Hydrophilic aluminum foil is a kind of aluminum foil that has been treated with hydrophilicity. Through a special process, a hydrophilic layer is coated on its surface. The condensed water will quickly disperse on the hydrophilic aluminum foil and will not condense into water droplets, thereby increasing the heat exchange area, speeding up the cooling and heating speed, and effectively avoiding the noise caused by condensed water blocking the air flow.

Hydrophilic aluminum foil is the main raw material for household air conditioner heat exchangers and has a great impact on the efficiency of air conditioners. If the raw material of the heat exchanger is hydrophilic aluminum foil, the refrigeration efficiency can be increased by 5%. It also has the functions of anti-corrosion and anti-mildew, no odor, and will not cause water droplets to accumulate and block the heat exchange.
