| 摘 要： | 以小型数据服务机房为研究对象，对机房使用列间空调后的气流组织进行了分析。利用CFD(流体动力学)软件对房间内的气体流动情况进行模拟，绘制温度、矢量风速计算云图，对比了冷通道封闭前后房间温度场、风场的变化，分析封闭前后室内换热情况。研究发现，冷通道封闭后离地0.5、1.5m处平均温度较封闭前平均温度下降2℃左右，机柜顶面下降1℃左右。封闭冷通道能够优化气流组织，有效避免气流短路，机房内局部热点消失，无效换热减少。

| Abstract: | With the small data service room as the research object, the airflow distribution of the room after using in-row air conditioning was analyzed. By using CFD (hydrodynamics) software, the airflow in the roomwas simulated, the temperature and vector wind speed calculation clouds were drawn. The temperature field and flow field before and after the cold channel closure were compared, and the indoor heat transfer was analyzed. Results show that after closing the cold channel the average temperature at 0.5 m and 1.5 m above the ground is about 2 ℃ lower than before, and the top of the cabinet is about 1 ℃ lower.Closing the channel can optimize the airflow distribution and avoid the short circuit of airflow effectively. Meanwhile, the local hot spots disappear, and invalid heat transfer is reduced. |
