Problems solved by technology

[0005] When the air conditioner is turned on in winter, because the internal mechanism of the air conditioner is heated, the external unit becomes cooling. When the heat reaches a certain temperature, the condenser of the external unit will defrost. When the machine is working, the four-way valve is reversing, and after reversing, heat the external machine to melt the frost of the external machine, and steam and water will be generated. At this time, neither the simple hydrophobic air-conditioning foil nor the hydrophilic air-conditioning foil can effectively remove steam and water

Abstract

The invention discloses an aluminum air conditioner foil with breathability and a preparation method thereof, the aluminum foil is made from lithium titanate crystal whiskers and 6061 aluminium alloy, two sides of the aluminum foil with breathability are respectively compounded with a hydrophilic film and a hydrophobic film, an air conditioner foil product obtained through the material and the method has tensile strength being up to 160 to 180Mpa, and ductility being greater than 18 percent. Meanwhile, the air conditioner foil product has good hydrophilicity and hydrophobicity, can greatly improve heat exchange efficiency of an air conditioner, and prevent the air conditioner from frosting.

Description

technical field [0001] The invention relates to an aluminum alloy material and a manufacturing process thereof. More specifically, the present invention relates to an air-permeable aluminum air-conditioning foil applied to an air-conditioning heat exchange sheet and a preparation method thereof. Background technique [0002] The aluminum alloy materials currently used to produce air-conditioning foils are generally 8011 and 1030B alloys. The use of 8011 alloy to produce air-conditioning foil has the advantages of good elongation and high flanging height, but this alloy is soft, the speed is slow in the punching process, and the production efficiency is low; for 1030B alloy, due to its good rigidity, It can adapt to high-speed punching machines and improve production efficiency. However, due to the problem of its own alloy ratio, the alloy product has a low flanging height during the punching process and is easy to crack. Therefore, the existing air-conditioning foil materi...
