Abstract

A wiring and power distribution device for a cabinet housing electronic equipment. The distribution device includes a plurality of compartments. Each compartment adapted to contain an electronic component, such as an uninterruptible power supply, a power-conditioning device, or a power distribution center containing circuit breakers. The distribution device also includes a cooling compartment, including a fan or passive convective chimney arranged to cool the interior of the cabinet with ambient air. The distribution device provides a single input point for power and signal wiring, and at least one output point for connection to the electronic devices contained within the cabinet.

Claims

1. A wiring distribution device for mounting to the top of an electronics cabinet or rack, comprising:

a housing having a top, a bottom and side walls;

a plurality of compartments formed in the housing for receiving electronic components, the compartments formed at discrete locations within the housing, at least one compartment including a cooling fan or passive convection cooling chimney designed to lower the temperature inside the cabinet, the cooling compartment including support walls mounted to the bottom of the housing about a hole formed in the bottom the walls configured to direct air past a fan mounted in the cooling compartment and toward an opening formed in the top;

a wiring input point;

a power distribution compartment mounted within one compartment adjacent to the wiring input point and on one side of the cooling compartment, the power distribution compartment mounted adjacent to an opening in the bottom for providing access to a power distribution component that is mounted within the compartment for supplying power to the cabinet;

a power control zone located adjacent to the power distribution compartment for mounting of one or more circuit breakers, the power control zone also located adjacent to one of the housing walls for providing access to the switches of the circuit breakers; and

a plurality of wiring output points for providing output of wires from the distribution device.

2. The device of claim 1, wherein the cooling compartment is located approximately in the center of the device, and wherein the cooling fan is arranged to draw ambient air from the interior of the cabinet and through the wiring distribution device.

3. The device of claim 1, wherein the housing includes at least one removable access panel so as to provide a user with access to the interior of the housing.

4. The device of claim 1, wherein the wiring input point is adapted to accept electrical power or signal interface wiring inputs for distribution to the electronic devices in the cabinet.

5. The device of claim 1, wherein the wiring output point is adapted to distribute electrical power or data signals to the electronic devices in the cabinet.

6. The device of claim 1, wherein at least one compartment includes a power-conditioning device for conditioning power supplied to the wire distribution device.

7. The device of claim 1, wherein at least one module is a power-supply device.

8. The device of claim 1, further comprising a monitoring module in the device including at least one display mounted to the housing and visible to a user from outside the housing, the display providing information indicative of the state of at least one component or the environment inside the cabinet.

9. The device of claim 8, wherein the display provides a visual indication of the temperature inside the rack or cabinet.

10. The device of claim 8, wherein the display provides graphical data or indicator lights depicting the status of the components in the cabinet or in the housing.

11. The device of claim 1, wherein at least one compartment channels audio wires into and out of the housing and another compartment contains a power supply, and wherein the compartment that channels the audio wires is located spaced as far apart from the compartment that contains the power supply as the housing permits so as to minimize interference.

12. The device of claim 1, wherein housing includes partitioning to separate class 1 and class 2 wiring for shielding the wires from electromagnetic interference.

13. A rack having an at least partially open top and electrical equipment contained within the rack, and a wiring distribution device according to claim 1 mounted to the top of the rack, the a power distribution component in the wiring distribution device electrically connected to the electrical equipment for supplying power to the equipment.

14. A wiring distribution device for mounting to the top of an electronics cabinet or rack, comprising:

a housing having a top, a bottom, side walls, and at least one removable access panel so as to provide a user with access to the interior of the housing;

a plurality of compartments formed in the housing for receiving electronic components, the compartments formed at discrete locations within the housing, at least one compartment including a cooling fan or passive convection cooling chimney designed to lower the temperature inside the cabinet, the cooling compartment including support walls mounted to the bottom of the housing about a hole formed in the bottom the walls configured to direct air past a fan mounted in the cooling compartment and toward an opening formed in the top, the cooling compartment being located approximately in the center of the device and arranged to draw ambient air from the interior of the cabinet and through the wiring distribution device;

a wiring input point;

a power distribution compartment mounted within one compartment adjacent to the wiring input point and on one side of the cooling compartment, the power distribution compartment mounted adjacent to an opening in the bottom for providing access to a power distribution component that is mounted within the compartment for supplying power to the cabinet;

a power control zone located adjacent to the power distribution compartment for mounting of one or more circuit breakers, the power control zone also located adjacent to one of the housing walls for providing access to the switches of the circuit breakers; and

a plurality of wiring output points for providing output of wires from the distribution device;

wherein at least one compartment includes a power-conditioning device for conditioning power supplied to the wire distribution device.
