Ryu- This has been done before when a guy used a boat ESC in a vehicle. I'll try to find the thread on his build. He said it worked very well. He used a small pump that put out like 10psi and a small tank.

heat pipe

i have seen a pump small enough but i dont know were to get it

Ryu this thread is becoming a sticky- insane build and the disc brakes are too cool!

I think you are onto something with a tank/pump setup and my suggestion would be a windshield washer fluid pump. Any auto parts store will have multiple units to choose from, a small 3S lipo (like a 800- 1320mah) would provide the 12V. Only possible problem would be that these pumps are made for intermittent use. Check Edmund Scientific for some small project type pumps as you would only need very light flow to be effective.

We will need some video of this bruiser ASAP!

A larger nitro tank, some al tubing arranged in a zig zag pattern with possibly a fan to blow air over it, and a small pump would work well. As long as it is setup properly a water cooling setup would not be very heavy or very big, but finding a pump that can handle a beating may be a challenge. A car w/s washer pump would be a good choice, they are pretty sturdy, and you could mount it to the side of the nitro tank with some creativity. No sure what voltage to run it on, as they produce a fair amount of volume on 12v. Maybe 6v off a ccbec or something like that. If I get bored I may make something!

you can get a radiator.
and a pump http://www3.towerhobbies.com/cgi-bin...?&I=LXDJR7&P=7

I'm pretty sure thats the one the guy used... Good find!

no, he builds pumps with no moving parts. but he had a small 5 volt pump on his emaxx one time but i think it was from work though, so its not available to the public.
but that pump should work.
he also made his own radiator out of aluminum.
shoot i will just through in some pics

sorry guys no hands.... lol

Yeah emaxxnitro hit it right on the head!

go for someting like this:

http://www.thermaltake.com/product/L...5/cl-w0075.asp

it has all the needed components, and they're working the right way. and its not too big. you definately need a radiator. otherwise you're just pumping hot water around.

this thead is getting really cool...

redshift · 07.24.2009, 11:18 AM

That setup is cool florianz!

Seems to me there would be enough heat dissipated thru just some tubing and a tank with just a few ounces capacity however.
The radiator might be overkill as he probably won't be getting a 240 amp ESC white hot, and at $30 for the SIG pump and a few bucks for a small tank is the way to go IMO.

Ryu, you could even run a mix of water and alcohol, for example, for even better heat exchange.

you could put ice in the water to start cool,

florianz · 07.24.2009, 11:53 AM

the thermaltake set is around 100,- Euro. probably not all parts are needed and you pick just the needed parts, and you get that even cheaper in the us. I would NOT take a kind-of, self-made radiator.

as these gamer cpu's get bloody hot and that combos work well, I think this is the way to keep the esc ice cold. I think it's great that each layer of the esc has it's cooling, and that you could use that.

fluids have a higher capacity to take heat, that's why even Harley Davidson switched from air cooling to water cooling (like that more horsepower), same with Porsche. but I have to say the air cooled HD's look better...

Absolutely correct, and it should be noted that HD recruited Porsche to design that engine FOR THEM... because oddly Porsche's design team is not stuck in 1910

yep... 1910 lol... progress, what's that?!?

porsche actually designed the last two engines for HD. but porsche have some troubles now... just got eaten by Volkswagen. soon the Porsches wil be just faster VW's... but that's a bit OT

Jetdry makes an excellent coolant if you plan on running something like that. I use to build custom PC water cooling kits years ago. Done lots of research and testing on what works the best. JetDry is by far the choice. Also you could consider a Peltier based cooling system, they work so well that u can even have ice build up on one side of the cooling plate. Some videos here

This is a good example here on what u can do with it.

Its funny because u can make power with heat with a device like this.
