- Immersion cooling is an IT cooling practice by which complete servers are immersed in a dielectric, electrically non-conductive fluid that has significantly higher thermal conductivity than air. Heat is removed from a system by putting the coolant in direct contact with hot components, and circulating the heated liquid through heat exchangers.

Immersion cooling is an advanced cooling technique used primarily in data centers and high-performance computing environments. In this method, electronic components, including servers and other hardware, are submerged directly into a non-conductive liquid coolant. This liquid absorbs the heat generated by the components, thereby efficiently ...
Dec 8, 2023 · Immersion cooling is a type of liquid cooling used to moderate data center equipment temperature by submerging it in a cooling fluid. Server immersion cooling helps to dissipate heat and keep components like CPUs performing optimally.
Mar 16, 2020 · Immersion cooling a.k.a. liquid submersion cooling is the method of submerging computer components or full servers in a thermally, but not electrically, conductive liquid.

Immersion cooling may well be the way of the future. The physics are very much in its favor as water is a far better conductor of heat than air. It is more than 20 times more efficient in transferring heat than air – and if you take a specific volume of water flow over a hot component (known as the volumetric flow rate), water has a heat carrying c...
Immersion cooling lacks formally agreed standards on what kind of fluids should be used. This is necessary as different chemicals deployed by OEMs within the immersion fluids may have a negative impact over time on the IT equipment they are cooling. “The fluids used in immersion cooling need to be inert, not degrade insulation, remove glues holding...
What about leakage? Yes, OEMs of immersion cooling solutions will go to great lengths to prevent it. But water will find a way, to paraphrase a famous line from the original Jurassic Park movie. Leaks could have devastating consequences to other data center equipment. Complete failures of immersion systems could flood the entire facility. This rais...
Most current data centers are ill-equipped to manage servers in an aquatic setting. Will staff need special wet suits and will they need to be trained and certified in diving? Alternatively, are cranes required above immersion systems to haul the servers out? Such issues need addressed in a way that doesn’t add complexity and expense. “Placing IT e...
Speaking of space, immersion cooling places plenty of constraints on data center design. Cranes need several feet of room above racks. Many data centers simply don’t have the room. Ceiling integrity is another challenge. Some will not be able to bear the weight of a crane hauling immersion systems around. Even without cranes, immersion racks are ty...
Despite these concerns, count on those on the leading edge of HPC and data center design to push the technology to the limit. It may take years until the wrinkles are removed, standardized solutions emerge, industry standards are issued, and prices come down enough to facilitate broader utilization. It remains to be seen whether liquid cooling can ...
