This is perfect for the gamer who goes all day and doesnt have his own mini fridge. With a bunch of crap you probably have lying around you can make a working drink cooler. The process is real simple.

Step 1: Find yourself a heatsink. Any one will due, I used one from my A64 2800+

Step 2: Run the fan wire through the front of your case (i went thru the hole in the botten, but an empty firewire hole shoudl also work), and find somwhere to plug it in. I had to use a 3-pin to molex connector to make it long enough, but i know my Venus 12+ had a chord that was really long, so just do whatever works best for you.

Step 3: Take a pile of tinfoil, and using any blunt object, hammer it into the bottem of a can so that one end is molded to the little dip int he bottem of the can and the other is smooth enough for good thermal contact

Step 4: Rip the flap off a cardboard box. Cut it to that its a bit higher than half way up the side if the can. Then cut it so that its just long enohgh to hold the can. Tape it together.

Step 5: Apply a coat of thermal paste to the tinfoil...make sure to give enough to get in all the cracks so you have a smooth surface. I found that the tehrmal paste alone was enough to keep the tinfoil it place, no need to tape it.

Step 6: Tape the carboard to the side of the heatsink and your done. Just to put this to the test, that can of pepsi in there was taken out of the fridge this morning, and my can is still cool at 8PM. Woohoo. One bit of advice, depite my pictures, dont use something crappy to support the fan. This is just a temp solution till I can find the feet. These are wobbly and I woudlnt trust my drink in them. Go to the store and spend a dollar on some feet just tall enough to allow the fan to pull air through.

Also, sorry aboutt he massive pics. By the time i realized they were so massive i didnt want to resize and reupload. Takes to long.

Wrong.... I stole it from the sceen savers who stole it from popular science (and even aired that exact image)....go figure.
 
Jeez those are some blurry pics. :eek: Btw, you have too much time on your hands lol
 
to much time? I think not. I spend more time finding the damn tape than I did putting it together. And yeah the pics suck, its got to be a four year old camera tho.

Did you read my entire thread. I dont have a real image host so I am stuck uploadig them one at a time to a free thinger. It takes waaaaaaaay to long, and I am a busy busy man who shoudlnt have wasted my time wiht this in the first place, but what the hey. If you dont like em, resize and host them for me, but I sure as hell aint gunan do it.

While that's a good idea, I don't have access to edit your post. :p

correct, but you can still give me links to resizes hosted images and I can resize them... if you felt it necessary.

he should start with learning how to focus


trust me, it has nothing to do with focus. Its a shitty camera. How about we not rape the picutres? Thanks
 
interesting stuff here. It seems teh base of the heatsink is cooler that the tinfoil. I suspect eihter tinfiol sucks at carying coldness or provides crappy contact, or thermal paste really only works tranfering heat. Eitehr way, I am trying to find another method. i think if I just set the can on teh heatsink base, it woudlnt really cool that well because there is nothing to tranfer the coolness, but i dont exactly want to lather all my drinks in thermal paste. I will tinker with it, maybe add a temp probe and see how cool my pops are getting.
 
Seeing as that's just an air cooler, wouldn't it just suck the cold away from the can FASTER? Seeing as how the can was prolly colder than room temp to start with, you circulating warmer room temp air around the can, heating it up. The only way these CPU coolers work is cause the CPU is warmer then the air around it.

Now a pelt rig WOULD cool it, but I seriously doubt this would keep you drink cool. If you think I'm wrong, please post your drink temps over time....
 
i have *got* to make one of those... hehe... i have an anodized aluminum hs from my father's busted tnt2 graphics card... now if i can only figure out what size fan to use...
 
Ok, Lets see if those years in college paid off...

The tin foil should be a Great conductor (aluminum) but my guess is that with all those nooks and crannies (ie. air trapped inside) the cold temperature is not being transfered at its best. I would pack the foil as compact as possible and make sure you get good contact surfaces to the heat sink and to the can.

The HSF will get the soda cooler than room temp (trust me on this one, moving air over fins will "steal" warmth from the fins, up to a point, of course) But if you get a REALLY cold soda.. well, its not going to get any colder on the HSF

This is a conductive cooler, the heat will always flow from hotter points to cooler ones. So there is no way the soda can be cooled to below room temperature using this setup.
 
Evaporation cools. So remove the heat sink. Its just blocking the airflow from the best conductive surface you have available, the can itself.

Wrap the can in a thin layer of cloth. Keep the cloth damp. And place it on top of the fan. This will be a chiller.
 
Rondu, ever heard of Thermodynamics 101? It is a nightmare of a class to every engineering student. You are right, heat disipates/moves from hotter to colder.

If you dont believe me take a themometer... its room temperature. Blow air on it for a minute... it gets colder!!! :eek: the fins just increase your surface area to help the exchange of heat.

Stunning.

That point is ROOM TEMPERATURE. Trust me on this one. If the fins are cooler than room temperature then the fins steal heat from the air. It works both ways.
 
Because the thread started was being a dick...

How well does this work anyway?

Exactly. Cold tends to go downwards and settle at the bottom of the can where the heat sink is warming the can up to room temp, making the can warmer faster.

This is very true but with a pelt in there it would tend not to matter that much. In fact this may keep the drink from freezing. A more efficient method may be to pour lead into the bottom of the can to make a casting.
 
it is pointless without a TEC. setup like that it can only cool a drink to ambient but it will do that by itself.

I've never tried this, but I would say that this would just warm the can faster. If this thing actually cools anything then I'm sure there are some physicists who would love to hear about it. An extraction of heat without any energy input is a pretty amazing feat.
 
I dont see how this cools.. if anyting it speeds up heat dissipation.. you have room temp air blowing more frequently over the colder can which increses surface area of room temp air over the colder can thus increasing heat transfer from room air to can.... even if the fins on the HS lower the room temp blowing on the can, it's still warmer than the can itself. considering we would think that a drink at, lets say 40 F is "cold". you would have to have air blowing at much less than room temp to actually have the can and liquid retain the "cold" properties.


or you could do what everyone else does and drink it fast
 
He is missing the crucial part: the peltier. This design does not work without the peltier to cool the can. The heatsink's purpose is to cool the peltier. I don't care that he claims the can stayed cool...at best it will warm up to room temperature and stay there.

Well all this people telling me otherwise is making me doubt myselft :confused:, i guess I will go home, read up a little bit and experiment some :)
