A return air pipe fixing piece

Abstract

A trachea fixing part comprises an annular frame body, a sleeve hole in the inner space of the frame body for passing a trachea pipe through, and several supporting ribs between the frame body and the sleeve hole. The air return pipe fixing part is made by mold-opening injection molding process. Not only is the solid and stable injection molding material selected in the material, but also through the design of the kit structure, it can realize the advantages of instant disassembly and assembly, and the position can be adjusted, which greatly improves the refrigerator. High production efficiency and reduced production cost.

Description

technical field [0001] The invention relates to a fixing piece applied to the air return pipe of a refrigerator, more specifically, an injection molding kit. Background technique [0002] The refrigerator refrigeration system is mainly composed of compressors, condensers, evaporators, return air pipes, capillary tubes and other components. In order to subcool the refrigerant in the capillary and improve the efficiency of the refrigeration system, the method of parallel heat exchange between the capillary and the return pipe is often used to form the return pipe assembly. The air return pipe of the refrigerator is a pipe connecting the outlet of the refrigerator evaporator and the air inlet of the compressor. Its materials are generally copper pipes, aluminum pipes, steel pipes, etc. In addition, capillary tubes are generally designed on the return air pipe for heat exchange, which mainly transfers part of the energy consumption in the air return pipe to the capillary tubes,...

Problems solved by technology

[0005] First: Sponge is a kind of easily deformable material. The kit 3 made of sponge is easy to deform so that the distance between the return air pipe 2 and the inner tank wall or the back panel is too close, resulting in condensation on the inner tank wall and the back panel

[0006] Second: The sponge set is usually a one-time set, which cannot be reused, and in the process of manual setting, it is easy to generate waste and increase production costs

[0007] Third: During the threading process, the sponge kit needs to be inserted from the end of the return air pipe. Once the two ends of the return air pipe are respectively fixed to the evaporator and the compressor, there is no way to insert a new kit into the return air pipe or from the Remove the old kit from the air return line
