COMBUSTION HEAT POWERED PORTABLE ELECTRONIC DEVICE

摘要

A combustion heat powered portable electronic device. At least one thermoelectric module (103) is sandwiched between a hot block (123) heated by a combustion heat source (102) and a cold-side heat sink (104) and provides electric power to a portable electronic device (110) from the temperature difference. An electric circuit provides power for purposes of operating the portable electronic device (110) either directly or indirectly by charging a rechargeable battery (99) which in turn provides power to the electronic device. In a preferred embodiment the combustion heat source is a catalytic combustion unit. The hot block (123) and/or cold side heat sink (104) can be integrated into a single unit with the thermoelectric module. In a preferred embodiment the cold side heat sink (104) is cooled by fins cooled by air driven by a forced air fan (115) powered by the thermoelectric module (103).
