[0034] Hereinafter, the embodiments of the present disclosure will be described in detail. Examples of the embodiments are shown in the accompanying drawings, and the same or similar reference numerals in all the accompanying drawings indicate the same or similar components or components having the same or similar functions. The embodiments described below with reference to the accompanying drawings are illustrative and are intended to explain the present disclosure, but cannot be construed as limiting the present disclosure.

[0035] An integrated module 1 according to an embodiment of the present disclosure will now be described with reference to FIGS.

[0036] 1 , an integrated module 1 according to the present disclosure includes a first flow path plate 10, a second flow path plate 20, and a heat exchanger 30. A plurality of refrigerant flow paths are disposed within the first flow path plate 10, and the first flow path plate 10 is provided with a first heat exchanger interface 15, a second heat exchanger interface 16, and a plurality of external device interfaces, each of which is connected to a corresponding refrigerant flow path, and each external device interface is configurable to connect to a component within a thermal management system 10000 of a vehicle 1000. A second flow path plate 20 is fixed to the first flow path plate 10, and an internal liquid cooling flow path is disposed within the second flow path plate 20, and the second flow path plate 20 is provided with a third heat exchanger interface 23, a fourth heat exchanger interface 24, and a first water-side interface 21. The third heat exchanger interface 23, the fourth heat exchanger interface 24 and the first water side interface 21 are respectively connected to corresponding internal liquid cooling channels, and the first water side interface 21 can be configured to be connected to an external motor electronic control radiator 500. The heat exchanger 30 is fixed to at least one of the first channel plate 10 and the second channel plate 20. The heat exchanger 30 is provided with a first heat exchange channel and a second heat exchange channel that exchange heat with each other, and both ends of the first heat exchange channel are connected to the first heat exchanger interface 15 and the second heat exchanger interface 16, respectively, and both ends of the second heat exchange channel are connected to the third heat exchanger interface 23 and the fourth heat exchanger interface 24, respectively.

[0037] In some embodiments, the integrated module 1 can be applied to a thermal management system 10000 of a vehicle 1000. The integrated module 1 integrates and arranges control components of the thermal management system 10000. Increasing the level of integration of the integrated module 1 can significantly reduce the space occupied by the thermal management system 10000 within the vehicle. The integrated module 1 includes a first flow path plate 10 and a second flow path plate 20. The first flow path plate 10 has multiple refrigerant flow paths formed therein, and the second flow path plate 20 has internal liquid cooling flow paths formed therein. The first flow path plate 10 has multiple external device interfaces and is connected to various components of the vehicle thermal management system 10000 via the multiple external device interfaces. The second flow path plate 20 is fixed to the first flow path plate 10. The second flow path plate 20 has a first water-side interface 21. The first water-side interface 21 is connected to the motor electronic control radiator 500 so that the refrigerant can pass through the motor electronic control radiator 500 and exchange heat with the motor electronic control radiator 500. The heat exchanger 30 has a first heat exchange flow path and a second heat exchange flow path that exchange heat with each other. The first heat exchange flow path is connected to a first heat exchanger interface 15 and a second heat exchanger interface 16 on the first flow path plate 10, which are connected to the refrigerant flow path, respectively. The second heat exchange flow path is connected to a third heat exchanger interface 23 and a fourth heat exchanger interface 24 on the second flow path plate 20, which are connected to the internal liquid cooling flow path, respectively. The heat exchanger 30 can realize heat exchange between the refrigerant flow path and the internal liquid cooling flow path. In some embodiments, the refrigerant can flow through the refrigerant flow path in each refrigerant circuit of the thermal management system 10000 through the refrigerant flow path in the first flow path plate 10. The first flow path plate 10 is connected to a structure through which the refrigerant flows, and together with the structure, they form a refrigerant-side integrated module. The second flow path plate 20 is connected to a structure through which the refrigerant flows, and together with these structures, they form a liquid-cooling-side integrated module.

[0038] According to the integrated module 1 of the present disclosure, by connecting the first flow path plate 10 and the second flow path plate 20, the structure located on the integrated module 1 is divided into a refrigerant side and a liquid-cooled side. Meanwhile, because the refrigerant side integrated module and the liquid-cooled side integrated module exchange heat via the heat exchanger 30, the overall layout space of the integrated module 1 can be reduced. By integrating the refrigerant side integrated module and the liquid-cooled side integrated module, the integrated module 1 can achieve a compact structure and higher integration of the thermal management system 10000, which can better realize a platform-based design of the entire vehicle and facilitate the integrated layout and control of the entire vehicle.

[0039] According to some embodiments of the present disclosure, as shown in FIGS. 3 and 4 , the second flow path plate 20 is provided with a water tank interface connected to the internal liquid cooling flow path, and the integrated module 1 further includes a water refill tank 70, which is fixed to the second flow path plate 20 and connected to the water tank interface. In some embodiments, the water refill tank 70 is provided on the second flow path plate 20 and connected to the water tank interface of the second flow path plate 20, and the water tank interface is connected to the internal liquid cooling flow path, achieving a connection between the water refill tank 70 and the internal liquid cooling flow path of the second flow path plate 20 and improving the integration degree of the integrated module 1. In some embodiments, the water refill tank 70 is connected to the internal liquid cooling flow path to refill the internal liquid cooling flow path, thereby achieving liquid shortage protection for the liquid cooling side integrated module and ensuring the cooling effect of the internal liquid cooling flow path on the motor electronic control radiator 500. It can be understood that the minimum liquid level line of the water replenishment tank 70 must be higher than the height of the heat exchanger 30 so that the refrigerant in the water replenishment tank 70 can flow into the heat exchanger 30 and ensure heat exchange efficiency.

[0040] 2 , the heat exchanger 30 is located on the opposite side of the first flow path plate 10 from the second flow path plate 20, and the water make-up tank 70 is located on the opposite side of the second flow path plate 20 from the first flow path plate 10. In some embodiments, the second flow path plate 20 is fixed to the first flow path plate 10, the heat exchanger 30 is located on the side of the first flow path plate 10 facing away from the second flow path plate 20, and the water make-up tank 70 is located on the side of the second flow path plate 20 facing away from the first flow path plate 10. This optimizes the spatial layout of the integrated module 1, allowing the refrigerant-side and liquid-cooling-side integrated module interfaces to be located on both sides of the integrated module 1, preventing the two pipelines from interfering with each other, facilitating the pipeline layout of the entire vehicle, and making the overall vehicle layout more rational and aesthetically pleasing.

[0041] According to some embodiments of the present disclosure, as shown in FIGS. 3 and 4 , the second flow path plate 20 is provided with a water pump interface connected to the internal liquid cooling flow path, and the integrated module 1 further includes a water pump 60, which is fixed to the second flow path plate 20 and connected to the water pump interface. In some embodiments, the second flow path plate 20 has a water pump interface, and the water pump 60 is fixed to the second flow path plate 20 and connected to the water pump interface, which is convenient for arranging the water pump 60 and connecting it to the liquid cooling flow path. In some embodiments, the water pump 60 can drive and circulate the coolant in the internal liquid cooling flow path, and the internal liquid cooling flow path can be connected to the corresponding water pump interface to achieve connection with the water pump 60, thereby improving the integration degree of the integrated module 1.

[0042] According to some embodiments of the present disclosure, as shown in FIGS. 3 and 4 , the integrated module 1 further includes a switching valve 50. The switching valve 50 is disposed on the second flow path plate 20 and operates to allow or block the refrigerant from flowing through the second heat exchange flow path. In some embodiments, the refrigerant flowing through the second heat exchange flow path can exchange heat with the refrigerant in the first heat exchange flow path, thereby cooling the refrigerant. The switching valve 50 operates to selectively switch the thermal management system 10000 to an appropriate operating mode depending on heat dissipation requirements to meet differentiated actual needs. In some embodiments, the integrated module 1 further includes a refrigerant circuit. The refrigerant circuit is capable of heat exchange with a motor electronic control radiator 500. The motor electronic control radiator 500 can dissipate heat from the motor electronic control module of the vehicle 1000 to ensure that the motor electronic control module has a settable operating temperature. The second heat exchange flow path is configured as part of the refrigerant circuit. The refrigerant in the first heat exchange flow path can exchange heat with the refrigerant in the second heat exchange flow path, and as a result, the refrigerant in the first heat exchange flow path can indirectly cool the motor electronic control radiator 500 to ensure that the motor electronic control module has a settable operating temperature.

[0043] According to some embodiments of the present disclosure, the second flow path plate 20 includes a second water side interface 22, which is connected to the internal liquid cooling flow path, and which can be configured to connect to an external first radiator 400. In some embodiments, the second flow path plate 20 has a first water side interface 21 and a second water side interface 22, where the first water side interface 21 is connected to the motor electronic control radiator 500 so that the coolant can pass through the motor electronic control radiator 500 and exchange heat with the motor electronic control radiator 500, and the second water side interface 22 is connected to the first radiator 400 so that the coolant can flow out of the first radiator 400 and exchange heat with the heat exchanger 30.

[0044] According to some embodiments of the present disclosure, the switching valve 50 is a four-way valve, and the internal liquid cooling flow paths include a first flow path, a second flow path, a third flow path, a fourth flow path, and a fifth flow path. The first flow path is connected to the water pump interface and the third heat exchanger interface 23, the second flow path is connected to the first flow path and the first valve port 51 of the switching valve 50, respectively. The third flow path is connected to the fourth heat exchanger interface 24 and the second valve port 52 of the switching valve 50, respectively. The fourth flow path is connected to the third valve port 53 of the switching valve 50 and the first water-side interface 21, respectively. The fifth flow path is connected to the fourth valve port 54 of the switching valve 50 and the second water-side interface 22, respectively. In some embodiments, a first flow path of the internal liquid cooling flow path connects the water pump 60 with the heat exchanger 30, and the switching valve 50 has a first valve port 51, a second valve port 52, a third valve port 53, and a fourth valve port 54. The switching valve 50 can selectively control the conduction of the four valve ports to control the direction of coolant flow.

[0045] In some embodiments, the switching valve 50 controls the structure of the liquid cooling side integrated module to switch between multiple operating modes. In a first operating mode, the refrigerant can pass through the motor electronic control radiator 500 and the first radiator 400 to form a refrigerant circuit. At this time, the first radiator 400 uses the refrigerant to absorb heat from the motor electronic control radiator 500, thereby lowering the temperature of the motor electronic control radiator 500 and ensuring a cooling effect for the motor electronic control module. In a second operating mode, the refrigerant flows through the motor electronic control radiator 500 and the second heat exchange path to form a refrigerant circuit. At this time, the refrigerant flows through the second heat exchange path to exchange heat with the refrigerant in the first heat exchange path, recovering residual heat to lower the temperature of the refrigerant and also ensuring a cooling effect for the motor electronic control module. In a third operating mode, the refrigerant flows through the motor electronic control radiator 500, the second heat exchange path, and the first radiator 400 to form a refrigerant circuit. At this time, the first radiator 400 can use the refrigerant to remove heat from the motor electronic control radiator 500, while the refrigerant flows through the second heat exchange path and exchanges heat with the refrigerant in the first heat exchange path to lower the refrigerant's temperature, thereby achieving dual cooling of the motor electronic control radiator 500 and improving the cooling effect on the motor electronic control module. It can be understood that the first working mode can be a high-temperature heat dissipation mode, the second working mode can be a heat pump working mode below -10°C, and the third working mode can be a heat pump working mode between -10°C and 10°C. By setting the switching valve 50, the thermal management system 10000 can control the flow direction of the refrigerant according to the heat dissipation demand, so as to switch the thermal management system 10000 to an appropriate operating mode to meet actual differentiated needs.

[0046] According to some embodiments of the present disclosure, the first water side interface 21 and the second water side interface 22 extend in the same direction. In some embodiments, the second flow path plate 20 is provided with the first water side interface 21 and the second water side interface 22 extending in the same direction, so that the pipelines connected to the water side interfaces can be connected to the same side of the integrated module 1, which is convenient for the pipeline layout of the entire vehicle.

[0047] According to some embodiments of the present disclosure, the first water side interface 21 and the second water side interface 22 are located on the edge of the second flow path plate 20, on the side of the switching valve 50 that is far from the water pump 60. In some embodiments, the first water side interface 21 and the second water side interface 22 are located on the edge of the second flow path plate 20 to prevent the water side interface of the second flow path plate 20 from interfering with the arrangement of other pipelines when connected to a corresponding structure. On the other hand, to avoid the pipeline connected to the water pump 60, the first water side interface 21 and the second water side interface 22 are located on the side of the switching valve 50 that is far from the water pump 60, so that the pipeline connected to the water side interface can be connected to the edge of the integrated module 1, making the pipeline arrangement of the entire vehicle more rational and aesthetically pleasing.

[0048] According to some embodiments of the present disclosure, as shown in FIGS. 1-4 , the external device interface includes a gas-liquid separation inlet interface, and the integrated module 1 further includes a gas-liquid separator 40, the gas-liquid separator 40 being fixed to the first flow path plate 10, and an inlet end of the gas-liquid separator 40 being connected to the gas-liquid separation inlet interface. In some embodiments, the plurality of external device interfaces include a gas-liquid separation inlet interface, the gas-liquid separator 40 having an inlet end, the gas-liquid separator 40 being fixed to the first flow path plate 10, and an inlet end of the gas-liquid separator 40 being connected to the gas-liquid separation inlet interface, thereby positioning the gas-liquid separator 40 and enabling the gas-liquid separator 40 to communicate with the refrigerant flow paths in the first flow path plate 10. In the thermal management system 10000, the refrigerant can be converted between a gaseous state and a liquid state to absorb and release heat. When the gaseous refrigerant circulates through the refrigerant pipes in the thermal management system 10000, the liquid refrigerant is transported within the refrigerant pipes through heat exchange with other structures. The gas-liquid separator 40 is positioned to separate liquid refrigerant from gas refrigerant in the gas-liquid mixture. The gas-liquid separator 40 can receive gaseous refrigerant through its inlet end. The gas-liquid separator 40 separates liquid refrigerant from gaseous refrigerant in the gas-liquid mixture and removes any liquid droplets entrained in the gas. The structure connected to the gas-liquid separator 40 can be connected to a corresponding gas-liquid separator inlet interface to achieve connection with the gas-liquid separator 40, thereby improving the integration level of the integrated module 1 and helping to save layout space within the vehicle. In some embodiments, the gas-liquid separator 40 can be fixed to the first flow path plate 10 with screws. In other embodiments, the gas-liquid separator 40 has a separator joint located at its inlet end and communicating with the inlet end, which is connected to another flow path or pipeline via the separator joint.

[0049] According to some embodiments of the present disclosure, as shown in FIG. 1 , the gas-liquid separator 40 and the second flow path plate 20 are disposed on the same side of the first flow path plate 10. In some embodiments, the gas-liquid separator 40 is connected to the first flow path plate 10 via a gas-liquid separation inlet interface. In order to make the overall structure of the integrated module 1 more compact, the gas-liquid separator 40 and the second flow path plate 20 are disposed on the same side to fully utilize the space of the integrated module 1 and improve the integration degree of the integrated module 1.

[0050] According to some embodiments of the present disclosure, the external device interface includes at least one group of heat exchange plate interfaces 14, each group of heat exchange plate interfaces 14 connected to both ends of the same heat exchange plate 80, and the heat exchange plate 80 is configured to regulate the temperature of the battery module. In some embodiments, multiple external device interfaces include heat exchange plate interfaces 14, each group of heat exchange plate interfaces 14 connected to both ends of the heat exchange plate 80. Vehicle battery modules generate heat during operation and require cooling. The heat exchange plate 80 can cool the battery module by exchanging heat with the battery module when the temperature of the battery module becomes too high. A coolant circulates within the heat exchange plate 80 and exchanges heat with the battery module through contact with the heat exchange plate 80, thereby removing heat generated in the battery module through the circulation of the coolant. The heat exchange plate 80 is provided to improve the safety and durability of the battery module, accelerate the cooling rate of the battery module, and realize heat exchange during high-power charging.

[0051] According to some embodiments of the present disclosure, the openings of multiple external device interfaces are oriented in the same direction, so that pipelines connected to the external device interfaces can be connected to the same side of the integrated module 1, thereby facilitating pipeline layout throughout the vehicle.

[0052] According to some embodiments of the present disclosure, the openings of the first water side interface 21 and the second water side interface 22 are oriented in a first direction, and the openings of the multiple external device interfaces are oriented in a second direction, which are opposite to the first direction. In some embodiments, the first water side interface 21 and the second water side interface 22 on the second flow path plate 20 open in the first direction, and the multiple external device interfaces on the first flow path plate 10 open in the second direction. This allows the pipelines connected to the first water side interface 21, the second water side interface 22, and the multiple external device interfaces to be located on both sides of the integrated module 1, respectively, and the two pipelines do not interfere with each other, facilitating the pipeline layout of the entire vehicle and making the overall vehicle layout more rational and aesthetically pleasing.

[0053] According to some embodiments of the present disclosure, as shown in FIG. 1 , the heat exchanger 30 is positioned at the bottom corner of the first flow path plate 10 to facilitate pipeline layout of the heat exchanger 30, and the heat exchanger 30 is positioned at the edge of the first flow path plate 10 to avoid other structures positioned on the first flow path plate 10, thereby facilitating pipeline layout of the entire thermal management system 10000.

[0054] According to some embodiments of the present disclosure, mounting holes are provided on adjacent side walls of the first flow path plate 10, and the mounting holes can be configured to cooperate with the body of the vehicle 1000 to secure the integrated module 1. In some embodiments, the vehicle body is provided with mounting locations that cooperate with the mounting holes. The integrated module 1 is integrally secured to the vehicle body after the mounting holes cooperate with the mounting locations.

[0055] According to some embodiments of the present disclosure, the first flow path plate 10 is provided with a control valve group and a throttle valve group. The control valve group is configured to connect different refrigerant flow paths to form different refrigerant circuits, and the throttle valve group is configured to throttle and reduce the pressure of the refrigerant in the refrigerant circuits flowing therethrough. The control valve group has a first electrical connection port, and the throttle valve group has a second electrical connection port, and the opening directions of the first electrical connection port and the second electrical connection port are the same. In some embodiments, the openings of the first electrical connection port and the second electrical connection port are oriented in the same direction, so that connection of the first electrical connection port or the second electrical connection port can be achieved by the same operation, which reduces operational complexity and facilitates automated manufacturing. Meanwhile, such an arrangement allows the throttle valve group and the control valve group to have a more compact structure, allowing more throttle valves and control valves to be arranged in the same size space, or the same number of throttle valves and control valves to occupy a smaller space.

[0056] According to some embodiments of the present disclosure, the opening direction of the first electrical connection port is the same as the thickness direction of the first flow path plate 10.

Thus, when a connection between a component and the first electrical connection port is activated, the position of the component can be moved in a direction perpendicular to the surface of the first flow path plate 10 to prevent the control valves or the throttle valves on the surface of the first flow path plate 10 from affecting the connection between the component and the first electrical connection port, thereby facilitating quick and convenient connection of the component to the first electrical connection port or the second electrical connection port and realizing integrated setting of the control valves and the throttle valves.

[0059] In the battery cooling mode, the compressor 100 discharges a high-temperature, high-pressure gaseous refrigerant. The gaseous refrigerant flows into the external condenser 200, where it dissipates heat and liquefies. The medium-temperature, high-pressure liquid refrigerant flows sequentially through the first one-way valve 11a and the second one-way valve 11b to the first throttle valve 12a. The liquid refrigerant is throttled by the first throttle valve 12a, expands, flows out of the integrated module 1 through the heat exchanger plate interface 14, and then flows into the heat exchanger plate 80. At this time, the low-temperature, low-pressure gas-liquid mixture absorbs heat from the battery and evaporates, thereby cooling the battery module if the battery module temperature is too high. After heat exchange, the refrigerant passes through the heat exchanger plate interface 14 and re-enters the integrated module 1, flows through the first solenoid valve 13a, and then enters the gas-liquid separator 40. After gas-liquid separation, the refrigerant flows back into the compressor 100. This completes the battery cooling mode of the thermal management system 10000. Through the above process, the refrigerant circulates and cools the battery module.

[0060] In the battery heating mode, the compressor 100 discharges high-temperature, high-pressure gaseous refrigerant. The gaseous refrigerant that enters the integrated module 1 flows through the first electromagnetic valve 13a. The gaseous refrigerant then flows through the heat exchanger plate interface 14 into the heat exchanger plate 80. The gaseous refrigerant condenses and releases heat, heating the battery modules. This improves battery life and efficiency, improves battery capacity and vehicle driving range at low temperatures, and effectively shortens charging time. After heat exchange, the refrigerant enters the integrated module 1 through the heat exchanger plate interface 14 and is throttled by the first throttle valve 12a to expand.

The refrigerant dissipates heat in the on-board condenser 600, where the heat is mixed with air and blown into the vehicle interior by the fan, heating the interior. The refrigerant flowing out of the on-board condenser 600 flows into the integrated module 1, where it is throttled and expanded by the second throttle valve 12b. It then flows into the heat exchanger 30 via the first heat exchanger interface 15 for heat exchange. After heat exchange, the refrigerant passes through the second one-way valve 11b and enters the second solenoid valve 13b, and then into the gas-liquid separator 40. After gas-liquid separation, the refrigerant flows back into the compressor 100. This completes the air-conditioning / heating mode of the thermal management system 10000. The refrigerant circulates through the above process, providing heating and cooling for the interior of the vehicle.

[0069] In the battery cooling + air conditioning cooling + air conditioning heating mode, high-temperature, high-pressure gaseous refrigerant is discharged from the compressor 100 and divided into three parts. The first path enters the exterior condenser 200. The refrigerant dissipates heat in the exterior condenser 200 and is liquefied, becoming a medium-temperature, high-pressure liquid refrigerant. The liquid refrigerant flows from the first one-way valve 11a to the third throttle valve 12c for throttling and expansion.

This completes the battery cooling + air conditioning cooling + air conditioning heating mode of the thermal management system 10000.

[0070] The liquid-cooling integrated module can realize four operating modes. For example, in the high-temperature heat dissipation mode, the first valve port 51 and the third valve port 53 of the four-way valve are connected. The coolant in the first radiator 400 flows into the water pump 60 and then through the second flow path to the four-way valve. The four-way valve directs the coolant to the motor electronic control radiator 500. The coolant enters the motor electronic control radiator 500 for heat exchange and then returns to the first radiator 400, realizing the circulating operation in the high-temperature heat dissipation mode.

[0071] The liquid-cooled integrated module also has a heat pump operation mode below -10°C. At this time, the second valve port 52 and the fourth valve port 54 of the four-way valve are connected, and the refrigerant in the first radiator 400 flows into the water pump 60 and then into the heat exchanger 30 through the first flow path. After exchanging heat with the refrigerant in the heat exchanger 30, the refrigerant flows into the first radiator 400 through the third flow path to the four-way valve, realizing circulation operation in the heat pump operation mode below -10°C.

[0072] The liquid-cooled integrated module also has a heat pump operating mode between -10°C and 10°C. At this time, the second valve port 52 and the third valve port 53 of the four-way valve are connected, and the refrigerant in the first radiator 400 flows into the water pump 60 and then into the heat exchanger 30 through the first flow path. After exchanging heat with the refrigerant in the heat exchanger 30, the refrigerant flows into the motor electronic control radiator 500 for heat exchange and then returns to the first radiator 400, realizing the circulation operation of the heat pump operating mode between -10°C and 10°C.

[0073] The liquid-cooled integrated module also has a heat absorption / dissipation mode. The second valve port 52 of the four-way valve is connected to the third valve port 53 and the fourth valve port 54, respectively. The refrigerant in the first radiator 400 flows into the water pump 60 and then through the first flow path into the heat exchanger 30. After exchanging heat with the refrigerant in the heat exchanger 30, the refrigerant flows back to the four-way valve. The four-way valve guides the refrigerant to the motor electronically controlled radiator 500 and the first radiator 400, achieving circulation in the heat absorption / dissipation mode.

[0074] The integrated module 1 of the present disclosure divides the structures on the integrated module 1 into a refrigerant side and a liquid-cooled side by connecting the first flow path plate 10 and the second flow path plate 20. The refrigerant side integrated module includes structures such as a heat exchanger 30 and a gas-liquid separator 40, while the liquid-cooled side integrated module includes structures such as a switching valve 50, a water pump 60, and a water replenishment tank 70. The gas-liquid separator 40 is located on the same side as the liquid-cooled side integrated module, so the interfaces of the refrigerant side integrated module and the liquid-cooled side integrated module are located on both sides of the integrated module. This prevents interference between the two pipelines, facilitating the overall vehicle pipeline layout and resulting in a more rational and aesthetically pleasing overall vehicle layout. In this way, the thermal management system 10000 has a compact structure and a higher degree of integration, better realizing a platform-based design for the entire vehicle. The integrated module 1 as a whole forms a square structure, which can be configured for small vehicles.

[0075] A brief description of the thermal management system 10000 according to the present disclosure follows.

[0076] 5, the thermal management system 10000 according to the present disclosure includes the integrated module 1 described in any one of the above embodiments. Because the thermal management system 10000 according to the present disclosure includes the integrated module 1 of the above embodiments, the thermal management system 10000 has a compact structure and a higher degree of integration.

[0077] The vehicle 1000 of the present disclosure will be briefly described below.

[0078] 6, in the above embodiment, the vehicle 1000 according to the present disclosure includes a thermal management system 10000. In the above embodiment, since the vehicle 1000 according to the present disclosure is provided with the thermal management system 10000, the internal structure of the vehicle 1000 is compact and the wiring layout is more aesthetically pleasing.

[0079] In summary, the integrated module 1 of the present disclosure integrates the heat exchanger 30, gas-liquid separator 40, water pump 60, water replenishment tank 70, and switching valve 50 by connecting and integrating the first and second flow path plates 10 and 20. Furthermore, the first and second flow path plates 10 and 20, each with their own internal flow paths and inlet and outlet interfaces, simplify the pipeline connections in the thermal management system 10000, reduce the overall layout space of the thermal management system 10000, and facilitate the integrated layout and control of the entire vehicle. By connecting the first and second flow path plates 10 and 20, the refrigerant-side integrated module and the liquid-cooling-side integrated module are distributed on both sides, and the interfaces between the refrigerant-side integrated module and the liquid-cooling-side integrated module are located on both sides of the integrated module 1. This prevents the two pipelines from interfering with each other, facilitating the pipeline layout of the entire vehicle and making the overall vehicle layout more rational and aesthetically pleasing.
