An electronic device has at least one component that is capable of generating a quantity of heat. The electronic device further has an air-moving device and an air duct. The air moving device is capable of creating a flow of air that removes a portion of the quantity of heat. The flow of air enters the air duct. The air duct has a restriction chamber that includes a venturi vent in which the flow of air into the duct and through the restriction chamber creates a new flow of air into the venturi vent. The new flow of air into the venturi vent does not pass over the at least one component in the electronic device.

What is claimed is: 1. An air duct capable of using a first air flow, the first air flow having a first velocity for cooling at least one component, said air duct comprising: an intake manifold having a first cross-sectional area, said first air flow operatively engaged to said intake manifold, a restriction chamber having an opening and a second cross-sectional area, said second cross-sectional area of said restriction chamber less than said first cross-sectional area of said intake manifold, wherein said restriction chamber is coupled to said intake manifold to receive said first air flow, said first air flow having a second velocity in said restriction chamber, said second velocity more than said first velocity, said first air flow flowing across said opening thereby creating a second air flow into said opening from external to said restriction chamber thereby forming a third air flow, and an exhaust manifold, said exhaust manifold having an exhaust opening and a third cross-sectional area, said third cross-sectional area coupled to said second cross-sectional area wherein said third air flow exits said exhaust manifold through said exhaust opening; and wherein said second air flow does not pass over said at least one component. 2. The air duct of claim 1 wherein said opening in said restriction chamber is flared. 3. A processor module comprising the air duct of claim 1. 4. An electronic device comprising the air duct of claim 1. 5. An air duct for receiving a flow of air over at least one component, comprising, a restriction chamber, said restriction chamber having a first end and a second end, and said restriction chamber having at least one venturi vent, an intake manifold, said intake manifold capable of being operatively engaged to the flow of air and further operatively engaged to said first end of said restriction chamber, and an exhaust manifold coupled to said second end of said restriction chamber; wherein said at least one venturi vent creates a vacuum air flow, and wherein said vacuum air flow does not pass over said at least one component. 6. A processor module comprising the air duct of claim 5. 7. An electronic device comprising the air duct of claim 5. 8. A cooling apparatus for an electronic device having a first component creating a first heated air mass and a second component creating a second heated air mass, said apparatus comprising: means for mixing a first air flow and a portion of said first heated air mass thereby creating a mixed air flow means for restricting said mixed air flow by channeling said mixed air flow through a restriction chamber thereby increasing the velocity of the mixed air flow; means for creating a first vacuum pressure having a second air flow in a first opening in said restriction chamber; and means for mixing said mixed air flow and said second air flow thereby creating a combined air flow. 9. The apparatus of claim 8, further comprising: means for exhausting said combined air flow outside of said electronic device. 10. The apparatus of claim 8, further comprising means for mixing said second air flow and a portion of said second heated air mass. 11. The apparatus of claim 8, further comprising: means for mixing said second air flow and a quantity of air external to said electronic device. 12. The apparatus of claim 8, further comprising: means for coupling thermally said at least one component to said restriction chamber using a heat pipe. 13. The apparatus of claim 8, further comprising: means for mixing said first air flow and a portion of said second heated air mass; and means for mixing said second air flow and a quantity of air external to said electronic device. 14. The apparatus of claim 8, further comprising: means for creating a second vacuum pressure having a third air flow in a second opening in said restriction chamber thereby creating a second venturi vent; means for mixing said first air flow and a portion of said first heated air mass; means for mixing said second air flow and a portion of said second heated air mass; and means for mixing said third air flow and a quantity of air external to said electronic device. 15. The apparatus of claim 8, further comprising: means for sensing temperature within said electronic device; and means for releasing said first air flow from a compressed gas container in response to said sensing of temperature. 16. The apparatus of claim 15, further comprising: means for mixing said first air flow and a portion of said first heated air mass; and means for mixing said second air flow and a portion of said second heated air mass. 17. The apparatus of claim 15, further comprising: means for mixing said first air flow and a portion of said second heated air mass; and means for mixing said second air flow and said first heated air mass. 18. The apparatus of claim 8, further comprising: means for restricting said first heated air mass to an enclosure container containing said at least one component; means for coupling said first heated air mass in said enclosure to said venturi vent; means for mixing said first air flow and a portion of said second heated air mass; and means for mixing said second air flow and a portion of said first heated air mass. 19. The apparatus of claim 8, further comprising: means for coupling a third heated air mass from a second cavity on said electronic device to said first venturi vent. 20. The apparatus of claim 8, further comprising: means for coupling a quantity of air external to said electronic device to said first venturi vent using an air duct; means for coupling said first heated air mass to said air duct; and means for mixing said first heated air mass to said quantity of air external to said electronic device to form said second air flow. 21. An electronic device, comprising: an air moving device adapted to create a first air flow; and a cooling apparatus, including, a restriction chamber having a venturi vent, the chamber adapted to restrict said first air flow by channeling said first air flow thereby increasing the velocity of said first air flow over the venturi vent, the venturi vent adapted to create a vacuum pressure having a second air flow in a first opening in said restriction chamber, the chamber further adapted to mix said first air flow and said second air flow thereby creating a combined air flow; and an exhaust manifold adapted to exhaust said combined air flow. 22.
