Oil-gas separator for vehicle-mounted air conditioner compressor and vehicle-mounted air conditioner compressor

Abstract

The present invention discloses an oil-gas separator for a vehicle-mounted air conditioner compressor. The oil-gas separator comprises a shell, a centrifugal separation device and a secondary separation filter cartridge are disposed in the shell from top to bottom and connected via pipelines, and the shell is respectively communicated with the centrifugal separation device and the secondary separation filter cartridge to form an oil gas channel, an exhaust channel and an oil draining channel. Compared with the prior art, the oil-gas separator for a vehicle-mounted air conditioner compressor and the vehicle-mounted air conditioner compressor are reasonable in design and simple in structure, centrifugal type separation is adopted to achieve preliminary separation so as to reduce the oil content of mixed gas at a filter screen, and normal use and filtering efficiency of the secondary separation filter cartridge are ensured; and filter screen type separation is adopted to achieve secondaryseparation to separate lubricating oil from the mixed gas, separation efficiency is high, the proportion of the lubricating oil of an auto air-conditioner compressor participating a refrigerant cycleis reduced, compressor efficiency of the auto air-conditioner compressor is improved, and heat exchange efficiency of a condenser and an evaporator is improved.

Description

technical field [0001] The invention relates to the technical field of vehicle air-conditioning compressors, in particular to an oil-gas separator for a vehicle-mounted air-conditioning compressor and a vehicle-mounted air-conditioning compressor. Background technique [0002] With the development of the automobile manufacturing industry, the research on automobile air conditioning technology is getting faster and faster. The compressor lubricating oil in the refrigeration system of the car air conditioner is a lubricating oil that is miscible with the refrigerant. The car air conditioner compressor compresses the refrigerant during operation, and at the same time a large amount of lubricating oil enters the compressor and is compressed and then discharged directly from the exhaust port. , enter the pipeline, condenser, and evaporator to circulate with the refrigerant, which affects the heat transfer efficiency of the condenser and evaporator, thereby affecting the cooling e...
