If you build a custom metal box big enough for a couple of cans then stick a couple of peltiers on the outside, (covered in heatsinks) they should cool the box nicely, If you put ice inside the box with the can the peltier should assist in keeping the ice frozen. I.E. The peltier's not doing all the work. Then if you enclose this box in another slightly bigger box you can place a couple of high CFM rated fans to blow cool air around the outside (hot side) of the peltiers. If you'r really imaginative you could blow cool air from inside the cold box around the "Cavity" to cool the peltiers even more. This is the plan I have for my own cooler. I will post a picture tonight when I can get FTP access to the server... *mumbles* Damn work proxies.. *mumbles*
do you need to cool more than 1 can at a time? if not, 25-30 for a premade single can cooler isnt that bad.. well when you consider the cost of pelts, the cheapest ive seen them is like 12$ each for small used ones from bgmicro.. plus you would still need heatsinkage and fans.. lissin to me, i sound like a damn sales person.. -scoob8000
lol, i'm amazed on how many replies are on here, but i can't order that thing 1. no money 2. they dont ship it to belgium (goddammit) Maybe someone else use my idea and bring it out :dude:
If you place a smaller fan in the inner box blowing cold air out by the intake fan it should blow slightly cooler air throught the cavity helping to cool the peltiers that little bit more.
Bit of a design change, instead of the cavity been a U shape it would be an L shape, the hot air should expel out in line with the peltiers, if it was to travel up and out of the fan as in the picture above it would warm the side of the cavity. Now i suppose you ask why not just have fans on one side blowing in and out on the other flat on the base? Remember you'll want to pump in some chilled air!
