Abstract:
A heat sink for cooling an electronic component of a computer, comprising:a substanlially horizontal thermally conductive plate having a lower surface positionable on the electronic component so that heat is transferred from the electronic component to the plate; and a thermally conductive wall structure which defines a surrounding enclosure when viewed from above, and extends substantial vertically from a lower end to an upper end thereof, a periphery of the lower end being secured to the plate so that the heat can conduct from the plate through a lower portion of the wall structure to successive upper portions of the wall structure, a plurality of openings being defined at different elevations by the wall structure below respective ones of the upper portion through which air can enter at different elevations into the enclosure, flow upwardly over an inner surface of the wall structure next to the respective upper portions so that the heat is convected thereto, and exit through the upper end out of the enclosure.
