NON-UNIFORM HEIGHT AND DENSITY FIN DESIGN FOR HEAT SINK

摘要

A heat sink includes a heat sink plate and a heat generating electrical component mounted to a first side of the heat sink plate. Fins are connected and oriented perpendicular to a second side of the heat sink plate. The fins include a maximum height fin positioned proximate to the electrical component, and a minimum height fin spatially separated from the maximum height fin and the electrical component. A first group of fins is positioned between the maximum and minimum height fins. Each fin of the first group progressively decreases in height from a height of the maximum height fin to a height of the minimum height fin. A first spacing between the maximum height fin and a proximate one of the fins of the first group is less than a second spacing between any two consecutive ones of the first group of fins.
