Abstract

In this paper, Numerical simulation of the convection heat transfer in Micro-channel Heat sinks with air working fluid is investigated. The main objective of this research is to study the effect of geometric parameters of the fin, including diameter, distance between fins and fins height, as well as the inlet fluid flow velocity on the average temperature fins, average temperature of fluid at outlet, temperature distribution in longitudinal direction of the Micro-channel and heat flux passing fins. For this purpose, the cooling fluid flow passing through a Micro-channel Heat sinks with bar fins which have the elliptical cross-section and placed in a linear arrangement is simulated using a finite volume method. The incompressible, laminar, steady, and single-phase fluid flow is considered, and the radiation heat transfer, free convection and the body forces are neglected. Simulation results indicate that changes in diameter and distance between the fins as well as the velocity of the inlet fluid have a significant effect on the heat transfer rate of the Heat sink, but the temperature variations due to the change in the height of the fins are low.
