Abstract

The present invention relates to a heat exchanger. According to the present invention, heat transfer pins, in which gap alignment protrusions are formed in a stepped manner with respect to a pin main body on a metal thin film, are applied so that the heat transfer pins are aligned with a constant and relatively wide gap in the length direction of a heat transfer tube so as to be conveniently fixedly installed, and so that the manufacture and assembly of the heat transfer pins are facilitated. Also, heat transfer performance can be improved by preventing water from forming in the vicinity of the heat transfer pins as happens in the related art.
