ABSTRACT:
An improved heat sink is disclosed in which a plurality of heat conducting fins extends form a base of heat conductive material. The top surface of the base is peaked to reduce the dead space that would otherwise occur during vertical impingement air flow. In the preferred embodiment, the top surface is pyramidal in shape with the peak at the center. In other embodiments, the top surface can be convex or concave and have the peak located off center. Also, webs of material can be left at the bottom of the cooling fins to provide channels for improved air flow.
