Abstract
Hand held equipment has a body and a heat sink. The body defines an outer surface and a heat source therewithin. The heat sink forms a portion of the outer surface and is positioned in close proximity to the heat source so as to conduct heat therefrom. The heat sink has a base, a plurality of fins and a coating having low thermal conductivity (which may be a ceramic coating). The base has a lower and an upper surface. The lower surface is in close proximity to the heat source. The plurality of fins has a proximal end meeting the upper surface of the base, and a distal end extending away from the base. Each of the plurality of fins define a cross-sectional area and terminate at an outward surface. The coating extends over at least a portion of the outward surface of the plurality of fins. A heat sink is likewise disclosed.
