ABSTRACT:
A heat extraction system is provided for a laptop computer that comprises a system unit that includes a set of heat sources and a video display unit that is movably attached to the system unit. The laptop computer has air inlets and air outlets that allow air to flow into the system unit, over the heat sources forming heated air, and exhaust the heated air. The laptop computer has a set of tubes, which have an inlet and an outlet, located behind a video display in the video display unit and an air connection from the air outlets to each inlet in the tubes. The set of tubes are formed such that heated air passing through a constriction in the set of tubes changes in velocity and pressure in order to satisfy the conservation of flow rate. Thus, heat produced by the heat sources is extracted from the laptop computer.
