Abstract
The utility model provides a connecting pipe for connecting an indoor unit and an outdoor unit of an air conditioner, which comprises a stainless steel corrugated pipe and two sections of copper pipes, wherein the pipe body of the stainless steel corrugated pipe is formed by one or more spiral grains, and the two sections of copper pipes are respectively welded and connected to two ends of the stainless steel corrugated pipe; the junction between nonrust corrugated steel pipe and the copper pipe has one section stainless steel welded connection section, and stainless steel welded connection section and nonrust corrugated steel pipe formula as an organic whole do not set up the spiral ripple on the welded connection section, and stainless steel welded connection section and copper union coupling. The stainless steel corrugated pipe has the advantages of good flexibility, low price compared with a copper-aluminum pipe, good corrosion resistance, good heat preservation effect, good flexibility, good toughness and air tightness and convenience for extension.
Description
Technical Field
The utility model relates to the technical field of air conditioner parts, in particular to a connecting pipe for connecting an indoor unit and an outdoor unit of an air conditioner.
Background
At present, most connecting pipes used for connecting indoor units and outdoor units of air conditioners on the market are copper pipes and aluminum pipes, the price of the copper pipes used for connecting the air conditioners continuously rises due to the fact that the copper price continuously rises on the market in recent years, and the copper-aluminum connecting pipes are poor in corrosion resistance and short in service life, so that a metal pipe with relatively low price, good corrosion resistance and long service life is urgently needed to replace the copper-aluminum connecting pipes.
SUMMERY OF THE UTILITY MODEL
The utility model provides a connecting pipe of an indoor unit and an outdoor unit of an air conditioner, which has relatively low price and good corrosion resistance and aims to solve the problems of relatively high price of connecting copper pipes for connecting the indoor unit and the outdoor unit of the air conditioner and poor corrosion resistance of copper-aluminum connecting pipes in the prior art.
Therefore, the utility model adopts the following technical scheme that the connecting pipe for connecting the indoor unit and the outdoor unit of the air conditioner is characterized in that: the connecting pipe comprises a stainless steel corrugated pipe and two sections of copper pipes, the pipe body of the stainless steel corrugated pipe is composed of one or more spiral threads, and the two sections of copper pipes are respectively connected to two ends of the stainless steel corrugated pipe in a welding mode.
The stainless steel corrugated pipe and the copper pipe are connected through a stainless steel welding connection section, the stainless steel welding connection section and the stainless steel corrugated pipe are integrated, spiral ripples are not arranged on the welding connection section, and the stainless steel welding connection section is connected with the copper pipe.
A connecting pipe for connecting an indoor unit and an outdoor unit of an air conditioner is characterized in that: the connecting pipe comprises a stainless steel corrugated pipe, a pipe body of the stainless steel corrugated pipe is composed of one or more spiral grains, two ends of the stainless steel corrugated pipe are provided with stainless steel straight pipe sections which are integrally formed with the stainless steel corrugated pipe, and copper layers are cladded on the inner wall and/or the outer wall of each stainless steel straight pipe section.
The utility model can achieve the following beneficial effects: 1. the stainless steel corrugated pipe has good flexibility, does not need to change the original installation method, has low price compared with a copper-aluminum pipe, and has good corrosion resistance; in addition, the heat preservation effect of the stainless steel spiral corrugated pipe is good, and heat preservation transmission of air conditioner refrigeration media is facilitated. The stainless steel spiral corrugated pipe is adopted, so that the flexibility is better, and the stainless steel spiral corrugated pipe does not deform after being turned for many times. 2. The two ends of the stainless steel corrugated pipe are connected with the copper pipes, and the copper pipes are connected with the reserved interfaces of the equipment, so that the stainless steel corrugated pipe is good in toughness and air tightness, does not affect the normal use of an air conditioner, and is convenient to prolong.
