The ability to precisely control electrical voltages on a large scale has made possible many efficient, powerful innovations, from high-speed electric trains to wind turbines to electric drive motors for everything from heavy earthmoving equipment to personal electric vehicles (EVs). But the equipment that manages this process — including power inverters, thyristors and variable-speed drives — requires high-performance power electronics cooling.
At 3M, we developed our 3M™ Novec™ Engineered Fluids to act as excellent immersion cooling working fluids for voltage-changing power electronics applications. These dielectric fluids are safe for contact with electronics and efficiently and uniformly cool power electronics using single-phase or two-phase immersion cooling. They offer wide operating temperature ranges, have excellent materials compatibility and are simple to maintain, making Novec fluid-based immersion cooling an excellent alternative to air, water or oil-cooled systems. And they do all this without compromising worker safety or environmental sustainability. As you develop the electric-powered machines of the future, turn to 3M Novec advanced cooling technology to help keep them cool.
Power electronics move the world forward. 3M has decades of experience cooling power electronics with 3M™ Fluorinert™ Electronic Liquids, and now our next-generation Novec fluids can help keep them cool through simple, efficient, high-performance immersion cooling. With significant advantages over existing cooling methods, consider the potential of Novec fluids for your power electronics cooling systems.
Electric-powered high-speed trains are transforming how people travel long distances safely, quickly and with significantly lower environmental impact than flying or other comparable modes of transport.
Earthmoving equipment can literally move mountains but requires enormous energy and power. This can be delivered efficiently via electric and hybrid drive systems controlled by power electronics.
Harnessing wind energy requires a complex transformation of mechanical energy — which itself varies with wind speed — into electrical energy suitable for the electric power grid.
The bottom of the sea is a challenging environment for power electronics, which are used in high-volume pumps that make petroleum extraction more efficient.
Designers of skyscrapers need to take people to new heights quickly. New high-speed elevators are designed to make living and working in tall buildings more convenient and comfortable.
The promise of electric vehicles depends on the mass production of efficient, reliable drivetrains that use power electronics to transfer energy from batteries to wheels.
As electric vehicles grow in popularity, the demand for widespread, easy to use rapid charging solutions is increasing in parallel. ITT Cannon developed a DC high power charging cable connector system, cooled by Novec Engineered Fluids, that enables a 60-mile charge to be delivered to an electric vehicle in as little as three to five minutes.
The Novec-based liquid-cooled charging cable connector allows ultrafast charge (500A at 1000V) while minimising the cable diameter for a flexible, ergonomic system that is as easy for drivers to use as a gas pump. Plus, Novec fluids offer:
We developed 3M Novec Engineered Fluids to excel in heat transfer applications. Through our work with leading manufacturers of power electronics, we understand the demands placed on heat transfer fluids used in power electronics immersion cooling, and we offer products that feature:
3M Fluorinert Electronic Liquids have been used for immersion cooling of power electronics for decades, and 3M now can apply that experience to the application of 3M Novec Engineered Fluids as well. Contact us for help choosing which product best meets your specifications and goals.
Using Novec Engineered Fluids in your power electronics cooling system offers many advantages over the alternative cooling methods.
Immersion cooling offers more consistent and efficient cooling than air, which allows greater density of electronic components — critical to creating smaller power electronics.
Using water to cool power electronics requires significant complexity to ensure that the water doesn’t contact the electronics and create a short. Novec Engineered Fluids are dielectric and safe for contact with electronics, simplifying the system.
The various oils sometimes used for heat transfer in immersion cooling for power electronics are all flammable at some temperature and leave residue. Novec Engineered Fluids are non-flammable, resulting in greater safety, and leave no residue for easier maintenance.
The Novec promise is performance without compromise. Our engineers purposefully developed Novec Engineered Fluids with worker safety and environmental sustainability in mind. These fluids feature:
