<p><P>PROBLEM TO BE SOLVED: To improve efficiency in manufacturing a heat-radiating fin according to a simple manufacturing process. <P>SOLUTION: In the manufacturing method of a heat radiating fin, the surface of a heat-radiating fin 4 is pressurized in stamping which is a plastic process, so that the surface is deformed plastically, to form one or more recesses 42. Since the recess 42 is formed by plastic deformation, a protruding part that has a reversal shape of the recess 42 is formed on the rear surface of the position corresponding to the recess 42. The heat-radiating fins 4 are stacked at constant intervals between them, by engaging a protruding part 43 and the recess 42 formed on the heat radiating fins 4 with each other for jointing. <P>COPYRIGHT: (C)2009,JPO&INPIT</p> |
