Modélisation analytique 3D d’un dissipateur de chaleur à ailettes à plaques

Abstract

High-performance cooling is an essential requirement for modern microprocessors that generate large amounts of non-uniform heat distribution. Heat sinks have traditionally been used for thermal management. In this study, the effects of certain design parameters on the performance of the flat plate heat sink were analyzed. Heat transfer simulations were performed using ABAQUS finite element analysis software to understand the variation in heat flux and temperature of the heat sink. Three parameters were varied: the number of fins, the heat flux and the material of the heat sink, and a comparison of the heat flux distribution and temperature between the full-finned, Rectangular and perforated heat sink was made. In the end, the results were discussed.
