Thermoelectric Evaluation System
Atmospheric Thermoelectric Module Evaluation System
F-PEM
アルバック販売
The system can evaluate the power generation and heat flow that can be gathered when the temperature difference is given to thermoelectric module in the environment(in atmosphere and under load) and conversion efficiency that can be calculated from maximum power generation and heat flow. In addition, this system can conduct long-hours operation and heat cycle tests of thermoelectric modules and can be used for testing newly developed modules as well as for durability tests under load and temerature in which commercially available modules are actually incorporated.
Features
- The output of characteristics of the module can be evaluated by continuous loading at a high temperature in air.
- Repeated measurement of Pmax is possible at constant intervals while continuing to apply load for a long time.
- Measurement can be performed while applying a constant load in accordance with the actual module built-in environment.
Applications
- Evaluation of maximum power generation and heat flow of thermoelectric modules in air and under load
- Evaluation of conversion efficiency of module calculated from maximum power generation and heat flow
- Evaluation of durability of thermoelectric modules by long-hours measurement
