Thermoelectrical Generators (SEEBECK Elements)

Thermoelectrical generators are constructed similar to peltier elements. In contrast to the PELTIER-effect, the SEEBECK-effect is used to get electrical energy on a direct way from a temperature difference within the element. (This is not the reversion of the PELTIER-effect. Both effects always work at the same time and cannot be observed apart from each other!). Since dimensioning a TEG is much more complex than the common use of a peltier element, please see the simple formulas and constants for the TEGs by Eureca.


The following tabular shows elements for a maximum operating temperature of up to 120 degree celcius. The indicated values are measured at a temperature difference of 100K.

TEG1-9.1-9.9-0.2/100 0.027 9.0 0.03 2.7 0.3 A 0.2 W 9.1 × 9.9 × 2.3 120
TEG1-30-30-2.1/100 0.054 3.4 0.3 5.4 1.6 A 2.1 W 30 × 30 × 3.6 120
TEG1-40-40-4.7/100 0.054 1.5 0.7 5.4 3.5 A 4.7 W 40 × 40 × 3.4 120

TEG1-40-40-10/100 0.082 1.7 1.6 8,2 4.9 A 10 W 40 × 40 × 3.2 120

The elements TEG1-40-40-4.7/100 and TEG2-40-40-4.7/100 provide almost identical technical data. The TEG2-40-40-4.7/100 is made in China and provides higher tolerances and a reduced life time, is however much cheaper.
