Patent ID: 7028753

Claim:
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.
