N2 - Abstract The optimum design of a mini liquid radiator for cooling the CPU is proposed. The total volume of the radiator is 12.57 cm3 only. Its thickness and diameter are 1 and 4 cm, respectively. Present study compares four different models to verify the difference with experimental data. It is found that the results of the standard κ-ε turbulence model and experiment are most consistent. In this study, the effects of three kinds of fin types are investigated. This principle of the cooling system is to impinge water jet directly on the center of the CPU heat source. A vortex near the jet core is created such that the source heat at the bottom of radiator can be transferred upward. Further, the cooling water flows radially through the passages among the plate fins and cools down the hot fins. Due to the high efficiency, although the flow rate is very less, the heat resistance of the proposed radiator is very low. The dimension and heat resistance of the present radiator are significantly lower than those in the literature. Moreover, the heat transfer correlation equation is proposed. Based on this equation, one can easily and successfully design any cooling radiator.
