Description

Flow channel plate structure, refrigerant heat exchange module, thermal management system and vehicle

Technical Field

The present disclosure belongs to the field of thermal management technology, and in particular relates to a flow channel plate structure, a refrigerant heat exchange module, a thermal management system and a vehicle.

Background technique

In order to improve the comfort and riding experience of the occupants, the performance of the vehicle's thermal management system has been generally optimized. At present, the thermal management system may include a refrigerant heat exchange module with refrigerant as the heat exchange medium and a coolant heat exchange module with coolant as the heat exchange medium. The refrigerant heat exchange module may include an energy supply component, a heat exchange component, and a heat exchanger located between the energy supply component and the heat exchange component. The refrigerant of the energy supply component flows to the heat exchanger to exchange heat with the air or other modules and then flows into the heat exchange component, so that the heat exchange component can achieve front air conditioning refrigeration or rear air conditioning refrigeration. In this process, the circulation of the refrigerant is completely realized by the pipeline, which leads to a very complex pipeline design in the refrigerant heat exchange module. In addition, since the pipelines usually need to be connected by joints, and each joint needs a joint mounting seat for installation, the complex pipeline design also leads to a large number of joints and joint mounting seats, thereby increasing the cost and weight of the thermal management system and its space occupation in the whole vehicle.

Detailed ways

In order to more clearly understand the above-mentioned objectives, features and advantages of the present disclosure, the scheme of the present disclosure will be further described below. It should be noted that the embodiments of the present disclosure and the features in the embodiments can be combined with each other without conflict.

In the following description, many specific details are set forth to facilitate a full understanding of the present disclosure, but the present disclosure may also be implemented in other ways different from those described herein; it is obvious that the embodiments in the specification are only part of the embodiments of the present disclosure, rather than all of the embodiments.

1 is a schematic diagram of the structure of a refrigerant heat exchange module provided in some embodiments of the present application, FIG. 2 is a cross-sectional view of a first flow channel plate provided in some embodiments of the present application, and FIG. 3 is a cross-sectional view of a second flow channel plate provided in some embodiments of the present application.

As shown in Figures 1, 2 and 3, in the first aspect, an embodiment of the present application provides a flow channel plate structure, including a first flow channel plate 13 and a second flow channel plate 32, the first flow channel plate 13 is formed with a first flow channel 12, the inlet of the first flow channel 12 is connected to the outlet of the compressor 11 in the refrigerant heat exchange module of the thermal management system, and the outlet of the first flow channel 12 is connected to the inlet of the air heat exchanger 20 of the refrigerant heat exchange module; the second flow channel plate 32 is formed with a second flow channel 31, the inlet of the second flow channel 31 is connected to the outlet of the air heat exchanger 20, and the outlet of the second flow channel 31 is used to communicate with the inlet of the air-conditioning box of the thermal management system.

In the refrigerant heat exchange module, the compressor 11 is used to compress the low-temperature and low-pressure refrigerant into a high-temperature and high-pressure refrigerant. The compressor 11 is arranged at the inlet of the first flow channel 12, and its outlet is connected to the inlet of the first flow channel 12. Therefore, the high-temperature and high-pressure refrigerant flowing out of the compressor 11 outlet can flow into the first flow channel 12, and flow into the air heat exchanger 20 along the first flow channel 12. The air heat exchanger 20 can be used to exchange heat with the coolant heat exchange module or other modules of the air or thermal management system, so that the high-temperature and high-pressure refrigerant therein can release heat to the air or coolant heat exchange module, and the refrigerant after heat release flows into the air conditioner through the second flow channel 31 to realize the refrigeration function of the air conditioner. In this process, the first flow channel 12 in the first flow channel plate 13 and the second flow channel 31 in the second flow channel plate 32 replace most of the pipelines. It is only necessary to simply set pipelines at the outlets of the compressor 11, the air heat exchanger 20 and the second flow channel 31 to realize the circulation of the refrigerant, which can effectively simplify the pipeline design.

It is understandable that the air conditioning box may include a fan and an evaporator. The refrigerant in the second flow channel 31 may flow into the evaporator and absorb heat from the air around the evaporator in the evaporator. The cold air is then blown toward the passenger compartment through the fan to achieve cooling of the passenger compartment.

In the embodiment of the present application, the first flow channel plate 13 is formed with a first flow channel 12, the inlet of the first flow channel 12 is connected to the outlet of the compressor 11, and the outlet of the first flow channel 12 is connected to the inlet of the air heat exchanger 20 in the refrigerant heat exchange module, so that the fluid compressed by the compressor 11 can enter the first flow channel 12 and flow into the air heat exchanger 20 through the first flow channel 12. The second flow channel plate 32 is formed with a second flow channel 31, the inlet of the second flow channel 31 is connected to the outlet of the air heat exchanger 20, and the outlet of the second flow channel 31 is used to connect to the air conditioner of the thermal management system. The inlet of the box is connected, so after the fluid exchanges heat in the air heat exchanger 20, it can flow into the second flow channel 31, and flow to the air-conditioning box of the thermal management system through the outlet of the second flow channel 31 to realize the refrigeration function of the air-conditioning box. In this process, most of the pipelines in the refrigerant heat exchange module are replaced by the first flow channel 12 in the first flow channel plate 13 and the second flow channel 31 in the second flow channel plate 32, which can simplify the pipeline design in the refrigerant heat exchange module, reduce the number of joints and joint mounting seats when connecting the pipelines, and achieve the effect of reducing weight, cost and space occupancy.

Furthermore, in this embodiment, since there are usually refrigerant leakage points when the pipes are connected to the joints, this embodiment can also reduce the number of refrigerant leakage points by simplifying the pipe design and reducing the number of joints, thereby reducing refrigerant leakage in the refrigerant heat exchange module.

FIG. 4 is another schematic diagram of the structure of the refrigerant heat exchange module provided in some embodiments of the present application.

As shown in Figure 4, in some embodiments, the second flow channel 31 includes a first flow segment 311, a second flow segment 312 and a third flow segment 313, the inlet of the first flow segment 311 is connected to the outlet of the air heat exchanger 20, the inlet of the second flow segment 312 and the inlet of the third flow segment 313 are respectively connected to the outlet of the first flow segment 311, the outlet of the second flow segment 312 is connected to the inlet of the compressor 11, and the outlet of the third flow segment 313 is used to be connected to the inlet of the front air-conditioning box 40 and/or the inlet of the rear air-conditioning box 50 of the air-conditioning box, respectively, and the second flow segment 312 is sequentially provided with a first valve mounting position and a battery heat exchanger mounting position along the direction away from the first flow segment 311.

The first valve component mounting position is used to install the first valve component 33, and the battery heat exchanger mounting position is used to install the battery heat exchanger 34. The first valve component 33 and the battery heat exchanger 34 are sequentially arranged in the second flow section 312 in a direction away from the first flow section 311, and the battery heat exchanger 34 is used to exchange heat with the battery of the vehicle.

The second flow segment 312 and the third flow segment 313 are connected in parallel, and the two are respectively connected to the outlet of the first flow segment 311. Therefore, the refrigerant flowing out of the air heat exchanger 20 can pass through the first flow segment 311 and flow into the second flow segment 312 and the third flow segment 313 respectively. The refrigerant flowing into the third flow segment 313 can flow into the front air-conditioning box 40 and/or the rear air-conditioning box 50 respectively to realize cooling of the front passenger compartment and/or the rear passenger compartment.

The first valve member 33 and the battery heat exchanger 34 are sequentially arranged in the second flow section 312 in a direction away from the first flow section 311. Therefore, when the first valve member 33 is opened, the refrigerant can flow through the battery heat exchanger 34 and exchange heat with the battery of the vehicle in the battery heat exchanger 34 to cool the battery. It can be understood that when the battery does not need to be cooled, the first valve member 33 can be closed to prevent the refrigerant from flowing to the battery heat exchanger 34.

In this embodiment, by arranging the first valve component 33 and the battery heat exchanger 34 in the second flow section 312 and exchanging heat with the battery through the battery heat exchanger 34, compared with separately arranging pipelines to conduct the refrigerant to the battery for heat exchange, the pipeline design can be further simplified and the number of joints and joint mounting seats can be reduced.

It can be understood that the battery heat exchanger 34 can indirectly exchange heat with the battery of the vehicle through the cooling heat exchange module in the thermal management system. Specifically, a part of the coolant heat exchange module is arranged between the battery heat exchanger 34 and the battery, and the coolant heat exchange module exchanges heat with the battery heat exchanger 34 and the battery at the same time, thereby realizing heat transfer between the battery heat exchanger 34 and the battery.

Optionally, the first valve member 33 may be configured as a throttle valve, and by adjusting the size of the valve opening of the first valve member 33, the flow rate of the refrigerant flowing into the second flow segment 312 may be controlled, thereby adjusting the cooling effect on the battery. Furthermore, by adjusting the flow rate of the refrigerant flowing into the second flow segment 312, the flow rate of the refrigerant flowing into the third flow segment 313 may also be indirectly adjusted, thereby adjusting the cooling effect on the front air conditioner and/or the rear air conditioner.

Optionally, the second flow section 312 may also be provided with a first sensor installation position, the first sensor installation position is used to install a first sensor, and the first sensor is used to detect the pressure and/or temperature of the refrigerant in the second flow section 312. Further, the first sensor may be provided at the outlet of the battery heat exchanger 34 to detect the pressure and/or temperature of the refrigerant flowing out of the battery heat exchanger 34. In addition, the first sensor may be provided close to the outlet of the battery heat exchanger 34 to improve the reliability of the detection.

Please continue to refer to Figure 4. In some embodiments, the third flow segment 313 includes a first sub-segment 314 and a second sub-segment 315 respectively connected to the outlet of the first flow segment 311. The outlet of the first sub-segment 314 is used to connect to the inlet of the front air-conditioning box 40, and the outlet of the second sub-segment 315 is used to connect to the inlet of the rear air-conditioning box 50, thereby realizing front air-conditioning cooling and rear air-conditioning cooling respectively.

It is understandable that, in the refrigerant heat exchange module, by controlling the on-off of the first valve member 33, at least one of the front air conditioning refrigeration function, the air conditioning refrigeration function and the battery cooling function can be realized, and the operating state of the refrigerant heat exchange module can be flexibly adjusted. Moreover, in this embodiment, by setting the third flow segment 313 to include the first sub-segment 314 and the second sub-segment 315, the refrigerant is transported to the front air conditioning box 40 through the first sub-segment 314, and the refrigerant is transported to the rear air conditioning box 50 through the second sub-segment 315, which can avoid the refrigerant flowing into the front air conditioning box 40 and the refrigerant flowing into the rear air conditioning box 50 from affecting each other, thereby affecting the refrigeration effect of the front air conditioning box 40 and/or the rear air conditioning box 50.

Optionally, a second valve installation position may be provided in the first subsection 314, and the second valve installation position is used to install a second valve, and the second valve may be configured as a throttle valve, so that by adjusting the valve port size of the second valve, the flow of the refrigerant flowing into the first subsection 314 and the second subsection 315 can be reasonably distributed, thereby adjusting the cooling effect of the front air conditioner and/or the rear air conditioner. It is understandable that the second valve may also be provided at the front air conditioner box 40, so as to avoid affecting the volume of the second flow channel plate 32.

And/or, the first flow section 311 is provided with a third valve component installation position, and the third valve component installation position is used to install a third valve component 36 that is unidirectionally conductive along the direction away from the outlet of the air heat exchanger 20, thereby preventing the refrigerant in the first sub-section 314, the second sub-section 315 and the third flow section 313 from flowing back to the first flow section 311 and affecting the normal operation of the refrigerant heat exchange module.

Please continue to refer to Figure 3. In some embodiments, the first flow segment 311, the second flow segment 312 and the third flow segment 313 extend along the edge of the second flow channel plate 32 respectively. The first flow segment 311 includes an inlet end and outlet ends located on both sides of the inlet end. The second flow segment 312 is connected to one outlet end, and the first sub-segment 314 and the second sub-segment 315 of the third flow segment 313 are respectively connected to the other outlet end, so that the positions of the first flow segment 311, the second flow segment 312 and the third flow segment 313 in the second flow channel plate 32 are reasonably set to improve the space utilization of the second flow channel plate 32. In addition, the first flow segment 311, the second flow segment 312 and the third flow segment 313 extend along the edge of the second flow channel plate 32 respectively, which can facilitate the installation of corresponding valve components and heat exchangers in the first flow segment 311, the second flow segment 312 and the third flow segment 313 to reduce the difficulty of assembly. At the same time, the plane where the first sub-segment 314 is located overlaps with the plane where the first flow segment 311, the second sub-segment 315 and the second flow segment 312 are located, so that the size of the plane where the first flow segment 311, the second sub-segment 315 and the second flow segment 312 are located can be reduced, and the overall volume of the second flow channel plate 32 can be reduced.

It can be understood that the first valve component 33, the battery heat exchanger 34, the second valve component and the third valve component 36 are assembled on the outer side of the second flow channel plate 32 and are arranged corresponding to the positions of the flow sections in which they are located. The actual positions of the first valve component 33, the battery heat exchanger 34, the second valve component and the third valve component 36 are not limited in this embodiment.

FIG. 5 is another schematic structural diagram of the refrigerant heat exchange module provided in some embodiments of the present application.

As shown in Figure 5, in some embodiments, the first flow channel 12 includes a fourth flow segment 121, a fifth flow segment 122 and a sixth flow segment 123, the inlet of the fourth flow segment 121 is connected to the outlet of the compressor 11, the fourth flow segment 121 is provided with a condenser installation position, the condenser installation position is used to install the condenser 14 that exchanges heat with the coolant heat exchange module of the thermal management system, the fifth flow segment 122 and the sixth flow segment 123 are respectively connected to the outlet of the fourth flow segment 121, the outlet of the fifth flow segment 122 is connected to the inlet of the air heat exchanger 20, the outlet of the sixth flow segment 123 is connected to the inlet of the second flow segment 312 and/or the third flow segment 313, the fifth flow segment 122 is provided with a fourth valve component installation position, and the sixth flow segment 123 is provided with a fifth valve component installation position.

The fourth valve component installation position is used to install the fourth valve component 15, and the fifth valve component installation position is used to install the fifth valve component 16. The fourth valve component 15 and the fifth valve component 16 are used to control the on-off of the fifth flow section 122 and the sixth flow section 123 respectively. It can be understood that when the fourth valve member 15 is opened and the fifth valve member 16 is closed, the condenser 14 can be controlled to be closed, and the refrigerant flowing out from the outlet of the compressor 11 can flow through the fourth flow segment 121 and the fifth flow segment 122 in sequence, and flow into the air heat exchanger 20 to release heat, and then flow from the outlet of the air heat exchanger 20 to the first flow segment 311, and flow into the second flow segment 312 and/or the third flow segment 313 through the first flow segment 311, so as to realize at least one of the front air conditioning refrigeration function, the rear air conditioning refrigeration function and the battery cooling function; or, at this time, the condenser 14 can also be controlled to be opened, so that the refrigerant flowing out of the compressor 11 exchanges heat with the coolant heat exchange module through the condenser 14 at the fourth flow segment 121, so as to release heat to the coolant heat exchange module, so as to facilitate the coolant heat exchange module to realize the heating function of the front air conditioning and/or the rear air conditioning, and then the refrigerant after releasing heat flows through the fifth flow segment 122 and the air heat exchanger 20 in sequence and flows back to the inlet of the compressor 11. It can be understood that the front air-conditioning box 40 and/or the rear air-conditioning box 50 may also include an air condenser, which is connected to the coolant heat exchange module. Therefore, after the coolant in the coolant heat exchange module exchanges heat with the refrigerant in the refrigerant heat exchange module and absorbs heat from the refrigerant, the coolant can flow into the air condenser and release heat to the surrounding air at the air condenser. The air around the air condenser can be converted into hot air, and then the hot air is driven by a fan to flow to the passenger compartment, thereby achieving heating of the passenger compartment.

When the fourth valve member 15 is closed and the fifth valve member 16 is opened, the condenser 14 can be controlled to open, so that the refrigerant flowing out of the compressor 11 exchanges heat with the coolant heat exchange module through the condenser 14 at the fourth flow segment 121, and releases heat to the coolant heat exchange module. Subsequently, the refrigerant after heat release can flow to the second flow segment 312 and/or the third flow segment 313 through the sixth flow segment 123. When the refrigerant flows into the second flow segment 312, the refrigerant can exchange heat with the battery through the battery heat exchanger 34 in the second flow segment 312, absorb the heat generated during the operation of the battery, and realize the utilization of the battery heat. In addition, in the battery The refrigerant after absorbing heat at the pool heat exchanger 34 can flow back to the compressor 11; and/or, when the refrigerant flows into the third flow segment 313, the refrigerant can flow into the front air-conditioning box 40 and/or the rear air-conditioning box 50 through the third flow segment 313, and exchange heat with the surrounding air at the evaporator in the front air-conditioning box 40 and/or the rear air-conditioning box 50, absorb heat in the air around the evaporator, convert the surrounding air into cold air, and the water vapor in the air can release heat and condense into liquid, thereby reducing the water vapor content in the air, and then, the dehumidified cold air is driven by a fan to flow to the passenger compartment, so that the passenger compartment can be dehumidified.

Optionally, in the front air conditioning box 40 and/or the rear air conditioning box 50, the evaporator can be located upstream of the air condenser along the air outlet direction. When the fourth valve member 15 and the fifth valve member 16 can also be opened at the same time, the condenser 14 can be opened, so that the refrigerant flowing out of the compressor 11 exchanges heat with the coolant heat exchange module through the condenser 14 at the fourth flow segment 121, and releases heat to the coolant heat exchange module. After absorbing the heat in the refrigerant, the coolant in the coolant heat exchange module can flow into the air condenser in the front air conditioning box 40 and/or the rear air conditioning box 50 and release heat to the surroundings. At the same time, the refrigerant flowing out of the condenser 14 can flow into the fifth flow segment 122 and the sixth flow segment 123 at the same time, and flow into the fifth flow segment 12 The refrigerant in the sixth flow segment 123 can flow back to the compressor 11 through the air heat exchanger 20, and the refrigerant flowing into the sixth flow segment 123 can flow to the evaporator in the front air-conditioning box 40 and/or the rear air-conditioning box 50 through the third flow segment 313 to dehumidify the air around the evaporator. Subsequently, the dehumidified cold air can flow through the air condenser driven by the fan, absorb part of the heat in the coolant at the air condenser, and then flow to the passenger compartment, thereby avoiding the temperature of the air flowing into the passenger compartment being too low. This mode can be used to dehumidify the passenger compartment in winter to improve the comfort of the passenger compartment.

It can be understood that when the fourth valve component 15 and the fifth valve component 16 are opened at the same time, the refrigerant heat exchange module can also realize a combination of other functions. For example, the refrigerant heat exchange module can simultaneously realize the battery cooling function and the dehumidification function of the front and rear air conditioners, or the refrigerant heat exchange module can simultaneously realize the refrigeration function of the front and rear air conditioners and the dehumidification function of the front and rear air conditioners, or the refrigerant heat exchange can also simultaneously realize the refrigeration function of the front and rear air conditioners and the battery heat recovery function. The realization of various functions of the refrigerant heat exchange module can be flexibly adjusted as needed during the application process, and it is only necessary to avoid the occurrence of contradictory situations such as realizing the refrigeration function and heating function of the front and rear air conditioners at the same time.

Optionally, the fourth valve component 15 can be configured as a throttle valve. When the fourth valve component 15 and the fifth valve component 16 are opened at the same time, the flow rate of the refrigerant flowing into the fifth flow segment 122 and the sixth flow segment 123 can be reasonably adjusted by controlling the valve port size of the fourth valve component 15.

In this embodiment, the state of the refrigerant heat exchange module can be flexibly adjusted by controlling the state of the fourth valve member 15 and the fifth valve member 16 to realize different functions of the refrigerant heat exchange module. At the same time, by arranging the condenser 14 in the first flow channel 12 and reasonably designing the flow paths of the first flow channel 12 and the second flow channel 31 to realize the above functions, compared with realizing the above functions through pipeline design, the pipeline design can be further simplified and the number of joints and joint mounting seats can be reduced.

Optionally, the fourth flow segment 121 may be provided with a second sensor installation position, the second sensor installation position is used to install a second sensor, and the second sensor is used to detect the pressure and/or temperature of the refrigerant in the fourth flow segment 121. It is understandable that the second sensor can be arranged at the outlet of the condenser 14 to detect the pressure and/or temperature of the refrigerant after the heat is released from the condenser 14. In addition, the second sensor is arranged close to the outlet of the condenser 14, which can improve the detection reliability of the second sensor.

FIG6 is a cross-sectional view of the first flow channel plate provided in some embodiments of the present application at another viewing angle.

As shown in Figures 2 and 6, in some embodiments, the fourth flow segment 121 includes a third sub-segment 124 and a fourth sub-segment 125 that are interconnected, the inlet of the third sub-segment 124 is connected to the outlet of the compressor 11, the condenser mounting position is set in the third sub-segment 124, the fourth sub-segment 125 is bent relative to the third sub-segment 124, the fourth sub-segment 125, the fifth flow segment 122 and the sixth flow segment 123 are located in the same plane, and are all overlapped with the third sub-segment 124, the fifth flow segment 122 and the sixth flow segment 123 are arranged side by side, and are respectively connected to the fourth sub-segment 125, so that by reasonably setting the positions of each flow segment in the first flow channel plate 13, the space utilization rate in the first flow channel plate 13 can be improved, and the difficulty of installing the condenser 14 and each valve to the corresponding mounting position can be reduced.

It can be understood that, since the fourth sub-segment 125, the fifth flow segment 122 and the sixth flow segment 123 are located in the same plane and are all arranged to overlap with the third sub-segment 124, when the condenser 14 is installed in the condenser installation position, the condenser 14 is respectively located in two different planes from the fourth sub-segment 125, the fifth flow segment 122 and the sixth flow segment 123. In addition, the positions of the fourth valve member 15 and the fifth valve member 16 can be reasonably set according to the positions of the fifth flow segment 122 and the sixth flow segment 123, which is not limited in this embodiment.

Optionally, the condenser 14 includes a plurality of conductive layers stacked in sequence along the overlapping direction, the plurality of conductive layers form a third sub-segment 124 for circulating refrigerant, the inlets of the plurality of conductive layers are all connected to the outlet of the compressor 11, and the outlets of the plurality of conductive layers are all connected to the fourth sub-segment 125, so as to guide the refrigerant flowing out of the compressor 11 to the fourth sub-segment 125. It can be understood that the overlapping direction refers to the direction in which the plane where the fourth sub-segment 125, the fifth flow segment 122 and the sixth flow segment 123 are located overlaps with the third sub-segment 124.

FIG. 7 is another schematic structural diagram of the refrigerant heat exchange module provided in some embodiments of the present application.

As shown in Figure 7, in some embodiments, the second flow channel 31 also includes a seventh flow segment 316, the inlet of the seventh flow segment 316 is connected to the outlet of the air heat exchanger 20, and the outlet of the seventh flow segment 316 is connected to the inlet of the compressor 11. Therefore, by controlling the condenser 14 to open, the refrigerant flowing out of the compressor 11 exchanges heat with the coolant heat exchange module through the condenser 14 in the first flow channel 12, releases heat to the coolant heat exchange module, and releases heat to the front air conditioner and/or the rear air conditioner through the coolant heat exchange module, thereby realizing the heating function of the front air conditioner and/or the rear air conditioner. Subsequently, the refrigerant after heat release flows into the air heat exchanger 20 to exchange heat with the air or other heat exchange modules, and after heat exchange, flows back to the inlet of the compressor 11 through the seventh flow segment 316, thereby realizing the heating cycle of the refrigerant heat exchange module. It can be understood that, during this process, the fifth valve component 16 is in a closed state, and the fourth valve component 15 is in a throttling state, so that the refrigerant in the condenser 14 can flow into the air heat exchanger 20, and the third valve component 36, the first valve component 33 and the second valve component are all in a closed state, thereby preventing the refrigerant flowing out of the air heat exchanger 20 from flowing into the first flow section 311, the second flow section 312 and the third flow section 313.

In addition, a sixth valve component installation position is provided in the seventh flow segment, and the sixth valve component installation position is used to install the sixth valve component 37, so as to control the opening or closing of the seventh flow segment 316 by controlling the opening or closing of the sixth valve component 37.

In some embodiments, the second flow channel 31 also includes an eighth flow segment 317, the inlet of the eighth flow segment 317 is connected to the outlet of the compressor 11, the outlet of the eighth flow segment 317 is connected to the second flow segment 312, and the outlet of the eighth flow segment 317 is located between the first valve mounting position and the battery heat exchanger mounting position.

Specifically, the refrigerant flowing out from the outlet of the compressor 11 can flow into the first flow channel 12 and the eighth flow segment 317 respectively, and flow into the second flow segment 312 through the eighth flow segment 317, and release heat to the coolant heat exchange module between the battery heat exchanger 34 and the battery in the second flow segment 312 through the battery heat exchanger 34. After absorbing heat, the coolant in the coolant heat exchange module at the battery heat exchanger 34 can flow to the condenser 14, and release heat to the front air-conditioning box 40 and/or the rear air-conditioning box 50 at the condenser 14, so as to realize the heating function of the front air-conditioning and/or rear air-conditioning. At this time, the refrigerant flowing into the first flow channel 12 can release heat to the coolant in the coolant heat exchange module at the condenser 14 to further improve the heating effect of the front air-conditioning and/or rear air-conditioning, and the refrigerant after releasing heat at the condenser 14 can flow through the fifth flow segment 122, the air heat exchanger 20 and the seventh flow segment 316 in sequence, and flow back to the inlet of the compressor 11.

It is understandable that a valve may be provided in the eighth flow segment 317 to control the on-off of the eighth flow segment 317 .

Please continue to refer to Figure 3. In some embodiments, the seventh flow segment 316 is located between the inlet of the first flow segment 311 and the outlet of the second flow segment 312. The inlet of the seventh flow segment 316 merges with the inlet of the first flow segment 311, and the outlet of the seventh flow segment 316 merges with the outlet of the second flow segment 312. The first flow segment 311, the second flow segment 312 and the third flow segment 313 are respectively located on three adjacent sides of the seventh flow segment 316. The first flow segment 311, the seventh flow segment 316 and the second flow segment 312 are arranged around the eighth flow segment 317, so as to improve the space utilization rate of the second flow channel plate 32 by reasonably setting the positions of the seventh flow segment 316 and the eighth flow segment 317 in the second flow channel plate 32.

In the second aspect, the embodiment of the present application further provides a refrigerant heat exchange module, including a compressor 11, an air heat exchanger 20, and a flow channel plate structure of any of the above items. The refrigerant heat exchange module provided by the embodiment of the present application has the technical effect of the technical solution of the flow channel plate structure in any of the above embodiments, and the explanation of the structures and terms that are the same or corresponding to the above embodiments will not be repeated here.

Please continue to refer to Figure 7. In some embodiments, the refrigerant heat exchange module also includes a gas-liquid separator 60, the outlet of the gas-liquid separator 60 is connected to the inlet of the compressor 11, and the inlet of the gas-liquid separator 60 is respectively connected to the outlet of the seventh flow segment 316, the outlet of the second flow segment 312, and the outlet of the front air-conditioning box 40 and/or the rear air-conditioning box 50. Therefore, the refrigerant after heat exchange in the front air-conditioning box 40 and/or the rear air-conditioning box 50 can flow back to the compressor 11 through the gas-liquid separator 60, so as to realize the recycling of the refrigerant flowing into the front air-conditioning box 40 and/or the rear air-conditioning box 50, and the refrigerant flowing out of the seventh flow segment 316, the refrigerant flowing out of the second flow segment 312, and the refrigerant flowing out of the front air-conditioning box 40 and/or the rear air-conditioning box 50 is separated into gas and liquid through the gas-liquid separator 60 to prevent liquid refrigerant from flowing into the compressor 11 and affecting the normal operation of the compressor 11.

The gas-liquid separator 60 is used to separate the liquid refrigerant from the gaseous refrigerant, so that the gaseous refrigerant flows back to the compressor 11 , and the liquid refrigerant is stored in the gas-liquid separator 60 , thereby preventing the liquid refrigerant from flowing into the compressor 11 and affecting the normal operation of the compressor 11 .

It can be understood that, in this embodiment, the inlet of the gas-liquid separator 60 is connected to the outlet of the seventh flow segment 316, and the outlet of the gas-liquid separator 60 is connected to the inlet of the compressor 11. When the refrigerant flowing out of the compressor 11 releases heat to the coolant heat exchange module at the condenser 14 to realize the heating function of the front air conditioner and/or the rear air conditioner through the coolant heat exchange module, the refrigerant after heat release can flow into the air heat exchanger 20 for heat exchange. Subsequently, the sixth valve member 37 is opened, and the first valve member 33, the second valve member and the third valve member 36 are closed, so that the refrigerant flowing through the air heat exchanger 20 can flow into the seventh flow segment 316 and flow into the gas-liquid separator 60 from the outlet of the seventh flow segment 316. The refrigerant is separated into gas and liquid in the gas-liquid separator 60, so that the gaseous refrigerant therein flows back to the compressor 11, while the liquid refrigerant is stored in the gas-liquid separator 60, thereby preventing the liquid refrigerant from flowing into the compressor 11 and affecting the normal operation of the compressor 11.

Moreover, in the present embodiment, the inlet of the gas-liquid separator 60 is also connected to the outlet of the second flow segment 312. Therefore, when the battery cooling function of the refrigerant heat exchange module is turned on, the refrigerant flowing out from the outlet of the battery heat exchanger 34 can flow into the gas-liquid separator 60 after passing through the third flow segment 313. The refrigerant is separated into gas and liquid in the gas-liquid separator 60, so that the gaseous refrigerant therein flows back to the inlet of the compressor 11, while the liquid refrigerant is stored in the gas-liquid separator 60, thereby preventing the liquid refrigerant from flowing into the compressor 11 and affecting the normal operation of the compressor 11.

And/or, the refrigerant heat exchange module also includes a seventh valve component 38, which is used to be arranged between the outlet of the rear air-conditioning box 50 and the inlet of the gas-liquid separator 60. The seventh valve component 38 is configured to be unidirectionally conductive from the rear air-conditioning box 50 to the gas-liquid separator 60. Therefore, when the rear air-conditioning refrigeration function of the refrigerant heat exchange module is turned off, the seventh valve component 38 can prevent the refrigerant at the gas-liquid separator 60 from flowing back to the rear air-conditioning box 50, thereby preventing the refluxed refrigerant from being blocked in the rear air-conditioning box 50 or between the gas-liquid separator 60 and the rear air-conditioning box 50, so as to ensure the normal realization of the rear air-conditioning refrigeration function of the refrigerant heat exchange module.

It can be understood that when the rear air-conditioning cooling function of the refrigerant heat exchange module is turned off, the front air-conditioning cooling function and the battery cooling function of the refrigerant heat exchange module can be in the turned-on state, that is, the refrigerant in the gas-liquid separator 60 at this time can come from the front air-conditioning box 40 or the third flow section 313.

In a third aspect, an embodiment of the present application provides a thermal management system, including an air conditioning box and a refrigerant heat exchange module as described above, wherein the outlet of the second flow channel 31 is connected to the inlet of the air conditioning box.

In some embodiments, the thermal management system further includes a coolant heat exchange module, which includes a mounting base and a cooling heat exchange module body disposed on the mounting base, and the first flow channel plate 13 and the second flow channel plate 32 are respectively disposed on the mounting base.

The coolant heat exchange module can be configured to be able to exchange heat with the air and/or electrical devices in the vehicle to absorb heat from the air and/or electrical devices. At the same time, the coolant heat exchange module can also exchange heat with the refrigerant heat exchange module through the condenser 14 to absorb heat from the refrigerant in the refrigerant heat exchange module, so that the coolant in the coolant heat exchange module can be conducted to the front air-conditioning box 40 and/or the rear air-conditioning box 50 so that the coolant can release heat in the front air-conditioning box 40 and/or the rear air-conditioning box 50 to convert the air in the front air-conditioning box 40 and/or the rear air-conditioning box 50 into hot air, thereby achieving heating of the passenger compartment.

In this embodiment, by integrating the first flow channel plate 13 and the second flow channel plate 32 of the refrigerant heat exchange module on the mounting base of the coolant heat exchange module, the integration level of the thermal management system can be improved, the piping design in the thermal management system can be simplified, and the weight and cost can be reduced as well as the space occupied by the thermal management system in the vehicle can be reduced. In addition, by integrating the refrigerant heat exchange module and the coolant heat exchange module together, the controller can also control the refrigerant heat exchange module and the coolant heat exchange module more conveniently, thereby improving the control efficiency.
