What exactly is Thermoelectric Cooling and Why Do We Use It?

What’s Thermoelectric Cooling?

Thermoelectric cooler modules are solid state heat pumps that operate based on the Peltier impact. Get more details about сервопривод на коллектор

When an electrical existing is supplied, the devices are capable of cooling or heating and can be thermally cycled at PWM (pulse width modulator) frequencies.

Alternatively, they might be used to lessen the effects of temperature coefficients on oscillator stability, reference voltages and amplifier offsets by giving temperature control.

Why use Thermoelectrics?

Thermoelectric cooler modules are best for applications that need active cooling under ambient temperatures. A design engineer should really take into account thermoelectric cooling when a system design calls for localised electronic cooling with

Precise Temperature Control

Peltier coolers have fast feedback control mechanisms with temperature control to inside fractions of a degree.

Higher Reliability

Strong state technology suggests that modules have MTBF (imply time among failure) of more than 100,000 hours.

Suitability for Hazardous, Extreme or Remote environments

Thermoelectric modules have no moving parts and demand practically no maintenance. They are also capable of cooling far below ambient temperature.

Compact Physical Constraints

Compact geometry constraints and low weight.


Solid state cooling indicates no need to have for chemical coolants, with no CFC or refrigerant emissions.

No refilling is required.


The thermoelectric impact is modular and scalable. In general cooling power is proportional to location and volume.


Thermoelectrics may be used to heat and cool by basically reversing the existing. Thermoelectric generators (TEGs) are also used to harvest energy from waste heat. These can then be constructed in to the system to supply electricity to localised cooling/heating systems.

Thermoelectric Assemblies

Adaptive® thermoelectric assemblies consist of several thermal management elements. Fans, heatsinks/ heatpipes and thermal interface products are used in combination with TEMs to optimise cooling or heating efficiency.

There are two sorts of thermoelectric assemblies that we supply by way of distributors (see image under).

Direct-to-air systems are where solid surfaces are cooled and heat is dissipated towards the surrounding air.

Air-to-air systems are where the air in an enclosure is cooled and the heat is dissipated for the surrounding air (commonly using two fans).
