This literature review reveals that immersion cooling technology can effectively improve the temperature control level, energy efficiency, stability, and lifespan of electronic devices. However, the high cost, safety hazards, and inherent defects of current immersion coolants restrict their large-scale application.

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 ...
Dec 1, 2022 · Immersion cooling is economical due to the fact that there is no need for fans (for certain types of immersion cooling) and the heat is well regulated. Moreover, traditional cooling techniques require a lot of space and contribute to the total cost of ownership.
Immersion Cooling: Near-Term Innovations and Future Directions. In our exploration of the evolving processor landscape thus far, we’ve delved into the increase in power and thermal output, emphasizing the growing challenges for traditional cooling tech-nologies. Immersion cooling has not only proven itself as a contemporary solution but is also
Jul 11, 2023 · Immersion cooling aims to reduce costs for both OPEX and CAPEX. For example, with a single-phase immersion cooling solution, you could see a 95% reduction in cooling OPEX. With a PUE of 1.03 (certified by a 3rd party), many will realize an ROI of less than one year, even considering power savings.
