Thermoelectric cooling uses the Peltier effect to create a heat flux at the junction of two different types of materials. A Peltier cooler, heater, or thermoelectric heat pump is a solid-state active heat pump which transfers heat from one side of the device to the other, with consumption of electrical energy, depending on the direction of the current.
The Peltier effect can be used to create a heat pump. Notably, the Peltier thermoelectric cooler is a refrigerator that is compact and has no circulating fluid or moving parts. Such refrigerators are useful in applications where their advantages outweigh the disadvantage of their very low efficiency.
Thermoelectric temperature control is the use of the thermoelectric effect, specifically the Peltier effect, to heat or cool materials by applying an electrical current across them. [1] A typical Peltier cell absorbs heat on one side and produces heat on the other. [1] Because of this, Peltier cells can be used for temperature control. [1]
Thermoelectric materials can be used as refrigerators, called "thermoelectric coolers", or "Peltier coolers" after the Peltier effect that controls their operation. As a refrigeration technology, Peltier cooling is far less common than vapor-compression refrigeration .
When the same principle is used in reverse to create a heat gradient from an electric current, it is called a thermoelectric (or Peltier) cooler. Thermoelectric generators could be used in power plants and factories to convert waste heat into additional electrical power and in automobiles as automotive thermoelectric generators (ATGs) to ...
Thermoelectric cooling uses the Peltier effect to create a heat flux between the junction of two types of material. [77] This effect is commonly used in camping and portable coolers and for cooling electronic components [78] and small instruments.
