Liquid Submersion Cooling

What Does Liquid Submersion Cooling Mean?

Liquid submersion cooling is a procedure that involves putting hardware or other items into a temperature-conductive, but not electrically conductive, liquid.


This technology is commonly used in large, professional technology applications, such as data centers.

Techopedia Explains Liquid Submersion Cooling

Liquid submersion cooling is sometimes used in data centers and similar technologies. This process brings to IT the same principles used by geothermal systems to heat and cool buildings. Simply put, temperature transfer through liquid replaces the often troublesome process of heating and cooling internal air in order to heat and cool objects in a room or space. Liquid submersion can also provide much more immediate cooling than does conventional air cooling.

Scientists have found specific kinds of liquids that are not significantly electrically conductive in order to make liquid submersion cooling safe. Many of these include synthetic oils and other products specifically made for this purpose.

The liquid submersion cooling technique can be applied to various aspects of data center operation in order to handle the amount of heat that generated by servers and other hardware.
