Design and optimisation of heat sinks to enhance the thermal conductivity through simulations

Abstract

A Pin-Fin is a component of heat sink, in a thermal system that aids in the dissipation of heat produced. The efficiency of the system is determined in large part by the design of the pin fin. The goal of the study was to use the Taguchi method of optimization to construct a Pin-fin with certain geometry and analyse it using computational simulations. To study the numerous tests to be undertaken on the performance characteristics, an orthogonal array was used. Base Plate Thickness, Fin Height, Fin Width, and Fin Spacing were all considered when designing the heat sink's pin–fin. As a result, the L-9 orthogonal array was chosen, and testing was carried out using commercial simulation software. The simulation testing took place in a Steady-State environment. For efficiency, heat flux, and temperature difference V/s heat sink characteristics, the Signal to Noise ratio was shown. Various iterative trials were compared using the produced graphs and the temperature dissimilarity that exists between the base and the fin tip to determine the most optimum design. In comparison to the other models with inconsistent response characteristics, the study found that heat sink models with a mid-range of thermal efficiency proved to be of reliable design.
