Abstract

An enclosure panel for covering the access opening in an equipment compartment includes a main panel body which is constructed and arranged so as to attach directly to the equipment compartment in such a way as to substantially cover the access opening. The main panel body defines a plurality of oblong slots which are arranged into a plurality of side-by-side columns wherein each column is configured with a substantially uniform herringbone pattern. The herringbone pattern provides a unique and preferred compromise between a uniform pattern of oblong slots arranged in columns and rows and a uniform pattern of circular openings arranged in staggered rows and columns. By use of the uniform herringbone pattern the open area for preferred cooling air flow is achieved while at the same time maintaining the structural strength and integrity of the enclosure panel.

Claims

1. An enclosure panel for closing an access opening in a compartment with a heat-generating and noise-generating component therein, said enclosure panel comprising:

a main panel body constructed and arranged to be attachable to said compartment so as to substantially cover said access opening;

wherein said main panel body defines an insert opening and said insert opening has an insert opening cover; and

a plurality of oblong slots defined by said insert opening cover, said plurality of oblong slots arranged into a plurality of columns, each column being configured with a substantially uniform herringbone pattern.

2. The enclosure panel of claim 1 wherein said enclosure panel is fabricated out of a fiberboard material.

3. The enclosure panel of claim 1 wherein said enclosure panel is fabricated out of a plastic material.

4. The enclosure panel of claim 1 wherein said enclosure panel is fabricated out of metal.

5. The enclosure panel of claim 4 which further includes a vibration damping panel applied to said main panel body.

6. The enclosure panel of claim 1 wherein each oblong slot has a length dimension and a width dimension, the length to width ratio being substantially 2:

1.

7. The enclosure panel of claim 6 wherein said enclosure panel is fabricated out of a fiberboard material.

8. The enclosure panel of claim 7 further including a thickness of acoustical insulation applied to said main panel body.

12. The enclosure panel of claim 1 wherein said main panel body is fabricated out of a fiberboard material and said insert opening cover is fabricated out of metal.

13. The enclosure panel of claim 1 wherein said main panel body is fabricated out of a fiberboard material and said insert opening cover is fabricated out of a plastic material.

9. A method of fabricating an enclosure panel for the access opening of an equipment compartment, said method comprising the following steps:

providing a sheet of panel material;

blanking out an enclosure panel from said sheet of panel material;

cutting an insert opening in said enclosure panel blank;

providing an insert opening cover;

punching a plurality of oblong slots in said insert opening cover, said plurality of oblong slots being arranged into a substantially uniform herringbone pattern; and

attaching said insert opening cover over said insert opening.

10. A method of fabricating an enclosure panel for the access opening of an equipment compartment, said method comprising the following steps:

providing a sheet of panel material;

cutting an insert opening in said sheet of panel material;

blanking out an enclosure panel from said sheet of panel material, said enclosure panel including said insert opening;

providing an insert opening cover;

punching a plurality of oblong slots in said insert opening cover, said plurality of oblong slots being arranged into a substantially uniform herringbone pattern; and

attaching said insert opening cover over said insert opening.

11. A method of fabricating an enclosure panel for the access opening of an equipment compartment, said method comprising the following steps:

providing an enclosure panel with an insert opening therein;

providing an insert opening cover;

punching a plurality of oblong slots in said insert opening cover, said plurality of oblong slots being arranged into a substantially uniform herringbone pattern; and

attaching said insert opening cover over said insert opening.
