Embodiment Construction

[0024] The components represented by the numbers in the drawings are as follows: anti-corrosion rubber plug 101, copper pipe 102, steel pipe 103, heat shrinkable film 201, powder spray layer 202, electrophoretic layer 203, copper nut 301, sealing plug 302, heat preservation sleeve 303 .

[0025] The present invention will be further described below through specific embodiments and in conjunction with the accompanying drawings.

[0026] see figure 1 , the connecting pipe of the air conditioner of the present invention is formed by welding the copper pipe 102 and the steel pipe 103, and the two ends of the steel pipe 103 are welded with the copper pipe 102. During processing, one end of the steel pipe 103 is inserted into the copper pipe 102 after being reduced in diameter and fixed by welding. , it must be ensured that the steel pipe is shrunk and then inserted into the copper pipe. The insertion depth is 10mm to 20mm. The welding fusion length of the steel pipe and the copper...

Abstract

The invention relates to an air conditioner connecting pipe, which is respectively connected with refrigerating system pipelines of an indoor machine and an outdoor machine of an air conditioner and is formed from a steel pipe and copper pipes by welding; and the two ends of the steel pipe are respectively welded to one copper pipe. In the air conditioner connecting pipe manufactured from the steel pipe and the copper pipes by welding, has simple structure, is easy to implement. By the invention, the requirements of refrigerating equipment on physicochemical performances of a connecting piece such as high strength and corrosion resistance and the like can be met, and the material cost and the manufacturing cost of the connecting pipe can be greatly reduced, wherein the price of materials is only about one tenth of that of the copper pipes, therefore, the market competitiveness of the air conditioner connecting pipe is improved.

Description

technical field [0001] The invention relates to the field of air conditioners, more specifically, to an air conditioner connecting pipe and a processing method. Background technique [0002] The air conditioner connecting pipe of the present invention refers to the pipe connecting the outdoor unit and the indoor unit of the air conditioner, and its function is mainly a channel for refrigerant circulation between the air conditioner indoor unit and the outdoor unit. In the past, such pipes were made of Copper pipe manufacturing, its production technology is relatively mature, but the connecting pipes of indoor and outdoor units made of copper pipes need to consume a large amount of copper, with an average of 2 to 3 kg of copper for each connecting pipe of indoor and outdoor units. In recent years, the price of copper in the international market has continued to rise, resulting in The production cost of air conditioners is increasing rapidly. It has brought tremendous pressur...
