Oracle AI data centers adopt closed-loop non-evaporative cooling

Oracle announces it will implement closed-loop, non-evaporative, direct-to-chip cooling in its new AI data centers in several U.S. states.

• Main announcement: Oracle will deploy closed-loop, non-evaporative, direct-to-chip cooling in AI data centers in New Mexico, Michigan, Texas and Wisconsin; the systems are filled initially via tanker trucks and then operate as a sealed recirculation system, so daily cooling does not consume community potable water.
• Background and details: The article cites an Uptime Institute estimate that conventional evaporative cooling can use on the order of millions of liters per MW per year; Oracle states that replenishment of coolant is rare and only for abnormal conditions, and that routine water use at the sites is limited to typical office occupancy needs. Oracle also notes local investments including hiring local staff, partnerships with colleges, and funding for infrastructure.
