembled battery 2 based on a signal input from each sensor illustrated in FIG. Can be detected.
第1の方法として、制御装置5は、電池の温度を検出する複数の電池温度センサ101から入力される信号に基づいて、組電池2の温度分布の大きさを検出する。これにより、制御装置5は、電池セル21の上方部分と下方部分の温度分布の大きさを直接検出することが可能である。
As a first method, the control device 5 detects the size of the temperature distribution of the assembled battery 2 based on signals input from the plurality of battery temperature sensors 101 that detect the temperature of the battery. Thereby, the control device 5 can directly detect the magnitude of the temperature distribution in the upper part and the lower part of the battery cell 21.

As a second method, the control device 5 calculates the water temperature flowing through the water-working fluid heat exchanger 93 detected by the water-working fluid temperature sensor 105 and the temperature of the assembled battery 2 detected by the battery temperature sensor 101. Based on the difference, the size of the temperature distribution of the assembled battery 2 is detected. As the temperature of the water flowing through the water-working fluid heat exchanger 93 (that is, the temperature of the hot water) is higher than the temperature of the assembled battery 2, the heating capacity of the assembled battery 2 is larger, and the temperature distribution of the assembled battery 2 becomes larger.
第3の方法として、制御装置5は、水―作動流体熱交換器93を流れる水温と、組電池2の温度との差に加え、さらに、冷却水回路9を流れる水の流量に基づいて、組電池2の温度分布の大きさを検出する。水―作動流体熱交換器93を流れる水温は、水―作動流体温度センサ105により検出される。組電池2の温度は、電池温度センサ101により検出される。冷却水回路9を流れる水の流量は、水回路流量センサ106により検出される。冷却水回路9を流れる水の流量が多いほど、組電池2の加熱能力が大きいので、組電池2の温度分布が大きくなる。一方、冷却水回路9を流れる水の流量が少ないほど、組電池2の温度分布が小さくなる。
As a third method, the control device 5, in addition to the difference between the water temperature flowing through the water-working fluid heat exchanger 93 and the temperature of the assembled battery 2, further, based on the flow rate of water flowing through the cooling water circuit 9, The magnitude of the temperature distribution of the assembled battery 2 is detected. The water temperature flowing through the water-working fluid heat exchanger 93 is detected by a water-working fluid temperature sensor 105. The temperature of the assembled battery 2 is detected by the battery temperature sensor 101. The flow rate of water flowing through the cooling water circuit 9 is detected by the water circuit flow rate sensor 106. As the flow rate of water flowing through the cooling water circuit 9 increases, the heating capacity of the assembled battery 2 increases, so that the temperature distribution of the assembled battery 2 increases. On the other hand, the smaller the flow rate of the water flowing through the cooling water circuit 9, the smaller the temperature distribution of the assembled battery 2.
第4の方法として、制御装置5は、水―作動流体熱交換器93を流れる水温と、サーモサイフォン回路を循環する作動流体の温度との差に基づいて、組電池2の温度分布の大きさを検出する。水―作動流体熱交換器93を流れる水温は、制御装置5は、水―作動流体温度センサ105により検出される。サーモサイフォン回路を循環する作動流体の温度は、と、作動流体温度センサ102により検出される。サーモサイフォン回路を循環する作動流体の温度に対し、水―作動流体熱交換器93を流れる水温が高いほど、組電池2の加熱能力が大きいので、組電池2の温度分布が大きくなる。

Is detected. The temperature of the water flowing through the water-working fluid heat exchanger 93 is detected by the control device 5 by a water-working fluid temperature sensor 105. The temperature of the working fluid circulating through the thermosiphon circuit is detected by the working fluid temperature sensor 102. The higher the water temperature flowing through the water-working fluid heat exchanger 93 with respect to the temperature of the working fluid circulating in the thermosiphon circuit, the greater the heating capacity of the assembled battery 2, so the temperature distribution of the assembled battery 2 increases.
第5の方法として、制御装置5は、加熱部61が連続して作動している時間に基づいて、組電池2の温度分布の大きさを検出する。加熱部61が連続して作動している時間は、ウォータポンプ通電時間検出部115により検出されるウォータポンプ91への連続通電オン時間である。ウォータポンプ91が連続して作動している時間が長いほど、組電池2の温度分布が大きくなる。一方、ウォータポンプ91が連続して作動を停止している時間が長いほど、組電池2の温度分布が小さくなる。
As a fifth method, the control device 5 detects the size of the temperature distribution of the assembled battery 2 based on the time during which the heating unit 61 is continuously operating. The time during which the heating unit 61 is continuously operating is the continuous energization on time of the water pump 91 detected by the water pump energization time detection unit 115. The longer the time that the water pump 91 is operating continuously, the greater the temperature distribution of the assembled battery 2. On the other hand, the longer the time during which the water pump 91 is continuously stopped, the smaller the temperature distribution of the assembled battery 2 becomes.

In FIG. 46, the flow of the working fluid and the refrigerant when the devicetemperature control device 1 warms up the assembled battery 2 is indicated by solid and broken arrows. When the assembled battery 2 is warmed up, the control device 5 switches the first three-way valve 241 so that a part of the refrigerant flows from the indoor condenser 203 to the fourth branch part 214, and the second three-way valve 242 is connected to the second pipe by the refrigerant.

Further, a part of the refrigerant circulating in the heat pump cycle 201 is transferred from the first three-way valve 241 to the first pipe 231 → the third expansion valve 233 → the refrigerant-working fluid heat exchanger 200 → the second pipe 232 → the second three-way valve 242. → Flows through the sixth branch 216. The refrigerant flowing into the refrigerant-working fluid heat exchanger 200 from the first pipe 231 is depressurized by the third expansion valve 233 so that the temperature becomes an appropriate temperature for battery warm-up, and the fluid passage 60 of the device temperature adjustment device 1. The working fluid flowing through is heated. At this time, the working fluid flowing through the fluid passage 60 of the device temperature control apparatus 1 evaporates (that is, vaporizes) in the refrigerant-working fluid heat exchanger 200, flows upward, and passes from the upper connection portion 15 to the device heat exchanger 10. Supplied. Thereafter, the working fluid inside the equipment heat exchanger 10 dissipates heat to the battery cell 21 and condenses. Then, due to the head difference between the working fluid condensed in the equipment heat exchanger 10 and the working fluid in the fluid passage 60, the liquid-phase working fluid in the equipment heat exchanger 10 passes from the lower connection portion 16 through the fluid passage 60. Return to refrigerant-working fluid heat exchanger 200.
なお、HVACユニット250による車室内の暖房と組電池2の暖機を同時に行う場合、室内コンデンサ203に必要な温度と組電池2の暖機に必要な温度とに差があるため、第3膨張弁233の開度の調整が必要となる。一方、HVACユニット250による車室内の空調を行わず、組電池2の暖機のみを行う場合、コンプレッサ202の冷媒吐出量が組電池2の暖機に必要な冷媒量となるように調整し、第3膨張弁233を開いてもよい。
When heating the vehicle interior by the HVAC unit 250 and warming up the assembled battery 2 at the same time, there is a difference between the temperature required for the indoor condenser 203 and the temperature necessary for warming up the assembled battery 2, so that the third expansion Adjustment of the opening degree of the valve 233 is required. On the other hand, when only the warming up of the assembled battery 2 is performed without air conditioning the vehicle interior by the HVAC unit 250, the refrigerant discharge amount of the compressor 202 is adjusted to be the refrigerant amount necessary for warming up the assembled battery 2, The third expansion valve 233 may be opened.

本実施形態の制御装置5が行う暖機制御処理は、上述した第23および第24実施形態で説明した暖機制御処理と同じである。
The warm-up control process performed by the control device 5 of the present embodiment is the same as the warm-up control process described in the 23rd and 24th embodiments described above.
ここで、本実施形態では、制御装置5が有する温度分布判定部110は、図47に示した各センサから入力される信号等に基づき、組電池2の温度分布の大きさを、次の方法により検出することが可能である。
Here, in the present embodiment, the temperature distribution determination unit 110 included in the control device 5 determines the size of the temperature distribution of the assembled battery 2 based on the signal input from each sensor shown in FIG. Can be detected.
第1の方法として、制御装置5は、電池の温度を検出する複数の電池温度センサ101から入力される信号に基づいて、組電池2の温度分布の大きさを検出する。これにより、制御装置5は、電池セル21の上方部分と下方部分の温度分布の大きさを直接検出することが可能である。
As a first method, the control device 5 detects the size of the temperature distribution of the assembled battery 2 based on signals input from the plurality of battery temperature sensors 101 that detect the temperature of the battery. Thereby, the control device 5 can directly detect the magnitude of the temperature distribution in the upper part and the lower part of the battery cell 21.
第2の方法として、制御装置5は、冷媒温度センサ107により検出される冷媒―作動流体熱交換器200を流れる冷媒の温度と、電池温度センサ101により検出される組電池2の温度との差に基づいて、組電池2の温度分布の大きさを検出する。組電池2の温度に対し、冷媒―作動流体熱交換器200を流れる冷媒の温度が高いほど、組電池2の加熱能力が大きいので、組電池2の温度分布が大きくなる。
As a second method, the control device 5 determines the difference between the temperature of the refrigerant flowing through the refrigerant-working fluid heat exchanger 200 detected by the refrigerant temperature sensor 107 and the temperature of the assembled battery 2 detected by the battery temperature sensor 101. Based on the above, the magnitude of the temperature distribution of the assembled battery 2 is detected. The higher the temperature of the refrigerant flowing through the refrigerant-working fluid heat exchanger 200 with respect to the temperature of the assembled battery 2, the greater the heating capacity of the assembled battery 2, so the temperature distribution of the assembled battery 2 increases.
第3の方法として、制御装置5は、冷媒―作動流体熱交換器200を流れる冷媒の温度と、組電池2の温度との差に加え、さらに、ヒートポンプサイクルを流れる冷媒の流量に基づいて、組電池2の温度分布の大きさを検出する。冷媒―作動流体熱交換器200を流れる冷媒の温度は、冷媒温度センサ107により検出される。組電池2の温度は、電池温度センサ101により検出される。ヒートポンプサイクルを流れる冷媒の流量は、冷媒流量センサ108により検出される。ヒートポンプサイクルを流れる冷媒の流量が多いほど、組電池2の加熱能力が大きいので、組電池2の温度分布が大きくなる。一方、ヒートポンプサイクルを流れる冷媒の流量が少ないほど、組電池2の温度分布が小さくなる。
As a third method, the control device 5, based on the difference between the temperature of the refrigerant flowing through the refrigerant-working fluid heat exchanger 200 and the temperature of the assembled battery 2, and further based on the flow rate of the refrigerant flowing through the heat pump cycle, The magnitude of the temperature distribution of the assembled battery 2 is detected. The refrigerant temperature flowing through the refrigerant-working fluid heat exchanger 200 is detected by a refrigerant temperature sensor 107. The temperature of the assembled battery 2 is detected by the battery temperature sensor 101. The flow rate of the refrigerant flowing through the heat pump cycle is detected by the refrigerant flow rate sensor 108. As the flow rate of the refrigerant flowing through the heat pump cycle increases, the heating capacity of the assembled battery 2 increases, so that the temperature distribution of the assembled battery 2 increases. On the other hand, the smaller the flow rate of the refrigerant flowing through the heat pump cycle, the smaller the temperature distribution of the assembled battery 2.
第4の方法として、制御装置5は、冷媒―作動流体熱交換器200を流れる冷媒の温度と、サーモサイフォン回路を循環する作動流体の温度との差に基づいて、組電池2の温度分布の大きさを検出する。冷媒―作動流体熱交換器200を流れる冷媒の温度は、冷媒温度センサ107により検出される。サーモサイフォン回路を循環する作動流体の温度は、作動流体温度センサ102により検出される。サーモサイフォン回路を循環する作動流体の温度に対し、冷媒―作動流体熱交換器200を流れる冷媒の温度が高いほど、組電池2の加熱能力が大きいので、組電池2の温度分布が大きくなる。
As a fourth method, the control device 5 determines the temperature distribution of the assembled battery 2 based on the difference between the temperature of the refrigerant flowing through the refrigerant-working fluid heat exchanger 200 and the temperature of the working fluid circulating in the thermosiphon circuit. Detect the size. The refrigerant temperature flowing through the refrigerant-working fluid heat exchanger 200 is detected by a refrigerant temperature sensor 107. The temperature of the working fluid circulating through the thermosiphon circuit is detected by the working fluid temperature sensor 102. The higher the temperature of the refrigerant flowing through the refrigerant-working fluid heat exchanger 200 with respect to the temperature of the working fluid circulating in the thermosiphon circuit, the greater the heating capacity of the assembled battery 2, and thus the temperature distribution of the assembled battery 2 becomes larger.
第5の方法として、制御装置5は、加熱部61が連続して作動している時間に基づいて、組電池2の温度分布の大きさを検出する。加熱部61が連続して作動している時間は、コンプレッサ作動時間検出部116により検出されるコンプレッサ202の連続作動時間である。コンプレッサ202が連続して作動している時間が長いほど、組電池2の温度分布が大きくなる。一方、コンプレッサ202が連続して作動を停止している時間が長いほど、組電池2の温度分布が小さくなる。
As a fifth method, the control device 5 detects the size of the temperature distribution of the assembled battery 2 based on the time during which the heating unit 61 is continuously operating. The time during which the heating unit 61 operates continuously is the continuous operation time of the compressor 202 detected by the compressor operation time detection unit 116. The longer the time during which the compressor 202 is operating continuously, the greater the temperature distribution of the assembled battery 2. On the other hand, the longer the time during which the compressor 202 is continuously stopped, the smaller the temperature distribution of the battery pack 2 becomes.
第6の方法として、制御装置5は、コンプレッサ202の回転数に基づいて、組電池2の温度分布の大きさを検出する。コンプレッサ202の回転数は、コンプレッサ回転数検出部117により検出される。コンプレッサ202の回転数が高いほど、組電池2の温度分布が大きくなる。一方、コンプレッサ202の回転数が低いほど、組電池2の温度分布が小さくなる。
As a sixth method, the control device 5 detects the size of the temperature distribution of the assembled battery 2 based on the rotation speed of the compressor 202. The rotation speed of the compressor 202 is detected by the compressor rotation speed detector 117. The higher the rotation speed of the compressor 202, the larger the temperature distribution of the assembled battery 2. On the other hand, the lower the rotation speed of the compressor 202, the smaller the temperature distribution of the assembled battery 2.
第7の方法として、制御装置5は、冷媒―作動流体熱交換器200に流れる冷媒の流通時間に基づいて、組電池2の温度分布の大きさを検出する。冷媒―作動流体熱交換器200に流れる冷媒の流通時間は、冷媒流通時間検出部118により検出される。冷媒―作動流体熱交換器200に流れる冷媒の流通時間が長いほど、組電池2の温度分布が大きくなる。一方、冷媒―作動流体熱交換器200に流れる冷媒の流通遮断時間が長いほど、組電池2の温度分布が小さくなる。
As a seventh method, the control device 5 detects the magnitude of the temperature distribution of the assembled battery 2 based on the circulation time of the refrigerant flowing in the refrigerant-working fluid heat exchanger 200. The refrigerant circulation time flowing through the refrigerant-working fluid heat exchanger 200 is detected by the refrigerant circulation time detection unit 118. The longer the circulation time of the refrigerant flowing through the refrigerant-working fluid heat exchanger 200, the greater the temperature distribution of the assembled battery 2. On the other hand, the longer the distribution interruption time of the refrigerant flowing through the refrigerant-working fluid heat exchanger 200, the smaller the temperature distribution of the assembled battery 2.
なお、本実施形態の制御装置5が行う暖機制御処理において、組電池2の温度分布が大きくなったときに制御装置5が行う加熱部61の加熱能力の減少は、具体的には、コンプレッサ202の回転数減少などにより行われる。また、組電池2の温度分布が大きくなったときに制御装置5が行う加熱部61の作動停止は、具体的には、コンプレッサ202の作動停止などにより行われる。
Note that, in the warm-up control process performed by the control device 5 of the present embodiment, the decrease in the heating capacity of the heating unit 61 performed by the control device 5 when the temperature distribution of the assembled battery 2 becomes larger is specifically a compressor. This is performed by reducing the number of revolutions 202 or the like. Further, when the temperature distribution of the assembled battery 2 becomes large, the operation of the heating unit 61 performed by the control device 5 is specifically performed by stopping the operation of the compressor 202 or the like.
本実施形態も、上述した第23~第26実施形態と同様の作用効果を奏することができる。

Also good.
第28実施形態について図48および図49を参照して説明する。第28実施形態では、機器温調装置1は、機器用熱交換器10、上接続部15、下接続部16、流体通路60および熱供給部材100を備えている。機器用熱交換器10は、第21実施形態で説明したような、単一の容器17により構成されるものであってもよい。或いは、機器用熱交換器10は、第21実施形態以外の実施形態で説明したような上タンク11、下タンク12、および複数のチューブを有する熱交換部13などにより構成されるものであってもよい。 (Twenty-eighth embodiment)
A twenty-eighth embodiment will be described with reference to FIGS. 48 and 49. FIG. In the twenty-eighth embodiment, the device
機器用熱交換器10のうち重力方向上側となる位置に上接続部15が設けられ、機器用熱交換器10のうち重力方向下側となる位置に下接続部16が設けられている。上接続部15と下接続部16はいずれも、機器用熱交換器10に作動流体を流入させ、または、機器用熱交換器10から作動流体を流出させるための配管接続部である。
The upper connection part 15 is provided in the position which becomes the gravity direction upper side among the heat exchangers 10 for apparatuses, and the lower connection part 16 is provided in the position which becomes the gravity direction lower side among the heat exchangers 10 for apparatuses. Each of the upper connection portion 15 and the lower connection portion 16 is a pipe connection portion for allowing the working fluid to flow into the equipment heat exchanger 10 or for causing the working fluid to flow out from the equipment heat exchanger 10.
上接続部15と下接続部16とを連通させるように流体通路60が接続されている。流体通路60に設けられた熱供給部材100は、流体通路60を流れる作動流体に対し冷熱または温熱を選択的に供給可能な構成である。熱供給部材100として、後述する実施形態で説明するように、水―作動流体熱交換器、冷媒―作動流体熱交換器、またはペルチェ素子などを採用することが可能である。この熱供給部材100は、機器用熱交換器10の内側にある作動流体の液面FLの高さを跨ぐ高さ方向の位置で流体通路60に設けられている。そのため、熱供給部材100は、流体通路60を流れる気相の作動流体に対し冷熱を供給し、その作動流体を凝縮させることが可能である。また、熱供給部材100は、流体通路60を流れる液相の作動流体に対し温熱を供給し、その作動流体を蒸発させることも可能である。

次に、第28実施形態の機器温調装置1の作動について説明する。
Next, the operation of the device temperature control apparatus 1 according to the 28th embodiment will be described.
<冷却時の作動>
図48では、機器温調装置1が組電池を冷却するときの作動流体の流れを実線の矢印で示している。なお、図48および図49では組電池を図示していない。組電池の冷却時、熱供給部材100は、流体通路60を流れる作動流体に対し冷熱を供給する。これにより、流体通路60の作動流体が凝縮すると、流体通路60で凝縮した液相の作動流体と機器用熱交換器10内の液相の作動流体とのヘッド差により、流体通路60の液相の作動流体は下接続部16から機器用熱交換器10に流入する。機器用熱交換器10内の作動流体は、組電池を構成する各電池セル21から吸熱することにより蒸発する。この過程で電池セル21は、作動流体の蒸発潜熱により冷却される。その後、気相となった作動流体は上接続部15から流体通路60に流れる。 <Operation during cooling>
In FIG. 48, the flow of the working fluid when the devicetemperature control device 1 cools the assembled battery is indicated by solid-line arrows. 48 and 49 do not show the assembled battery. When the assembled battery is cooled, the heat supply member 100 supplies cold heat to the working fluid flowing through the fluid passage 60. Thus, when the working fluid in the fluid passage 60 is condensed, the liquid phase in the fluid passage 60 is caused by a head difference between the liquid working fluid condensed in the fluid passage 60 and the liquid working fluid in the equipment heat exchanger 10. The working fluid flows into the equipment heat exchanger 10 from the lower connecting portion 16. The working fluid in the equipment heat exchanger 10 evaporates by absorbing heat from each battery cell 21 constituting the assembled battery. In this process, the battery cell 21 is cooled by the latent heat of vaporization of the working fluid. Thereafter, the working fluid that has become a gas phase flows from the upper connecting portion 15 to the fluid passage 60.
図48では、機器温調装置1が組電池を冷却するときの作動流体の流れを実線の矢印で示している。なお、図48および図49では組電池を図示していない。組電池の冷却時、熱供給部材100は、流体通路60を流れる作動流体に対し冷熱を供給する。これにより、流体通路60の作動流体が凝縮すると、流体通路60で凝縮した液相の作動流体と機器用熱交換器10内の液相の作動流体とのヘッド差により、流体通路60の液相の作動流体は下接続部16から機器用熱交換器10に流入する。機器用熱交換器10内の作動流体は、組電池を構成する各電池セル21から吸熱することにより蒸発する。この過程で電池セル21は、作動流体の蒸発潜熱により冷却される。その後、気相となった作動流体は上接続部15から流体通路60に流れる。 <Operation during cooling>
In FIG. 48, the flow of the working fluid when the device

In FIG. 55, the flow of the working fluid and the cooling water when the devicetemperature control device 1 warms up the assembled battery 2 is indicated by solid and broken arrows. When the assembled battery 2 is warmed up, the control device 5 turns off the compressor 81 of the refrigeration cycle 8 and turns on the hot water heater 96 and the water pump 91. Accordingly, the high-temperature cooling water heated by the hot water heater 96 flows through the cooling water circuit 9 and is supplied to the water-working fluid heat exchange unit 1010 of the heat supply member 100.
