A sound-absorbing package for an air-conditioning compressor

Abstract

The invention discloses a sound-absorbing bag used on an air-conditioning compressor, which belongs to the technical field of air-conditioning, and aims to provide a sound-absorbing bag used on an air-conditioning compressor with a good sound-absorbing effect, which includes an air intake pipe connected in sequence and a first cylinder The body, the second cylinder and the air outlet pipe, the first cylinder is provided with an offset device, the second cylinder is provided with a reflection device, the offset device includes an offset plate sliding in the first cylinder, the offset plate and the air inlet of the air intake pipe Correspondingly, the offset plate slides in the axial direction of the first cylinder, and a ventilation space is formed between the outer edge of the offset plate and the inner wall of the first cylinder. In the ring, the connecting ring is connected with the second cylinder, the reflecting plate is in the shape of a bowl and the reflecting port of the reflecting plate is facing the offset plate, and a through hole is opened on the connecting ring.

Description

technical field [0001] The present invention relates to an air conditioner, more specifically, it relates to a sound-absorbing package used on an air-conditioner compressor. Background technique [0002] At present, there are two forms of air-conditioning silencers on the market: full copper silencers and copper-steel silencers. Among them, the whole copper silencer package is made of copper as a whole. Due to the high price of copper, the cost of the silencer package with this structure is relatively high; the material used in the middle part of the copper-steel silencer package is steel, and the two ends are connected The material of the pipe part is copper, and the parts are connected together by welding. The middle part of the sound-absorbing bag with this structure uses steel instead of copper. [0003] Most of the existing noise reduction packages on the market have a hollow cylindrical middle part, and the diameter of the middle part is much larger than the diameter ...

Problems solved by technology

[0004] However, the sound-absorbing effect of the sound-absorbing package set up in this way is not ideal, so some manufacturers have made many improvements to the sound-absorbing part, such as coating the middle part with sound-absorbing materials, or changing the structure of the middle part and the connecting pipe, but the sound-absorbing effect is not as good. not ideal
