Thermoelectric module
or commonly known as TEM, is a device which works on the basis of Peltier
effect, that allows turning heat into electricity or vice versa. Silent
operation, solid design, absence of moving parts and vibrations as well as
removal of hazardous materials like any gas or fluid are some of the advantages
of this particular device.

In the telecom industry, this particular product
is used to provide cooling for transition lasers, photo –diodes, as well as to
stabilize the temperature of optical channel. Over the last few years this has
become one of the essential machines in the industry.
- Ø
The Biomedical industry, also gains profit from
this device in DNA analyzers and various
temperature stabilization equipment
- Ø
The Automotive industry also uses this thermoelectric module, for in-cabin
refrigerators, climate seats in which there is some uniform heating and cooling
with optimized air distribution and also for air conditioning and electric
power generation.
- Ø
Not only in the arena of industrial sector, but
thermoelectric module is also used in various consumer products like picnic
boxes, water chillers and many more.

TM can also provide spot cooling or heating.
Recently there is a huge demand for spot cooling. The demand for Spot Air
conditioners are increasing in the market.
Any thermoelectric module works on the basis of Peltier
effect. When, electric power goes through a contact of two different current-
conducting materials, one gets hotter and the other gets cool. This is the way
how thermoelectric module works.
This particular effect can also have a reversal role for generating electricity
when the hot part of the thermoelectric module receives a heat flux. As said
earlier, thermoelectric module can act both as a cooling or heating element
when precise temperature calibration is needed for various technological
purposes.
Types of TEM
Ferrotec Nord has developed a huge range of thermoelectric module and each is built
for different type of task.
- Ø
Single stage- This is a type of thermoelectric module which can
generate up to 73 degree Celsius differentiate between
hot and cold sides.
- Ø
Multistage TEM’S- This particular module offer
a higher temperature than those single stage ones.
- Ø
Micro TEM’S- This is a thermoelectric module downscaled for applications where small sixe
matters.
- Ø
Cycling TEM’S- This is used when a quick
change of temperature is needed.
- Ø
Generating TEM’S- This is used to generate
electricity from the heat supplied to it.
There are certain ways over choosing of a thermoelectric module.
Commonly in most of the application, the thermoelectric module ensures the difference between the ambient
temperature and the cooled object temperature through the heat removal from the
object to the heat sink.
While choosing a module, it should be remembered that, full
thermal load Qc comprises the capacity needed to cool the object and various
other types of heat, which inflows from outside owing to heat emission and heat
conductivity of the elements installed in the device.
This is the only device which performs various
activities from a single unit system, both in the industry and in the consumer
forum.
