How can you stop an outdoor enclosure from overheating in summer?
Short answer
To stop an outdoor enclosure overheating, fit adequate ventilation. As the air inside heats it expands, and the resulting pressure can damage components and reduce the enclosure's protection; vents equalise natural heating and cooling without affecting protection levels. Ventilation also releases the heat generated by the components themselves and stops trapped moisture condensing inside. The vents must allow airflow without letting hazards such as dust in, so choose a rated element: our ventilation range includes IP44 and IP65 options, designed for vertical installation in enclosure walls.
While enclosures are designed to cope with some temperature fluctuation, there are steps you can take to make sure yours does not get too hot at any time of year. Adequate ventilation is the most important of them, because it stops enclosures from overheating and allows a build-up of moisture or pressure to escape.
Enclosures protect electrical components from external hazards such as dust and water, but when the air inside expands as it heats, pressure can increase, leading to damage and reduced protection. Vents allow that pressure to escape, equalising natural heating and cooling without affecting protection levels.
Even when an enclosure is not exposed to changes in ambient temperature, the components inside can generate heat. Releasing that build-up is important both to maintain safe operating conditions and to avoid the condensation of trapped moisture. Good air circulation reduces humidity inside the enclosure, but the vents must enable flow without letting potential hazards such as dust in.
