“HEAT TRANSFER ANALAYSIS AND OPTIMIZATIION OF FINS BY VARIATION IN GEOMETRY”

Abstract: This paper explores the thermal performance and geometric optimization of extended surfaces (fins) in heat dissipation applications. By evaluating various geometries—including rectangular, triangular, parabolic, and pin fins— we analyze the trade-offs between heat transfer rates and material volume. Modern optimization techniques, such as Random Forest metamodels and multi-fidelity evolutionary algorithms, are discussed as means to reduce material consumption while maintaining thermal reliability. Key findings indicate that while rectangular fins provide high absolute heat flux, triangular and parabolic profiles offer superior material efficiency. Numerical studies show that intelligent optimization can reduce heat sink volume by up to 26% with minimal temperature penalties (Sun et al., 2025).
