Description

Technical Field

[0002] The basic principle of the refrigeration cycle of the electric vehicle air conditioning system is similar to that of household air conditioning, including four stages: compression, condensation, expansion and evaporation. The refrigerant circulates in the system, and the electronic compressor compresses the refrigerant to make it a high-temperature and high-pressure gas, which then releases heat to the outside air in the condenser and becomes a liquid. It then passes through the expansion valve (or expansion tube) to throttle and becomes a low-temperature and low-pressure gas-liquid mixture, which enters the evaporator to absorb the heat in the car and evaporate, thereby achieving cooling.

[0003] The connecting valve assembly of the electric vehicle air-conditioning system is a collection of key components to ensure the smooth operation of the refrigeration cycle. It integrates multiple functions such as managing refrigerant flow, pressure control, and system protection. In the prior art, the connecting valve assembly of the electric vehicle air-conditioning usually connects the body to the component pipeline through a screw sleeve and a nut. However, the internal installation space of the electric vehicle air-conditioning system is small. When installing and disassembling the connecting valve assembly, it is usually necessary to use a wrench to operate in the narrow space, which makes assembly difficult. Utility Model Content
