摘要
IBM has delivered a supercomputer cooled by hot water to the Swiss Federal Institute of Technology Zurich (ETH Zurich), which IBM says marks “a new era in energy-aware computing.” The Aquasar cooling system uses water at temperatures of up to 140 degrees, and as a result consumes up to 40 percent less energy than a comparable air-cooled machine. The system also uses waste heat to provide warmth to university buildings, reducing Aquasar’s carbon footprint even further.

Aquasa超级电脑部署了一种芯片级的液体冷却系统，水的温度最高可以达到60摄氏度，相比空气调节系统，能减少最多40%的能量消耗。这项技术的奥妙在于水温能让芯片的运行温度维持在极限的85摄氏度以下，传统液体冷却系统使用较低温度的水，但是冷却液更高的输入温度却能产生更大的吸热效应。IBM声称该系统还能用废热为建筑物保温，进一步减少碳足迹。�
