Abstract
The utility model relates to plug-in type stainless steel tube and copper pipe welding structure, feature be include copper pipe and stainless steel tube；It is equipped with the mouth that rises in one end of copper pipe, the outer diameter of stainless steel tube and the outer diameter of copper pipe are identical, and one end of stainless steel tube is inserted in the mouth that rises, and the outer wall of stainless steel tube and the inner wall for the mouth that rises have gap that can be filled in gap so as to solder.Its advantage is that: copper pipe is welded on stainless steel tube, and for copper pipe in conjunction with stainless steel tube, pipeline is cheap, and air-conditioning cost decline, stainless steel tube has more outstanding oxidation resistance and resistance to corrosion compared with copper pipe, improves the service life of air-conditioning duct.
Description
Technical field
The utility model relates to a kind of plug-in type stainless steel tube and copper pipe welding structures.
Background technique
Currently, the pipeline in air-conditioning is copper pipe, the inlet tube and outlet of condenser in the air-conditioning sold on the market
And the inlet tube and outlet of evaporator are copper products, the inlet and outlet pipe and evaporator of copper pipe and condenser into
Mouth and outlet are copper products, although being easy welding, the specific gravity of copper pipe is larger, involves great expense, to make the cost of air-conditioning
Go up.
Summary of the invention
It provides a kind of copper pipe the purpose of the utility model is to overcome the deficiencies in the prior art to be welded on stainless steel tube, copper
For pipe in conjunction with stainless steel tube, pipeline is cheap, declines air-conditioning cost, and stainless steel tube has more outstanding antioxygen compared with copper pipe
Change ability and resistance to corrosion improve the plug-in type stainless steel tube and copper pipe welding structure of the service life of air-conditioning duct.
In order to achieve the above object, the technical solution of the utility model is achieved in that it is that a kind of plug-in type is stainless
Steel pipe and copper pipe welding structure, characterized by comprising:
Copper pipe；The mouth that rises is equipped in one end of the copper pipe；And
Stainless steel tube；The outer diameter of the stainless steel tube and the outer diameter of copper pipe are identical, and one end of stainless steel tube is inserted in the mouth that rises,
And the outer wall of stainless steel tube and the inner wall for the mouth that rises have gap that can be filled in gap so as to solder.
In the technical scheme, the length of the mouth that rises is 0.5-0.8cm.
In the technical scheme, the width in the gap is 0.1-0.2mm.
The utility model compared with prior art the advantages of are as follows: copper pipe is welded on stainless steel tube, copper pipe and stainless steel tube
In conjunction with pipeline is cheap, the decline of air-conditioning cost, and stainless steel tube has more outstanding oxidation resistance and anticorrosive compared with copper pipe
Ability improves the service life of air-conditioning duct.
