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.

What is claimed is: 1. A laptop computer comprising: a system unit, wherein the system unit includes a set of heat sources; a video display unit movably attached to the system unit; a set of air inlets and a set of air outlets on the system unit, wherein the set of air inlets allows air to flow into the system unit, wherein the air flows over the heat sources within the system unit to form heated air, and wherein the set of air outlets allows the heated air to flow out of the system unit; a set of tubes located behind a video display within the video display unit, wherein each tube in the set of tubes has an inlet and an outlet in the video display unit; an air connection, wherein the air connection connects the set of air outlets to each inlet in the set of tubes, wherein the set of tubes have a form such that heated air passing through a constriction in the set of tubes changes in velocity and pressure in order to satisfy conservation of flow rate, and wherein the heated air produced by the set of heat sources is extracted from the laptop computer through each outlet in the set of tubes. 2. The laptop computer of claim 1, wherein the heated air gains kinetic energy as it enters the constriction and wherein the kinetic energy is supplied by a first pressure gradient force of the heated air behind the constriction. 3. The laptop computer of claim 2, wherein the first pressure gradient reduces the pressure in the constriction in reaction to an acceleration. 4. The laptop computer of claim 3, wherein the heated air leaving the constriction is slowed by a second pressure gradient force that raises the pressure back to an ambient level. 5. The laptop computer of claim 1, wherein a number of the set of air inlets, the set of air outlets, and the set of tubes is determined based on an amount of cooling necessary to cool the system unit. 6. The laptop computer of claim 1, wherein the set of air inlets are on a front of the system unit. 7. The laptop computer of claim 1, wherein the set of air outlets are on a rear of the system unit. 8. The laptop computer of claim 1, wherein the set of tubes extend from a bottom of the video display unit to a top of the video display unit. 9. The laptop computer of claim 1, wherein the heated air connection from the set of air outlets to the set of tubes is a hinged duct. 10. The laptop computer of claim 1, wherein the heated air connection from the set of air outlets to the set of tubes is an expandable/collapsible tube. 11. A laptop computer comprising: a system unit, wherein the system unit includes a set of heat sources; a video display unit movably attached to the system unit; a set of air inlets and a set of air outlets on the system unit, wherein the set of air inlets allows air to flow into the system unit, wherein the air flows over the heat sources within the system unit to form heated air, and wherein the set of air outlets allows the heated air to flow out of the system unit; a set of fans, wherein the set of fans draw air from the set of air inlets and exhaust the heated air through the set of air outlets; a set of tubes located behind a video display within the video display unit, wherein each tube in the set of tubes has an inlet and an outlet in the video display unit; an air connection, wherein the air connection connects the set of air outlets to each inlet in the set of tubes, wherein the set of tubes have a form such that heated air passing through a constriction in the set of tubes changes in velocity and pressure in order to satisfy conservation of flow rate, and wherein the heated air produced by the set of heat sources is extracted from the laptop computer through each outlet in the set of tubes. 12. The laptop computer of claim 11, wherein the heated air gains kinetic energy as it enters the constriction and wherein the kinetic energy is supplied by a first pressure gradient force of the heated air behind the constriction. 13. The laptop computer of claim 12, wherein the first pressure gradient reduces the pressure in the constriction in reaction to an acceleration. 14. The laptop computer of claim 13, wherein the heated air leaving the constriction is slowed by a second pressure gradient force that raises the pressure back to an ambient level. 15. The laptop computer of claim 11, wherein a number of the set of air inlets, the set of air outlets, and the set of tubes is determined based on an amount of cooling necessary to cool the system unit. 16. The laptop computer of claim 11, wherein the set of air inlets are on a front of the system unit. 17. The laptop computer of claim 11, wherein the set of air outlets are on a rear of the system unit. 18. The laptop computer of claim 11, wherein the set of tubes extend from a bottom of the video display unit to a top of the video display unit. 19.
