摘要
为了解决由于服务器设备散热效率低,布局不合理等原因引发服务器温度过高,造成硬盘、显卡等多处重要部件加速老化,故障频发的问题。文中采用商用的CFD软件6Sigma DC,对机房温度场进行建模仿真。然后根据仿真结果对机房服务器布局进行优化,并加强屏柜中服务器设备的通风及防尘功能,将服务器前屏柜门由原来的玻璃封闭式改造成全透气蜂巢通风式六边形网孔门。同时,将后屏柜门由原来的下风口式或圆网孔式改为全透气蜂巢通风式六边形网孔门,加强服务器的通风散热;且在服务器进风口处增设防尘罩,将灰尘拦截在防尘罩处,从而降低机房服务器的温度,使服务器能够稳定高效运行。仿真结果显示,优化后机房温度分布均匀,未出现局部温度过高的情况。
In order to solve the server equipment cooling efficiency is low,unreasonable layout of the cause of the server temperature is too high,resulting in a hard disk,graphics and so many important parts of accelerated aging,frequent breakdown problems,the commercial CFD software 6 Sigma DC is used in this paper to simulate the temperature field of the room.Then the layout of the server is optimized according to the simulation results,and the ventilation and dustproof function of the server equipment in the cabinet is strengthened.The server before the screen from the original glass door closed door screen is reformed into air ventilation type hexagonal honeycomb Kong Menping door,and after the screen door there is an original type screen door or circular screen mesh type transparent to the full type hexagonal honeycomb ventilation ventilation door,ventilation and dust and the addition of the server; cover on the server at the inlet,the dust interception in the dust-proof cover,thereby reducing the server room temperature,the server can run stably and effectively.The simulation results show that the temperature distribution of the machine room is uniform after optimization,and there is no case of high local temperature.
