[0056] In summary, the implementation principle of the integrated device of the automobile thermal management system in the embodiment is as follows: the automobile thermal management system integrated device has one or more valve integrated units 5, and the valve integrated unit 5 has a refrigerant flow channel inside. The valve integrated unit 5 fixes some functional components, such as an expansion valve, a pressure sensor, a temperature sensor, a liquid tank 53, and a filling valve 9, on the unit. And these functional components are in communication with the flow channel. The valve integrated unit 5 is fixed to the compressor through bolts. And the refrigerant power unit 1 and the refrigerant and coolant heat exchange unit are spliced together through the valve integrated unit 5 and then fixed to the bracket. The refrigerant power unit 1 provides a refrigerant conveying power, and the refrigerant is discharged from the exhaust port 11, conveyed to the coolant and refrigerant heat exchange unit 2 through the flow channel inside the first integrated valve 51, and after the refrigerant and the coolant are heat exchanged in the coolant and refrigerant heat exchange unit 2, the phase-changed refrigerant flows to the liquid tank 53 through the flow channel of the first integrated valve 51. The single-state refrigerant in the liquid tank 53 flows out through the flow channel inside the first integrated valve 51 and then flows to the air charge and enthalpy increase heat exchange module 6 in two ways (the B-way refrigerant directly flows into the air charge and enthalpy increase heat exchange module 6, is heat exchanged inside the air charge and enthalpy increase heat exchange module 6, and then flows back to the compressor; the A-way refrigerant enters the air charge and enthalpy increase heat exchange module 6 after being cut off by the first expansion valve 54, is heat exchanged between refrigerants inside the air charge and enthalpy increase heat exchange module 6, and then flows into the second integrated valve 52 and returns to the refrigerant power unit 11 through the C-way and the D-way. The refrigerant circuit is a closed loop. The refrigerant inlet and outlet ports can be added to the valve integrated unit 6 to expand the function of the system.

[0057] The valve integrated unit 6 can be one or multiple. The coolant and refrigerant heat exchange unit 2 can also be two or multiple. According to the system or functional requirements, the corresponding functional accessories, such as the expansion valve, the pressure sensor, and the temperature sensor, can be added or removed.

[0058] The integrated module is fixed to the whole vehicle through the metal bracket 3, so that the structure is compact and the space volume is small. The integrated module enables the refrigerant to realize a closed loop, so that the refrigerant can be filled in advance, the installation time of the whole vehicle thermal management system during the assembly of the whole vehicle is reduced, and the refrigerant filling time is reduced. At the same time, due to the compactness of the integrated module, the refrigerant volume of the system is reduced, the weight of the refrigerant is reduced, and the cost is reduced.

[0059] The integrated device can also add a coolant power unit and a regulating unit according to the requirements of the automobile thermal management system. Therefore, the integrated device has the characteristics of strong expansibility and wide adaptability.

[0060] The units of the application are relatively independent, and the power unit and the adjusting unit of the cooling liquid can be increased. Moreover, the integrated device has strong expansibility. Therefore, the integrated device has the characteristics of flexibility, diversity, wide adaptability and the like. At the same time, the integrated device greatly reduces the installation time of the whole vehicle heat pump system parts, reduces the cost, and reduces the risk of leakage between the parts. The integrated module unit has high integration degree, strong expansibility, flexible arrangement, can well adapt to the whole vehicle layout of the automobile thermal management system, save space, reduce parts. Subsequent production reduces the working hours, reduces the cost and the like.
