[0002] In related technologies, when regulating the temperature of vehicle interior components such as seats, some methods utilize semiconductors for thermoelectric cooling or heating, which has limited performance and high cost; others use refrigerants for temperature regulation, but this results in complex piping structures, high costs, and difficulties in maintenance or repair.

Utility Model Content

[0003] This utility model provides a vehicle thermal management system and a vehicle. The pipeline structure of the vehicle thermal management system is simple and the cost is low.

[0004] In a first aspect, this utility model provides a vehicle thermal management system, comprising: a compressor, a water-cooled condenser, a throttling component, a water-cooled cooler, a temperature-regulating branch, and a control valve assembly. The water-cooled condenser includes a first heat exchange path and a second heat exchange path that exchange heat with each other. The water-cooled cooler includes a third heat exchange path and a fourth heat exchange path that exchange heat with each other. The temperature-regulating branch includes a temperature-regulating pipe section and a water pump. The temperature-regulating pipe section is used to regulate the temperature of components installed in the vehicle. The compressor, the first heat exchange path, the throttling component, and the third heat exchange path... The circuits are connected in sequence to form a refrigerant circulation loop. The control valve assembly is connected to the second heat exchange flow path, the fourth heat exchange flow path, and the temperature regulating branch. The control valve assembly has a first state, a second state, and a third state. In the first state, the temperature regulating branch is connected to the second heat exchange flow path to form a coolant circulation loop. In the second state, the temperature regulating branch is connected to the fourth heat exchange flow path to form a coolant circulation loop. In the third state, the temperature regulating branch is disconnected from both the second and fourth heat exchange flow paths.

[0005] In the above technical solution, by sequentially connecting the compressor, the first heat exchange flow path, the throttling component, and the third heat exchange flow path to form a refrigerant circulation loop, the refrigerant can circulate within the loop. The refrigerant has different temperatures at different locations within the loop, and it can exchange heat with the coolant in corresponding components and other pipelines, allowing for cooling or heating as needed. Furthermore, by connecting the temperature-regulating branch of the control valve assembly to the second heat exchange flow path in its first state to form a coolant circulation loop, the coolant and refrigerant can exchange heat in the water-cooled condenser. At this point, the coolant heats up, providing heating for components installed inside the vehicle. In the second state, the temperature-regulating branch of the control valve assembly is connected to the fourth heat exchange flow path to form a coolant circulation loop, allowing the coolant and refrigerant to exchange heat in the water-cooled cooler. At this time, the coolant cools down to cool the components installed in the vehicle. In the third state, the temperature-regulating branch is isolated from both the second and fourth heat exchange flow paths, so that the temperature regulation of the components installed in the vehicle is closed. The control valve assembly can connect or disconnect the temperature-regulating branch with different heat exchange flow paths in different states. The pipeline structure design is simple, the cost is low, and the difficulty of pipeline maintenance or repair can be reduced.

[0006] In some embodiments, the water-cooled condenser has a first coolant inlet and a first coolant outlet, the second heat exchange flow path connects the first coolant inlet and the first coolant outlet, the water-cooled cooler has a second coolant inlet and a second coolant outlet, the fourth heat exchange flow path connects the second coolant inlet and the second coolant outlet, the temperature regulating branch has a branch inlet and a branch outlet, and the control valve assembly includes a plurality of valve ports, wherein the first coolant inlet, the first coolant outlet, the second coolant inlet, the second coolant outlet, the branch inlet, and the branch outlet are respectively connected to different valve ports of the control valve assembly.

[0007] In the above technical solution, by connecting the second heat exchange flow path to the first coolant inlet and the first coolant outlet, the coolant can exchange heat with the refrigerant in the water-cooled condenser when passing through the second heat exchange flow path, thereby increasing the coolant temperature. By connecting the fourth heat exchange flow path to the second coolant inlet and the second coolant outlet, the coolant can exchange heat with the refrigerant in the water-cooled cooler when passing through the fourth heat exchange flow path, thereby decreasing the coolant temperature. By connecting the first coolant inlet, the first coolant outlet, the second coolant inlet, the second coolant outlet, the branch inlet, and the branch outlet to different valve ports of the control valve assembly, the connection between the temperature regulating branch and different heat exchange flow paths can be changed simply by operating the control valve assembly. The temperature regulating branch can be controlled to heat, cool, or cut off the temperature as needed. The pipeline structure design is simple, the cost is low, and the difficulty of pipeline maintenance or repair can be reduced.

[0008] In some embodiments, the control valve assembly is a six-way valve, and the plurality of valve ports include a first valve port, a second valve port, a third valve port, a fourth valve port, a fifth valve port, and a sixth valve port. The first valve port is connected to the second coolant inlet, the second valve port is connected to the first coolant inlet, the third valve port is connected to the branch outlet, the fourth valve port is connected to the branch inlet, the fifth valve port is connected to the first coolant outlet, and the sixth valve port is connected to the second coolant outlet. In the first state, the second valve port is connected to the third valve port, and the fourth valve port is connected to the fifth valve port. In the second state, the first valve port is connected to the third valve port, and the fourth valve port is connected to the sixth valve port. In the third state, the third valve port is connected to the fourth valve port.

[0009] In the above technical solution, by connecting the first valve port to the third valve port and the fourth valve port to the sixth valve port in the first state, the branch outlet can be connected to the first coolant inlet, and the branch inlet can be connected to the first coolant outlet, thus connecting the temperature regulating branch to the second heat exchange flow path. After the coolant and refrigerant exchange heat in the water-cooled condenser, they flow into the temperature regulating branch, making the coolant in the temperature regulating branch a high-temperature coolant to heat the components installed in the vehicle. By connecting the second valve port to the third valve port and the fourth valve port in the second state, Connecting to the fifth valve port allows the branch outlet to connect to the second coolant inlet, and the branch inlet to connect to the second coolant outlet, thus connecting the temperature-regulating branch to the fourth heat exchange flow path. After heat exchange with the refrigerant in the water-cooled cooler, the coolant flows into the temperature-regulating branch, ensuring the coolant in the branch is at a low temperature to cool components installed in the vehicle. In the third state, connecting the third valve port to the fourth valve port isolates the temperature-regulating branch from the second and fourth heat exchange flow paths, cutting off temperature control of components installed in the vehicle. By using a six-way valve assembly, personnel can control the temperature-regulating branch for heating, cooling, or temperature control by operating only this six-way valve assembly when needed. This simplifies the piping design, reduces cost, and lowers the difficulty of pipe maintenance and repair.

[0010] In some embodiments, the control valve assembly includes two four-way valves, and the plurality of valve ports include a seventh valve port, an eighth valve port, a ninth valve port, and a tenth valve port disposed on one of the four-way valves, and an eleventh valve port, a twelfth valve port, a thirteenth valve port, and a fourteenth valve port disposed on the other four-way valve. The seventh valve port is connected to the first coolant inlet, the eighth valve port is connected to the branch outlet, the ninth valve port is connected to the eleventh valve port, the tenth valve port is connected to the first coolant outlet, the twelfth valve port is connected to the branch inlet, and the thirteenth valve port is connected to the first coolant outlet. The second coolant outlet is connected, and the fourteenth valve port is connected to the second coolant inlet; wherein, in the first state, the seventh valve port is connected to the eighth valve port, the ninth valve port is connected to the tenth valve port, and the eleventh valve port is connected to the twelfth valve port; in the second state, the eighth valve port is connected to the ninth valve port, the eleventh valve port is connected to the fourteenth valve port, and the twelfth valve port is connected to the thirteenth valve port; in the third state, the eighth valve port is connected to the ninth valve port, and the eleventh valve port is connected to the twelfth valve port.

[0011] In the above technical solution, by connecting the eighth valve port to the ninth valve port, the eleventh valve port to the fourteenth valve port, and the twelfth valve port to the thirteenth valve port in the first state, the branch inlet can be connected to the first coolant outlet, and the temperature regulating branch can be connected to the second heat exchange flow path. After the coolant and refrigerant exchange heat in the water-cooled condenser, they flow into the temperature regulating branch, making the coolant in the temperature regulating branch a high-temperature coolant to heat the components installed in the vehicle. In the second state, by connecting the seventh valve port to the eighth valve port, the ninth valve port to the tenth valve port, and the eleventh valve port to the thirteenth valve port, the branch inlet can be connected to the first coolant outlet, and the temperature regulating branch can be connected to the second heat exchange flow path. The twelfth valve port is connected, allowing the branch outlet to connect with the second coolant inlet and the branch inlet to connect with the second coolant outlet. This connects the temperature-regulating branch to the fourth heat exchange flow path. After heat exchange with the refrigerant in the water-cooled cooler, the coolant flows into the temperature-regulating branch, ensuring that the coolant in the branch is at a low temperature to cool the components installed in the vehicle. In the third state, the eighth and ninth valve ports are connected, and the eleventh and twelfth valve ports are connected. At this time, the temperature-regulating branch is isolated from the second and fourth heat exchange flow paths, cutting off the temperature regulation of the components installed in the vehicle. By using two four-way valves in the control valve assembly, personnel only need to operate the two four-way valves to control the temperature-regulating branch for heating, cooling, or temperature control when there is a need to cool, heat, or cut off the temperature regulation of the components installed in the vehicle. The pipeline structure design is simple, the cost is low, and the difficulty of pipeline maintenance or repair is reduced.

[0012] In some embodiments, the system includes at least one of a battery temperature regulating unit, an air conditioning unit, and a high-temperature radiator. When the vehicle thermal management system includes the battery temperature regulating unit, the battery temperature regulating unit is connected to at least one of the second heat exchange path and the fourth heat exchange path to form a battery temperature regulating circuit. When the vehicle thermal management system includes the air conditioning unit, the heating element of the air conditioning unit is connected to the second heat exchange path to form a warm air circuit, and the cooling element of the air conditioning unit is connected to the fourth heat exchange path to form a cold air circuit. When the vehicle thermal management system includes the high-temperature radiator, the high-temperature radiator is connected to the second heat exchange path to form a heat dissipation circuit.

[0013] In the above technical solution, when the vehicle thermal management system includes a battery temperature regulation unit, a battery temperature regulation loop can be formed by connecting the battery temperature regulation unit to at least one of the second heat exchange flow path and the fourth heat exchange flow path. The coolant in the battery temperature regulation loop exchanges heat with the refrigerant through the second or fourth heat exchange flow path and then regulates the temperature of the battery. This allows the vehicle thermal management system to simultaneously have the functions of regulating the temperature of the battery and the components installed in the vehicle.

[0014] When the vehicle thermal management system includes an air conditioning unit, the heating core of the air conditioning unit is connected to the second heat exchange flow path to form a warm air circuit, and the cooling core of the air conditioning unit is connected to the fourth heat exchange flow path to form a cold air circuit. When the air conditioning unit is in heating mode, the coolant in the warm air circuit is heated by heat exchange through the second heat exchange flow path and then enters the air conditioning unit to provide heating. When the air conditioning unit is in cooling mode, the coolant in the cold air circuit is cooled by heat exchange through the fourth heat exchange flow path and then enters the air conditioning unit to provide cooling. This vehicle thermal management system can simultaneously have the functions of air conditioning for cooling and heating and the function of adjusting the temperature of accessories installed in the vehicle.

[0015] When a vehicle thermal management system includes a high-temperature radiator, connecting the high-temperature radiator to a second heat exchange flow path forms a heat dissipation loop. The coolant in this loop exchanges heat and heats up in a water-cooled condenser through the second heat exchange flow path, then regulates the temperature of the high-temperature radiator. This allows the vehicle thermal management system to simultaneously perform air conditioning (cooling and heating) and temperature regulation of components installed in the vehicle. By further including at least one of a battery temperature regulation unit, an air conditioning unit, and a high-temperature radiator, the system can regulate the temperature of components installed in the vehicle as well as other components. Integrating the temperature regulation functions of multiple modules into the vehicle thermal management system fully leverages the integrability of water circuits, improving temperature regulation performance and reducing costs. Furthermore, it allows the vehicle thermal management system to meet the needs of different vehicle models.

One end of the second connecting pipe is connected to the fifth port and the other end is connected to the control valve assembly; the seventh port is connected to the second coolant inlet; one end of the third connecting pipe is connected to the eighth port and the other end is connected to the control valve assembly; the tenth port is connected to the second coolant outlet; one end of the fourth connecting pipe is connected to the eleventh port and the other end is connected to the control valve assembly; when the vehicle management system includes the battery temperature control unit, the third port and the sixth port are both connected to the battery temperature control unit to form a battery temperature control circuit and / or the ninth port and the twelfth port are both connected to the battery temperature control unit to form a battery temperature control circuit; when the vehicle management system includes the air conditioning unit, the third port and the sixth port are both connected to the heating element to form a warm air circuit, and the ninth port and the twelfth port are both connected to the cooling element to form a cold air circuit; when the vehicle management system includes the high-temperature radiator, the third port and the sixth port are both connected to the high-temperature radiator to form a heat dissipation circuit.

[0017] In the above technical solutions, when the vehicle management system includes a battery temperature regulation unit, by connecting both the third and sixth ports to the battery temperature regulation unit to form a battery temperature regulation circuit, the first coolant inlet tee pipe can connect the temperature regulation branch and the battery temperature regulation circuit together to the water-cooled condenser, and the first coolant outlet tee pipe can connect the heated pipe to the battery temperature regulation circuit and the temperature regulation branch. This allows the vehicle thermal management system to simultaneously have the functions of regulating battery temperature and regulating the temperature of components installed in the vehicle. And / or, when the vehicle management system includes a battery temperature regulation unit, by connecting both the ninth and twelfth ports to the battery temperature regulation unit to form a battery temperature regulation circuit, the second coolant inlet tee pipe can connect both the temperature regulation branch and the battery temperature regulation circuit together to the water-cooled condenser, and the second coolant outlet tee pipe can connect the cooled and heat-exchanged pipe to the battery temperature regulation circuit and the temperature regulation branch. This allows the vehicle thermal management system to simultaneously have the functions of regulating battery temperature and regulating the temperature of components installed in the vehicle.

[0018] When the vehicle management system includes an air conditioning unit, the third and sixth ports are connected to the heating core to form a warm air circuit, and the ninth and twelfth ports are connected to the cooling core to form a cold air circuit. This allows the first coolant inlet tee to connect the temperature control branch and the heating circuit of the air conditioning unit to the water-cooled condenser. The first coolant outlet tee connects the heated pipe to the temperature control branch and the heating circuit of the air conditioning unit. The second coolant inlet tee connects the temperature control branch and the cooling circuit of the air conditioning unit to the water-cooled condenser. The second coolant outlet tee connects the cooled and heat-exchanged pipe to the cooling circuit and the temperature control branch of the air conditioning unit. This allows the vehicle thermal management system to simultaneously provide air conditioning heating and cooling functions as well as temperature control for components installed in the vehicle.

[0019] When the vehicle management system includes a high-temperature radiator, both the third and sixth ports are connected to the high-temperature radiator to form a heat dissipation circuit. This allows the first coolant inlet tee to connect the temperature regulation branch and the heating circuit of the high-temperature radiator to the water-cooled condenser, and the first coolant outlet tee to connect the heated pipe to the temperature regulation branch and the heating circuit of the high-temperature radiator. This allows the vehicle thermal management system to simultaneously function as a high-temperature radiator and to regulate the temperature of components installed in the vehicle.

[0020] By including multiple T-junctions in the vehicle thermal management system, the second heat exchange path can be shared by multiple pipelines. This allows the vehicle to regulate the temperature of in-vehicle components as well as other parts, integrating the temperature regulation functions of multiple modules into the vehicle thermal management system. This fully leverages the integrability of water circuits, improves temperature regulation performance, and reduces costs. Furthermore, the pipeline design is relatively simple, enabling the vehicle thermal management system to meet the needs of different vehicle models.

[0055] In this utility model, "multiple" refers to two or more (including two).

[0056] In related technologies, when regulating the temperature of vehicle interior components such as seats, some methods utilize semiconductors for thermoelectric cooling or heating, which has limited performance and high cost; others use refrigerants for temperature regulation, but this results in complex piping structures, high costs, and difficulties in maintenance or repair. Therefore, simplifying the piping structure and reducing costs are technical challenges that need to be addressed when implementing temperature regulation for vehicle interior components.

[0057] Based on this, the applicant proposes a vehicle thermal management system, including: a compressor, a water-cooled condenser, a throttling device, a water-cooled cooler, a temperature regulating branch, and a control valve assembly. The water-cooled condenser includes a first heat exchange path and a second heat exchange path that exchange heat with each other. The water-cooled cooler includes a third heat exchange path and a fourth heat exchange path that exchange heat with each other. The temperature regulating branch includes a temperature regulating pipe section and a water pump. The temperature regulating pipe section is used for installation in vehicle-mounted components. The compressor, the first heat exchange path, the throttling device, and the third heat exchange path are arranged in a specific manner... The control valve assembly is connected to the second heat exchange path, the fourth heat exchange path, and the temperature regulating branch to form a refrigerant circulation loop. The control valve assembly has a first state, a second state, and a third state. In the first state, the temperature regulating branch is connected to the second heat exchange path to form a coolant circulation loop. In the second state, the temperature regulating branch is connected to the fourth heat exchange path to form a coolant circulation loop.

[0058] The aforementioned vehicle thermal management system, by sequentially connecting the compressor, the first heat exchange path, the throttling component, and the third heat exchange path to form a refrigerant circulation loop, allows the refrigerant to circulate within this loop. The refrigerant reaches different temperatures at different locations within the loop and can exchange heat with the coolant in corresponding components and other pipelines, enabling cooling or heating as needed. Furthermore, by connecting the temperature-regulating branch of the control valve assembly to the second heat exchange path in its first state to form a coolant circulation loop, the coolant and refrigerant exchange heat in the water-cooled condenser. This raises the coolant temperature, providing heating for components installed inside the vehicle. In the second state, the temperature-regulating branch of the control valve assembly is connected to the fourth heat exchange flow path to form a coolant circulation loop, allowing the coolant and refrigerant to exchange heat in the water-cooled cooler. At this time, the coolant cools down to cool the components installed in the vehicle. In the third state, the temperature-regulating branch is isolated from both the second and fourth heat exchange flow paths, so that the temperature regulation of the components installed in the vehicle is closed. The control valve assembly can connect or disconnect the temperature-regulating branch with different heat exchange flow paths in different states. The pipeline structure design is simple, the cost is low, and the difficulty of pipeline maintenance or repair can be reduced.

[0059] The vehicles disclosed in this utility model embodiment can be fuel vehicles, natural gas vehicles, new energy vehicles or rail vehicles. New energy vehicles can be pure electric vehicles, hybrid vehicles or range-extended vehicles, etc.

[0063] The compressor 10, the first heat exchange flow path 13, the throttling component 11, and the third heat exchange flow path 22 are connected in sequence to form a refrigerant circulation loop. After being compressed by the compressor 10, the refrigerant flows into the first heat exchange flow path 13, where it exchanges heat with the coolant in the second heat exchange flow path 14 in the water-cooled condenser 12. Then, it passes through the throttling component 11 and flows into the third heat exchange flow path 22, where it exchanges heat with the coolant in the fourth heat exchange flow path 23 in the water-cooled cooler 21. Finally, it flows back into the compressor 10, forming a refrigerant circulation loop.

[0064] In the first state, the temperature regulating branch 30 is connected to the second heat exchange flow path 14 to form a coolant circulation loop, and the temperature regulating branch 30 is isolated from the fourth heat exchange flow path 23. In the second heat exchange flow path 14, the coolant exchanges heat with the refrigerant in the first heat exchange flow path 13 in the water-cooled condenser 12, and then enters the temperature regulating branch 30 through the control valve assembly 40 to regulate the temperature of the component 70 installed in the vehicle. Then the coolant flows back to the second heat exchange flow path 14 through the control valve assembly 40, forming the coolant circulation in the first state of the control valve.

[0065] In the second state, the temperature regulating branch 30 is connected to the fourth heat exchange flow path 23 to form a coolant circulation loop, and the temperature regulating branch 30 is isolated from the second heat exchange flow path 14. The coolant in the fourth heat exchange flow path 23 exchanges heat with the refrigerant in the third heat exchange flow path 22 in the water-cooled cooler 21, and then enters the temperature regulating branch 30 through the control valve assembly 40 to regulate the temperature of the component 70 installed in the vehicle. Then the coolant flows back to the second heat exchange flow path 14 through the control valve assembly 40, forming the coolant circulation of the control valve in the second state.

[0066] In the third state, since the temperature regulating branch 30 is isolated from the second heat exchange flow path 14 and the fourth heat exchange flow path 23, the coolant in the second heat exchange flow path 14 or the fourth heat exchange flow path 23 cannot flow into the temperature regulating branch 30. At this time, the temperature regulation of the accessory 70 installed in the vehicle is in the off state.

[0067] In the above technical solution, by sequentially connecting the compressor 10, the first heat exchange flow path 13, the throttling component 11, and the third heat exchange flow path 22 to form a refrigerant circulation loop, the refrigerant can circulate in the refrigerant circulation loop. The refrigerant has different temperatures at different positions in the refrigerant circulation loop, and can exchange heat with the coolant in corresponding components and other pipelines, allowing for cooling or heating as needed. By connecting the temperature regulating branch 30 to the second heat exchange flow path 14 in the first state of the control valve assembly 40 to form a coolant circulation loop, the coolant and refrigerant can exchange heat in the water-cooled condenser, at which point the coolant heats up, providing heat to the component 70 installed in the vehicle. In the second state, the temperature regulating branch 30 of the control valve assembly 40 is connected to the fourth heat exchange flow path 23 to form a coolant circulation loop, allowing the coolant and refrigerant to exchange heat in the water-cooled cooler. At this time, the coolant cools down to cool the component 70 installed in the vehicle. In the third state, the temperature regulating branch 30 is isolated from both the second heat exchange flow path 14 and the fourth heat exchange flow path 23, so that the temperature regulation of the component 70 installed in the vehicle is closed. The control valve assembly 40 can connect or disconnect the temperature regulating branch 30 with different heat exchange flow paths in different states. The pipeline structure design is simple, the cost is low, and the difficulty of pipeline maintenance or repair can be reduced.

[0068] In some embodiments, refer to Figures 1-6 The water-cooled condenser 12 has a first coolant inlet 15 and a first coolant outlet 16. The second heat exchange flow path 14 connects the first coolant inlet 15 and the first coolant outlet 16. The water-cooled cooler 21 has a second coolant inlet 24 and a second coolant outlet 25. The fourth heat exchange flow path 23 connects the second coolant inlet 24 and the second coolant outlet 25. The temperature regulating branch 30 has a branch inlet 31 and a branch outlet 32. The control valve assembly 40 includes multiple valve ports. The first coolant inlet 15, the first coolant outlet 16, the second coolant inlet 24, the second coolant outlet 25, the branch inlet 31, and the branch outlet 32 ​​are respectively connected to different valve ports of the control valve assembly 40.

[0069] In the above technical solution, by connecting the second heat exchange flow path 14 to the first coolant inlet 15 and the first coolant outlet 16, the coolant can exchange heat with the refrigerant in the water-cooled condenser 12 when passing through the second heat exchange flow path 14, thereby increasing the coolant temperature. Similarly, by connecting the fourth heat exchange flow path 23 to the second coolant inlet 24 and the second coolant outlet 25, the coolant can exchange heat with the refrigerant in the water-cooled cooler 21 when passing through the fourth heat exchange flow path 23, thereby increasing the coolant temperature. The temperature is reduced; by connecting the first coolant inlet 15, the first coolant outlet 16, the second coolant inlet 24, the second coolant outlet 25, the branch inlet 31, and the branch outlet 32 ​​to different valve ports of the control valve assembly 40, the connection between the temperature regulating branch 30 and different heat exchange flow paths can be changed by operating the control valve assembly 40. The temperature regulating branch 30 can be controlled to heat, cool, or cut off the temperature as needed. The pipeline structure design is simple, the cost is low, and the difficulty of pipeline maintenance or repair can be reduced.

[0070] In some embodiments, refer to Figures 1-3 The control valve assembly 40 is a six-way valve with multiple valve ports including a first valve port 41, a second valve port 42, a third valve port 43, a fourth valve port 44, a fifth valve port 45, and a sixth valve port 46. The first valve port 41 is connected to the second coolant inlet 24, the second valve port 42 is connected to the first coolant inlet 15, the third valve port 43 is connected to the branch outlet 32, the fourth valve port 44 is connected to the branch inlet 31, the fifth valve port 45 is connected to the first coolant outlet 16, and the sixth valve port 46 is connected to the second coolant outlet 25. In the first state, the second valve port 42 is connected to the third valve port 43, and the fourth valve port 44 is connected to the fifth valve port 45. In the second state, the first valve port 41 is connected to the third valve port 43, and the fourth valve port 44 is connected to the sixth valve port 46. In the third state, the third valve port 43 is connected to the fourth valve port 44.

[0071] In the first state, the second valve port 42 is connected to the third valve port 43, the fourth valve port 44 is connected to the fifth valve port 45, and the temperature regulating branch 30 is connected to the second heat exchange flow path 14 to form a coolant circulation loop. In the second heat exchange flow path 14, the coolant exchanges heat with the refrigerant in the first heat exchange flow path 13 in the water-cooled condenser 12. Then, it leaves the water-cooled condenser 12 from the first coolant outlet 16, enters the control valve assembly 40 through the fifth valve port 45, leaves the control valve assembly 40 from the fourth valve port 44 and enters the branch inlet 31 of the temperature regulating branch 30 to regulate the temperature of the component 70 installed in the vehicle. Then, the coolant enters the control valve assembly 40 through the branch outlet 32 ​​and the third valve port 43, leaves the control valve assembly 40 from the second valve port 42, and flows into the first coolant inlet 15 to prepare for another heat exchange, forming the coolant circulation of the control valve in the first state.

[0072] In the second state, the first valve port 41 is connected to the third valve port 43, the fourth valve port 44 is connected to the sixth valve port 46, and the temperature regulating branch 30 is connected to the fourth heat exchange flow path 23 to form a coolant circulation loop. In the fourth heat exchange flow path 23, the coolant exchanges heat with the refrigerant in the third heat exchange flow path 22 in the water-cooled condenser 12. Then, it leaves the water-cooled condenser 12 from the second coolant outlet 25, enters the control valve assembly 40 through the sixth valve port 46, leaves the control valve assembly 40 from the fourth valve port 44, and enters the branch inlet 31 of the temperature regulating branch 30 to regulate the temperature of the component 70 installed in the vehicle. Then, the coolant enters the control valve assembly 40 through the branch outlet 32, enters the control valve assembly 40 through the third valve port 43, leaves the control valve assembly 40 from the first valve port 41, and flows into the second coolant inlet 24 to prepare for another heat exchange, forming the coolant circulation of the control valve in the second state.

[0073] In the third state, the third valve port 43 is connected to the fourth valve port 44, and the temperature regulating branch 30 is isolated from the second heat exchange flow path 14 and the fourth heat exchange flow path 23. The coolant in the second heat exchange flow path 14 or the fourth heat exchange flow path 23 cannot flow into the temperature regulating branch 30. At this time, the temperature regulation of the accessory 70 installed in the vehicle is in the closed state.

[0074] In the above technical solution, by connecting the first valve port 41 to the third valve port 43 and the fourth valve port 44 to the sixth valve port 46 in the first state, the branch outlet 32 ​​can be connected to the first coolant inlet 15, and the branch inlet can be connected to the first coolant outlet 16, thus connecting the temperature regulating branch 30 to the second heat exchange flow path 14. After the coolant and refrigerant exchange heat in the water-cooled condenser 12, they flow into the temperature regulating branch 30, making the coolant in the temperature regulating branch 30 a high-temperature coolant to heat the components 70 installed in the vehicle. By connecting the second valve port 42 to the third valve port 43 and the fourth valve port 44 in the second state, the branch outlet 32 ​​can be connected to the first coolant inlet 15, and the branch inlet can be connected to the first coolant outlet 16, thus connecting the temperature regulating branch 30 to the second heat exchange flow path 14. Connecting to the fifth valve port 45 allows the branch outlet 32 ​​to connect to the second coolant inlet 24, and the branch inlet to connect to the second coolant outlet 25, thus connecting the temperature-regulating branch 30 to the fourth heat exchange flow path 23. After heat exchange with the refrigerant in the water-cooled cooler 21, the coolant flows into the temperature-regulating branch 30, ensuring the coolant in the branch is at a low temperature to cool the components 70 installed in the vehicle. In the third state, connecting the third valve port 43 to the fourth valve port 44 isolates the temperature-regulating branch 30 from the second and fourth heat exchange flow paths 14 and 23, cutting off the temperature regulation of the components 70 installed in the vehicle. By using a six-way valve assembly 40, personnel can control the temperature-regulating branch 30 for heating, cooling, or temperature control by operating only this six-way valve assembly when needed. This simplifies the piping structure design, reduces cost, and lowers the difficulty of pipe maintenance and repair.

[0075] In some embodiments, refer to Figures 4-6 The control valve assembly 40 includes two four-way valves, with multiple valve ports including a seventh valve port 47, an eighth valve port 48, a ninth valve port 49, and a tenth valve port 50 on one of the four-way valves, and an eleventh valve port 51, a twelfth valve port 52, a thirteenth valve port 53, and a fourteenth valve port 54 on the other four-way valve. The seventh valve port 47 is connected to the first coolant inlet 15, the eighth valve port 48 is connected to the branch outlet 32, the ninth valve port 49 is connected to the eleventh valve port 51, the tenth valve port 50 is connected to the first coolant outlet 16, the twelfth valve port 52 is connected to the branch inlet 31, and the thirteenth valve port 54 is connected to the branch outlet 32. Port 53 is connected to the second coolant outlet 25, and the fourteenth valve port 54 is connected to the second coolant inlet 24. In the first state, the seventh valve port 47 is connected to the eighth valve port 48, the ninth valve port 49 is connected to the tenth valve port 50, and the eleventh valve port 51 is connected to the twelfth valve port 52. In the second state, the eighth valve port 48 is connected to the ninth valve port 49, the eleventh valve port 51 is connected to the fourteenth valve port 54, and the twelfth valve port 52 is connected to the thirteenth valve port 53. In the third state, the eighth valve port 48 is connected to the ninth valve port 49, and the eleventh valve port 51 is connected to the twelfth valve port 52.

[0076] In the first state, the eighth valve port 48 is connected to the ninth valve port 49, the eleventh valve port 51 is connected to the fourteenth valve port 54, the twelfth valve port 52 is connected to the thirteenth valve port 53, and the temperature regulating branch 30 is connected to the second heat exchange flow path 14 to form a coolant circulation loop. In the second heat exchange flow path 14, the coolant exchanges heat with the refrigerant in the first heat exchange flow path 13 in the water-cooled condenser 12, and then leaves the water-cooled condenser 12 from the first coolant outlet 16, entering a four-valve cycle through the tenth valve port 50. The coolant exits the four-way valve through the ninth valve port 49, then enters another four-way valve through the eleventh valve port 51, exits another four-way valve through the twelfth valve port 52, and enters the branch inlet 31 of the temperature regulating branch 30 to regulate the temperature of the component 70 installed in the vehicle. Subsequently, the coolant enters the four-way valve through the branch outlet 32, through the eighth valve port 48, exits the four-way valve through the seventh valve port 47, and flows into the first coolant inlet 15 to prepare for another heat exchange, forming the coolant circulation in the first state of the control valve.

[0077] In the second state, the eighth valve port 48 is connected to the ninth valve port 49, the eleventh valve port 51 is connected to the fourteenth valve port 54, the twelfth valve port 52 is connected to the thirteenth valve port 53, and the temperature regulating branch 30 is connected to the fourth heat exchange flow path 23 to form a coolant circulation loop. In the fourth heat exchange flow path 23, the coolant exchanges heat with the refrigerant in the third heat exchange flow path 22 in the water-cooled condenser 12, and then leaves the water-cooled condenser 12 from the second coolant outlet 25 and enters the four-way valve through the thirteenth valve port 53. The coolant exits the four-way valve from the twelfth valve port 52 and enters the branch inlet 31 of the temperature regulating branch 30 to regulate the temperature of the component 70 installed in the vehicle. Then, the coolant passes through the branch outlet 32, enters a four-way valve through the eighth valve port 48, exits the four-way valve from the ninth valve port 49, enters another four-way valve through the eleventh valve port 51, exits the other four-way valve from the fourteenth valve port 54, and flows into the second coolant inlet 24 to prepare for another heat exchange, forming a coolant circulation in the second state of the control valve.

[0078] In the third state, the eighth valve port 48 is connected to the ninth valve port 49, and the eleventh valve port 51 is connected to the twelfth valve port 52. The temperature regulating branch 30 is isolated from the second heat exchange flow path 14 and the fourth heat exchange flow path 23. The coolant in the second heat exchange flow path 14 or the fourth heat exchange flow path 23 cannot flow into the temperature regulating branch 30. At this time, the temperature regulation of the accessory 70 installed in the vehicle is in the closed state.

[0079] In the above technical solution, by connecting the eighth valve port 48 to the ninth valve port 49, the eleventh valve port 51 to the fourteenth valve port 54, and the twelfth valve port 52 to the thirteenth valve port 53 in the first state, the branch inlet can be connected to the first coolant outlet 16, and the temperature regulating branch 30 can be connected to the second heat exchange flow path 14. After the coolant and refrigerant exchange heat in the water-cooled condenser 12, they flow into the temperature regulating branch 30, which can make the coolant in the temperature regulating branch 30 a high-temperature coolant to heat the parts 70 installed in the vehicle; by connecting the seventh valve port 47 to the eighth valve port 48, the ninth valve port 49 to the tenth valve port 50, and the eleventh valve port 51 to the thirteenth valve port 53 in the second state, the branch inlet can be connected to the first coolant outlet 16, and the temperature regulating branch 30 can be connected to the second heat exchange flow path 14. The twelfth valve port 52 is connected, which connects the branch outlet 32 ​​with the second coolant inlet 24 and the branch inlet with the second coolant outlet 25, thus connecting the temperature regulating branch 30 with the fourth heat exchange flow path 23. After the coolant and refrigerant exchange heat in the water-cooled cooler 21, they flow into the temperature regulating branch 30, which makes the coolant in the temperature regulating branch 30 a low-temperature coolant, cooling the component 70 installed in the vehicle. In the third state, the eighth valve port 48 is connected with the ninth valve port 49, and the eleventh valve port 51 is connected with the twelfth valve port 52. At this time, the temperature regulating branch 30 is isolated from the second heat exchange flow path 14 and the fourth heat exchange flow path 23, which can cut off the temperature regulation of the component 70 installed in the vehicle. By making the control valve assembly 40 into two four-way valves, when relevant personnel have a need for cooling, heating, or temperature control of the accessories 70 installed in the vehicle, they only need to operate the two four-way valves to control the temperature control branch 30 to heat, cool, or cut off the temperature. The pipeline structure design is simple, the cost is low, and the difficulty of pipeline maintenance or repair can be reduced.

[0080] In some embodiments, refer to Figures 1-6 The vehicle thermal management system 100 includes at least one of a battery temperature regulation unit, an air conditioning unit, and a high-temperature radiator. When the vehicle thermal management system 100 includes a battery temperature regulation unit, the battery temperature regulation unit is connected to at least one of a second heat exchange flow path 14 and a fourth heat exchange flow path 23 to form a battery temperature regulation circuit. When the vehicle thermal management system 100 includes an air conditioning unit, the heating core of the air conditioning unit is connected to the second heat exchange flow path 14 to form a warm air circuit, and the cooling core of the air conditioning unit is connected to the fourth heat exchange flow path 23 to form a cold air circuit. When the vehicle thermal management system 100 includes a high-temperature radiator, the high-temperature radiator is connected to the second heat exchange flow path 14 to form a heat dissipation circuit.

[0081] The vehicle thermal management system 100 includes at least one of a battery temperature regulation unit, an air conditioning unit, and a high-temperature radiator, comprising: the vehicle thermal management system 100 including a battery temperature regulation unit; the vehicle thermal management system 100 including an air conditioning unit; the vehicle thermal management system 100 including a high-temperature radiator; the vehicle thermal management system 100 including a battery temperature regulation unit and an air conditioning unit; the vehicle thermal management system 100 including a battery temperature regulation unit and a high-temperature radiator; the vehicle thermal management system 100 including an air conditioning unit and a high-temperature radiator; the vehicle thermal management system 100 including a battery temperature regulation unit, an air conditioning unit, and a high-temperature radiator.

[0082] When the vehicle thermal management system 100 includes a battery temperature regulation unit, the connection of the battery temperature regulation unit to at least one of the second heat exchange flow path 14 and the fourth heat exchange flow path 23 includes: the battery temperature regulation unit being connected to the second heat exchange flow path 14; the battery temperature regulation unit being connected to the fourth heat exchange flow path 23; and the battery temperature regulation unit being connected to both the second heat exchange flow path 14 and the fourth heat exchange flow path 23.

[0083] In the above technical solution, when the vehicle thermal management system 100 includes a battery temperature regulation unit, a battery temperature regulation circuit can be formed by connecting the battery temperature regulation unit to at least one of the second heat exchange flow path 14 and the fourth heat exchange flow path 23. The coolant in the battery temperature regulation circuit exchanges heat with the refrigerant through the second heat exchange flow path 14 or the fourth heat exchange flow path 23 and then regulates the temperature of the battery. This allows the vehicle thermal management system 100 to simultaneously have the functions of regulating the temperature of the battery and the temperature of the accessories 70 installed in the vehicle.

[0084] When the vehicle thermal management system 100 includes an air conditioning unit, the heating core of the air conditioning unit is connected to the second heat exchange flow path 14 to form a warm air circuit, and the cooling core of the air conditioning unit is connected to the fourth heat exchange flow path 23 to form a cold air circuit. When the air conditioning unit is in heating mode, the coolant in the warm air circuit is heated by heat exchange through the second heat exchange flow path 14 and then enters the air conditioning unit to provide heating. When the air conditioning unit is in cooling mode, the coolant in the cold air circuit is cooled by heat exchange through the fourth heat exchange flow path 23 and then enters the air conditioning unit to provide cooling. The vehicle thermal management system 100 can simultaneously have the functions of air conditioning for cooling and heating and the function of adjusting the temperature of the accessories 70 installed in the vehicle.

[0085] When the vehicle thermal management system 100 includes a high-temperature radiator, a heat dissipation circuit can be formed by connecting the high-temperature radiator to the second heat exchange flow path 14. The coolant in the heat dissipation circuit exchanges heat and rises in the water-cooled condenser 12 through the second heat exchange flow path 14, and then regulates the temperature of the high-temperature radiator. This allows the vehicle thermal management system 100 to simultaneously have the functions of air conditioning (cooling and heating) and temperature regulation of the components 70 installed in the vehicle. By including at least one of a battery temperature regulation unit, an air conditioning unit, and a high-temperature radiator in the vehicle thermal management system 100, it can regulate the temperature of the components 70 installed in the vehicle while also providing temperature regulation for other components. This integrates the temperature regulation functions of multiple modules into the vehicle thermal management system 100, fully leveraging the advantages of water circuit integration, improving temperature regulation performance, and reducing costs. Furthermore, the vehicle thermal management system 100 can meet the needs of different vehicle models.

[0086] In some embodiments, refer to Figures 1-6The water-cooled condenser 12 has a first coolant inlet 15 and a first coolant outlet 16.

[0087] Wherein, when the vehicle thermal management system 100 includes a battery temperature regulation unit, the third port 193 and the sixth port 203 are both connected to the battery temperature regulation unit to form a battery temperature regulation circuit and / or the ninth port 283 and the twelfth port 293 are both connected to the battery temperature regulation unit to form a battery temperature regulation circuit, including: the third port 193 and the sixth port 203 are both connected to the battery temperature regulation unit to form a battery temperature regulation circuit; the ninth port 283 and the twelfth port 293 are both connected to the battery temperature regulation unit to form a battery temperature regulation circuit; the third port 193 and the sixth port 203 are both connected to the battery temperature regulation unit to form a battery temperature regulation circuit, and the ninth port 283 and the twelfth port 293 are both connected to the battery temperature regulation unit to form a battery temperature regulation circuit.

[0088] When the vehicle thermal management system 100 includes a battery temperature regulation unit, and the third port 193 and the sixth port 203 are both connected to the battery temperature regulation unit to form a battery temperature regulation circuit, the coolant after being regulated by the temperature regulation unit enters the first coolant inlet tee pipe 19 from the third port 193, then exits the first coolant inlet tee pipe 19 from the first port 191, flows into the first coolant inlet 15 and enters the second heat exchange flow path 14. After exchanging heat with the refrigerant in the water-cooled condenser 12 and being heated, it enters the first coolant outlet tee pipe 20 from the fourth port 201 through the first coolant outlet 16, and then exits the first coolant outlet tee pipe 20 from the sixth port 203 to regulate the temperature of the battery temperature regulation unit, thereby increasing the ambient temperature of the battery and enabling the battery to start up faster or operate better.

[0089] When the vehicle thermal management system 100 includes a battery temperature regulation unit, and the ninth port 283 and the twelfth port 293 are both connected to the battery temperature regulation unit to form a battery temperature regulation circuit, the coolant after being regulated by the temperature regulation unit enters the second coolant inlet tee pipe 28 from the ninth port 283, then exits the second coolant inlet tee pipe 28 from the eleventh port 292, flows into the second coolant inlet 24 and enters the fourth heat exchange flow path 23. After exchanging heat with the refrigerant and cooling down in the water-cooled cooler 21, it enters the second coolant outlet tee pipe 29 from the fourteenth port through the second coolant outlet 25, and then exits the second coolant outlet tee pipe 29 from the twelfth port 293 to regulate the temperature of the battery temperature regulation unit, thereby reducing the ambient temperature when the battery is working, avoiding excessively high battery temperature and reduced efficiency, and improving the safety performance of the battery.

[0090] When the vehicle thermal management system 100 includes an air conditioning unit, the third port 193 and the sixth port 203 are both connected to the heating core to form a warm air circuit, and the ninth port 283 and the twelfth port 293 are both connected to the cooling core to form a cold air circuit. When the air conditioner is in heating mode, the coolant after temperature adjustment enters the first coolant inlet tee pipe 19 from the third port 193, then exits the first coolant inlet tee pipe 19 from the first port 191, flows into the first coolant inlet 15 and enters the second heat exchange path 14. After exchanging heat with the refrigerant in the water-cooled condenser 12 and being heated, it enters the first coolant outlet tee pipe 20 from the fourth port 201 through the first coolant outlet 16, and then exits the first coolant outlet tee pipe 20 from the sixth port 203 and adjusts the temperature of the air conditioner, causing the air conditioner to blow out hot air, raising the temperature inside the vehicle 200 and improving comfort.

[0091] When the air conditioner is in cooling mode, the coolant, after being regulated to adjust the temperature of the air conditioner, enters the second coolant inlet tee pipe 28 from the ninth port 283, then exits the second coolant inlet tee pipe 28 from the eleventh port 292, flows into the second coolant inlet 24 and enters the fourth heat exchange flow path 23.
