Description

Technical Field

[0001] This utility model relates to the technical field of thermal management systems, and in particular to a refrigerant-side integrated module. Background Technology

[0002] With the development of new energy vehicles, the energy efficiency of vehicle thermal management systems is becoming increasingly important, as it directly affects the driving range of electric vehicles. The refrigerant side valve plate is one of the important components in the automotive air conditioning thermal management integrated module.

[0003] Existing refrigerant-side integrated modules, such as the refrigerant-side valve plate disclosed in utility model patent application number 202420222112.0 for use in automotive air conditioning thermal management integrated modules, mainly include a valve plate body formed by die casting, multiple flow channel grooves and installation interfaces communicating with the flow channel grooves on the end face of the valve plate body, a welding plate welded on the valve plate body, the end face of the welding plate forming a flow channel for refrigerant to flow with the flow channel grooves, and multiple air conditioning pipe interfaces welded to the outside of the welding plate, which communicate with the flow channel; in use, the air conditioning pipe interfaces are integrated components, integrating multiple interface parts together.

[0004] However, most existing thermal management systems for new energy vehicles have complex and heavy piping, and require large amounts of refrigerant. This not only increases production costs but also reduces system reliability and operating efficiency. Furthermore, maintenance costs are high, the decentralized structure makes troubleshooting difficult, and component replacement requires disassembling multiple pipelines. Existing valve islands also mostly use profile machining processes, which require a large amount of material to be cut from solid profiles, resulting in a large machining allowance and time consumption. Utility Model Content

[0005] To solve the above-mentioned technical problems, this utility model provides a refrigerant-side integrated module that integrates all the most complex and core flow path control into a single refrigerant-side integrated module, achieving a major breakthrough in space utilization, flow channel efficiency, and modularity. It is particularly suitable for modern thermal management systems where space is extremely valuable.

The sub-expansion valve is assembled and integrated with the refrigerant-side valve plate assembly as a carrier. By controlling the opening and closing of the valve components, different modes can be switched to apply to different scenarios. The refrigerant-side valve plate assembly has an extremely compact structure. As an independent module, it can be produced and tested independently and flexibly matched with the flow channel plate. The three-dimensional installation method greatly reduces the planar space occupied. Moreover, its manufacturing process is advanced and economical. The selected die-casting and machining process is particularly suitable for the complex structure of this module, realizing efficient, low-cost, and lightweight production. The same module can simultaneously realize the functions of refrigerant diversion and hot gas bypass.

[0007] Preferably, the refrigerant side valve plate assembly includes a refrigerant side valve plate, a welding plate, a gas-liquid separator connector, a battery cooler connector, and a connector. The refrigerant side valve plate and the welding plate are welded together by vacuum brazing.

The refrigerant-side valve plate has five standardized installation interfaces, and four interfaces are welded to the outside of the refrigerant-side valve plate.

[0009] Preferably, the refrigerant side valve plate is made of aluminum alloy. Aluminum alloy is easy to process. The blank is manufactured by vacuum high pressure die casting process, so that the internal multi-branch flow channels are formed in one step, and then the valve seat and interface are formed by processing.

[0010] Preferably, the internal flow channel connections of the refrigerant-side valve plate are as follows: the first flow channel connects to the refrigerant three-way valve assembly, the outdoor condenser inlet connector, and the shut-off valve assembly; the second flow channel connects to the compressor outlet connector and the refrigerant three-way valve assembly; the third flow channel connects to the refrigerant three-way valve assembly, the indoor condenser inlet connector, and the first check valve assembly; the fourth flow channel connects to the first check valve assembly, the shut-off valve assembly, and the first electronic expansion valve; the fifth flow channel connects to the first check valve assembly, the second check valve assembly, the battery cooler outlet, and the gas-liquid separator interface; the sixth flow channel connects to the fourth electronic expansion valve and the battery cooler inlet; the seventh flow channel connects to the second, third, fourth, and fifth electronic expansion valves; the eighth flow channel connects to the outdoor condenser outlet connector and the second electronic expansion valve; the ninth flow channel connects to the evaporator inlet connector and the fourth electronic expansion valve; the tenth flow channel connects to the indoor condenser outlet connector and the fifth electronic expansion valve; and the eleventh flow channel connects to the evaporator outlet connector and the first check valve assembly.

[0011] Compared with the prior art, the beneficial effects of this utility model are as follows: the refrigerant side valve plate assembly has an extremely compact structure. As an independent module, it can be produced and tested independently and flexibly matched with the flow channel plate. The three-dimensional installation method greatly reduces the planar space occupied. Moreover, its manufacturing process is advanced and economical. The preferred die-casting and machining process is particularly suitable for the complex structure of this module, realizing efficient, low-cost, and lightweight production. The refrigerant diversion and hot gas bypass functions can be realized simultaneously within the same module. Attached Figure Description
