Abstract

PURPOSE: To reduce the whole size, to lower the price, and to increase heat exchanging efficiency, of a heat exchanger, by increasing coefficient of utilization of fins so as to reach its maximum.
CONSTITUTION: The fin 11a is provided, protruding at a predetermined pitch, to the external surface of a heat transferring tube 3a positioned on the stage of utmost upstream, in the relationship that it does not protrude to the side of downstream far from a heat transferring tube 3a, determined by the flowing direction of a primary fluid 1, among the heat transferring tubes 3 arranged on the straight lines 2a, 2b,.... in parallel with the primary fluid 1. On the other hand, fins of which width in the direction that crosses at right angles with the flowing direction is wider than the width in the flowing direction of the primary fluid 1, for example, ovally annular fins 11b, are provided protrudingly to the external sufaces of heat transferring tubes 3b, positioned on the other stages at a predetermined pitch.
