EFFET PELTIER by Etienne Perroux on Prezi Next.

See Article History. Peltier effect, the cooling of one junction and the heating of the other when electric current is maintained in a circuit of material consisting of two dissimilar conductors; the effect is even stronger in circuits containing dissimilar semiconductors.

What is the Peltier Effect? (with picture).

The Peltier effect is the basis for many modern day TE refrigeration devices and the Seebeck effect is the basis for TE power generation devices (see Thermoelectric Devices: Refrigeration and Power Generations With No Moving Parts).The versatility of TE materials is illustrated in Fig. 3 which shows a diagram of a thermoelectric couple composed of an n-type (negative thermopower and electron.The Peltier effect, despite being first noticed by Jean Peltier in 1834, remained a backwater of physics for over a century. However, in the last few decades, the technology has experienced a revival, leading to its incorporation into a number of commercial systems, our thermal desorption instrumentation being one.III. Peltier Effect (1834) The reverse of the Seebeck effect is also possible: by passing a current through two junctions, you can create a temperature difference. This process was discovered in 1834 by scientist named Peltier, and thus it is called the Peltier effect. This may sound similar to Joule heating described above, but in fact it is not.

Peltier Effect With Dissimilar Metals At the junction of two dissimilar metals the energy level of conducting electrons is forced to increase or decrease. A decrease in the energy level emits thermal energy, while an increase will absorb thermal energy from its surroundings. The temperature gradient for dissimilar metals is very small.
