[0074] Reference below Figure 1-Figure 18 A thermal management system 100 and a vehicle according to an embodiment of the present invention are described.

[0075] In a first aspect, the present application proposes a thermal management system 100, such as Figure 1 As shown, the thermal management system 100 includes: an air conditioning module, a refrigerator component and an integrated module.

[0076] Among them, the integrated module 10 is connected to the air-conditioning module and the refrigerator assembly 70. The integrated module 10 includes multiple flow paths and multiple valves for controlling the conduction and closing of the multiple flow paths. The multiple valves are selectively opened and closed to control the air-conditioning module and the refrigerator assembly 70 to selectively connect the refrigerant.

[0077] Specifically, combined Figure 1 and Figure 2 As shown, the integrated module 10 has a first interface 101 to a ninth interface 109, the air conditioning module is connected to the first interface 101 to the fifth interface 105, and the refrigerator assembly 70 has a ninth port 71 and a tenth port 72, the ninth port 71 is connected to the eighth interface 108, and the tenth port 72 is connected to the ninth interface 109, so that the integrated module 10 is suitable for controlling the air conditioning module and the refrigerator assembly 70 to selectively connect the refrigerant.

[0078] The integrated module 10 can be connected to the air-conditioning module through the first interface 101, the second interface 102, the third interface 103, the fourth interface 104 and the fifth interface 105, so that the high-temperature refrigerant and the low-temperature refrigerant in the air-conditioning module can flow through the integrated module 10 to realize the corresponding thermal management functions, such as: internal circulation heat exchange, external circulation heat exchange, etc.

[0079] Furthermore, the ninth port 71 and the tenth port 72 of the refrigerator assembly 70 are connected to the integrated module 10, so that the high-temperature refrigerant or the low-temperature refrigerant in the air-conditioning module can enter the refrigerator assembly 70 or flow out of the refrigerator assembly 70 through the eighth interface 108 and the ninth interface 109 of the integrated module 10, thereby realizing the temperature regulation function of the refrigerator assembly 70, such as refrigerator cooling and refrigerator heating, through the heat exchange of the high-temperature refrigerant or the low-temperature refrigerant in the refrigerator assembly 70.

[0080] That is to say, the ninth port 71 and the tenth port 72 of the refrigerator assembly 70 are connected to the eighth interface 108 and the ninth interface 109 respectively, so that the refrigerant in the integrated module 10 can flow into the interior of the refrigerator assembly 70, realize the heat exchange of the refrigerator assembly 70, and then flow back to the integrated module 10, and then flow back to the air-conditioning module to complete the refrigerant heat exchange cycle of the refrigerator assembly 70.

[0081] It can be understood that the thermal management system 100 of the embodiment of the present application connects the integrated module 10 with the refrigerator assembly 70, so that the refrigerator assembly 70 and the air-conditioning module can share an integrated module 10, which can improve the degree of integration. There is no need to separately configure the refrigerant supply pipeline of the refrigerator assembly 70 based on the use requirements of the refrigerator assembly 70, so that the air-conditioning module and the refrigerator assembly 70 can respectively realize their respective heat exchange functions, which can not only enrich the functions of the thermal management system 100, but also simplify the piping structure of the thermal management system 100, simplify the wiring harness distribution, and reduce the difficulty of platformization.

[0082] According to the thermal management system 100 of the embodiment of the present application, the thermal management system 100 has a higher degree of integration, can implement platform design, reduce the difficulty of layout, reduce the difficulty of subsequent repair and maintenance, and can enrich the functions of the thermal management system 100 to meet the diverse usage needs of users and improve the user experience.

[0083] like Figure 1 and Figure 3 As shown, according to some embodiments of the present application, the thermal management system 100 further includes: a battery cold plate assembly 60 , and the integrated module 10 is further adapted to control the air conditioning module to selectively communicate with the battery cold plate assembly 60 via a refrigerant.

[0084] Therefore, the integrated module 10 can control the flow of refrigerant in the battery cold plate assembly 60 to achieve direct cooling or direct heating of the battery through the flow of high-temperature refrigerant or low-temperature refrigerant, which can not only effectively improve the temperature regulation efficiency and temperature regulation effect of the battery, but also the battery temperature regulation can be synchronized with the temperature regulation of the refrigerator assembly 70 and the temperature regulation of the cockpit by the air-conditioning module, which can enrich the temperature regulation mode and improve the user experience.

[0085] According to some embodiments of the present application, the air-conditioning module includes a compressor 20, an outdoor condenser 30 and an evaporator 50, the compressor 20 has a compressor inlet 21 and a compressor outlet 22, the compressor outlet 22 is connected to one end of the outdoor condenser 30, and the other end of the outdoor condenser 30 is connected to the integrated module 10; the integrated module 10 is suitable for controlling one end of the evaporator 50 and one end of the refrigerator assembly 70 to be connected to the refrigerant of the integrated module 10, and controlling the other end of the evaporator 50 to be connected to the compressor inlet 21, and controlling the other end of the refrigerator assembly 70 to be connected to the compressor inlet 21, or controlling the other end of the refrigerator assembly 70 to be connected to the compressor inlet 21 through the integrated module 10.

[0086] Among them, the outdoor condenser 30 has a first port 31 and a second port 32, the first port 31 is located at one end of the outdoor condenser 30, and the second port 32 is located at the other end of the outdoor condenser 30, and the integrated module 10 is suitable for controlling the evaporator 50 and the refrigerator assembly 70 to be connected to the integrated module 10, and controlling the evaporator 50 to be connected to the compressor inlet 21, or controlling the evaporator 50 to be connected to the compressor inlet 21 through the integrated module 10, and at the same time, it can also control the other end of the refrigerator assembly 70 to be connected to the compressor inlet 21, or further connected to the compressor inlet 21 through the integrated module 10.

[0087] Specifically, the air-conditioning module includes: a compressor 20, an outdoor condenser 30, an indoor condenser 40, and an evaporator 50, and the compressor 20 has a compressor inlet 21 and a compressor outlet 22, the compressor outlet 22 is connected to the first interface 101, and the compressor inlet 21 is connected to the second interface 102, the first port 31 of the outdoor condenser 30 is connected to the compressor outlet 22, the second port 32 is connected to the third interface 103, the third port 41 of the indoor condenser 40 is connected to the compressor outlet 22, the fourth port 42 is connected to the fourth interface 104, the fifth port 51 of the evaporator 50 is connected to the fifth interface 105, and the sixth port 52 is connected to the compressor inlet 21.

[0088] The compressor 20 can then be selectively connected to the external condenser 30 , the internal condenser 40 , the evaporator 50 , the battery cold plate assembly 60 and the refrigerator assembly 70 through the integrated module 10 to achieve corresponding functions.

[0089] Specifically, the first interface 101 is connected to the compressor outlet 22, and the second interface 102 is connected to the compressor inlet 21, so that the refrigerant can flow out from the compressor outlet 22 and flow back to the compressor 20 from the compressor inlet 21, and the first port 31 of the external condenser 30 is connected to the compressor outlet 22, and the second port 32 is connected to the third interface 103, so that the refrigerant flowing out of the compressor 20 can enter the integrated module 10 after passing through the external condenser 30 for heat exchange, the third port 41 of the in-vehicle condenser 40 is connected to the compressor outlet 22, and the fourth port 42 is connected to the fourth interface 104, so that the refrigerant flowing out of the compressor 20 can enter the integrated module 10 after passing through the in-vehicle condenser 40 for heat exchange, the fifth port 51 of the evaporator 50 is connected to the fifth interface 105, and the sixth port 52 is connected to the compressor inlet 21, so that the refrigerant flowing through the integrated module 10 can flow through the evaporator 50 and flow back to the compressor 20 after completing the heat exchange.

[0090] In summary, through the setting of the integrated module 10, the flow paths and valve systems for heat exchange of the compressor 20, the in-vehicle condenser 40, the out-of-vehicle condenser 30, the evaporator 50, the refrigerator assembly 70 and the battery cold plate assembly 60 of the air-conditioning module can be integrated on the integrated module 10, and the integrated setting of various valve bodies and valve systems can be realized, which can simplify the piping structure of the thermal management system 100, simplify the wiring harness distribution, reduce the difficulty of installation, reduce the difficulty of platformization, and facilitate subsequent repair and maintenance.

[0091] It should be pointed out that through the integrated module 10 and the multiple flow paths and multiple valves integrated thereon, the temperature regulation of the battery, the temperature regulation of the cockpit and the temperature regulation of the refrigerator assembly 70 can be achieved. While the air-conditioning module is performing air-conditioning refrigeration, if the refrigerator assembly 70 is performing refrigerator refrigeration, the refrigerant will flow through the flow path where the evaporator 50 is located and the flow path where the refrigerator assembly 70 is located (refrigerator heat exchange circuit 122) at the same time, which will cause uneven pressure distribution between the circuit where the evaporator 50 is located and the refrigerator heat exchange circuit 122, and even cause the pressure of one of the circuits to be too high and the pressure of one circuit to be too low, which will not only pose a safety hazard but also reduce the temperature regulation effect of one of the circuits.

[0092] Based on this, the present application sets a pressure balancing mechanism between the evaporator 50 and the compressor inlet 21 , or sets a pressure balancing mechanism between the refrigerator assembly 70 and the compressor inlet 21 .

[0093] In this way, when air conditioning and refrigerator cooling are performed at the same time, a pressure balance can be maintained between the flow path of the evaporator 50 and the refrigerator heat exchange circuit 122, so that the refrigerant flow in the two refrigerant circuits can be kept stable, so that the evaporator 50 and the refrigerator assembly 70 can maintain a good temperature regulation effect, and excessive pressure in one circuit can be avoided, and the working stability, safety and reliability of the thermal management system 100 can also be improved.

[0094] It should be pointed out that the pressure balancing structure is used to balance the pressure between the two circuits. It can make the pressure in the two circuits completely consistent, or it can regulate the pressure between the two based on a set pointer to avoid excessive pressure in either circuit. At the same time, it can also maintain the pressure difference between the two within a controllable range. This application will not go into details.

[0095] Exemplarily, the pressure balancing mechanism can be constructed as a second electronic expansion valve 1291, and the second electronic expansion valve 1291 is arranged between the evaporator 50 and the compressor inlet 21; or the pressure balancing mechanism can be constructed as a supercharger, and a supercharger is arranged between the refrigerator assembly 70 and the compressor inlet 21.

[0096] It should be noted that a temperature sensor 1292 may be provided between the sixth port 52 of the evaporator 50 and the second electronic expansion valve 1291, and the temperature of the cooling medium flowing through the evaporator 50 may be obtained in real time through the temperature sensor 1292. Fig. 9 As shown, according to some embodiments of the present application, the air-conditioning module includes a compressor 20, the integrated module 10 includes a heat exchanger 11, the compressor outlet 22 is connected to the refrigerator assembly 70 by refrigerant, or the compressor outlet 22 is connected to the refrigerator assembly 70 by refrigerant through the integrated module 10, the refrigerator assembly 70 is connected to one end of the heat exchanger 11 through at least one flow path of the integrated module 10, and the other end of the heat exchanger 11 is connected to the compressor inlet 21 through at least one flow path of the integrated module 10.

[0097] Specifically, the heat exchanger 11 has a refrigerant side inlet and an inlet and an outlet on the cooling medium side. The refrigerant side inlet and outlet can be connected to the refrigerant of the refrigerator assembly 70 so that the refrigerant after heating the refrigerator can flow through the heat exchanger 11 and further flow back to the compressor 20.

[0098] In this way, by setting up the heat exchanger 11 and connecting the heat exchanger 11 with the refrigerant of the refrigerator assembly 70, the refrigerant flowing through the refrigerator assembly 70 can exchange heat with the cooling medium in the heat exchanger 11 and then flow back to the compressor 20, thereby realizing the heating function of the refrigerator.

[0099] like Figure 1As shown, the air-conditioning module also includes an evaporator 50, and a third throttle valve 1271 and the evaporator 50 are also provided between the other end of the heat exchanger 11 and the compressor inlet 21, the other end of the heat exchanger 11 is connected to one end of the third throttle valve 1271 through at least one flow path, the other end of the third throttle valve 1271 is connected to one end of the evaporator 50, and the other end of the evaporator 50 is connected to the compressor inlet 21.

[0100] It should be pointed out that the third throttle valve 1271 is a throttling expansion valve. When adjusting the temperature of the passenger compartment, the low-temperature and low-pressure mixed refrigerant can enter the evaporator 50 and absorb the ambient temperature to achieve cooling of the passenger compartment, and the cooling of the passenger compartment and heating of the refrigerator can be carried out simultaneously, thereby realizing air conditioning cooling + refrigerator heating mode.

[0101] It should be pointed out that in order to improve the integration level of the integrated module 10 and simplify the layout of pipelines and wiring harnesses in the thermal management system 100, the third throttle valve 1271 can be integrated into the integrated module 10, and the other end of the third throttle valve 1271 is connected to one end of the evaporator 50 through at least one flow path (such as the seventh branch 127).

[0102] In some embodiments, the air-conditioning module also includes a compressor 20 and an outdoor condenser 30, the compressor 20 having a compressor inlet 21 and a compressor outlet 22, the compressor outlet 21 is connected to one end of the outdoor condenser 30, and the other end of the outdoor condenser is connected to the integrated module 10; the integrated module 10 is suitable for controlling one end of the battery cold plate assembly 60 and one end of the refrigerator assembly 70 to be connected to the refrigerant of the integrated module 10, and controlling the other end of the battery cold plate assembly 60 to be connected to the compressor inlet 21, or controlling the other end of the battery cold plate assembly 60 to be connected to the compressor inlet 21 through the integrated module 10, and controlling the other end of the refrigerator assembly 70 to be connected to the compressor inlet 21, or controlling the other end of the refrigerator assembly 70 to be connected to the compressor inlet 21 through the integrated module 10.

[0103] It should be pointed out that the temperature regulation of the battery, the cockpit and the refrigerator assembly 70 can be achieved through the integrated module 10 and the multiple flow paths and multiple valves integrated thereon. While the battery cold plate assembly 60 performs battery cooling, if the refrigerator assembly 70 performs refrigerator refrigeration, the refrigerant will flow through the flow path where the battery cold plate is located (battery heat exchange circuit 121) and the flow path where the refrigerator assembly 70 is located (refrigerator heat exchange circuit 122) at the same time, which will cause uneven pressure distribution between the battery heat exchange circuit 121 and the refrigerator heat exchange circuit 122, and even cause the pressure of one of the circuits to be too high and the pressure of one circuit to be too low, which will not only pose a safety hazard, but also reduce the temperature regulation effect of one of the circuits.

[0104] Based on this, the present application provides a pressure balancing mechanism between the battery cold plate assembly 60 and the compressor inlet 21 , or provides a pressure balancing mechanism between the refrigerator assembly 70 and the compressor inlet 21 .

[0105] In this way, when the battery is cooled and the refrigerator is refrigerated at the same time, the pressure balance can be maintained between the battery heat exchange circuit 122 and the refrigerator heat exchange circuit 122, so that the refrigerant flow in the two refrigerant circuits can be kept stable, so that the battery cold plate assembly 60 and the refrigerator assembly 70 can maintain a good temperature regulation effect, and excessive pressure in one circuit can be avoided, and the working stability, safety and reliability of the thermal management system 100 can also be improved.

[0106] It should be pointed out that the pressure balancing structure is used to balance the pressure between the two circuits. It can make the pressure in the two circuits completely consistent, or it can regulate the pressure between the two based on a set pointer to avoid excessive pressure in either circuit. At the same time, it can also maintain the pressure difference between the two within a controllable range. This application will not go into details.

[0107] Exemplarily, the pressure balancing mechanism can be constructed as a first electronic expansion valve 1212, and the first electronic expansion valve 1212 is arranged between the battery cold plate assembly 60 and the compressor inlet 21; or the pressure balancing mechanism can be constructed as a supercharger, and the supercharger is arranged between the refrigerator assembly 70 and the compressor inlet 21.

[0108] That is to say, the thermal management system 100 of the embodiment of the present application can simultaneously realize air conditioning refrigeration and refrigerator refrigeration, and cold plate refrigeration and refrigerator refrigeration through the setting of the integrated module 10. In order to ensure the pressure balance between multiple refrigerant flow paths when the refrigeration is carried out simultaneously, a second electronic expansion valve 1292 can be set between the evaporator 50 and the compressor inlet 21, or a first electronic expansion valve 1212 can be set between the battery cold plate assembly 60 and the compressor inlet 21, or a supercharger can be set between the refrigerator assembly 70 and the compressor inlet 21.

[0109] like Figure 1 and Figure 2 As shown, the thermal management system 100 also includes: a battery cold plate assembly 60, the battery cold plate assembly 60 has N parallel cold plate loops 61, and each has a seventh port 611 and an eighth port 612, N is greater than or equal to 2, the seventh port is connected to the sixth interface 106, and the eighth port 612 is connected to the seventh interface 107.

[0110] Specifically, the battery cold plate assembly 60 is provided with N parallel cold plate loops 61, such as two, three or more, so as to improve the cooling efficiency of the cold plate through the N parallel cold plate loops 61, so that the cooling efficiency of the thermal management system 100 can meet the increasing battery cooling needs and achieve precise control of battery cooling. The seventh port 611 and the eighth port 612 of the N parallel cold plate loops 61 can be connected to the sixth interface 106 and the seventh interface 107 respectively, so that the high-temperature refrigerant or the low-temperature refrigerant in the air-conditioning module can flow into the parallel cold plate loops 61 through the integrated module 10 to exchange heat with the cold plate, and then flow back to the integrated module 10 after the heat exchange is completed, and then flow back to the air-conditioning module to complete the battery heat exchange cycle of the battery cold plate assembly 60.

[0111] Therefore, by setting up N parallel cold plate loops 61, the heat exchange efficiency of the cold plate can be improved, so that the cold plate can achieve temperature regulation of the battery more quickly, especially in high-power charging processes and in extremely cold environments, to achieve precise control of the battery temperature and improve the reliability and stability of the thermal management system 100. By integrating the refrigerant flow path of the refrigerator assembly 70 into the integrated module 10, the functions of the thermal management system 100 can be enriched to meet the diverse needs of users.

[0112] It should be noted that the N parallel cold plate loops 61 are connected to the same cold plate of the battery cold plate assembly 60 to reduce the difficulty of arranging the parallel cold plate loops 61 and improve the cooling efficiency and cooling effect of the battery.

[0113] like Fig.17 and Fig.18 As shown, according to some embodiments of the present application, the integrated module 10 includes: a module body 14 and a heat exchanger 11, the module body 14 defines a refrigerant side flow path 12 and a cooling medium side flow path 13, the heat exchanger 11 is arranged in the module body 14, and the refrigerant side inlet and outlet of the heat exchanger 11 are connected to the refrigerant side flow path 12, and the cooling medium side inlet and outlet of the heat exchanger 11 are connected to the cooling medium side flow path 13.

[0114] Among them, the heat exchanger 11 can realize heat exchange between the refrigerant side flow path 12 and the cooling medium side flow path 13, that is, the refrigerant and the cooling medium can dissipate heat through the heat exchanger 11, the cooling medium can be a liquid cooling medium such as coolant and water, and the refrigerant can be a phase change cooling medium such as R12, R22 (Freon), R134a, R407c, R410a, R290, R32, etc.

[0115] Specifically, a refrigerant flow channel and a cooling medium flow channel may be opened in the module body 14, and a valve system for controlling the on-off, opening and connectivity of the refrigerant flow channel and a valve system for controlling the on-off, opening and connectivity of the cooling medium flow channel may be installed thereon to realize the integrated setting of the thermal management system 100, and the refrigerant side flow path 12 and the cooling medium side flow path 13 are separated from each other, and the heat exchanger 11 has a cooling medium passage and a refrigerant passage, the cooling medium flows through the cooling medium passage, the refrigerant flows through the refrigerant passage, and heat exchange is realized in the heat exchanger 11, a coaxial tube structure and a capillary tube structure may be set in the heat exchanger 11 to realize heat exchange between the refrigerant and the cooling medium, thereby improving the heat exchange efficiency, and the heat exchanger 11 is integrated on the integrated module 10, which can further improve the degree of integration.

[0116] like Figure 2 As shown, in some embodiments, the refrigerant side flow path 12 includes: a battery heat exchange circuit 121, the battery heat exchange circuit 121 is formed on the integrated module 10 and is connected to the parallel cold plate circuit 61, the battery heat exchange circuit 121 includes: a plurality of first branches 1211 in parallel and a plurality of second branches 1213 in parallel, one end of the first branch 1211 is connected to the first interface 101 and the second interface 102, the other end of the first branch 1211 is connected to the seventh port 611, one end of the second branch 1213 is connected to the eighth port 612, and the other end of the second branch 1213 is connected to the second interface 102 and the third interface 103.

[0117] Specifically, the number of first branches 1211 is consistent with the number of second branches 1213, one end of the first branch 1211 can be selectively connected to the compressor inlet 21 through the first interface 101 and to the compressor outlet 22 through the second interface 102, the other end of the first branch 1211 is connected to the seventh port 611 of the parallel cold plate circuit 61 through the seventh port 611, one end of the second branch 1213 is connected to the eighth port 612 of the parallel cold plate circuit 61, and the other end of the second branch 1213 is connected to the second interface 102 or the third interface 103.

[0118] Therefore, if Figure 3 As shown, in the battery heating mode, the flow path of the refrigerant is compressor 20→first interface 101→first branch 1211→seventh port 611→parallel cold plate circuit 61→eighth port 612→second branch 1213→second interface 102→compressor 20. In the battery cooling mode, the flow path of the refrigerant is compressor 20→external condenser 30→third interface 103→second branch 1213→eighth port 612→parallel cold plate circuit 61→seventh port 611→second interface 102→compressor 20.

[0119] It should be pointed out that a first connecting branch can be provided between the plurality of first branches 1211, and a second connecting branch can be provided between the plurality of second branches 1213, and both the first connecting branch and the second connecting branch can be used for the convergence and diversion of the refrigerant, and the first connecting branch is connected to both the first interface 101 and the second interface 102, and the second connecting branch is connected to the third interface 103 and the second interface 102, so that when the refrigerant flows from the first branch 1211 to the second branch 1213, the first connecting branch receives the refrigerant flowing from the first interface 101 to the integrated module. The refrigerant in block 10 is divided into multiple first branches 1211, and the refrigerant in the second branch 1213 converges in the second connecting branch, flows to the second interface 102, and flows back to the compressor 20 through the second interface 102. In the process of the refrigerant flowing from the second branch 1213 to the first branch 1211, the refrigerant entering the third interface 103 is taken over by the second connecting branch, and then divided into multiple second branches 1213, flows to the first branch 1211, converges through the first connecting branch, and then flows back to the compressor 20 through the second interface 102.

[0120] In summary, the number of the first branch 1211 and the second branch 1213 can be multiple, not less than two, to improve the cooling efficiency of the cold plate, and the refrigerant can flow through the first branch 1211 and the second branch 1213 successively or flow through the second branch 1213 and the first branch 1211 successively to achieve battery cooling and battery heating respectively. Through the setting of the integrated module 10, the number of pipelines in the cold plate cooling part of the thermal management system 100 is reduced, and the compact and platform-based setting of the integrated module 10 is achieved.

[0121] like Figure 1 and Figure 2 As shown, a first electronic expansion valve 1212 is disposed in the first branch 1211 , and a first throttle valve 1214 is disposed in the second branch 1213 .

[0122] Specifically, a first electronic expansion valve 1212 is provided in each first branch 1211, and a first throttle valve 1214 is provided in each second branch 1213, so as to control the refrigerant flow rate of the first branch 1211 through the first electronic expansion valve 1212 to achieve control of the refrigerant evaporation temperature, and achieve flow control of the refrigerant flowing in the second branch 1213 through the first throttle valve 1214, thereby achieving precise control of the heat exchange temperature and heat exchange efficiency of the thermal management system 100 during battery cooling and battery heating.

[0123] In addition, by heating and cooling the battery, the battery life can be extended, the battery efficiency can be improved, the battery capacity and vehicle range can be increased at low temperatures, and the charging time can be effectively shortened.

[0124] It can be understood that by setting the first electronic expansion valve 1212, the first electronic expansion valve 1212 can be formed into a pressure balancing mechanism so that the battery heat exchange circuit 121 can maintain pressure balance with the refrigerator heat exchange circuit 122, thereby improving the reliability and safety of the thermal management system 100.

[0125] like Figure 2 As shown, the refrigerant side flow path 12 also includes: a refrigerator heat exchange circuit 122, the refrigerator heat exchange circuit 122 includes: a third branch 1221 and a fourth branch 1222, one end of the third branch 1221 is connected to the first interface 101 and the second interface 102, the other end of the third branch 1221 is connected to the eighth interface 108, one end of the fourth branch 1222 is connected to the ninth interface 109, and the other end of the fourth branch 1222 is connected to the second interface 102 and the third interface 103.

[0126] Specifically, one end of the third branch 1221 can be selectively connected to the first interface 101 or the second interface 102, the other end of the third branch 1221 is connected to the ninth port 71 through the eighth interface 108, one end of the fourth branch 1222 is connected to the tenth port 72 through the ninth interface 109, and the other end of the fourth branch 1222 is connected to the second interface 102 or the third interface 103, so that the refrigerant can enter from the first interface 101, flow through the refrigerator heat exchange circuit 122, and then flow back through the second interface 102, or enter from the third interface 103, flow through the refrigerator heat exchange circuit 122, and then flow back through the second interface 102.

[0127] Hence, see Figure 8 As shown, in the refrigerator cooling mode, the refrigerant flow path is compressor 20→external condenser 30→fourth branch 1222→ninth interface 109→tenth port 72→refrigerator assembly 70→ninth port 71→eighth interface 108→third branch 1221→second interface 102→compressor 20; in the refrigerator heating mode, the refrigerant flow path is compressor 20→first interface 101→third branch 1221→eighth interface 108→ninth port 71→refrigerator assembly 70→tenth port 72→ninth interface 109→fourth branch 1222→second interface 102→compressor 20.

[0128] It should be pointed out that the third branch 1221 can be connected to the first branch 1211 through the first connecting branch, or the third branch 1221 and the first connecting branch at least partially overlap, and the fourth branch 1222 can be connected to the second branch 1213 through the second connecting branch, or the fourth branch 1222 and the second connecting branch at least partially overlap, so that the third branch 1221 can be connected to the first interface 101 and the second interface 102, so that the fourth branch 1222 can be connected to the second interface 102 and the third interface 103, thereby realizing the refrigerator refrigeration and refrigerator heating functions of the thermal management system 100, and there is no need to make too many structural improvements on the integrated module 10, which can simplify the number of flow channel arrangements and the flow channel structure in the integrated module 10, and improve the reliability and stability of the thermal management system 100.

[0129] like Figure 2 As shown, further, the refrigerant side flow path 12 also includes: a fifth branch 123, one end of the fifth branch 123 is connected to the second branch 1213 and the fourth branch 1222, and the other end of the fifth branch 123 flows through the heat exchanger 11 and is connected to the second interface 102.

[0130] Specifically, the fifth branch 123 may include a first section and a second section, one end of the first section is connected to the refrigerant side inlet of the heat exchanger 11, and the other end of the first section is connected to the second branch 1213 and the fourth branch 1222, so that the refrigerant in the second branch 1213 or the fourth branch 1222 can enter the heat exchanger 11 through the first section and realize heat exchange in the heat exchanger 11, and one end of the second section is connected to the refrigerant side outlet of the heat exchanger 11, and the other end of the second section is connected to the second interface 102, so that the refrigerant that completes heat exchange in the heat exchanger 11 can flow back to the compressor 20 through the second section.

[0131] like Figure 2 As shown, further, a first solenoid valve 1231 and a first one-way valve 1232 are provided in the fifth branch 123. The first one-way valve 1232 is located upstream of the refrigerant side inlet of the heat exchanger 11 and is suitable for controlling the one-way flow of the refrigerant from the second branch 1213 and the fourth branch 1222 to the second interface 102.

[0132] As a result, the refrigerant for battery heating and refrigerator heating can further flow through the heat exchanger 11 and flow back to the compressor inlet 21, and the flow and pressure regulation of the fifth branch 123 can be achieved through the first solenoid valve 1231, and the one-way conduction function can be achieved through the first one-way valve 1232, that is, the refrigerant flowing into the third interface 103 can flow through the second branch 1213 and the fourth branch 1222 and flow back to the compressor 20, while the refrigerant entering the first interface 101 can not flow to the fifth branch 123 due to the cut-off effect of the one-way valve, thereby improving the safety of the integrated module 10 and reducing the probability of valve body leakage.

[0133] See also Figure 2 As shown, further, the refrigerant side flow path 12 also includes: a sixth branch 124 , one end of the sixth branch 124 is connected to the second branch 1213 and the fourth branch 1222 , and the other end of the sixth branch 124 is connected to the third interface 103 .

[0134] Specifically, the sixth branch 124 includes a third section and a fourth section, one end of the third section is connected to the third interface 103, the other end of the third section is connected to one end of the fourth section, the other end of the fourth section is connected to the second branch 1213 and the fourth pipeline (such as through the second connecting branch), and the fourth section is connected to the third section, part of the flow channel of the fifth branch 123 flowing out of the heat exchanger 11 and part of the flow channel of the fifth branch 123 connected to the second interface 102, so that the refrigerant flowing into the third interface 103 can be supplied to the second branch 1213 and / or the fourth branch 1222 through the fourth section, and can be supplied to the in-vehicle condenser 40 through at least part of the fifth branch 123, that is, at least part of the flow channel of the fifth branch 123 can be formed as a reused flow channel, that is, the refrigerant can be supplied to the second interface 102, and can also be supplied to the in-vehicle condenser 40, so as to further simplify the structure of the integrated module 10.

[0135] Furthermore, a second one-way valve 1241 and a third one-way valve 1242 are provided in the sixth branch 124. The second one-way valve 1241 is used to control the one-way flow of the refrigerant to the second branch 1213 and the fourth branch 1222. The third one-way valve 1242 is used to control the one-way connection between the external condenser 30 and the integrated module 10.

[0136] Specifically, the setting of the second one-way valve 1241 can prevent the refrigerant flowing into the third interface 103 from flowing back through the heat exchanger 11 to enter the second branch 1213 or the fourth branch 1222, while the setting of the third one-way valve 1242 can prevent the refrigerant from flowing back through the third interface 103 to enter the external condenser 30, so as to improve the safety and reliability of the integrated module 10.

[0137] exist Figure 2 In the illustrated embodiment, further, the refrigerant side flow path 12 also includes: a first trunk line 125 and a second trunk line 126, one end of the first trunk line 125 is connected to the first interface 101, the other end of the second trunk line 126 is connected to the first branch line 1211 and the third branch line 1221, one end of the second trunk line 126 is connected to the second interface 102, and the other end of the second trunk line 126 is connected to the second branch line 1213 and the fourth branch line 1222.

[0138] Exemplarily, there are two first branches 1211 and two second branches 1213, the two ends of the first connecting branch are respectively connected to the first trunk 125 and the second trunk 126, and the two ends are simultaneously connected to the two first branches 1211, and one end of the second trunk 126 is connected to the second interface 102, and the other end of the second trunk 126 is also connected to the first branch 1211, so that the first branch 1211 is connected to the first interface 101 and the second interface 102, the second trunk 126 is also connected to the fifth branch 123, the fifth branch 123 is simultaneously connected to the sixth branch 124 and the second branch 1213 and the fourth branch 1222, and the second branch 1213 is connected to the fourth branch 1222 via the second connecting branch.

[0139] Therefore, the settings of the first main circuit 125, the second main circuit 126, the first branch 1211, the second branch 1213, the third branch 1221, the fourth branch 1222, the fifth branch 123, and the sixth branch 124 can further enrich the working mode of the thermal management system 100, so that multiple functions such as battery cooling, battery heating, air conditioning refrigeration, and air conditioning heating can be performed in a composite and synchronous manner to improve the user experience.

[0140] Furthermore, the first main circuit 125 is provided with a second solenoid valve 1251, the second main circuit 126 is provided with a third solenoid valve 1261, and one end of the fifth branch 123 is located between the third solenoid valve 1261 and the second interface 102 to control the flow and on-off of the first main circuit 125 and the second main circuit 126. The setting position of the third battery valve makes it possible for the refrigerant returning from the fifth branch 123 to no longer flow through the third solenoid valve 1261, thereby reducing the flow resistance, extending the service life of the valve body, and improving the safety and reliability of the integrated module 10.

[0141] Furthermore, the refrigerant side flow path 12 also includes: an in-vehicle condenser 40 flow path in-vehicle condenser 40 loop, one end of the in-vehicle condenser 40 flow path in-vehicle condenser 40 loop is connected to the fourth interface 104, the other end of the in-vehicle condenser 40 flow path in-vehicle condenser 40 loop is connected to the fifth branch 123, and a second throttle valve 1281 is arranged in the in-vehicle condenser 40 flow path in-vehicle condenser 40 loop.

[0142] Therefore, the refrigerant flow rate of the in-vehicle condenser 40 flow path can be controlled by the second throttle valve 1281, and through the setting of the in-vehicle condenser 40, it can be selectively coordinated with the evaporator 50 to realize defrost mode, in-vehicle cooling and in-vehicle heating, etc., enriching the functions of the thermal management system 100.

[0143] like Figure 2As shown, in some embodiments, the refrigerant side flow path 12 also includes: a seventh branch 127, one end of the seventh branch 127 is connected to the fifth interface 105, the other end of the seventh branch 127 is connected to the fifth branch 123, and a third throttle valve 1271 is arranged in the seventh branch 127, and the third throttle valve 1271 is connected in parallel with the first solenoid valve 1231.

[0144] Thus, the refrigerant flowing into the third interface 103 can enter the evaporator 50 through the sixth branch 124, part of the fifth branch 123 and the seventh branch 127, and the refrigerant flowing into the fifth branch 123 can flow into the evaporator 50 through the seventh branch 127, thereby realizing at least partial flow channel reuse of the integrated module 10, further reducing the complexity of the flow channel of the integrated module 10, and simplifying the structure of the integrated module 10 and the thermal management system 100, reducing costs and improving reliability.

[0145] like Figure 1 and Figure 2 As shown, in some embodiments, the cooling medium side flow path 13 includes: a four-way valve 131, a water pump 132 and a water tank 133, the water tank 133 is connected to the water pump 132, the water pump 132 is connected to the cooling medium outlet of the heat exchanger 11, the cooling medium inlet of the heat exchanger 11 is connected to the first valve port of the four-way valve 131, and the second valve port is connected to the water pump 132.

[0146] Thus, the cooling medium side flow path 13 is formed through the four-way valve 131, the water pump 132 and the water tank 133 to realize the heat exchange between the cooling medium and the refrigerant.

[0147] According to some embodiments of the present application, it also includes: a motor radiator 80 and an oil-cooled heat exchange plate 90, the motor radiator 80 is connected to the tenth interface 110 and the eleventh interface 111 of the integrated module 10, the oil-cooled heat exchange plate is connected to the eleventh interface 111 and the twelfth interface 112, so that the motor radiator 80 and the oil-cooled heat exchange plate 90 are connected in series, and the fourth interface 104 is connected to the third valve port of the four-way valve 131, the eleventh interface 111 is connected to the fourth valve port, and the twelfth interface 112 is connected to the water pump 132.

[0148] Therefore, the cooling medium that participates in the heat exchange of the refrigerant by the heat exchanger 11 can also realize heat exchange for the motor and the motor controller, further improving the integration level of the thermal management system 100 and enriching the functions of the thermal management system 100.

[0149] Below, refer to Figure 3-Figure 16 The working mode of the thermal management system 100 according to the embodiment of the present application is described in detail.
