Systems and methods for weatherproof cabinets with multiple compartment cooling
View Patent ↗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.
1. A weatherproof cabinet with multiple-compartment cooling, comprising:
a housing;
an electronics compartment located with the housing and being configured for storing electronics;
a first fan located within the housing and operative to re-circulate internal air within the electronics compartment;
a battery compartment located with the housing and being configured for storing a battery;
a door attached to the housing and being movable to provide selective access to the electronics compartment and the battery compartment, the door comprising:
a heat exchanger core;
a first duct located, at least partially, between the heat exchanger core and an exterior of the door;
a second duct located, at least partially, between the heat exchanger core and the electronics compartment;
an inlet vent pneumatically interconnected with the first duct;
an outlet vent pneumatically interconnected with the first duct;
a second fan located, at least partially, within the first duct; and
a partition located within the first duct and separating the inlet vent from the outlet vent such that external air is not drawn into the first duct via the outlet vent during operation of the second fan;
the second fan being operative to draw external air into the first duct via the inlet vent, direct at least a 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;
an opening located directly between the battery compartment and the first duct; and
a battery compartment vent operative to discharge air from the battery compartment such that at least a second portion of the external air drawn into the first duct is directed through the opening and is discharged from the housing via the battery compartment vent.
2. The weatherproof cabinet of claim 1 , wherein said door provides a front wall to said housing including said electronics compartment and said battery compartment.
3. The weatherproof cabinet of claim 1 , wherein said door provides a front wall to said electronics compartment, and further comprising a lower panel to provide a front wall for said battery compartment, wherein said battery compartment includes the opening.
4. The weatherproof cabinet of claim 3 , wherein said opening of said external duct and said opening of said battery compartment are connected by a flexible tubing for the through-flow of air between said external duct and said battery compartment.
5. The weatherproof cabinet of claim 1 , further comprising at least one internal wall disposed within said electronics compartment, wherein said internal wall directs the circulation of the internal air within said electronics compartment.
6. The weatherproof cabinet of claim 1 , further comprising a cable entrance compartment disposed within said housing, wherein said cable entrance compartment includes at least one additional opening for the routing of cables into said cabinet.
