    摘要: Battery life and cooling are improved in an electronic device. A thermoelectric module and phase change material module are placed near a heat source in an electronic device. The thermoelectric module and phase change material module insulate a surface to be cooled on the electronic device. The thermoelectric module generates an electrical current in response to a temperature differential at opposite surfaces on the thermoelectric module. The phase change material module enhances or limits the temperature differential seen at the thermoelectric module. The electrical current generated by the thermoelectric module is used to charge a battery of the electronic device.
