Özet

In this study, the thermalhydraulic performance of solid (0P) and three-perforated (3P) cylindrical pin-fin heatsinks under forced convection was numerically investigated using CFD with the k-ω SST turbulence model (Re = 3509– 6586). Validation against reference data showed pressure drop agreement within 10%. Results demonstrate that the 3P pin-fin structure achieves 4–5°C lower surface temperature than the solid pin at equivalent fan power
