An active heat sink structure includes at least one heat sink. Each heat sink includes a heat sink base having a top surface with a top surface periphery, a top surface center at a central portion of the top surface, and an oppositely disposed bottom surface. The top surface is preferably flat. The heat sink may be described in relation to a first reference line lying in the top surface and a second reference line lying in the top surface and perpendicular to the first reference line. Where there is more than one heat sink, the heat sinks lie adjacent to each other along the first reference line. A plurality of air flow paths are defined on the top surface of the heat sink base, preferably by fins extending perpendicular to the top surface. Substantially all of the air flow paths direct a flow of air from the top surface center toward the top surface periphery and substantially parallel to the second reference line. An air-flow source such as a fan directs air into the plurality of air flow paths from a location at about the top surface center. |
