Thermo-siphon type generator apparatus

A thermo-siphon type generator apparatus comprising:

• a vessel filled with a working medium containing a heat medium and a low boiling-point medium which are insoluble to each other, said vessel defining a lower evaporating section, an upper condensing section and a heat-insulated section between said evaporating and condensing sections;
• a turbine connected to a generator;
• a first passage means for introducing the vapor of said low-boiling-point medium generated in said evaporating section to said turbine;
• a second passage means for introducing the vapor from said turbine to said condensing section;
• said evaporating section including a space in which said heat medium flows downwardly, a vapor bubble pumping space and a third passage means in which the low-boiling-point medium liquid flows downwardly, said pumping space and said space in which the heat medium flows downwardly being communicated with each other at their upper ends and their lower ends, and said space in which said low-boiling point medium liquid flows downwardly being communicated with the lower end of the pumping space, said pumping space being adapted to generate, when heated, upward movement of vapor bubbles of said low-boiling-point medium thereby to forward the vapor of said medium to said turbine through said first passage means.
