what is a simple way to make an cooling mechanism?

i want to make a simple cooling mechanism(not talking about a fan here) which is simple to build, as little mechanical(moving) parts as possible, i don't have a huge budget...

submerge whatever you need to cool in mineral oil. get it at the hardware store. it's cheap and won't conduct electricity. heat on the other hand, will be convected away wonderfully.

put it in the refrigerator.
A Peltier cooler is a very neat invention, but for many applications it's still far too complicated. (You need a properly attached and sufficiently large heat sink and perhaps a fan.)

Instead, I suggest you take a look at evaporative cooling. You can buy polyacrylate powder on Ebay for $1.31/oz or less, or even use something as simple as moist sand or a wet towel.

What are you trying to cool? If it is a Processor then you would need something not too wide and tall, if you where cooling some building you would need something else...
