The Unmatched Performance of 2-Phase Immersion Cooling

The new standard in advanced data center cooling explained

Cooling the Next Generation of Computing

High performance computing (HPC) and data-intensive technology applications like machine learning (ML), artificial intelligence (AI) and high-definition video processing use servers and chips that produce too much heat for air cooling to be practical or efficient.

The Passive 2-Phase Immersion Cooling Cycle

2-Phase Immersion Cooling Explained

  • Electronics are completely immersed in dielectric (non-conductive) fluid with no need for bulky heat sinks or fans
  • Chip temperatures rise until the fluid boils
  • Phase 1 of heat transfer occurs as the hot vapor rises
  • Phase 2 occurs as the vapor condenses on a specialized coil
  • Condensed fluid falls back into the tank as droplets, beginning the cycle again
  • The phase change of boiling leads to automatic convection and higher heat rejection capacity
  • The cooling process is entirely passive, with no pumps or moving parts required to reject IT heat
