Immerse your servers in liquid!
Although it may sound unusual at first, immersion cooling is a completely safe, reliable, and increasingly popular technology in the world of data centers. Unlike traditional air-based cooling methods, this solution provides efficient heat removal directly in the server environment, which is becoming increasingly important as IT equipment demands more and more power.
The technology is simple in principle, yet extremely effective. IT equipment is immersed in a special, electrically non-conductive liquid contained in a closed, insulated tank. This liquid not only safely surrounds the components, but also continuously absorbs the heat they generate, thus preventing overheating. The heated liquid is cooled back down via heat exchangers connected to an external recooler. This enables the system to dissipate large amounts of heat in a stable and controlled manner. Although liquid cooling forms the basis of the system, supplementary air cooling continues to play an important role, as it removes around 5 percent of the total heat load.
The advantages of immersion cooling are convincing in many respects. Energy consumption can be reduced by up to 50 percent, resulting in significant cost savings in the long term. The space required for the same performance is only one-third of that required by conventional solutions, freeing up valuable space in data centers. The technology also enables much higher rack density, providing up to 250 kW of power in a single rack, which is particularly important in environments that require high computing power, such as artificial intelligence or large data processing systems.
In addition, immersion cooling enables exceptionally low PUE values, typically between 1.02 and 1.04. This not only demonstrates the efficiency of the system, but also represents a significant step towards sustainability, as reducing energy consumption significantly reduces the ecological footprint of data centers. Liquid cooling also generates minimal noise, making it much quieter than traditional fan-based systems.
Overall, immersion cooling not only represents the technology of the future, but also offers tangible benefits today: it ensures safer, more economical, and more environmentally friendly operation for data centers, while creating opportunities for even greater performance and efficiency.
