Air-Based Cooling

Air-based cooling remains the most prevalent method, particularly in older facilities and for lower-density racks. It relies on moving ambient or chilled air through server racks to absorb heat. Key technologies include:

• Computer Room Air Conditioners (CRACs) and Computer Room Air Handlers (CRAHs): CRACs cool and dehumidify air using refrigerants, while CRAHs use chilled water from an external chiller. They circulate cool air into the data center.
• Hot/Cold Aisle Containment: This involves physically separating hot and cold air streams to prevent mixing, significantly improving the efficiency of air-based cooling by ensuring that only cool air is supplied to IT equipment inlets and hot air is efficiently returned to cooling units.
• Economizers (Free Cooling): These systems leverage outside air or chilled water from external sources when ambient temperatures are low enough, reducing the reliance on mechanical refrigeration and saving significant energy.

While generally less efficient for high-density environments, continuous innovations in air-side economizers, intelligent airflow management, and containment strategies are extending the viability of air-based cooling for many applications.

Liquid-Based Cooling

Liquid cooling is rapidly gaining traction due to its superior heat dissipation capabilities, energy efficiency, and suitability for high-density computing environments. It involves using a liquid coolant (water, dielectric fluid) directly in contact with or very close to heat-generating components.

• Direct-to-Chip (Cold Plate) Cooling: This method uses cold plates directly mounted onto hot components (CPUs, GPUs), through which a liquid coolant circulates to remove heat. It offers highly efficient localized cooling and can be integrated with existing air-cooled environments.
• Immersion Cooling: This involves submerging IT hardware directly into a non-conductive dielectric fluid.
  • Single-Phase Immersion Cooling: Servers are immersed in a fluid that remains in its liquid phase, transferring heat away through a heat exchanger.
