Abstract

A cooling system has a heat sink having a plurality of fins. A fan is positioned near the heat sink to blow air between the fins. A flow converging device is positioned between the fins and the fan, to cause air from the fan to converge on a predetermined region of the heat sink. The flow converging device may be, for example, a plurality of wedges or a body having a frustum shaped opening through the body.
