Claims

[Claims for Utility Model Registration] A large number of tube elements 4 and fins 5 through which a heat medium flows in a U-shape are alternately stacked to constitute an air ventilation section 2 in which heat is exchanged by the heat medium, and In a stacked heat exchanger in which a tank element 3a constituting an adapter 3 for introducing the heat medium into each tube element 4 is joined to the tube element 4, the tank element 3a has an inlet portion at the center of its end. 9 has an outlet section 10 adjacent to the inlet section 9.
are opened respectively, and the entrance part 9
A first passage 11a through which the heat medium flows in an L-shape, and a second passage through which the heat medium that has made a U-turn inside the tube element 4 from the other end of the first passage 11a flows parallel to the first passage 11a. a second passage 11b, and a third passage 11 through which the heat medium that has made a U-turn inside the tube element 4 flows toward the outlet portion 10 from the other end of the second passage 11b.
c is formed, so that the heat medium flowing from the side surface of the heat exchanger in a direction substantially perpendicular to the air flow direction passes through the inside of the heat exchanger twice along the air flow direction. 1. A laminated heat exchanger characterized in that the air is turned and flows out from a side surface of the heat exchanger in a direction substantially perpendicular to the flow direction of the air.
