Abstract
A high performance louvered fin for a heat exchanger includes a base wall extending longitudinally to form a strip having a longitudinal axis. The high performance louvered fin includes a plurality of entrance louvers in the base wall extending outwardly at a predetermined angle in a first direction from the base wall. The high performance louvered fin also includes a plurality of exit louvers in the base wall extending outwardly at a predetermined angle in a second direction from the base wall reversed from the first direction. The entrance louvers and the exit louvers extend in a direction parallel to the longitudinal axis and are spaced laterally. The high performance louvered fin further includes a turnaround rib in the base wall extending laterally and generally perpendicular to the longitudinal axis between the entrance louvers and the exit louvers.
