Why Is Hydrophilic Aluminum Foil Used for Air Conditioner

The difference between hydrophilic aluminum foil and ordinary aircon aluminum foil is that it has been surface treated - it has an additional hydrophilic layer. Since aluminum foil coated with a hydrophilic coating, its heat exchange performance is also better.

The surface of hydrophilic aluminum foil has a strong affinity for water. Condensed water spreads quickly on the fins and is not easy to form "water bridges". Therefore, its ventilation effect is good when the air conditioner is running.

The air conditioner aluminum foils are commonly used in a variety of automotive radiators, HVAC, insulation panels and air conditioning applications. 1100, 1145, 3003 and 8011 aluminum alloys are all good alloy choices due to aluminum's corrosion resistance. The colors of aircon aluminum foils are also different. Blue and gold aluminum foils are more popular.

Air conditioner aluminum foil generally chooses 3003 aluminum foil. It mainly needs to have good formability, few metallurgical defects and small anisotropy. It also requires high strength, good ductility, uniform thickness and good straightness.

The amount of aluminum foil used in air conditioners varies greatly depending on the model and power of the air conditioner. Making thinner aluminum foil can reduce the use of aluminum and reduce the cost of air conditioner radiators with the same heat exchange area.

The specific type of aluminum foil used to process heat exchange fins needs to be customized according to actual application and functional requirements. For example, whether hydrophilic or hydrophobic processes are required, and whether anti-corrosion processes are required, all need to be customized according to actual needs.

The production process of hydrophilic aluminum foil requires the aluminum ac coil to have a good shape, which is a prerequisite for the production of coated aluminum foil. The unit for measuring plate shape indicators is I. Generally, the plate shape requirements of coating production equipment are within 20-40I. If it is greater than this value, a tension straightening system needs to be added in front of the coating equipment.

Generally, the aluminum strip running route of coating equipment is long, and there are many processing steps and guide rollers. Therefore, if the tension straightening system is not equipped, once the plate shape is not good, it will easily break during operation, resulting in the failure of production.
