Air conditioning aluminum foil, also known as aluminum foil fins, is a special material for manufacturing heat exchanger fins for air conditioners. The air conditioner foil used in the early days was ordinary aluminum foil. In order to improve the surface properties of the ordinary aluminum foil, it is coated with anti-corrosion coating and hydrophilic coating before forming to form a hydrophilic aluminum foil, which is widely used in household industrial air conditioners, refrigerators, automobile air conditioners and other refrigeration equipment. In addition, there is another kind of hydrophobic aluminum foil, which makes the surface of the fins have a hydrophobic function and prevents condensation from sticking, it is mainly used in dryers to improve heating efficiency. Air conditioner aluminum foil is used as heat-conducting fin material for air-conditioning heat exchangers. It has the advantages of low density, good thermal conductivity, easy processing, odorless, environmental protection and low price. Hydrophilic aluminum foil can be surface-coated, usually blue and gold-plated. The main aluminum foils for air conditioning are: 8006 hydrophilic aluminum foil, 8011 hydrophilic aluminum foil, 3102 hydrophilic aluminum foil, 1100 hydrophilic aluminum foil, etc.
8011 Hydrophilic aluminum foil and 8006 hydrophilic aluminum foil are mainly used in the production of heat exchanger fins, such as condensers and evaporators of air conditioner, refrigerator, automotive air-conditioning, etc. 8011 aluminum foil is added with Al-Fe-Si elements. Its performance is better than pure aluminum foil. Aluminum foil fin heat exchangers mostly use 8011 aluminum alloy. Because of its outstanding performance advantages and high cost performance, 8011 air conditioning aluminum foil is very popular among market users. The commonly used tempers are 8011-O hydrophilic aluminum foil and 8011-H22 hydrophilic aluminum foil. The iron content of 8006 hydrophilic aluminum foil is higher than 8011 hydrophilic aluminum foil, and the performance is slightly better. 8006 aluminum foil has a higher tensile strength than 8011 aluminum foil, which can reach 125-135; also, the cup convexity and elongation of 8006 aluminum foil are higher than 8011 aluminum foil.
3102 Aluminum foil has the characteristics of high strength, oxidation resistance, corrosion resistance, and not easy to deform. It is an excellent product for making aluminum foil for air conditioners such as radiators, heat exchangers. 3102 Air-conditioning aluminum foil is used as heat-conducting fin material for air-conditioning heat exchangers. It has the advantages of low density, good thermal conductivity, easy processing, odorless, environmentally friendly and low price. 3102 Hydrophilic aluminum foil is widely used in household air conditioners, refrigeration cabinets and other refrigeration equipment, automobile air conditioners and automobile water tanks.
