ABSTRACT:
A thermo-siphon type generator apparatus making use of a gravity-type heat pipe in which a working medium is cyclically evaporated and condensed. The apparatus has a closed vessel filled with the working fluid and defining a lower evaporating section, an upper condensing section and a heat-insulated section between the evaporating and condensing sections. A turbine connected to a generator is mounted in or on the closed vessel. A first passage is provided for introducing the vapor of the working fluid generated in the evaporating section to the turbine, while a second passage is adapted for introducing the vapor from the turbine to the condensing section. The evaporating section includes a reservoir chamber adapted to store the working fluid in liquid phase, and a vapor bubble pumping space communicated with the reservoir chamber and adapted to generate, when heated, upward movement of vapor bubbles of the working fluid thereby to forward the vapor of the working medium to the turbine through the first passage. A third passage is provided for returning the condensate liquid to the reservoir chamber.
