Cray has unveiled a petascale-era cooling technology it says is more than 10 times as efficient as same-size water coils. They call it ECOphlex technology.
The cabinet infrastructure can use either Cray’s high-efficiency vertical air cooling or our new phase change cooling technology that converts an inert refrigerant, R134a, from a liquid to a gas. The other flexibility is that the liquid-cooled systems can use various chilled or unchilled datacenter water temperatures to pull heat from the R134a subsystem and to adapt to changing datacenter conditions.
The cooling technology will be used in the new XT5 family of supercomputers.
