查询词典 airflow

The meteorological conditions of Culex tritaeniorhynchus emerging in spring were not the same as that of the Anopheles sinensis which overwintered in local area but in conformity with the landing pattern of seasonal northward migratory insects,which were transported by the SW-air-current and the sinking airflow due to the passing through of the front with the rain-fall,or the shear of wind direction and the positive variations of atmospheric pressure.

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.
