Abstract

In one aspect, an apparatus comprises a housing, a heat-generating component, a heat spreader, and a heat-transfer pipe. The housing forms a cavity in which the heat-generating component is located. The heat spreader is operable to distribute heat over a portion of the housing. The heat-transfer pipe is pivotally coupled to the heat-generating component and the heat spreader. The heat-transfer pipe operable to transfer heat from the heat-generating component to the heat spreader. The heat-transfer pipe and the heat spreader are movable between a first configuration and a second configuration. In the first configuration, a gap separates the heat spreader and the portion of the housing based on the heat-transfer pipe being at a first orientation. In the second configuration, the heat spreader closes the gap and is thermally coupled to the portion of the housing based on the heat-transfer pipe being at a second orientation.

First claim

What is claimed is:

1. An apparatus comprising:
a housing forming a cavity;
a heat-generating component within the cavity;
a heat spreader operable to distribute heat over a portion of the housing; and
a heat-transfer pipe pivotally coupled to the heat-generating component and the heat spreader, the heat-transfer pipe operable to transfer heat from the heat-generating component to the heat spreader, wherein the heat-transfer pipe and the heat spreader are movable between a first configuration and a second configuration, wherein:
in the first configuration, a gap separates the heat spreader and the portion of the housing based on the heat-transfer pipe being at a first orientation, and
in the second configuration, the heat spreader closes the gap and is thermally coupled to the portion of the housing based on the heat-transfer pipe being at a second orientation.

2. The apparatus of claim 1 , wherein the heat-transfer pipe comprises at least
one bend forming continuous, noncollinear portions of the heat-transfer pipe.

3. The apparatus of claim 1 , wherein the heat-transfer pipe is a first heat-transfer pipe and the heat spreader is a first heat spreader, and further comprising:
a second heat-transfer pipe and a second heat spreader, wherein the second heat-transfer pipe is pivotally coupled to the heat-generating component and the second heat spreader.

4. The apparatus of claim 1 , further comprising:
an actuator operable to move the heat-transfer pipe and the heat spreader between the first configuration and the second configuration.

5. The apparatus of claim 4 , further comprising:
a component configured to couple to the housing, wherein the component comprises an activation element configured to activate the actuator based on proximity between the housing and the component.

6. The apparatus of claim 5 , further comprising:
a sensor operable to detect whether the component is attached to the housing.

7. The apparatus of claim 6 , wherein the heat-generating component is operable increasing its clock rate based on the sensor detecting that the component is attached to the housing.

8. The apparatus of claim 1 , wherein the gap is configured to break a path of thermal conductivity between the heat spreader and the portion of the housing.

9. The apparatus of claim 8 , wherein, in the second configuration, the heat spreader connects the path of thermal conductivity between the heat spreader and the portion of the housing.

10. A system comprising:
a housing forming a cavity;
a heat-generating component within the cavity;
a heat spreader operable to distribute heat over a portion of the housing; and
a heat-transfer pipe pivotally coupled to the heat-generating component and the heat spreader, the heat-transfer pipe operable to transfer heat from the heat-generating component to the heat spreader, wherein the heat-transfer pipe and the heat spreader are movable between a first configuration and a second configuration, wherein:
in the first configuration, a gap separates the heat spreader and the portion of the housing based on the heat-transfer pipe being at a first orientation, and
in the second configuration, the heat spreader closes the gap and is thermally coupled to the portion of the housing based on the heat-transfer pipe being at a second orientation.

11. The system of claim 10 , wherein the heat-transfer pipe comprises at least
one bend forming continuous, noncollinear portions of the heat-transfer pipe.

12. The system of claim 10 , wherein the heat-transfer pipe is a first heat-transfer pipe and the heat spreader is a first heat spreader, and further comprising:
a second heat-transfer pipe and a second heat spreader, wherein the second heat-transfer pipe is pivotally coupled to the heat-generating component and the second heat spreader.

13. The system of claim 10 , further comprising:
an actuator operable to move the heat-transfer pipe and the heat spreader between the first configuration and the second configuration.

14. The system of claim 13 , further comprising:
a component configured to couple to the housing, wherein the component comprises an activation element configured to activate the actuator based on proximity between the housing and the component.

15. The system of claim 14 , further comprising:
a sensor operable to detect whether the component is attached to the housing.

16. The system of claim 15 , wherein the heat-generating component is operable increasing its clock rate based on the sensor detecting that the component is attached to the housing.

17. The system of claim 10 , wherein the gap is configured to break a path of thermal conductivity between the heat spreader and the portion of the housing.

18. The system of claim 17 , wherein, in the second configuration, the heat spreader connects the path of thermal conductivity between the heat spreader and the portion of the housing.
