Thermoelectric Cooler Power Efficiency

Thermoelectric cooling uses the peltier effect to create a heat flux at the junction of two different types of materials.

Thermoelectric cooler power efficiency.

If a unit was built to capture as much heat as possible say 50 of that. Because of the peltier effect these coolers have less moving parts which means they require less power than a compressor cooler would. 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. 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.

All three points are discussed in this article. Advantages of thermoelectric wine coolers. Such an instrument is also called a. The principles of thermoelectric devices are reviewed and strategies for increasing the efficiency of novel materials are explored.

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 wine coolers are more efficient at cool and use less electricity. The efficiency of a given material to produce a thermoelectric power is governed by its figure of merit zt s 2 σt κ.
