How much electrical power does this thermoelectric module generate and for how long? At what temperatures does it work best? What is the influence of the contact pressure and what happens when you operate the thermoelectric module in air?
We provide answers to these and other questions about your Peltier elements and thermoelectric modules.
At our measuring stations, we precisely characterize thermoelectric modules (TEM) with regard to efficiency, long-term stability and thermoelectric properties. Our investigations provide a comprehensive understanding of the quality and optimal operational conditions required for your modules. Among others, we offer the following investigations:
- Cycling tests at hot side temperatures of up to 500°C
- Failure analyses - e.g. by observing the degradation of solder joints and material fatigue when exposed to air during long-term tests
- Measurement of the heat powers transported by the TEM and electrical powers generated, also as part of long-term tests
In addition to thermal and electrical measurements, we are able to examine TEM in a 3D computer tomograph, in a scanning electron microscope (SEM) or by means of energy dispersive X-ray spectroscopy (EDX) for material changes and internal damage. This makes it possible to create comprehensive analytical chains that are specifically tailored to individual requirements.
