Abstract—In this paper, the 2D and 3D CFD simulations have been carried out in liquid-cooled carbon nano tube based (CNT) micro-fin cooling architectures. The effect of heat transfer due to fluid velocity, pressure difference in the micro-fin assembly and thermal expansion due to temperature rise in the cooling assembly have been analyzed in this paper. The analysis indicates that fluid speed is the key factor of heat transfer and 2D carbon nanotube fin array shows greater thermal performance than that of 1D carbon nanotube fin array. The pressure drop between inlet and outlet of the cooling device is an important cause to limit the fluid speed.
Index Terms—CNT; micro-fin; CFD; cooling assembly; thermal expansion.
