THERMOELECTRIC GENERATOR FOR HEAT SUPPLY SYSTEM Russian patent published in 2020 - IPC F25B21/02 F24H1/30 

FIELD: heat power engineering.

SUBSTANCE: invention relates to heat engineering, namely to heat supply systems for residential, public and industrial buildings. Thermoelectric generator includes a section of the supply pipeline and two thermoelectric units located around its external surface and connected by electric wiring to the inverter, accumulator and consumers of thermoelectricity. Each thermoelectric unit consists of N thermoelectric sections located along the perimeter of the pipeline surface, pressed to each other. Each section is a longitudinal frame with n rectangular openings, in which rubber gaskets are laid with their lower edges n flat thermoelectric converters connected by terminals with similar collectors. Cavity between inner surface of flat thermoelectric converters, frames and outer surface of pipeline is filled with dielectric granular material with high heat engineering properties. Radiators pressed to outer surface of flat thermoelectric transducers by fastening bolts are applied on upper outer surface of flat thermoelectric transducers of each frame of thermoelectric sections. Thermoelectric sections are closed by a cylindrical casing with an annular header connected from above to a vertical exhaust pipe, inside of which there is an exhaust fan.

EFFECT: increased efficiency of thermal electric generator for heat supply system.
