Hydrophilic aluminium foil is hydrophilic treatment of aluminium foil. Through special process treatment, a layer of hydrophilic layer is coated on its surface. Condensate water will disperse quickly on the hydrophilic aluminium foil, and will not condense into water droplets, increase the heat exchange area, accelerate the refrigeration heating speed, and effectively avoid the noise caused by condensate water hindering air flow.
Hydrophilic aluminium foil is the main raw material of heat exchanger of household air conditioner, which has a great influence on the efficiency of air conditioner. If the raw material of the heat exchanger is hydrophilic aluminium foil, the refrigeration efficiency can be increased by 5%. It also has the function of anti-corrosion and anti-mildew, no odor, and will not cause the accumulation and blockage of water droplets to affect the heat transfer. The national standard for aluminium sheet and strip (GB/T 3880-2006) is applicable to the unified standard for aluminium alloy sheet and strip materials. Aluminum foil is defined in GB/T3880-2006 as having a thickness of less than 0.2 mm.
