摘要
目的研究分析一种分解大型电子设备机架风冷气流条件的方法。方法以温差和Nu数作为描述传热效果的参数,使用相似对流的方法,使分解夹具中模块两侧的气流传热效果等效于大型机架中模块两侧的气流传热效果。结果气流在分解后,其在分解夹具中的冷却效果等效于分解前其在大型机架中的冷却效果。结论该分解方法能够有效地进行风冷气流条件分解,可以应用于实际工程。
Objective To research the airflow decomposition method for large electronic racks.Methods With temperature difference and Nu as parameters for describing heat transfer performance,and based on the similar convection method,heat transfer performance in the decomposed fixture was made equivalent to the performance in the large rack before decomposition.Results After the airflow was decomposed,its cooling performance in the decomposed fixture was equivalent to the performance in the large rack.Conclusion The cooling airflow can be effectively decomposed by the method which can be applied to practical engineering.
