Connecting pipe assembly, connecting pipe, air conditioner and manufacturing method

Abstract

The invention discloses a connecting pipe assembly, a connecting pipe, an air conditioner and a manufacturing method, the connecting pipe assembly comprises a main pipe, a first pipe fitting, a second pipe fitting, a third pipe fitting and a fourth pipe fitting, the main pipe is made of an aluminum material, the first pipe fitting and the third pipe fitting are made of a steel material, and the second pipe fitting and the fourth pipe fitting are made of a copper material; a concave-convex part is arranged on one of the matching parts of the first pipe fitting and the second pipe fitting, and a concave-convex part is arranged on the inner wall of a fourth steel joint part of the third pipe fitting or a concave-convex part is arranged on the outer wall of a second copper joint part of the fourth pipe fitting, so that the first pipe fitting and the second pipe fitting are fixed after being assembled; the third pipe fitting and the fourth pipe fitting can be relatively simple and convenient to fix and assemble after being assembled, and the connecting pipe assembly can be conveniently connected with a copper pipe in a system.

Description

【Technical field】 [0001] The invention relates to a key linking technology, in particular to a connecting pipe assembly, a connecting pipe, an air conditioner and a manufacturing method. 【Background technique】 [0002] Some systems need to use connecting pipe components, such as air conditioning systems. Currently, the connecting pipe fittings for the internal and external units of air conditioners in the market are made of red copper. The same type of material is conducive to welding, and the connection is relatively convenient. The general air-conditioning system uses copper pipes for connection, but the processing of copper pipe-type connecting pipe components may require surface treatment such as pickling, which has a certain impact on environmental protection. [Content of the invention] [0003] In order to provide a new connecting pipe assembly, the main body of which can be made of stainless steel and can be welded with the copper pipes of the internal and external ...

AI Technical Summary

Problems solved by technology

[0002] Some systems need to use connecting pipe components such as air-conditioning systems. The connecting pipe fittings of the internal and external air conditioners used in the market are all made of red copper, and the outer sleeve is covered with an insulating sleeve. The ports are made of brass nuts. The same type of material is conducive to welding, and the connection is relatively convenient. Generally, copper pipes are used for connection in air-conditioning systems, but the processing of copper pipe connecting pipe components may require surface treatment such as pickling, which has a certain impact on environmental protection.
