Peltier Effect

 

 

The Peltier effect is used in many applications for the reliable cooling of sensitive, high-temperature components without the need for refrigerants or compressors. Otherwise known as thermoelectric coolers, peltiers are a special type of semiconductor that function as a solid state heat pump. By applying a low voltage DC power source to one side, heat is moved in the direction of the current (+ to - ). The heat is thus pumped from one side of the module to the other, so that one face will be cold while the opposite face will be heated. The Peltier effect is named after the French physicist Jean Charles Athanase Peltier.
