High-temperature-difference annular segmented thermoelectric material generator and radial equal-sectional-area thermocouple unit thereof

The utility model relates to a thermoelectric power generation device. The utility model discloses a thermocouple unit of an annular thermoelectric material generator. The thermoelectric material support comprises p-type and n-type thermoelectric material support legs, the p-type thermoelectric material supporting legs and the n-type thermoelectric material supporting legs are each of a segmentedstructure. High-conductivity metal connecting sheets/electrodes are used for connection; two end faces of the thermocouple unit are concentric arc end faces. Theta is used as a circumferential included angle of the thermoelectric material supporting leg; r1 and r2 are radial distances from the circle center of the cylindrical heat source to the upper ends and the lower ends of the thermoelectric material supporting legs respectively, the radial widths and radiuses of the p-type thermoelectric material supporting legs and the n-type thermoelectric material supporting legs in the thermocouple units are in direct proport
