Immersion cooling working fluids for voltage-changing power electronics applications
Immersion cooling allows power electronics to be efficiently and uniformly cooled by immersing them in dielectric fluids that are safe for electronic contact.
3M™ Novec™ Engineered Fluids 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.See products Product selection guide
A smarter solution than other cooling alternatives
Cooling power electronics using an immersion cooling system offers many advantages over the alternative cooling methods.
-
Air coolingImmersion cooling offers more consistent and efficient cooling than air, which allows greater density of electronic components — critical to creating smaller power electronics.*
-
Water coolingUsing water to cool power electronics requires significant complexity to ensure that the water doesn’t contact the electronics and create a short. 3M™ Novec™ Engineered Fluids are dielectric and safe for contact with electronics, simplifying the system.* -
Oil coolingThe various oils sometimes used for heat transfer in immersion cooling for power electronics are all flammable at some temperature and leave residue. 3M™ Novec™ Engineered Fluids are non-flammable, resulting in greater safety, and leave no residue, for easier maintenance.*

All the performance without compromise
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:
- Low environmental impact, with zero ozone depletion potential (ODP) and low global warming potential (GWP), compared with conventional hydrocarbon coolants*
- Strong regulatory compliance — not scheduled for restriction or phasedown
-
