摘　　要：以北京市某数据中心为例,采用计算流体力学方法进行了模拟,使用四因素三水平正交试验方法进行分析,探究了不同地板高度、格栅孔隙率、导流板角度和回风口尺寸对热工性能的影响。结果表明,对热工性能影响最大的因素是导流板角度,其次是地板高度。建议最佳配置为地板高度0.4 m,格栅孔隙率35%,导流板角度90°,回风口尺寸0.7 m×0.8 m。经过本研究的优化,机柜最高温度减少了10.76%,实现了降本增效。A data center(DC)in Beijing,for example,was simulated using computational fluid dynamics,and analyzed u⁃sing a four-factor,three-level orthogonal test method to investigate the effects of different floor heights,grille porosity,deflec⁃tor plate angles,and return air outlet sizes on thermal performance.The results show that the most influential factor on the ther⁃mal performance of the DC is the deflector angle,followed by the floor height.The optimal configuration is suggested to be floor height of 0.4 m,grille porosity of 35%,deflector angle of 90°,and return air outlet size of 0.7 m×0.8 m.After the optimiza⁃tion,the maximum temperature of the cabinet is reduced by 10.76%,which achieves the reduction of cost and increase of effi⁃ciency.
