Abstract

PURPOSE: To improve efficiency and prevent thermal deformation by forming a constricted portion with acute angles by applying a pinching pressure at a jointing portion of a jointing member under a normal temperature and press-jointing a member to be jointed, inserted into the jointing portion, further, tightening the constricted portion toward each other.
CONSTITUTION: A plate 3 for making a fin is preformed by pressing it with male and female dies for preforming. Next, the preformed plate 3 for the fin is pressed by a male die 4 and a female die 5, both for finishing press works, thereby, a porjected portion 3a1 is extended by a pressure and angles of bended portions 3a4 are enlarged in proportion to the extended length while the same portion 3a4 are pushed toward a necked portion 4C of the male die 4, thus, the jointing portion 3a having the constricted portion 3a4" is formed. A heat conducting tube 6 is press-jointed within the jointing portion 3a by separate type female press-die 7 and male press-die 8. Consequently, the constricted portions 3a4" are tightened toward each other and the heat conducting tube 6 and the plate 3 for the fin may be jointed closely with high tightness.
