Solid-state cooling
GlossaryDefinition
Solid-state cooling is a method of heat transfer that uses semiconductor-based technologies to move heat using electrical current, without relying on mechanical components or refrigerants.
Context
Solid-state cooling is widely used in telecom, industrial, and energy applications where reliability, low maintenance, and sealed designs are essential. It is particularly relevant for outdoor enclosures exposed to dust, moisture, and vibration, where traditional compressor-based systems may be less effective. Vikinor applies solid-state cooling in solutions requiring stable performance in harsh environments and minimal service requirements.
Technical insight
Solid-state cooling is primarily based on the Peltier effect, which enables heat transfer through semiconductor materials when powered by electrical current.
Key principles and components:
Thermoelectric modules (TEC)
The most common implementation of solid-state cooling, using semiconductor junctions to create a temperature difference.
Heat transfer mechanism
- Cold side: absorbs heat from the enclosure
- Hot side: dissipates heat to the external environment
Direct current operation
Systems typically operate on DC power, making them suitable for telecom and off-grid applications.
No mechanical components
Eliminates compressors, fans (in some designs), and refrigerants, reducing failure points.
Thermal management requirements
- Efficient heat dissipation is critical for performance
- Requires proper heat sinks or external airflow
- System design directly impacts cooling capacity
System-level relevance
Solid-state cooling is used in thermoelectric cooling systems where reliability and environmental sealing are prioritized over high cooling capacity.

FAQ
Solid-state cooling uses semiconductor technology with no moving parts, while compressor systems rely on refrigerants and mechanical components.
It is commonly used in sealed enclosures and environments where reliability and low maintenance are critical.
It is efficient for small to moderate cooling loads and precise temperature control, but less suitable for high-capacity cooling compared to compressor systems.
