<P>PROBLEM TO BE SOLVED: To provide a heat transfer plate for a plate type heat exchanger, with improved handleability in assembling or decomposition. <P>SOLUTION: The heat transfer plate for a plate type heat exchanger includes: a plurality of linear recesses and protrusions which are formed by press molding on both surfaces of a substantially rectangular metal plate to be inclined with respect to a virtual line extending in a width direction orthogonal to a longitudinal direction; and an annular gasket groove where a gasket is arranged to form a flow path in an area including the linear recesses and protrusions. The gasket groove includes a pair of straight parts along both edges of the metal plate in the width direction orthogonal to the longitudinal direction. The linear recesses and protrusions within a predetermined range along each straight part inside in the width-direction are inclined opposite to those in the symmetrical positions inside in the width-direction based on the boundary of the predetermined range inside in the width-direction. <P>COPYRIGHT: (C)2012,JPO&INPIT |
