Thermoelectric Effect Demonstrator

What is the thermoelectric effect?

The thermoelectric effect is the direct conversion of temperature differences to electric voltage and vice-versa. A thermoelectric device creates voltage when there is a different temperature on each side. Conversely, when a voltage is applied to it, it creates a temperature difference. At the atomic scale, an applied temperature gradient causes charge carriers in the material to diffuse from the hot side to the cold side.

This effect can be used to generate electricity, measure temperature or change the temperature of objects. Because the direction of heating and cooling is determined by the polarity of the applied voltage, thermoelectric devices can be used as temperature controllers.

In other words, if there isn't a sufficient temperature differential, you will not generate power. We noticed in our test that the propeller started to work when the cold water was at 16º Celsius and the hot water at 66º Celsius. We took the temperature again when it stopped and noticed that the cold water warmed up a little to 27º Celsius and the hot water cooled down to 40º Celsius.

Thermoelectric Cooler

Thermoelectric Cooler has two sides. When connected to a battery or any other source of direct current, one side becomes ice cold and the other side gets hot. You can switch the hot and cold surfaces by simply reversing the polarity, used for numerous applications from CPU coolers to alternate power sources, or even for your own custom car drink cooler/ refrigerator.

Operation voltage: 0~15.2V DC 
Operation current: 0~6A 
Operation Temperature: -30°C to 70°C 
Max power consumption: 60 Watts 
Size: 40mm x 40mm x 4mm 

These devices must be used in conjunction with a heat sink to avoid burning. Each device is fully inspected and tested.

Fitted with 6-inch insulated leads.
