Abstract
According to the present invention, an outlet tank and an inlet tank are formed in one end side of a plurality of connecting bodies and the bent portions are formed in other end side of the connecting bodies. The plurality of the connecting bodies is formed by a pair of pressed plates and is laminated to form a predetermined space in which the fin is installed, thus creating a laminated type heat exchanger. The bent portions are formed in a bottom end portion of the connecting body, and in the remaining bottom end portion of the surface, there is formed an extending portion which extends to a side lower than the bottom end portion of the fin. Therefore, even when the condensed water becomes a water drop between the surface of the connecting body and the surface of the fin, the drop does not stay for a long time and is efficiently drained by the extending portion downwardly.
