Cooling architecture
Technology
Direct-to-chip liquid cooling
A liquid loop moves heat from processor-mounted cold plates to a CDU and then to facility heat rejection.
Scaling · Commonly selected for 50–150+ kW AI racks
Technology
Single-phase immersion cooling
Servers operate submerged in a dielectric liquid that remains in the liquid phase while carrying heat to a heat exchanger.
Scaling · Often deployed from 50–200+ kW per tank
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
