Abstract

The present invention provides a heat exchanger for transferring heat between a first working fluid and a second working fluid. The heat exchanger can include a corrugated fin positionable along a flow path of the first working fluid between adjacent tube walls and being operable to increase heat transfer between the first working fluid and the second working fluid. The fin can include a leg defined between adjacent folds. The heat exchanger can also include a plurality of convolutions extending inwardly from a distal end of the leg and terminating at different distances from the end.
