Abstract
A power supply module for a portable computer and a method of dissipating heat generated in the power supply module. The module comprises: (1) a circuit board having a plurality of power supply components mounted thereon, (2) a module electromagnetic shield at least partially surrounding the circuit board, the module electromagnetic shield electromagnetically shielding at least some of the plurality of power supply components, (3) metallic heat conduction paths, integrally disposed within the circuit board and substantially within a footprint of selected ones of the plurality of power supply components, for transferring heat from the selected ones of the plurality of power supply components through the circuit board and (4) compliant heat conduction pads, coupled between the circuit board and the module electromagnetic shield, for transferring the heat from the heat conduction paths to the module electromagnetic shield, the module electromagnetic shield dissipating the heat and thereby functioning as a heat sink, the heat conduction paths and heat conduction pads cooperating to form a compact structure for transferring heat from the selected ones of the plurality of power supply components to thereby reduce a required volume of the power supply module.
