METHOD FOR MANUFACTURE OF SEMICONDUCTOR PATHS FOR THERMOELECTRIC MODULE AND THERMOELECTRIC MODULE ITSELF Russian patent published in 2014 - IPC H01L35/32 H01L35/34 

FIELD: electricity.

SUBSTANCE: invention refers to thermoelectric devices. The invention concept is as follows: the method includes manufacturing of rods of thermoelectric material by hot extrusion. Thereafter lateral side of rods is treated. Water paint compound with fluorine rubber is applied to the rod lateral sides by means of cathodic or anodic electrodeposition in order to obtain a protective polymer coating. Then the rods are washed and cured thermally. The rods are cut in order to obtain semiconductor paths of the preset length. Antidiffusion metal coating is applied to butt ends of the obtained semiconductor paths so that the edge touches the protective polymer coating without crossing it. The single- or multi-cascade thermoelectric module contains semiconductor paths of N- and P-conductivity so that they are located in parallel and do not tough each other. Semiconductor paths of N- and P-conductivity are manufactured as per the method specified above.

EFFECT: improving chemical, thermal and mechanical resistivity, providing high adhesion and elasticity for polymer coating of thermoelectric paths.
