Things to Know About Thermoelectric Module
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.
The Biomedical industry, also gains profit from this device in DNA analyzers and various temperature stabilization equipment
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.
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. Â
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.
Ferrotec Nord has developed a huge range of thermoelectric module and each is built for different type of task.
Single stage- This is a type of thermoelectric module which can generate up to 73 degree Celsius differentiate between hot and cold sides.
Multistage TEM’S- This particular module offer a higher temperature than those single stage ones.
Micro TEM’S- This is a thermoelectric module downscaled for applications where small sixe matters.
Cycling TEM’S- This is used when a quick change of temperature is needed.
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.
