Japanese telecom bets on liquid cooling to take the heat out of AIs energy crisis - JStories

▤ Summary

KDDI has commercialized liquid immersion cooling for AI data centers and is deploying it at industrial scale in Osaka. The company says the system cuts server cooling energy use by 94 percent and lowers PUE to 1.05 compared with conventional air-cooled facilities. KDDI built the solution with Mitsubishi Heavy Industries and NEC Networks & System Integration, then moved from demonstration to commercial rollout. The article frames the launch as a response to rising AI power demand and growing pressure on data center infrastructure. It also notes that the approach reduces cooling load, not the underlying electricity demand from AI chips.
