What is Liquid Immersion Cooling?

Liquid immersion cooling is a cooling solution for high-density racks in server rooms (40-50kW) and datacentres that relies on heat reduction through the immersion of the server hardware in a dielectic liquid that can conduct the heat. A dielectic liquid for this type of cooling application should have good thermo-physical properties (high conductivcity and speciifc heat), low freezing and burst points, a high atmospheric boiling point, good chemical and thermal stability, high flash and auto-ignition points, be non-corrosive to materials including metals and plastics, have no or minimal regulatory constraints and be economically viable as an alternative to air-based and gas refrigerants.
