Liquid Cooled Brushless System - Goodbye Fans? - RC-Monster Forums

Anyone seen this yet? Liquid cooling system for brushless systems. Neat idea!

Seen it and thought it was rubbish. The graphs are really misleading. Water cooling has worked wonders in computers but I still think it has a long way to go until a worthwhile and inexpensive system is available to R/C cars.

WOW! That is a great idea. I have thought of something like that before, but a pump was the problem...Looks like they solved that problem with there micro pump...I'm be getting one of these for my BPP LSP :D. One question though. Do you know what the difference is between the BL setup and the brushed one? GREAT FIND!

EDIT: Nick, why do you say that? It makes sense...The plate is cooled, thus not letting the motor plate get hot and retain heat so the motor stays cooler. Maybe I'm wrong though? Anywho, I think its worth a shot...

I didn't say the idea was bad, it's a good idea but the information/graphs they provide to prove it don't look good.

With twin fans, there is less than 10C temperature difference - in which, they do not provide any details about the fans. House fans? Ceiling fans? It could be of any RPM which is a real poor comparison. They don't say if it has heatsinks or not, which is another big factor.

So for £150 on something that is 10C different in comparison to the mystery "twin fans" with no description, or no heatsinks is over priced.

I think it would also add a lot of weight. good idea, but costly and weight wise, not sure.
The other ting that bothers me is, they state it gives the motor more power? How is that? I thought electricity ran better with warmth than cold?

The batteries produce better warm than cold.
The motor is better cooler.
You would need a boat style esc with the water cooling.
The pump is only 11 grams.

Makes sense. But you also have to figure in the liquid, lines to run it and so forth?

That little heatsink is not capable of serious cooling. If it can take off more than 5 degree C i would be surprised. (with our relative large motors)

The source of the heat is coming from the can, not from the front of the motor. Sure it will take of a bit of the heat, but that's one tiny cooler..!

Nick · 12.22.2006, 09:25 PM

I think a whole sleave for the can would be a good idea as cooling.

coolhandcountry · 12.22.2006, 10:32 PM

Need one like they have on the bk site. It wraps all the way around the motor.
The radiator would be nice to help keep it cool though. But wouldn't that be like having a finned heat sink.

Yeah, watercooling is normally used to transfer heat from a place where you don't want it or can't cool it.. I think it's pointless to use watercooling in RC, unless you build in the motor in a tight place.

WAy to expensive too, rather spend couple of bucks on a the rcm heatsinks and a cuple of nice fans.

coolhandcountry · 12.23.2006, 04:53 PM

I think it would be nice if the radiator had more surface area than a heat sink did.
Then it would be a benefit.

Nick · 12.23.2006, 06:07 PM

Maybe one of those mini fridges to put all your electrics in, run it off 12v, that should do the job nicely.

Serum · 12.23.2006, 07:02 PM

Bashing the fridge gets a whole different meaning then..
