<p>In the laminated heat exchanger according to the present invention, in which the heat exchanging medium flows into a specific tank portion (9a,9b) via a communicating passage (28) that is connected to a surface that is at a right angle to the direction of the lamination, a reinforced portion (41) is formed in the tank portion that faces opposite the opening portion of the communicating passage (communicating pipe) (28) in order to minimize the likelihood of a rupture at the shoal-like bead (36c) near the communicating passage, among the shoal-like beads formed in the area where the tank portions change to the U-shaped passage portion. <IMAGE></p> |
