Noun
Peltier effect (plural Peltier effects)
(physics) A thermoelectric effect which occurs when current is passed through a thermocouple causing one side of the Peltier to heat up and the other to cool down, used in computing as a cooling process.
A continuous transfer of heat is necessary because the current flowing through the thermocouple tends to cause the hot side to cool down and the cold side to heat up (the Peltier effect ). Source: Internet
Thermoelectric refrigeration Thermoelectric cooling uses the Peltier effect to create a heat flux between the junction of two types of material. Source: Internet
