You'll need some insulation or it won't be very efficient.  I believe the cold side of the pel device faces inside then a heat sink goes on the hot side of the device with a fan blowing across that to remove the excess heat.

But double check me on that because I've never used a p device.

 i am using a lot of insulation. it will really just be a pc case. the inside is going to be a fridge. insulation and everything.

 that plan with a pc case will be inneficient. If you are going to use peltiers, then you should look at one of the links to the right.

As for what you need, a heatsink and a peltier. The peltier works by one side getting hot, and the other getting cold. apply the cold side to the can, and the heatsink to the warm side
