Immersion Cooling for High-Density AI

Advanced immersion cooling fluids designed to help manage the thermal demands of high-density AI infrastructure

AI workloads are increasing compute density, rack-level power, and the thermal design power of next-generation chips. As more power is concentrated into AI and HPC racks, conventional cooling approaches face increasing pressure. This is driving interest in advanced immersion cooling strategies that can support higher thermal loads with reliability, efficiency, and operational confidence.

Immersion cooling fluids for next-generation AI infrastructure

For the most demanding high-density AI and HPC environments, immersion cooling provides a compelling path forward. In immersion cooling, electronic components are submerged in a dielectric fluid that helps remove heat while supporting electrical isolation. Within this category, two-phase immersion cooling offers the strongest performance case, using phase change to deliver very high thermal cooling capacity and efficient heat removal for next-generation rack architectures.

In two-phase immersion cooling, the fluid boils at the heat source, carries thermal energy as vapor, and then condenses back into liquid within the system. Because the fluid is central to the cooling mechanism, performance depends on boiling behavior, dielectric properties, stability, compatibility, safety, and long-term reliability. Selecting the right immersion cooling fluid requires a system-level view of performance, reliability, and operating conditions. Customers evaluating two-phase immersion cooling should consider how the fluid performs thermally, how it supports electrical insulation and compatibility with the materials used throughout the cooling environment and the electronics, the fluid stability over time and how it operates in a safe manner and operational maintenance.
