please explain..thanks
The peltier module is just a heat pump. When you apply voltage, it pumps heat from one side to the other. It only works when the hot side is kept sufficiently cool or the whole module just heats up. The closer you keep the hot side to ambient temp, the cooler the cool side gets.

The hot side is bolted to a heatsink and fan to dissipate the heat. The cold side is bolted to an integy Motor Jig with a copper shim to provide direct contact to the motor.

The heat removal capacity of my little heat sink and fan was limited, so the module ran cooler at 5V than 12 V.

At one time I had two peltiers in a computer to cool the CPU. Both peltiers were then water cooled to keep the hot side from heating up. They work very good if you can keep the hot side cooled down but it takes a very large heatsink to do it correctly, or some sort of water cooling. If cooled correctly they will actually form a sheet of ice on the cold side in a matter of seconds.

I just can't help but think it would be simpler to take the motor out of the car, put it into a zip lock, then put it on top of the ice pack in your lunch box until the next round.

Art, the motor cooler that guy makes is a nice unit. He CNC machines a heatsink clip, that snaps over the motor. The whole package is very nice and works good too. If you so choose ( depending on chassis) you can leave it cooling right up the last second. He machines custom made comm lathes too. ( really nice work). I will try get in touch with him, as his wife is due or just had a baby and is out of racing for the time being

Default Orlando Based Motor Chillers

Hey Tim, thanks for the good words. The guys at Superior saw this forum and knew I was being talked about and told me to post something. This motor chiller works off any 12V power supply, or 12V no less than 7amp gel cell battery. The unit pulls about 4-5 amps and *will not work* with a race pack so do not try it, it may ruin the pack!? The motor chiller will strap right to the motor still in the car, others just remove the motor chill it and then put it back in just before you race. Take a look at the Picture. To use the cold side of a Peltier chip you must remove as much of the heat from the hot side as you can. The move heat you remove the better proformance you will get from these chips. Right know I have two units left if anyone is interested in them they are $50 dollars plus $5 to ship them. Questions Email me ([email protected]) Tim, We had our little girl 11/25/03 she & Mom are doing just fine, how is Less's Baby doing? See ya guys after a little RC break.

Default Motor chiller SIZE??

Calvin, this does not stay on the car for racing, size is no issue. With these chips the bigger the heat sink and fan the colder the cold side will get. This chiller works great with about an hours use attached to the motor it chilled it to about 40-45 deg.

its simply just aluminium and a fan, it will not cool down to any certain temperature, it will only cool down to the surrounding temperature!

Actually Disaster999... It has a Peltier Chip in there too. The Pelitier chip is what does the removal of heat. And yes it works good. I think the biggest benefit is if you can attach the cooler to the motor, while still in the car, before you run, and unsnap it and run. Some chassis make it difficult to fit the cooler on it, while the motor is still bolted in.
