[0037] In some embodiments, the integrated module 1 can be applied to the thermal management system 10000 of a vehicle 1000. The integrated module 1 integrates and arranges the control components of the thermal management system 10000. By increasing the level of integration of the integrated module 1, the space occupied by the thermal management system 10000 in the vehicle can be saved more significantly. 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, and the second flow path plate 20 has internal liquid cooling flow paths. The first flow path plate 10 has multiple external device interfaces, which connect to various components of the vehicle thermal management system 10000. 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 a motor-electronically controlled radiator 500 so that the refrigerant can pass through the motor-electronically controlled radiator 500 and exchange heat with the motor-electronically controlled radiator 500. The heat exchanger 30 is provided with a first heat exchange channel and a second heat exchange channel that exchange heat with each other. The first heat exchange channel is connected to a first heat exchanger interface 15 and a second heat exchanger interface 16 on a first channel plate 10 connected to a refrigerant channel, respectively, and the second heat exchange channel is connected to a third heat exchanger interface 23 and a fourth heat exchanger interface 24 on a second channel plate 20 connected to an internal liquid cooling channel, respectively, and the second heat exchange channel is connected to a third heat exchanger interface 23 and a fourth heat exchanger interface 24 on a second channel plate 20 connected to an internal liquid cooling channel, respectively. The heat exchanger 30 can achieve heat exchange between the refrigerant channel and the internal liquid cooling channel. In some embodiments, the refrigerant can flow through each refrigerant circuit of the thermal management system 10000 through the refrigerant channel in the first channel plate 10. The first channel plate 10 is connected to a structure through which the refrigerant flows and together with the structure constitutes a refrigerant-side integrated module. The second channel plate 20 is connected to a structure through which the refrigerant flows and together with these structures constitutes a liquid-cooled-side integrated module.

[0038] According to the integrated module 1 of this disclosure, the structure located on the integrated module 1 is divided into a refrigerant side and a liquid-cooled side by connecting the first flow path plate 10 and the second flow path plate 20. On the other hand, since the refrigerant side integrated module and the liquid-cooled side integrated module exchange heat via a 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 thermal management system 10000 can be made into a compact structure and more highly integrated, enabling a better platform-based design for the entire vehicle and facilitating the integrated layout and control of the entire vehicle.

[0039] According to some embodiments of the present disclosure, as shown in Figures 3-4, the second flow path plate 20 is provided with a water tank interface connected to an internal liquid cooling flow path, and the integrated module 1 further includes a water replenishment tank 70, which is fixed to the second flow path plate 20 and connected to the water tank interface. In some embodiments, the water replenishment 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, the water tank interface is connected to the internal liquid cooling flow path, achieving a connection between the water replenishment tank 70 and the internal liquid cooling flow path of the second flow path plate 20 and improving the integration of the integrated module 1. In some embodiments, the water replenishment tank 70 is connected to the internal liquid cooling flow path to replenish 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 electronically controlled 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] In some embodiments of this disclosure, as shown in Figure 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 replenishment 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 positioned on the side of the first flow path plate 10 facing away from the second flow path plate 20, and the water replenishment tank 70 is positioned on the side of the second flow path plate 20 facing away from the first flow path plate 10, optimizing the spatial arrangement of the integrated module 1. As a result, the interfaces of the integrated module on the refrigerant side and the integrated module on the liquid cooling side can be positioned on both sides of the integrated module 1, the two pipelines do not interfere with each other, the pipeline arrangement of the entire vehicle becomes easier, and the overall layout of the vehicle becomes more rational and aesthetically pleasing.

[0041] In some embodiments of the present disclosure, as shown in Figures 3-4, the second flow path plate 20 is provided with a water pump interface connected to an 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 positioning the water pump 60 and enabling connection of the water pump 60 to the liquid cooling flow path. In some embodiments, the water pump 60 can drive and circulate the refrigerant 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, improving the integration of the integrated module 1.

[0042] According to some embodiments of the present disclosure, as shown in Figures 3-4, the integrated module 1 further includes a switching valve 50. The switching valve 50 is located on the second flow path plate 20 and operates to allow the refrigerant to flow into the second heat exchange flow path or to prevent the refrigerant from flowing into the second heat exchange flow path. In some embodiments, the refrigerant flowing into 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 according to the heat dissipation requirements in order to meet actual differentiated needs. In some embodiments, the integrated module 1 further includes a refrigerant circuit. The refrigerant circuit is heat exchangeable 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 configurable operating temperature. The second heat exchange flow path is configured as part of the refrigerant circuit. The refrigerant in the first heat exchange channel can exchange heat with the refrigerant in the second heat exchange channel, and as a result, the refrigerant in the first heat exchange channel can indirectly cool the motor electronic control radiator 500, ensuring that the motor electronic control module has a configurable operating temperature.

[0043] According to some embodiments of the present disclosure, the second flow path plate 20 includes a second water-side interface 22, the second water-side interface 22 is connected to an internal liquid cooling flow path, and the second water-side interface 22 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, the first water-side interface 21 is connected to a motor-electronically controlled radiator 500 so that a refrigerant can pass through the motor-electronically controlled radiator 500 and exchange heat with the motor-electronically controlled radiator 500, and the second water-side interface 22 is connected to the first radiator 400 so that a refrigerant can flow out of the first radiator 400 and exchange heat with a heat exchanger 30.

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

[0045] In some embodiments, the switching valve 50 operates to control the structure of the liquid cooling side integrated module to switch between multiple operating modes. In the first operating mode, the refrigerant can form a refrigerant circuit through the motor electronic control radiator 500 and the first radiator 400. At this time, the first radiator 400 can lower the temperature of the motor electronic control radiator 500 by removing heat from the motor electronic control radiator 500 with the refrigerant, thereby ensuring a cooling effect on the motor electronic control module. In the second operating mode, the refrigerant flows through the motor electronic control radiator 500 and the second heat exchange channel to form a refrigerant circuit. At this time, the refrigerant flows through the second heat exchange channel and exchanges heat with the refrigerant in the first heat exchange channel, and the refrigerant can recover residual heat to lower the temperature of the refrigerant, thereby ensuring a cooling effect on the motor electronic control module. In the third operating mode, the refrigerant flows through the motor electronic control radiator 500, the second heat exchange channel, and the first radiator 400 to form a refrigerant circuit. At this time, the first radiator 400 can remove heat from the motor electronic control radiator 500 by the refrigerant, while the refrigerant flows through the second heat exchange channel and exchanges heat with the refrigerant in the first heat exchange channel, lowering the temperature of the refrigerant, resulting in 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 operating mode can be a high-temperature heat dissipation mode, the second operating mode can be a heat pump operating mode below -10°C, and the third operating mode can be a heat pump operating mode between -10°C and 10°C. By setting the switching valve 50, the thermal management system 10000 can control the direction of refrigerant flow according to the heat dissipation demand so that the thermal management system 10000 switches to an appropriate operating mode that meets the 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 pipelines connected to the water-side interfaces can be connected to the same side of the integrated module 1, which is advantageous for the pipeline layout of the entire vehicle.

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

[0048] According to some embodiments of this disclosure, as shown in Figures 1 to 4, the external device interface includes a gas-liquid separation inlet interface, and the integrated module 1 further includes a gas-liquid separator 40, which is fixed to a first flow path plate 10, and the inlet end of the gas-liquid separator 40 is connected to the gas-liquid separation inlet interface.

The thermal management system 10000 can achieve heat absorption and heat dissipation by converting the refrigerant between a gaseous state and a liquid state. When gaseous refrigerant circulates in the refrigerant pipeline within the thermal management system 10000, liquid refrigerant is transported in the refrigerant pipeline through heat exchange with other structures. The gas-liquid separator 40 is positioned to separate the liquid refrigerant from the gaseous refrigerant in the gas-liquid mixture of the refrigerant. The gaseous refrigerant can be introduced into the gas-liquid separator 40 from its inlet end. The gas-liquid separator 40 separates the liquid refrigerant from the gaseous refrigerant in the gas-liquid mixture of the refrigerant and removes any accompanying droplets in the gas. Structures connected to the gas-liquid separator 40 can be connected to a corresponding gas-liquid separation 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 in the vehicle. In some embodiments, the gas-liquid separator 40 can be fixed to the first flow path plate 10 by screws. In other embodiments, the gas-liquid separator 40 has a separator fitting, which is located at the inlet end and communicates with the inlet end, and the inlet end is connected to another flow path or pipeline via the separator fitting.

[0049] According to some embodiments of this disclosure, as shown in Figure 1, the gas-liquid separator 40 and the second flow path plate 20 are located 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. 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 located on the same side to make full use of the space in the integrated module 1 and to improve the integration density of the integrated module 1.

[0050] According to some embodiments of this disclosure, an external device interface includes at least one group of heat exchange plate interfaces 14, each group of which is 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, a plurality of external device interfaces include heat exchange plate interfaces 14, each group of which is 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 it if the battery module's temperature 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, to accelerate the cooling rate of the battery module temperature, and to enable 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, and as a result, pipelines connected to the external device interfaces can be connected to the same side of the integrated module 1, thereby facilitating the overall pipeline layout of the vehicle.

[0052] According to some embodiments of this 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, with the first and second directions being opposite.

The compressor 100, on-board condenser 600, on-board evaporator 700, outdoor condenser 200, refrigerant storage tank 300, heat exchange plate 80, etc. are connected to the refrigerant side of the integrated module 1. The motor-controlled electronic radiator 500, the first radiator 400, etc. are connected to the liquid cooling side of the integrated module 1. The refrigerant in the refrigerant circuit can be converted between a gaseous state and a liquid state under the action of the compressor 100. The thermal management system 10000 has multiple modes, including 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 battery cooling + air conditioning cooling + air conditioning heating mode.

[0059] In battery cooling mode, the compressor 100 discharges high-temperature, high-pressure gaseous refrigerant. The gaseous refrigerant flows into the outdoor condenser 200, where it dissipates heat and liquefies. The medium-temperature, high-pressure liquid refrigerant flows through the first one-way valve 11a and the second one-way valve 11b in sequence to the first throttle valve 12a. The liquid refrigerant is throttled and expands at the first throttle valve 12a, flows out of the integrated module 1 through the heat exchange plate interface 14, and then flows into the heat exchange plate 80. At this time, the low-temperature, low-pressure gas-liquid mixture absorbs heat from the battery and evaporates, thus cooling the battery module if the battery module temperature is too high. After heat exchange, the refrigerant enters the integrated module 1 again through the heat exchange plate interface 14, 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. The above describes the battery cooling mode of the thermal management system 10000. Through the above process, the refrigerant circulates, cooling the battery module.

[0060] In battery heating mode, the compressor 100 discharges high-temperature, high-pressure gaseous refrigerant. The gaseous refrigerant flowing into the integrated module 1 flows to the first solenoid valve 13a. The gaseous refrigerant flows into the heat exchange plate 80 through the heat exchange plate interface 14. At this time, the gaseous refrigerant condenses and dissipates heat, heating the battery module. This heats the battery module, improving battery life and battery efficiency, as well as improving battery capacity and vehicle driving range at low temperatures, and effectively shortening charging time. After heat exchange, the refrigerant enters the integrated module 1 through the heat exchange plate interface 14, is throttled by the first throttling valve 12a, and expands. The liquid refrigerant flows through the third one-way valve 11c to the first heat exchanger interface 15, flows into the heat exchanger 30, absorbs heat, and evaporates. The refrigerant flowing out of the heat exchanger 30 through the second heat exchanger interface 16 flows to the gas-liquid separator 40 through the second solenoid valve 13b. After gas-liquid separation, the refrigerant flows back into the compressor 100. This completes the battery heating mode of the thermal management system 10000.

The refrigerant absorbs heat from the vehicle's interior environment, lowering the temperature inside the vehicle. The low-temperature, low-pressure gaseous refrigerant flows back into the integrated module 1 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 cooling mode of the thermal management system 10000. Through this process, the refrigerant circulates, and the vehicle interior is refrigerated and cooled.

[0062] In the air conditioning heating mode, the compressor 100 discharges high-temperature, high-pressure gaseous refrigerant. The gaseous refrigerant flows into the on-board condenser 600. This refrigerant releases heat in the on-board condenser 600, and this heat is mixed with air and blown into the vehicle by a fan to heat the interior. The refrigerant that flows out of the on-board condenser 600 flows into the integrated module 1, is throttled and expanded by the second throttle valve 12b, and 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 to the second solenoid valve 13b, and then enters 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. Through this process, the refrigerant circulates, and heating is performed inside the vehicle.

[0063] In battery cooling + air conditioning cooling mode, high-temperature, high-pressure gaseous refrigerant is discharged from the compressor 100 and split into two paths. One path flows into the outdoor condenser 200, where the gaseous refrigerant dissipates heat and liquefies. The medium-temperature, high-pressure liquid refrigerant then flows through the first one-way valve 11a and the second one-way valve 11b in sequence to the first throttle valve 12a. The liquid refrigerant is throttled and expands at the first throttle valve 12a, flows out of the integrated module 1 through the heat exchange plate interface 14, and then flows into the heat exchange plate 80. At this time, the low-temperature, low-pressure gas-liquid mixture absorbs heat from the battery and evaporates. After heat exchange, the refrigerant re-enters the integrated module 1 through the heat exchange plate interface 14, flows through the first solenoid valve 13a, and then enters the gas-liquid separator 40. The other path enters the outdoor condenser 200. Gaseous refrigerant flows into the outdoor condenser 200.

[0069] In 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 outdoor condenser 200. The refrigerant is heated and liquefied in the outdoor condenser 200, becoming a medium-temperature, high-pressure liquid refrigerant. The liquid refrigerant flows from the first one-way valve 11a to the third throttling valve 12c for throttling expansion.

[0070] The liquid-cooled integrated module can implement 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 refrigerant from the first radiator 400 flows into the water pump 60 and through the second flow path to the four-way valve. The four-way valve guides the refrigerant to the motor-controlled radiator 500. The refrigerant enters the motor-controlled radiator 500 for heat exchange and then returns to the first radiator 400, realizing the circulating operation of the high-temperature heat dissipation mode.

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

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

[0073] The liquid-cooled integrated module also has a heat absorption / heat dissipation mode. In this configuration, 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 from the first radiator 400 flows into the water pump 60, then through the first flow path to the heat exchanger 30. After heat exchange with the refrigerant in the heat exchanger 30, it flows to the four-way valve. The four-way valve guides the refrigerant to the motor-controlled electronic radiator 500 and the first radiator 400, realizing a circulating operation in the heat absorption / heat dissipation mode.

[0074] The integrated module 1 of this disclosure divides the structures located on the integrated module 1 into a refrigerant side and a liquid-cooled side by setting up a connected first flow path plate 10 and a second flow path plate 20. Structures such as a heat exchanger 30 and a gas-liquid separator 40 are set up in the refrigerant side integrated module, and structures such as a switching valve 50, a water pump 60 and a water replenishment tank 70 are set up in the liquid-cooled side integrated module. Since the gas-liquid separator 40 is located on the same side as the liquid-cooled side integrated module, the interfaces of the refrigerant side integrated module and the liquid-cooled side integrated module are located on both sides of the integrated module, so that the two pipelines do not interfere with each other, simplifying the pipeline layout of the entire vehicle, and making the overall layout of the vehicle more rational and aesthetically pleasing. In this way, the thermal management system 10000 has a compact structure and a higher degree of integration, and can realize a better platform-based design of the entire vehicle. The integrated module 1 as a whole forms a square structure, which can be configured for small vehicles.

[0075] The following is a brief explanation of the thermal management system 10000 described in this disclosure.

[0076] As shown in Figure 5, the thermal management system 10000 according to this disclosure includes the integrated module 1 described in any one of the above embodiments. Because the thermal management system 10000 according to this 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 following is a brief description of the vehicle 1000 described herein.

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

[0079] In short, the integrated module 1 of this disclosure integrates structures such as 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 flow path plate 10 and the second flow path plate 20, thereby increasing the degree of integration. Furthermore, the first flow path plate 10 and the second flow path plate 20, which have internal flow paths and inlet and outlet interfaces, simplify 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 flow path plate 10 and the second flow path plate 20, the refrigerant-side integrated module and the liquid-cooled-side integrated module are distributed on both sides, and the interfaces between the refrigerant-side integrated module and the liquid-cooled-side integrated module are located on both sides of the integrated module 1, so that the two pipelines do not interfere with each other, the pipeline layout of the entire vehicle is simplified, and the overall layout of the vehicle becomes more rational and aesthetically pleasing.
