A thermoelectric cooler (TEC), also referred to as Peltier element, is a single-stage or multi-stage thermoelectric battery of thermocouples connected in series or in parallel. The so-called Peltier effect is generated when electrical current flows through the thermocouples in the TEC; this causes cooling on one side of the TEC while heating is caused on the other side. The change of polarity of the electric current supplied also changes the direction of heat flow. Thanks to this circumstance, the temperature of the object to be cooled can be precisely maintained when the ambient temperature changes or thermal output is released. These beneficial properties of Peltier elements are widely used for temperature stabilisation of temperature-sensitive elements e.g. in laser technology and radio electronics. They are used in all areas in which cooling is required with high reliability and small dimensions without using any moving parts.
