just saw a thing like this in pop sci…
pretty cool concept (esp. when applied to pc cooling)

i like this idea, i just wish it didnt take so much power to cool, at 80w, that peltier is pulling 6.6A, thats alot.

Indeed… it also pwns your digestive system too o.0 :P

he should have gotten a pharmisudical grade steel bolt. or what ever grade they use in dairy plants.

as if he didnt expect that bolt to degrade.. as soon as i saw it i was like “well i hope he washes it, sterilizes it and coats it with sumthin” buuut nope.. well a little iron is good for ur diet

well afrotech’s would of only been able to cool to room temp anyway.
and i have been looking for this exact idea of using a pelter as a drink cooer. his looks almost exactly the same as the plans i drew.

Mattt did this on the bit-tech forums a while ago.

i did this 11 years ago – 1995! bought a surplus peltier from american sci & surplus on a trip through chicago. no pwm, just straight 12 volts. otherwise it was very similar to the design above. guess i could have made millions…

I like this idea, however I think if I were to build one I would focus on the cupholder part a bit more. Being partial to cans, I would use a conductive material next to the peltier shaped to hold a fluid – probably water. The water would of course have excellent contact with the walls of its container, and would act very well as a regulator, absorbing heat energy from the can and slowly transferring that heat out through the peltier. A thermostat would allow you to leavet he peltier on all the time, keeping the water cool. When warm can was added, the water would be able to absorb heat more quickly than with the peltier alone. The buffering action would go a long way toward a faster result. Getting fancy, you could use salt water cooled to just below zero degrees celcius. If you wanted to keep the can dry, an inner sleeve would be simple enough to add.

By separating the peltier from the drink to be cooled with a cooled fluid, you could quickly adapt the range of the machine. You could vary how fast the cooler could work as well as its can capacity by simply adding a larger supply of water and/or more peltiers since they wouldn’t need to be in contact with the can. A CPU water block and pump would be ideal for this purpose.

and you can use a refrigerator too!
