Cooling technology • Technology
Servers operate submerged in a dielectric liquid that remains in the liquid phase while carrying heat to a heat exchanger.
Architecture
Single-phase immersion removes server fans and places compatible hardware in an open or enclosed tank of dielectric coolant. Pumps or natural convection move warmed fluid through a heat exchanger without boiling it.
