Thermoelectric Converter
Product Code : JLI-PLE-11265
Quick Answer: The Thermoelectric Converter is a demonstrator made of semiconducting junction plates sandwiched between 2 aluminium heat-conducting plates. Driven at 5V DC it creates a temperature difference, and a temperature difference across it generates current that turns a small fan.

Key Features
- Semiconducting junction plates sandwiched between 2 aluminium heat-conducting plates.
- Selector switch connects the junction plates either to the motor fan or to a pair of 4mm sockets.
- With the sockets selected and a 5V DC supply applied, a temperature difference builds up across the aluminium plates.
- A temperature difference between the two sides generates a current that drives the little fan, so the output can be seen.
Technical Specifications
| Specification | Value |
|---|---|
| Junction element | Semiconducting junction plates |
| Heat-conducting plates | 2 x aluminium |
| Terminals | Pair of 4mm sockets |
| Drive voltage (sockets selected) | 5V DC |
| Output indicator | Small motor-driven fan |
| Mode selector | Switch: fan or 4mm sockets |
How It Is Used
With the switch set to the 4mm sockets and 5V DC applied, the junction plates set up a temperature difference that the aluminium plates conduct to either side. With the switch set to the fan and the two sides held at different temperatures, the junction generates a current and the fan turns, showing heat energy being converted into electricity.
Frequently Asked Questions
How is the Thermoelectric Converter switched between its two modes?
A switch on the unit connects the junction plates either to the motor fan or to a pair of 4mm sockets. With the sockets selected and driven at 5V DC, a temperature difference is created across the aluminium plates.
How does the Thermoelectric Converter show that a current is produced?
When a temperature difference exists between the two sides of the junction plate, electric current is generated and drives a little fan, giving a visual demonstration of the current.
