Thermal - Thermoelectric, Peltier Assemblies


A thermoelectric (TE) module, or Peltier assembly, is a semiconductor-based device that moves heat from one side of the device to the other when low voltage DC power is applied. One face of the module is cooled while the opposite face is heated. This phenomenon is reversed with a change in polarity of the DC voltage. A TE module can generate current when a temperature differential is applied. They are differentiated by heat transfer type, cooling power, current, voltage, and overall dimensions.
