Numerical Investigation of Heat Transfer Characteristics on Differential Square Fin Heat Sinks

Year 2022, Volume: 6 Issue: 1, 76 - 81, 15.07.2022

Abstract

In this study, the temperature distribution on the square fin heat sink with differential fin distribution was numerically investigated. Numerical analysis was performed with ANSYS-Fluent package program and k-Ɛ turbulence model. The heat transfer performance realized on fixed nozzle-heat sink distance (35 mm) and three different Reynolds numbers (4000-8000-12000) on heat sinks with fins and plane surfaces were examined. Air at 20Cwas used as the fluid and 1000 W/m2 heat flux applied to the heat sink. In the study, temperature contours showing the temperature distribution on the heat sink and streamline images in which the turbulence formation caused by the fins on the heat sink surface were observed. As a result, it was determined that the differential square fins cause a more homogeneous temperature distribution on the heat sink compared to the plane plate. The heat transfer coefficient from the heat sink surface was determined as h=159,3 W/m2K at the highest Reynolds number. The Nusselt number does not increase much with the increase of the Reynolds number in the differential fins.
