Claim Text:
1. A heat sink comprising: a lower base having an upper surface and a lower surface; an upper cover having an upper surface and a lower surface; the cover and the base being assembled so that the upper surface of the base and the lower surface of the cover are in adjacent facing relation, and the base and the cover thereby form a solid heat sink body, said upper surface of said cover receiving a heat producing device in heat conducting engagement; a canal wall defined on at least one of: the lower surface of the cover and the upper surface of the base, so that an air flow channel is defined at least partially by the canal wall when the cover and the base are in assembled relation; the air flow channel extending from a first channel opening defined on the heat sink body to a second channel opening defined on the heat sink body; a fan comprising a rotor, a plurality of fan blades secured to the rotor, and a motor connected to the rotor; and a fan brace rotationally fixing the fan within said air flow channel adjacent said first channel opening with said rotor being axially aligned with said air flow channel, said fan moving air through said channel so that air is drawn into the air flow channel from the first channel opening and is pushed out of said air flow channel through the second channel opening.
