Abstract

See full text

In a heat exchanger in which a number of V-shaped convex portions are arranged in parallel at a surface of a fin, one of a pair of inclined convex portions forming a V-shape is arranged to be inclined to a plus side by an angle a relative to a circulation direction of a gas at a first plane of a fin, the other is arranged to be inclined to a minus side by an angle b, and both of them are arranged by asymmetric angles in a left and right direction, and at a second plane opposed to the first plane, the angles which are asymmetric in the left and right direction are made to be reverse to those of the first plane relative to the circulation direction of the gas.
