Abstract
A heat-pipe electric-power generating device capable of converting thermal energy to electrical energy is provided. The device includes a heat pipe and the heat pipe has a sealed internal space that can produce a steam-flow from an evaporating end to a condensing end according to a pressure difference caused by a temperature difference between the ends. A steam-flow electric-power generating device has at least a rotating portion disposed in the internal space for generating electric power when driven by a steam-flow. An electrode structure is used for leading the electric power out. The heat pipe is maintained in a sealed condition. In addition, several heat-pipe electric-power generating devices can be arranged into an array to form a heat electric-power generator or disposed inside an apparatus with a heat source for recycling the conventional waste thermal energy into useful electrical energy.
