Abstract
A cooling system has a heat sink having a plurality of fins. A fan is positioned near the heat sink to blow air between the fins. A flow converging device is positioned between the fins and the fan, to cause air from the fan to converge on a predetermined region of the heat sink. The flow converging device may be, for example, a plurality of wedges or a body having a frustum shaped opening through the body.
Claims17
A cooling system, comprising:
- a heat sink having a plurality of fins;
- a fan positioned near the heat sink to blow air between the fins;
- and
- a flow converging device from the group consisting of a plurality of wedges and a body having a frustum shaped opening therethrough, the flow converging device positioned between the fins and the fan, to cause air from the fan to converge on a predetermined region of the heat sink.

A cooling system, comprising:
- a heat sink having a plurality of fins;
- a fan positioned near the heat sink to blow air between the fins;
- and
- flow converging means positioned between the fins and the fan, to cause air from the fan to converge on a predetermined region of the heat sink.
1 more element
A method for cooling a device, comprising the steps of:
- (a) generating an air flow having an outer region with a first flow velocity and an inner region with a second flow velocity less than the first flow velocity;
- (b) directing the air flow through a converging device, so the air flow from the outer region is converged into the inner region;
- and
- (c) directing the converged air flow between a plurality of fins on a predetermined region of a heat sink.
