Abstract:
A heat exchanger (100) comprises a plurality of tubes (10) that are formed into flat shapes having a pair of opposite faces (11, 12) facing each other and that are disposed in layers with spaces therebetween, and channels (40) that are formed inside the tubes (10) and in which a fluid to perform heat exchange with the exterior of the tube (10) flows. A plurality of projections (15 or 16) are formed on at least one of the pair of opposite faces (11, 12) so as to project into the channel (40) along the direction that the fluid flows. The plurality of projections (for example, 15) have ends (15a) formed on both sides of the tube (10) in the width direction that are connected to approximately V-shaped vertices (15b) on the projections (15) wherein a portion of the projection (15) is formed into an approximate V-shape at a prescribed angle θ to the direction of flow of the fluid. The vertex (15b) is arranged in the same direction of the vertex (15b) of the adjacent projection (15).
