TEC Electronic Thermoelectric Cooler Peltier

TEC Structure
A Peltiermodule consists of semiconductors mounted successively, which form p-n-and n-p-junctions.
Heat is absorbed at the cold junction by electrons as they pass from a low energy level in the p-type element, to a higher energy level in the n-type element. At the hot junction, energy is expelled to a thermal sink as electrons move from a high energy N element to a lower energy P element.
A module contains several P-N couples that are connected electrically in series and thermally in parallel
