Heat transfer augmentation by using different techniques in small scale channels: A review study

Abstract

This paper highlights the most significant recent developments in the scientific study of Heat sinks: thermal management components made of materials with sufficient thermal conductivity qualities. Due to the increase in operating power, speed, and the general reduction in system size, the issues of heat removal and temperature management have an increasing importance in these studies. Changing the geometry of extended surfaces, the material from which they were made, the working fluid that ran over them, and/or the dimensions of the channel, are some of the ways in which studies have been conducted. This review addresses the main recent findings in forced convection heat transfer that happens at laminar flow inside small-scale diameter channels. Recent studies indicate a remarkable enhancement through the change of Re, D, and internal geometry of the channel. The configuration of flow passages has also adopted a different passive technique to enhance thermal fluid flow.
