Abstract:
A heat sink for electrical or electronic components comprising:a heat spreader plate having a first surface and a second surface in which said first surface includes a recessed area having a volumetric space suitable for connecting and recessing a computer chip and in which said second surface includes a flat area; at least three heat conducting fins having equal heights and lengths corresponding to the radial lengths necessary to span the distance from the center of said spreader plate to the edge of said flat area and positioned adjacent to one another in a substantially radial configuration that are connected substantially perpendicular to said flat area of said second surface of said heat spreader plate; and an array of heat conducting reticulated foam blocks having heights about equal to said fins that are positioned in-between at least two adjacent radial fins wherein said foam blocks between said at least two adjacent radial fins are spaced one from another in a like radial direction such that each two adjacent ones of said foam blocks define a gap therebetween.
