In existing technologies, the thermal management system of electric vehicles needs to meet the heating and cooling needs of the passenger compartment and powertrain, as well as the cooling and heating functions of the battery pack.

[0003] In the prior art, an electric vehicle thermal management system is disclosed to achieve effective temperature control between different areas inside the vehicle. An air conditioning unit system is installed in the passenger compartment, and a compressor, an air-cooled evaporator, and an air-cooled condenser are installed outside the passenger compartment, forming a first heat exchange medium circulation pipeline. The air conditioning unit system includes an air-cooled evaporator and an air-cooled condenser, with a damper corresponding to one side of the air-cooled condenser.

[0099] Furthermore, the technical features involved in the different embodiments of the present invention described below can be combined with each other as long as they do not conflict with each other.

[0100] Example 1

[0101] This embodiment provides an integrated valve 100, such as Figures 1-21 As shown, an air conditioning unit 105 with a liquid heat exchange medium is suitable for connection. The integrated valve 100 can be used to heat or cool components such as the air conditioning unit 105, the battery thermal management circuit, and the motor thermal management circuit. In this embodiment, the integrated valve 100 needs to be connected to an external cold source and a heat source to allow liquid heat exchange medium to flow into it. This liquid heat exchange medium is used to perform heating and cooling operations on different components.

[0102] It should be noted that in this embodiment, a third heat exchange component is provided in the battery thermal management circuit, which is thermally coupled with the battery. The third heat exchange component itself can be a structure that exchanges heat with the battery, such as a plate heat exchanger, or even a box structure that forms a certain contact area with the battery, with a liquid heat exchange medium flowing inside the box structure. Similarly, a fourth heat exchange component is provided in the motor thermal management circuit, which is thermally coupled with the motor. The structure of the fourth heat exchange component can be consistent with that of the third heat exchange component, as long as it can complete the heating and cooling operations of the motor.

[0103] Specifically, the liquid heat exchange medium is a liquid heat exchange medium capable of absorbing or releasing heat. After the liquid heat exchange medium completes the heating or cooling action at the cold or heat source location, it can exchange heat at the air conditioning unit 105, thereby enabling the air conditioning unit 105 to blow out cold or hot air. In this embodiment, the liquid heat exchange medium itself can be a common liquid heat exchange medium in the prior art that does not easily change volume, such as water mixed with refrigerant.

[0104] In this embodiment, the integrated valve 100 is adapted to control the liquid heat exchange medium in the thermal management system. The thermal management system includes a first thermal management subsystem and a second thermal management subsystem. The first thermal management subsystem includes a heat absorption component and a heat dissipation component.

[0105] In this embodiment, the heat dissipation component itself dissipates heat to the outside, causing its internal temperature to decrease. When the liquid heat exchange medium passes through the heat dissipation component, it will also cool down. Similarly, the heat absorption component itself absorbs heat to the outside, causing its internal temperature to increase. When the liquid heat exchange medium passes through the heat absorption component, it will heat up.

[0106] like Figure 2 As shown, the integrated valve 100 includes

[0107] The first interface 101 and the second interface 102 are specifically used to connect a first heat exchange component that is connected to the heat dissipation assembly via heat exchange. The first heat exchange component can cool the liquid heat exchange medium. Simultaneously, the first interface 101 can introduce external cooling medium into the integrated valve 100. The cooling medium flows into the integrated valve 100 through the first interface 101, and after completing the cooling operation on other structures, it flows out of the integrated valve 100 through the second interface 102.

[0108] In one implementation, the temperature of the liquid heat exchange medium introduced into the first interface 101 is between [0°C and 20°C].

[0109] The third interface 301 and the fourth interface 302 are used to connect a second heat exchange component that is connected to the heat absorption component in a heat exchange manner; at the same time, the third interface 301 and the second interface 302 are adapted to be connected to the heating medium. The heating medium flows into the integrated valve 100 through the third interface 301 and flows out of the integrated valve 100 through the third interface 301 after completing the heating operation of other structures.

[0110] In this embodiment, as one implementation method, the temperature of the liquid heat exchange medium through the third interface 301 is between [40°C and 80°C].

[0111] The fifth interface 111 and the sixth interface 112 are used to connect the second thermal management subsystem therebetween;

[0112] Specifically, such as Figure 2 From the perspective shown, the fifth interface 111 and the sixth interface 112 are located at the lower part of the integrated valve 100. The liquid heat exchange medium that flows into the integrated valve 100 through the first interface 101 and the third interface 301 will flow out to the outside of the integrated valve 100 through the fifth interface 111 and the sixth interface 112, and perform heat exchange with the battery, motor and other parts through the third heat exchange component or the fourth heat exchange component. After the heat exchange with the external structure is completed, the liquid heat exchange medium will flow back into the integrated valve 100 through the sixth interface 112, and flow out of the integrated valve 100 through the second interface 102 and the fourth interface 302, so that the liquid heat exchange medium can be heated or cooled again.

[0113] Furthermore, the fifth interface 111 and the sixth interface 112 are used to connect the second thermal management subsystem therebetween;

[0114] Specifically, as one implementation, the second thermal management subsystem itself can be an air conditioning unit 105 or a motor pipeline. The liquid heat exchange medium for heating or cooling can be introduced into the air conditioning unit 105 or the motor through the fifth interface 111 and the sixth interface 112, thereby realizing the heating or cooling operation of the air conditioning unit 105 or the motor and other structures.

[0115] Within the integrated valve 100, at least one valve is provided between the first interface 101 and the fifth interface 111, and at least one valve is provided between the second interface 102 and the sixth interface 112.

[0116] By setting the valve structure described above, the flow of the liquid heat exchange medium inside the integrated valve 100 can be controlled, thereby enabling cooling or heating operations for the second thermal management subsystem.

[0117] Furthermore, in this embodiment, it should be noted that the first interface 101, the second interface 102, the third interface 301, the fourth interface 302, the fifth interface 111, and the sixth interface 112 can be tangible, concrete pipe joints, or pipe structures that require adapters or other structures to achieve waterway connectivity. Therefore, the main function of the first interface 101 and other structures is to complete the entry and exit of the liquid heat exchange medium. Thus, any structure that can achieve the above function can be used as a different interface structure for the first interface 101 and the second interface 102 in this embodiment.

[0118] The integrated valve 100 further includes: a first pipeline 103 connected to the first interface 101 and the fifth interface 111; and a second pipeline 104 connected to the sixth interface 112 and the second interface 102. Through the above-described pipeline configuration, cooling operations on the second thermal management subsystem can be achieved.

[0119] In this embodiment, as Figure 3 As shown, it further includes: an eleventh interface and a twelfth interface, wherein the fifth interface 111 and the sixth interface 112 are used to connect the third thermal management subsystem therebetween, the eleventh interface is connected to the first interface 101, and the twelfth interface is connected to the second interface 102; a third pipe 106, which is connected to the first interface 101 and the eleventh interface; and a fourth pipe 107, which is connected to the second interface 102 and the twelfth interface.

[0120] The above configuration allows for cooling of the third thermal management subsystem. This third thermal management subsystem can be an air conditioning unit 105; therefore, the above structure enables temperature control of both air conditioning units 105.

[0121] Furthermore, a second three-way valve 202 is provided on the first pipeline 103. The second three-way valve 202 has a first outlet and a second outlet. The first outlet is connected to one of the fifth interfaces 111. A third pipeline 106 is provided on the second outlet. The third pipeline 106 is adapted to connect to the eleventh interface.

[0122] Specifically, such as Figure 4 As shown, the first outlet of the second three-way valve 202 is positioned downwards, and the second outlet of the second three-way valve 202 is positioned to the right. Specifically, as... Figure 4 As shown, the fifth interface 111 and the eleventh interface are located on both sides of the two air conditioning units 105.

[0123] Furthermore, after the cooling operation of the air conditioning unit 105 is completed, the liquid heat exchange medium needs to be returned to the integrated valve 100. In this embodiment, a second pipe 104 and a fourth pipe 107 are respectively provided, which are connected to the second interface 102 and the sixth interface 112 respectively.

[0124] In the above-described embodiment, each of the two air conditioning units 105 is provided with an independent cooling medium inflow pipe and a fifth pipe 108.

[0125] It should be noted that the first pipe 103, the second pipe 104, the third pipe 106, and the fourth pipe 107 can be tubular structures of a certain length, such as plastic rigid pipes, plastic flexible pipes, or rubber pipes, which are common tubular structures in the prior art. Correspondingly, the sixth interface 112 and the twelfth interface are combined into a return interface, which is connected to the fifth pipe 108.

[0126] Furthermore, in this embodiment, by adjusting the structure of the second three-way valve 202, more pipelines can be branched out, thereby enabling temperature control for more thermal management subsystems. The specific structure is similar to the structure above and is not subject to excessive limitations.

[0127] To better illustrate the flow path of the liquid heat exchange medium inside the integrated valve 100, the thickness of the lines is used to represent the flow path of the liquid heat exchange medium. Thicker lines indicate that liquid heat exchange medium flows through the interior, while thinner lines indicate that no liquid heat exchange medium flows through the interior.

[0128] The following describes the structure and operating mode of the integrated valve 100 in its cooling function:

[0129] Cooling Mode 1: Cooling operation for the area where air conditioning unit 105 is located. The working process is as follows:

[0130] like Figure 2 and Figure 3 As shown, the area where the air conditioning unit 105 is located can be the passenger compartment or other areas requiring cooling. Cooling liquid heat exchange medium flowing out through the heat dissipation components is introduced into the first air conditioning unit 1051 through the first pipe 103. The air conditioning unit 105 is equipped with a liquid heat exchange medium heat exchange section. After cooling water is introduced into the liquid heat exchange medium heat exchange section, its temperature decreases. Ventilation of the liquid heat exchange medium heat exchange section can then cool the passenger compartment and other areas. A second three-way valve 202 is installed on the first pipe 103 to divert the liquid heat exchange medium. Liquid heat exchange medium flowing out through the second outlet of the second three-way valve 202 enters the second air conditioning unit 1052, thereby cooling the second air conditioning unit 1052. One stream flows back to the second interface 102 through the second pipe 104; another stream enters the second air conditioning unit 1052 and then flows back to the second interface 102 through the fourth pipe 107.

[0131] It should be noted that, in this embodiment, the liquid heat exchange medium can flow into the integrated valve 100 through the first interface 101, then into the first air conditioning unit 1051 through the fifth interface 111, and then back into the integrated valve 100 through the sixth interface 112, and finally out of the integrated valve 100 through the second interface 102. As a variation, when the first air conditioning unit 1051 is connected to the first interface 101 and the second interface 102, the liquid heat exchange medium can also flow into the integrated valve 100 through the fifth interface 111, then into the first air conditioning unit 1051 through the first interface 101, further back into the integrated valve 100 through the second interface 102, and then out of the integrated valve 100 through the sixth interface 112.

[0132] like Figure 3 As shown, in one embodiment, the first air conditioning unit 1051 corresponds to the driver's seat in the cockpit, and the second air conditioning unit 1052 corresponds to the passenger seat in the cockpit. By controlling the second three-way valve 202, cooling operations can be performed simultaneously on both the driver's and passenger's seats.

[0133] Furthermore, in the integrated valve 100 provided in this embodiment, the second pipeline 104 and the fourth pipeline 107 converge to form a fifth pipeline 108, which is connected to the second interface 102. By merging the two return pipelines as described above, the space occupied by the integrated valve 100 itself can be effectively reduced, improving the air conditioning system's overall neatness.

[0134] Furthermore, in the integrated valve 100 provided in this embodiment, the opening degrees of the first outlet and the second outlet of the second three-way valve 202 are adjustable. By adjusting the opening degrees of the first outlet and the second outlet, the flow rate suitable for the first air conditioning unit 1051 and the second air conditioning unit 1052 can be adjusted. Through the above-described configuration, the flow rate of the liquid heat exchange medium flowing out from the first outlet and the second outlet can be effectively controlled, thereby allowing for precise adjustment of the cooling effect of the first air conditioning unit 1051 and the second air conditioning unit 1052.

[0135] Specifically, the flow rates at the first and second outlets of the second three-way valve 202 are proportionally distributed. For example, if the flow rate at the first outlet accounts for 10%, then the flow rate at the second outlet accounts for 90%. In this case, the cooling effect of the second air conditioning unit 1052 corresponding to the second outlet will be better. The specific working process is described below:

[0136] Cooling Mode 2: Performs cooling operations of varying degrees on multiple areas. The working process is as follows:

[0137] The system obtains the required temperatures for the areas where the first air conditioning unit 1051 and the second air conditioning unit 1052 are located. Based on the temperature requirements of the two different areas, the opening degrees of the first and second outlets of the second three-way valve 202 are adjusted. In cooling mode, the lower the required temperature, the larger the corresponding opening degree. For example, if the temperature requirement of the first air conditioning unit 1051 is 20℃ and the temperature requirement of the second air conditioning unit 1052 is 25℃, then the opening degree of the first outlet of the second three-way valve 202 is controlled to be 45%, and the opening degree of the second outlet of the second three-way valve 202 is controlled to be 55%.

[0138] like Figure 4 As shown, in addition to cooling the two air conditioning units 105, this embodiment can also cool other external structures. To introduce the cooling liquid heat exchange medium to the outside, the integrated valve 100 further includes:

[0139] The seventh interface 113 is connected to the first interface 101;

[0140] The eighth interface 114 is connected to the second interface 102, and the seventh interface 113 and the eighth interface 114 are adapted to connect a third heat exchange component that is coupled to the battery for heat exchange.

[0141] In this embodiment, to introduce the cooled liquid heat exchange medium into the seventh interface 113, a pipeline can be directly connected between the first interface 101 and the seventh interface 113. As a variation, the integrated valve 100 provided in this embodiment further includes: a first three-way valve 201, disposed on the first pipeline 103 and located between the second three-way valve 202 and the first interface 101. The first three-way valve 201 is provided with a first outlet and a second outlet. The first outlet is connected to the inlet of the second three-way valve 202, and the second outlet is adapted to connect to the sixth pipeline 109.

[0142] Specifically, such as Figure 4 From the perspective shown, the first outlet faces downwards, and the second outlet faces to the right. The first three-way valve 201 is located above the second three-way valve 202. The external liquid heat exchange medium first flows to the first three-way valve 201, then flows out through the first outlet and enters the second three-way valve 202. The liquid heat exchange medium (such as cooling water) flowing out through the second outlet enters the sixth pipeline 109, thereby cooling other pipelines.

[0143] like Figure 5 and Figure 6 As shown, in order to reintroduce the liquid heat exchange medium that has completed the cooling work into the integrated valve 100, a seventh pipe 110 is also provided inside the integrated valve 100, one end of which is connected to the eighth interface 114 and the other end of which is connected to the second interface 102.

[0144] Specifically, after the liquid heat exchange medium completes the cooling operation on other loops, the heated liquid heat exchange medium will flow back to the integrated valve 100 through the seventh pipe 110, and further flow to the second interface 102. The specific working process is described below:

[0145] Cooling Mode 3: Simultaneously cools the air conditioning unit 105 and other external pipes. The working process is as follows:

[0146] The first and second outlets of the first three-way valve 201 are opened, and the cooling liquid heat exchange medium flows downwards into the second three-way valve 202. The liquid heat exchange medium entering the second three-way valve 202 can be divided into two modes: the first mode flows out only through the first or second outlet of the second three-way valve 202 to cool one of the first air conditioning unit 1051 and the second air conditioning unit 1052; the second mode flows out through both the first and second outlets simultaneously to cool both the first air conditioning unit 1051 and the second air conditioning unit 1052.

[0147] Then, the cooled liquid heat exchange medium flowing out from the second outlet of the second three-way valve 202 flows into the sixth pipe 109. The sixth pipe 109 can be connected to the battery thermal management circuit, the motor thermal management circuit, etc. After the cooling operation is completed, the relatively high-temperature liquid heat exchange medium formed will flow back to the integrated valve 100 through the seventh pipe 110, and flow to the heat dissipation component through the second interface 102, where it will be cooled again.

[0148] like Figure 5 As shown, the integrated valve 100 provided in this embodiment further includes a fifth three-way valve 205, which is disposed on the second pipeline 104, and the inlet of the fifth three-way valve 205 is adapted to connect to the seventh pipeline 110.

[0149] Specifically, such as Figure 5 From the perspective shown, the fifth three-way valve 205 has two inlets: a second inlet facing to the right and a first inlet facing downwards. The second inlet connects to the seventh pipe 110, and the first inlet connects to the second pipe 104 (the fifth pipe 108). Liquid heat exchange medium flowing from below and to the right converges at the fifth three-way valve 205 and flows from its outlet to the second interface 102. By merging the seventh pipe 110 and the second pipe 104 through the fifth three-way valve 205, the piping is simplified, which helps improve space utilization efficiency.

[0150] Furthermore, in the integrated valve 100 provided in this embodiment, the opening degrees of the first outlet and the second outlet of the first three-way valve 201 are adjustable. By adjusting the opening degrees of the first outlet and the second outlet, the flow rate entering the air conditioning unit 105 and the sixth pipeline 109 can be regulated. Through the above-described configuration, different proportions of control can be achieved for the air conditioning unit 105, the battery thermal management circuit, and the motor thermal management circuit in cooling mode. For specific control logic, please refer to Mode 3.

[0151] The integrated valve 100 provided in this embodiment, such as Figure 6 As shown, it also includes a one-way shut-off valve 207, with both ends connected to the sixth pipeline 109 and the seventh pipeline 110. When the one-way shut-off valve 207 is opened, the second outlet of the first three-way valve 201 and the second outlet of the fifth three-way valve 205 are closed. At this time, a closed loop will be formed between the sixth pipeline 109, the battery thermal management circuit connected to the integrated valve 100, and the seventh pipeline 110.

[0152] The following describes the structure and operating mode of the integrated valve 100 in the heating function:

[0153] like Figures 9-12 As shown, the integrated valve 100 provided in this embodiment further includes:

[0154] The third interface 301 and the fourth interface 302 are adapted to be connected to the liquid heat exchange medium obtained after being heated by the heat absorption component.

[0155] Specifically, the third interface 301 is used to introduce an external liquid heat exchange medium. After the liquid heat exchange medium completes the heating operation of the relevant structure, the cooled liquid heat exchange medium will flow out from the integrated valve 100 through the fourth interface 302. In this embodiment, the temperature of the liquid heat exchange medium can be adjusted according to different operating conditions. As one implementation method, the temperature range of the liquid heat exchange medium itself is [40℃-80℃].

[0156] Similarly, the third interface 301 and the fourth interface 302 are suitable for the parts that are connected to the external liquid heat exchange medium. They can be specific pipe joints, pipe structures, or water circuits connected through adapters, etc.

[0157] like Figure 10 As shown, the eighth pipe 303 is connected at one end to the third interface 301 and at the other end to the water inlet of the first air conditioning unit 1051.

[0158] like Figure 10As shown, the ninth pipe 304 is connected at one end to the fourth interface 302, and the other end is adapted to connect to the outlet of the first air conditioning unit 1051. Specifically, the eighth pipe 303 and the eleventh pipe 306 are used to transport external liquid heat exchange medium into the air conditioning unit 105, where heat exchange operations take place. These pipes can be tubular structures of a certain length, such as rigid plastic pipes, flexible plastic pipes, or rubber pipes—common tubular structures in the prior art.

[0159] The liquid heat exchange medium enters the integrated valve 100 through the third port 301, flows to the first air conditioning unit 1051 through the eighth pipe 303, performs heat exchange inside the first air conditioning unit 1051, and then flows back to the fourth port 302 through the ninth pipe 304 to complete the cycle.

[0160] Furthermore, in the integrated valve 100 provided in this embodiment, the eighth pipeline 303 is connected to the first pipeline 103. Through the above arrangement, two originally independent pipelines are first intersected, and then the liquid heat exchange medium for heating and cooling is simultaneously transported through a single pipeline. This reduces the number of interfaces on the air conditioning unit 105, thereby improving the overall simplification of the equipment and reducing the number of components.

[0161] In this embodiment, in order to achieve the heating operation of the first air conditioning unit 1051 and the second air conditioning unit 1052, two independent pipes can be simultaneously led out from the third interface 301; as a variation, such as Figure 11 As shown, the integrated valve 100 provided in this embodiment further includes:

[0162] like Figure 11 As shown, the fourth three-way valve 204 is installed on the eighth pipeline 303. The fourth three-way valve 204 includes a first outlet and a second outlet. The first outlet of the fourth three-way valve 204 is connected to the first pipeline 103. The second outlet of the fourth three-way valve 204 is connected to a tenth pipeline 305. One end of the tenth pipeline 305 is adapted to be connected to the water inlet of the second air conditioning unit 1052.

[0163] like Figure 14 As shown, the eleventh pipe 306 is connected at one end to the twelfth interface and at the other end to the fourth interface 302.

[0164] Specifically, such as Figure 12From the perspective shown, the first outlet of the fourth three-way valve 204 extends to the left, and the second outlet extends downward. Both the inlet and the first outlet of the fourth three-way valve 204 are located on the eighth pipe 303. By setting the fourth three-way valve 204, the liquid heat exchange medium of the third interface 301 can be split into two branches, thereby simultaneously providing liquid heat exchange medium to the first air conditioning unit 1051 and the second air conditioning unit 1052 for heating operation, thus greatly improving the structural compactness of the entire integrated valve 100.

[0165] Furthermore, the ninth pipe 304 and the eleventh pipe 306 are combined into a heating medium return pipe, which is connected to the return interface. This simplifies the structure.

[0166] Heating Mode 1: Heating operation is performed on the area where the first air conditioning unit 1051 and the second air conditioning unit 1052 are located. The working process is as follows:

[0167] The first and second outlets of the control three-way valve 204 are opened, and the liquid heat exchange medium flowing in through the third interface 301 is divided into two paths. One path flows through the eighth pipe 303 into the first air conditioning unit 1051, and the other path flows out through the second outlet of the control three-way valve 204 and into the tenth pipe 305. The tenth pipe 305 carries the liquid heat exchange medium into the second air conditioning unit 1052. The liquid heat exchange medium flowing out of the second air conditioning unit 1052 enters the second hot water return pipe, and then flows further to the fourth interface 302, where it is reheated by the heat source to repeatedly return to the integrated valve 100.

[0168] In this embodiment, to further improve the compactness of the structure, the ninth pipe 304 and the eleventh pipe 306 are combined into a liquid heat exchange medium return pipe. Through the above arrangement, the two pipes can be combined, requiring only one corresponding interface to export the liquid heat exchange medium after heating to the fourth interface 302, thereby simplifying the structure and improving space utilization efficiency.

[0169] Furthermore, in this embodiment, the integrated valve 100, as one implementation, allows the liquid heat exchange medium return pipeline and the fifth pipeline 108 to be set up independently; as another implementation, the liquid heat exchange medium return pipeline and the fifth pipeline 108 are combined into a single medium return pipeline. In this case, to simultaneously guide the heating and cooling of the liquid heat exchange medium on the same medium return pipeline, and to direct the heating and cooling liquid heat exchange medium to different locations, a sixth three-way valve 206 is provided on the medium return pipeline. The sixth three-way valve 206 includes a first outlet and a second outlet. The first outlet of the sixth three-way valve 206 is connected to the second interface 102, and the second outlet of the sixth three-way valve 206 is connected to the fourth interface 302. By merging two independent pipelines through the sixth three-way valve 206, the internal structure is further simplified.

[0170] The working process of the sixth three-way valve 206 is as follows:

[0171] When the air conditioning unit 105 needs to be cooled, the first outlet of the sixth three-way valve 206 is opened and the second outlet of the sixth three-way valve 206 is closed. At this time, the water flowing out of the fifth pipe 108 flows directly to the second interface 102 through the sixth three-way valve 206. When the air conditioning unit 105 needs to be heated, the first outlet of the sixth three-way valve 206 is closed and the second outlet of the sixth three-way valve 206 is opened. At this time, the water flowing out of the hot water return pipe flows directly to the fourth interface 302 through the second outlet of the sixth three-way valve 206.

[0172] Furthermore, such as Figure 13 As shown, when heating is required for structures other than the second thermal management subsystem, this embodiment additionally includes:

[0173] The ninth interface 310 is connected to the third interface 301. The liquid heat exchange medium flowing in through the third interface 301 flows out through the ninth interface 310 to the outside of the integrated valve 100. A twelfth pipe 307 is provided between the third interface 301 and the ninth interface 310.

[0174] The tenth interface 311 is connected to the ninth interface 310. A thirteenth pipe 308 is provided between the tenth interface 311 and the fourth interface 302. The ninth interface 310 and the tenth interface 311 are suitable for connecting a motor thermal management circuit.

[0175] Furthermore, the twelfth pipe 307 and the first pipe 103 can be connected by two independent pipe structures. In another embodiment, a third three-way valve 203 is also provided inside the integrated valve 100, located on the eighth pipe 303, and includes a first outlet and a second outlet. The first outlet of the third three-way valve 203 is connected to the first pipe 103, and the second outlet of the third three-way valve 203 is connected to the twelfth pipe 307. The twelfth pipe 307 is suitable for connecting one or more of the battery pack 501, powertrain 502, and radiator 503.

[0176] The thirteenth pipe 308 is adapted to connect one or more of the battery pack 501, powertrain 502 and radiator 503, and one end of the thirteenth pipe 308 is connected to the fourth interface 302.

[0177] Specifically, by setting a third three-way valve 203, the hot water flowing out through the fourth interface 302 is divided into two paths. One path flows through the first pipe 103 to the air conditioning unit 105, and the other path flows through the twelfth pipe 307 to the outside of the integrated valve 100, thereby heating the external structure of the integrated valve 100. In this embodiment, the twelfth pipe 307 and the thirteenth pipe 308 are used to connect with external pipes and to heat the battery pack 501, powertrain 502, etc. on the external pipes.

[0178] Furthermore, in this embodiment, the hot water flowing out from the second outlet of the sixth three-way valve 206 can be directly connected to the fourth interface 302; as a variation, such as Figure 14 As shown, a fourteenth pipe 309 can be connected between the second outlet of the sixth three-way valve 206 and the thirteenth pipe 308, thereby further simplifying the piping and avoiding excessive piping inside the integrated valve 100. At this time, a shut-off valve 208 is installed on the thirteenth pipe 308, which is suitable for controlling the on / off state of the thirteenth pipe 308.

[0179] Specifically, the working process of the shut-off valve 208 is as follows:

[0180] When it is necessary to heat the air conditioning unit 105 and the external pipeline at the same time, the first and second outlets of the third three-way valve 203 are opened, and the shut-off valve 208 is opened at the same time. The liquid heat exchange medium flowing out from the second outlet of the third three-way valve 203 flows into the thirteenth pipeline 308 after completing heat exchange with the battery, motor, etc. Since the shut-off valve 208 is open, the water in the thirteenth pipeline 308 can flow directly to the fourth interface 302 position.

[0181] When only heating is needed for the air conditioning unit 105, the first outlet of the third three-way valve 203 is opened, and the second outlet of the third three-way valve 203 is closed. The liquid heat exchange medium flows out of the air conditioning unit 105 and enters the fourteenth pipe 309 through the sixth three-way valve 206. When the liquid heat exchange medium in the fourteenth pipe 309 enters the thirteenth pipe 308, it can flow simultaneously towards the fourth interface 302 and the outside of the integrated valve 100. Figure 14 As shown, the liquid heat exchange medium can flow upwards or downwards simultaneously. When this occurs, the control shut-off valve 208 closes, blocking the flow of the liquid heat exchange medium to the outside of the integrated valve 100. This ensures that the liquid heat exchange medium flows only towards the fourth port 302.

[0182] Furthermore, the shut-off valve 208 controls the on / off state of the thirteenth pipeline 308 by switching it on and off. In one implementation, when the shut-off valve 208 is not energized, it will remain normally open, thus ensuring that the thirteenth pipeline 308 remains unobstructed. In another implementation, the shut-off valve 208 can also be selected to remain normally open when it is not energized.

[0183] In this embodiment, the integrated valve 100 can be equipped with a housing, and the relevant pipelines and three-way valve can be integrated into the housing. This arrangement can improve the neatness of the entire structure and facilitate the assembly operation of the integrated valve 100 in the later stage.

[0184] In this embodiment, multiple three-way valves, including the first three-way valve 201, can use electromagnetic structures to control the opening and closing of their inlets and outlets. The three-way valves themselves use conventional interfaces in the prior art, with electromagnetic interfaces set at the inlet and outlet, thereby enabling independent opening and closing operations of the inlet and outlet.

[0185] Example 2

[0186] This embodiment provides a thermal management module for a vehicle, including:

[0187] The first heat exchange medium circulation pipeline includes a compressor 401, an evaporator 402, a condenser 403 and an expansion valve 404 connected in series, and a first circulation pump 405 is provided on the first heat exchange medium circulation pipeline.

[0188] The overall working principle of the first heat exchange medium circulation pipeline can be considered as follows: gaseous refrigerant enters compressor 401, and after being compressed by compressor 401, it is transformed into a refrigerant with increased temperature and pressure. The refrigerant with increased temperature and pressure undergoes heat exchange at condenser 403, becoming a medium-temperature and medium-pressure refrigerant. The refrigerant passes through expansion valve 404, where its pressure and temperature are further reduced, potentially becoming a gas-liquid two-phase mixture. After heat exchange in evaporator 402, it becomes gaseous refrigerant again and returns to compressor 401, thus completing one cycle. Simultaneously, the first circulation pump 405 assists in the flow of the refrigerant within the first heat exchange medium circulation pipeline.

[0189] Furthermore, a refrigerant needs to flow in the first heat exchange medium circulation pipeline. In this embodiment, the refrigerant itself can be selected from media commonly used in the prior art, including but not limited to CHF2CHF2 (tetrafluoroethane), R744 (carbon dioxide), R718 (water), R290 (propane), R717 (ammonia), R410a (a mixture of 50% difluoromethane and 50% pentafluoroethane), R32 (difluoromethane), R12 (CCl2F2), and other commonly used refrigerants in the prior art, or any combination of two or more of these refrigerants. Simultaneously, to achieve stable operation in cooling environments, antifreeze or other substances can be injected into the refrigerant to improve its antifreeze performance.

[0190] The second heat exchange medium circulation pipeline includes a first flow path 406, which is located at the evaporator 402. The first flow path 406 is adapted to pass a cooling liquid heat exchange medium. The evaporator 402 is used to cool the liquid heat exchange medium. A second circulation pump 408 is provided on the second heat exchange medium circulation pipeline.

[0191] And / or,

[0192] A second flow path 407 is provided at the location of the condenser 403. A liquid heat exchange medium is adapted to be introduced into the second flow path 407, and the condenser 403 is adapted to heat the liquid heat exchange medium.

[0193] The evaporator 402 provides its own cooling environment. When the liquid heat exchange medium in the first flow path 406 flows to the evaporator 402, the evaporator 402 will cool the liquid heat exchange medium. The condenser 403 provides its own heating environment. When the liquid heat exchange medium in the second flow path 407 flows to the condenser 403, the condenser 403 will heat the liquid heat exchange medium.

[0194] By setting a second circulation pump 408, the water in the second heat exchange medium circulation pipeline can be driven. The second circulation pump 408 itself can be set on the first flow path 406 or the second flow path 407, as long as it can complete the driving action of the liquid heat exchange medium.

[0195] The integrated valve 100 provided in Example 1;

[0196] The integrated valve 100 has multiple interfaces for connecting to the twelfth pipe 307, the thirteenth pipe 308, the first pipe 103, and the second pipe 104, thereby enabling the extraction and return of the liquid heat exchange medium.

[0197] The thermal management module provided in this embodiment integrates a first heat exchange medium circulation pipeline and a second heat exchange medium circulation pipeline. Through these two pipelines, a liquid heat exchange medium with a certain temperature can be provided to the integrated valve 100. At the same time, by connecting with the integrated valve 100, the integrated valve 100 can distribute the external heating or cooling liquid heat exchange medium, thereby effectively heating and cooling different structures.

[0198] Furthermore, such as Figure 17 As shown, in this embodiment, a gas-liquid separator 412 is provided on the first heat exchange medium circulation pipeline between the compressor 401 and the expansion valve 404. One end of the hot gas bypass pipeline is provided between the compressor 401 and the expansion valve 404, and the other end acts on the gas-liquid separator 412. A bypass expansion valve 410 is provided on the hot gas bypass pipeline.

[0199] The main function of the gas-liquid separator is to protect the compressor 401 when the refrigerant liquid returns after startup, operation, or defrosting. This protection is mainly achieved by separating and storing the refrigerant liquid in the return line. The gas-liquid separator 412 provides additional internal volume to the low-pressure side of the system, which can temporarily store excess refrigerant liquid and also prevent excess refrigerant from flowing into the crankcase of the compressor 401 and causing oil dilution.

[0200] Furthermore, such as Figure 19 As shown, in this embodiment, an auxiliary heating module 411 is provided on the second flow path 407. The auxiliary heating module 411 is adapted to be activated when the ambient temperature and / or the liquid heat exchange medium is lower than a preset temperature.

[0201] Specifically, in this embodiment, the auxiliary heating module 411 can be an HVH (high voltage heater), which can be used to assist in heating the second flow path 407, thereby rapidly heating the liquid heat exchange medium and achieving the purpose of rapidly heating the passenger compartment and battery structures.

[0202] Furthermore, to achieve heat exchange between the first flow path 406 and the second flow path 407, a first plate heat exchanger is provided on the first flow path 406 at the location corresponding to the evaporator 402; and / or, a second plate heat exchanger is provided on the second flow path 407 at the location corresponding to the condenser 403. By employing plate heat exchange, the heat exchange efficiency is effectively improved.

[0203] Example 3

[0204] This embodiment provides a thermal management system for a vehicle, including:

[0205] The thermal management module in Example 2;

[0206] The air conditioning unit 105 is connected to the fifth interface 111 and the sixth interface 112 of the thermal management module; and / or, the air conditioning unit 105 is connected to the eleventh interface and the twelfth interface of the integrated valve 100.

[0207] The air conditioning unit 105 is equipped with a liquid heat exchange medium heat exchange section, which is connected to the first flow path 406 and the second flow path 407 of the thermal management module. The air conditioning unit 105 is correspondingly arranged with the passenger cabin.

[0208] Specifically, in this embodiment, the liquid heat exchange medium heat exchange section itself can exchange heat with the liquid heat exchange medium when it is introduced.

[0209] The second integrated valve 600 has several interfaces on it;

[0210] The battery thermal management circuit, the motor thermal management circuit, and the radiator 503 circuit are respectively set on the interface of the second integrated valve 600. The radiator 503 circuit is equipped with a radiator 503. The battery thermal management circuit, the motor thermal management circuit, and the radiator 503 circuit can be independently or connected in series through the second integrated valve 600.

[0211] Specifically, a third thermal management subsystem is provided on the battery thermal management circuit, and a fourth thermal management subsystem is provided on the motor thermal management circuit. The third thermal management subsystem is configured in correspondence with the battery pack 501, and the fourth thermal management subsystem is configured in correspondence with the motor.

[0212] Multiple motors are installed inside the vehicle. These motors can be front-drive motors, rear-drive motors, or both. A radiator 503 structure is installed on the radiator 503 circuit. The radiator 503 itself has a large surface area to increase the heat dissipation area, thereby facilitating subsequent convection with the air and achieving the effect of heating or cooling.

[0213] In this embodiment, the battery pack 501 is the core energy source of the vehicle, providing driving power for the entire vehicle. The battery pack 501 in this embodiment adopts a common battery pack 501 found in the prior art. As one implementation method, it can use lithium iron phosphate batteries, ternary lithium batteries, cobalt-free batteries, lithium titanate batteries, or lithium manganese oxide batteries. The battery pack 501 generally includes a positive electrode, a negative electrode, an electrolyte, a separator, a battery casing, and multiple battery cells. Furthermore, to facilitate power control, a battery management system is also integrated.

[0214] The fifteenth conduit 701 is connected to the seventh interface 113 and the eighth interface 114;

[0215] The sixteenth pipe 702 is connected to the second flow path 407, and the fifteenth pipe 701 and the sixteenth pipe 702 are respectively connected to the first integrated valve 100 and the second integrated valve 600.

[0216] Specifically, such as Figure 19 As shown, the fifteenth pipe 701 and the sixteenth pipe 702 are located in the middle of the integrated valve 100 and the second integrated valve 600, respectively. The liquid heat exchange medium flows through the integrated valve 100 to the fifteenth pipe 701 and the sixteenth pipe 702, and then further enters the second integrated valve 600. After completing heat exchange with the battery thermal management circuit, the motor thermal management circuit and the radiator 503 circuit, it flows back to the second integrated valve 600, and then flows back to the integrated valve 100 again through the fifteenth pipe 701 and the sixteenth pipe 702.

[0217] In this embodiment, in order to improve the heat dissipation effect of the heat sink 503 itself, a cooling fan 504 is also included, which is provided corresponding to the heat sink 503.

[0218] Furthermore, in this embodiment, the structure of the second integrated valve 600 itself is not limited, as long as it can achieve series connection or independent conduction between different water channels. As one implementation method, in this embodiment, the second integrated valve 600 is an eight-way valve. The eight-way valve itself has nine ports, which are used to connect to external pipelines. Inside the eight-way valve, the conduction of the internal flow channels can be controlled, and up to eight different connection structures can be formed.

[0219] In the prior art, in order to simultaneously heat up or cool down the passenger compartment and structures such as batteries and motors, an air conditioning unit 105 system is usually installed in the passenger compartment. A compressor 401, an air-cooled evaporator 402, and an air-cooled condenser 403 are installed outside the passenger compartment to form a first heat exchange medium circulation pipeline. The air conditioning unit 105 system includes an air-cooled evaporator 402 and an air-cooled condenser 403. A damper is provided on one side of the air-cooled condenser 403. The air-cooled evaporator 402 can cool the passenger compartment, and the air-cooled condenser 403 can heat the passenger compartment. When the damper is opened, the air-cooled condenser 403 can exchange heat. Meanwhile, a water-cooled evaporator 402 and a water-cooled condenser 403 are connected in series on the first heat exchange medium circulation pipeline outside the passenger compartment. Water circulation pipelines are connected to the water-cooled condenser 403 and the water-cooled evaporator 402 respectively. The water-cooled condenser 403 and the water-cooled evaporator 402 heat or cool the water in the water circulation pipeline connected to them. The water obtained after heating or cooling will further act on the battery pack 501 or powertrain 502 of the electric vehicle to achieve heating or cooling operations.

[0220] In this embodiment, a first heat exchange medium circulation pipeline can simultaneously perform cooling and heating operations on structures such as the passenger compartment, battery, and motor, which can effectively reduce the space occupied and the number of structures involved.

[0221] Furthermore, in this embodiment, a water tank 505 is also provided on the battery thermal management circuit and / or the motor thermal management circuit. Water can be injected into the water tank 505, and the water is used to form a heating or liquid heat exchange medium.

[0222] Example 4

[0223] In this embodiment, the thermal management system of Embodiment 3 is used to provide a thermal management system control method for a vehicle.

[0224] like Figure 2 As shown, this embodiment provides a cooling mode for the first air conditioning unit 1051 and / or the second air conditioning unit 1052: This mode is used to cool the passenger cabin during summer or other external heating conditions, when the battery operates at low power and does not require heat dissipation. It includes the following steps:

[0225] The number of air conditioning units 105 is two, including a first air conditioning unit 1051 and a second air conditioning unit 1052, and the control method includes the following steps:

[0226] Control the opening of one of the first and second outlets of the first three-way valve 201;

[0227] The liquid heat exchange medium in the first flow path 406 is controlled to enter one of the air conditioning units 105 through the first pipe 103, and then return to the second interface 102 through the second pipe 104;

[0228] The liquid heat exchange medium in the third pipeline 106 is controlled to enter the second air conditioning unit 1052 through the third pipeline 106 and then flow back to the second interface 102.

[0229] Specifically, the first preset temperature can be selected from conventional temperatures in existing technologies, such as 35°C, at which most people would find the passenger cabin stuffy.

[0230] It should be noted that the first air conditioning unit 105 in this embodiment can be an air conditioner for the driver's seat, an air conditioner for the passenger seat, or an air conditioner for a specific area in the rear.

[0231] Furthermore, in order to ensure stable cooling of the evaporator 402, the heat generated by the condenser 403 needs to be discharged to the outside. At this time, the second outlet of the third three-way valve 203 is opened and the first outlet is closed, so that the liquid heat exchange medium in the second flow path 407 is introduced into the twelfth pipe 307. The liquid heat exchange medium flows to the second integrated valve 600 through the sixteenth pipe 702. The second integrated valve 600 is controlled to connect the motor thermal management circuit and the radiator 503 circuit in series. The shut-off valve 208 is opened to connect the thirteenth pipe 308 and the sixteenth pipe 702.

[0232] Through the above steps, the heat generated by the condenser 403 is fully released to the outside atmosphere through the radiator 503, thereby ensuring that the evaporator 402 fully cools the liquid heat exchange medium.

[0233] This method ensures that the liquid heat exchange medium can at least enter the first air conditioning unit 1051 or the second air conditioning unit 1052.

[0234] Example 5

[0235] In this embodiment, the thermal management system of Embodiment 3 is used to provide a thermal management system control method for a vehicle.

[0236] like Figure 3 and Figure 4 As shown, this embodiment provides a cooling mode for the first and second passenger compartments: this mode is used to cool the passenger compartments during summer or other external heating conditions, when the battery operates at low power and does not require heat dissipation. It includes the following steps:

[0237] This embodiment can directly control the start-up of the first air conditioning unit 1051 and the second air conditioning unit 1052 by automatically acquiring the external temperature. When using automatic control, the following signal acquisition method can be adopted:

[0238] Obtain the temperatures of the first and second passenger cabins;

[0239] When the temperature of the first passenger compartment and the second passenger compartment is higher than the second preset heating temperature, the second three-way valve 202 is opened, controlling the liquid heat exchange medium in the first pipe 103 to enter the first air conditioning unit 1051 through the first pipe 103, and then return to the second interface 102 through the second pipe 104; the liquid heat exchange medium in the second pipe 106 is controlled to enter the second air conditioning unit 1052 through the second pipe 106, and then return to the second interface 102. Specifically, the second preset heating temperature can be selected from conventional temperatures in the prior art, such as 35°C, at which point most people would find the passenger compartment stuffy. The control steps in this embodiment are similar to those in Embodiment 4, the main difference being that the cooling of both passenger areas can be displayed simultaneously.

[0240] It should be noted that the first passenger compartment and the second passenger compartment can be the driver's seat and the front passenger seat, or the driver's seat and the rear area, as long as they are two different areas.

[0241] As another way to cool down the first and second passenger cabins, this embodiment can also adopt the method of direct passenger control activation. In this case, the temperature of the passenger cabin may not be high, but the passenger activates the cooling of the passenger cabin due to their own needs.

[0242] In this embodiment, the liquid heat exchange medium that has completed heat exchange in the second air conditioning unit 1052 will return to the second interface 102 through the fourth pipe 107. Alternatively, the second pipe 104 and the fourth pipe 107 can be combined to form a fifth pipe 108, and then both pipes can be transported to the second interface 102.

[0243] Example 6

[0244] In this embodiment, the thermal management system of Embodiment 3 is used to provide a thermal management system control method for a vehicle.

[0245] This embodiment is based on Embodiment 5 and aims to provide different levels of cooling modes for the first and second passenger cabins: This mode is used to cool the passenger cabins in summer or other external heating conditions, when the battery operates at low power and does not require heat dissipation.

[0246] Specifically, the opening ratio of the first outlet and the second outlet of the second three-way valve 202 is adjusted to control the flow rate of the liquid heat exchange medium entering the first air conditioning unit 1051 and the second air conditioning unit 1052.

[0247] When the flow rates of the first and second outlets of the second three-way valve 202 are both 50%, the first air conditioning unit 1051 and the second air conditioning unit 1052 can achieve the same cooling effect.

[0248] In this embodiment, the cooling of the two areas can be adjusted according to the different needs of the driver and front passenger. The flow rates of the first and second outlets of the second three-way valve 202 are distributed proportionally. For example, if the flow rate of the first outlet accounts for 10%, then the flow rate of the second outlet accounts for 90%, and the cooling effect of the second air conditioning unit 1052 corresponding to the second outlet will be better.

[0249] Example 7

[0250] In this embodiment, the thermal management system of Embodiment 3 is used to provide a thermal management system control method for a vehicle.

[0251] like Figure 5 and Figure 6 As shown, this embodiment provides a mode for separately cooling the battery thermal management circuit. This mode is used when the passenger cabin is unoccupied and the battery is being cooled. This can be during normal charging in warm or cool weather, or during supercharging. Regardless of the situation, this control method can be used whenever the battery temperature is too high and cooling is required. It includes the following steps:

[0252] Obtain the battery temperature;

[0253] Specifically, multiple temperature sensors are installed on the battery pack 501, and the temperature detected by the temperature sensors is sent to the vehicle controller in real time.

[0254] Specifically, the battery temperature during car charging is approximately 25-45℃. When the temperature exceeds 45℃, the battery temperature can be considered too high.

[0255] When the battery temperature is higher than the battery preset heating temperature, the second outlet of the first three-way valve 201 is opened and the first outlet is closed, so that the liquid heat exchange medium in the first pipeline 103 is connected to the battery thermal management circuit through the fifteenth pipeline 701.

[0256] The first inlet of the fifth three-way valve 205 is closed, the second inlet of the fifth three-way valve 205 is opened, and the outlet of the fifth three-way valve 205 is opened, connecting the seventh pipeline 110 and the second pipeline 104. The liquid heat exchange medium flowing out through the sixth pipeline 109 is connected to the fifteenth pipeline 701. The second integrated valve 600 is controlled to connect the liquid heat exchange medium in the sixth pipeline 109 to the battery thermal management circuit through the fifteenth pipeline 701. Then, the liquid heat exchange medium that has completed the cooling operation flows back to the integrated valve 100 through the fourth interface 302.

[0257] With the above configuration, the cooling liquid heat exchange medium in the first flow path 406 is directly supplied to the fourth thermal management subsystem, and the heat exchange between the fourth thermal management subsystem and the battery pack 501 is completed, thereby achieving individual cooling of the battery pack 501.

[0258] Example 8

[0259] In this embodiment, the thermal management system of Embodiment 3 is used to provide a thermal management system control method for a vehicle.

[0260] like Figure 7 and Figure 8 As shown, this embodiment provides a mode for simultaneous cooling of the battery thermal management circuit and the passenger compartment. This mode is used when the battery pack 501 is supercharged while passengers are in the passenger compartment, or when the temperature of the passenger compartment and battery pack 501 rises due to operation in warm weather. In either case, this control method can be used whenever both the battery temperature and the passenger compartment temperature are too high. It includes the following steps:

[0261] Acquire the temperature of the battery and passenger cabin;

[0262] When the battery temperature is higher than the preset battery heating temperature;

[0263] Furthermore, if the temperature of the first passenger compartment is higher than the first preset heating temperature and / or the temperature of the second passenger compartment is higher than the second preset heating temperature, such as when the battery temperature is higher than 45°C or the passenger compartment temperature is higher than 30°C.

[0264] The first and second outlets of the first three-way valve 201 are opened, and the first and / or second outlets of the second three-way valve 202 are opened, so that the liquid heat exchange medium in the first pipeline 103 enters the first pipeline 103 and the sixth pipeline 109 respectively.

[0265] At this time, several different modes can be used: cooling the first air conditioning unit 1051 and the battery thermal management circuit; cooling the second air conditioning unit 1052 and the battery thermal management circuit; cooling the first air conditioning unit 1051, the second air conditioning unit 1052 and the battery thermal management circuit.

[0266] Control the second integrated valve 600 to connect the liquid heat exchange medium in the sixth pipeline 109 to the fourth thermal management subsystem in the battery thermal management circuit through the fifteenth pipeline 701;

[0267] The inlet of the sixth three-way valve 206 is opened, the first outlet is opened, and the second outlet is closed, so that the second pipeline 104 (the fifth pipeline 108) is open;

[0268] The first and second inlets of the fifth three-way valve 205 are opened, and the outlet of the fifth three-way valve 205 is opened, so that the liquid heat exchange medium in the fifteenth pipeline 701 flows back to the second interface 102 through the fifth three-way valve 205.

[0269] Example 9

[0270] In this embodiment, the thermal management system of Embodiment 3 is used to provide a thermal management system control method for a vehicle.

[0271] This embodiment is based on Embodiment 8 and aims to provide different levels of cooling modes for the passenger compartment and the battery: the mode provided in this embodiment is the simultaneous cooling of the battery and the passenger compartment.

[0272] In this embodiment, the cooling of the two areas can be adjusted according to the different temperatures of the passenger compartment and the battery pack 501. The flow rates of the first outlet and the second outlet of the first three-way valve 201 are distributed proportionally. For example, if the flow rate of the first outlet accounts for 10%, then the flow rate of the second outlet accounts for 90%, and the cooling effect of the battery corresponding to the second outlet will be better.

[0273] Example 10

[0274] In this embodiment, the thermal management system of Embodiment 3 is used to provide a thermal management system control method for a vehicle.

[0275] like Figure 9 and Figure 10 As shown, this embodiment provides a mode for separately heating the passenger compartment: This mode is used when passengers in the passenger compartment need hot air but there is no need to heat the battery pack 501, such as providing hot air to passengers separately when the vehicle is parked. It includes the following steps:

[0276] When the temperature of the first passenger cabin is lower than the first preset cooling temperature, the first three-way valve 201 and / or the second three-way valve 202 are first controlled to close. At this time, the liquid heat exchange medium in the first flow path 406 will not be able to enter the integrated valve 100.

[0277] The control valve 203 is opened, and the liquid heat exchange medium in the second flow path 407 enters the first air conditioning unit 1051 through the eighth pipe 303, and then flows back to the third interface 301 through the ninth pipe 304. Specifically, the first preset cooling temperature can be 10°C.

[0278] It should be noted that the first passenger compartment here can be either the driver's seat or the front passenger seat.

[0279] Example 11

[0280] This embodiment is based on Embodiment 10, providing a thermal management system control method. The main difference compared to Embodiment 10 is that this embodiment can simultaneously heat both the first and second passenger cabins. Figure 11 and Figure 12 As shown, it includes the following steps:

[0281] Obtain the temperatures of the first and second passenger cabins;

[0282] When the temperature of the first passenger cabin and the second passenger cabin is lower than the second preset cooling temperature, the first outlet of the third three-way valve 203 is opened, the second outlet of the third three-way valve 203 is closed, the first outlet and the second outlet of the fourth three-way valve 204 are opened, the liquid heat exchange medium in the second flow path 407 is controlled to enter the first air conditioning unit 1051 through the eighth pipe 303, and return to the fourth interface 302 through the ninth pipe 304; the liquid heat exchange medium in the second pipe 106 is controlled to enter the second air conditioning unit 1052 through the tenth pipe 305, and return to the fourth interface 302.

[0283] As a variant, the first air conditioning unit 1051 and the second air conditioning unit 1052 can also be started manually. In this case, the temperature inside the vehicle is not high enough to make people feel cold, but passengers in the passenger compartment can manually start the air conditioning due to specific needs.

[0284] Example 12

[0285] This embodiment provides a mode for simultaneous heating of the battery and the passenger compartment. This mode is used when the passenger compartment is occupied during cooling and heating of both the battery pack 501 and the passengers is required. Heating the battery pack 501 through the fourth thermal management subsystem can improve the battery pack 501's own range. Figure 13 and Figure 14 As shown, it includes the following steps:

[0286] The temperature of the space where the air conditioning unit 105 is located is obtained. In this embodiment, the space where the air conditioning unit 105 is located can be the temperature of the first passenger cabin and / or the second passenger cabin.

[0287] Obtain the battery temperature;

[0288] When the battery temperature is lower than the preset cooling temperature; and

[0289] When the temperature of the first passenger cabin and / or the second passenger cabin is lower than the second preset cooling temperature, the first three-way valve 201 and / or the second three-way valve 202 are closed. At this time, the liquid heat exchange medium in the first flow path 406 will not enter the integrated valve 100.

[0290] The system controls the opening of the first and second outlets of the third three-way valve 203, the opening of the first and second outlets of the fourth three-way valve 204, and controls the liquid heat exchange medium in the second flow path 407 to enter the first air conditioning unit 1051 through the eighth pipe 303 and return to the fourth interface 302 through the ninth pipe 304; and / or controls the liquid heat exchange medium in the second pipe 106 to enter the second air conditioning unit 1052 through the tenth pipe 305 and return to the fourth interface 302.

[0291] The liquid heat exchange medium is controlled to enter the fourth thermal management subsystem of the battery thermal management circuit.

[0292] Specifically, the liquid heat exchange medium enters the thirteenth pipe 308 through the second outlet of the third three-way valve 203, and then flows to the sixteenth pipe 702, and then enters the interior of the second integrated valve 600 to control the second integrated valve 600. The sixteenth pipe 702 is connected in series with the battery thermal management circuit.

[0293] Example 13

[0294] This embodiment is based on Embodiment 12, and the main difference from Embodiment 12 is that it can provide different heating effects for the passenger compartment and the battery, including the following steps:

[0295] The opening ratio of the first and second outlets of the third three-way valve 203 is controlled to control the flow rate of the liquid heat exchange medium entering the fourth thermal management subsystem of the battery thermal management circuit and the air conditioning unit 105.

[0296] If the flow rate of the first outlet is controlled at 40% and the flow rate of the second outlet is controlled at 60%, the battery thermal management circuit can obtain more heat.

[0297] Example 14

[0298] In this embodiment, the thermal management system of Embodiment 3 is used to provide a thermal management system control method for a vehicle.

[0299] The heating mode provided in this embodiment is based on embodiments 12 and 13: when the ambient temperature of the vehicle or the temperature of the liquid heat exchange medium in the first flow path 406 is too low, this mode is used for heating. In this embodiment, an auxiliary heating module 411 is provided on the second flow path 407, such as... Figure 16 and Figure 17 As shown, it includes the following steps:

[0300] Get the ambient temperature outside the car;

[0301] When the outdoor ambient temperature is below -10℃, the auxiliary heating module 411 is activated.

[0302] The system controls the opening of the first and second outlets of the third three-way valve 203, the opening of the first and second outlets of the fourth three-way valve 204, and controls the liquid heat exchange medium in the second flow path 407 to enter the first air conditioning unit 1051 through the eighth pipe 303 and return to the fourth interface 302 through the ninth pipe 304; and / or controls the liquid heat exchange medium in the second pipe 106 to enter the second air conditioning unit 1052 through the tenth pipe 305 and return to the fourth interface 302.

[0303] Control the second integrated valve 600 to connect the twelfth pipeline 307, the battery thermal management circuit and the thirteenth pipeline 308;

[0304] The second outlet of the third three-way valve 203 is opened, allowing the liquid heat exchange medium to flow into the fifth thermal management subsystem of the motor thermal management circuit through the twelfth pipe 307. Heat exchange is completed between the fifth thermal management subsystem and the motor. The shut-off valve 208 is then opened, allowing the liquid heat exchange medium that has returned through the battery thermal management circuit to return to the fourth interface 302 through the thirteenth pipe 308.

[0305] Example 15

[0306] In this embodiment, the thermal management system of Embodiment 3 is used to provide a thermal management system control method for a vehicle.

[0307] The heating mode provided in this embodiment is based on Embodiments 12 and 13: When the ambient temperature of the vehicle is below 0°C, in order to provide heating to the passenger compartment and the battery thermal management circuit, a gas-liquid separator 412 is installed on the first heat exchange medium circulation pipeline between the compressor 401 and the expansion valve 404. One end of the hot gas bypass pipeline is located between the compressor 401 and the expansion valve 404, and the other end acts on the gas-liquid separator 412. A bypass expansion valve 410 is installed on the hot gas bypass pipeline, such as... Figure 17 and Figure 18 As shown, it includes the following steps:

[0308] Get the ambient temperature outside the car;

[0309] When the outdoor ambient temperature is between -20℃ and 0℃, the bypass expansion valve 410 on the hot gas bypass pipeline is opened.

[0310] The system controls the first outlet of the third three-way valve 203, the first outlet and the second outlet of the fourth three-way valve 204 to open, controls the liquid heat exchange medium in the second flow path 407 to enter the first air conditioning unit 1051 through the eighth pipe 303, and returns to the fourth interface 302 through the ninth pipe 304; and / or controls the liquid heat exchange medium in the second pipe 106 to enter the second air conditioning unit 1052 through the tenth pipe 305, and returns to the fourth interface 302.

[0311] Control the second integrated valve 600 to connect the twelfth pipeline 307, the battery thermal management circuit and the thirteenth pipeline 308;

[0312] The second outlet of the third three-way valve 203 is opened to allow the liquid heat exchange medium to flow into the motor thermal management circuit through the twelfth pipe 307. The shut-off valve 208 is opened to allow the liquid heat exchange medium that flows back through the battery thermal management circuit to flow back to the fourth interface 302 through the thirteenth pipe 308.

[0313] Specifically, the hot gas bypass can be used in heating environments where the ambient temperature is below 0°C and above -20°C. In this case, the bypass expansion valve 410 works as the make-up gas expansion valve 404 to ensure low pressure. For example, when the refrigerant is R134A and the high pressure is 16 BarA, the heat exchanger water circuit can provide 60°C air supply to the passenger compartment and battery pack 501, and control the refrigerant pressure to a low pressure of 4 BarA.

[0314] Example 16

[0315] In this embodiment, the thermal management system of Embodiment 3 is used to provide a thermal management system control method for a vehicle.

[0316] The mode provided in this embodiment is as follows: while heating the passenger cabin, the fifth thermal management subsystem collects the heat from the motor itself, and then heats the battery, thereby effectively utilizing the motor's own heat, such as... Figure 19 and Figure 20 As shown, the control steps are as follows:

[0317] Get the ambient temperature outside the car;

[0318] When the outdoor ambient temperature is between 0℃ and 18℃, the first outlet of the third three-way valve 203 is opened, the first and second outlets of the fourth three-way valve 204 are opened, the liquid heat exchange medium in the second flow path 407 is controlled to enter the first air conditioning unit 1051 through the eighth pipe 303, and return to the fourth interface 302 through the ninth pipe 304; and / or the liquid heat exchange medium in the tenth pipe 305 is controlled to enter the second air conditioning unit 1052 through the tenth pipe 305, and return to the fourth interface 302;

[0319] It should be noted that the eighth pipe 303 and the tenth pipe 305 can be combined into one pipe.

[0320] The second integrated valve 600 is controlled to connect the battery thermal management circuit and the motor thermal management circuit in series. This series connection allows heat to be transferred from the motor thermal management circuit to the battery thermal management circuit. Specifically, the fifth thermal management subsystem in the motor thermal management circuit absorbs the heat generated by the motor, then transfers it to the liquid heat exchange medium, and further into the fourth thermal management subsystem. The fourth thermal management subsystem then completes the heat exchange with the battery, thereby transferring the heat from the motor to the battery.

[0321] Furthermore, the control method provided in this embodiment also includes:

[0322] Connect the radiator 503 circuit to the seventh pipe 110 and the sixth pipe 109;

[0323] The first outlet of the first three-way valve 201 is opened and the second outlet is closed, so that the liquid heat exchange medium in the first flow path 406 enters the sixth pipeline 109;

[0324] Control the sixth three-way valve 206 to connect the seventh pipeline 110 to the second interface 102.

[0325] In applications where heating is required in ambient temperatures between 0°C and 18°C, the EXV1 evaporator pressure is lowered to 2 BarA, gradually reducing the water temperature in the water circuit to -10°C. The radiator 503 then absorbs heat from the environment through a temperature difference of 10-38°C. Any insufficient heat can be supplemented by the HVH (Heat-Ventilator).

[0326] Example 17

[0327] In this embodiment, the thermal management system of Embodiment 3 is used to provide a thermal management system control method for a vehicle.

[0328] The mode provided in this embodiment is: adjusting the temperatures of the first air conditioning unit 1051 and the second air conditioning unit 1052 so that there is a certain difference between the temperatures of the first air conditioning unit 1051 and the second air conditioning unit 1052. For example, the temperature of the driver's seat is adjusted to 26℃, and the temperature of the passenger seat is adjusted to 20℃. This includes the following steps:

[0329] The first outlet of the first three-way valve 201 is opened, and the second outlet is closed;

[0330] With the above-described configuration, the liquid heat exchange medium flows only toward the air conditioning unit 105 and does not flow out into the battery return path.

[0331] The first and second outlets of the second three-way valve 202 are opened, so that the liquid heat exchange medium enters the first air conditioning unit 1051 and the second air conditioning unit 1052 through the first pipeline 103 and the third pipeline 106 respectively, and flows back to the second interface 102 through the second pipeline 104.

[0332] The above steps complete the operation of introducing liquid heat exchange medium into the first air conditioning unit 1051 and the second air conditioning unit 1052.

[0333] The first outlet of the third three-way valve 203 is opened, the second outlet of the third three-way valve 203 is closed, and at least one of the first and second outlets of the fourth three-way valve 204 is opened, so that the liquid heat exchange medium enters at least one of the eighth pipe 303 or the tenth pipe 305.

[0334] Through the above steps, the liquid heat exchange medium is introduced into at least one of the first air conditioning unit 1051 and the second air conditioning unit 1052, thereby completing the doping of liquid heat exchange medium at different temperatures in the first air conditioning unit 1051 and the second air conditioning unit 1052, thus realizing the difference in core structure temperature in the first air conditioning unit 1051 and the second air conditioning unit 1052.

[0335] Furthermore, when the first and second outlets of the fourth three-way valve 204 are simultaneously open, the opening degree of the first and second outlets of the fourth three-way valve 204 is controlled to adjust the flow rate of the liquid heat exchange medium entering the eighth pipe 303 and the tenth pipe 305. This allows for further adjustment of the temperatures of the first air conditioning unit 1051 and the second air conditioning unit 1052. For example, when the temperature of the first air conditioning unit 1051 needs to be higher than the temperature of the second air conditioning unit 1052, the opening degree of the first outlet of the fourth three-way valve 204 is controlled to be greater than the opening degree of the second outlet, thereby allowing more liquid heat exchange medium to enter the first air conditioning unit 1051.

[0336] Furthermore, by controlling the opening of the second outlet of the third three-way valve 203, the opening of the shut-off valve 208, and the opening degree of the first and second outlets of the third three-way valve 203, the flow rate of the liquid heat exchange medium entering the twelfth pipe 307 and the eighth pipe 303 is adjusted. By controlling the opening of the second outlet of the third three-way valve 203 and the shut-off valve 208, a portion of the liquid heat exchange medium will enter the twelfth pipe 307 and flow out to the outside of the integrated valve 100. In the same way, the flow rate of the liquid heat exchange medium entering the eighth pipe 303 can also be adjusted, thereby achieving temperature regulation.

[0337] Furthermore, the control method also includes: controlling the sixth three-way valve 206 to connect with the fourteenth pipe 309, adjusting the opening of the second outlet of the sixth three-way valve 206, and adjusting the flow rate into the thirteenth pipe 308. Through the above-described configuration, a portion of the liquid heat exchange medium flowing out of the air conditioning unit 105 does not need to return to the first flow path 406 for cooling, but instead flows to the second flow path 407 for heating, thereby ensuring that the water temperature of the liquid heat exchange medium flowing into the first air conditioning unit 1051 and the second air conditioning unit 1052 is normal.
