Result description
During the Project INTEGRAL a test system for characterising TEGs was developed and built up. The task of this test rig, is to cycle TEGs, measure the performance to investigate reasons for performance losses. Single TE-modules up to 40 × 40 mm con be tested as at temperatures between 50 and approx. 950 °C for the hot side, while the cold side temperature can be adjusted between 20 and 80 °C by water cooling. Using oil for cooling, even temperatures above 100 °C can be applied to the cold side, so simulating of cooling systems of passenger cars or trucks is possible. In Combination with the above described microstructural analysis profound understanding of the physical and electrical interaction can be generated. In application oriented projects this knowledge will be used to develop more robust and reliable TEGs together with industrial partners like ISAB and research partners as DLR (Stuttgart, Germany), the Fraunhofer IPM (Freiburg, Germany) or Fraunhofer IFAM (Bremen and Dresden, Germany).
Addressing target audiences and expressing needs
- Collaboration
By tessting of TEGs followed by post test analysis with FESEM and EDS, degradation processes are detected. Combining the knowledge of materials science and thermophysics, more stable thermoelectric devices can be developed.
