Abstract
In a laminated heat exchanger in which a heat exchanging medium flows into a specific tank portion via a communicating passage that is connected to a surface that is at a right angle to the direction of the lamination, a reinforced portion is formed in the tank portion that faces opposite the opening portion of communicating passage (communicating pipe). The reinforced portion minimizes the likelihood of a rupture at the shoal-like bead near the communicating passage, which is provided among shoal-like beads formed in an area where the tank portions change to a U-shaped passage portion.
