Abstract
A heat-dissipation method comprises providing a heat-transfer module and a heat-dissipation module, wherein the heat-transfer module is disposed in a portable electronic device, and the heat-dissipation module is disposed in a battery charger. The heat-dissipation module then contacts the heat-transfer module to remove heat from the electronic device via conduction. Finally, the heat-dissipation module dissipates heat via conduction or convection.
