External Ice water cooling system

[Redfusion900]

Anyone thought of filling a cooler with ice water and running a small 12v pump with a y adapter to hook up to your pickups to cool the motor and ESC between packs and before a run? Curious of everyone's thoughts..

I believe a few people on OSE have tried this, from memory condensation was an issue with the esc.

Hmm.. being a supposed waterproof ESC I wonder how or where it would condensate. Theoretically it should be sealed from all internal condensation, in that case I would think it would be ok.

I usually have a large container/bottle of cold ice water and I just take a gulp and blow it into the rudder water inlet and watch it exit through the water outlet. Gets the motor and esc cooler but I do it slowly as in short bursts and let sit for about a minute before blowing more cold water. I don't know if it matters or not but I just don't want to cool it immediately. . . so by doing it in short bursts and letting it adjust slowly to the cold water I feel, imo, I don't shock my motor and esc if it even matters. I usually only do this when I have a bunch of kids waiting to get their turn or when I want to run that particular boat again and again. But I have 3-6 boats for the neighborhood kids to play with. . .lots of fun!

Why Ice water? Ambient temperature is sufficient. You don't even need a 12v pump, just use a 5 liter pressure sprayer.

Thats where I originally got the idea from.

Agreed, I just figured I could use the ice water to lower the temps prior to the run. That is what we did when I was running snowmobile grass drag setups.. pre and after cooling with ice water. In our hobby It seems to be accepted that a cooler ESC and motor have less resistance that they do hot. Hence the ice water.

Not all speed controllers are waterproof, if your running a fully sealed waterproof esc then condensation will not be an issue.

Yes but as soon as the boat runs again the ambient temperature water will just bring the temp back up and you could end up with the condensation issues. Don't forget that different metals expand and contract differently and the potential is there to create problems.

SAW racers do/did this, but after cooling everything we sealed the system since pond water would quickly warm things back up. It worked well without differential expansion issues, but this would not work for extended oval racing.

That's just plain silly........

Oh Wait

Here's another bright idea I experimented with (rather unsuccessfully) - fill tube with freezer pack blue ice, inline with onboard cooling setup to cool while underway. No bueno...........

Was relegated to the pile of other ideas that bombed such as the styrofoam turn fin & the edible propeller

LMAO!!! I've done the same thing in the past and even worse ideas that I don't care to share. .LOL I'm glad I'm not the only "genius" in fe boating. .

I use a USB powered submersible pump in a water bottle with ice, I run it with a small power pack phone charger. I only use it to chill the motor and it does an amazing job. I just got back from the Nats in Salt Lake and it got a good workout in the heat.

I prefer to liquid cool the driver.

I noticed it cut out just before Tyler bit the dust. LOL

[ray schrauwen]

I use it to cool down after if I've paddled the throttle too much. I just use a big syringe and suck up cooler water, saves packing too many things. Drinks need to be cool too ya know...

[RaceMechaniX]

I had forgotten about that slip. Those damn crocs turned into greased skids on that polished concrete table.

[SweetAccord]

Every time I see this subject I think of the Peltier plate. Has that ever been tried by anyone? If yes, what happened? If no, why not?

[pescador]

I have a small one for aquariums packed away somewhere, hmmm might be a winter project lol. Went thru lots of ice at the Salt Lake Nats.
