Abstract:
1. A cooling system for an electronic device, the cooling system comprising: a cooling fluid flow path through which a cooling fluid flows; a variable orifice in the cooling fluid flow path and comprising an adjustable diaphragm shutter comprising overlapping blades that form an opening through which the cooling fluid flows, wherein upon manipulation of the adjustable diaphragm shutter, a diameter of the opening is adjusted to control the flow of the cooling fluid; the cooling fluid flow path comprising a pipe attached to the variable orifice and through which the cooling fluid flows to the variable orifice; a pump to force the cooling fluid through the pipe and variable orifice; and a heat exchanger that passes heat from a cooling air to the cooling fluid, wherein the pump forces the cooling fluid via the cooling fluid flow path through the heat exchanger, and wherein a fan transfers the cooling air via a cooling air flow path through the heat exchanger to across heat generating components of the electronic device.
