What Is Immersion Cooling?

Immersion cooling is a cutting-edge thermal management method where entire servers or IT components are submerged in a thermally conductive, dielectric liquid. This liquid directly absorbs the heat from the hardware, eliminating the need for air cooling, heat sinks, or traditional server fans.

There are two primary types of immersion cooling:

• Single-phase: The liquid stays in liquid form as it absorbs heat, which is then removed via a heat exchanger.
• Two-phase: The liquid evaporates when it absorbs heat, forming a gas. The gas then condenses back into liquid in a closed loop.

Both methods outperform air and even direct-to-chip cooling in terms of thermal efficiency and rack density potential.

Advantages

• Extreme Density Support: Enables ultra-high-density deployments well beyond what air or even direct-to-chip systems can handle.
• Superior Thermal Efficiency: Liquid removes heat far more effectively than air. With direct contact cooling, server components remain consistently cool under full load.
• Silent Operation: Fans are no longer needed in the server, reducing power usage and noise in the data hall.
• Reduced Mechanical Complexity: Fewer moving parts mean less wear and lower failure rates.
• Improved Energy Use: Immersion systems often enable Power Usage Effectiveness (PUE) < 1.05, especially in optimized environments.
• Potential for Heat Reuse: Captured heat can be reused for district heating, industrial processes, or converted into chilled water, aiding sustainability goals.
• Space Efficiency: Immersion tanks can consolidate massive compute power into a much smaller physical footprint.

Considerations and Trade-Offs

Despite its technical appeal, immersion cooling requires a rethinking of how data centers are designed, operated, and serviced:

• Server Compatibility: Not all IT equipment is immersion-ready. Servers often need to be purpose-built or modified to operate submerged in dielectric fluid.
• Physical Access and Maintenance: Servicing submerged components can be more complex and time-consuming compared to traditional racks.
• Operational Culture Shift: Technicians need new workflows, tools, and safety training to handle immersion systems effectively.Fluid Management: Dielectric fluids must be monitored and maintained over time. Disposal and environmental considerations also apply.
• Limited Industry Standardization: While gaining traction, immersion cooling still lacks some of the maturity and interoperability seen in air or D2C systems.
• Upfront Investment: Initial CapEx for immersion infrastructure is high, though often offset by long-term energy and space savings.

Ideal Use Cases

• AI & Machine Learning Clusters: Workloads that generate intense, sustained heat benefit from immersion’s consistent cooling performance.
• HPC Environments: Where performance and density outweigh other concerns, immersion is often the best fit.
• Edge Computing & Harsh Environments: Immersion systems offer sealed, ruggedized designs ideal for dusty, remote, or temperature-variable locations.
• New Data Center Designs: Immersion cooling shines in greenfield builds, where infrastructure can be optimized from day one.

What is an adiabatic cooling system?

An adiabatic cooling system is an energy-efficient cooling solution that leverages the natural process of evaporation to reduce air temperature without the need for traditional refrigeration. This technology works by introducing water into hot air streams, where the evaporation process occurs naturally, creating a cooling effect that reduces the overall temperature of the medium being cooled.

Unlike conventional cooling systems that rely on mechanical refrigeration, adiabatic cooling uses the principles of thermodynamics to achieve temperature control through minimal energy consumption. The process involves no heat transfer to or from the surrounding environment, making it an efficient solution for various industrial and commercial applications.

How do adiabatic cooling systems work?

Adiabatic cooling systems operate on the fundamental principle that when water evaporates, it absorbs heat from the surrounding air, effectively reducing the temperature. The process begins when hot air enters the system, where it encounters water through various delivery methods such as spray nozzles or wetted media.

As the air passes through the system, evaporation occurs when water molecules absorb energy from the hot air and transform into vapor. This transformation removes heat from the air stream, resulting in cooler, more humid air exiting the system. The fan units within the system ensure proper air circulation and pressure management throughout the cooling process.

The effectiveness of an adiabatic system depends on several factors, including ambient temperature, humidity levels, and the design of the equipment. In environments with lower humidity, the evaporation process is more efficient, allowing for greater temperature reductions with minimal water consumption.
