Abstract

This article describes the process of modeling the influence of changes in electric current density in the branches of a thermoelectric generator on the processes of heat conversion in its volume. For this purpose Comsol Multiphysics software was used. Using the program, changes in the distribution of heat and temperature inside thermocouples with varying current density were analyzed. This is an important parameter for optimizing the efficiency of thermoelectric generators. The article also explains the processes of establishing electric currents in thermopile components, the phenomenon of heat transfer in solids, the thermoelectric effect, electromagnetic heat source, the limits of the thermoelectric effect and temperature coupling.
