A guide to protecting electrical enclosures

03May

Inside an electrical enclosure, every 10°C rise in temperature reduces the reliability of the electronic components by 50 percent. As technology advances, electronics get smaller, leading to more electronic components inside a single electrical enclosure.

These tightly packed components help conserve space and allow for more efficient automation, but leave very little room for heat dissipation and airflow circulation. This contributes to higher internal enclosure temperatures, which can ultimately lead to electronic overheating, control failures, and system shutdowns. To combat system failure, cabinets must be equipped with an enclosure cooling system, such as passive cooling types (fans, blowers, heat sinks, and heat exchangers), and active types (air conditioners, thermoelectric devices, and vortex coolers).
