[0046] In related technologies, the valve control components in conventional vehicle thermal management systems have poor structural flexibility and low concentration. Furthermore, the large number of integrated parts in valve control components makes vehicle assembly difficult.

[0047] The following is for reference. Figures 1-6 The integrated module 1 according to an embodiment of the present invention is described.

[0048] like Figure 1As shown, the integrated module 1 according to the present invention is used in the thermal management system of a vehicle. The integrated module 1 includes: a first valve seat 10, a second valve seat 20, and a heat exchanger 30. The first valve seat 10 has multiple refrigerant flow paths, a first heat exchanger interface 15, a second heat exchanger interface 16, multiple external device interfaces, a control valve group, and a throttling valve group. The first heat exchanger interface 15, the second heat exchanger interface 16, and the external device interfaces are respectively connected to corresponding refrigerant flow paths. Each external device interface is adapted to connect to a component in the vehicle's thermal management system. The control valve group is used to connect different refrigerant flow paths to form different refrigerant circuits. The throttling valve group is used to throttle and reduce the pressure of the refrigerant flowing through it in the refrigerant circuit. The second valve seat 20 is fixed to the first valve seat 10. The second valve seat 20 has an internal liquid cooling flow path and a third heat exchanger interface 23. The heat exchanger's fourth interface 24 and first water-side interface 21, the heat exchanger's third interface 23, fourth interface 24 and first water-side interface 21 are respectively connected to the corresponding internal liquid cooling flow path. The first water-side interface 21 is adapted to be connected to the external motor control radiator 500. The heat exchanger 30 is fixed to the first valve seat 10 and / or the second valve seat 20. The heat exchanger 30 is provided with a first heat exchange flow path and a second heat exchange flow path that exchange heat with each other. The two ends of the first heat exchange flow path are respectively connected to the heat exchanger's first interface 15 and second interface 16. The two ends of the second heat exchange flow path are respectively connected to the heat exchanger's third interface 23 and fourth interface 24. The openings of the first water-side interface 21 and multiple external device interfaces face the same direction.

[0049] Specifically, the integrated module 1 can be applied to the vehicle's thermal management system. The integrated module 1 integrates and arranges the control components of the thermal management system, and by increasing the integration level of the integrated module 1, it can save more space occupied by the thermal management system within the vehicle. The integrated module 1 includes a first valve seat 10 and a second valve seat 20. The first valve seat 10 has multiple refrigerant flow paths, and the second valve seat 20 has an internal liquid cooling flow path. The first valve seat 10 has multiple external device interfaces and is connected to various components in the vehicle's thermal management system through these interfaces. The second valve seat 20 is fixed to the first valve seat 10 and has a first water-side interface 21. The first water-side interface 21 of the second valve seat 20 faces the same direction as the multiple external device interfaces of the first valve seat 10 to facilitate the overall piping layout of the vehicle. The heat exchanger 30 is provided with a first heat exchange flow path and a second heat exchange flow path that can exchange heat with each other. The first port 15 and the second port 16 of the heat exchanger on the first valve seat 10, which are connected to the refrigerant flow path, are respectively connected to the two ends of the first heat exchange flow path. The third port 23 and the fourth port 24 of the heat exchanger on the second valve seat 20, which are connected to the internal liquid cooling flow path, are respectively connected to the two ends of the second heat exchange flow path. The heat exchanger 30 can realize heat exchange between the refrigerant flow path and the internal liquid cooling flow path.

[0050] More specifically, the control valve assembly located on the first valve seat 10 can connect different refrigerant flow paths within the first valve seat 10, thereby forming different refrigerant circuits in the refrigerant-side integrated module, allowing the refrigerant to flow through each structure of the refrigerant-side integrated module. The throttling valve assembly located on the first valve seat 10 can throttle and reduce the pressure of the refrigerant in each refrigerant circuit, thereby ensuring refrigerant circulation in the refrigerant-side integrated module. In some embodiments, the refrigerant can flow through the refrigerant flow path in the first valve seat 10 to each refrigerant circuit of the thermal management system. The first valve seat 10 is connected to the structure through which the refrigerant flows and together with the structure through which the refrigerant flows constitutes the refrigerant-side integrated module. The second valve seat 20 is connected to the structure through which the coolant flows and together with the structure through which the coolant flows constitutes the liquid-cooled integrated module.

[0051] According to the present invention, the integrated module 1 divides the various structures located on the integrated module 1 into a refrigerant side and a liquid cooling side by setting a first valve seat 10 and a second valve seat 20 connected to each other. The integrated module 1 integrates the refrigerant side integrated module and the liquid cooling side integrated module, making the thermal management system structure compact and more integrated, which is conducive to the platform design of the whole vehicle. At the same time, the refrigerant side integrated module and the liquid cooling side integrated module exchange heat through the heat exchanger 30, and the heat exchanger 30 is set on the refrigerant side and / or the liquid cooling side, which can reduce the overall layout space of the integrated module 1 and facilitate the integrated layout and control of the whole vehicle.

[0052] According to some embodiments of the present invention, such as Figures 4-5 As shown, the heat exchanger 30 is fixed to the first valve seat 10, and external device interfaces are provided on both the left and right sides of the heat exchanger 30. Specifically, in some embodiments, the heat exchanger 30 is fixed to the first valve seat 10 and arranged among multiple external device interfaces of the first valve seat 10. This facilitates the arrangement of the heat exchanger 30 while improving the integration level of the integrated module 1, which helps save interior space and facilitates platform-based layout.

[0053] According to some embodiments of the present invention, the control valve group includes multiple control valves, and a portion of control valves are provided on both the left and right sides of the heat exchanger 30. Specifically, the operation of the control valve group can switch the refrigerant flow direction in the first valve seat 10. The control valve group includes multiple control valves. In some embodiments, the heat exchanger 30 is fixed to the first valve seat 10 and arranged between the multiple control valves of the first valve seat 10. This facilitates the arrangement of the heat exchanger 30 while improving the integration level of the integrated module 1. Furthermore, the multiple control valves can connect different refrigerant flow paths in different air conditioning modes, thereby realizing multi-mode switching of the thermal management system.

[0054] According to some embodiments of the present invention, such as Figures 1-3As shown, the external device interface includes a gas-liquid separation inlet interface; the integrated module 1 also includes a gas-liquid separator 40, which is fixed to the first valve seat 10, and the inlet end of the gas-liquid separator 40 is connected to the gas-liquid separation inlet interface. Specifically, multiple external device interfaces include a gas-liquid separation inlet interface, the gas-liquid separator 40 has an inlet end, the gas-liquid separator 40 is fixed to the first valve seat 10, and the inlet end of the gas-liquid separator 40 is connected to the gas-liquid separation inlet interface to facilitate the arrangement of the gas-liquid separator 40 and to enable communication between the gas-liquid separator 40 and the refrigerant flow path inside the first valve seat 10. In the thermal management system, the refrigerant can transform between a gaseous and a liquid state to absorb and release heat. When the gaseous refrigerant flows through the refrigerant pipeline in the thermal management system, it exchanges heat with other structures, carrying the liquid refrigerant along with it. A gas-liquid separator 40 is installed to separate the liquid and gaseous refrigerant in the gas-liquid mixture. The gaseous refrigerant enters the gas-liquid separator 40 through its inlet. The gas-liquid separator 40 separates the liquid and gaseous refrigerant in the gas-liquid mixture, removing any liquid droplets entrained in the gas. Structures connected to the gas-liquid separator 40 can be connected to corresponding gas-liquid separation inlet interfaces to achieve connection with the gas-liquid separator 40, improving the integration level of the integrated module 1 and saving interior space. In some embodiments, the gas-liquid separator 40 can be fixed to the first valve seat 10 with screws. In other embodiments, the gas-liquid separator 40 has a separator connector located at and connected to the inlet end, and the inlet end is connected to other flow channels or pipelines through the separator connector.

[0055] According to some embodiments of the present invention, such as Figures 1-3 As shown, the gas-liquid separator 40 and the second valve seat 20 are located on the same side of the first valve seat 10. Specifically, the gas-liquid separator 40 is connected to the first valve seat 10 through the gas-liquid separation inlet interface in the external device interface. In order to make the overall structure of the integrated module 1 more compact, the gas-liquid separator 40 and the second valve seat 20 are set on the same side to make full use of the space of the integrated module 1 and improve the integration level of the integrated module 1.

[0056] According to some embodiments of the present invention, the external device interface includes at least one set of heat exchange plate interfaces 14, each set of heat exchange plate interfaces 14 being connected to both ends of the same heat exchange plate 80, which is used to regulate the temperature of the battery module. Specifically, multiple external device interfaces include heat exchange plate interfaces 14, each set of heat exchange plate interfaces 14 being connected to both ends of the heat exchange plate 80. When the vehicle battery module is working, it generates heat and needs to be cooled. When the battery module temperature is too high, the heat exchange plate 80 can exchange heat with the battery module to cool it down. The coolant circulates in the heat exchange plate 80 and exchanges heat with the battery module through contact with the heat exchange plate 80, thereby removing the heat generated by the battery module through coolant circulation. Setting up the heat exchange plate 80 can improve the safety and durability of the battery module, accelerate the cooling rate of the battery module, and realize heat exchange under high-power charging.

[0057] According to some embodiments of the present invention, such as Figures 1-3 As shown, the integrated module 1 also includes a switching valve 50. The switching valve 50 is located on the second valve seat 20. The switching valve 50 actuates to allow coolant to flow into the second heat exchange path or to prevent coolant from flowing into the second heat exchange path. Specifically, after flowing into the second heat exchange path, the coolant can exchange heat with the refrigerant in the first heat exchange path, so that the refrigerant cools the coolant. The switching valve 50 actuates to selectively switch the thermal management system to a suitable operating mode according to heat dissipation requirements to meet actual differentiated needs. In some embodiments, the integrated module 1 also has a coolant circuit adapted to exchange heat with the motor control radiator 500. The motor control radiator 500 can dissipate heat from the vehicle's motor control module to ensure that the motor control module has a suitable operating temperature. The second heat exchange path is constructed as part of the coolant circuit. The refrigerant in the first heat exchange path can exchange heat with the coolant in the second heat exchange path, so that the refrigerant in the first heat exchange path can indirectly cool the motor control radiator 500, further ensuring that the motor control module has a suitable operating temperature.

[0058] According to some embodiments of the present invention, such as Figures 1-3 As shown, the second valve seat 20 is provided with a water pump interface connected to the internal liquid cooling flow path. The integrated module 1 also includes a water pump 60, which is fixed to the second valve seat 20 and connected to the water pump interface. Specifically, the second valve seat 20 has a water pump interface, and the water pump 60 is fixed to the second valve seat 20 and connected to the water pump interface, which facilitates the arrangement of the water pump 60 and enables the water pump 60 to communicate with the liquid cooling flow path. In some embodiments, the water pump 60 can drive the coolant in the coolant circuit to circulate, and the coolant circuit can be connected to the corresponding water pump interface to achieve connection with the water pump 60, which can improve the integration level of the integrated module 1.

[0059] According to some embodiments of the present invention, the second valve seat 20 further includes a second water-side interface 22 connected to an internal liquid cooling flow path. The second water-side interface 22 is adapted to be connected to an external first radiator 400. The openings of the second water-side interface 22 and a plurality of external device interfaces face the same direction. Specifically, the second valve seat 20 has a first water-side interface 21 and a second water-side interface 22. The first water-side interface 21 is connected to the motor control radiator 500 so that coolant can pass through and exchange heat with the motor control radiator 500. The second water-side interface 22 is connected to the first radiator 400 so that coolant flows out from the first radiator 400 and exchanges heat with the heat exchanger 30.

[0060] According to some embodiments of the present invention, such as Figure 6 As shown, the switching valve 50 is a four-way valve, and its internal liquid cooling flow path includes a first flow channel, a second flow channel, a third flow channel, a fourth flow channel, and a fifth flow channel. The first flow channel is connected to the water pump interface and the third interface 23 of the heat exchanger; the second flow channel is connected to the first flow channel and the first valve port 51 of the switching valve 50; the third flow channel is connected to the fourth interface 24 of the heat exchanger and the second valve port 52 of the switching valve 50; the fourth flow channel is connected to the third valve port 53 of the switching valve 50 and the first water-side interface 21; and the fifth flow channel is connected to the fourth valve port 54 of the switching valve 50 and the second water-side interface 22. Specifically, the first flow channel of the internal liquid cooling flow path connects the water pump 60 and the heat exchanger 30. 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 opening of the four valve ports to control the flow direction of the coolant.

[0061] In some embodiments, the switching valve 50 actuates to control the switching between multiple operating modes of the various structures of the liquid-cooled integrated module. In the first operating mode, coolant flows through the motor control radiator 500 and the first radiator 400 to form a coolant circuit. In this mode, the first radiator 400 can remove heat from the motor control radiator 500 through the coolant, thereby reducing the temperature of the motor control radiator 500 and ensuring a cooling effect on the motor control module. In the second operating mode, coolant flows through the motor control radiator 500 and the second heat exchange path to form a coolant circuit. In this mode, the coolant flows through the second heat exchange path to exchange heat with the refrigerant in the first heat exchange path, and the refrigerant is recovered from the coolant. Waste heat is used to lower the coolant temperature, thus ensuring effective cooling of the motor control module. In the third operating mode, the coolant flows through the motor control radiator 500, the second heat exchange path, and the first radiator 400 to form a coolant circuit. At this time, the first radiator 400 can remove heat from the motor control radiator 500 through the coolant. Simultaneously, the coolant flows through the second heat exchange path to exchange heat with the refrigerant in the first heat exchange path, thereby lowering the coolant temperature and achieving dual cooling of the motor control radiator 500, improving the cooling effect on the motor control module. It can be understood that the first operating mode can be a high-temperature cooling mode, the second operating mode can be a heat pump operating mode below -10℃, and the third operating mode can be a heat pump operating mode between -10℃ and 10℃. By setting the switching valve 50, the thermal management system can control the coolant flow direction according to the heat dissipation requirements, thereby switching the thermal management system to the appropriate operating mode to meet actual differentiated needs.

[0062] According to some embodiments of the present invention, a portion of the valve seat of the switching valve 50 extends beyond the first valve seat 10 to form an extension, and the first water-side interface 21 and the second water-side interface 22 are located in the extension. Specifically, in order to make the first water-side interface 21 and the second water-side interface 22 of the second valve seat 20 face the same direction as the plurality of external device interfaces of the first valve seat 10, an extension is provided in the second valve seat 20 and the first water-side interface 21 and the second water-side interface 22 are provided in the extension. The extension is formed at the edge of the second valve seat 20, and placing the first water-side interface 21 and the second water-side interface 22 at the edge of the second valve seat 20 facilitates the arrangement of pipelines. In some embodiments, the switching valve 50 is provided at the edge of the second valve seat 20 and has an extension that extends beyond the first valve seat 10 to facilitate the arrangement of pipelines. In some embodiments, the plurality of external device interfaces are open toward the extension direction of the first valve seat 10, and the second valve seat 20 is also provided with the first water-side interface 21 and the second water-side interface 22 that are open toward the extension direction of the extension, so that pipelines can be connected to the same side of the integrated module 1, which facilitates the pipeline arrangement of the whole vehicle.

[0063] According to some embodiments of the present invention, such as Figures 2-3As shown, the second valve seat 20 is provided with a water tank interface connected to the internal liquid cooling flow path. The integrated module 1 also includes a water replenishment tank 70, which is fixed to the second valve seat 20 and connected to the water tank interface. Specifically, the water replenishment tank 70 is located on the second valve seat 20 and connected to the water tank interface of the second valve seat 20, and the water tank interface is connected to the internal liquid cooling flow path, realizing the communication between the water replenishment tank 70 and the internal liquid cooling flow path of the second valve seat 20, while improving the integration level of the integrated module 1. In some embodiments, the water replenishment tank 70 is connected to the coolant circuit to replenish the coolant circuit, so as to realize the liquid shortage protection of the liquid-cooled integrated module and ensure the cooling effect of the internal liquid cooling flow path on the motor control radiator 500. It is understood that the lowest liquid level line of the water replenishment tank 70 should be higher than the height of the heat exchanger 30 so that the coolant in the water replenishment tank 70 can flow into the heat exchanger 30 to ensure heat exchange efficiency.

[0064] According to some embodiments of the present invention, such as Figure 1 As shown, the water tank 70 is located above the switching valve 50 and the water pump 60. Specifically, the water tank 70 is located above the switching valve 50 and the water pump 60 to utilize gravity to deliver coolant to the pipeline connected to the switching valve 50 or the water pump 60.

[0065] According to some embodiments of the present invention, the first valve seat 10 is provided with a control valve assembly and a throttling valve assembly. The control valve assembly is used to connect different refrigerant flow paths to form different refrigerant circuits. The throttling valve assembly is used to throttle and reduce the pressure of the refrigerant in the refrigerant circuit flowing through it. The control valve assembly has a first electrical connection port 17, and the throttling valve assembly has a second electrical connection port 18. The openings of the first electrical connection port 17 and the second electrical connection port 18 face the same direction. Specifically, by making the openings of the first electrical connection port 17 and the second electrical connection port 18 face the same direction, the connection of the first electrical connection port 17 or the second electrical connection port 18 can be achieved through the same operation, which facilitates the reduction of operational complexity and the realization of automated production. At the same time, this arrangement allows the structure of the throttling valve assembly and the control valve assembly to be more compact, so that more throttling valves and control valves can be installed in the same space, or the same number of throttling valves and control valves occupy less space.

[0066] According to some embodiments of the present invention, the opening of the first electrical connection port 17 is oriented in the same direction as the thickness of the first valve seat 10. Specifically, in order to make full use of the space of the first valve seat 10 and avoid the first electrical connection port 17 occupying too much space, the control valve assembly and the throttle valve assembly are arranged along the length and / or width direction of the first valve seat 10, and the opening of the first electrical connection port 17 is oriented perpendicular to the surface of the first valve seat 10. When connecting the operating component to the first electrical connection port 17, it is only necessary to move the position of the component in a direction perpendicular to the surface of the first valve seat 10, so as to avoid the control valve assembly or throttle valve assembly on the surface of the first valve seat 10 affecting the connection between the component and the first electrical connection port 17. This facilitates the quick and convenient connection of the component to the first electrical connection port 17 or the second electrical connection port 18, realizing the integrated setting of the control valve and the throttle valve.

[0068] like Figure 6As shown, the thermal management system also includes a compressor 100, an in-vehicle condenser 600, an in-vehicle evaporator 700, an external condenser 200, a refrigerant reservoir 300, a heat exchange plate 80, a motor-controlled radiator 500, and a first radiator 400. The compressor 100, in-vehicle condenser 600, in-vehicle evaporator 700, external condenser 200, refrigerant reservoir 300, and heat exchange plate 80 are connected to the refrigerant side of the integrated module 1, while the motor-controlled radiator 500 and first radiator 400 are connected to the liquid-cooled side of the integrated module 1. The refrigerant in the refrigerant circuit can be converted between gaseous and liquid states under the action of the compressor 100. The thermal management system has multiple modes, such as battery cooling mode, battery heating mode, air conditioning cooling mode, air conditioning heating mode, battery cooling + air conditioning cooling mode, battery heating + air conditioning cooling mode, battery cooling + air conditioning heating mode, battery heating + air conditioning heating mode, air conditioning cooling + air conditioning heating mode, battery heating + air conditioning cooling + air conditioning heating mode, battery cooling + air conditioning cooling + air conditioning heating mode, and so on.

[0069] In the battery cooling mode, the compressor 100 discharges high-temperature, high-pressure gaseous refrigerant. This gaseous refrigerant enters the external condenser 200 and liquefies upon releasing heat. 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. Within the first throttle valve 12a, the liquid refrigerant expands and flows out of the integrated module 1 through the heat exchanger interface 14, entering the heat exchanger 80. At this point, the low-temperature, low-pressure gas-liquid mixture absorbs heat from the battery and evaporates, thus cooling the battery module when its temperature is too high. After heat exchange, the refrigerant again enters the integrated module 1 through the heat exchanger interface 14, flows through the first solenoid valve 13a, and then enters the gas-liquid separator 40. After gas-liquid separation, the refrigerant re-enters the compressor 100. This is the battery cooling mode of the thermal management system. The refrigerant circulates through this process to cool the battery module.

[0070] In the battery heating mode, the compressor 100 discharges high-temperature, high-pressure gaseous refrigerant. This gaseous refrigerant flows into the integrated module 1 and then to the first solenoid valve 13a. It then flows into the heat exchange plate 80 through the heat exchange plate interface 14. At this point, the gaseous refrigerant condenses and releases heat, heating the battery module, thereby improving battery life and efficiency. It also increases battery capacity and vehicle range at low temperatures and effectively shortens charging time. After heat exchange, the refrigerant enters the integrated module 1 through the heat exchange plate interface 14 and expands through the first throttling valve 12a. The liquid refrigerant flows through the third one-way valve 11c to the first heat exchanger interface 15 and enters the heat exchanger 30 to absorb heat and evaporate. The refrigerant flowing out of the heat exchanger 30 through the second heat exchanger interface 16 flows through the second solenoid valve 13b to the gas-liquid separator 40. After gas-liquid separation, the refrigerant re-enters the compressor 100. This is the battery heating mode of the thermal management system. The refrigerant circulates through this process to heat the battery module.

[0071] In the air conditioning cooling mode, compressor 100 discharges high-temperature, high-pressure gaseous refrigerant. This gaseous refrigerant enters the external condenser 200, where it releases heat and liquefies into a medium-temperature, high-pressure liquid refrigerant. The liquid refrigerant flows through the first one-way valve 11a to the third throttling valve 12c, where it expands. The low-temperature, low-pressure gas-liquid mixture enters the internal evaporator 700, absorbing heat and evaporating. This absorption of heat from the vehicle's interior environment lowers the interior temperature. The low-temperature, low-pressure gaseous refrigerant then re-enters the integrated module 1 and enters the gas-liquid separator 40. After gas-liquid separation, the refrigerant re-enters compressor 100. This is the air conditioning cooling mode of the thermal management system. The refrigerant's cyclical operation, following this process, effectively cools the passenger compartment.

[0072] In the air conditioning heating mode, compressor 100 discharges high-temperature, high-pressure gaseous refrigerant. This gaseous refrigerant enters the vehicle's condenser 600, where it releases heat. This heat mixes with air and is blown into the vehicle interior by a blower, heating the passenger compartment. The refrigerant flowing out of the condenser 600 enters integrated module 1 and expands under throttling by the second expansion valve 12b. It then passes through the first interface 15 of the heat exchanger and enters heat exchanger 30 for heat exchange. After heat exchange, the refrigerant passes through the second one-way valve 11b and then the second solenoid valve 13b before entering the gas-liquid separator 40. The separated refrigerant then re-enters compressor 100. This is the air conditioning heating mode of the thermal management system. The refrigerant circulates through this process to achieve heating for the passenger compartment.

[0073] In the battery cooling + air conditioning cooling mode, the compressor 100 discharges high-temperature, high-pressure gaseous refrigerant. The gaseous refrigerant is split into two paths. One path enters the external condenser 200, where it releases 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 expands and throttles within the first throttle valve 12a, then flows out of the integrated module 1 through the heat exchanger interface 14 and into the heat exchanger 80. At this point, the low-temperature, low-pressure gas-liquid mixture absorbs heat from the battery and evaporates. The refrigerant after heat exchange then flows back into the integrated module 1 through the heat exchanger interface 14, flowing through the first... After solenoid valve 13a, the refrigerant enters the gas-liquid separator 40; another path leads to the external condenser 200. In the external condenser 200, the gaseous refrigerant releases heat and liquefies, becoming a medium-temperature, high-pressure liquid refrigerant. This liquid refrigerant flows through the first one-way valve 11a to the third throttling valve 12c for expansion. The low-temperature, low-pressure gas-liquid mixture enters the internal evaporator 700, absorbing heat and evaporating. The refrigerant absorbs heat from the vehicle's interior, causing the interior temperature to drop. The low-temperature, low-pressure gaseous refrigerant then re-enters the integrated module 1 and enters the gas-liquid separator 40. Both refrigerant paths undergo gas-liquid separation within the gas-liquid separator 40. The separated refrigerant then re-enters the compressor 100.
