Abstract: PURPOSE:To improve heat exchanging efficiency by a method wherein a heat transfer pipe and a fine wire fin are combined by means of melted and solidified substance of a metallic coat which is plated on a surface of either one of the heat transfer pipe and the fine wire fin. CONSTITUTION:A heat transfer pipe 11 is preparatorily applied with a plating treatment in a non-electrolytic Ni plating solution to form a metallic coat 13 of nickel on an outer peripheral surface of the heat transfer pipe 11.

Then, the Ni-plated coat 13 melts down and gathers at a contacting part with the fine wire fins 12a and 12b by its surface tension, its wetness and the like to form a fillet. As the fine wire fins 12a and 12b and the heat transfer pipe 11 are combined with each other by the plating material which has been melted and solidified, a thermal contact can be realized without fail. Accordingly, a heat transfer between the heat transfer pipe 11 and the fine wire fins 12a and 12b can be promoted, and thereby heat exchanging efficiency can be improved.
