<p><P>PROBLEM TO BE SOLVED: To provide a method of manufacturing a heat transfer plate, the method for manufacturing the heat transfer plate which is formed by friction stirring and has high flatness. <P>SOLUTION: The manufacturing method comprises: a pipe for heating medium inserting step of inserting a pipe 20 for heating medium, in a recessed groove formed on the bottom face of a lid groove to be opened on the front surface Za side of a base member 2; and a lid groove closing step of inserting a lid plate 10 on the lid groove; a joining step of performing friction stirring by relatively moving a rotary tool for joining along the butted parts between the side walls of the lid grooves and the side surfaces of the lid plates 10; and a correction step of correcting a warp formed in the joining step and projected to the rear surface Zb side of the base member 2, by actuating bending moment to generate tensile stress to the front surface Za side of the base member 2. <P>COPYRIGHT: (C)2010,JPO&INPIT</p> |
