On the optimal design of multistage thermoelectric coolers

摘要

We perform optimal designs of two applicable configurations of multistage thermoelectric (TE) coolers, with serial and separate electric currents flowing through each stage, respectively. The finite-rate heat transfers between the coolers and reservoirs are taken into account. A general optimization method is developed, with which the cooling power and coefficient of performance (COP) for the two types of TE cooler can be maximized, respectively. The optimal design parameters are numerically calculated with reference to commercially available TE materials.
