Abstract
A heat exchanger including a plurality of parallel fins, and at least one tube passing through the parallel fins, wherein the tube carries a fluid that exchanges heat with air passing through the heat exchanger. The parallel fins each include a plurality of air deflecting members formed therein. Each air deflecting member is bent substantially orthogonally relative to a planar surface of each fin, and each air deflecting member is configured to direct the air passing through the heat exchanger to increase turbulence of the air, and to impinge the air against adjacent parallel fins, and to balance air flow across the heat exchanger and decrease maldistribution of the air flow through the heat exchanger.
