数据中心机架式服务器选型对其热环境的影响及优化分析

Effect and optimization of rack servers selection in data center on the thermal environment

数据中心热环境是空调系统制冷效果和能量利用的综合体现,其优良受到诸多因素的影响。为研究机架式服务器的选型对数据中心热环境的影响,对三种不同功率的1U服务器的数据中心进行仿真模拟,并分析优化其热环境。结果表明,采用封闭冷通道、增加空U挡板和提高送风温度均能改善机房的热环境,提高冷量利用率。

The thermal environment of data center is a comprehensive reflection of air flow distribution and energy utilization, whose performance is influenced by different factors. Simulation on three 1U rack servers with different powers was carried on to an- alyse the effect of rack servers design on the thermal environment in data center. Measurements results show that these methods such as adding cold aisle enclosure, adding baffles and increasing supply - air temperature can improve the air flow and cooling effect.
