Abstract:
1. A thermal dissipation and shielding system for an electronic device, comprising: an electronic device comprising an external surface and device components including a first component which comprises a heat source; a thermal solution comprising two major surfaces, the thermal solution positioned such that one of its major surfaces is in operative contact with the first component such that it is interposed between the first component and an external surface of the electronic device, wherein the thermal solution comprises at least one sheet of compressed particles of exfoliated graphite sandwiched between two outer layers, where the thermal function of the thermal solution, referred to as Fx, for each of the outer layers in combination with the at least one graphite sheet, is between about −10 and about +7, determined by the following formula: where Y 1 is the Young's modulus for one of the outer layers and Y 2 is the Young's modulus for the graphitic core; Thick 1 is the thickness in millimeters (mm) of the outer layer and Thick 2 is the thickness of the graphitic core; Tc 1 is the thermal conductivity of the outer layer and Tc 2 is the thermal conductivity of the at least one graphite sheet; and d 1 is the density of the outer layer and d 2 is the density of the at least one graphite sheet, and further wherein the graphitic core comprised of at least one sheet of compressed particles of exfoliated graphite and the two outer layers are molded or formed into a complex, non-planar shape such that they follow the contours of device components thereby reducing space consumed by the thermal solution in the electronic device.
