Description
Technical Field
The utility model relates to an air conditioner refrigeration technology field, in particular to anticorrosive refrigerant pipe of idle call combination formula.
Background
With the rapid development of economy and the continuous improvement of living standard of people, the consumption of people gradually changes from living consumption to enjoying consumption. The emergence of air conditioners meets the requirements of people on living comfort. The air conditioner consists of indoor unit and outdoor unit and has the function of regulating the indoor air temperature.
The air conditioner connecting pipe is a pipe section for connecting the indoor unit and the outdoor unit of the air conditioner, and mainly serves as a channel for circulating the refrigerant between the indoor unit and the outdoor unit of the air conditioner. At present, most of the indoor units and the outdoor units are connected by copper refrigerating pipes, and the copper resource of China can not meet the requirements of social development and economic construction, so that the search for a material with similar performance, lower price and rich reserve to replace copper becomes one of the actual problems which are urgently needed to be solved in the current refrigerating industry. In addition, the quality and performance of the refrigeration pipe have an extremely important influence on ensuring the refrigeration effect, the service life and the cost of other refrigeration products such as an air conditioner and the like, so that the improvement of the quality of the refrigeration pipe is particularly important.
At present, in order to reduce cost, some enterprises generally adopt an aluminum pipe to replace a part of copper-aluminum connecting pipes of a copper pipe body structure, and the copper-aluminum connecting pipes are pipe fittings obtained by welding copper pipes and aluminum pipes. However, since copper and aluminum are different materials, electrochemical corrosion is more likely to occur in copper-aluminum combinations than in the same material. In order to solve the technical problem of corrosion, general enterprises coat anticorrosive coatings on the outer surfaces of connecting pipes, but the anticorrosive processes in the market are different, and when the thickness of the coating does not reach the standard thickness or the coating is not uniform and the coating is scratched in the transportation and construction processes, the coating which originally has electrochemical protection is prematurely damaged and exposed out of the pipe body, so that the corrosion is accelerated.
For example, patent CN 101955356U discloses a stainless steel corrugated pipe for air conditioner, which includes a stainless steel pipe body capable of being passed through with refrigerant, wherein two ends of the stainless steel pipe body are flat and straight pipe wall sections, and the pipe wall of the stainless steel pipe body in the middle is a plurality of annular corrugated pipe wall sections and a plurality of flat and straight pipe wall sections; a flat straight pipe wall section is arranged between every two annular corrugated pipe wall sections, and the middle parts of the stainless steel pipe body are formed by the plurality of annular corrugated pipe wall sections and the plurality of flat pipe wall sections at intervals. Although this patent discloses flexible bellows, it is only to stainless steel, and first stainless steel's ductility is not good and weight is great, easy rupture during bending, or the gas leakage phenomenon appears in the later stage use, and the gas tightness can not be guaranteed. Secondly, a protection device is not arranged between the flat pipe and the corrugated pipe, the joint between the flat pipe and the corrugated pipe is extremely easy to corrode, the air leakage condition is caused, the air tightness is poor, and the service life is short.
For another example, patent CN 108935590U discloses a corrugated connecting pipe, which includes a middle pipe and a corrugated pipe disposed on one side or both sides of the middle pipe, wherein the corrugated pipe includes a corrugated section, a welding end connected to the middle pipe, and a service connecting end opposite to the welding end, and the middle pipe and the welding end of the corrugated pipe are connected by welding. The bellows that above-mentioned patent provided, although adopted different materials, the intermediate pipe is aluminium promptly, and the end pipe is copper, and the copper pipe is the bellows, has solved difficult bending and costly technical problem. On the other hand, a welding connection mode is adopted, the integral consistency of the corrugated pipe is ensured, and the leakage of a condensing agent is avoided. However, no preservation measures are taken. Firstly, the middle pipe is aluminum, and the aluminum pipe is exposed in the atmosphere, very easily reacts with sodium ions in the atmosphere, leads to the emergence of corrosion phenomenon. Secondly, because copper and aluminum belong to different materials, when the copper and the aluminum are in contact with each other, the metal electrode potential difference exists because of different metal physical characteristics, and because humid air forms similar electrolyte, the metal forms similar corrosion batteries in the similar electrolyte due to the difference, the metal with higher potential is protected by electrochemistry, the corrosion rate is slower, and the metal with lower potential is accelerated to corrode. That is to say, there is electrochemical corrosion in the copper aluminium welded joint department of this patent, compares with same material, and the copper aluminium combination is changeed and is taken place the corruption for the airtight performance of air conditioner connecting pipe reduces, seriously influences the refrigeration effect of air conditioner, and life shortens greatly simultaneously.

The corrugated pipe section 2 can be bent according to actual working conditions during installation, so that the installation difficulty is reduced, the installation quality is ensured, and the installation efficiency is improved. One end of the corrugated pipe section 2 is provided with a mounting end 3 connected with an air conditioner, and the other end is connected with the end part of the straight pipe section 1 in a welding way. Wherein, the straight pipe section 1 and the corrugated pipe section 2 are fixedly connected in a welding mode, and the joint has high strength and is not easy to crack. And the inner diameters of the straight pipe section 1 and the corrugated pipe section 2 are the same or close to each other, so that the refrigerant can flow rapidly and stably, and the refrigeration effect is improved. In this embodiment, the corrugated pipe section 2 is made of red copper, and the straight pipe section 1 is made of aluminum.
