What are Peltier elements

Peltier elements are electrothermal converters and are used for cooling or heating, mainly in the technical field. Peltier elements are also known as TEC (Thermoelectric cooler).

Structure of Peltier elements

Peltier elements consist of two ceramic plates arranged parallel to one another, between which a large number of so-called Peltier pellets are arranged. These pellets consist of a semiconductor material based on quite exotic materials such as indium, bismuth, tellurium and the like. At the contact points of these pellets with one another, the Peltier effect results in a temperature difference when a current flows. This causes one of the outer ceramic plates to cool down while the other heats up.

Areas of application of Peltier elements

Peltier elements are used wherever wear-free cooling is required and no coolant is used. Peltier elements therefore do not use any moving parts. The cooling temperature depends on the ambient temperature.

The areas of application for Peltier elements include:

• Temperature control of samples, for example in the thermal cyclers used in molecular biology (PCR machines, also known as PCR blocks) for the replication of genetic material (DNA / RNA) [PCR: Polymerase Chain Reaction]
• Cooling of electronic components such as
  • CCDs
  • Infrared sensors
  • MEMS components (MEMS: microelectromechanical system / microsystem)
  • Laser diodes
  • Photodiodes
  • CPUs
• Peltier elements in cool boxes where only little space is available
• Dehumidifier
• Construction of climatic chambers

Durability & service life of Peltier elements

In contrast to other cooling modules, Peltier elements have an above-average service life and – depending on processing, intended use and environment – can function for over 20 years.

The service life of Petier elements is increased by:

• Compliance with the temperature specifications
• Use of Peltier elements, which are selected for the purpose
• High quality manufacturing
• Sealing

Advantages of Peltier elements

• Very long service life
• Very small size
• Low wear (no moving mechanical components)
• Adjustable cooling / heating output

Disadvantages of Peltier elements

• High power consumption / low efficiency, especially with multi-stage Peltier elements
• Use only for smaller applications
