Coated aluminum fins for heat exchangers is used as a heat conduction fin material for air conditioning heat exchangers, with the advantages of small density, good thermal conductivity, easy processing, no odor, environmental friendliness, and low price. Pre coated aluminum fin stock for conditioning adopts aluminum alloy 1100, 3003, 8011, temper O, H22, H24, H26, thickness 0.09-0.2mm, width 100-1300mm, core inner diameter 76mm/152mm. Air conditioning aluminium foil is used in air conditioning heat exchange equipment, and it is widely used due to its good plate shape, good coating performance, high coating adhesion, good hydrophilicity and good corrosion resistance.
Air conditioning heat exchanger dedicated hydrophilic coated aluminum foil. Coated aluminum fins for heat exchangers is made of degreased (rinsed) ordinary industrial aluminum foil, coated with base film and hydrophilic film. The hydrophilic aluminum foil has a three-layer structure. The three-layer structure consists of one layer of aluminum foil, one layer of hydrophilic base film (double-sided), and one layer of hydrophilic surface film (double-sided). Using this hydrophilic aluminum fin for heat exchanger as the fins of the air conditioning heat exchanger can change the contact angle of condensation water droplets on the surface of the fins, eliminate the “water bridge” phenomenon in the air conditioning heat exchanger, reduce the occurrence of white powder phenomenon, increase the cooling capacity of the air conditioner by 7-15%, and extend the effective service life of the heat exchanger.
Coated aluminum fins for heat exchangers special coating is an organic water-based coating formulated by blending thermosetting high molecular resin and water-soluble modified resin, which is suitable for roll coating method used in strip production line, as a closed anti-corrosion and hydrophilic treatment on the surface of aluminum foil in air conditioning heat exchangers. This pre-coated aluminum fin stock for heat exchangers has excellent coating performance and excellent construction performance.
