Abstract

Computer desktops have changed very much since the last decade. There are more demand in speed and thus in power. Since then, heat dissipation is one of the main concern when manufacturer's design. Usually finned heat sink is used to transfer the heat from the processor. When the heat travels through the heat sink heat is dissipated and thus helps the processor to keep cool. The heat sink plays a very important part in order to keep the efficiency and stable operation of the desktops. Most ofthe time when a desktop crashes it is because of overheating. Thus the task of selecting the best heat sink for a particular application from the hundreds of configurations available from the various manufacturers can be a formidable task for an engineer. In this research work, preliminary studies have been carried out for the performance improvement of a parallel-plate heat sink considering the various geometric parameters, such as number of fins, fin length, fin height, and base height. The modelling and simulation of the heat sink is carried out with Solidwork software. The results are analyzed using analysis of variance and response graphs.
