[0060] Figure 2 for Figure 1 Front view; Figure 3 for Figure 1 Rear view of Figure 4 for Figure 2 A partial cross-sectional view of Figure 5 for Figure 3 A partial cross-sectional view of the Figures 1 to 5The embodiment of the present invention provides an automobile thermal management system 100, including a coolant circuit assembly 110, a refrigerant circuit assembly 120 and a heat exchange assembly 130, wherein the coolant circuit assembly 110 includes a coolant circuit substrate 111 and a first circuit assembly 112, wherein a plurality of first coolant channels 1111 for coolant circulation are formed in the coolant circuit substrate 111, and the first circuit assembly 112 is disposed on an outer wall of the coolant circuit substrate 111, and the first circuit assembly 112 includes a first valve 1121, which is connected to the first coolant channel 1111, and the first valve 1121 is used to control the on-off state of the first coolant channel 1111; the refrigerant circuit assembly 120 includes a first circuit assembly 112, and a first circuit assembly 1121 is provided to connect the first coolant channel 1111 to the first coolant channel 1111; and the first circuit assembly 1121 is used to connect the first coolant channel 1111 to the first coolant channel 1111; and the refrigerant circuit assembly 120 includes a first circuit assembly 112, wherein the first circuit assembly 112 includes a first circuit assembly 1121, wherein the first circuit assembly 1121 is connected to the first coolant channel 1111, and the first circuit assembly 1121 is used to control the on-off state of the first coolant channel 1111; and 0 includes a refrigerant circuit substrate 121 and a second circuit assembly 122. A plurality of first refrigerant channels 1211 for circulating refrigerant are formed in the refrigerant circuit substrate 121. The second circuit assembly 122 is arranged on the outer wall of the refrigerant circuit substrate 121. The second circuit assembly 122 includes a second valve 1221. The second valve 1221 is connected to the first refrigerant channel 1211. The second valve 1221 is used to control the on-off state of the first refrigerant channel 1211. The heat exchange assembly 130 is connected between the coolant circuit assembly 110 and the refrigerant circuit assembly 120. The heat exchange assembly 130 is used to perform heat exchange between the coolant circuit assembly 110 and the refrigerant circuit assembly 120.

[0061] The cooling liquid circuit substrate 111 may be made of metal material, such as steel. The cooling liquid may be water, which is not only easily available, but also has a large specific heat capacity and a strong ability to carry heat.

[0062] During implementation, the interior of the coolant circuit matrix 111 can be opened up into interconnected first coolant channels 1111, which extend to the outer wall of the coolant circuit matrix 111 and are connected to the first circuit assembly 112 (such as the first valve 1121) provided at the outer wall, so that the coolant in the first coolant channel 1111 can be controlled by the first valve 1121 to flow out from different positions on the outer wall of the coolant circuit matrix 111, or the flow direction of the coolant inside the coolant circuit matrix 111 can be changed, so as to facilitate the introduction of the coolant into the parts of the car that need to adjust the temperature in the future. Similarly, the refrigerant circuit assembly 120 and the heat exchange assembly 130 can be integrated in a similar manner to the coolant circuit assembly 110. With such an arrangement, the complicated and cumbersome separate manufacturing and assembly processes of the coolant and refrigerant pipes in the prior art are avoided, saving time and cost. At the same time, due to the use of such integrated technology, the overall structure of the automotive thermal management system 100 becomes compact, saving space in the vehicle. In addition, since the coolant pipes and the refrigerant pipes are directly processed inside the substrate, the coolant pipes and the refrigerant pipes are more reliable and more durable.

[0063] It should be noted that the main function of the refrigerant circuit assembly 120 is to produce refrigerants of different temperatures, and the main function of the coolant circuit assembly 110 is to transport the coolant to the place in the car where the temperature needs to be adjusted. Specifically, when the temperature of a certain part of the car is low and needs to be increased, the temperature of the refrigerant will rise appropriately, and the refrigerant will transfer its heat to the coolant in the heat exchange assembly 130, so that the temperature of the coolant will also rise. The coolant with the increased temperature is then transported to the place in the car that needs to be heated up through the coolant circuit assembly 110 to complete the temperature adjustment of the part of the car. When the temperature of a certain part of the car is low and needs to be lowered, the principle is similar to the above process and will not be repeated here.

[0064] like Figure 4 As shown, specifically, a second cooling liquid channel 131 and a second refrigerant channel 132 may be formed in the heat exchange component 130, the second cooling liquid channel 131 is connected to the first cooling liquid channel 1111, and the second refrigerant channel 132 is connected to the first refrigerant channel 1211; the coolant in the second cooling liquid channel 131 and the refrigerant in the second refrigerant exchange heat to adjust the temperature of the coolant in the second cooling liquid channel 131 and the temperature of the coolant in the first cooling liquid channel 1111. When the temperature of a certain part of the car is low and needs to be raised, the temperature of the refrigerant in the first refrigerant channel 1211 will rise appropriately, so that the temperature of the refrigerant in the second refrigerant channel 132 connected to the first refrigerant channel 1211 will also rise accordingly. At this time, the heat of the refrigerant in the second refrigerant channel 132 in the heat exchange component 130 can be transferred to the coolant in the second coolant channel 131. The second coolant channel 131 is connected to the first coolant channel 1111, that is, the temperature of the coolant in the first coolant channel 1111 will also rise, and then the coolant circuit component 110 will transport the coolant in the first coolant channel 1111 to the part of the car that needs to be heated up to adjust the temperature of the part. When the temperature of a certain part of the car is low and needs to be lowered, the principle is similar to the above process and will not be repeated here.

[0065] The first valve 1121 may include a five-way valve and a three-way valve, and the second valve 1221 may include an expansion valve, a first solenoid valve, a second solenoid valve and a one-way valve.

[0066] The automotive thermal management system 100 provided by the embodiment of the present invention simplifies the structure of the existing automotive thermal management system 100 by integrating the pipes of the coolant and the refrigerant in the base body, thereby reducing the manufacturing difficulty and cost of the automotive thermal management system 100.

[0067] In the above embodiment, a coolant container 1122 may be further provided on the coolant circuit substrate 111, and the coolant container 1122 is in communication with the first coolant channel 1111 in the coolant circuit substrate 111. The coolant container 1122 is mainly used to store coolant to replenish the consumption of coolant, and the coolant container 1122 may be directly fixed to the coolant circuit substrate 111 by bolts. A sealing cover 11221 may be provided on the coolant container 1122. On the one hand, the sealing cover 11221 may be used to add coolant to the coolant container 1122. On the other hand, since the coolant container 1122 is in communication with the first coolant channel 1111, the sealing cover 11221 may be loosened to appropriately reduce the pressure of the coolant in the first coolant passage.

[0068] like Figure 3 As shown, the first circuit component 112 may also include a water pump 1123, which is connected to the first coolant channel 1111 in the coolant circuit matrix 111, and the water pump 1123 is used to input the coolant into the required circuit to adjust the temperature of the automotive components at the required circuit. Specifically, the water pump 1123 can be fixedly connected to the outer wall of the coolant circuit matrix 111 by bolts, and the water pump 1123 extracts the coolant in the first coolant channel 1111, and then transports the coolant to the part of the car that needs to adjust the temperature. The water pump 1123 acts on the coolant, which can provide power for the coolant to circulate in each channel.

[0069] Specifically, the water pump 1123 may include a first water pump 11231, a second water pump 11232, and a third water pump 11233, and the first water pump 11231, the second water pump 11232, and the third water pump 11233 may be arranged on the same side of the coolant circuit substrate 111; wherein the first water pump 11231 is used to input the coolant into the circuit where the automobile engine is located to adjust the temperature of the automobile engine; the second water pump 11232 is used to input the coolant into the circuit where the automobile battery is located to adjust the temperature of the automobile battery; and the third water pump 11233 is used to input the coolant into the circuit where the automobile cab is located to adjust the temperature in the automobile cab. wherein the first water pump 11231, the second water pump 11232, and the third water pump 11233 are arranged on the same side of the coolant circuit substrate 111 to reduce the overall size of the coolant circuit assembly 110 to save space in the vehicle.

Specifically, when the first temperature sensor detects that the temperature of the coolant is too low, the temperature of the refrigerant may be appropriately increased to transfer heat to the coolant through the refrigerant to increase the temperature of the coolant; similarly, when the first temperature sensor detects that the temperature of the coolant is too high, the temperature of the refrigerant may be appropriately reduced to cool the coolant through the refrigerant.

[0071] like Figure 2 As shown, during implementation, the second circuit component 122 may further include a second sensor component 1222 , and the second sensor component 1222 includes at least a second temperature sensor 12221 , and the second temperature sensor 12221 is used to detect the temperature of the refrigerant in the first refrigerant channel 1211 .

[0072] In the above embodiment, the second sensor assembly 1222 may further include a pressure sensor 12222, and the pressure sensor 12222 is used to detect the pressure of the refrigerant in the first refrigerant channel 1211. It should be understood that the way to increase the temperature of the refrigerant is generally to pressurize it and do work, so the pressure sensor 12222 can detect the pressure of the refrigerant at any time.
