Problems solved by technology

[0003] 1. If the sound insulation cotton package is not tight, there will be sound leakage, which will reduce the sound quality of the outdoor unit;
[0004] 2. The vibration reduction of the pipeline is not fully considered, and the vibration is attenuated only through the structure of the pipeline itself, such as setting a U-bend

Abstract

The invention provides a vibration and noise reduction device of a compressor. The vibration and noise reduction device of the compressor comprises a surrounding wall, a mounting cavity used for mounting the compressor is formed in the surrounding wall, the surrounding wall comprises a sealed shell, a sound absorption layer and a sound insulation layer, the sound absorption layer is arranged on the inner side of the sealed shell, the sound insulation layer is arranged between the sealed shell and the sound absorption layer, and sound wave energy decrement holes are formed in the sound insulation layer. The noise reduction function of the vibration and noise reduction device of the compressor can be improved.

Description

technical field [0001] The invention relates to the technical field of vibration reduction and noise reduction, and more specifically, to a vibration reduction and noise reduction device for a compressor. Background technique [0002] At present, the noise reduction method of the outdoor unit of the air conditioner is mainly to reduce the noise radiation by wrapping the sound insulation cotton around the compressor, and attenuating the vibration transmitted to the chassis by installing a vibration-damping rubber pad at the bottom, thereby reducing the noise radiation. This method of vibration and noise reduction has the following problems: [0003] 1. If the sound insulation cotton package is not tight, there will be sound leakage, which will reduce the sound quality of the outdoor unit; [0004] 2. The vibration reduction of the pipeline is not fully considered, and the vibration is attenuated only through the structure of the pipeline itself, such as setting a U-bend. C...
