Description and Explanation of Open Bath Immersion System

Single Phase Immersion System  

datacenterchiller-immersion-system2Description and Explanation of Open Bath Immersion System cooling, is the use of submerging servers, or computer components in a thermally, but non electrical liquid. Many of these immersion systems have a different coolants, restrictions, and vary in size. Immersion cooling is growing in popularity among the IT community. A particular example of immersion cooling, is called open bath immersion cooling or semi open bath cooling. This form of cooling is used data centers and composes of single phase and two phase.


Single phase immersion cooling uses a liquid coolant that always stays in a liquid form. The liquid is a dielectric coolant. A dielectric coolant is a medium that is able to transmit an electric force but does not involve conduction. Examples of dielectric cooling, are mineral oil or deionized water system. The coolant fluid makes contact with the heated hardware, which is immerged in the bath. The heated hardware raises the temperature of the fluid via conduction. Once heated, the fluid is pumped to a heat exchanger. The heat exchanger cools the liquid and then transferred back to the open tank. One type of heat exchanger can be a cooling tower. Single phase systems are cheaper to maintain, lower coolant costs, and has little issues with vapors and coolant evaporation.
