Connecting pipe and connecting pipe assembly with same

Abstract

The invention provides a connecting pipe and a connecting pipe assembly with the connecting pipe. The connecting pipe comprises a middle pipe section, a first transition section, a first connecting pipe, a second connecting pipe, and a connecting section, wherein the first transition section is connected between the two ends of the middle pipe section, and the horizontal included angle between the pipe wall of the first transition section and the middle pipe section is alpha (alpha is greater than 0 degree and less than or equal to 90 degrees); the first connecting pipe and the second connecting pipe are respectively connected with the first transition section; the connecting section is respectively connected with the first connecting pipe and the second connecting pipe; the pipe diameter of the first connecting pipe is equal to that of the second connecting pipe but different from the pipe diameter of the middle pipe section, and the first connecting pipe and the second connecting pipe are arranged asymmetrically relative to the middle pipe section; and the middle pipe section, the first transition section, the first connecting pipe, the second connecting pipe and the connecting section are integrated. In the invention, the connecting pipe assembly comprise a reducer pipe, a third connecting pipe and a fourth connecting pipe, wherein the third connecting pipe and the fourth connecting pipe are respectively connected with the two ends of the reducer pipe, the reducer pipe is the connection pipe, and the reducer pipe, the third connecting pipe and the fourth connecting pipe are integrated.

Description

technical field [0001] The invention relates to a connecting pipe and a connecting pipe assembly with the connecting pipe. Background technique [0002] In order to satisfy the connection between the indoor unit and the outdoor unit system of the split air conditioner, corrugated pipe fittings are usually used for connection. The refrigerant circulates between the outdoor unit and the indoor unit, requiring well-sealed connecting pipes. Due to the influence of installation location and use space, corrugated pipe fittings are usually made of pipes with different diameters connected by welding. During welding, problems such as welding pores and virtual welding often occur, resulting in leakage of system refrigerant and seriously affecting the performance of the unit. . [0003] Secondly, the structure of the existing corrugated pipe fittings is symmetrical, and some places that do not need to be processed must be processed, so that the processing cost is relatively high. ...
