Multi-Layer Micro Channels System: Interpretation and Developments

Abstract:

During the last three decades the concept of the traditional cooling systems was modified to include single, double, and multi-layer micro channels. The new studies, applications, fabrication, and research focus on four main areas: the geometrical shape of the micro channels, the number of stacked layers, the type of the coolants, and the heat performance optimization. The previous studies have shown a significant reduction in the power consumption as the optimization is accomplished. In this paper, a semi-review for the previous works is provided, an attempt to interpret the nature of the work done, and show another trial for optimization. In this study, water was used as coolant, stacked multi-channel was adopted, and thermal resistance network was calculated. The heat sink under consideration is a rectangle of width W and length L. The thickness Hsub of the base of the micro-channel is 100 [μ m] while the depth Hc of the micro-channel is 500[μ m], both kept constant for all future optimization cases.
