Sugon Launches World's First Mass-Produced MW-Class Immersion Cooling Cabinet at 900kW

Sugon Ships World's First MW-Class Liquid Cooling Cabinet: 900kW Single Rack, Two Years Ahead of Nvidia's 2028 Target

Chinese supercomputing company Sugon (曙光数创) has launched the world's first mass-produced MW-class phase-change immersion cooling cabinet, achieving 900kW per rack — a milestone Nvidia's Feynman architecture was targeting for 2028.

Technical Specs

Deployment

The system is already deployed at the National Supercomputing Internet core nodes (国家超算互联网核心节点), demonstrating real-world operational capability.

Why This Matters

1. AI infrastructure bottleneck — The #1 constraint on AI training clusters is no longer GPUs, it's power and cooling
2. Two years ahead — China reaching MW-class cooling before Nvidia's roadmap shows rapid advancement
3. Practical deployment — Not a prototype but already in production at national supercomputing facilities
4. Energy efficiency — Immersion cooling dramatically reduces PUE (Power Usage Effectiveness), critical as data center power demand soars
