Kind Code:
A1
Abstract:
Provided is a method for manufacturing a heat transfer plate with which it is possible to prevent a shortage of metal at a joining portion. A method for manufacturing a heat transfer plate (1), wherein the method is characterized by including: a sealing-off step in which a lid plate (3) is inserted into a lid groove (13) that is open to a surface (2a) of a base material (2) and that has a recessed groove (12) formed in a bottom surface thereof; a disposition step in which a reinforcing member (4) is disposed so as to contact the surface (2a) of the base member (2) or a surface (3a) of the lid plate (3); and a friction stirring step in which a stirring pin (F2) of a rotation tool (F) is inserted from a surface (4a) side of the reinforcing member (4) while being caused to rotate, the rotation tool (F) is caused to rotate relatively along a portion (J1) where a side surface of the lid groove (13) and a side surface of the lid groove (3) abut while only the stirring pin (F2) is caused to contact the base member (2), lid plate (3), and reinforcing member (4), and and base member (2), lid plate (3), and reinforcing member (4) are joined.
