摘要

本文评估了服务器机架压降对IT设备冷却的影响。通过测量服务器内阻、机架门、CMA (Cable Management Arms)等的阻抗曲线，估算冷却气流减少的幅度。本研究以1台RU服务器和2台RU服务器以及一台9台RU服务器模拟器作为代表性IT设备。采用计算流体力学(CFD)模型研究了齿条结构对热场的影响。实验还研究了冷却空气流量对服务器内部部件温度的影响。

Experimental characterization of pressure drop in a server rack

This paper evaluates the impact of pressure drop in server racks on the cooling of the IT equipment. The measured impedance curves for servers internal resistance, rack doors, and Cable Management Arms (CMA) are used to estimate the reduction in the cooling airflow rate. In this study, 1 RU and 2 RU servers, and a 9 RU server simulator are used as representative IT equipment. A Computational Fluid Dynamics (CFD) model is used to investigate the influence of the rack structure on the thermal field. The effect of the cooling air flow rate on the temperature of the server's internal components is also studied experimentally.
