| 摘 要： | 文中介绍了一种刀片服务器的液冷散热系统，对系统各部分的流量及管径进行了设计，同时通过仿真分析和实验测试来验证其散热性能。结果表明，液冷方案相比风冷方案能够将刀片内中央处理器（Central Processing Unit, CPU）支持的功率从165 W 提升到300 W，采用铲齿冷板和水工质并将流量控制在1.5 L/min 以下能够提高液冷系统的散热性能。最后对比分析了液冷和风冷系统的成本，液冷系统成本回收时间约为2.5年，长期运行具有良好的经济性。

| Abstract: | A liquid cooling system of blade server is introduced in this article. The flow and the pipe diameter of various parts of the system are designed. And the performance of heat transfer is verified by simulation and experiments. The result shows that the liquid cooling solution can increase the power of the blade CPU (Central Processing Unit) from 165 W to 300 W compared with air cooling solution. And the performance of the liquid cooling system can be improved by using spade-tooth cooling plates and water refrigerant and controlling the flow below 1.5 L/min. The costs of liquid cooling and air cooling are compared. The payback time of liquid cooling system is about 2.5 years, so the liquid cooling system is more economical for long-term operation. |
