For a comparison of ElectroCool and 3M's Fluorinert please go here: https://www.engineeredfluids.com/slic-cooling-for-electronics
Weight: The weight of 3M's Novec fluoridated fluids is significantly higher than ElectroCool or AmpCool (1.6 g/cc Novec vs 0.80 g/cc for AmpCool). Novec's additional mass/weight is a huge disadvantage in aeronautical or electric vehicle applications, where the added weight effectively reduces the power and range, as well as greatly influencing weight and balance.
Toxicity: ElectroCool and AmpCool Dielectric Coolants are biodegradable, non-toxic and classified as Food Grade by the US National Science Foundation. All of our Dielectric Coolants have very low vapor pressures so there is no vapor generated during operation and no evaporation, making them well suited for open and sealed system operations. Both AmpCool and ElectroCool have a “0” Global Warming Potential. Compare this with the toxicity of halogenated solvents, like Novec. Novec fluid and its vapors are toxic, non-biodegradable and has a high Global Warming Potential between 275 to over 9,000 depending on which Novec product is measured.
Cost: The cost of ElectroCool or AmpCool is <15% of the cost of 3M's Novec Fluids. Be sure to keep the lid on your Novec or you'll be losing 1,000's dollars an hour in evaporation.
What happens the device is overheated? If there is a thermal runaway or over-temperature event with a semiconductor or battery, a two-phase fluid or a low boiling point fluid as Novec will vaporize and either boil away or create a high pressure situation which the system which must then be vented to prevent explosion. When this happens, then the device is left fully unprotected, as all of the coolant has boiled away. ElectroCool and AmpCool o not boil, and in an over-temperature situation, our Dielectric Fluids will continue to absorb heat and protect the other cells of the battery.
