Abstract
Described herein is a heat exchanger comprising a plurality of plate fins. At least one plate fin comprises a plurality of holes arranged in one or more rows, and a contoured region formed adjacent to one of the plurality of holes and having a sinusoidal corrugation. The contoured region comprises a plurality of elongate adjustable lance elements, wherein the sinusoidal corrugation in each of the rows comprises three half-waves of a first wave size in the middle portion of the corresponding row, and two half-waves of a second wave size on lateral ends of the corresponding row, wherein the second wave size is smaller than the first wave size.
