Air conditioning industry fin stock application analysis

Edit:Mingtai Date: 2019-08-13 11:14
Fin stock are classified into plain foil and hydrophilic foil depending on their production process and performance. The hydrophilic foil is an anti-corrosive inorganic coating and a hydrophilic organic coating on the surface of the aluminum foil, and has anti-corrosion, anti-mold, no odor and the like, and the cooling efficiency is improved by about 5 compared with the plain foil. % is a more ideal air conditioning heat sink material. Hydrophilic foil accounts for more than 80% of the total stock of fins. Inverter air conditioners and export air conditioners use hydrophilic foils, while domestic low-end air conditioners, window machines and automobile air conditioners use plain foil.
The amount of fin stock used varies greatly depending on the model and power size. In recent years, the thickness of fin stock has been reduced from 0.12mm to 0.15mm to 0.09mm~0.11mm. At the same time, with the development of air conditioners in the direction of high efficiency, energy saving and light weight, the demand for fin stock has been improved year on year. A significant reduction in the average amount of fin stock has been reduced from 5 kg per litre to 3.5 kg per litter. In the past two years, the ratio of high-power air conditioners has increased, and the amount of aluminum foil per air conditioner has reached 7-10 kg. From this point of view, the average amount of aluminum foil used in each air conditioner is still above 4 kg.
With the increase in per capita income and the acceleration of urbanization, China's air-conditioning consumption has a large room for growth, which will strongly promote the demand for aluminum foil. In the context of China becoming a global air-conditioning production base, the fin stock market is facing tremendous room for development.
