Abstract
This article has as main objective to make a numerical analysis of the size relation that two different types of sets of heat dissipation can work in a forced convection environment. The first set, which will be called Model 1, is composed of a heat sink and an integrated circuit. The second set (Model 2) is composed of a heat sink, vapor chamber and integrated circuit.The numerical analysis will allow the user to verify which greater heat sink can be used effectively in each case. For the accomplishment of this work, a simple thermal resistors model was constructed using ANSYS Fluent software, student license, as computational fluid dynamics tool, represented by blocks with fixed thermal properties, modifying only the dimensions. The results demonstrate the behavior of the temperature in the heatsink and integrated circuit of each model and prove that the vapor chamber evenly distributes heat in the heat sink, decreasing the temperature of the electronic component
