Abstract

Carbon nanotube (CNT) has been proven to be an effective material for the thermal management of MEMS-based devices due to its superior thermal conductivity. At the same time, micro-channel heat-sinks are widely used in electronic products as a high performance heat transfer device because of its simple construction, easy fabrication process and effective heat removal capability. A numerical study has been carried out to investigate the thermal-fluid characteristics of the aligned and staggered MWCNT (multi walled CNT) based micro pin fins having 650 µm long with hydraulic diameter of ~130 µm. Average heat transfer coefficients have been obtained for effective heat fluxes ranging from 50 to 130 W and Reynolds numbers from 14 to 160. The influence of various fluids, fluid velocity; fluid conductivity, fin material, fin conductivity, fin geometry and fin orientations on cooling effects have also been investigated and compared in this study.
