Optimization Methodology of Thermoelectric Peltier-Modules, for Structural Design and Material Selection, using MCDM and FEM Modelling

Abstract

Monitoring the temperature of medical products is essential, to ensure their safety and stability. The thermoelectric Peltier-modules can be used for either cooling or heating in this application. In this work, different geometries are applied and the resulting performance of the Bi2Te3-based module, characterized via finite element simulations and materials, is analyzed, where the primary objective was to reduce shear and torque stresses, which also depends operating conditions. In the first phase, Finite Element Analysis (FEM) analysis of the thermo-mechanical test unit for the Peltier-modules, is conducted. In the second phase, the best design concept selection phase, using multi-criteria decision theory is introduced, where the ranking of the criteria is weighted by the characteristics assigned to the selected values. The object is to choose the best design concept, from the alternatives generated during the first phase.
