Abstract:
An active heat sink structure comprising at least one heat sink, each heat sink comprising:a heat sink base having a top surface with a top surface periphery and a top surface center, the heat sink being 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, and an oppositely disposed bottom surface, wherein a thickness of the heat sink base, as measured by a distance between the top surface and the bottom surface, is greater at the top surface center than at the top surface periphery; a plurality of fins extending outwardly from the top surface of the heat sink base, the fins being oriented to direct a flow of air from the top surface center, along the top surface, toward the top surface periphery, and substantially parallel to the second reference line when the air flow reaches the top surface periphery; and an air-flow source directing air into the plurality of air flow paths from a location at about the top surface center.
