Immersion Liquid Cooling, the Complete Anatomy of a Fully Submerged Data Center
One Ton of Tank on 800-to-1,500-kg Floor Loading, a Bund Around Every Box and Near-Silent Racks at 50 to 200+ kW: The Discipline Behind the 1.03 PUE
Immersion cooling submerges the whole server in insulating coolant and takes over where air cooling hits the ceiling, with TrendForce projecting penetration near 60 percent by 2027. The route splits into single-phase, where coolant stays liquid and a northern intelligent computing center saves more than 30 percent energy over air, and two-phase, where the fluid boils at about 50 degrees and the vapor returns by gravity within ±1 degree. Typical racks run 30 to 100 kilowatts single-phase and 50 to 200-plus two-phase with PUE at 1.03 to 1.10, near-silent with no fans. A filled 42U tank passes one ton, floor loading rises to 800 to 1,500 kilograms per square meter, a bund with sensors surrounds every tank, and the CDU integrates pumps, plate heat exchanger and redundant pump sets behind zero-leakage piping. EXTRCOOL provides one-stop liquid cooling solutions.
