Claim 0:
1. An electronic device, comprising:
a first device housing having a first structure that is thermally conductive and generates thermal energy, the first device housing having a first chamber;
a second device housing having a second chamber with a heat spreader or heat sink as a second structure that is thermally conductive;
a hinge coupling the first device housing to the second device housing, the first device housing pivotable about the hinge relative to the second device housing; and
a flexible layer assembly extending through the first chamber and the second chamber with one segment extending through the hinge, the flexible layer assembly comprising:
a flexible circuit having a first end thermally coupled at a first location within the first device housing and a second end thermally coupled at a second location within the second device housing, the first chamber situated between the first location and the hinge, the second chamber situated between the second location and the hinge; and
a first thermal spreader layer positioned on a first surface of the flexible circuit and having a third end thermally coupled to the first structure within the first device housing and a fourth end thermally coupled to the second structure within the second device housing, the first thermal spreader layer 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 first structure comprises a battery assembly and a circuit board assembly that generate the thermal energy, the flexible layer assembly comprising the first thermal spreader layer thermally coupled to the battery assembly, and a second thermal spreader layer thermally coupled to the circuit board assembly;
the flexible layer assembly deforming 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.
