Multi-objective CFD optimization of plate-fin heat sinks via fin morphology and perforations

This study investigates the optimization of rectangular plate-fin heatsinks for enhanced thermal and flow performance using numerical simulations. Four innovative configurations: Bifurcated Longitudinal Split Fins (BLSF), Variable Height Gradient Fins (VHGF), Hybrid Plate-Pin Fins (HPPF), and Perforated Plate Fins (PPF) are developed and analyzed. Results demonstrate that the HPPF achieves superior thermal performance due to its hybrid plate-pin design, while the PPF excels in hydraulic efficiency through reduced pressure drop. The BLSF and VHGF configurations offer balanced performance for applications prioritizing thermal dissipation and moderate pumping power constraints. These findings provide a framework for selecting heatsink designs tailored to specific cooling requirements, advancing the development of efficient thermal management systems for electronics and photovoltaic cooling applications.
