Fig. 4 is another schematic structural view of a refrigerant heat exchange module according to some embodiments of the application.

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

The second flow section 312 is connected in parallel with the third flow section 313 and both are respectively communicated with the outlets of the first flow section 311, so that the refrigerant flowing out of the air heat exchanger 20 can pass through the first flow section 311 and respectively flow into the second flow section 312 and the third flow section 313, and the refrigerant flowing into the third flow section 313 can respectively flow into the front air conditioning case 40 and/or the rear air conditioning case 50 to realize front passenger compartment and/or rear passenger compartment refrigeration.

The first valve element 33 and the battery heat exchanger 34 are disposed in the second flow section 312 in this order in a direction away from the first flow section 311, so that when the first valve element 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 will be appreciated that when cooling of the battery is not required, the first valve element 33 may be closed, preventing the flow of refrigerant to the battery heat exchanger 34.

In this embodiment, by disposing the first valve member 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, the piping design can be further simplified and the number of connectors and connector mounting seats can be reduced as compared with the case where a piping is separately provided to conduct the refrigerant to the battery and exchange heat.

It will be appreciated that the battery heat exchanger 34 may indirectly exchange heat with the battery of the vehicle through a cooling heat exchange module in the thermal management system, and in particular, a portion of the coolant heat exchange module is disposed between the battery heat exchanger 34 and the battery, and the coolant heat exchange module exchanges heat with both the battery heat exchanger 34 and the battery, thereby effecting heat transfer between the battery heat exchanger 34 and the battery.

Alternatively, the first valve element 33 may be configured as a throttle valve, and by adjusting the valve port size of the first valve element 33, the flow rate of the refrigerant flowing into the second flow section 312 may be controlled, thereby adjusting the cooling effect on the battery.

Further, a 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.

It can be appreciated that in the refrigerant heat exchange module, at least one of the front air conditioning cooling function, the air conditioning cooling function and the battery cooling function can be realized by controlling the on-off of the first valve member 33, and the operation state of the refrigerant heat exchange module can be flexibly adjusted. Also, in the present embodiment, by providing the third flow section 313 including the first sub-section 314 and the second sub-section 315, the refrigerant is conveyed to the front air conditioning unit 40 through the first sub-section 314, and the second sub-section 315 conveys the refrigerant to the rear air conditioning unit 50, it is possible to avoid the mutual influence of the refrigerant flowing to the front air conditioning unit 40 and the refrigerant of the rear air conditioning unit 50, thereby influencing the cooling effect of the front air conditioning unit 40 and/or the rear air conditioning unit 50.

Optionally, a second valve element mounting position may be provided in the first sub-section 314, where the second valve element mounting position is used to mount a second valve element, and the second valve element may be configured as a throttle valve, so that by adjusting the valve port size of the second valve element, the flow rate of the refrigerant flowing into the first sub-section 314 and the second sub-section 315 may be reasonably distributed, so as to adjust the cooling effect of the front air conditioner and/or the rear air conditioner. It will be appreciated that the second valve member may also be provided at the front air conditioning case 40 so as to avoid affecting the volume of the second flow field plate 32.

And/or, the first flow section 311 is provided with a third valve member installation position for installing the third valve member 36 which is unidirectionally conducted in a direction away from the outlet of the air heat exchanger 20, so that the refrigerant in the first, second and third flow sections 314, 315 and 313 can be prevented from flowing back to the first flow section 311 to affect the normal operation of the refrigerant heat exchange module.

With continued reference to fig. 3, in some embodiments, the first flow section 311, the second flow section 312 and the third flow section 313 extend along the edges of the second flow channel plate 32, the first flow section 311 includes an inlet end and outlet ends located at two sides of the inlet end, the second flow section 312 communicates with one outlet end, and the first sub-section 314 and the second sub-section 315 of the third flow section 313 communicate with the other outlet end, so that the positions of the first flow section 311, the second flow section 312 and the third flow section 313 in the second flow channel plate 32 are reasonably set to improve the space utilization of the second flow channel plate 32, and the first flow section 311, the second flow section 312 and the third flow section 313 extend along the edges of the second flow channel plate 32, so that corresponding valve elements and heat exchangers can be installed in the first flow section 311, the second flow section 312 and the third flow section 313 to reduce the assembly difficulty. Meanwhile, the plane where the first subsection 314 is located overlaps with the planes where the first flow section 311, the second subsection 315 and the second flow section 312 are located, so that the size of the planes where the first flow section 311, the second subsection 315 and the second flow section 312 are located can be reduced, and the overall volume of the second flow channel plate 32 can be reduced.

It will be appreciated that the first valve member 33, the battery heat exchanger 34, the second valve member and the third valve member 36 are assembled outside the second flow path plate 32 and disposed corresponding to the positions of the respective flow sections, and the actual positions of the first valve member 33, the battery heat exchanger 34, the second valve member and the third valve member 36 are not limited in this embodiment.

Fig. 5 is a schematic view of another structure of a refrigerant heat exchange module according to some embodiments of the application.

As shown in fig. 5, in some embodiments, the first flow passage 12 includes a fourth flow section 121, a fifth flow section 122, and a sixth flow section 123, the inlet of the fourth flow section 121 is in communication with the outlet of the compressor 11, the fourth flow section 121 is provided with a condenser mounting location for mounting the condenser 14 that exchanges heat with the coolant heat exchange module of the thermal management system, the fifth flow section 122 and the sixth flow section 123 are respectively in communication with the outlet of the fourth flow section 121, the outlet of the fifth flow section 122 is in communication with the inlet of the air heat exchanger 20, the outlet of the sixth flow section 123 is in communication with the inlet of the second flow section 312 and/or the third flow section 313, the fifth flow section 122 is provided with a fourth valve mounting location, and the sixth flow section 123 is provided with a fifth valve mounting location.

The fourth valve element installation position is used for installing the fourth valve element 15, the fifth valve element installation position is used for installing the fifth valve element 16, and the fourth valve element 15 and the fifth valve element 16 are respectively used for controlling the on-off of the fifth flow section 122 and the sixth flow section 123. It will be appreciated that when the fourth valve element 15 is open and the fifth valve element 16 is closed, the condenser 14 may be controlled to be closed, and the refrigerant flowing from the outlet of the compressor 11 may flow through the fourth flow section 121 and the fifth flow section 122 in sequence and 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 section 311 and through the first flow section 311 into the second flow section 312 and/or the third flow section 313 to perform at least one of a front air conditioning refrigeration function, a rear air conditioning refrigeration function and a battery cooling function; or at this time, the condenser 14 may be controlled to be turned on, 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 section 121, so as to release heat to the coolant heat exchange module, so that the coolant heat exchange module can perform the heating function of the front air conditioner and/or the rear air conditioner, and then the released refrigerant flows through the fifth flow section 122 and the air heat exchanger 20 in sequence and flows back to the inlet of the compressor 11. It will be appreciated that the front air conditioning case 40 and/or the rear air conditioning case 50 may also include an air condenser in communication with the coolant heat exchange module, such that when the coolant in the coolant heat exchange module exchanges heat with the coolant in the coolant heat exchange module and absorbs heat from the coolant, the coolant may flow into the air condenser and release heat to ambient air at the air condenser, and the air surrounding the air condenser may be converted to hot air, which is then directed to the passenger compartment by the fan, thereby providing heating to the passenger compartment.

When the fourth valve element 15 is closed and the fifth valve element 16 is opened, the condenser 14 can be controlled to be opened, so that the refrigerant flowing out of the compressor 11 exchanges heat with the cooling liquid heat exchange module through the condenser 14 at the fourth flow section 121, heat is released to the cooling liquid heat exchange module, then the exothermic refrigerant can flow to the second flow section 312 and/or the third flow section 313 through the sixth flow section 123, when the refrigerant flows into the second flow section 312, the refrigerant can exchange heat with the battery through the battery heat exchanger 34 in the second flow section 312, heat generated in the operation process of the battery is absorbed, the utilization of the heat of the battery is realized, and the refrigerant after heat absorption at the battery heat exchanger 34 can flow back to the compressor 11; and/or, when the refrigerant flows into the third flow section 313, the refrigerant may flow into the front air conditioning case 40 and/or the rear air conditioning case 50 through the third flow section 313, exchange heat with surrounding air at an evaporator in the front air conditioning case 40 and/or the rear air conditioning case 50, absorb heat in the surrounding air of the evaporator, convert the surrounding air into cold air, and the vapor in the air may be exothermically solidified into a liquid state, thereby reducing the vapor content in the air, and then, the dehumidified cold air is driven by the fan to flow to the passenger compartment, so that the passenger compartment may be dehumidified.

Alternatively, in front air conditioning case 40 and/or rear air conditioning case 50, the evaporator may be located upstream of the air condenser in the air outlet direction. When the fourth valve element 15 and the fifth valve element 16 may be opened simultaneously, the condenser 14 may be opened, so that the refrigerant flowing out of the compressor 11 may exchange heat with the coolant heat exchange module through the condenser 14 at the fourth flow section 121, heat may be released to the coolant heat exchange module, the coolant in the coolant heat exchange module may flow into the air condenser in the front air conditioning box 40 and/or the rear air conditioning box 50 after absorbing the heat in the refrigerant and release the heat to the surroundings, at the same time, the refrigerant flowing out of the condenser 14 may flow into the fifth flow section 122 and the sixth flow section 123 simultaneously, the refrigerant flowing into the fifth flow section 122 may flow back to the compressor 11 through the air heat exchanger 20, and the refrigerant flowing into the sixth flow section 123 may flow into the evaporator in the front air conditioning box 40 and/or the rear air conditioning box 50 through the third flow section 313, dehumidify the air around the evaporator, and then the dehumidified cold air may flow through the air condenser under the driving of the fan first, absorb part of the heat in the coolant in the air condenser, and then flow into the cabin in winter, thereby avoiding the passenger cabin from flowing into the passenger cabin in winter, and improving the comfort mode.

It will be appreciated that when the fourth valve element 15 and the fifth valve element 16 are opened simultaneously, the refrigerant heat exchange module may also implement other combinations of functions, for example, the refrigerant heat exchange module may implement a battery cooling function and a dehumidification function of the front and rear air conditioners simultaneously, or the refrigerant heat exchange module may implement a refrigeration function of the front and rear air conditioners and a dehumidification function of the front and rear air conditioners simultaneously, or the refrigerant heat exchange may also implement a refrigeration function of the front and rear air conditioners and a battery heat recycling function simultaneously, and the implementation of various functions of the refrigerant heat exchange module may be flexibly adjusted as required in the application process, so long as contradiction situations such as implementing the refrigeration function and the heating function of the front and rear air conditioners simultaneously are avoided.

Alternatively, the fourth valve element 15 may be configured as a throttle valve, and the flow rate of the refrigerant flowing into the fifth flow section 122 and the sixth flow section 123 may be reasonably adjusted by controlling the valve port size of the fourth valve element 15 when the fourth valve element 15 and the fifth valve element 16 are simultaneously opened.

In the present embodiment, by controlling the states of the fourth valve element 15 and the fifth valve element 16, the states of the refrigerant heat exchange module can be flexibly adjusted to realize different functions of the refrigerant heat exchange module. Meanwhile, by disposing the condenser 14 in the first flow passage 12 and rationally designing the flow passages of the first flow passage 12 and the second flow passage 31 to achieve the above-described respective functions, the pipe design can be further simplified and the number of joints and joint mounting seats can be reduced as compared with the case where the above-described functions are achieved by the pipe design.

Alternatively, the fourth flow section 121 may be provided with a second sensor mounting location for mounting a second sensor for detecting the pressure and/or temperature of the refrigerant in the fourth flow section 121. It will be appreciated that a second sensor may be provided at the outlet of the condenser 14 for detecting the pressure and/or temperature of the refrigerant after heat has been released from the condenser 14.
