Claims

[Scope of utility model registration request]

In a heat exchanger in which a first heat exchange medium flows through the outer surface of the tube and a second heat exchange medium flows through the inner surface of the tube, only one cylindrical portion 1 having a tapered peripheral surface and an oblong plane is provided. The fin element 2 is formed by deep drawing in the center of a substantially rectangular metal plate piece, and the long axis of the oval shape is positioned substantially on a diagonal line of the metal plate, and the cylindrical portion 1 is formed by deep drawing. A large number of the fin elements 2 are fitted into each other.
are laminated, and the fitting portions are liquid-tightly brazed and fixed to each other to form a finned tube 3, and each of the plurality of finned tubes 3 has its long axis aligned with the flow of the first heat exchange medium. 4, and are shifted in the front and back direction of the flow 4, and the tubes 3 are arranged at intervals narrower than the width b of the metal plate in the direction perpendicular to the flow 4. A heat exchanger characterized by the following:
