Default Thermoelectric Motor Cooler

Does anyone use these for dirt racing...... I am asking because with outside temps at 90 ~ 95........ I am taking my motors off the track at 200 or so.. (12x2 in a FT B4) I have also had problems with my brushless... I just got it back today (neo 1 star) I think that might have been a heat thing to....

Thanks for any help with this...

Thermoelectric as in a peltier style cooler? Peltiers are the most horribly inefficient cooling methods, you'd be better with a fan.

I think that is what they call them.....


I thought you put it on..... cool the motor way down, and right before you go race you take it off.... then you start the race with a motor that is like 30 ~40 degrees...... so it is not as hot when you are done........


that is how i thought they work.... but please correct me if i am wrong......

I think it's a ''Much More'' brand of cooler that Cory has.
He put it on before his Main and,that motor was Cold! like touching Ice.

Thermoelectric coolers, AKA Peltier coolers/devices, are effective when used to PRE-COOL an electric motor...much different than on-board cooling. A lot of TC racers use both a Peltier for pre-cooling and then a fan (or two or even three) for on-board cooling. If you run 4wd on a high bite off road track, I might consider a thermoelectric cooler useful...or maybe even stock or 19T in a 2wd/high bite situation.

I recommend the Crazy RC model...it features a much thicker copper base and copper clamp (which results in more effective cold transfer) than any other one commercially available.

J.Filipow: I didn't know about the pre-cooling, for that yes the Peltier/Thermoelectric is fine, since you have no worries of powering a down car.

Some things about TEC coolers

1. One side gets very cold while the other gets very hot, you'd need a heatsink fan on the backside to keep it from frying.

2. They draw huge amounts of power, high end PC TEC's can eat around 300Watts.

3. Condensation can be an issue on the cold side.
