| 摘要: |
| 数据中心的能耗增长日益受到关注，其能耗的很大部分是用于机房冷却。采用节能冷却方法是节能减排的迫切要求，自然冷却技术是其中的有效方法之一。自然冷却技术的实施有三种主要方式：空气侧自然冷却、水侧自然冷却和热管自然冷却。空气侧自然冷却简便易行且节能效果好，但会影响室内空气质量和湿度。水侧自然冷却可以在原有的空调机组上改造实现，但由于增加了中间传热过程其节能效果有限。热管自然冷却避免了对室内环境的影响，且同时利用相变传热节能效果较好。本文总结了近年来这三种自然冷却技术的最新进展，为这一领域的研究提供参考。 |

| Abstract: |
| The increasing energy consumption of data centers attracts more and more attention, much of which is consumed by the cooling system. Utilizing efficient cooling methods is the urgent need for realizing emission control targets, and the free cooling is one of these methods. The free cooling technology has three categories: airside free cooling, waterside free cooling and heat pipe free cooling. Airside free cooling is easily utilized and has good energy-saving effect, while it may affect the indoor air quality and humidity. Waterside free cooling can be modified from traditional air conditioner however its energy-saving effect is limited for additional heat transfer process. Heat pipe free cooling has no disturbance on the indoor environment and its energy-saving effect is good for utilizing phase change heat transfer. The latest advances in free cooling technology is summed up, which has the referential value for research in this field. |
