Thermal - Thermoelectric, Peltier Modules

Thermoelectric modules (TEMs), also known as Peltier modules, can be used as a cooling&heating or power generation device. They are composed of thermoelectric materials, usually bismuth Telluride or antimony. When electrically connected, they can move heat from one side to the other, depending on the current direction.

Principle of Operation of Thermal - Thermoelectric, Peltier Modules

Thermoelectricity, or the "Peltier effect" as it is more commonly known, is based on the concept of heat pumping. When an electrical current is passed through two wires, the heat is transferred from one end of the wire to the other. The wire acts as a bridge between the heat source and the cooler region. The current flow and the difference in temperature between the two surfaces determine the amount of heat pumping or pumping of thermal energy. When direct current is passed through the thermoelectric material, a counterflow of thermal energy occurs, and the heat is either transferred from one end to the other or vice versa.

Thermal - Thermoelectric, Peltier Modules Applications

Thermoelectric modules provide an efficient, reliable and economical method to transfer energy from one side of an application to the other. The most common application for thermoelectric modules is that of cooling. In fact, it is one of the most cost-effective and reliable cooling methods used today.Thermal - Thermoelectric, Peltier Modules are also used in the automotive industry for various applications, such as engine cooling and other aspects related to engine performance. Many other industries have adopted this technology, including medical device manufacturing, pharmaceutical manufacturing, computer and semiconductor cooling, and more.Apart from cooling applications, thermal - thermoelectric, Peltier modules can also be used for power generation applications. They are employed in hybrid and electric vehicles, solar power cells, and fuel cells as means to produce electrical energy from the heat generated by these systems. This is known as the thermoelectric power production or the “Seebeck effect”.

Conclusion

Thermal - thermoelectric, Peltier modules are effective and economical solutions for a range of applications. The Peltier effect can be used for cooling, while the Seebeck effect is used for power generation. Thermal - thermoelectric, Peltier modules can be used in a range of industries for both cooling and power generation purposes. With the increasing focus on green energy, thermoelectric modules will continue to be a popular choice for a range of applications.
