THERMOELECTRIC POWER GENERATION DEVICE AND THERMOELECTRIC POWER GENERATION SYSTEM Russian patent published in 2020 - IPC H01L35/28 

FIELD: physics.

SUBSTANCE: invention relates to thermoelectric power generation device. Said technical result is achieved due to that thermoelectric power generation device comprises thermoelectric elements having their first sides provided for heating units (3) and their second sides provided for cooling units; thermoelectric elements are provided on both sides of heating unit (3); cooling units are provided on both sides of heating unit (3) so that they face each other through thermoelectric elements, heating unit (3) is connected to heat exchange pipe (6) located in channel (5), in which high-temperature fluid medium flows; heat exchange pipe (6) has multiple tubular elements (61), and a plurality of bent sections (62) connecting tubular elements (61) to each other; in inner space (7a) of heating unit (3) heat carrier channels are formed so that heat carrier is distributed over heating surface of thermoelectric elements; heat carrier is evaporated in inner space (7b) of heat exchange pipe (6), and heat carrier phase changes: it is converted from liquid into steam, which is released from open end section (63) in high position of heat exchange pipe (6) into heat carrier channel in inner space (7a) of heating unit (3); condensed heat carrier flows from open end section (64) in low position of heat exchange pipe (6) into heat carrier channel in inner space (7b) of heat exchange pipe (6).

EFFECT: technical result is higher efficiency of power generation.
