Power Generation Efficiency Characteristics Evaluation System PEM-2

Property evaluations of thermoelectric generator modules

By applying a maximum 500°C temperature difference across a thermoelectric generator module, this system finds the thermoelectric conversion rate η by finding the power that is generated P when a one-dimensional heat flow Q is passed through the module.

Applications

  • Generation efficiency measurements of thermoelectric generator modules
  • Lifespan testing of modules by thermal cycle testing

Features

  • Uses an Infrared Gold Image Furnace with excellent temperature controllability to allow rapid module performance evaluations and endurance testing.
  • Capable of applying a maximum 500°C temperature difference across the top and bottom surface of the module.
  • Capable of measuring the amount of heat passed through the module.
  • Stably maintains the thermal resistance of the contact surface during heating with the air cylinder mechanism.
  • Measurement behavior can be configured with only software settings by temperature stability judgments, automatic variation of the load on the thermoelectric generator module, and automatic control of the measurement temperature.
