Low-noise compressor shell and manufacturing method thereof

Abstract

The invention discloses a low-noise compressor shell and a manufacturing method thereof. The low-noise compressor shell comprises a metal shell body, and a plurality of noise reducing blocks connectedto the metal shell body; the noise reducing blocks are bonded on the metal shell body and comprise metal mass blocks and rubber block layers from outside to inside; and the metal mass blocks and therubber block layers are vulcanized together. When the low-noise compressor shell is manufactured, firstly, the structure of the compressor metal shell body is determined, then vibration response of the metal shell body is calculated, the number and the pasting positions of the noise reducing blocks are determined, the noise reducing blocks are manufactured, and the noise reducing blocks are pasted. According to the low-noise compressor shell and the manufacturing method thereof, pasting is specially conducted on the area with large vibration of the compressor metal shell body, the noise reducing blocks achieve the effects of dynamic vibration absorbing and damping constraint simultaneously, the noise reduction performance is greatly reduced, the weight is low, the cost is low, and the heatdissipation effect is good; and due to local bonding, areas needing to mount pipelines can be avoided, and the manufacturing method is convenient and fast.

Description

technical field [0001] The invention relates to the technical field of compressors, in particular to a low-noise compressor housing and a manufacturing method thereof. Background technique [0002] The air conditioner compressor is the main noise source of the air conditioner. Under most working conditions, the noise of the compressor accounts for more than 80% of the noise energy of the general unit. The noise of the compressor is divided into electromagnetic noise, mechanical noise and aerodynamic noise. These three kinds of noise are all generated inside the compressor, and are transmitted to the outside of the compressor through the compressor shell in the form of vibration or sound waves. Therefore, a low-noise compressor housing is very important to reduce compressor noise. [0003] Traditional low-noise compressor shells generally use multi-layer materials, such as: a shell composed of three layers of materials, with a damping layer in the middle and steel plate laye...
