Problems solved by technology

Most of the air-conditioning connecting pipes currently used have not treated the surface of the copper pipes, which leads to corrosion of the copper pipes after a period of use, which seriously shortens the service life of the connecting pipes
Even if some protective layers are wrapped on the surface of the copper pipes, one layer of these protective layers is made of rubber rubber material, and its temperature resistance can usually only reach 80°C-90°C. The resulting temperature is 110°C-120°C. Therefore, the above protective layer will have surface cracking and fragmentation after 2-3 years of use, which will seriously affect the life of the air conditioner.

Embodiment Construction

[0011] refer to figure 1 , an air conditioner connecting pipe of the present invention, comprising a copper pipe 1, a pipe joint 2 and a protective layer wrapped on the outside of the copper pipe. The protective layer includes an anti-corrosion protective layer and a thermal insulation layer. The anti-corrosion protection layer is composed of an electrophoretic layer 4 and a heat-shrinkable film 5 , wherein the electrophoretic layer 4 is wrapped on the outer surface of the copper pipe, and the heat-shrinkable film 5 is wrapped on the outer surface of the electrophoretic layer 4 . The thermal insulation layer is composed of an inner thermal insulation layer 6 and an outer thermal insulation layer 7. The inner thermal insulation layer 6 is wrapped on the outer surface of the heat shrinkable film 5, and the inner thermal insulation layer 6 is made of water bridging polyethylene. Inner thermal insulation layer. The outer thermal insulation layer 7 wraps the outer surface of the ...

Abstract

The invention relates to an air conditioner connecting pipe. The air conditioner connecting pipe comprises a copper pipe, pipe joints and a protective layer coated the outer side of the copper pipe, wherein the protective layer comprises an anti-corrosive protection layer and a heat insulating layer, the anti-corrosive protection layer consists of an electrophoretic layer and a heat-shrinkable sleeve film; the electrophoretic layer coats the outside surface of the copper pipe, and the heat-shrinkable sleeve film coats the outside surface of the electrophoretic layer; the heat insulating layer consists of an inner heat insulating layer and an outer heat insulating layer, the inner heat insulating layer coats the outside surface of the heat-shrinkable sleeve film, and the outer heat insulating layer coats the outside surface of the inner heat insulating layer. The air conditioner connecting pipe has the advantages of good oxidation resistance and heat resistance.

Description

technical field [0001] The invention relates to an air conditioner connecting pipe. Background technique [0002] The air conditioner connecting pipe refers to the pipe connecting the outdoor unit and the indoor unit of the air conditioner, and its function is mainly to circulate the refrigerant between the indoor unit and the outdoor unit of the air conditioner. Most of the air-conditioning connecting pipes used at present have not treated the surface of the copper pipes, resulting in corrosion of the copper pipes after a period of use, which seriously shortens the service life of the connecting pipes. Even if some protective layers are wrapped on the surface of the copper pipes, one layer of these protective layers is made of rubber rubber material, and its temperature resistance can usually only reach 80°C-90°C. The resulting temperature is 110°C-120°C. Therefore, the above protective layer will have surface cracking and fragmentation after 2-3 years of use, seriously af...
