Active Cooling of Outdoor Enclosure Under Solar Loading

摘要

An outdoor enclosure for electronic equipment is described. A shroud mounted around the enclosure provides a plenum for external air, as well as protection from solar loading. A fan located inside the equipment enclosure circulates the air inside the equipment enclosure downward along the sides of the enclosure to accomplish heat exchange with external air. Another fan draws external air upwardly across the surfaces of the equipment enclosure. The heated external air is exhausted at the top of the shroud.
