As the complexity and sophistication of electronic systems for defense and aerospace, Hi-tech Data Centers, Cooling Transformers, Radars
applications continues to grow, so do the challenges of managing heat generated by these systems.
From the dense circuitry of today’s advanced avionics and electronic countermeasures devices to the tightly-packed power electronics of
commercial fly-by-wire systems, more and more heat is being confined to ever-smaller spaces.
Removing this waste heat is critical, to help ensure battlefield survivability and to maintain reliable performance in extreme environments – from gritty desert heat to the icy vacuum of outer space.
3M™ Novec™ Engineered Fluids and 3M™ Fluorinert Electronic Liquids are unique dielectric materials used to solve a wide range of thermal
management challenges. For example, 3M fluids can help reduce component bulk and weight; simplify design; and ensure system reliability, by
eliminating the need for fans and cold plates in many applications.
These clean, colorless, high dielectric strength, chemically inert fluids also offer a number of important advantages over other dielectric coolants such
as PAO (polyaliphatic olefins) and silicate esters, including:
- More efficient heat transfer properties
- Low toxicity, non-irritating
- Non-flammable and non-combustible
- Stable at temperatures up to 300°C
- Maintain low viscosities at temperatures down to -80°C
- Low latent heat of vaporization. This is an important consideration, because in the event of a
leak, oil-type coolants trap dirt, and are difficult to clean up. 3M fluids evaporate quickly and
completely, leaving no residue. Due to the fact they are inert, 3M heat transfer fluids will not
interfere with the operation of other devices, should a leak or spill occur.
- Inert to common and even dissimilar metals.
- Compatible with all hard polymers and a variety of common elastomers
- Will not hydrolyze or degrade over time to form deposits that can occlude fluid passages
3M™ Novec™ Engineered Fluids and 3M™ Fluorinert™ Electronic Liquids are compatible with
a wide variety of materials used in heat transfer equipment. As with any design, selection of these
materials is very important. Our tech support can help you make the proper choice.
Most of the materials commonly considered “hard” plastics will perform well with both Novec
fluids and Fluorinert liquids.
Elastomers should be limited to those that are not heavily plasticized. 3M engineers can assist
you with recommendations and testing on specific compounds.
