A magnetic substance is disposed on the fan to form a magnetic field. A stator coil of a generator is disposed at the outer of the heat-pipe, which is corresponding to the position of the fan.

Further, the heat-pipe electric power generating device can be applied on a hydrogen/oxygen gas generating apparatus and an internal combustion engine system of a motor vehicle.
