THERMOELECTRIC DEVICE FOR POWER GENERATION Russian patent published in 2020 - IPC F02G5/02 H01L35/00 H02N11/00 

FIELD: electricity.

SUBSTANCE: thermoelectric device for electric power generation (1A) includes thermoelectric element (2) having a first side provided outside of heating device (3), and a second side provided on cooling device (4), and heat transfer tube (6) located in channel (5), in which high-temperature heat carrier flows. Heating device (3) and heat transfer tube (6) have inner spaces (9a, 9b) communicating with each other. Inner space (9a) of heating device (3) and inner space (9b) of heat transfer pipe (6) form circulation channel (9), in which heat carrier circulates. Outlet (6b) of heat transfer pipe (6), from which heat carrier flows, is provided in position higher than inlet (6a) of heat transfer tube (6), into which heat carrier flows. Input (6a) of heat transfer tube (6) is provided in position lower than the lowest end part of thermoelectric element (2). Heat transfer pipe (6) evaporates heat carrier flowing in circulation channel (9) using heat of high-temperature heat carrier. Heating device (3) condenses evaporated heat carrier.

EFFECT: technical result is higher efficiency of electric power generation.
