Hebei I.T. from Shanghai produces a great lineup of Peltier elements. We decided to add the TEC1-12705 module to our catalog due to its small size and impressive performance.
We used the TEC1-12705 to chill a can of beer within less than 5 minutes from room temperature to perfect drinking temperature.
Such an element can also help with overclocking high-performance processors by colling them down to freezing temperatures far below room temperature.
How it works:
As soon DC voltage is connected to the [+] and [-] wires, the hot side of the element starts to heat up and the cold side cools down. The effect is similar to a heat pump.
To avoid overheating of the hot side, sufficient cooling is necessary and typically done by a combination of a heat sink and forced air (fan).
I assume you know this effect from typical electric cooling boxes. They usually have a fan inside to blow out the hot air, and a large aluminum profile inside to remove the warmth from inside the box.
The effect is reversed by changing the polarity of the connection.
