一种数据中心机柜，如图1所示，包括机柜本体、分油装置4、若干布液器7；所述的机柜本体包括若干安装架；所述的机柜本体由高至低依次安装有若干服务器外壳10；所述的服务器外壳10内安放有服务器；每一所述的服务器外壳 10上方设有一所述的布液器7；所述的分油装置4与所述的布液器7通过进油装置6连接；冷却液态油通过泵2泵入所述的分油装置4内，所述的分油装置4在所述泵2压力作用下分油流至所述的布液器7，所述的布液器7喷淋冷却液态油至服务器上冷却。一般的，为保证机柜整体结构强度，机柜本体由金属材料制成；特殊的，柔性材料也可引入制造机柜本体。
优选地，如图3、图4所示，所述的布液器7包括回油腔71、喷淋油腔72、布液进油口73、回油口74；所述的回油腔71位于所述的喷淋油腔72上方；所述的布液进油口73位于所述的喷淋油腔72内；所述的喷淋油腔72下底面设有喷淋孔76；所述的喷淋孔76正对所述的服务器；所述的回油腔71承接流经所述布液器7上方的服务器中的冷却液态油；所述的回油口74用于排出所述回油腔71中的冷却液态油。优选地，所述的布液器7还包括溢流孔75；所述的溢流孔75设于所述的喷淋油腔72下底面；所述的溢流孔75高于所述的喷淋油腔72下底面；所述的回油腔71与水平面呈一夹角。如图2所示，回油口74正对回油装置8的回油箱，从回油口74回流的冷却液态油经过回油箱流入主油箱1中。每层服务器对应的布液器7设置有若干个溢流孔75，溢流孔75高度高于淋油板5-20mm，保证喷淋油腔72内油位深度。当进油量大于淋油量时(如检修单层服务器时)，多余的油量通过溢流孔75进入服务器；溢流孔75位置设置于发热元件相对集中的区域，提高服务器的散热效率。
应当理解，布液器7作用为将从分油装置4中分油后的冷却液态油按照需冷却的实际部位在实际布液处理，一般的，将布液器7与服务器外壳10分开制造，布液器7如图3、图4中结构安装于服务器外壳10上，服务器外壳10为敞开结构。

优选地，为解决为不同高度服务器外壳10提供均匀压力与流量的冷却液压油，压力分油装置4包括分油压力调节阀；所述的分油压力调节阀调节对应所述的布液器的分油支路出口处的出油压力；应当理解，分油压力调节阀与进油调节阀作用都为确保冷却液态油进入布液器7中压力、流量一致，可单一使用或组合使用，达到恒压恒流作用。
