Data is powering dramatic changes around the world, in both business and quality of life. But as all that data is stored and processed in data centres, it comes at a cost in energy consumption, water use, real estate footprint and more. Today, 3M is a leader in the liquid cooling revolution for data centres. Our line of non-conductive and safe 3M fluids used in immersion cooling are ideal for data centres single-phase and two-phase cooling processes.
The future of efficient, sustainable data centres starts here. Watch the mini-documentary on the world’s growing demand for data, data centres’ growing demand for energy, water and real estate, and how the industry is working together to address these challenges.
Data centre immersion cooling involves directly immersing IT hardware in a non-conductive liquid such as 3M™ Fluorinert™ Electronic Liquids or 3M™ Novec™ Engineered Fluids. Heat generated by the electronic components is directly and efficiently transferred to the fluid, reducing the need for active cooling components, such as interface materials, heat sinks and fans that are common in air cooling. Liquid immersion cooling with 3M fluids can provide tremendous energy savings while increasing server density and shrinking data centre size.
Traditional data centres use an average of 40% of their energy just on cooling, plus billions of gallons of water. Explore a world where that could change, backed by new innovations in heat transfer and thermal management technology. (PDF, 3.15 MB)
New data centre immersion cooling technology incorporating 3M™ Novec™ Engineered Fluids, pioneered by Allied Control and The BitFury Group for Bitcoin mining, offers dramatic improvements in energy efficiency and sustainability – including up to 97% energy savings. (PDF, 2.15 MB)
Liquid immersion cooling using 3M™ Fluorinert™ Electronic Liquids or 3M™ Novec™ Engineered Fluids can contribute to a lower cost of ownership, by reducing both capital and operating expenses. Direct liquid cooling helps improve efficiency and reduce costs throughout the life of your data centre -- from design and construction, to maintenance and operations, and to repair and replacement of hardware.
The clearest advantage will be evident in your electric bill. The most efficient immersion cooling methods can help improve data centre energy efficiency (often the largest electricity cost for a data centre) by up to 97%.
The improved cooling capacity means you can position electronics closer together — so you can fit 10 times the compute density in a given space. This opens the possibilities of where you can put a data centre.
With greater thermal efficiency, you can increase processing power and reduce latency beyond the limits of air cooling.
Liquid immersion cooling eliminates airborne contaminants and simplifies thermal design to reduce moving parts. This means you can run your electronics at full capacity with less wear and tear.
Building a data centre that uses immersion cooling doesn’t compromise safety for your operator. 3M designs all 3M™ Fluorinert™ Electronic Liquids and 3M™ Novec™ Engineered Fluids to feature low toxicity, non-flammability and an overall wide margin of safety for workers.
Build your data centre where you want it to be. Immersion cooling using 3M fluids enables greater data centre design flexibility – allowing you to choose the ideal location for your data centre without environmental constraints such as hot and humid climates, pollution concerns or land and space constraints.
Saving energy is not only good for the bottom line — it’s good for the earth. Less power used means less need to generate electricity, which in turn means less fuel used and fewer emissions. Smaller data centres save construction materials and maintenance. If your goal is a greener bitcoin or cryptocurrency operation, 3M™ Novec™ Engineered Fluids make these outcomes possible and at the same time feature:
Server manufacturers, system integrators and data centre engineers all face similar challenges: Design and assemble a data centre that answers core customer needs in terms of cost, performance and reliability. Immersion cooling using 3M fluids can help you answer those, and other practical needs, without compromise.
Immersion cooling involves putting electronics directly in a non-conductive fluid, allowing heat to be transferred directly from components into the heat transfer fluid. In traditional cooling systems, heat must transfer through several levels of thermal interface materials, air, heat exchangers and working fluids. Immersion cooling simplifies thermal design and increases heat transfer efficiency.
Many factors should be evaluated when selecting a working fluid. 3M™ Fluorinert Electronic Liquids and 3M™ Novec™ Engineered Fluids have several significant advantages versus other classes of dielectric fluids, including mineral oil. In addition to being non-flammable and non-combustible, 3M fluids have the boiling points and thermal stability needed for two-phase immersion cooling operations. Servicing and maintenance are made easy, since the electronics come out of 3M fluids clean and dry.
Immersion cooling systems are typically designed to be serviceable and hot-swappable, but are also designed with fluid containment in mind. By following 3M best practices and purchasing from a 3M authorised immersion cooling OEM, fluid losses can be held to inconsequential amounts.
Vendors are already offering proprietary server and mechanical systems based upon this technology, with others in development.
Two-phase passive immersion cooling exponentially increases heat transfer efficiency from boiling and condensation of Novec engineered fluids. This simple approach features almost no moving parts.
In single-phase immersion cooling the fluid has a higher boiling point and remains in its liquid phase throughout the process.
Thermal management challenges and techniques come in a variety of forms, so the unique properties of our fluids can be applied in a variety of ways to solve those challenges. One such challenge is the complexity of applying direct-to-chip (D2C) water cooling, due to the risk of leaks and difficulty cooling a series of processors in the same circuit. 3M Novec Engineered Fluids are a compelling working fluid option in these applications.
