Talking about the development of aluminum fin-stock

The raw material of aluminum foil fin-stock is a special material used to manufacture heat exchanger fin-stock for air conditioners. The raw material of fin-stock used in the early days is ordinary aluminum foil, which we call bright foil, white foil, silver foil or plain foil. In order to improve the corrosion resistance of this aluminum foil, before forming the hydrophilic aluminum foil, a layer of corrosion-resistant inorganic coating and a layer of hydrophilic organic coating is applied.

Hydrophilic aluminum foil accounts for 60% of the total fin stock, and its utilization rate will be further increased. There is also a waterproof aluminum foil, which provides a hydrophobic effect on the surface of the heat sink to prevent condensation of condensate. The technology to improve the surface defrosting performance of hydrophobic aluminum foil needs further research, and the actual production is very few. Because the materials used must be non-toxic, harmless, environmentally friendly and energy-saving. Our company has done experiments on the side panels of the refrigerator, and the use of hydrophobic aluminum foil can effectively prolong the frosting time on the inner wall of the refrigerator.

Compared with the ordinary hydrophilic aluminum foil, the hydrophobic aluminum foil has no frost residue after twenty-four hours, while the ordinary hydrophilic aluminum foil has a thick layer of frost.

The general thickness of the air conditioner fin blank are 0.1mm to 0.15mm. With the development of technology, the condenser fin-stock had a trend of further thinning. Japan’s leading product has a thickness of 0.09mm, while in my country it is 0.094mm. Aluminum foil should have good formability in an extremely thin state, and its structure and performance must be uniform. This requires the aluminum foil to maintain sufficient strength, good ductility, uniform thickness and good flatness while being thinner. The specifications and alloys of the fin-stock are relatively simple and suitable for mass production, but the market is seasonal.

For general aluminum foil fin manufacturers, it is difficult to solve the contradiction between shortage in peak season and almost no demand in off season. Xianxing Aluminum focuses on the development of air-conditioning aluminum foil fin-stock, there is no difference between low and peak seasons, as long as you need it, please feel free to click on the message box on the right to get a free quote!
