Cool, Calm, and Connected: The Rise of Liquid and Immersion Cooling in Datacenters
Liquid cooling and immersion cooling are becoming increasingly popular ways to manage the heat generated by servers in datacenters. Unlike traditional air-cooling methods, which struggle to keep up with the rising power density of modern IT equipment, these liquid-based solutions offer greater efficiency and a smaller physical footprint. Understanding Liquid Cooling Liquid cooling, in its most common form, uses a fluid (often water) to directly cool components. This is similar to how a car engine is cooled. Instead of relying on fans to push air through the server, a special manifold or cold plate is attached to the heat-producing components like the CPU and GPU. The liquid flows through this plate, absorbs the heat, and then travels to an external radiator or heat exchanger to be cooled down. This method is highly effective because liquid is much more efficient at transferring heat than air . This allows servers to run at lower temperatures, which can extend their lifespan and improve...
