PURPOSE:To improve efficiency of power generation by providing a turbine inside a heat pipe and further providing a liquid phase hydraulic fluid passage, for forcing fluid to flow back from a heat pipe condensing part to an evaporating part which furnish said turbine with a backpressure, separately from a steam passage leading from the evaporating part to the turbine. CONSTITUTION:Configuration of a heat pipe is such that gas of noncondensing property such as air or the like is vacuum exhausted from the interior of a hermetically closed pipe 1 made of copper or the like and then hydraulic fluid 2 of condensing property is sealed in said pipe. Then a wick 3 made of very fine lines such as metal net, carbon fiber or the like is provided on the inner peripheral face of said pipe 1. The hermetically closed pipe 1 is vertically erected and fitted with a jacket 4, inside which high- temperature fluid 5 flows, at its lower end part as an evaporating part 6, while an axial turbine 7 for driving a generator 11 is provided in its upper part. Further, the upper side part of the hermetically closed pipe 1 above the axial turbine 7 and a part below the surface of the hydraulic fluid 2 on the evaporating part 6 side are put in communication with each other by means of a bypass pipe 12, and a condensing part 15 including a cooling jacket 13 is provided in the medium part of the pipe 12. |
