HEATSINK STRUCTURE

摘要

An heat sink (10) is disclosed in which a plurality of heat conducting fins (20) extends from a base of heat conductive material. The top surface (14) 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 (18) 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.
