Flourinert + submersion chiller idea?

[iboomalot]

why would you use this expensive stuff. Use transformer oil. Much cheaper same s***t. It actualy has no freeze point

everything has a freeze point they just don't mention it since transformers are usually in a warm enviroment and are self heated.

I contacted them about the freeze point and the reply was it does not actually freeze but liquid viscosity gets higher with colder temps. I agree with you that at some point the viscosity would be so high that you can say that its frozen but that would be after -80c probably

Technically many materials do not have a freezing point, glass for instance. Just once viscosity gets infinate, its not too interesting as a fluid anymore
