Abstract

In this paper a fluid flow and thermal characteristics of micro pin fin heat sink is investigated with the computational fluid dynamics, by this with three fins geometries (square, triangular and circular) and Nano fluids is used as a cooling fluid, since the flow and heat transfer have been studied with two types of Nano fluids (Diamond-water and Alumina-water) in addition to the base fluid water. The results obtained indicated that, using of Nano fluids instead of water as a coolant leads to enhanced heat transfer performance Also performance of heat sink is good. Here for the analysis of heat sink, the model has been designed in the CATIA V5 software, and for the fluid flow and numerical analysis ANSYS FLUENT 16.2 software is used.
