ABSTRACT:
Louver segments of a heat transfer fin each have a longitudinal central portion disposed at the center of the louver segment in a direction crossing the flow of a fluid and longitudinal end portions each disposed on either side of the longitudinal central portion and sectioned into parts. Each louver segment has a configuration such that an area of the longitudinal central portion projected in the direction of the flow of the fluid is larger than an area of each of the longitudinal end portions projected in the direction of the flow of the fluid, with respect to the same width of the passage of the fluid.
