<p><P>PROBLEM TO BE SOLVED: To provide an aluminum fin having superior anti-frosting performance even in a cross fin tube type heat exchanger having a narrow fin interval (fin interval of 2 mm or less). <P>SOLUTION: This aluminum fin 1 for the heat exchanger is constituted by a base 10 made of aluminum, and one or more coating films 2 formed on a surface of the base 10. A component included in the outermost coating film 2 among the coating film, satisfies A+B≥95%, A≥10%, and B≥10% by solid content mass percent, when a fluorine resin including an perfluoroalkyl group is A, and the total of either or both of urethane resin and epoxy resin is B. The outermost coating film 2 preferably has a water droplet contact angle of 90-150°. <P>COPYRIGHT: (C)2011,JPO&INPIT</p> |
