Abstract

In this study, a complete cooling model composed of a double-entry centrifugal fan and a longitudinal-plate heat sink is investigated. The cooling model is popular in the notebook and some electronic systems. Due to the complexity of the coupled system, the performance of a fan and a heat sink are investigated separately in the literature. Thus the overall cooling mechanism and the best cooling efficiency of the system have not been revealed. The overall flow field is investigated by implementing the k − ε turbulent model in this paper. The best coefficients are determined by comparing the numerical results and the experimental ones. Moreover, the influence of parameters of fin on the overall flow field and the cooling system is investigated.
