Immersion cooling in a dielectric liquid is the next step in data center cooling, as the electricity required for the aircon comprises most of the data center's power use. Immersion cooling reduces this by up to 70%. It can take several form factors; this is one, but also as seen at liquidcoolsolutions.com and midasgt.com. While ordinary mineral oil will work short term as a dielectric oil, it has problems with material compatibility, oxidation resistance and zinc whisker growth. As noted above, fluorinated fluids work well, but they're hugely expensive and are usually used in two-phase systems where the fluid actually boils and is condensed and pumped back to the components. An engineered dielectric coolant that's specially made for this application is the way to go.
