With the development of technology, have air conditioning foil further thinning of the trend in the state extremely thin, aluminum foil to have good formability. Their organization and performance must be even, metallurgy less vulnerable, small anisotropic, also requires high strength, good ductility and even thickness, good straightness.
Hydrophilic aluminum foil is treated with a special process by coating a hydrophilic layer on the surface thereof, then condensed water will rapidly spread on the hydrophilic aluminum foil, and thus it will not condense into water droplets, and increase heat exchange area, speeding up the cooling and heating speed, and therefore effectively avoiding the noise caused by the condensed water obstructing the air flow.
