The thermoelectric cooling (TEC), also called the Peltier Effect, is a solid-state method of heat transfer through dissimilar (P-type & N-type) semiconductor materials.
The complete system includes a semiconductor module (P & N semiconductor clamped with two ceramic chips) and an internal/external heat exchanger. High-efficiency, low-noise fans are often fitted to optimize energy efficiency.
During operation, direct current causes heat to be transferred from the endothermic joint, resulting in an ideal cooling compartment for sensitive electronics or medical storage.
