With the increasing miniaturization and performance demands of modern electronic systems, the challenge of effective thermal management has become more critical than ever. Passive cooling strategies, particularly pin fin heat sinks, offer promising solutions due to their high surface area and compact structure. However, traditional geometries such as cylindrical and square fins often under perform under high heat flux conditions due to limitations in flow interaction, boundary layer disruption, and thermal distribution. To address these limitations, this study presents a comprehensive computat...
With the increasing miniaturization and performance demands of modern electronic systems, the challenge of effective thermal management has become more critical than ever. Passive cooling strategies, particularly pin fin heat sinks, offer promising solutions due to their high surface area and compact structure. However, traditional geometries such as cylindrical and square fins often under perform under high heat flux conditions due to limitations in flow interaction, boundary layer disruption, and thermal distribution. To address these limitations, this study presents a comprehensive computational fluid dynamics (CFD) investigation into the effects of geometric modifications, namely shape variation, twisting, and perforation, on the thermal and fluid flow behavior of a novel heat sink design.
