Abstract
A method for manufacturing a heat transfer member comprises the step of subjecting material to be worked, which is made of a metallic thin sheet, to a press forming utilizing upper and lower molds of a press-forming devices to form the material to be worked into a shape having prescribed irregularities, thereby preparing a heat transfer member for a heat exchanger. An elongated material is used as the material to be worked. A press-forming device is provided with molds each having a length shorter than the elongated material to be worked. The press forming is carried out by press-forming, while feeding the elongated material to be worked in a single feeding direction in parallel with a longitudinal direction of the elongated material to be worked, the elongated material to be worked on prescribed portions thereof, which have been previously set so as to be placed at prescribed intervals in the longitudinal direction of the elongated material to be worked, utilizing the press-forming device, thereby preparing the heat transfer member having a plurality of patterns of irregularities, which are arranged in the longitudinal direction of the elongated material to be worked.
