Abstract:
1. A cooling system for a computer comprising: a heat spreader that is in thermal contact with a heat generating component in the computer; a frame casting of the computer; a heat pipe to passively dissipate heat generated from the heat generating component in the computer to the frame casting, the heat pipe including, a radial fan to cool each of the heat pipe, the frame casting and the heat spreader by exhausting air from the computer through a vent in the frame casting, wherein the second portion of the heat pipe is disposed over the vent such that the air exhausted through the vent by the radial fan actively cools both the second portion of the heat pipe and the frame casting, and wherein a top surface of the heat spreader includes a plurality of channels pointing to a center of the radial fan to reduce resistance of air flow in the computer to the radial fan.
