Abstract
This research provides a comprehensive analysis of thermoelectric
coolers (TECs), emphasizing performance enhancement through optimization
techniques. The study focuses on improving key metrics, including the
Coefficient of Performance (COP), energy efficiency (ηI\eta_IηI), and exergy
efficiency (ηII\eta_{II}ηII), which are crucial for evaluating TEC
functionality. A single-objective optimization framework was formulated to
maximize these parameters using a genetic algorithm (GA), an advanced
optimization technique well-suited for handling non-linear, multi-variable
systems. The optimization process identified critical design parameters, such
as thermoelectric element length, cross-sectional area, and input current, that
significantly impact TEC performance. Validation of the optimization findings
was carried out using finite element simulations in the ANSYS® thermal-electric
module, which incorporated realistic conditions such as thermal resistance and
electrical contact resistance. The close agreement between the analytical
results derived from GA and the numerical results from FEM simulations, with
deviations below 2%, underscores the robustness of the proposed methodology.
This integration of optimization and simulation provides a reliable framework
for evaluating and refining TEC designs. The study also highlights the pivotal
role of thermoelectric material properties, particularly the figure of merit
(ZT), in advancing TEC performance. Enhancements in ZT, achieved through
innovations like nanostructuring and material doping, can reduce thermal
conductivity while maintaining high electrical conductivity and Seebeck
coefficients, further boosting TEC efficiency. Additionally, the interplay of
thermal and electrical resistances was identified as a key factor influencing
heat transfer and overall system efficiency. These findings emphasize the
importance of sustainable TEC designs to minimize energy consumption and reduce
environmental impact, offering a green alternative to conventional
refrigeration systems. By leveraging advanced materials and optimization
strategies, TECs have the potential to revolutionize energy-efficient cooling
technologies, with applications in electronics cooling, medical refrigeration,
and renewable energy systems.
