Abstract
A fin for use on a heat exchanger and a method for making the same. The fin is made by stamping individual columns of openings in the fin such that adjacent columns are equally spaced apart. The outermost column of openings is spaced from a side edge of the fin a distance that is about one-half of the distance between adjacent columns of openings. The uniform spacing allows for the construction of a fin requiring any number of columns of openings to correspond to the tube portion that is used to form the heat exchanger. This spacing provides for an efficient and compact design of the tube portion and of the heat exchanger formed with the tube portion and the fins.
