It's my own design. Peltier elements are available for $3-$8 on eBay. Connect it with a heatsink from a CPU and a CPU fan, put 12v 5a through it and the non heatsink side will be 20C cooler (about 35f).
Make a hole in a cooler and put the cold side into the hole. Insulate well and your cooler will be 20C cooler inside.
Now, if you add a heatsink and a low powered fan inside then it should cool faster.
If you put more Peltier elements cooling the hot side then maybe you might get a few more degrees coolness though the power used will be high enough to question the worth.
One guy built his own Peltier air conditioner!
