AI Technical Summary

Technical Problem

Reciprocating compressors in existing refrigerators are prone to generating vibration and radiation noise, which affects the overall quality.

Method used

Design a refrigerator pipe silencer, which adopts a coaxial cavity, an air inlet pipe and an exhaust pipe. The cylinder of the cavity has staggered convex and concave surfaces forming a wave-like structure. The air inlet pipe is filled with porous material. The exhaust pipe connects the flared mouth and the exhaust expansion chamber. The porous material and wave-like structure attenuate the airflow pulsation. The drain channel discharges lubricating oil to prevent solid impurities from entering the exhaust system.

Benefits of technology

It effectively reduces airflow pulsation, lowers noise, prevents solid impurities from entering the exhaust system, and improves refrigeration efficiency.

Abstract

本发明公开了一种冰箱管路消声器。该冰箱管路消声器主要包括同轴设置的腔体、进气管和排气管,腔体的筒体圆柱面上有众多的凸面和凹面,在圆周方向上形成不同高度的波浪状结构,进气管的进气扩张管置于腔体内,排气扩张腔连接有喇叭口的一端置于腔体内。该结构使得气流在进气管中进气扩张管和多孔材料以及波浪状结构筒体壁面的缓冲和衰减作用下,经喇叭口进入排气扩张腔衰减后从排气外接管排入冰箱管道系统,实现削弱气流脉动降低噪声的目的,同时制冷剂中含有的微量润滑油可以从排液通道中排出腔体,而嵌入排气扩张腔内的排气外接管凸出于排气扩张腔底部,可以避免固体杂质排入到排气系统中。
