Thermoelectric Module Basics
Thermoelectric cooling module is a semiconductor device, that
converts electrical energy into cooling power. Thermoelectric
module operates on the principle of the heat pump, wherein one side
is cooled and the other - heated.
By applying a low voltage DC power to a TE module, heat will be
moved through the module from one side to the other. One module
face, therefore, will be cooled while the opposite face is
simultaneously heated. It is important to note that this phenomenon
may be reversed whereby a change in the polarity (plus and minus)
of the applied DC voltage will cause heat to be moved in the
opposite direction. Consequently, a thermoelectric module may be
used for both heating and cooling thereby making it highly suitable
for precise temperature control applications. A thermoelectric
module can also be used for power generation. In this mode, a
temperature differential applied across the module will generate a
A practical thermoelectric module generally consists of two or more
elements of n and p-type doped semiconductor material that are
connected electrically in series and thermally in parallel. These
thermoelectric elements and their electrical interconnects
typically are mounted between two ceramic substrates. The
substrates hold the overall structure together mechanically and
electrically insulate the individual elements from one another and
from external mounting surfaces.
Cooling capacity (heat actively pumped through the thermoelectric
module) is proportional to the magnitude of the applied DC electric
current and the thermal conditions on each side of the module. By
varying the input current from zero to maximum, it is possible to
regulate the heat flow and control the surface temperature.
