Liquid Cooling
Moving heat away from servers using liquid — either cold plates attached to chips or full immersion in a dielectric fluid — instead of moving air.
Why does it matter?
Modern accelerator racks produce more heat per square metre than air can practically remove. Liquid cooling lets operators fit more compute into existing buildings and cut the energy spent on cooling itself.
How does it work?
Coolant circulates through cold plates or a filled tank, absorbs heat directly at the source, and transfers it to a facility water loop or dry cooler outside.
Where is it today?
Direct-to-chip cooling is becoming standard in new high-density builds. Retrofitting older air-cooled halls is the harder and more common problem.
