COMPACT THERMAL ALTERNATOR Russian patent published in 2018 - IPC H01L35/02 

FIELD: power engineering.

SUBSTANCE: use for the transformation of thermal energy into electricity when the electricity supply is absent. Essence of the invention is about the compact thermal alternator comprises a top flanged housing, closed by a removable clamping lid made of a dielectric material with a high thermal conductivity, in the holes of the lid and the threaded holes of the housing there are clamping bolts, the removable pressure cover is provided at opposite ends with pole collectors, inside the body parallel to its ends plates, made of a dielectric material with a low thermal conductivity, are vertically mounted, the opposite surfaces of each are alternately covered with Z-shaped stripes of foils of different metals M1 and M2, respectively, so that the upper horizontal ends of the metal strips M1 and M2 of one plate are pressed to the upper end of this plate, forming a separate thermionic converter, and the lower horizontal ends of these strips were pressed together with the horizontal ends of the previous and subsequent strips of metal foils M1 and M2 to the lower ends of the previous and subsequent plates, forming the previous and subsequent thermionic converters and thermoelectric section, the contact of the lower ends of the pole collectors with the ends of the Z-shaped bands of the upper and lower ends of the metal foil bands M1 and M2 of all thermionic converters is carried out by pressing the cover against the body by means of its vertical movement when the clamping bolts rotate.

EFFECT: provision of the possible efficiency increase of a compact thermal alternator.
