Thermoelectric Cooler Power Efficiency

For many years the main three semiconductors known to have both low thermal conductivity and high power factor were bismuth telluride bi 2 te 3 lead telluride pbte and silicon germanium sige.

Thermoelectric cooler power efficiency.

The efficiency of a given material to produce a thermoelectric power is governed by its figure of merit zt s 2 σt κ. The efficiency of a peltier element application depends on the coefficient of performance cop which depends on the operating point the thermal design and the tec controller supply type. Thermoelectric wine coolers are more efficient at cool and use less electricity. 5 100 hp 5 640 watts hp 15 efficiency of thermoelectric material 13 2 volts 181 amps available for.

Improved materials would not only help to cool advanced electronics but could also provide energy benefits in refrigeration and when using waste heat to generate electrical power. If a unit was built to capture as much heat as possible say 50 of that. Tec controllers are used for thermoelectric cooling and heating in combination with peltier elements. All three points are discussed in this article.

Such an instrument is also called a. 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. Thermoelectric cooling uses the peltier effect to create a heat flux at the junction of two different types of materials.
