To maintain a stable thermal environment in the data center, the air conditioning system operates at high energy consumption levels annually. The airflow organization within the data center significantly impacts the cooling effectiveness of the air conditioning system. To achieve uniform airflow distribution, this study explores the effects of vertical and horizontal baffles placed between the air supply outlet and rack, both individually and in combination. This study explores the applicability of baffles in fan-wall data centers, analyzing and obtaining the optimal baffle angle, spacing, distance, and their corresponding thermal environment. This research aims to provide an optimized solution for enhancing thermal conditions within server rooms. The results indicate that: (1) Both vertical and horizontal baffles can improve the cold air trajectory from the air supply outlet to the rack, effectively improving the thermal environment of the rack. (2) Implementing a single vertical baffle at a distance of 0 cm and an angle of 75° effectively eliminates heat accumulation and achieves uniform temperature distribution. (3) When vertical or horizontal baffles are arranged individually, distance has a significant impact on airflow organization, however, when both vertical and horizontal baffles are combined, the influence of distance is minimal.

通过在冷通道中设置挡板改善风扇墙数据中心热管理的实验研究


为了在数据中心保持稳定的热环境，空调系统每年都以高能耗水平运行。数据中心内的气流组织会显著影响空调系统的冷却效果。为了实现均匀的气流分布，本研究探讨了放置在供气口和机架之间的垂直和水平挡板的影响，无论是单独还是组合。本文探讨了挡板在风扇墙数据中心中的适用性，分析并获得了最优挡板角度、间距、距离及其对应的热环境。本研究旨在提供优化的解决方案，以改善服务器机房内的热条件。结果表明：（1）垂直和水平挡板均能改善从送风口到机架的冷风轨迹，有效改善机架的热环境。（2） 在距离 0 cm、角度为 75° 处实施单个垂直挡板，有效消除热量积聚，实现均匀的温度分布。（3） 当垂直或水平挡板单独布置时，距离对气流组织有很大影响，但是，当垂直和水平挡板组合时，距离的影响很小。
