Heat sink and fabricating method of the same

摘要

A heat sink includes a base having a first surface thermally connected to a heat producing component and a plurality of fins supported by a second surface of the base and arranged in a predetermined direction, each fin having a plurality of through-holes. The base and the plurality of fins are integrally formed from a porous material, for example a lotus-shaped porous material. The heat sink is placed within a duct. The heat sink may have a width of about 10 mm or less.
