Abstract :

Today scenario is to use handy electronic devices if motivates the study of cooling devices for controlling temperature and extracting heat which will increase the reliability of components. The continuing increase of power densities in electronics packages and the simultaneous drive to reduce the size and weight of electronic products have led to an increased importance on thermal management issues in this industry. Plate fin heat sinks are commonly used devices for enhancing heat transfer in electronics components. The choice of an optimal heat sink depends on a number of geometric parameters such as fin height, fin length, fin thickness, number of fins, base plate thickness, space between fins, fin shape or profile, material etc. Given a set of design constraints, one needs to determine the maximum possible performance of a heat sink within the constraints. Optimizing the above parameters to achieve low thermal resistance and low pressure drop is very difficult. In order to select the optimal geometric parameters of a heat sink for a more design tools to predict heat sink performance. Therefore in this research work, to select an optimal heat sink design, preliminary studies on the fluid flow and heat transfer characteristics of a parallel plate heat sink have been carried through CFD modelling and simulations. The simulation is carried out with a commercial package provided by Fluent Inc. The geometric parameters considered in this study are fin height, fin thickness, base height and fin count. Experimental validation of simulation results also has been performed. In this present study, for thec100W heat input the heat sink of the size width at 0.5m, length at 1m is used. For parametric study concludes that for minimum thermal resistance the geometric parameters.
