Claims

[Claims for Utility Model Registration] 1. Tube elements and fins are alternately laminated, and the tube element is composed of two molded plates in which a tank-forming recess and a passage-forming recess continuing from the tank-forming recess are formed. A stacked heat exchanger in which the tank-forming recess and the passage-forming recess are joined so that they face each other, and a tank is formed from each tank-forming recess, and a heat exchange medium passage is formed from each other's passage-forming recess. A plurality of protrusions projecting toward the other molding plate are formed in the passage-forming recess of the molding plate, and the protrusions are cylindrical and have a flat top,
A laminated heat exchanger characterized in that the top of one molded plate and the top of the other molded plate are joined to each other and arranged in a staggered manner. 2. The laminated layer according to claim 1 of the utility model registration, characterized in that the passage forming recess of the molded plate has an area ratio of approximately 20 to 10 to 80 to 90 of the protrusion and the remaining portion other than the protrusion. type heat exchanger.
