THERMOELECTRIC FINNING FOR PIPELINE Russian patent published in 2018 - IPC C23F13/00 

FIELD: energy.

SUBSTANCE: invention relates to heat and power engineering and can be used to generate electricity during transportation of various heat carriers in pipes. Thermoelectric finning comprises a pipeline section on which longitudinal ribs are arranged along its entire length, wherein the ribs consist of interconnected thermionic transducers made of different metals M1 and M2, ends of which are interconnected by welding or soldering, which along the entire length of the rib are closed laterally by strips made of mica and metal, forming the upper and lower edges of the ribs, free ends of each pair of ribs at both ends in the cooling zone are connected by bridges and capacitors, forming thermoelectric sections connected together by capacitors as well, wherein the outer surface of all component rib elements is covered with a layer of hydro-resistant dielectric material, lower edges of the ribs of the thermoelectric sections are pressed in the heating zone against the surface of the pipeline, the upper edges of the ribs of the thermoelectric sections are located in the cooling zone in the environment, outer capacitors of the outer thermoelectric sections are equipped with current leads with the same charges, and at the boundaries of the pipeline section the ends of the lower edges of the ribs of the thermoelectric sections are pressed against the surface of the pipeline by two clamps.

EFFECT: increased reliability and efficiency of thermoelectric finning.
