The
aluminum foil for air conditioner is mainly divided into two types: plain
aluminum foil and hydrophilic
aluminium foil due to their different performance. Plain
aluminum foil refers to the rolled and annealed
aluminum foil without any surface treatment, and is mainly used for low-grade split air conditioner outdoor units and window-type air conditioner.In recent years, with the improving requirements for energy-saving, environmental protection and corrosion and bacteria resistance, the plain
aluminum foil gradually can’t satisfy the need. That’s why more and more air conditioner manufacturers choose hydrophilic
aluminum foil.The surface of the hydrophilic foil has a strong hydrophilicity. The water droplets condensed on the radiator are easy to spread and flow down, avoiding affecting the ventilation effect of the radiator, so that the heat exchange efficiency is increased by 5%.In addition, the hydrophilic coated foil is of strong corrosion resistance, great bacteria resistance and no odor, which is mainly used for high-end air conditioners. Hydrophilic
aluminum foil is to do hydrophilic treatment for the
aluminum foil, which is coated with an anti-corrosion coating and a hydrophilic coating and is dried in a drying furnace.Because the surface is coated with a hydrophilic layer, the condensed water will quickly spread on the hydrophilic
aluminum foil and will not condense into water beads, accelerating the cooling and heating speed and effectively avoiding the noise of air flow caused by the obstruction of the condensed water.The main advantages of hydrophilic aluminum fin stock:1. Excellent hydrophilicity and corrosion resistance.2. Good formability and no abrasion to the mold.3. Extremely strong resistance to stamping oil, solvent and heat.4. The air flow resistance is small, and the heat exchange rate can generally be increased by 10%-15%.
