Patent ID: 8283613

Claim:
A heat-pipe electric-power generating device, suitable for converting heat energy or heat source energy into electrical energy, comprising: a heat pipe, wherein the heat pipe has a sealed interior space capable of producing a steam flow from an evaporating end to a condensing end through a pressure difference between the ends of the heat pipe, wherein the heat pipe comprises: an outer wall, of which the evaporating end directly contacts with an external heat source; and an inner wall of capillary material, disposed on the outer wall from inside for capillary transporting a liquid condensed at the condensing end to the evaporating end; a steam-flow electric-power generating device, having a rotating portion and a fixed portion disposed on the heat pipe, wherein the rotating portion is driven by the steam flow to generate an electric power, wherein the rotating portion comprises a rotating magnet and the fixed portion comprises a plurality of magnet blocks separately disposed over the heat pipe and a winding respectively surrounding each of the magnet blocks; a sleeve, disposed with directly contacting and fixing between the inner wall of capillary material and the steam-flow electric-power generating device, wherein the sleeve at a middle section of the heat pipe prevents the steam flow from condensing on the inner wall of capillary material at a section giving the sleeve in contact; and an electrode structure, coupled to the steam-flow electric-power generating device for leading the electric power out.
