Data Center heat rejection: A deep investigation of the most common cooling strategies

Industry power trends are leading IT decision makers and data center operations groups to consider alternatives to traditional air cooling. Today, performance competition among CPU vendors is pushing CPU power towards 500 W per socket. AI/ML workloads have pushed GPU power to 700 W with 1000 W likely just around the corner. At the same time, the global energy crisis is pushing all sectors to be more sustainable. With servers and data centers, this sustainability push means operators are targeting green energy sources, overall reductions in facility energy use, peak power reduction, and elimination of water consumed. These industry challenges require new approaches to keeping chips cool and rejecting the heat to ambient most efficiently.

During this bespoke innovation day, five unique approaches to rejecting heat from IT equipment are evaluated: 1) air cooling using larger server chassis form factors, 2) direct liquid cooling (DLC) using water or Propylene Glycol (PG) solutions, 3) DLC using 2-phase dielectric fluids, 4) single phase immersion, and 5) 2-phase immersion. A panel of experts will discuss the findings and Munters will present solutions that efficiently reject data center heat to ambient.
