摘　　要：安全壳循环冷却机组由于进风断面跨度大,断面风速分布不均匀,从而影响设备性能。为解决这一问题,对安装有6种结构型式的孔板均流器的空调内部进行流场分析,并进行试验验证。结果表明,设置梯度孔隙率的孔板均流器能够显著改善断面风速的均匀度。Because of the large span of containment circulating cooling system（CCCS）air intake section,the air velocity is not uniform,which influences the equipment performance.In order to solve the problem,the flow field analysis of six structural types of orifice equalizer are conducted and tested.It is proved that orifice equalizer with gradient porosity can significantly increase the section air velocity uniformity.
