Liquid Gases on Robot as coolant

Are you saying you want to submerge your circuit board in an open container of liquid nitrogen?

No, although I suppose someone might be capable of doing that. I was rather suggesting that pouring a rather minute amount of LN, or a similar supercooled, non-toxic gas onto the circuitry, and letting it evaporate in place of the circuits heating up, is technically the only feasible way to keep the circuitry cooled without completely enclosing the system, and thus removing most of liquid gas's benefits.

I'm not advocating doing any of this, aside from spraying it down with compressed air every so slightly before a match if circuit heating is a real issue, due to the extreme dangers of burning if it's mishandled and the usage is done poorly; just saying it could, ever so possibly, be legal.

Pouring liquid N2 directly on your circuitry will almost certainly destroy it.

Most likely. It's why I mentioned using canned air and spraying it upside down prior to a match, rather than storing it on the robot.

What could go wrong!

Well, at least it isn't electrically conductive.

Sure, it might make everything brittle and shatter, but at least you won't have a short!

how is your electronic board heating up in the first place, nothing should overheat except perhaps a breaker, batteries can get a little warm too i guess.

team 20 was actually packing ice on their motors (or i assume it was the motors) between the matches in the finals at BAE
