Abstract
It is shown that the Peltier heat, previously regarded as a purely contact characteristic, must be included in the equation describing the heat-flux balance in the volume of a sample (simplified Ioffe-Stil’bans equation). Analytical expressions for the temperature distribution in a loaded thermocouple, which describe the main deviations from the linear distribution, are derived by a self-consistent calculation allowing for a temperature dependence of the Peltier heat. Equations which extend the Ioffe relations to the case of large temperature differentials and large heat fluxes are obtained for the efficiency of a thermocouple.
