小型数据中心的冷气出口设计

Air-conditioning Outlet Design for Small Data Centers

冷却系统是数据中心机箱正常运行的基础。而本文是通过设计合理的出风口位置,机柜的摆放以及出风方式,能有效的提高冷风利用效率,从而达到节约资源的目的。而本文首先对进风方式选择进行了分析与设计,之后我们是通过设计冷热通道解决了冷风与热风接触的问题。而后我们通过热传导方程,热传导率以及有限差分法并运用MATLAB得到温度以及热量与位置的关系。我们也可以通过天花板各点处的热量以及单位时间内空调进气口气体进来的体积建立起以天花板每个位置进气口需要进入的体积为目标的非线性规划模型。同时为了提高冷风利用效率,我们定义了与热空气容器的安全距离。最后我们用了模拟退火算法,即通过随机搜索一个初值和移动位置去寻求最优解。

The cooling system is the basis for the normal operation of the data center chassis.In this paper,through the design of reasonable air outlet location,cabinet placement and air outlet method,the efficiency of cold wind utilization can be effectively improved,so as to achieve the purpose of saving resources.This article firstly a nalyzes a nd selects the air intake method,a nd then we solve t he problem of contact between cold air and hot air by designing cold and hot channels.Then we use the heat conduction equation,heat conductivity and finite difference method and use MATLAB to obtain the relationship between temperature and heat and position.Then we can also establish a non-linear programming model aiming at the volume that the air inlet of each position of the ceiling needs to enter through the heat at each point of the ceiling and the volume of the air intake air in the air per unit time.At the same time,in order to improve the efficiency of cold w ind utilization,we have defined a safe distance from the hot air container.Finally,we used a simulated annealing algorithm,which seeks the optimal solution by randomly searching for an initial value and moving position.
