Manufacturers need to determine the best geometries for thermoelectric coolers (TECs) achieve optimal performance. In this study, we employed COMSOL Multiphysics software simulate performance enhancement of Bi2Te3 TEC. The TEC is constructed with alumina (Al2O3), copper (Cu), and bismuth telluride (Bi2Te3) materials. particular, Al2O3 acts as an electric insulator top bottom layers, Cu functions a conductor, serves p- n-type (TE) legs between layers. study examined how different TE leg heights (1.5 mm, 2 2.5 mm) shapes (square rectangular) affected TEC's It looked at various factors, such temperature gradient, potential, normalized current density, total net energy rate. Additionally, thickness effects insulator, pitch have also been investigated. According obtained results, it has determined that square type geometry provided among tested geometries, recommended its be 1.00 mm × 1.5 0.375 0.125 Cu, 0.50 they are expected yield satisfactory research involved obtaining parameters 18 elements utilized in fabrication TEC-simulated results revealed following metrics: ΔTmax = 73.94 K, Umax 2.52 V, Imax 3.00 A, Qmax 4.42 W, R 0.84 Ω, Z 0.002377 1/K.
