Geometric optimization of carbon nanotubes (CNTs) microchannel with liquid flow

Recent advances in micro electromechanical devices, advanced very large-scale integration technologies and the associated micro miniaturization, have led to significant increases in the packing densities and heat fluxes generated within these devices. How to remove so high heat fluxes, it becomes more and more important. In this paper, three models of CNTs micro channel coolers are established, which are rectangular channel model, rectangular array model and diamond array model. The variations of the pressure drop and temperature rise of different models are compared. It is found that the rectangular array model has good heat dissipation performance.
