A weatherproof cabinet with multiple-compartment cooling includes a housing and
a door attached to the housing. The door includes a heat exchanger core, a first
duct located at least partially between the heat exchanger door and an exterior
of the door, and a second duct located at least partially between the heat exchanger
door and an electronics compartment. The door also includes an inlet vent and an
outlet vent that are pneumatically interconnected with the first duct. A fan is
located at least partially within the first duct and is operative to draw external
air into the first duct via the inlet vent, direct at least the first portion of
the external air across the heat exchanger core, and then direct the first portion
of the external air out of the first duct via the outlet vent. A partition is located
within the first duct and separates the inlet vent from the outlet vent so that
external air is not drawn into the first duct via the outlet vent during operation
of the fan.
