Heat is removed from a docked portable computer. Due to the heat removal, the portable computer can operate at full design voltage and frequency while docked, and thereby provide maximum performance, without sacrificing performance in order to generate less heat. A docking station provides a thermal docking connection. The thermal docking connection is implemented using a first set of fins of the portable computer that is mated to a second set of fins in the docking station. The second set of fins in the docking station is then, via use of heat conductive materials, exposed to forced airflow from a fan within the docking station. Other embodiments of heat-removal methods, such as larger surface areas, peltia devices, water cooling, and others, can be used to pull additional heat from the docked portable computer. Thus, the docking station acts as an "air-conditioner" for the portable computer, and allows the portable computer to operate at higher frequencies.

Claims

1. A system, comprising:

a portable device that generates heat during operation;
a docking station having a connection to accommodate the portable device, the connection being coupleable to the portable device to receive the heat generated by the portable device during operation of the portable device while in the docking station; and
a heat transport mechanism included with the docking station to substantially remove the heat received by the connection.

2. The system of claim 1 wherein the portable device comprises a hand-held computer.

3. The system of claim 1 wherein the heat transport mechanism comprises a fan to generate an airflow that flows over the connection to remove the heat therefrom.

4. The system of claim 1 wherein the heat transport mechanism includes a liquid coolant to remove the heat from the connection.

5. The system of claim 1 wherein the portable device includes a first set of fins to dissipate the heat generated by the portable device, and wherein the connection of the docking station includes a second set of fins having:

a first side of fins coupled to substantially mate with the first set of fins of the portable device to receive the heat dissipated by the first set of fins; and
a second side of fins, positioned opposite to the first side of fins, to allow removal of the heat received by the first side of fins by the heat transport mechanism.

6. The system of claim 5 wherein the second set of fins comprises a male-to-male arrangement, and wherein the first set of fins of the portable device comprises a female arrangement.

7. The system of claim 5 wherein the fins of either the first set of fins or the second set of fins comprises at least one of a rectangular shape, triangular shape, spherical shape, and arcuate shape.

8. The system of claim 5 wherein the first set of fins is located at a rear area of an underside surface of the portable device.

9. The system of claim 5 wherein the fins of either the first set of fins or the second set of fins comprises at least one of a magnesium alloy and copper.

10. The system of claim 1 wherein the connection of the docking station includes a peltia device to receive the heat generated by the portable device.

11. The system of claim 10 wherein the docking station further comprises:

a heat conductive material, positioned over a first region of the peltia device and comprising part of the connection, to mate with the portable device to receive the heat generated therefrom; and
a source, coupled to the first region of the peltia device and to a second region of the peltia device, to activate the peltia device in a manner that the first region becomes cooler relative to the second region to draw the heat from the portable device through the heat conductive material, wherein the drawn heat is transferred from the first region to the second region, and wherein the heat transport mechanism is coupled to remove the transferred heat from the second region.

12. The system of claim 1 wherein an underside surface of the portable device is thermally coupled to its internal components that generate the heat, the underside surface being coupleable to the connection of the docking station to allow dissipation of the heat from the underside surface.

13. The system of claim 1 wherein the portable device includes a set of fins to dissipate the heat generated by the portable device.

14. The system of claim 1 wherein the portable device comprises at least one of a wireless communication device, display device, monitor, audiovideo equipment, and consumer electronic device.

15. An apparatus, comprising:

a docking station to receive a portable computer that generates heat while the portable computer is in operation, the docking station including:
a thermal docking connection that can be mated with the portable computer while the portable computer is in the docking station, the thermal docking connection being mated to the portable computer in a manner that draws the heat, generated by the portable computer, from the portable computer; and
a heat removal element to substantially remove the heat drawn from the portable computer.

16. The apparatus of claim 15 wherein the heat removal element comprises a fan that generates an airflow that can carry the heat away from the thermal docking connection.

17. The apparatus of claim 15 wherein the portable computer includes a plurality of fins, and wherein the connection of the thermal docking station includes another plurality of fins that substantially mate with the fins of the portable computer to transfer the heat from the fins of the portable computer, the heat removal element being positioned in a manner that substantially removes the transferred heat from the fins of the connection.

18. The apparatus of claim 15 wherein the connection comprises a peltia device to cool the portable computer.

19. The apparatus of claim 15 wherein the thermal docking connection comprises a heat transfer material positioned between the portable computer and the docking station.

20. The apparatus of claim 19 wherein the heat transfer material comprises air, and wherein the heat removal element comprises a fan to fan that air.

21. A method, comprising:

docking a portable device to a docking station;
operating the portable device while docked in the docking station; and
using the docking station to remove heat generated by the portable device while operating in the docking station.

22. The method of claim 21 wherein using the docking station to remove the heat includes fanning the portable device from the docking station.

23. The method of claim 21 wherein using the docking station to remove the heat includes:

substantially mating fins of the docking station with fins of the portable computer to transfer the generated heat to the fins of the docking station; and
removing the transferred heat from the fins of the docking station.

24. The method of claim 21 wherein using the docking station to remove the heat includes using a peltia device in the docking station to cool the portable computer.

25. The method of claim 19, further comprising raising an operating frequency of the device while docked in the docking station to a level above an operating frequency while in hand-held operation.
