Micro thermoelectric cooler (μTEC) modules have recently attracted significant attention due to their compact size, effective heat dissipation, and rapid thermal response. These characteristics make them highly suitable for applications in electronics, telecommunications, and healthcare. The present study focuses on evaluating the cooling performance of a μTEC module under varying operating conditions. A comprehensive experimental setup was developed to measure critical parameters such as temperature difference, cooling capacity, and coefficient of performance (COP). Experimental results were compared with theoretical predictions, revealing a strong correlation, particularly at lower temperature differences and moderate current levels. However, deviations were observed at higher currents, primarily attributed to increased Joule heating and contact resistance. Overall, the agreement between experimental data and the theoretical model supports its validity while also highlighting areas for potential refinement. The findings contribute to a deeper understanding of μTEC efficiency and support future enhancements in thermoelectric cooling system design.
