SUMMARY:Advancing AI: Trade-Offs Between Single-Phase and Two-Phase Liquid
  Cooling
DESCRIPTION:Reza Najjari and Neil Mulji (CoolIT Systems)\n\nWith the growt
 h of AI, liquid cooling of IT equipment is no longer optional. Power consu
 mption and heat dissipation have dramatically increased. Liquid cooling is
  now required to manage heat loads of AI semiconductors with much higher h
 eat fluxes and AI servers with much greater rack densities.\n\nThere are t
 wo core approaches to liquid cooling: single-phase, using water or a water
 -glycol mixture as a coolant, and two-phase, using refrigerants. In single
 -phase cooling, the coolant remains in the liquid state, whereas in two-ph
 ase cooling, the refrigerant changes between liquid and gas phases.\n\nIn 
 this forum, we will provide a technical assessment of single-phase and two
 -phase direct-to-chip liquid cooling (DLC) technologies, focusing on syste
 m design and operational differences. These differences help explain why s
 ingle-phase DLC is a mature technology now seeing mainstream adoption. In 
 contrast, two-phase DLC is earlier in the technology adoption cycle and st
 ill faces technical and operational hurdles.\n\nTag: Artificial Intelligen
