数据机房气流仿真模拟与优化研究

Research on Simulation and Optimization of Air Flow in Data Room

ε本研究针对数据机房建立了k-两方程湍流模型和机房几何模型,具体介绍了机房内服务器、风口等部件的典型建模方式,利用该模型对机房的室内热环境进行气流仿真模拟。对比得出各区域的温度模拟结果与机房实测数据平均误差低于5%,最大误差低于15%,验证了该模型的准确性。同时根据此模拟结果分析得出机房局部热点形成的原因主要是热短路、热堆积以及回风气流受阻。针对以上问题提出机房热环境优化思路。

This study established k-εthe two equation turbulence model and the geometric model of the computer room,specifically introduce the typical modeling methods of components such as servers and air vents in the computer room,and use this model to simulate the airflow in the indoor thermal environment of the computer room.The average error between the temperature simulation results of each region and the measured data in the computer room is less than 6%,which verifies the accuracy of the model.At the same time,based on the simulation results,it is analyzed that the main reasons for the formation of local hotspots in the computer room are thermal short circuits,thermal accumulation,and blocked return air flow.Propose ideas for optimizing the thermal environment of the computer room in response to the above issues.
