Abstract

In this paper, we study a thermoelement used to cool liquid or gas fluxes that pass through legs consisting of permeable segments of thermoelectric materials connected in series. Methods for theoretical calculations and optimization of the thermoelement’s energy characteristics are presented based on mathematical optimal control theory and computer design techniques. Computer design results are presented for the case when segmented materials based on Bi2Te3 are employed in the legs. The effect of the number of segments, contact resistance, and structural and thermophysical parameters on the thermoelement’s energy potential is studied under optimal conditions of electric current and air pumping velocity. The results demonstrate the existence of optimal operating conditions for which the coefficient of performance is increased by 10% to 30% and the specific cooling capacity by 10% to 20%.
