Influence analysis on thermal discharge of cooling system of a large data center using low-temperature reservoir water as cooling water source

中文摘要英文摘要

水库水源的低温水冷却系统是解决数据中心能耗问题的一种有效手段,但产生的温排水对环境的影响亦不容忽视.以武当云谷大数据中心为例,基于MIKE21 FM软件建立了丹江口水库坝下至黄家港水文站的平面二维数值模型,研究了数据中心温排水退水口设在不同位置对温排水扩散规律的影响.结果表明:随着温排水退水口位置处水深和流速的增大,温排水的最大温升和相应的温度混合区范围也逐渐减小,当水深超过2m时,局部最大温升已低于1℃.研究成果可为采用水库低温水作为冷却水源的类似数据中心温排水退水口选址及温排水影响分析提供借鉴.

Low-temperature water cooling is an effective means to solve the energy consumption problem of data centers,but its environmental influence of the generated thermal drainage cannot be ignored.Take Wudang cloud valley big data center as an example,based on the MIKE21 FM software,a two-dimensional numerical simulation model from Danjiangkou Reservoir Dam to Huangjiagang Hydrological Station was established,and the influence of different locations of the cooling water outlet of the data center cooling system on the diffusion law of thermal discharge was studied.The results showed that with the increasing of water depth and flow velocity at outlet,the maximum temperature rise of the thermal discharge and the corresponding temperature mixing zone gradually decrease.When the water depth exceeds 2 m,the local maximum temperature rise is less than 1℃.The research results can provide reference for the site selection of the data center cooling water outlet and the analysis on influence of thermal discharge using low temperature reservoir water as the cooling water source.
