Freon, good or bad.

Ok, I had this idea after watching Burn Notice on USA (good show, check it out). In the show, they use a compressed air can (liquid freon), sprayed upside down, to freeze a lock, then broke it like a rock with a hammer. So I tested it on a cabinet handle in my kitchen. The metal stayed cold for like an hour, in 80+ degree weather.
So my question is, would this work on a heat sink (the metal one), and would there be any adverse effects.

Re: Freon, good or bad.
the extreme temperature changes (negative when you spray, and positive when you run it) may/will cause the metal to warp, crack, and/or get brittle. Do not do this, especially if you're running a motor with ball bearings.

And technically its not you getting drunk, its oxygen deprivation, which can kill you fast.
So, materials?

ur actualy not supose to put dry ice in a freezer cuz its so cold that it messes up the thermostat of the freezer and ends up breaking it. but yea dry ice is some sweet stuff. drop a chunk of it into a bottle of vodka and suck down the smoke that comes off of it and u get drunk. its fun. lol
Fun? I would say dangerous.

Re: Freon, good or bad.
Think about who you're talking about for a sec.
Any ideas on materials?

Dry ice is actually frozen CO2. you suck down the 'smoke', which is actually CO2 vapour and you end up displacing the oxygen in your lungs. This is called oxygen deprivation and it could actually KILL you.
so please; use your brain and don't do it.

Wow, fail.
Still working on the holder, there's some space limitations and structural concerns.

Re: Freon, good or bad.
Well, you wouldn't be using FREON since it has been replaced by other regrigerants. Freon is nasty stuff to the ozone layer. Not something you want escaping.
People do cool down motors and heatsinks before and after runs. The pro's take every little gain that they can get.
Now this will only shave off maybe a few 10th's of a second from lap times. You will not see a big performance boost by doing this.

Re: Freon, good or bad.
After a hard run it's not a bad idea. I used the same thing to cool down my motor after races. Just make sure you take the batteries out or unplug the liths (if you have them) before hand to avoid shorts.

Re: Freon, good or bad.
Yeah, but isn't it better to have a cooler running motor?

Re: Freon, good or bad.
I think the idea behind the heat sink is to allow transmission of hot air into the atmosphere...by making it really cold don't you think you might block the heat transmission?
I don't know really. I don't think you'd gain much benefit from it.

That is why you put it in a cooler, it insulates the dry ice. Have fun killing brain cells breathing in CO2 though. Darwins theory works well with you.
