The Mini-PEM can be used to calculate the thermoelectric conversion efficiency for a single thermoelectric material and a pair of thermoelectric materials.
This system has the ability to assess the thermoelectric module's conversion efficiency and power generation. A heat flow meter is used to measure heat flow, and the four-probe method assesses the current dependence of power generation; from these, the conversion efficiency is calculated.
The low-temperature half is cooled by water flow, while the high-temperature segment can reach up to 500 °C (standard specifications).
Applications
- Power generation and heat flow are used to compute the module conversion efficiency
- Evaluation of heat flow and power generation only using thermoelectric materials
- Thermoelectric module performance and lifetime evaluation
Features
- Able to assess the output characteristics of a small module that measures 2 to 10 mm (square) and 1 to 20 mm (height)
- Measures power generation and heat flow data before calculating conversion efficiency
- The high-temperature component can reach up to 500 °C
- Easy operation with control software
