頂部が当接して接合されるように配列されて構成
したことを特徴とする積層型熱交換器。 Tube elements and fins are alternately stacked, and the tube element has a tank-forming recess and a passage-forming recess that follows the tank-forming recess, and a large number of protrusions in the passage-forming recess are connected to the other passage. Two molded plates arranged so as to come into contact with the protrusions of the forming recesses are joined so that the tank forming recesses and the passage forming recesses face each other, and the tank is removed from the tank forming recesses of each other. In a stacked heat exchanger in which heat medium passages are formed from mutual passage-forming recesses, the abutting protrusions in the passage-forming recesses of the molded plates are alternately formed into cylindrical shapes of large and small diameters. and when forming the tube element, the large-diameter cylindrical protrusion and the small-diameter cylindrical protrusion are arranged so that their tops abut and are joined. Heat exchanger.
