Abstract

The invention provides a filter screen support, a liquid accumulator and a compressor, the filter screen support comprises N layers of partition plates connected in sequence and at least one flow guide channel penetrating through the N layers of partition plates, an air cavity is formed between any two adjacent layers of partition plates, and N is a positive integer and is larger than or equal to 2; a separator is arranged between the flow guide channel and the air cavity; the first layer of partition plate in the N layers of partition plates is close to the position where an air suction port of the liquid storage device is located, each layer of partition plate from the second layer of partition plate to the Nth layer of partition plate is provided with at least one air inlet hole, and the air inlet holes are communicated with the air cavity; and an air outlet hole connected with an air outlet pipe of the liquid storage device is formed in the Nth partition plate. According to the filter screen support, noise transmission loss in the liquid storage device can be increased, the noise reduction effect of the liquid storage device can be improved, flowing noise of refrigerants can be reduced, the effective flow guiding effect on the refrigerants in the liquid storage device can be achieved, and flowing loss in the liquid storage device can be reduced.

Description

technical field [0001] The invention relates to the technical field of compressors, in particular to a filter screen support, a liquid accumulator and a compressor. Background technique [0002] The compressor is mainly composed of a cylinder block, a motor, a casing and a liquid accumulator. The liquid accumulator is connected to the air conditioning pipeline and the compressor suction port, and the liquid accumulator is used to prevent the liquid refrigerant of the air conditioning system from entering the compressor cylinder block. Internally, when the liquid refrigerant enters the compressor cylinder, the risk of liquid hammer is likely to occur, thereby affecting the reliability of the system. A filter screen is installed in the liquid accumulator, and the filter screen is used to filter impurities to prevent impurities from entering the compressor. damage the compressor. In addition, the reservoir can also play a role in reducing noise in certain frequency bands. The...
