Different-diameter joint-free corrugated connecting pipe and manufacturing method thereof

Abstract

The invention discloses a different-diameter joint-free corrugated connecting pipe and a manufacturing method thereof. The different-diameter joint-free corrugated connecting pipe is of an integrated structure, and sequentially comprises a first port (1), a first corrugated pipe (2), an unthreaded pipe (3), a second corrugated pipe (4) and a second port (5). The outer diameter of the unthreaded pipe (3) is smaller than that of each of the first corrugated pipe (2) and the second corrugated pipe (4). The wall thickness of the unthreaded pipe (3) is larger than that of each of the first corrugated pipe (2) and the second corrugated pipe (4). The different-diameter joint-free corrugated connecting pipe is of the integrated structure and free of leakage, and the pipe wall of an unthreaded pipe section is thicker than the pipe walls of corrugated pipe sections, so that the different-diameter joint-free corrugated connecting pipe is less prone to bending and deforming during mounting, and normal circulation of media in the pipe can be ensured.

Description

technical field [0001] The invention relates to the field of copper pipes, in particular to a jointless corrugated connection pipe with different diameters and a manufacturing method thereof. Background technique [0002] The split type air conditioner is a very popular household appliance. The indoor unit and the outdoor unit are connected systematically through a connecting pipe. The typical structure of the connecting pipe in the prior art is an equal-diameter pipe, and its pipe diameter is the same as that of the equipped compressor to transport the refrigerant medium. tube the same. Limited by the structure of the compressor, the connecting pipes in the prior art have thinner pipe diameters and low structural strength. During the wiring connection, especially the section through the wall is easily bent and deformed to reduce the circulation of the refrigerant medium in the pipe. At present, there is already a different-diameter connecting pipe installed on the split ai...

Problems solved by technology

[0003] The first purpose of the present invention is to solve the problem that the diameter of the connecting pipe in the current split air conditioner is bent and deformed to reduce the circulation of the refrigerant medium in the pipe. 1. The first bellows 2, the light pipe 3, the second bellows 4 and the second port 5, the first port 1, the first bellows 2, the light pipe 3, the second bellows 4 and the second port 5 An integral structure; the outer diameter of the light pipe 3 is smaller than the outer diameters of the first bellows 2 and the second bellows 4, and the wall thickness of the light pipe 3 is greater than the wall thickness of the first bellows 2 and the second bellows 4; The first port 1 is formed by narrowing the outer end of the first bellows 2, and the second port 5 is formed by narrowing the outer end of the second bellows 4
