Property evaluations of thermoelectric generator modules
By applying a maximum 500℃ 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.

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.
Applications
- Generation efficiency measurements of thermoelectric generator modules
- Lifespan testing of modules by thermal cycle testing
