Abstract: The invention relates to thermoelectric devices and can be used in a variety of devices which utilize thermoelectric modules. A thermoelectric module containing n and p-type conductivity semiconducting branches, connected by means of switching buses into an electric circuit, and a protective polymer coating. The protective polymer coating is applied to the interconnected branches and buses, and the coating is an electrodepositable polymer varnish-paint composition modified with a fluoroelastomer latex.

Abstract: The claimed invention can be used for the manufacturing of thermoelectric modules. The method includes the manufacturing of rods from a thermoelectric material by a hot extrusion method. Then, the side surface of the rods is preliminarily treated. Then, a water-based paint system with fluorine rubber is applied on the side surface of the rods by a cathode or anode electrodeposition method and a protective polymeric coating is produced. Then, the rods are washed and thermally cured. The rods are cut and semiconductor branches of a specified length are produced. After that, an antidiffusion metallic coating is applied on the face surfaces of the produced semiconductor branches so that the edge is in contact with the protective polymeric coating without crossing it. The claimed process enable an improvement in the chemical, thermal, and mechanical resistance and provision of a high adhesion and plasticity of the polymeric coating of the thermoelectric branches.
