ABSTRACT:
A laminated heat exchanger in which tube elements and end plates can be bonded without forming gaps is provided while an end structure provides a sufficient flow passage area through the tube elements at the ends. An outside formed plate forming a tube element at one end of a laminated heat exchanger is formed flat and an end plate is bonded to the flat formed plate. The formed plate is provided with indentations and projections corresponding to those in the flat formed plate to which it is bonded face-to-face, and portions where the flat formed plate comes into contact with the end plate are formed flat or planar. The bonding margins of the end plate where it contacts the flat formed plate are formed so as to avoid areas which include indentations and projections in the flat formed plate. The end plate is formed so as to cover the entire surface of the flat formed plate.
