Hydrophilic aluminum foil is a kind of hydrophilic treated aluminum foil. Through a special process, the hydrophilic layer will have convection on its surface. If the condensate on the hydrophilic aluminum foil will diffuse rapidly, it will not condense into water droplets and will not increase replacement. Hot area, thereby speeding up the cooling and heating rate, and also effectively avoiding airflow noise caused by air condensation.
2.Uages of Hydrophilic aluminium foil
Hydrophilic aluminum foil is the main raw material for household air-conditioning heat exchangers. It has a great influence on the efficiency of the air conditioner. If the raw material of the heat exchanger is hydrophilic aluminum foil, the cooling efficiency can be improved by 5%, and it also has the functions of anti-corrosion, anti-mildew, and odorless, and will not cause the accumulation of water droplets to affect heat transfer. Because there are no water droplets, the noise caused by vibration is correspondingly reduced; the air-conditioning powder is prevented from being blown into the room, causing adverse effects on the human body, and meeting environmental protection requirements. Hydrophilic aluminum foil for air-conditioning should comply with YS/T95.2-2001.
