Mini-PEM: Thermoelectric Conversion Efficiency Evaluation System for Small Modules

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
