Abstract
A heat extraction and cooling system which can be attached to the central processing unit (CPU) of a computer for exchanging heat through an enclosure which houses a ducted fan. The apparatus includes a dual section rotary blade system that is driving by a conventional direct current motor. The apparatus also includes a heat conducting base that is placed in thermal engagement with the CPU. Attached to the base is a uniquely configured heat dissipating member which includes a plurality of upstanding heat dispensing fins, a generally conically shaped shroud and is provided with a plurality of apertures for drawing the flow of cooling air through the shroud and past the fins of the heat dissipating member. The dual section rotary blade system pulls air inwardly through the apertured shroud, past the heat dissipating fins and into the hub portion of the rotary blade system. The heat air is then forced into the interior of the uniquely configured, hollow blades which are attached to the hub portion. Each of the blades is provided with a leading edge portion and trailing edge portion having a plurality of small apertures formed therein. As the blades rotate, a negative pressure is formed proximate the trailing edge of each blade and the heated gases are expelled through the small apertures. This provides a jet thrust action to the rotating assembly and causes the heated gases expelled from the hollow blades to expand rapidly thereby producing an additional cooling effect.
