LIQUID STORAGE AND OIL SEPARATION DEVICE, COMPRESSOR ASSEMBLY, HEAT EXCHANGE SYSTEM AND ELECTRICAL EQUIPMENT

摘要

A liquid storage and oil separation device, a compressor assembly, a heat exchange system and electrical equipment. The liquid storage and oil separation device comprises a housing (1) and a partition assembly provided in the housing (1). The top surface of the housing (1) is insertably provided with a first connection pipe (3) and a second connection pipe (4), the bottom surface is insertably provided with a third connection pipe (5) and a fourth connection pipe (6), and the part of the third connection pipe (5) extending into the housing (1) is provided with an oil return hole (5.1). The partition assembly is used to divide the housing (1) into a gas-liquid separation chamber (1.1) and an oil separation chamber (1.2). There is a cavity (2.3) at the inner part of the partition assembly, and the lower part of the partition assembly is provided with an oil-through hole (2.4) used for connecting the gas-liquid separation chamber (1.1) and the oil separation chamber (1.2). The first connection pipe (3) and the third connection pipe (5) separately communicate with the gas-liquid separation chamber (1.1); the second connection pipe (4) and the fourth connection pipe (6) separately communicate with the oil separation chamber (1.2); and a port of the fourth connection pipe (6) extending into the housing (1) is located above the oil-through hole (2.4) and the oil return hole (5.1). Not only may gas-liquid separation and oil separation be achieved and installation space be saved, but the intake air temperature of a compressor may also be prevented from being too high by means of providing the cavity (2.3) in the partition assembly for heat insulation.
