what amperage do these things pull for the amount of voltage you are putting into them

Honestly...With proper ventilation, you wouldn't need the fan on the Heatsink.

The main problem I see is this:

Depending on the wattage rating of the Pelt, you're gonna cut into runtime severely if you want it to work well.

I'm a hardcore PC overclocker and moderator at XtremeResources.
While Pelts are great for PCs, you're gonna have to get it smaller and more energy efficient to be of ANY use on an RC car.

As it stands now, any advantage you gain by having a colder motor may be used up lugging the extra weight of the cooler around the track.

Soviet....

You're right.... BUT...

They're using these to cool the motors before a run. Not during. They're being powered by 12 volt power supplys, not batteries. Look at the pics.

The "SuperCooler" pulls aprox. 6.5 amps at 12VDC. and will operate up to 14VDC(the fan may fry), But there is little performance gain.
I have made car stands and battery cooling trays and malted barley beverage coolers, the possibilities are endless.

O.K.
Soviet, the "SuperCoolers" are ment to be used as "pre-race" motor coolers, also for after race cool down.

I just find it funny someone thought the one that is for xrays actually is used on the car while it runs.....bet that thing has killer rear traction!

OOPS!!!

Egg on my face!


I was just so excited that other folks were using peltiers that I didn't notice that they were meant to be stationary.


Hmm...now it has me thinking....What if you COULD make one that worked while running...

Actually, just wondering...

How much difference can you get by cooling the motor with the Pelt cooled berfore running??? How long it can maintain the power of the motor till it hits the drop zone???

Hi Speed Demon,

I have used a peltier for an year long, OK, not so many races, due to professional workload, but the experience I have show me the following:

1. With my peltier pulling 8A at 13,8V the motor reached -2C after 45min with an exterior temp of 30C

2. The first 3 or 4 first complete turns were incredile in terms of top speed and power (several times I jumped from the middle of the grid to number 1 before the 1st bend)

3. After 5 to 6 turns the motor is like any other, so no more difference

4. At the end of the race normally it was 10 to 15C cooler (measured with an infrared probe)

5. No effect on batteries

Wouldn't it be easier to just put some ice on your motor can? Or am I missing something?

Hi ozoner,

You're right. But with ice you have to deal with water.
I think that if you don't bother to take out your motor every time, the easiest and most effective way is to put it on a plastic bag and through it on an ice pot.

Trust me, once you use the peltier device, you will never want to use ice again. Much easier to use, to gets the motor colder, you don't have to worry about carrying ice around or getting water on the electronics of your car. Plus it is much cooler to use.
