In this work, silicon microchannel coolers were made using the deep ion reactive etching (DIRE) technique. Stable and homogeneous carbon nanotube (CNT) suspension was also prepared. Meanwhile, a closed-loop cooling test system was developed to investigate the heat removal of the silicon microchannel cooler with different coolants. The experimental setup included a test module, a minipump for providing...
As power density in electronic system is approaching a level that conventional cooling methods canpsilat handle, reliability of microsystems is of large concern. In this paper, novel schemes for heat dissipation on electrical components have been reviewed with a strong focus on using carbon nanotubes (CNTs) as cooling fins as a basic approach. With an extraordinary high thermal conductivity, CNT is...
The 2D CFD simulations have been carried out for a series of CNT micro-fin cooling architectures based on two dimensional fin array models in this paper. The influence of micro-fin structures, fluid speeds, heating powers and effective thermal conductivity on cooling effects have been obtained in the case studies, and the 2D fin array simulation results have been compared with our previous 1D fin...
The 2D CFD simulations have been carried out for a series of CNT micro-fin cooling architectures in this paper. The influence of micro-fin structures, fluid speeds and heating powers on cooling effects have been obtained in the case studies, and the numerical results have been compared with our experiment data. The CFD simulations indicate that the fluid speed is the key factor of heat transfer, and...
