Özet
his study presents the numerical design and optimization of a conformal liquid-based Battery Thermal Management System (BTMS) for cylindrical lithium-ion modules. The proposed circular cooling block integrates conformal channels that adapt to the cell arrangement, enhancing heat transfer and minimizing temperature gradients. A hybrid framework combining Computational Fluid Dynamics (CFD), Taguchi-based experimental design, and Genetic Algorithm (GA) optimization was applied to determine optimal geometric parameters. Four channel variables were analyzed across sixteen configurations, and results were processed through a deep-learning-based surrogate model to accelerate multi-objective optimization. The optimal design achieved a maximum cell temperature of 33.9 C, a temperature difference of 5.5 C, and a pressure drop of 528 Pa under 7C discharge conditions. Compared with conventional layouts, the proposed system improved cooling uniformity and reduced hydraulic losses. The findings demonstrate that conformal cooling geometries offer an effective path toward compact and energy-efficient BTMS designs for high-power electric vehicle applications.
