In the recent years, we
all are facing electricity crisis. It’s time to harness the renewable energy
resources of the nature.
The TEM operating principle is based on the
Peltier effect. The Peltier effect is a temperature difference created by
applying a voltage between two electrodes connected to a sample of
semiconductor material. One of the TEM sides is cooling and the other side is
heating. When a TE module is used, you must support heat rejection from its hot
side. If the temperature on the hot side is like the ambient temperature, then
we can get the temperature on the cold side that is lower (tens of Kelvin
degrees). The degree of the cooling is depended from the current value that is
leaking through a thermoelectric module. In a thermo-electric heat exchanger
the electrons acts as the heat carrier. The heat pumping action is therefore
function of the quantity of electrons crossing over the p-n junction.
