[0083] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of this application, and not all of them. All other embodiments obtained by those skilled in the art based on the embodiments of this application without creative effort are within the protection scope of this application.

[0084] This application provides a thermal management system; please refer to [link / reference]. Figures 1 to 10 .

[0085] The thermal management system includes a refrigerant subsystem 01; this refrigerant subsystem 01 includes a compressor 1, a gas-liquid separator 11, a regenerator 12, and a first heat exchange flow path 001. The compressor 1 includes an exhaust port 101 and a return port 102; the gas-liquid separator 11 is configured to have a liquid storage function; the regenerator 12 includes a first passage 121 and a second passage 122 that exchanges heat with the first passage 121; a first end of the first heat exchange flow path 001 is connected to the exhaust port 101, and a second end is connected to the inlet of the gas-liquid separator 11; the liquid outlet of the gas-liquid separator 11 is connected to the first end of the first passage 121, the second end of the first passage 121 is connected to the first end of the second heat exchange flow path 002, the second end of the second heat exchange flow path 002 is connected to the first end of the second passage 122, and the second end of the second passage 122 is connected to the return port 102. (See also...) Figure 1 Understandably, when compressor 1 operates, the compressed heat exchange medium (refrigerant) is transported through exhaust port 101 to the first heat exchange flow path 001, passes through the gas-liquid separator 11 with liquid storage function, and is then transported through its drain port to the first passage 121 of regenerator 12. It then passes through the second heat exchange flow path 002 to the second passage 122 of regenerator 12, and finally returns to the return port 102 of compressor 1, thus completing the refrigerant circulation process. During this process, the compressed heat exchange medium exchanges heat with the outside through the first heat exchange flow path 001. The heat-exchanged medium then enters the gas-liquid separator 11, which has a liquid storage function, acting as a gas-liquid separator-liquid storage integrator. This improves the system's integration, reduces the number of components, and increases the utilization rate of components during use. The use of a gas-liquid separator reduces the number of components, improving the reliability of the thermal management system. Furthermore, the included regenerator 12 heats any liquid that may be present in the refrigerant flowing back to the compressor 1, causing it to vaporize and preventing liquid slugging in the compressor 1, thus further enhancing the reliability of the thermal management system. In the gas-liquid separator 11, after the heat exchange medium enters its storage chamber, the sudden expansion of space reduces the refrigerant flow rate. Due to the difference in specific gravity between the gas and liquid phases, under gravity, the liquid refrigerant is distributed at the bottom of the storage chamber, while the gaseous refrigerant is distributed at the top. This achieves gas-liquid separation and liquid storage in the storage chamber. The cold medium then enters the first passage 121, and the cold medium in the first passage 121 then flows through the second heat exchange passage 002 to the second passage 122. The first passage 121 and the second passage 122 can exchange heat to improve the efficiency of the system.

[0086] In some implementations, please refer to Figure 2The gas-liquid separator 11 with liquid storage function includes: a container 111 for containing a cooling medium; the container 111 includes: a first inlet 112 for introducing a gas-liquid mixed heat exchange medium; a first outlet 113 for discharging the gaseous heat exchange medium; and a second outlet 114 for discharging the liquid heat exchange medium; the container 111 is also provided with an exhaust pipe 115, one end of which is connected to the first outlet 113, and the other end is configured to discharge the gaseous heat exchange medium in the container 111, that is, during use, the other end of the exhaust pipe 115 does not contact the liquid heat exchange medium. It can be understood that the gas-liquid mixed heat exchange medium entering the container 111 has its liquid phase at the bottom and its gas phase at the top along the direction of gravity, thus separating the gas and liquid. Along the direction of gravity, to facilitate the discharge of the gaseous heat exchange medium, the first outlet 113 is located at the top of the container, and the second outlet 114 is located at the bottom or lower part of the container 111. In addition, the exhaust pipe 115 is U-shaped and has a return hole near the liquid heat exchange medium so that when the gas-liquid heat exchange medium is discharged, a portion of the refrigeration oil can be carried out and flow back to the compressor 1.

[0087] In some implementations, please refer to Figure 1 and Figure 4 The second heat exchange path 002 is used for refrigeration. At this time, the compressor 1 operates, and the compressed refrigerant undergoes heat exchange through the first heat exchange path 001. The first heat exchange path 001 is equipped with a condenser, where a portion of the refrigerant condenses into liquid refrigerant, which then enters the gas-liquid separator 11 with liquid storage function, and passes through the regenerator 12 to the second heat exchange path 002. The second heat exchange path 002 has an expansion valve and an evaporator 7. The refrigerant changes from liquid to gas and cools down through the expansion valve. After heat exchange in the evaporator 7, it flows to the second passage 122. The refrigerant in the second passage 122 can exchange heat with the refrigerant in the first passage 121, subcooling the refrigerant in the first passage 121 to increase the cooling capacity and efficiency. Meanwhile, the refrigerant in the second passage 122 is heated, converting a small portion of the liquid refrigerant into a gaseous state to prevent liquid slugging in the compressor 1.

[0088] In some implementations, please refer to Figure 1 and Figure 5 The exhaust end of the gas-liquid separator 11 is connected to the return port 102 via a fourth control valve 24. It can be understood that the fourth control valve 24 can controllably cut off or connect the passage between the exhaust end of the gas-liquid separator 11 and the return port 102 of the compressor 1 to control the flow of the medium. Specifically, the fourth control valve 24 can be configured as an electrically controlled solenoid valve to allow for rapid control of the pipeline's on / off state.

[0089] In some implementations, please refer to Figure 3 and Figure 10The gas-liquid separator 11 and the regenerator 12 are integrated into one unit, forming a liquid storage gas-liquid separation and regenerator integrated unit 13, which further improves the integration of the refrigerant subsystem 01, further reduces the number of components, and reduces the number of pipeline connections.

[0090] Specifically, the integrated liquid-gas-liquid separation and regenerative heat exchanger 13 includes: a container 111 for containing a cooling medium; the container 111 includes: a first inlet 112 for introducing a gas-liquid mixed heat exchange medium; a first outlet 113 for discharging a gaseous heat exchange medium; and a second outlet 114 for discharging a liquid heat exchange medium; wherein, a heat exchange element 116 is provided inside the container 111, and the inlet and outlet of the heat exchange element 116 are connected to the outside of the container 111. It can be understood that by directly integrating the regenerator 12, the gas-liquid separator 11, and the liquid storage container into one unit by directly providing the heat exchange element 116 inside the container 111, the number of components can be significantly reduced, as can the volume and weight. Liquid storage, gas-liquid separation, and heat exchange functions can be achieved through a single container 111. The heat exchange element 116 has at least one medium passage, typically one in number. The medium flowing in this medium passage exchanges heat with the heat exchange medium inside the container 111, and the two media do not directly contact each other. During refrigeration, the medium flowing within heat exchanger 116 cools the heat exchange medium within container 111, while the heat exchange medium within container 111 heats the medium within heat exchanger 116. Furthermore, the gas-liquid mixed heat exchange medium entering container 111 has its liquid phase at the bottom and gas phase at the top along the direction of gravity, thus separating the gas and liquid phases. To facilitate the discharge of the gaseous heat exchange medium along the direction of gravity, a first outlet 113 is located at the top rear of the container, and a second outlet 114 is located at the bottom or lower part of container 111.

[0091] In some implementations, please refer to Figure 3 The liquid-gas-liquid separation and regenerative integrator 13 further includes an exhaust pipe 115. One end of the exhaust pipe 115 is connected to the first outlet 113, and the other end is configured to discharge the gaseous heat exchange medium inside the container 111. It is understood that the exhaust pipe 115 facilitates the discharge of the gaseous medium. The exhaust pipe 115 can have various shapes, such as U-shaped, S-shaped, L-shaped, etc. One end of the exhaust pipe 115 is suspended above the container 111, in contact with the gaseous heat exchange medium, and the other end is connected to the first outlet 113.

[0092] Furthermore, the exhaust pipe 115 is U-shaped, and a return hole is provided at the bottom of the exhaust pipe 115 in the direction of gravity. It is understood that the U-shape of the exhaust pipe 115 ensures that the gaseous heat exchange medium can be discharged even when at least part of the exhaust pipe 115 is in contact with the liquid phase heat exchange medium in the container 111. The return hole ensures that a small amount of refrigerant oil flows back when the gaseous heat exchange medium is discharged to the compressor return port 102, preventing refrigerant oil retention and extending the life of the compressor 1. Specifically, along the direction of gravity, the U-shaped exhaust pipe 115 opens upwards, with at least part of its lower portion located in the liquid phase medium, and the portion located in the liquid phase medium has a return hole. Typically, the return hole is located on the exhaust pipe 115 near the bottom of the container 111, and the number of return holes can be multiple, depending on the required return volume.

[0093] In some embodiments, the heat exchanger 116 is a coil heat exchanger 116 or a plate heat exchanger 116 to quickly exchange heat with the heat exchange medium inside the container 111. Typically, the heat exchanger 116 is configured as a coil heat exchanger 116 or a plate heat exchanger 116 and is installed inside the container 111 for heat exchange.

[0094] In some embodiments, the heat exchanger 116 is configured to contact the liquid heat exchange medium within the container 111 for heat exchange. It is understood that contact between the heat exchanger 116 and the liquid medium during heat exchange, regardless of the form of the heat exchanger 116, can improve the heat exchange efficiency of the device. Therefore, the heat exchanger 116 located within the container 111 is preferably in contact with or immersed in the liquid medium, or positioned near the bottom of the container 111.

[0095] The inlet and outlet of the heat exchanger 116 correspond to the inlet and outlet of the second passage 122 of the regenerator 12, so that the flow path relationship before and after the integration of the regenerator and the gas-liquid separator can be clearly understood. The first passage 121 of the regenerator 12 is integrated into the heat exchange medium flow path in the container 111, thus eliminating the need for the first passage 121 of the regenerator 12. The second end of the first passage 121 is the same as the drain end of the gas-liquid separator 11. It can be understood that in order to make the structure of the liquid storage gas-liquid separation regenerator integrated unit 13 more compact, the regenerator 12 and the gas-liquid separator 11 with liquid storage function are integrated into one unit. Therefore, some structures are redundant. The heat exchanger 116 eliminates the first passage 121, which is configured as the flow space of the medium in the container 111. The second end (drain end) of the first passage 121 is the second outlet 114 of the container 111.

[0096] In some implementations, please refer to Figure 1 and Figure 4 , Figure 8The first heat exchange path 001 is used for heat exchange with the coolant subsystem 02. It is understood that the thermal management system has multiple thermal management modes. By exchanging heat with the refrigerant subsystem 01 through the first heat exchange path 001, the thermal management efficiency of the vehicle can be improved, and energy consumption reduced. The first heat exchange path 001 includes a first heat exchanger 10; a first end of the first heat exchanger 10 is connected to the exhaust port 101, and a second end is connected to the inlet of the gas-liquid separator 11, with the first end and second end of the first heat exchanger 10 communicating. It is understood that the heat exchange medium after the compressor 1 has performed work enters the first heat exchanger 10 for heat exchange, improving the energy utilization rate of the system. For example, during cooling, the first heat exchange path 001 releases heat through the first heat exchanger 10; during heating or battery heating, the first heat exchange path 001 absorbs heat through the first heat exchanger 10.

[0097] Furthermore, the first heat exchange flow path 001 also includes a first control valve 21, which is located on the pipeline between the exhaust port 101 and the first end of the first heat exchanger 10. It is understood that the first control valve 21 controls the flow path between the first heat exchange flow path 001 and the exhaust port 101 of the compressor 1 for system thermal management. The first control valve 21 can be a solenoid valve, and its main function is to cut off or connect the flow paths on both sides.

[0098] In some implementations, please refer to Figure 1 , Figure 5 , Figure 6 and Figure 9 The refrigerant subsystem 01 includes a fourth heat exchange path 004, which is used to regulate the vehicle interior temperature. The first end of the fourth heat exchange path 004 is connected to the exhaust port 101, and the second end is connected to the first end of the first heat exchanger 10. It can be understood that while the second heat exchange path 002 typically regulates the vehicle's cooling, the fourth heat exchange path 004 is needed to regulate the vehicle's heating. The compressor 1 performs work on the heat exchange medium, and the heat from the high-temperature, high-pressure heat exchange medium can be transferred to the vehicle interior through the fourth heat exchange path 004 to regulate the interior temperature. If the fourth heat exchange path 004 is connected in parallel to the first heat exchange path 001 on the pipeline between the first heat exchanger 10 and the compressor 1, then the first control valve 21 needs to be closed.

[0099] The fourth heat exchange path 004 includes a first condenser 8 and a second control valve 22 connected in series. The first condenser 8 allows the high-temperature heat exchange medium discharged from the compressor 1 to be condensed and cooled to obtain heat from the heat exchange medium. The second control valve 22 controls the opening and closing of the heat exchange medium flow channel for regulation of the thermal management system. Specifically, the heat exchange medium is refrigerant, and the second control valve 22 also has the function of expanding and depressurizing the refrigerant; therefore, the second control valve 22 can be an electronic expansion valve. The second control valve 22 can also be a valve with a broken-line control curve, acting as an expansion valve with a throttling effect at partial opening and functioning as a flow channel without throttling at partial opening. For example, when the valve opening is 0-350 steps, the valve diameter varies between 0-1.65mm, acting as an expansion valve for throttling. When the valve opening is 350-500 steps, the valve diameter varies between 1.65-10mm. When the valve is opened to its maximum number of steps, there is no throttling effect, equivalent to a flow channel. The method for regulating the temperature inside the vehicle is as follows: the gas is sent to the first condenser 8 by a blower to obtain heat, and then transported to the vehicle interior through the air duct to heat the passenger compartment. After passing through the first condenser 8, the high-temperature and high-pressure gaseous refrigerant is condensed into a medium-temperature and high-pressure mixed refrigerant (liquid and gaseous). After expanding and depressurizing through the second control valve 22, it forms a low-temperature and low-pressure refrigerant. It absorbs heat through the second heat exchanger and then enters the gas-liquid separator 11. The third control valve 23 is closed, and the fourth control valve 24 is opened, allowing the gaseous refrigerant to flow back to the compressor 1.

[0100] In some implementations, please refer to Figure 1 and Figure 4 , Figure 10 The second heat exchange flow path 002 is used to regulate the vehicle interior temperature. The second heat exchange flow path 002 includes a third control valve 23 and an evaporator 7 connected in series; the third control valve 23 is connected to the second end of the first passage 121, and the evaporator 7 is connected to the first end of the second passage 122. It can be understood that the second heat exchange flow path 002 cooperates with the first heat exchange flow path 001 to regulate the vehicle interior temperature. The evaporator 7 on the second heat exchange flow path 002 is used to evaporate the refrigerant passing through it to obtain a low temperature, providing cool air to the vehicle interior for refrigeration regulation. The third control valve 23 is used to cut off or connect the pipes passing through it. Furthermore, the third control valve 23 is configured as an expansion valve to better control the evaporation of the refrigerant.

[0101] In some implementations, please refer to Figure 1 , Figure 6 , Figure 7 and Figure 8The refrigerant subsystem 01 further includes a third heat exchange path 003 for heat exchange with the battery pack. The first end of the third heat exchange path 003 is connected to the second end of the first passage 121, and the second end is connected to the first end of the second passage 122. It can be understood that by setting the third heat exchange path 003 so that its first end is connected to the second end of the first passage 121 and its second end is connected to the first end of the second passage 122, cooling regulation of the battery pack can be achieved. Specifically, by controlling the first control valve 21 to open and the second control valve 22 to close, the refrigerant, after heat exchange through the first heat exchange path 001, flows through the first passage 121 to the battery pack heat exchanger 3 to heat the battery pack. The refrigerant after passing through the battery pack heat exchanger 3 then flows through the second passage 122 to heat the refrigerant in the first passage 121, and then flows back to the compressor 1. This can increase the cooling capacity and prevent liquid slugging in the compressor 1.

[0102] Furthermore, the third heat exchange path 003 includes a fifth control valve 25 and a battery pack heat exchanger 3 connected in sequence. The fifth control valve 25 is connected to the second end of the first passage 121, and the battery pack heat exchanger 3 is connected to the first end of the second passage 122. It is understood that the fifth control valve 25 can control the on / off state and flow rate of the refrigerant. When the third heat exchange path 003 is connected in parallel with other heat exchange paths (such as the second heat exchange path 002), it can control the operating flow path. Typically, the fifth control valve 25 is configured as a throttling valve, which has the functions of throttling and pressure reduction, and regulating flow rate. It is used in refrigeration systems to convert high-temperature, high-pressure liquid refrigerant into a low-temperature, low-pressure liquid-gas mixture refrigerant.

[0103] In some implementations, please refer to Figure 1 The connection or disconnection between the battery pack heat exchanger 3 and the first end of the second passage 122 is controlled by a sixth control valve 26. It can be understood that the sixth control valve 26 controls the connection or disconnection of the pipeline between the battery pack heat exchanger 3 and the first end of the second passage 122, especially when connected in parallel with the second heat exchange flow path 002. When the battery pack does not require a heat exchanger, the sixth control valve 26 is closed. Furthermore, adjusting the opening of the sixth control valve 26 can adjust the evaporation pressure of the refrigerant in the third heat exchange flow path 003, thereby regulating the evaporation temperature of the refrigerant in the battery branch to the target evaporation temperature and preventing the evaporation temperature from being too low. This sixth control valve 26 can be a large-diameter throttling valve.

[0104] In some implementations, please refer to Figure 1The first heat exchange flow path 001 includes a first heat exchanger 10, which has a first end. The first end of the first heat exchanger 10 is connected to the exhaust port 101, and the second end is connected to the inlet of the gas-liquid separator 11. The first end and the second end of the first heat exchanger 10 are in communication. The fifth control valve 25 is connected to the first end of the first heat exchanger 10 via a first check valve 29, which restricts fluid flow from the first heat exchanger 10 to the fifth control valve 25. This configuration connects the first heat exchange flow path 001 to the third heat exchange flow path 003 and defines the direction of fluid flow.

[0105] A second check valve 30 is provided on the pipeline between the fifth control valve 25 and the second end of the first passage 121. The second check valve 30 restricts the flow of fluid from the fifth control valve 25 to the first passage 121. This is configured to restrict the flow of fluid medium from the battery pack heat exchanger 3 to the fifth control valve 25, so that it does not flow to the second end of the first passage 121 of the regenerator 12, but flows to the first heat exchange path 001.

[0106] The end of the battery pack heat exchanger 3 away from the fifth control valve 25 is connected to the exhaust port 101 through the seventh control valve 27. This arrangement allows the battery pack heat exchanger 3 to be directly connected to the exhaust port 101 of the compressor 1, which is used when the battery pack needs to be heated. The seventh control valve 27 is a large-diameter throttling valve.

[0107] Through the above scheme, a flow path is formed from the exhaust port 101 of compressor 1 to the battery pack heat exchanger 3, then to the first heat exchanger 10, and finally to the return port 102 of compressor 1, for heating the battery pack. Specifically, the high-temperature and high-pressure gaseous refrigerant discharged from the exhaust port 101 of compressor 1 exchanges heat with the battery pack heat exchanger 3, then flows to the first end of the first heat exchanger 10, absorbs heat through the first heat exchanger 10, and returns to the return port 102 of compressor 1.

[0108] In some embodiments, the refrigerant subsystem 01 includes a battery pack heat exchanger 3, which is a heat exchange plate or a plate heat exchanger. In the latter case, the heat exchange plate is integrated with the battery pack, allowing the refrigerant to directly enter the battery pack for heat exchange. In the former case, the refrigerant subsystem exchanges heat with the coolant in the battery pack through the plate heat exchanger. The refrigerant subsystem 01 is integrated into a single module, significantly shortening the piping of the refrigerant subsystem 01, reducing refrigerant flow losses, and minimizing the size of the thermal management system. When the battery pack heat exchanger 3 is a heat exchange plate, all components except the separate heat exchange plate that needs to work with the power battery, including the refrigerant-related compressor 1, HVAC enclosure, various valves, tanks, and regenerator, are highly integrated. This integrated refrigerant subsystem 01 module can be located in the front compartment, expanding the passenger compartment's driving space. Furthermore, when the battery pack heat exchanger 3 is a plate heat exchanger, the entire refrigerant subsystem 01 can be integrated with this plate heat exchanger. The integrated refrigerant subsystem 01 is installed in a sealed safety enclosure to increase the overall system safety and prevent refrigerant leakage. To prevent refrigerant leakage, a sensor for detecting refrigerant leaks can be installed in the safety enclosure to monitor for leaks in real time. Additionally, the vehicle has a controller, and this sensor is connected to the controller. When the sensor detects a refrigerant leak, the controller controls an actuator to disconnect the air duct from the passenger compartment to ensure the safety of the occupants.

[0109] In some embodiments, the thermal management system further includes a refrigerant subsystem 01, which exchanges heat with the coolant subsystem 02 via a first heat exchanger 10. It is understood that the heat exchange between the refrigerant subsystem 01 and the coolant subsystem 02 improves thermal management efficiency.

[0110] In some embodiments, the first heat exchanger 10 is a plate heat exchanger that integrates condensation and evaporation. It is understood that when the refrigerant subsystem 01 is used for refrigeration, the first heat exchanger 10 acts as a condenser; when the refrigerant subsystem 01 is used for heating, the first heat exchanger 10 acts as an evaporator 7. This avoids the problem of using two components simultaneously in the prior art, improves the integration of the thermal management system, and reduces weight and volume.

[0111] In some implementations, please refer to Figure 1 and Figures 4-10 The coolant subsystem 02 includes a fifth heat exchange path 005, used to regulate the temperature of the powertrain 4 and to exchange heat with the refrigerant subsystem. It can be understood that the coolant subsystem 02 primarily dissipates heat from the powertrain 4 and collects the heat generated by the powertrain 4 to heat the refrigerant subsystem 01, or to dissipate heat transferred from the refrigerant subsystem 01.

[0112] The fifth heat exchange flow path 005 includes a powertrain 4 and a pump 5 that drives the flow of coolant. The first end of the powertrain 4 is connected to the third end of the first heat exchanger 10, and the second end is connected to the first end of the radiator 6. The second end of the radiator 6 is connected to the fourth end of the first heat exchanger 10, and the fourth end of the first heat exchanger 10 communicates with the third end. The pump 5 is located at any position capable of driving the medium to flow from within the first heat exchanger 10, such as on a pipe near the third or fourth end of the first heat exchanger 10. It is understood that the heat generated by the powertrain 4 can heat the medium in the first heat exchange flow path 001 through the first heat exchanger 10; alternatively, the medium in the first heat exchange flow path 001 can release heat to the medium in the fifth heat exchange flow path 005 through the first heat exchanger 10, and the heat can be dissipated through the radiator 6.

[0113] In some implementations, please refer to Figure 1 The fifth heat exchange path 005 includes a multi-port valve 28, which includes a first valve port 281, a second valve port 282, and a third valve port 283. The fourth end of the first heat exchanger 10 is connected to the second valve port 282 of the multi-port valve 28 via a pipeline. The second end of the power assembly 4 is connected to the first valve port 281 of the multi-port valve 28, and the first end of the radiator 6 is connected to the third valve port 283 of the multi-port valve 28. It can be understood that the multi-port valve 28 can control the connection or disconnection between any two valve ports, including the following media flow modes:

[0114] Circulation mode 1: The second valve port 282 is closed, and the first valve port 281 and the third valve port 283 are connected. The coolant forms a circulation loop through the powertrain 4, the first heat exchanger 10 and the radiator 6. At this time, the coolant can dissipate heat and can be used for cooling in the refrigerant subsystem 01.

[0115] Flow mode 2: Control three valve ports are closed, the second valve port 282 is connected to the first valve port 281, and the coolant forms a fluid loop through the powertrain 4 and the first heat exchanger 10 without passing through the radiator 6. At this time, the coolant can be heated and can be used for heating in the refrigerant subsystem 01.

[0116] Furthermore, the multi-way valve 28 also includes a fourth valve port 284, which is connected to the third end of the first heat exchanger 10 via a pipe. Therefore, the following coolant flow pattern can also be generated:

[0117] Circulation Mode 3: Control the second valve port 282 to close, and connect the first valve port 281 with the third valve port 283 and the fourth valve port 284. The coolant can be quickly cooled by the cooling fan and can be used for cooling in the refrigerant subsystem 01.

[0118] In this mode, the opening of the first valve port 281 and the fourth valve port 284 can be flexibly controlled to adjust the flow rate of coolant through the power assembly 4 and without passing through the power assembly 4. The coolant passing through the fourth valve port 284 does not pass through the power assembly 4, thereby improving the flow efficiency of the coolant. This can ensure the flow rate of the plate heat exchanger while reasonably distributing the flow rate through the power assembly 4 and reducing flow resistance.

[0119] Circulation Mode 4: Control the first valve port 281 and the second valve port 282 to close, and control the third valve port 283 and the fourth valve port 284 to open. The coolant can be quickly cooled by the cooling fan, and the coolant does not pass through the powertrain 4. It can be used for cooling in the refrigerant subsystem 01.

[0120] When the powertrain 4 does not require cooling, the coolant has high flow efficiency, low flow resistance, and faster heat dissipation in this mode.

[0121] Circulation Mode 5: Control the third valve port 283 and the fourth valve port 284 to close, and control the first valve port 281 and the second valve port 282 to open. The coolant forms a fluid loop through the powertrain 4 and the first heat exchanger 10, without passing through the radiator 6. At this time, the coolant can be heated and can be used for heating in the refrigerant subsystem 01, similar to circulation mode 2.

[0122] Flow Mode Six: The fourth valve port 284 is closed, while the first valve port 281, second valve port 282, and third valve port 283 are opened. A portion of the coolant is dissipated through the radiator 6, and the remaining portion flows directly back to the powertrain 4 through the second valve port 282. This mode is used when the powertrain 4 generates significant heat and there is still excess heat after heat exchange with the refrigerant subsystem 01. The excess heat is dissipated through the radiator 6, and this mode can be used for heating in the refrigerant subsystem 01.

[0123] Therefore, when the multi-port valve 28 has four ports, it is a four-way valve, which can adjust the coolant in the fifth heat exchange flow path 005 in various ways to meet the heat exchange requirements of the refrigerant subsystem 01.

[0124] The adjustment methods for the refrigerant subsystem 01 and the coolant subsystem 02 using the above technical solutions include the following:

[0125] Adjustment Method 1: Single Cooling Mode: Please refer to [link / reference] Figure 4 and Figure 10The system controls the second control valve 22, the fourth control valve 24, the sixth control valve 26, and the seventh control valve 27 to close, and controls the first control valve 21 and the third control valve 23 to open. The compressor 1 works to do work on the refrigerant, and the compressor 1 discharges high-temperature and high-pressure gaseous refrigerant, which flows to the first heat exchanger 10 through the first control valve 21. The first heat exchanger 10 exchanges heat between the high-temperature and high-pressure gaseous refrigerant and the fifth heat exchange flow path 005. At this time, the fifth heat exchange flow path 005 operates in flow mode three or flow mode four, condensing the high-temperature and high-pressure gaseous refrigerant into high-pressure and medium-temperature liquid or gas-liquid mixed refrigerant, which then flows into the gas-liquid separator 11 with liquid storage function. The liquid refrigerant flows from the gas-liquid separator 11 into the first passage 121, and then through the first passage 121 to the third control valve 23 and the evaporator 7. The refrigerated refrigerant flows back to the compressor 1 through the second passage 122. When the regenerator 12 and the gas-liquid separator 11 with liquid storage function are integrated into a liquid storage gas-liquid separation regenerator integrated unit 13, the refrigerant flows directly from the drain port of the liquid storage gas-liquid separation regenerator integrated unit 13 into the second heat exchange flow path 002.

[0126] Adjustment Method Two: Heating Mode: Please refer to [link / reference] Figure 5 and Figure 10 The system controls the first control valve 21, the third control valve 23, the fifth control valve 25, the sixth control valve 26, and the seventh control valve 27 to close, and controls the second control valve 22 and the fourth control valve 24 to open. The compressor 1 operates, performing work on the refrigerant. The high-temperature, high-pressure gaseous refrigerant discharged from the compressor 1 passes through the first condenser 8, where it gains heat and transforms into a medium-temperature, high-pressure mixed refrigerant. This mixed refrigerant then passes through the second control valve 22 (throttling valve) to reduce its pressure, forming a low-temperature, low-pressure refrigerant that enters the first heat exchanger 10. At this time, the fifth heat exchange path 005 operates in flow mode two, flow mode five, or flow mode six. The first heat exchanger 10 acts as the evaporator 7, where the refrigerant absorbs heat generated by the powertrain 4 in the coolant and evaporates into a mixed low-temperature, low-pressure refrigerant, which flows from the gas-liquid separator 11 to the compressor 1. When the regenerator 12 and the gas-liquid separator 11 with liquid storage function are integrated into a liquid storage gas-liquid separation regenerator integrated unit 13, the mixed low-temperature and low-pressure refrigerant flows from the exhaust port 101 of the liquid storage gas-liquid separation regenerator integrated unit 13 to the return port 102 of the compressor 1.

[0127] Adjustment Method 3: Air Conditioning Dehumidification and Battery Cooling Mode

[0128] Please see Figure 6 and Figure 10The system controls the first control valve 21, the fourth control valve 24, and the seventh control valve 27 to close, and controls the second control valve 22, the third control valve 23, the fifth control valve 25, and the sixth control valve 26 to open. The compressor 1 performs work, and the high-temperature, high-pressure refrigerant passes through the first condenser 8, which heats the refrigerant and delivers it to the passenger compartment. Because the heating demand is low in dehumidification mode, the first condenser 8 has a small heat dissipation, and the refrigerant flowing out of the first condenser 8 is still a high-temperature, high-pressure gaseous refrigerant. It then passes through the second control valve 22 (without throttling) to the first heat exchanger 10, which functions as a condenser. At this time, the fifth heat exchange flow path 005 operates in either flow mode one or flow mode four. The refrigerant is condensed into a medium-temperature, high-pressure saturated refrigerant and enters the gas-liquid separator 11, which acts as a liquid storage unit and regulates the refrigerant circulation volume. The refrigerant flows through the regenerator 12 to the third heat exchange path 003 to cool the battery, and controls the refrigerant to pass through the second heat exchange path 002. In the second heat exchange path 002, the temperature of the evaporator 7 decreases, and the blower of the evaporator 7 blows air over the surface of the evaporator 7. Since the temperature of the evaporator 7 is lower than the air temperature and dew point temperature, the gaseous water vapor in the air will be condensed into liquid water and separated from the air to form relatively dry air. Through the regulation of the hot and cold air damper, the cooled air is heated to a suitable temperature again through the first condenser 8 and enters the crew compartment to achieve the function of dehumidification.

[0129] Furthermore, when the regenerator 12 and the gas-liquid separator 11 with liquid storage function are integrated into a liquid storage gas-liquid separation regenerator integrated unit 13, the liquid refrigerant flows from the drain port of the liquid storage gas-liquid separation regenerator integrated unit 13 to the third heat exchange flow path 003.

[0130] Adjustment Method 4: Air Conditioning Heating and Battery Cooling Mode

[0131] Please see Figure 7 and Figure 10The system controls the first control valve 21, the third control valve 23, the fourth control valve 24, and the seventh control valve 27 to close, and controls the second control valve 22, the fifth control valve 25, and the sixth control valve 26 to open. The compressor 1 performs work, and the high-temperature, high-pressure refrigerant passes through the first condenser 8 for heating. The refrigerant then passes through the second control valve 22 to the first heat exchanger 10. The fifth heat exchange path 005 operates in either flow mode three or flow mode four. Excess heat can be stored in the coolant subsystem 02. The mixed refrigerant enters the gas-liquid separator 11, which acts as a liquid storage unit and regulates the refrigerant circulation. The refrigerant flows through the regenerator 12 to the third heat exchange path 003 to cool the battery and remove battery heat for further circulation in the compressor 1. When the regenerator 12 and the gas-liquid separator 11 with liquid storage function are integrated into a liquid storage gas-liquid separation regenerator integrated unit 13, the refrigerant flows directly from the drain port of the liquid storage gas-liquid separation regenerator integrated unit 13 into the third heat exchange flow path 003.

[0132] Adjustment Method 5: Air Conditioning Cooling and Battery Cooling Modes

[0133] Please see Figure 8 and Figure 10 The system controls the second control valve 22, the fourth control valve 24, and the seventh control valve 27 to close, and controls the first control valve 21, the third control valve 23, and the sixth control valve 26 to open. In regulation mode one, the refrigerant flowing through the regenerator 12 flows to the second heat exchange path 002 and the third heat exchange path 003 respectively, to form air conditioning cooling and battery cooling. The fifth heat exchange path 005 operates in flow mode three or flow mode four. When the regenerator 12 and the gas-liquid separator 11 with liquid storage function are integrated into a liquid storage gas-liquid separation regenerator integrated unit 13, the refrigerant flows directly from the drain port of the liquid storage gas-liquid separation regenerator integrated unit 13 into the second heat exchange path 002 and the third heat exchange path 003.

[0134] Adjustment Method Six: Air Conditioning Heating and Battery Pack Heating Mode

[0135] Please see Figure 9 and Figure 10The compressor controls the first control valve 21, the third control valve 23, and the sixth control valve 26 to close, and controls the second control valve 22, the fourth control valve 24, the fifth control valve 25, and the seventh control valve 27 to open. The compressor 1 then works on the refrigerant. One stream of refrigerant flows through the seventh control valve 27 to the battery pack heat exchanger 3, heating the battery pack. The battery pack heat exchanger 3 acts as a condenser, condensing the high-temperature, high-pressure refrigerant into a medium-temperature, high-pressure liquid refrigerant. This liquid refrigerant then passes through the fifth control valve 25 (throttle valve) to reduce its pressure, forming a low-temperature, low-pressure mixed refrigerant. This mixture then flows through the first check valve 29 to the... One heat exchanger 10; another medium, after being heated by the first condenser 8, becomes a low-temperature, low-pressure mixed refrigerant. After being throttled and depressurized by the second control valve 22 (throttle valve), it flows to the first heat exchanger 10 to absorb heat from the coolant subsystem 02. At this time, the fifth heat exchange flow path 005 operates in flow mode two, flow mode five, or flow mode six. The first heat exchanger 10 acts as an evaporator 7. The refrigerant absorbs the heat generated by the power assembly 4 in the coolant and then evaporates into a mixed low-temperature, low-pressure refrigerant, which flows from the gas-liquid separator 11 to the compressor 1. When the regenerator 12 and the gas-liquid separator 11 with liquid storage function are integrated into a liquid storage gas-liquid separation regenerator integrated unit 13, the mixed low-temperature, low-pressure refrigerant flows from the exhaust port 101 of the liquid storage gas-liquid separation regenerator integrated unit 13 to the return port 102 of the compressor 1.
