First Claim
1. An outdoor equipment cabinet comprising:
- a housing;
a first opening in a first sidewall of said housing;
a first door attached to said housing having a first position providing access to said first opening and a second position closing access to said first opening;
an equipment compartment within said housing and being accessible via said first opening;
an intake air vent formed in said housing;
an exit air vent formed in said housing;
a fan mounted within said housing for pulling air into said intake air vent, moving an air stream through said equipment compartment, and pushing air out of said exit air vent;
a membrane disposed adjacent said intake air vent, wherein said membrane allows air to pass therethrough but resists the passage of water and contaminants therethrough; and
at least one baffling plate disposed in said equipment compartment for changing a path of the air stream to direct the air stream toward a particular electronic component disposed within said equipment compartment, wherein said at least one baffling plate includes a first baffling plate with an adjustable mount so that an angle of said first baffling plate may be adjusted by a user to redirect the air stream.

Abstract
An outdoor equipment cabinet includes a housing with an equipment compartment therein. An intake air vent and an exit air vent are formed in the housing. A fan is mounted within the housing for pulling air into the intake air vent, moving an air stream through the equipment compartment, and pushing air out of the exit air vent. A membrane is disposed adjacent the intake air vent. The membrane allows air to pass therethrough, but resists the passage of water and contaminants therethrough. In some embodiments, a baffling plate is disposed to direct the air stream within the equipment compartment, and/or the fan speed is controlled by a temperature sensor, and/or a clogging of the membrane is monitored and reported, and/or the intake air vent is located in a first door and the exit air vent is located in a second door of the cabinet.
