The Thermoelectric Cooler (TEC) is an environmentally friendly solid-state cooling technology with wide application potential. This study aims to analyze the effect of voltage variation on the thermal performance of a TEC-based cooling system applied to a prototype cooling box. The methodology involved designing a system with eight symmetrically installed TEC units, tested at five voltage levels: 16 V, 18 V, 20 V, 22 V, and 24 V. Evaluated parameters included cold and hot side temperatures, heat absorbed (Qc), and Coefficient of Performance (COP). Experimental results revealed that increasing voltage up to 22 V significantly enhanced system efficiency, with the highest COP of 0.25 and maximum Qc of 5.24 W. However, at 24 V, performance declined due to excessive heat accumulation on the hot side of the TEC, exceeding heat dissipation capacity. In conclusion, an optimal input voltage of 22 V was identified to yield the most efficient cooling performance. These findings support the applicability of TEC technology for compact and sustainable cooling systems.

The study successfully analyzed the impact of electrical voltage on a TEC-based cooling system.Results indicated that increasing voltage up to 22V improved system efficiency, achieving a peak COP of 0.25 and maximum heat absorption of 5.Beyond 22V, performance decreased due to excessive heat buildup on the TECs hot side, highlighting an optimal operating voltage for maximizing cooling performance.

Further research should investigate the long-term stability and reliability of TEC systems under varying load conditions and environmental factors to ensure their durability in real-world applications. Exploring advanced heat sink designs and incorporating phase change materials could enhance heat dissipation capabilities, potentially overcoming the limitations observed at higher voltages and improving overall system efficiency. Additionally, a comprehensive economic analysis comparing TEC cooling systems with conventional refrigeration technologies is needed to assess their cost-effectiveness and identify potential market niches where TECs offer a competitive advantage, considering both initial investment and operational expenses. These investigations will contribute to a more holistic understanding of TEC technology and facilitate its wider adoption in diverse cooling applications, ultimately promoting sustainable and energy-efficient solutions.
