Heat-pipe electric-power generating device

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.
