Abstract

A heat exchanger including plate fins stacked at respective intervals relative to one another, and heat exchanger tubes penetrating the fins in. The heat exchanger exchanges heat between first and second fluids flowing, respectively, inside and outside the heat exchanger tubes. Each of the fins includes a substantially planar main body and cut-raised portions extending from the main body and disposed at an upstream side of flow of the second fluid. Each of the cut-raised portions corresponds to a respective heat exchanger tube and includes first and second opposed side ends connected to the main body of the fin. The first side end is nearer to the corresponding heat exchanger tube than is the second side end, the first side end is longer than the second side end, and the first side end is disposed at a downstream side of the flow of the second fluid, facing the corresponding heat exchanger tube.
