Computational Study of the Effect of Fin Longitudinal Spacing and Reynolds Number on the Performance of Oblique Heat Sinks

Abstract

Various heat sinks have been widely researched to get a better performance design. This research aims to study the effect of fin longitudinal spacing and Reynolds number on heat sink performance at an oblique angle of 45 degrees. This study utilizes a finite-volume computational approach to determine the performance and details of the flow on the heat sinks. The calculations are conducted on fin spacing between 0.3 mm and 1.5 mm in the Reynolds number of 6,470 to 19,410. It was found that the fin longitudinal spacing significantly affects the performance of heat sinks for various Reynolds numbers, where the larger the spacing, the higher the Nusselt number. Based on this study, it can be concluded that it is necessary to determine the optimal fin longitudinal spacing in the design of the oblique heat sink.
