Generator of electric energy based on the thermoelectric effect

摘要

A generator of electric energy based on the thermoelectric effect comprises a layer of thermoelectric material (1) set between two pipes (4, 5) that guide two flows of fluid (F1, F2) at temperatures different from one another. Each of said pipes (4, 5) has its wall in heat-conduction contact with the respective side of the layer of thermoelectric material (1), and its cavity of passage for the respective flow of fluid is occupied by a porous material (6) or is divided by diaphragms (4f, 5f) into a plurality of sub-channels (4e, 5e) so as to obtain a large heat-exchange surface between each flow of fluid (F1, F2) and the wall of the respective pipe (4, 5) and between said wall and the respective side (H, C) of the layer of thermoelectric material.
