This is a geek project, to recover a few major parts from a scrap PC to make a clamp on cooler to chill a highly caffeinated beverage. The aim is to take a canned drink at room temperature and cool it in less than 5 minutes to a crisp, refreshing 8 degrees Celsius.

Pictured above is the heat sink and fan assembly from a Compaq Evo. It promises to add an interesting steam-punk edge to the project, if carried through creatively. We still need to recover a Peltier cooling chip and sandwich it and some thermal paste between the heat sink and a can sized copper clamp and then power everything off a reclaimed PSU.

The Peltier chip is typically inserted between a the microprocessor chip and it’s heat sink. Pentium’s need them to cool off and from my perspective, what better use of a Wintel box than to scrap it to chill a keg of beer? Ok, ok, the project to make a bigger cooler for a 5 litre mini keg of Heineken is just an idea, so let’s not get ahead of ourselves. My next project is probably the corollary of the Peltier effect: The Seebeck effect. Which is about applying heat to the chip and harvesting the electricity it produces.

Scrap parts to recover: A heat sink, large, preferably with mounted fan, a Peltier chip, a PSU. Other tools and parts required: Tools, nuts, bolts, washers, solder, thermal paste, lock nut glue etc.

This initial project proposal will be expanded in the execution phase with more on the design, assembly and, finally, the thirst quenching testing.
