Abstract:
A heat sink comprises a base panel having a top surface and a bottom surface. A plurality of pin fins extend outwardly from the top surface and each fin has a cross-sectional configuration with two radiuses, a first radius and a second radius, wherein the first radius is larger than the second radius. The first and second radiuses are tangentially interconnected by intermediate portions, giving the pin fin cross-sectional configuration a raindrop shape, thereby generating low pressure drop across the heat sink by minimizing the drag force effects and maintaining large exposed surface area available for heat transfer.
