Abstract

The invention relates to a air condition connecting pipe connecting inside and outside machines for coolant transmission and production method thereof, which belongs to air-conditioning accessory and manufacturing technique field. The connecting pipe includes brass tubes on both ends and cup jointed connecting nuts, characterized in that brass tubes on both ends are jointed integrally by a steel pipe welded by steel strips, the steel pipe outer sleeve is provided with corrosion-proof protective layer and insulating sleeve, the brass tubes and connection ends of the steel pipe are provided with enlarging ports, both ends of the steel pipe are inserted to the enlarging ports of the brass tubes, space between outer wall of the steel pipe and inner wall of the brass tube enlarging ports is filled with braze welding material. Manufacturing cost of the air condition connecting pipe can be effectively reduced by the invention.

Description

technical field [0001] The invention relates to an air conditioner connecting pipe for connecting internal and external units of an air conditioner for refrigerant transfer and a production method thereof, belonging to the technical field of air conditioner accessories and their manufacture. technical background [0002] Because copper itself has good anti-corrosion and anti-rust properties, copper is widely used in the manufacture of refrigeration and heating industry products such as air conditioners that require high anti-rust and anti-corrosion properties. However, as the price of copper continues to rise, the use of copper to manufacture air-conditioning accessories will lead to a continuous increase in the cost of air-conditioning manufacturing. Therefore, someone has proposed a technical solution to replace copper pipes with aluminum pipes in order to reduce the production cost of air-conditioning. For example, a patent application called air conditioner connecting pi...
