THERMOELECTRIC GENERATORS

In 1821 the German physicist Thomas Johann Seebeck discovered that when two strips of different electrically conducting materials were separated along their length but joined together by two “legs” at their ends, a magnetic field developed around the legs, provided that a temperature difference existed between the two junctions. He published his observations the following year, and the phenomenon came to be known as the Seebeck effect.

Thermoelectric generators are all solid-state devices that convert heat into electricity. Unlike traditional dynamic heat engines, thermoelectric generators contain no moving parts and are completely silent. A thermoelectric device is a solid-state, semiconductor-based electronic component capable of converting a voltage input into a temperature difference which can be used for either heating or cooling. Conversely, when a temperature difference is applied to the device, it has capability of producing DC electrical power.

Thermoelectric Modes:

1. Cooling

2. Heating

3. Power Generation

WHAT IS THERMOELECTRIC REFRIGERATION/ COOLING?

Refrigeration is the process of pumping heat energy out of an insulated chamber in order to reduce the temperature of the chamber below that of the surrounding air. Thermoelectric refrigeration uses a principle called the "PELTIER" effect to pump heat electronically. The Peltier effect is named after a French scientist who discovered it in 1834.
