CFD Analysis for 2D-Micro fin Array with Carbon Nanotube Structured Surfaces for Cooling Applications

The next generation microchips with high power densities would require novel methods of cooling. Micro channels provide an effective way of cooling microchips. CNTs are made from cylindrical carbon molecules which are very special in thermal, electrical and mechanical properties. A thermal conductivity up to 6600 W/m·K has been reported. The 1D and 2D CFD simulations have been carried out for a series of CNT micro-fin cooling architectures based on one and two dimensional fin array models in this paper.The analysis indicates that fluid speed is the key factor of heat transfer and 2D carbon nano tube fin array shows greater thermal performance than that of 1D carbon nano tube fin array. The pressure drop between inlet and outlet of the cooling device is an important cause to limit the fluid speed.
