Peltier Coolers

A Peltier cooler is a small device that is usually put in between a CPU and its heat sink. This is because a Peltier cooler is far more efficient at cooling a CPU down than a heat sink alone. The tec1-12710 and 12709 that where mentioned on my previous post are almost identical except that the 12709 is a lower power than the 12710.

The Peltier coolers are named after the  Peltier effect, a product of the thermoelectric effect. I am not going to go  into detail about either but I will give a brief explanation of how the cooler works. When a temperature gradient is applied to a thermoelectric device a voltage is created. As is often the case in physics what works one way also works in reverse. When a voltage is applied to a thermoelectric device a temperature gradient is created causing one side to be cold and the other hot.

This is the basic overview of how a Peltier cooler functions. I hope this proves useful 🙂
