THERMOELECTRIC MODULES
Reliable temperature control using advanced Peltier technology for demanding electronic and industrial applications. Thermoelectric modules move heat using electrical energy, making it possible to create compact cooling systems without moving parts or refrigerants. This results in solutions that are reliable, low maintenance, and built for long-term operation. The technology provides precise temperature control and is particularly well suited for applications where conventional compressor-based cooling systems are too large, too complex, or simply not practical.

What is Thermoelectric Cooling?
Thermoelectric cooling is a solid-state technology that generates a temperature difference between the upper and lower ceramic when electrical current flows through a thermoelectric module.
When direct current passes through the semiconductor elements inside the module, heat is actively transported from the upper side of the device to the other.
As a result:
• one surface of the module becomes cold
• the opposite surface becomes hot
The heat absorbed on the cold side must then be dissipated on the hot side using a heat sink or other thermal management systems.
This phenomenon is known as the Peltier Effect, discovered in 1834 by the French physicist Jean Charles Athanase Peltier.
How a Peltier Module works
A thermoelectric module consists of multiple semiconductor couples that are electrically connected in series and thermally connected in parallel.
When electrical current flows through these semiconductor elements, heat energy is transported through the module from the cold side to the hot side.
By controlling the electrical current supplied to the module, the cooling capacity and temperature difference can be precisely regulated.
Thermoelectric systems therefore allow highly accurate temperature stabilization, even in applications requiring very small or localized cooling areas.
Structure of a Thermoelectric Module
A typical thermoelectric module consists of two ceramic plates that provide mechanical stability and electrical insulation. Between these ceramic layers, multiple P-type and N-type semiconductor elements are arranged to form thermoelectric couples.
The main components include:
Ceramic Plates
Provide electrical insulation while allowing efficient heat transfer between the module and the surrounding system.
P-Type Semiconductor Elements
Carry positive charge carriers and contribute to the thermoelectric effect.
N-Type Semiconductor Elements
Carry negative charge carriers and work together with the P-type elements to create the temperature gradient.
Copper Interconnects
Provide the electrical path that allows current to flow through the semiconductor couples.
Together, these elements form a compact solid-state device capable of transferring heat with high precision.
Advantages of Thermoelectric Cooling
Thermoelectric cooling offers several advantages compared to conventional cooling technologies.
• No moving parts – extremely reliable and low maintenance
• Silent operation – no compressors or mechanical components
• Compact design – ideal for integration into systems with space constraints
• Precise temperature control – accurate regulation of sensitive components
• Environmentally friendly – no refrigerants required
• High reliability – long operational lifetime
These characteristics make thermoelectric modules particularly suitable for applications requiring stable, localized and maintenance-free cooling.
