[0055] The following describes in detail the specific implementation manners of the present disclosure with reference to the accompanying drawings. It should be understood that the specific implementation manners described herein are only for explaining and illustrating the present disclosure, and are not used to limit the present disclosure.

[0056] In the present disclosure, unless otherwise stated, "inner" and "outer" refer to the inner and outer of the relevant components. In addition, terms such as "first", "second", etc. are only used for differential description and cannot be construed as indicating or implying relative importance.

[0057] In the description of the present disclosure, it should also be noted that, unless otherwise clearly defined and limited, the terms "arranged" and "connected" should be understood in a broad sense. For example, it can be a fixed connection, a detachable connection, or an integral connection. It can be directly connected or indirectly connected through an intermediate medium, and it can be the communication inside two components. For those of ordinary skill in the art, the specific meanings of the above terms in the present disclosure can be understood according to specific circumstances.

[0058] With the development of new energy vehicles, the thermal management system needs to implement more and more working modes to meet the requirements of different usage scenarios.

[0059] In the thermal management integration module in the related art, the integrated components are limited, and the number of working modes achieved is limited, which cannot meet the thermal management requirements of the vehicle in different scenarios. For example, in the usage scenario of long-distance high-speed driving in winter, when the battery needs to be cooled and the passenger compartment needs heating at the same time, the thermal management integration module in the related art cannot achieve this function, resulting in a still low degree of integration.

[0060] For this reason, as Figures 1-8 shown, one aspect of the present disclosure provides a thermal management integration module, including a refrigerant integration component, and the refrigerant integration component includes a first flow channel plate 1, a first switching valve 3, and a first expansion valve 8.

[0061] The first switching valve 3 is integrated on the first flow channel plate 1, the first expansion valve 8 is connected to the first flow channel plate 1, and the first expansion valve 8 is adapted to communicate with the battery heat exchanger 104 to throttle the refrigerant flowing through the battery heat exchanger 104. A first refrigerant connection interface 4 is arranged on the first flow channel plate 1, and the first refrigerant connection interface 4 is used to connect with the refrigerant outlet of the inner condenser 102, and the first refrigerant connection interface 4 is directly conducted or cut off from one end of the first expansion valve 8 through the first switching valve 3.

[0062] Wherein, the first flow channel plate 1 is used for the refrigerant to flow inside it to realize the guiding of the refrigerant flow. And the first switching valve 3 can control the direct conduction or cut-off between the first refrigerant connection interface 4 and one end of the first expansion valve 8, so that the refrigerant flowing out of the inner condenser 102 can selectively flow directly into the first expansion valve 8 or not.

[0063] In the above technical solution, through the first switching valve 3 provided, the first refrigerant connection interface 4 can be directly communicated with one end of the first expansion valve 8. Here, the direct communication means that there is no other component structure in the middle. The first refrigerant connection interface 4 is connected to the internal condenser 102, and the internal condenser 102 can transfer the heat of the refrigerant to the passenger compartment. In this way, heating of the passenger compartment can be achieved. Then, after throttling by the first expansion valve 8, it can be used for cooling other parts, meeting the requirements of different application scenarios, such as cooling the battery, and meeting the usage scenarios of long-distance high-speed driving in winter. This thermal management integrated module has a higher degree of integration. Integrating the first switching valve 3 on the first flow channel plate 1 can simplify the layout of related components, improve space utilization rate, reduce the weight of the whole vehicle, reduce costs and energy consumption, and improve the endurance ability.

[0064] Optionally, in an embodiment of the present disclosure, a first refrigerant flow channel 5 and a second refrigerant flow channel 6 are provided in the first flow channel plate 1. The first end of the first refrigerant flow channel 5 is connected to the first refrigerant connection interface 4, the second end of the first refrigerant flow channel 5 is connected to one end of the first switching valve 3, the first end of the second refrigerant flow channel 6 is connected to the other end of the first switching valve 3, and the second end of the second refrigerant flow channel 6 is communicated with one end of the first expansion valve 8. By providing the first refrigerant flow channel 5 and the second refrigerant flow channel 6, it is convenient for the refrigerant to flow in the first flow channel plate 1, realizing an integrated design, without the need to additionally set up connection pipelines, reducing costs and space occupation.

[0065] Optionally, in an embodiment of the present disclosure, the thermal management integrated module further includes a second expansion valve 7. The second expansion valve 7 is integrated on the first flow channel plate 1. The inlet of the second expansion valve 7 is connected to the second end of the first refrigerant flow channel 5, and the outlet of the second expansion valve 7 is connected to the first end of the second refrigerant flow channel 6. The second expansion valve 7 and the first switching valve 3 are in parallel connection. By connecting the second expansion valve 7 and the first switching valve 3 in parallel, the refrigerant flowing out of the internal condenser 102 can selectively flow through the second expansion valve 7 or the first switching valve 3 after entering the thermal management integrated module through the first refrigerant connection interface 4, realizing the switching of different working modes.

[0066] Among them, when the refrigerant flowing out of the internal condenser 102 undergoes throttling expansion through the second expansion valve 7, it can absorb heat and evaporate, and can absorb the heat of the coolant, thus realizing heat dissipation of structures such as the electric drive. It should be noted that specific adjustment and control can be carried out according to the flow direction of the coolant, and no more restrictions are imposed here.

[0067] Optionally, in an embodiment of the present disclosure, the thermal management integration module further includes a heat exchanger 2 and a first one-way valve 9.

[0068] Among them, the heat exchanger 2 can realize the heat exchange between the refrigerant and the coolant, so that the heat transfer direction can be controlled and different working modes can be realized. The first one-way valve 9 can limit the refrigerant from flowing out of the refrigerant outlet of the heat exchanger 2 and will not flow back from the refrigerant outlet of the heat exchanger 2. By connecting the second refrigerant connection interface 13 provided to the battery heat exchanger 104, and the second refrigerant connection interface 13 is connected to the first expansion valve 8 through the fifth refrigerant flow channel 12, the refrigerant flowing out of the refrigerant outlet of the heat exchanger 2 can undergo a phase change after throttling expansion through the first expansion valve 8.

[0069] In some examples, the first expansion valve 8 can be a two-way electronic expansion valve, that is to say, the first expansion valve 8 can adjust the direction of throttling expansion according to the different directions of the refrigerant entering and flowing out of the first expansion valve 8, so that the thermal management integration module can adapt to more working modes. Of course, in other examples, the first expansion valve 8 can also be a one-way electronic expansion valve.

[0070] Optionally, in an embodiment of the present disclosure, the thermal management integration module further includes a second one-way valve 14.

[0072] Wherein, the third refrigerant connection interface 22 is used to connect to the battery heat exchanger 104, and the fourth refrigerant connection interface 23 is used to connect to the outlet of the compression pump.

It should be noted that the internal condenser 102 refers to the in-vehicle condenser 102 for realizing in-vehicle heat exchange, and the external condenser 103 refers to the out-of-vehicle condenser 103 for realizing out-of-vehicle heat exchange.

[0096] Among them, this thermal management system has multiple working modes, specifically as follows.

[0097] The first working mode is the air-conditioning refrigeration mode. As Figure 10 shown, among them, the compressor 100 discharges high-temperature and high-pressure gaseous refrigerant, which enters the external condenser 103. After the refrigerant releases heat and liquefies in the external condenser 103, it forms a medium-temperature and high-pressure liquid, which enters the thermal management integration module through the sixth refrigerant connection interface 32, passes through the eleventh refrigerant flow channel 30, passes through the third one-way valve 28, and then passes through the twelfth refrigerant flow channel 26 and the third refrigerant flow channel 10 to enter the fourth expansion valve 29 for throttling expansion. The low-temperature and low-pressure gas-liquid mixture flows out from the seventh refrigerant connection interface 33 through the thirteenth refrigerant flow channel 31 and enters the evaporator 105 to absorb heat and evaporate, that is, absorb the heat in the environment, so that the temperature of the passenger compartment drops. The low-temperature and low-pressure gas returns to the thermal management integration module through the eighth refrigerant connection interface 34, passes through the fifteenth refrigerant flow channel 48, the fourteenth refrigerant flow channel 27, and the fifth refrigerant connection interface 24, enters the gas-liquid separator 108 for gas-liquid separation, and then returns to the compressor 100 for cyclic operation.

[0098] The second working mode is the air-conditioning heating mode. As Figure 11As shown, the compressor 100 discharges high-temperature and high-pressure gaseous refrigerant, which enters the internal condenser 102. The refrigerant releases heat in the internal condenser 102, and the hot air is blown into the vehicle interior by the blower to heat the vehicle interior. Of course, PTC heating can also be combined. The refrigerant coming out of the internal condenser 102 enters the thermal management integration module through the first refrigerant connection interface 4, flows through the first refrigerant flow path 5, enters the second expansion valve 7 for throttling expansion, passes through the second refrigerant flow path 6, absorbs heat and evaporates in the heat exchanger 2. The refrigerant coming out of the heat exchanger 2 enters the fourth switching valve 25 through the third refrigerant flow path 10, then enters the gas-liquid separator 108 through the fourteenth refrigerant flow path 27 and the fifth refrigerant connection interface 24 for gas-liquid separation, and then returns to the compressor 100 to perform cyclic operation.

[0099] The third working mode, the battery heating mode, as Figure 12 As shown, the high-temperature and high-pressure refrigerant flows out of the compressor 100, enters the thermal management integration module through the fourth refrigerant connection interface 23, passes through the ninth refrigerant flow path 20, the second switching valve 15 and the eighth refrigerant flow path 19, enters the third expansion valve 17, and then flows into the battery heat exchanger 104 through the seventh refrigerant flow path 18 and the third refrigerant connection interface 22. At this time, the refrigerant condenses and releases heat to heat the battery, realizing battery heating, improving battery life, improving battery efficiency, increasing battery capacity at low temperatures and the vehicle's cruising range, and effectively shortening the charging time. The refrigerant after releasing heat enters the thermal management integration module through the second refrigerant connection interface 13, passes through the fifth refrigerant flow path 12, enters the first expansion valve 8 for throttling expansion, passes through the fourth refrigerant flow path 11, the second one-way valve 14 and the second refrigerant flow path 6, enters the heat exchanger 2 to absorb heat and evaporate. The refrigerant coming out of the heat exchanger 2 enters the fourth switching valve 25 through the third refrigerant flow path 10, then enters the gas-liquid separator 108 through the fourteenth refrigerant flow path 27 and the fifth refrigerant connection interface 24 for gas-liquid separation, and then returns to the compressor 100 to perform cyclic operation.

[0100] The fourth working mode, the battery cooling mode, as Figure 13As shown, the compressor 100 discharges high-temperature and high-pressure gaseous refrigerant, which enters the external condenser 103. After the refrigerant releases heat and liquefies in the external condenser 103, it forms a medium-temperature and high-pressure liquid, which enters the thermal management integration module through the sixth refrigerant connection interface 32, passes through the eleventh refrigerant flow channel 30, the third one-way valve 28, and enters the first one-way valve 9 through the twelfth refrigerant flow channel 26 and the sixth refrigerant flow channel 47. Then, it enters the first expansion valve 8 through the fourth refrigerant flow channel 11. After throttling expansion, it passes through the fifth refrigerant flow channel 12 and enters the battery heat exchanger 104 from the second refrigerant connection interface 13. At this time, the low-temperature and low-pressure gas-liquid mixture absorbs the battery heat and evaporates, realizing the cooling when the power battery temperature is too high. The refrigerant enters the thermal management integration module again through the third refrigerant connection interface 22, passes through the seventh refrigerant flow channel 18 and the third expansion valve 17, and then passes through the eighth refrigerant flow channel 19, the third switching valve 16, the tenth refrigerant flow channel 21, the fourteenth refrigerant flow channel 27, and the fifth refrigerant connection interface 24 to enter the gas-liquid separator 108 for gas-liquid separation, and then returns to the compressor 100 for cyclic operation.

[0101] The fifth working mode is battery cooling + air-conditioning heating. For example, when the ambient temperature is lower than 5°C and after rapid charging and then driving at high speed, as Figure 14 As shown, the compressor 100 discharges high-temperature and high-pressure gaseous refrigerant. After flowing out of the compressor 100, the refrigerant enters the internal condenser 102. The refrigerant releases heat in the internal condenser 102, and the hot air is blown into the vehicle through the blower to heat the vehicle interior. Of course, PTC heating can also be combined. The refrigerant coming out of the internal condenser 102 enters the thermal management integration module through the first refrigerant connection interface 4, passes through the first refrigerant flow channel 5 and enters the first switching valve 3, so that it directly enters the heat exchanger 2 through the second refrigerant flow channel 6. The refrigerant coming out of the heat exchanger 2 passes through the third refrigerant flow channel 10 and the sixth refrigerant flow channel 47 to enter the first one-way valve 9, then enters the first expansion valve 8 through the fourth refrigerant flow channel 11 for throttling expansion, and then enters the battery heat exchanger 104 through the fifth refrigerant flow channel 12 and the second refrigerant connection interface 13. At this time, the low-temperature and low-pressure gas-liquid mixture absorbs the battery heat and evaporates, realizing the cooling when the power battery temperature is too high. The refrigerant coming out of the battery heat exchanger 104 enters the thermal management integration module again through the third refrigerant connection interface 22, passes through the seventh refrigerant flow channel 18 and the third expansion valve 17, and then passes through the eighth refrigerant flow channel 19, the third switching valve 16, the tenth refrigerant flow channel 21, the fourteenth refrigerant flow channel 27, and the fifth refrigerant connection interface 24 to enter the gas-liquid separator 108 for gas-liquid separation, and then returns to the compressor 100 for cyclic operation.

One path enters the thermal management integration module from the fourth refrigerant connection interface 23, passes through the ninth refrigerant flow path 20, the second switching valve 15, and the eighth refrigerant flow path 19, enters the third expansion valve 17, and then flows into the battery heat exchanger 104 from the seventh refrigerant flow path 18 and the third refrigerant connection interface 22. At this time, the refrigerant condenses and releases heat to heat the battery, realizing battery heating, improving battery life, improving battery efficiency, increasing battery capacity and vehicle endurance at low temperatures, and effectively shortening the charging time. The refrigerant after releasing heat enters the thermal management integration module through the second refrigerant connection interface 13, passes through the fifth refrigerant flow path 12, enters the first expansion valve 8 for throttling expansion, passes through the fourth refrigerant flow path 11, the second check valve 14, and the second refrigerant flow path 6, enters the heat exchanger 2 to absorb heat and evaporate. The refrigerant coming out of the heat exchanger 2 enters the fourth switching valve 25 through the third refrigerant flow path 10, and then enters the gas-liquid separator 108 through the fourteenth refrigerant flow path 27 and the fifth refrigerant connection interface 24 for gas-liquid separation; the other path enters the external condenser 103. After the refrigerant releases heat and liquefies in the external condenser 103, it forms a medium-temperature and high-pressure liquid, enters the thermal management integration module through the sixth refrigerant connection interface 32, passes through the eleventh refrigerant flow path 30, passes through the third check valve 28, and then enters the fourth expansion valve 29 through the twelfth refrigerant flow path 26 and the third refrigerant flow path 10 for throttling expansion. The low-temperature and low-pressure gas-liquid mixture flows out from the seventh refrigerant connection interface 33 through the thirteenth refrigerant flow path 31 and enters the evaporator 105 to absorb heat and evaporate, that is, absorb the heat in the environment, causing the temperature of the passenger compartment to drop. The low-temperature and low-pressure gas returns to the thermal management integration module through the eighth refrigerant connection interface 34, enters the gas-liquid separator 108 through the fourteenth refrigerant flow path 27 and the fifth refrigerant connection interface 24 for gas-liquid separation, and then returns to the compressor 100 for cyclic operation.
