Abstract

The invention relates to silencing apparatus used to reduce fridge noise pollution. It is connected between fridge evaporator inlet pipe and capillary outlet. And it is made up of three sections silencing tube with constant section. The silencing tube is formed by front, middle, back three cylindrical silencing small tubes. The invention can make the injection noise of the capillary outlet transit constant section to reduce speed, transit tube to stabilize flow, fix capillary outlet to reduce tremor by fully utilizing the silencing principle that flow speed is reduced to reduce injection noise; the flow is stable to reduce wheezing flow; depth of immersion of the capillary outlet is reduced to fix the capillary and reduce its tremor. Thus the whole noise of the fridge can be reduced. The flow noise of the capillary outlet can be greatly reduced. And the structure of the invention is simple; its manufacture and installation are convenient.

Description

technical field [0001] The invention relates to a muffler, in particular to a muffler for reducing the noise at the outlet of a capillary tube of a refrigerator, thereby reducing the noise pollution of the refrigerator. Background technique [0002] The current research on the noise of refrigerators has focused on the research field of the flow noise inside the pipeline of the refrigerator refrigeration system. For refrigerators, the current overall noise level has been stabilized below 40dB (direct cooling refrigerators), and it should be further reduced. The noise level of the refrigerator, in addition to reducing the noise level of the refrigerator compressor, it is necessary to optimize the design of the refrigeration system of the refrigerator to reduce the outlet noise of the capillary tube of the refrigerator. The inventor has studied this problem for a long time, and thinks that the overall noise level of the refrigerator should be lower, and attention must be paid t...
