Abstract

Heat sink optimization aims to improve hydrothermal characteristics, minimize weight, and reduce costs. This paper reviews some theoretical, numerical, and experimental studies dealing with the optimization design of fins and heat sinks of different shapes from 1958 to 2023. In the theoretical aspect, one-dimensional conduction heat transfer equations are derived to determine the optimum dimensions of rectangular, triangular, and spine fins, which involve circular, conical, concave, and convex fins. While the numerical studies dealt with heat sink optimization using design parameters such as fin dimensions, number of fins, fin arrangements, inclined angle, performing fins with different shapes, and flow rate ranges. Additionally, experimental studies were carried out in order to investigate optimizing heat sinks in a similar manner to numerical studies. Some of these studies suggested empirical correlations that could be used to compute Nu number and friction factors, assisting the designer in planning a preliminary heat sink design.
