Therefore, this application is intended to cover modifications and variations falling within the scope of the corresponding claims (the claimed technical solutions) and their equivalents. It should be noted that the embodiments provided in this application can be combined with each other without contradiction.

[0047] It should be noted that similar labels and letters in the following figures indicate similar items; therefore, once an item is defined in one figure, it does not need to be discussed further in subsequent figures.

[0048] Figure 1 The diagram shown is a structural schematic of the thermal management integrated system provided in an embodiment of this application. Figure 2 The diagram shown is a schematic diagram of the flow channel plate provided in an embodiment of this application.

[0049] This application provides a vehicle that includes a thermal management integrated system. The thermal management integrated system includes an external motor circuit, an external battery circuit, a refrigerant flow path for the vehicle, and a thermal management integrated module 10.

[0050] It is understood that the vehicles provided in the embodiments of this application may be vans, trucks, vehicle-mounted cabins, etc., and this application does not impose specific limitations on them.

[0051] In the vehicle thermal management integrated system provided in this embodiment, the specific structure of the thermal management integrated module 10 is as follows:

[0052] See Figure 1 and Figure 2 The thermal management integrated module 10 includes a flow channel plate 100, a heat exchanger 200, and a pump body. The flow channel plate 100 has multiple built-in flow channels. The heat exchanger 200 and the pump body are both integrated into the flow channel plate 100. The pump body is used to drive the coolant to circulate in the built-in flow channels. At least one built-in flow channel is used to connect with the external motor circuit, and at least one built-in flow channel is used to connect with the external battery circuit. The heat exchanger 200 is located in both the vehicle's refrigerant flow path and the external battery circuit. The flow channel plate 100 is integrally formed.

[0053] In practice, the flow channel plate 100 can be manufactured using 3D printing technology to achieve one-piece molding of the flow channel plate 100, avoiding the need for sealing components at the splicing points and reducing the risk of leakage. In addition, the bottom of the flow channel plate 100 can be connected to the vehicle via the base 101.

[0054] In this embodiment, the flow channel plate 100 serves as a carrier for integrating multiple components. The flow channel plate 100 has multiple built-in flow channels to connect the components integrated within it, forming a circulation loop. A pump body is integrated into the flow channel plate 100, driving the flow of coolant within its flow channels. A heat exchanger 200 is also integrated into the flow channel plate 100. The heat exchanger 200 primarily facilitates heat exchange between the coolant and refrigerant. Located simultaneously in the vehicle's refrigerant flow path and the external battery circuit, the external battery circuit can achieve battery cooling through the heat exchanger 200. The coolant carrying battery heat exchanges heat with the low-temperature refrigerant in the vehicle's refrigerant flow path at the heat exchanger 200, transferring heat to the refrigerant and cooling the battery. This integrated module integrates the thermal management module, connecting the external battery circuit and the external motor circuit through the flow channel plate 100 and its multiple built-in flow channels. The design integrates the external battery circuit and the external motor circuit onto the flow channel plate 100 to form the aforementioned thermal management integrated module 10. Since multiple built-in flow channels integrate the battery circuit and the motor circuit onto the flow channel plate 100, there is no need to install pipes or other components to connect the units of the external battery circuit and the units of the external motor circuit. This reduces the number of parts in the thermal management integrated system, facilitates assembly, and improves assembly efficiency. It also helps to improve the space utilization of the thermal management integrated system and reduces the risk of leakage and failure caused by pipelines, thereby improving the working stability and reliability of the thermal management integrated device.

[0055] See also Figure 1 and Figure 2 In some embodiments, the multiple built-in flow channels include a first flow channel 110 and a second flow channel 120;

[0056] The pump body includes a first water pump 300, which is integrated into the flow channel plate 100;

[0057] The first flow channel 110 is provided with a first battery interface 111 and a heat exchange water inlet interface 112. The first battery interface 111 is used to connect to the water outlet of the external battery circuit, and the heat exchange water inlet interface 112 is used to connect to the water inlet end of the heat exchanger 200.

[0058] The second flow channel 120 is provided with a second battery interface 121, a first water pump interface 122 and a heat exchange water outlet interface 123. The second battery interface 121 is used to connect to the water inlet of the external battery circuit, the heat exchange water outlet interface 123 is used to connect to the water outlet end of the heat exchanger 200, and the first water pump interface 122 is used to connect to the first water pump 300. The first water pump 300 is used to drive the flow of coolant.

[0059] In this embodiment, the coolant from the external battery circuit enters the first flow channel 110 through the outlet of the external battery circuit and the first battery interface 111. Then, it enters the heat exchanger 200 through the inlet and heat exchange inlet interface 112 to cool down and transfer heat. It then enters the second flow channel 120 through the outlet and heat exchange outlet interface 123 of the heat exchanger 200, continues to flow through the first water pump 300 to the second battery interface 121, and finally flows back into the battery circuit through the inlet of the external battery circuit, thus cooling the battery. The above path constitutes the battery coolant circulation path. The first water pump 300 drives the coolant to flow in the above battery coolant circulation path, keeping a continuous flow of low-temperature coolant to the inlet of the external battery circuit and transferring the high-heat coolant flowing from the outlet of the external battery circuit to the heat exchanger 200.

[0060] See Figure 1 and Figure 2 In some embodiments, the second flow channel 120 is further provided with a first temperature sensing interface 124; the flow channel plate 100 integrates a first temperature sensor 400; the first temperature sensor 400 is connected to the first temperature sensing interface 124 to allow its sensing end to contact the coolant in the second flow channel 120. Thus, the first temperature sensor 400 can measure the temperature of the coolant in the second flow channel 120, which is beneficial for controlling the temperature of the coolant in the second flow channel 120.

[0061] See Figure 1 and Figure 2 In some embodiments, the multiple built-in flow channels also include an expansion flow channel 130, which is provided with a battery expansion interface 131 for connecting to a battery cooling expansion tank.

[0062] Understandably, the operating pressure within the flow channel fluctuates at different times, and the pressure in the battery coolant circulation path at 300 RPM of the first water pump also varies. When the pressure in the battery coolant circulation path fluctuates, the battery cooling expansion tank can play a stabilizing role. Under different ambient temperatures, the volume of the liquid medium in the battery coolant circulation path changes, and the battery cooling expansion tank provides expansion space to accommodate these volume changes.

[0063] Figure 3 The diagram shown is a schematic diagram of the connection structure between the thermal management integrated module and the compressor provided in an embodiment of this application.

[0064] See Figures 1 to 3 In some embodiments, the refrigerant flow path of the vehicle includes an electronic expansion valve 41, a compressor 42, and a condenser 43;

[0065] The electronic expansion valve 41 is integrated into the flow channel plate 100, and the multiple built-in flow channels also include a third flow channel 140, a fourth flow channel 150 and a fifth flow channel 160;

[0066] The third flow channel 140 is provided with a first heat exchange refrigerant interface 141 and a first compression interface 142. The first heat exchange refrigerant interface 141 is used to connect to the refrigerant outlet end of the heat exchanger 200, and the first compression interface 142 is used to connect to the inlet end of the compressor 42.

[0067] The fourth flow channel 150 is provided with a second compression port 151 and a first condensation port 152. The second compression port 151 is used to connect to the outlet end of the compressor 42, and the first condensation port 152 is used to connect to the inlet end of the condenser 43.

[0068] The fifth flow channel 160 is provided with a second heat exchange refrigerant interface 161, a second condensation interface 162 and a valve interface 163. The second heat exchange refrigerant interface 161 is used to connect to the refrigerant inlet end of the heat exchanger 200, the second condensation interface 162 is used to connect to the outlet of the condenser 43, and the valve interface 163 is used to connect to the electronic expansion valve 41 to control the coolant flow rate.

[0069] In this embodiment, the coolant transmitted by the external battery circuit heats the refrigerant inside the heat exchanger 200 when it passes through the heat exchanger 200. The heated refrigerant enters the third flow channel 140 through the refrigerant outlet end of the heat exchanger 200 and the first heat exchange refrigerant interface 141, and then enters the compressor 42 through the inlet end of the compressor 42. Then, driven by the compressor 42, the refrigerant enters the fourth flow channel 150 through the outlet end of the compressor 42 and the second compression interface 151. The refrigerant enters the condenser 43 through the fourth flow channel 150 and through the first condensation interface 152 and the inlet end of the condenser 43. The condenser 43 can cool the refrigerant. The cooled refrigerant enters the fifth flow channel 160 through the outlet end of the condenser 43 and the second condensation interface 162, and then reaches the electronic expansion valve 41. After the electronic expansion valve 41 depressurizes the refrigerant, it flows back to the heat exchanger 200 through the second heat exchange refrigerant interface 161 and the refrigerant inlet end of the heat exchanger 200.

[0070] Figure 4 The diagram shown is a schematic representation of the connection structure between the condenser and the radiator provided in an embodiment of this application. Figure 5 The diagram shown is an exploded view of the connection structure of the condenser and radiator provided in an embodiment of this application.

[0071] See Figures 1 to 5 In some embodiments, the plurality of built-in channels also include a sixth channel 170 and a seventh channel 180;

[0072] The sixth flow channel 170 is provided with a first motor interface 171 and a first heat dissipation interface 172. The first motor interface 171 is used to connect with the water outlet of the external motor circuit, and the first heat dissipation interface 172 is used to connect with the water inlet end 60a of the radiator.

[0073] The seventh flow channel 180 is provided with a second heat dissipation interface 181, a second motor interface 182, and a second water pump interface 183 located between the second heat dissipation interface 181 and the second motor interface 182. The second heat dissipation interface 181 is used to connect to the outlet end 60b of the radiator, the second motor interface 182 is used to connect to the inlet of the external motor circuit, and the second water pump interface 183 is used to connect to the second water pump 500, which is used to drive the flow of coolant.

[0074] In this embodiment, the coolant from the external motor circuit enters the sixth flow channel 170 through the outlet of the external motor circuit and the first motor interface 171, and then enters the radiator 60 through the first heat dissipation interface 172 and the inlet end 60a of the radiator. The radiator 60 can cool the coolant. After cooling, the coolant enters the seventh flow channel 180 through the outlet end 60b of the radiator and the second heat dissipation interface 181. The coolant is driven to flow by the second water pump 500. Finally, the coolant flows back to the external motor circuit through the second motor interface 182 and the inlet of the external motor circuit to cool the motor. The above path constitutes the motor coolant circulation path. The second water pump 500 drives the coolant to flow in the above motor coolant circulation path, keeping a continuous flow of low-temperature coolant to the inlet of the external motor circuit and transferring the high-heat coolant flowing from the outlet of the external motor circuit to the radiator 60.

[0075] See Figure 2 and Figure 3 In some embodiments, the seventh flow channel 180 is also provided with a motor expansion interface 184, which is located between the second heat dissipation interface 181 and the second water pump interface 183. The motor expansion interface 184 is used to connect to the motor cooling expansion tank.

[0076] Understandably, the pressure within the flow channel fluctuates at different times, and the pressure in the motor coolant circulation path at 500 RPM of the second water pump also varies. When the pressure in the motor coolant circulation path changes and fluctuates, the motor cooling expansion tank can play a stabilizing role. Under different ambient temperatures, the volume of the liquid medium in the motor coolant circulation path will change, and the motor cooling expansion tank provides expansion space to accommodate these volume changes.

[0077] See Figure 2 and Figure 3In some embodiments, the seventh flow channel 180 is further provided with a second temperature sensing interface 185, which is located between the second motor interface 182 and the second water pump interface 183; the flow channel plate 100 integrates a second temperature sensor 900; the second temperature sensor 900 is connected to the second temperature sensing interface 185 to allow its sensing end to contact the medium inside the seventh flow channel 180. Thus, the first temperature sensor 400 can measure the temperature of the coolant inside the seventh flow channel 180, which is beneficial for controlling the temperature of the coolant inside the seventh flow channel 180.

[0078] For specific implementation, see Figure 1 and Figure 2 The condenser 43 and radiator 60 are located on the side of the thermal management integrated module 10. Meanwhile, the first condensing interface 152 and the second condensing interface 162 are located on the side close to the condenser 43. The first condensing interface 152 and the inlet end of the condenser 43 are connected through the first pipe 601, and the second condensing interface 162 and the outlet end of the condenser 43 are connected through the second pipe 602. The first heat dissipation interface 172 and the second heat dissipation interface 181 are located on the side close to the radiator 60. The first heat dissipation interface 172 is connected to the water inlet end 60a of the radiator through the third pipe 603, and the second heat dissipation interface 181 is connected to the water outlet end 60b of the radiator through the fourth pipe 604. In this way, the length of the pipes is reduced, costs are saved, and the risk of leakage is reduced.

[0079] For specific implementation, see Figure 1 , Figure 4 and Figure 5 To improve heat dissipation efficiency, an electronic fan 800 can also be installed on the side of the radiator 60 away from the condenser 43. In specific installation, the electronic fan 800 can be installed on the fan cover 801, which is directly connected to the side of the radiator 60 away from the condenser 43.

[0080] See Figure 1 and Figure 4 The condenser 43 and the radiator 60 can be located on the same side of the width direction of the flow channel plate 100. To improve structural stability, they can also be fixedly connected by a fixing plate 701. See [link / reference] Figure 1 and Figure 3 The compressor 42 can be installed on one side of the flow channel plate 100 along its length. The inlet end of the compressor 42 is connected to the first compression port 142 through the fifth pipe 605, and the outlet of the compressor 42 is connected to the second compression port 151 through the sixth pipe 606. The second compression port 151 is located on the side of the flow channel plate 100 near the compressor 42. The first compression port 142 is located on the side of the flow channel plate 100 near the compressor 42, which helps to shorten the length of the fifth pipe 605 and the sixth pipe 606.

[0081] In some embodiments, the thermal management integrated system is located in the vehicle chassis, while the motor cooling expansion tank and the battery cooling expansion tank are located at the top of the vehicle.
