Abstract

The inhomogeneous thermoelectric generator model considering inhomogeneous thermal conductivity and effect of heat transfer between thermoelectric generator and heat source is established. The general performance analysis of inhomogeneous thermoelectric generator is presented. The impacts of number of thermoelectric elements, heat conductance and temperature of high temperature source on performance characteristics of inhomogeneous thermoelectric generator are discussed. The results show that,compared with homogeneous thermoelectric generator, the maximum output power and maximum efficiency of the thermoelectric generator can be effectively improved due to the increase in the inhomogeneous degree of thermal conductivity. And the performance characteristics could be enhanced with higher number of thermoelectric elements, heat conductance or temperature of high temperature source.
