- Cold face can form ice under suitable conditions, strong visual for classroom thermoelectric lessons.
- Description
Description
The thermo-generator is a thermoelectric cell that operates using the Peltier effect. Unlike a thermocouple, which generates a small voltage when a junction of two different metals is heated, this unit produces a temperature difference when DC current is driven through many junctions formed into a flat plate. One face becomes hot and the opposite face becomes cold, making the heating and cooling effect easy to observe in real time.
In the IEC thermo-generator, two 4 mm sockets allow DC to be applied using standard lab leads. The hot and cold sides are very obvious during operation, and under suitable conditions the cold side can drop low enough for ice to form, providing a strong visual demonstration for thermoelectric lessons.
FAQs
Q: What effect does this unit demonstrate?
A: The Peltier effect, heating on one side and cooling on the other when DC current is applied.
Q: How is it powered?
A: By applying DC through the two 4 mm sockets.
Q: What will I observe during operation?
A: One side becomes hot and the other side becomes cold, with a clear temperature difference.
Q: Can ice form on the cold side?
A: Yes, ice can form on the cold side under suitable conditions.
Q: What are the terminals for connection?
A: Two 4 mm sockets for standard laboratory leads.
