What is Liquid Cooling in Data Centers?
Liquid cooling uses water or specialized fluids to remove heat directly from IT equipment. Since liquids have a much higher heat-transfer capacity than air, they are ideal for high-density racks (30 kW to 100 kW+ per rack).
Types of Liquid Cooling in Data Centers
1. Direct-to-Chip Cooling
In Direct-to-Chip cooling, cold plates are mounted directly on heat-generating components like CPUs, GPUs, and memory modules. Coolant flows through these plates and removes heat at the source.
Key benefits:
Highly efficient heat removal
Ideal for AI, HPC, and GPU-based workloads
Reduces dependency on traditional air cooling
Supports very high rack densities
2. Immersion Cooling
In Immersion Cooling, entire servers are submerged in a dielectric (non-conductive) liquid. Heat generated by components is transferred directly to the liquid.
Types of immersion cooling:
Single-phase immersion – fluid remains in liquid state
Two-phase immersion – fluid boils and condenses to remove heat
Key benefits:
Extremely high cooling efficiency
Eliminates server fans
Lower energy and water usage
Compact data center design

3. Rear Door Heat Exchanger (RDHx)

A Rear Door Heat Exchanger is a liquid-cooled door installed at the back of a server rack. Hot air from servers passes through the heat exchanger and is cooled before entering the room.

Key benefits:

Easy retrofit for existing data centers

Supports higher rack densities without major IT changes

Works alongside traditional air cooling

Lower CAPEX compared to full liquid solutions

Why Liquid Cooling Matters

Enables AI-ready and future-ready data centers

Improves PUE and energy efficiency

Supports sustainability and carbon-reduction goals

Reduces cooling footprint and operational costs
