    摘要： Provided is a heat exchanger including a heat exchange fin 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 continuously obtained without any increase in ventilation resistance. The heat exchanger includes a heat exchange fin made of an aluminum plate material that has a crosslinked hydrophobic film having a frost formation-suppressing effect and a hydrophilic film, in which: an area occupied by the crosslinked hydrophobic film in a square area measuring 10 mm by 10 mm at an arbitrary position on a surface of the heat exchange fin is 20 to 80%; and the crosslinked hydrophobic film is 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) in which the solid content of the resin (A) is 1 to 30 parts by mass with respect to 100 parts by mass of the total of the solid contents of the resin (B) and the resin (C).

    摘要： A corrugated-fin heat exchanger is constructed by arranging a plurality of flat heat exchange tubes parallel to each other in a horizontal direction between a pair of opposing header pipes, joining, at a position between the plurality of flat heat exchange tubes, corrugated fins formed by alternately repeating peak folding and valley folding portions, and forming water flow passages from lug pieces that are obtained by obliquely cutting and raising flange portions extending along end portions of each of the plurality of flat heat exchange tubes (3) in a width direction thereof. A pitch (P) of each of the corrugated fins between a peak and a valley thereof, a width (L) of each of the lug pieces in a vertical direction thereof, and a thickness (T) of the each of the plurality of flat heat exchange tubes have a relationship of P×2≧L≧T.

    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.
