Abstract:
An air duct capable of using a first air flow, the first air flow having a first velocity for cooling at least one component capable of producing a quantity of heat, said air duct comprising:an intake manifold having a first volume comprising a first area and a first length, said first air flow operatively engaged to said intake manifold, a restriction chamber having an opening and a second volume comprising a second area and a second length, said second area of said restriction chamber smaller than said first 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 larger 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 by combining said first air flow and said second air flow, and an exhaust manifold, said exhaust manifold having an exhaust opening and a third volume, said third volume having a third area and a third length, said third area of said exhaust manifold larger than said second area of said restriction chamber, said third area coupled to said second area allowing said third air flow to expand and have a third velocity, said third air flow exits said exhaust manifold through said exhaust opening; and wherein said first air flow mixes with said second air flow such that said second air flow does not pass over said at least one component.
