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.
Claims12
A heat exchanger for first and second fluids, comprising:
- a plurality of tube elements defining first fluid flowing spaces, respectively;
- a plurality of inner fins disposed in the first-fluid flowing spaces of said tube elements, respectively;
- a first-fluid inlet port connected to said tube elements so as to guide the first fluid into the first-fluid flowing space, said first-fluid inlet port being located so as to outwardly project from a lateral side of said inner fins;
- a first-fluid outlet port connected to said tube elements so as to discharge the first fluid from the first-fluid flowing space, said first-fluid inlet port being located to outwardly project from the lateral side of said inner fin;
- a plurality of outer fins alternately laminated with said tube elements;
- a housing surrounding said tube elements and defining a second-fluid flowing space therebetween, said housing having a second-fluid inlet port and a second-fluid outlet port, said housing being formed so as to be curved along a peripheral wall of said tube element which defines said first-fluid inlet and outlet ports.
