Importantly, our technology is applicable for both cooling and heating components in automobiles. Needless to say, we back up our technology with Ferrotec's global network of technical support." 

Ferrotec thermoelectric modules 

Ferrotec is the world's largest manufacturer of bismuth telluride (Bi-Te) thermoelectric modules (TEM) (Peltier Effect devices). To-date the company's TEM have mainly been used for cooling chillers, optical communications, biotechnology, air conditioners, as well as a wide range of consumer electronics.

Now, starting in Fall 2018, the company will focus on applications of Ferrotec-thermoelectric modules in the automobile industry, in particular for electric and hybrid cars.

Specific applications include: 

  • Cooling laser diodes in head up displays in automobiles
  • Cooling batteries of electric and hybrid cars
  • Cool cup holders in car cabins
  • Cooling laser devices in LIDAR technology in autonomous vehicles
  • Cooling laser diodes in laser head lights

Features of Ferrotec thermoelectric modules and technology 

Ferrotec thermoelectric modules are highly responsive and offer control to less than 0.1 degree Celsius. Furthermore, Ferrotec offers customized solutions for clients by designing unique thermoelectric modules for specific applications.

New heating applications of thermoelectric modules for electric cars in cold climates 

Ferrotec thermoelectric modules are suitable for heating batteries in electric cars to overcome the poor performance of batteries in cold weather conditions.

Peltier devices

Thermoelectric modules consist of plate like semiconductor Peltier effect devices where the passage of electric currents between two different metals sandwiching bismuth telluride semiconductor plates moves heat between the two junctions.
