Abstract

A heat exchanger of a brazed-plate-fine type and a counter-flow type consists of a plurality of tube elements which define first-fluid flowing spaces while inner fins are disposed in the spaces, respectively. The tube elements are alternately laminated with a plurality of outer fins, and the laminated elements and fins are surrounded by a housing for constituting a second-fluid flowing space. A first-fluid inlet port and a first-fluid outlet ports are formed so as to outwardly project from a lateral side of the outer fin. The housing is formed to have curved portions conforming with projecting outer peripheries of the inlet and outlet ports. Accordingly, the heat transmission efficiency of the heat exchanger is improved.
