Immersion Cooling: What is it?
Immersing your server in a non-conductive liquid bath, allowing heat energy from the computer components to transfer into the liquid and be cooled through either a two-phase or single-phase approach.
Since traditional cooling technologies have high expenses associated with energy consumption, water use, square footage, carbon footprint, and other factors, immersion cooling is expected to become the standard in present and future data centers. Immersion-cooled data centers are more dependable overall, faster, more expandable, and energy-efficient. They also save more money for organizations.
Why Are Immersion Cooling Solutions Becoming More Popular in Data Centers?
Because the network may be installed anywhere, even in the warmest states, the climate is no longer a barrier. Immersion cooling may even be feasible in regions with harsh weather, such as places with high humidity, dust, or ambient temperatures.
Why Should Date Centers Opt-In for Liquid Cooling Their Servers?
Through the removal of active cooling elements like fans and heat sinks, immersion cooling enables a substantially higher processor density. The smaller "data center" may function with the same efficiency as a larger data center and is easily adaptable to urban settings with limited space.
The amount of heat produced by chips and computers rises with their respective tasks. This prompts industry leaders in data centers to investigate alternate approaches to thermal management that may prove to be more efficient than conventional air cooling.
Different Kinds of Immersion Cooling Fluids
The primary kinds of immersion cooling fluids found in data centers are as follows:
1. Mineral Oil: Used in single-phase systems, it is cheap and non-conductive.
2. Silicone Oil: utilized in single- and two-phase systems, it is stable, non-conductive, and has a higher thermal conductivity.
3. Fluorocarbon-Based Fluids: utilized in two-phase systems, these non-flammable and non-conductive fluids feature great heat absorption properties.
4. Synthetic lubricants: Used in single- and two-phase systems, these performance-engineered lubricants include POE (polyester oil) and PAO (polyalphaolefin).
5. Fibre-Based Hydrocarbon Fluids: Extremely pure, utilized in customized one-phase mixes.
6. Engineered Dielectric Fluids: Used in single- and two-phase systems, these fluids are high-performance in design.
7. Water-Glycol Mixtures: Effective, non-conductive, utilized in specific configurations.
