The method of CFD numerical simulation is employed to replace experimental investigation. Hence, STAR-CD of the commercial software is used to simulate the outer flow field and heat transfer performance of integrated heat sink with heat pipes cooled by airflow. It is found that simulated results agree with experimental results well, which indicates that simulation method is reasonable and reliable. Further, simulated computations for different fin thickness, fin pitches and air velocities are performed to analyze their effects on heat transfer performance of heat sink. Finally, a new optimized structure of integrated heat sink with heat pipes is provided to meet future demands for cooling CPU and its heat transfer is also evaluated. For multi-heat source and higher dissipation power of electronic devices, the integrated heat sink with heat pipes attatched fins stagged in different positions of channels is presented and its flow and temperature fields are also simulated to enhance heat transfer. As a conclusion, all mentioned above are useful for the design of heat sink with excellent efficiency of heat dissipation and further research.

The results indicate that the cooling rate of melt droplet that can not break further depends not only on its diameter, but also on its position in atomizing chamber. As a result, the same sized particles in different positions show different cooling rates and two different kinds of microstructures. The cooling rates of melt droplets range from 104 to 108 K/s, and the critical cooling rate for glass formation of Al-Ni-Y is about 105 K/s. Moreover, the corresponding maximum diameter of amorphous particles is 25 μm, which accords well to the theoretical analysis results. The new approach, reflecting the complexity of close-coupled gas atomization objectively, is available and effective to evaluate the cooling behaviors of close-coupled gas atomization.
