Cooling technologies
Technology
Hybrid air and liquid cooling
A facility combines liquid capture at high-heat components with air cooling for the rest of the rack.
Scaling · Broadly applicable from 30–150+ kW racks
Technology
Evaporative cooling
Water evaporation lowers air or process-fluid temperature before heat is rejected from the data center.
Established · Facility-level system; density depends on downstream distribution
Technology
Dry cooling
Air-cooled heat exchangers reject heat without evaporating process water during normal operation.
Established · Facility-level system sized to total rejected load
