Thermoelectric coolers (TEC or Peltier) create a temperature differential on each side. One side gets hot and the other side gets cool. Therefore, they can be used to either warm something up or cool something down, depending on which side you use. You can also take advantage of a temperature differential to generate electricity. The thermal tape listed below works very well to attach heat sinks to the hot side.

This Peltier works very well as long as you remove the heat from the hot side. After turning on the device, the hot side will heat quickly, the cold side will cool quickly. If you do not remove the heat from the hot side (with a heat sink or other device), the Peltier will quickly reach stasis and do nothing. We recommend using an old computer CPU heatsink or another block of metal to pull heat from the hot side. We were able to use a computer power supply and CPU heatsink to make the cold side so uncomfortable we could not hold our finger to it.

We recommend using this module at 12V, when used at this voltage it won't draw more than 5A. This coolers limits are slightly higher (~15/7A) but we wouldn't recommend getting close to these limits without extreme caution.

Note: It is imperative that a heat sink is used on the hot side of the module. Running the module without one can cause damage to this part. If it's too hot to comfortably touch, you're in the danger zone!
