Abstract
A technique for increasing the thermal capability of a portable electronic device includes transferring dissipated heat from a heat source disposed within the portable electronic device to at least one heat exchanger via at least one respective thermal transfer device. This may be in addition to another heat exchanger connected to the heat source via another thermal transfer device. At least one external fan is disposed adjacent to the at least one heat exchanger and dissipated heat transferred from the heat source to the at least one heat exchanger is removed via a flow of air generated by the at least one external fan. This may be in addition to an internal fan disposed adjacent the another heat exchanger to dissipate heat transferred from the heat source to the anther heat exchanger via flow of air generated by the internal fan. The at least one thermal transfer device may be a heat pipe. The portable electronic device may be a notebook computer and the heat source disposed therein may be a processor.
