The Science Behind Thermoelectric Cooling
Thermoelectric cooling operates on the principle of the Peltier effect, discovered by Jean Charles Athanase Peltier in the 19th century. When an electric current flows through a junction of two different conductive materials, heat is either absorbed or released, depending on the direction of the current. This phenomenon is the foundation of how thermoelectric coolers function.
The core components of a thermoelectric cooler are thermoelectric modules made of semiconductor materials.
