Novel compressor muffler

Abstract

The invention discloses a novel compressor muffler. The muffler comprises a lower shell, an upper cover matched with the lower shell, a first air guiding pipe, a first vertical partition plate and a second vertical partition plate which are arranged inside the lower shell, and a second air guiding pipe and a cylinder connecting piece which are arranged on the upper cover; a branch noise reductiondevice is arranged inside the first air guiding pipe; the branch noise reduction device comprises a plurality of parallel circular air guiding pieces and a plurality of branch air guiding pipes communicated with the circular air guiding pieces respectively; the circular air guiding pieces are perpendicular to the center axis of the first air guiding pipe separately, the center axes of the branch air guiding pipes are all parallel to the center axis of the first air guiding pipe, and the outer diameters of the circular air guiding pieces are all smaller than the inner diameter of the first airguiding pipe. The muffler has the advantages that gas flow is divided through the branch noise reduction device, and the good buffer effect is achieved; the lower shell and the upper cover are each ofa right-angled 7-shaped structure, sufficient unfolding is achieved, the space of the compressor muffler is enlarged, and the noise reduction effect is enhanced.

Description

technical field [0001] The invention relates to the technical field of compressor mufflers, in particular to a novel compressor muffler capable of increasing the space of the compressor muffler and enhancing the air guiding buffer effect and noise reduction effect. Background technique [0002] A compressor is a driven fluid machine that elevates low-pressure gas to high-pressure gas, and is the heart of the refrigeration system. It inhales low-temperature and low-pressure refrigerant gas from the suction pipe, drives the piston to compress it through the operation of the motor, and discharges high-temperature and high-pressure refrigerant gas to the exhaust pipe to provide power for the refrigeration cycle. [0003] Noise has been regarded as one of the serious pollutions in the world today, and the noise problem of compressors has become an important indicator to measure its comprehensive performance. The main noise source of the compressor is composed of three parts: the...
