NUMERICAL INVESTIGATION ON HEAT SINK BY COMPUTATIONAL FLUID DYNAMICS (CFD)

Abstract

The forced-air cooling technique, one of the effective methods for thermal management of electronic equipment cooling, is commonly used in a conventional-size heat sink. Conventional or mini sized heat sinks are commonly used in many industrial applications as cooling devices, because of their easy serviceability, high reliability, simplicity in the mechanism of heat transfer and ease of testing. In this paper heat sink is designed and investigated for different velocity variation at the inlet to select appropriate fan to cool the heat sink and also effect of ambient conditions on the heat sink are studied. Finally the results are compared with the Computational Fluid Dynamics software FLUENT.
