Abstract:
A thermal dissipation subassembly for an electronic device, said thermal dissipation subassembly comprising:a thermal spreader having a main surface thermally coupled to a surface of a heat generating component, said main surface of said thermal spreader having a larger surface area than a surface area of said surface of said heat generating component, said heat generating component having a non-uniform thermal distribution across said surface between at least one first region of said surface and at least one second region of said surface, wherein said at least one first region has higher heat flux than said at least one second region; and at least one thermoelectric device comprising a discrete device having a plurality of thermoelectric couples, said at least one thermoelectric device also having a cooling surface with a smaller surface area than the surface area of said surface of the heat generating component, and wherein said cooling surface of said at least one thermoelectric device is similarly sized as or is smaller than said at least one first region and is positioned over said at least one first region having said higher heat flux to facilitate dissipation of said higher heat flux.
