THERMOELECTRIC CHARGING DEVICE FOR GADGETS Russian patent published in 2018 - IPC H01L35/32 

FIELD: electricity.

SUBSTANCE: thermoelectric charger for gadgets contains a body, made of dielectric material with high thermal conductivity, with parallel fins on opposite sides, forming grooves, where inside the fins there are U-shaped rows, made as fiberglass strips, the surface of paired perpendicular lengths, which are alternately covered with foil of different metals M1 and M2, their ends are bent at an angle of 90°, interconnected and also covered with two metal foil layers M1 and M2 respectively, forming separate thermos emission elements. The bent ends of the paired perpendicular lengths are placed on the opposite sides of the parallel fins parallel to their end face and covered with a layer of the dielectric material, the extreme perpendicular lengths of each row, next but one, are interconnected by bridges, the extreme perpendicular lengths of the extreme U-shaped rows are connected with single-pole collectors, which are, in turn, connected to the converter and storage battery and in the grooves a grid, consisting of a frame with longitudinal stripes, is located in the grooves. It inverts the grooves of the body, made of a material with high thermal conductivity.

EFFECT: increasing the efficiency of the charge, along with obtaining electric power, reduction of the consumption of metals for the manufacture of thermos emission elements, and simplification of their manufacture and significant reduction of the weight of the device.
