Aluminum foil paper is a product of aluminum foil for air conditioning radiators. The commonly used aluminum grades in aluminum foil with air conditioning fins are 1100 aluminum and 8011 aluminum. Common types of aluminum foil with fins in air conditioners include domestic air conditioners, central air conditioners, air conditioners for cars, air conditioners for computer rooms, air conditioners for trains and food refrigeration equipment. Because aluminum foil has good thermal conductivity, easy deformation and processing, light weight, low price, no pollution, etc., it has become the first choice for heat exchange fin material in air conditioners .

Aluminum foil used as a heat sink material has been around for more than 20 years. In recent years, with the development of the air conditioning industry, the production of fin foil has also developed rapidly. As production increases, the quality of aluminum foil for air conditioning also increases in product size, tempering of the alloy, mechanical properties and surface quality. According to different surface treatment methods, the aluminum foil for the fin material can be classified into an uncoated aluminum foil and a coated aluminum foil. Uncoated aluminum foil refers to ordinary aluminum foil, and the surface after lamination is not treated. The coated aluminum sheet refers to the ordinary aluminum sheet treated on the surface because the surface of the sheet coated with aluminum sheet is coated with a hydrophilic coating.

The air conditioner works by transferring heat between the air and the working fluid (coolant) inside the air conditioner. The air cannot transfer heat efficiently. To overcome the poor heat transfer characteristics of the air, a very large contact area with the air is used. The aluminum fins in the air conditioner are used to provide a surface area of tens of square meters in contact with the air, so that an adequate amount of heat can be transferred. If you look closely at the heat sink of the air conditioner, you will see the tubes pass through them. This is where the refrigerant is located. For reasons of cost, the fins are usually made of aluminum, as mentioned in the previous answer to the question.
