What is Thermoelectric Cooling and Why Do We Use It?

What exactly is Thermoelectric Cooling?

Thermoelectric cooler modules are strong state heat pumps that operate based on the Peltier effect. Get a lot more information regarding сервопривод oventrop

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

Alternatively, they may be used to decrease the effects of temperature coefficients on oscillator stability, reference voltages and amplifier offsets by offering temperature control.

Why use Thermoelectrics?

Thermoelectric cooler modules are perfect for applications that demand active cooling under ambient temperatures. A design engineer really should consider thermoelectric cooling when a system design needs localised electronic cooling with

Precise Temperature Control

Peltier coolers have rapidly feedback control mechanisms with temperature control to within fractions of a degree.

Higher Reliability

Strong state technologies suggests that modules have MTBF (mean time amongst failure) of extra than one hundred,000 hours.

Suitability for Hazardous, Extreme or Remote environments

Thermoelectric modules have no moving parts and need virtually no upkeep. They’re also capable of cooling far below ambient temperature.

Compact Physical Constraints

Compact geometry constraints and low weight.


Strong state cooling signifies no require for chemical coolants, with no CFC or refrigerant emissions.

No refilling is necessary.


The thermoelectric effect is modular and scalable. Generally cooling power is proportional to region and volume.


Thermoelectrics is usually used to heat and cool by merely reversing the current. Thermoelectric generators (TEGs) are also used to harvest energy from waste heat. These can then be constructed into the system to provide electricity to localised cooling/heating systems.

Thermoelectric Assemblies

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

You will find two kinds of thermoelectric assemblies that we supply through distributors (see image under).

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

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