摘要： Provided is a precoated fin material for heat exchangers that allows the construction of a fin structure in which frost formation at the time of heater operation can be prevented to the extent possible, and under such a condition that condensation is liable to occur on a fin surface, a water droplet of condensed water can be quickly removed by bringing the water droplet into contact with a hydrophilic film, and as a result, a favorable heat exchange function can be maintained without any increase in ventilation resistance. Also provided is a heat exchanger including such fin structure. The precoated fin material for heat exchangers includes: a fin substrate formed of an aluminum plate material; a crosslinked hydrophobic film having a frost formation-suppressing effect, the crosslinked hydrophobic film being formed on one surface of the fin substrate and being formed of an aqueous hydrophobic coating composition containing a resin (A) having a fluorine atom-containing group, a quaternary ammonium salt group-containing modified epoxy resin (B), and an amino resin (C) at predetermined ratios; and a hydrophilic film having a condensed water-removing effect, the hydrophilic film being formed on another surface of the fin substrate. The heat exchanger includes a fin structure in which a hydrophobic surface having a frost formation-suppressing effect and a hydrophilic surface having a condensed water-removing effect are opposite to each other.

摘要： This invention relates to water-based hydrophilic coatings suitable for giving hydrophilicity primarily to the surface of aluminum and to a process for manufacturing precoated fin materials for heat exchangers with use of said coatings. The coatings are composed of colloidal silica with a dispersed particle diameter of 5 to 100 nm, water-soluble polymers containing at least carboxylic acid polymers, anionic surfactants and water; the colloidal silica and the water-soluble polymers are present at a weight ratio of 30:70 to 70:30 on a solid basis in a combined content of 4 to 20% by weight, the content of carboxyl group in the carboxylic acid polymers contained in the water-soluble polymers is 20 to 63% by weight, the anionic surfactants are alkali salts of sulfosuccinic acid monoalkyl esters with alkyl groups containing 1 to 18 carbon atoms and present in an amount of 5 to 20% by weight of the combined solid content of the colloidal silica and the water-soluble polymers, and the pH is 1 to 5 as a whole. The process for manufacturing precoated fin materials for heat exchangers comprises applying the water-based hydrophilic coatings to the surface of aluminum fin materials to a solid weight of 0.3 to 1.5 g/m.sup.2 and drying under heat.
