Abstract
A louvered, corrugated cooling fin (42) has its louvers (48) bent out of the fin walls (44) in a novel configuration. Rather than being bent out of the fin wall (44) about central, lengthwise axes that are square to the fin wall (44), the louvers (48) are bent out, at shallow angles, about axes that run corner to corner of the louver, axes which are not square to the fin wall (44). As a consequence, rather than moving on lengthwise half of the louver (48) to each side of the fin wall (44), one diagonal half of the louver (44) is moved to each side of the fin wall (44). Another consequence is that diagonally opposed corners of the louvers (48) are shifted out of constricted areas (C) between the fin wall (44), and into less constricted areas (O), allowing greater louver length, greater effective louver opening depth (D'), and better overall air flow.
