Default Peltier cooler on a motor?

round my track every one uses a peltier chip of some sort to cool their motors i was thinking why not run one on the motor during the race?
why hasnt this taken off? i heard bout some people in japan doing it but never saw pics or products?
i was thinking copper clamp and copper heatsink with a 30 mm much more fan hard wired to the pack any opinions?
would the weight out weight the speed gained? am i wasting my time?
cheers all

I think you will find not only the weight penalty but also the amount of current that the system would pull, would make it totally pointless to try and run this system during a race.

Peltier cooler pulls out a lot of juice.

So u would need an additional power source to run it.

Add all that together, it would be really heavy.

Just My 2 Cents...

Thermodynamcally, your not gaining anything.

You're using a device to remove heat from the motor which in turn needs to have the heat removed from it as well. All this while using power from the batteries that power the motor or other batteries on board that require extra power from the motor to carry the weight.

In the short run you would gain power from a cooler motor but in the long run all the losses from keeping it cool catches up. Unless you can prove that the power gained is so tremendous such that it outperforms the power lost.

Peltiers are also very fragile and fairly expensive. You crash proof?

The mid range peltier module in my motor cooler pulls 6 amps from 12volts so it wouldn't be useful to try and run it on the car, let alone the fact that the heatsink and fan I have on it make it look like a gas motor when it's doing it's thing
