Claim 13:
14. A method, comprising:
assembling a first thermal spreader layer positioned on a first surface of a flexible circuit to form a flexible layer assembly;
extending the flexible layer assembly through a hinge;
coupling the hinge between a first device housing and a second device housing, the first device housing pivotable about the hinge relative to the second device housing, the first device housing has a first chamber adjacent to one side of the hinge and the second device housing having a second chamber adjacent to an opposite side of the hinge;
fixedly coupling a first end of the flexible circuit to a first location in a first device housing;
thermally coupling a third end of the thermal spreader layer to a first structure of the first device housing, the first structure being thermally conductive and generating thermal energy;
wherein the first structure comprises a battery assembly and a circuit board assembly that generate the thermal energy, and the method further comprises thermally coupling the first thermal spreader layer to the battery assembly, and thermally coupling a second thermal spreader layer to the circuit board assembly; and
thermally coupling a fourth end of the thermal spreader layer to a heat spreader or heat sink within the second chamber, the heat spreader or heat sink providing a second structure of the second device housing that is thermally conductive and used for transferring thermal energy from the first structure that generates thermal energy to the second structure that is the heat spreader or heat sink;
wherein the flexible layer assembly deforms to a deformed state within one or both of the first chamber or the second chamber when the first device housing and the second device housing pivot about the hinge from a closed position to an axially displaced open position.
