PURPOSE: To provide a heat transfer section which can maintain an interval to other heat transfer section while suppressing its abnormal deformation by disposing a predetermined rugged shape together with a rugged shape pattern formed in a heat transfer surface and which can surely heat exchange and to provide a method for forming the heat transfer section for forming the section. CONSTITUTION: The heat transfer section comprises a heat transfer surface 110 formed by press molding one set or a plurality of sets each having a central pattern 111 in which a plurality of recesses or protrusions are arranged, a pair of heat exchanging rugged patterns 112 arranged symmetrically at both sides of the pattern 111 and a boundary pattern 113 in which a plurality of recesses or protrusions are arranged. Thus, when the plurality of the sets are superposed reversely at top and bottom and front and rear on other heat transfer section 100 so as to be combined as a heat exchanger, the pattern 111 and the pattern 113 of the superposed heat transfer sections 100 are brought into contact with each other at their protrusions to maintain a gap between the heat transfer surfaces 110, to make heat exchanging characteristics uniform and to surely maintain a strength of the overall heat exchanger. |
