Abstract

A filter assembly comprising a cover plate and a filter support. The filter support includes a length extending perpendicularly from an edge of the cover plate, a first edge and a second edge defining a height, a first U-shaped filter support extending from the first edge and a second U-shaped filter support extending from the second edge. The first U-shaped filter support and the second U-shaped filter support are configured to hold a filter there-between.

Claims

1. A filter assembly comprising:

a cover plate; and

a filter support, the filter support having;

a length extending perpendicularly from an edge of the cover plate;

a first edge and a second edge defining a height;

a first U-shaped filter support extending from the first edge; and

a second U-shaped filter support extending from the second edge, wherein the first U-shaped filter support and the second U-shaped filter support are configured to hold a filter there-between.

2. The filter assembly of claim 1, wherein the cover plate comprises:

at least one hole, each hole configured to accept a screw, wherein each screw is operable to attach the cover plate to an equipment chassis when the filter support is positioned in a filter-assembly slot within the equipment chassis.

3. The filter assembly of claim 1, the filter support having at least one opening positioned between the first and the second edges to permit air flow through a filter held by the first U-shaped filter support and the second U-shaped filter support.

4. A telecommunications equipment system comprising:

a chassis to house telecommunications equipment;

a filter assembly having a filter support, the filter support configured to fit within the chassis in the path of an airflow; and

a filter configured to fit within the filter support extending the majority the length of the chassis, wherein air in the path of the airflow is filtered by the filter.

5. The telecommunications equipment system of claim 4, further comprising:

a partially opened exterior surface of the chassis;

a fan system within the chassis to generate the airflow between the partially opened exterior surface and at least one fan in the fan system; and

a filter-assembly slot between at least one opening in the partially opened exterior surface and the fan, wherein the filter support is configured to fit within the chassis in the filter-assembly slot.

6. The telecommunications equipment system of claim 5, the filter assembly further comprising:

a cover plate, wherein the filter support has a length extending perpendicularly from the cover plate.

7. The telecommunications equipment system of claim 6, wherein the cover plate further comprises:

at least one hole, each hole configured to accept a screw, wherein each screw is operable to attach the cover plate to the chassis when the filter support is positioned in the filter-assembly slot.

8. The telecommunications equipment system of claim 5, wherein the filter support comprises:

a first edge and a second edge defining a height;

a first U-shaped filter support extending from the first edge; and

a second U-shaped filter support extending from the second edge, wherein the first U-shaped filter support and the second U-shaped filter support are configured to hold the filter there-between; and

at least one opening between the first edge and the second edge to permit air flow through the filter held by the first U-shaped filter support and the second U-shaped filter support.

9. The telecommunications equipment system of claim 8, wherein, when the filter assembly is positioned within the chassis, the at least one opening between the first edge and the second edge and the partially opened exterior surface of the chassis are both within the path of the airflow.

10. The telecommunications equipment system of claim 9, wherein an area of the at least one opening between the first edge and the second edge is about equal to an area of the partially opened exterior surface of the chassis.

11. The telecommunications equipment system of claim 4, wherein the telecommunications equipment is operable when the filter support is positioned within the chassis, positioned partially within the chassis, and removed from the chassis.

12. A method of manufacturing a filter assembly, the method comprising:

forming a cover plate; and

forming a filter support connected to and extending perpendicularly from a face of the cover plate, the filter assembly including a first U-shaped filter support and a second U-shaped filter support.

13. The method of claim 12, wherein forming the cover plate comprises:

shaping a metal sheet into a first section; and

forming two screw holes in the first section.

14. The method of claim 13, wherein forming the filter support comprises:

forming a metal sheet into a second section having a first edge and a second edge defining a height;

forming a first U-shaped filter support extending from the first edge;

forming a second U-shaped filter support extending from the second edge; and

forming at least one air-pass-through opening in the second section between the first edge and the second edge.

15. The method of claim 14, further comprising:

attaching the filter support to the cover plate, wherein the first U-shaped filter support and the second U-shaped filter support are perpendicular to the cover plate, and wherein the U-shapes in the first U-shaped filter support and the second U-shaped filter support open towards each other.

16. The method of claim 12, wherein forming the cover plate comprises:

shaping a metal sheet into a first section and a second section, wherein the first section and a second section share a boundary;

forming at least one screw hole in the first section, and wherein forming a filter support comprises;

forming openings in the second section, the openings having a height less than a height of the first section; and

bending the first section with respect to the second section along the boundary until the first section is perpendicular to the second section

17. The method of claim 16, wherein forming the cover plate further comprises:

removing a portion of the metal sheet at a boundary between the first section and the second section.

18. The method of claim 16, wherein the second section has a first edge and a second edge, the second edge parallel to the first edge and perpendicular to the boundary, and wherein forming the filter support further comprises:

shaping the first edge of the second section to form U-shapes along the length of the first edge;

shaping the second edge of the second section to form U-shapes along the length of the second edge, wherein the U-shapes are open to each other.

19. The method of claim 16, wherein the second section has a first edge and a second edge parallel to the first edge and perpendicular to the boundary, and wherein forming the filter support further comprises:

shaping two U-shape sections from a metal sheet, the U-shape sections each having a length about the length of the second section;

attaching a first U-shaped section to the first edge of the filter support; and

attaching a second U-shaped section to the second edge, wherein the U-shapes are open to each other.

20. A method of using a telecommunications equipment system, the method comprising:

inserting a filter support of a filter assembly into a filter-assembly slot in a chassis housing telecommunications equipment, wherein a filter held in the filter support is positioned in the filter-assembly slot;

removably attaching a cover plate to the chassis;

operating the equipment housed in the chassis; and

detaching the cover plate from the chassis while the equipment is operating; and

removing the filter and the filter support from the filter-assembly slot.

21. The method of claim 20, wherein the filter is a first filter, the method further comprising:

removing the first filter from the filter support;

inserting a second filter into the filter support;

re-inserting the filter support of the filter assembly into the filter-assembly slot in the chassis housing the operating telecommunications equipment, wherein the second filter is positioned in the filter-assembly slot; and

removably re-attaching the cover plate to the chassis.
