Description

[0001] The utility model relates to the technical field of mufflers, in particular to an integrated copper muffler. Background Technique

[0002] During the operation of an air conditioner, its outdoor unit will generate relatively large noises, mainly including refrigerant noise and compressor transmission noise. The so-called compressor transmission noise refers to the vibration generated during the operation of the compressor being transmitted to the indoor unit through the pipeline or the flow of the refrigerant, and the presented sounds include the "hissing" sound of the refrigerant flowing and the high-frequency or low-frequency sounds of the compressor. Currently, most outdoor units of air conditioners are equipped with one or two simple mufflers corresponding to the noise frequency band of the compressor on the pipeline. The existing mufflers are basically composed of a tubular housing, and both ends of the tubular housing are in a necked shape, that is, the inner diameter in the middle of the tubular housing is larger than the inner diameters at both ends of the tubular housing, so as to attenuate or reflect the noise in the pipe by changing the cross-sectional area suddenly. However, a part of the gas will also flow out directly from the outlet pipe, resulting in poor sound insulation effect.

[0003] Therefore, the utility model provides an integrated copper muffler. Content of the Utility Model

[0006] Further, a plurality of partitions are fixed inside the housing, and the plurality of partitions are respectively located between the first sound insulation cavity and the second sound insulation cavity and between the second sound insulation cavity and the third sound insulation cavity.

[0007] Further, a plurality of sound insulation plates are fixed on the partition.
