Immersion cooling is a technique where servers and IT equipment are submerged in a thermally conductive, non-electrically conductive liquid to manage heat. This method removes heat more efficiently than traditional air or direct-to-chip cooling and supports dense, high-performance workloads.
How Immersion Cooling Works
In immersion cooling, hardware components like CPUs, GPUs, and memory modules are placed in a bath of dielectric fluid. This fluid absorbs heat directly from the surfaces of the components. The heated fluid then flows to a heat exchanger, where the heat is removed and the cooled fluid is circulated back.
There are two common types:
- Single-phase immersion: Fluid absorbs heat and is cooled without boiling
- Two-phase immersion: Fluid boils at low temperature and condenses to transfer heat more efficiently
Both offer low thermal resistance and eliminate the need for fans or air circulation.
Why Immersion Cooling Matters
As computing becomes denser and power-hungry, immersion cooling provides:
- High cooling efficiency with lower power consumption
- Reduced noise and space requirements
- Better thermal performance for AI, HPC, and blockchain
- Lower operational costs over time
It also enables sustainable data center operations by reducing reliance on air conditioning and chilled water systems.
Growth in India
Indian enterprises exploring AI, analytics, and edge computing are evaluating immersion cooling to support performance and sustainability. With rising energy costs and regulatory pressure, the shift to advanced cooling methods is expected to grow.
Data center operators in cities like Mumbai, Bengaluru, and Hyderabad are running pilots or planning deployments.
