Abstract
A fluid protection cover for an electronic device includes a cowl configured to fit at least partially over an electronic device enclosure and shield a convection vent opening in the electronic device enclosure against fluid ingress, an opening located underneath the cowl and configured to permit the passage of air from an interior region of the electronic device enclosure to the ambient air, and a primary louver located underneath the cowl. The primary louver includes an inclined surface configured to direct fluid away from the opening. The fluid protection cover further includes a first end cap and a second end cap. Each end cap is configured to fit at least partially over an exterior face of the electronic device enclosure and join the cowl to the primary louver.
