Numerical Analysis of Heat Transfer in Microchannel Heat Transfer in Microchannel Heat Sink using Flow Disruption

Abstract

Microchannel heat sink is a passive heat exchanger that transfers the heat generated by an electronic or a mechanical device to a fluid medium, often a liquid coolant, where it is dissipated away from the device, thereby allowing regulation of the device's temperature at optimum levels. It is widely used in computers that are used to cool central processing units or graphic processors. In order to achieve great heat transfer performance of microchannel heat sink, passive method are used in this research particularly the flow disruption and secondary channel. A three-dimensional computational fluid dynamic (CFD) was conducted to study the characteristic of fluid flow and heat transfer in proposed design of microchannel heat sink with secondary channel and rectangular ribs (MCHS-SCRR) This research is to develop and optimize the heat transfer performance in a microchannel heat sinks to get high Nusselt Number low friction factor and high performance factor by optimizing the geometry design a simulation using certain software such as SOLIDWORKS and ANSYS. The result compared to previous research in this field of study.
