- Open Cabinets with Natural Convection: Require clean environments, offering medium heat dissipation.
- Open Cabinets with Forced Ventilation: High heat dissipation capability, requiring airflow calculations.
- Closed Cabinets with Forced Ventilation and Heat Exchanger: Suitable for high power dissipation in harsh environments.
- Air Conditioned Cabinets: Ideal for hot climates, maintaining cabinet temperature at or below ambient levels.
Installation Recommendations
For optimal performance, install isolators with consideration for heat dissipation and airflow. Horizontal installation improves heat transport, and units with higher power dissipation should be placed at the top of the cabinet. Maintain a minimum distance of 5 cm between isolators and cable ducts to ensure proper ventilation.
