Abstract
The invention discloses a connecting pipe used between a shell and a liquid receiver of an air compressor and a welding method thereof, which belong to technical field of air conditioner fittings. The connecting pipe comprises an outer pipe and an inner pipe, wherein an outer pipe sleeve is arranged on the outer side of the inner pipe and the inner wall of the outer pipe is in sealed engagement with the outer wall of the inner pipe. The welding method comprises steps of cleaning a welding position of an opening of the shell and resistance-welding the opening of the shell and the outer pipe of the connecting pipe. The connecting pipe employs a structure of double wall tube, and thereby material of low cost and convenient welding process can be used to largely reducing fabrication cost, for example the outer pipe employs steel material and inner pipe keeps using TP2 copper tubes. Compared with existing connecting pipes, the fabrication cost can be decreased by about 79%. The welding method employs resistance welding, which has advantages of low welding cost, low process requirements, saving the acid-washing process and avoiding pollution to environment.
Description
Technical field
The invention belongs to air conditioner accessory technical field, be specifically related to a kind of connecting tube and welding method thereof that is used between air-conditioner compressor outer housing and the cistern.
Background technique
The existing connecting tube that is used between air-conditioner compressor outer housing and the cistern adopts the single tube structure, is the TP2 copper tube, cost cost height; And, the welding method of existing connecting tube comprises cleans compressor pickling after compressor case and connecting tube, compressor case and connecting tube gas brazing or highfrequency welding, the welding, and this method welding cost height, technological requirement height, the pickling after welding easily cause environmental pollution.
Summary of the invention
For overcoming problems of the prior art, the present invention aims to provide that a kind of cost cost is low, welding procedure is simple, the free of contamination connecting tube between air-conditioner compressor outer housing and the cistern and the technological scheme of welding method thereof of being used for.
