Long fin omni-directional heat sink

摘要

A heat sink adapted to dissipate heat from an electronic component wherein a plurality of heat dissipating perforated fins project generally outwardly from a planar base and are spaced apart by channels therebetween. The height of the perforated fins to the width of the channels is at least about 8 to 1. The perforations through the fins are such that the flow of cooling fluid through the fins generally emulates the flow through a comparable pin grid array heat sink. The fin structure is such that the fin is structurally supported against deformation, particularly during cross-cutting operations.
