Thermoelectric Cooler (TEC) Modules

Advanced Thermal Solutions Thermoelectric Cooler (TEC) Modules are semiconductor heat or refrigeration units which use the Peltier effect to create a heat flux between the two surfaces of the module. TEC modules use two thin ceramic wafers with a series of P and N-doped bismuth-telluride semiconductor material elements sandwiched between them. The ceramic material on both sides of the module adds rigidity and the necessary electrical insulation. The N-element type material has an excess of electrons, while the P-element type material has a deficit of electrons. One P-element and one N-element make up a couple junction that creates the thermoelectric effect.
