Peltier Cold Plate Cooler Thermoelectric Cooling Plate Conditioner
•Three separate theories behind the operation of thermoelectric
cooling first appeared in the 1800s.
•Seebeck effect: Alessandro Volta and Thomas Johann Seebeck (1821)
found that holding the junctions of two dissimilar conductors at
different temperatures creates an electromotive force or voltage.
This is the basis for thermocouples.
•Peltier effect: Jean-Charles Peltier discovered (1834) a
heating/cooling effect when passing electric current through the
junction of two conductors.
•Thomson effect: William Thomson (Lord Kelvin) showed (1851) that
over a temperature gradient, a single conductor with current
flowing in it has reversible heating and cooling.
