METHOD OF DIRECT CONVERSION OF THERMAL ENERGY INTO ELECTRIC ENERGY AND GENERATOR FOR ITS IMPLEMENTATION Russian patent published in 2008 - IPC H01J45/00 

FIELD: power engineering.

SUBSTANCE: invention is related to the field of direct conversion of thermal energy in electric energy. Method consists in the fact that for temperature stabilisation in zone of energy conversion heat transfer from moving heat carrier to heat emission elements is implemented with simultaneous heating of heat carrier through channel wall from its other more heated part, thermal emission elements are installed in leak-tight casing of thermal emission generator in the form of segments that create rings around the channel with heat carrier with the possibility to create screw trajectory during passage of heat carrier flow, which moves from the channel outlet along its external part in reverse direction in gaps between rings, movement continues until temperature of spent flow decreases below temperature of electrons heat emission. Generator represents leak-tight casing of cylindrical form with device of heat carrier flow inlet from external source and device of heat carrier spent flow outlet, inside the casing thermal emission elements are installed in the form of rings, which are assembled from separate segments and connected into single electric circuit.

EFFECT: increase of efficiency of thermal energy conversion in electric energy at the account of efficiency factor increase and reduction of thermal emission generator dimensions.
