Abstract
A method for manufacturing a heat transfer member comprises the step of subjecting a material to be worked, which is made of a metallic thin sheet, to a press forming utilizing a press-forming device to form a heat transfer member for a heat exchanger. The heat transfer member has on at least one portion thereof a heat transfer face that has opposite surfaces, which are to be come into contact with heat exchange fluids, respectively. The press-forming device comprises a pair of main molds for forming the heat transfer face on the material, which is to be conveyed in a single feeding direction, and two pairs of first auxiliary molds, which are disposed on upstream and downstream sides of the pair of main molds in the feeding direction of the material, so as to be exchangeable. Portions of the material are subjected to the press forming utilizing at least one pair of the pair of main molds and the two pairs of first auxiliary molds to form the heat transfer member having press-formed portions in a prescribed pattern.
