Air conditioner connecting pipe with protective structure

Abstract

The invention relates to an air conditioner connecting pipe with a protective structure. 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 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; a plug is arranged at each pipe mouth of the copper pipe, one end of each plug is matched with the copper pipe in a plugging manner, and the plugs are made from rubber and are conical. The air conditioner connecting pipe has oxidation resistance, and corrosion or blockage to the pipe caused by dust or harmful gases can be prevented.

Description

technical field [0001] The invention relates to an air conditioner connecting pipe with a protective structure. 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 currently used air-conditioning connecting pipes with protective structures 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 crackin...

AI Technical Summary

Problems solved by technology

At present, most of the air-conditioning connecting pipes with protective structure are not treated on 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.

In addition, the connecting pipe is generally exposed before use. During the process of transportation or installation, dust and other harmful substances are easy to penetrate into the pipe, causing corrosion to the pipe, and even clogging in severe cases. Therefore, it is necessary to protect the connecting pipe
