Abstract
A laminated type heat exchanger includes a plurality of tube elements laminated so as to form a first tank portion, a second tank portion, and a third tank portion in a laminated direction. Each tube element includes a first flange, a second flange, and a third flange for the first tank portion, the second tank portion, and the third tank portion, which are brazed with a first flange, a second flange, and a third flange of an adjacent tube element, respectively. The first flange is folded inside the first tank portion, the second flange is folded outside the second tank portion, and the third flange is folded outside the third tank portion. In this way, it is possible to reduce the flow resistance of the refrigerant flowing in the tank portions.
