With the continuously increasing packaging density, the corresponding techniques for heat dissipation are vital to high performance components. During the system operation, the heat generated by components must be efficiently transferred outside of the electronic package. To meet the heat removal requirement of the electronic devices with a high power, several liquid cooling schemes have been suggested,...
Carbon nanotube (CNT) can be used in micro-channel cooler construction due to its excellent thermal conductivity. When fabricating CNTs directly onto the chip, the chip could be damaged because of the high temperature required for CNT growth (about 750°C). As a solution, a transfer technique is developed where the desired carbon nanotube pattern can be obtained by taking off a pre-fabricated CNT forest...
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...
