Abstract
In this heat exchanger, an improvement comprises the following. The fin plates each have louvered portions interposing the aligned openings in the fin plates. The louvered portions in each fin plate define a nominal plane and include a plurality of louvers and a base. The base has base portions including rise portions and flank portions, three each. The rise portions and flank portions alternate with each other in a transverse direction across the width of the fin plate. The rise portions and flank portions form three peaks, which are a central peak and two outer peaks. The peaks are raised in a first direction perpendicular to the nominal plane. The rise portions and flank portions further form two valleys in the opposite, second direction perpendicular to the nominal plane. The valleys are spaced from each other and are each between the central peak and an outer peak. The rise portions are substantially parallel to each other and intersect the nominal plane at a first acute angle. The flank portions are substantially parallel to each other and intersect the nominal plane at a second acute angle substantially equal in degree and opposite in direction to the first acute angle.
