Abstract
Abstract An audio/video electronic component cabinet includes a pair of side walls, a back wall, a front wall and a top; a plurality of component shelves extend between the side walls to the front wall but short of the back wall; a chimney formed along the back wall in the space between the ends of the shelves and the back wall receives wiring and exhausts hot air from the component; and an outlet in the top over the chimney vents the hot air from the chimney.

Claims Analysis
Total Claims: 11
Claim 1
Independent Claim
229 words
An audio/video electronic component cabinet for passively cooling electronic components comprising: a pair of side walls, a back wall, a front wall, and a top; as plurality of component shelves extending between said side walls to said front wall but short of said back wall; a drafting chimney formed along said back wall in the space between the ends of said shelves and said back wall for receiving wiring and exhausting hot air for the components; an outlet in said top over said chimney for venting the hot air from the chimney; a plurality of openings in said front wall proximate said shelves, each said opening larger than the component on the associated shelf for providing a plurality of effective openings in said front wall proximate said components for allowing cooling air to be drafted through the openings and past the components to cool the components by displacing air heated by the components; and a further opening in said front wall below said shelves to a chamber communicating with said chimney, said chamber having a bottom formed by a further component shelf, said further opening being larger than each of said effective openings for providing a draft of fresh air into and up through said chimney to create a pressure differential between the back of said cabinet and its front to draw the cooling air through said effective openings.

An audio/video electronic component cabinet for passively cooling electronic components comprising: a pair of side walls, a back wall, a front wall, and a top; as plurality of component shelves extending between said side walls to said front wall but short of said back wall; a drafting chimney formed along said back wall in the space between the ends of said shelves and said back wall for receiving wiring and exhausting hot air for the components; an outlet in said top over said chimney for venting the hot air from the chimney; a plurality of openings in said front wall proximate said shelves, each said opening larger than the component on the associated shelf for providing a plurality of effective openings in said front wall proximate said components for allowing cooling air to be drafted through the openings and past the components to cool the components by displacing air heated by the components; and a further opening in said front wall below said shelves to a chamber communicating with said chimney, said chamber having a bottom formed by a further component shelf, said further opening being larger than each of said effective openings for providing a draft of fresh air into and up through said chimney to create a pressure differential between the back of said cabinet and its front to draw the cooling air through said effective openings.
Claim 3
Dependent Claim
34 words
The audio/video electronic component cabinet of claim 1 in which said further shelf extends short of said back wall and is slidably extendable out of an retractable into said chamber for accessibility in use.
Claim 4
Dependent Claim
29 words
The audio/video electronic component cabinet of claim 1 in which said component shelves are slidably extendable out of an retractable into said cabinet for accessing the components and wiring.
Claim 5
Dependent Claim
28 words
The audio/video electronic component cabinet of claim 1 in which said front wall includes a door proximate said component shelves for easy accessibility of the components and wiring.
Claim 6
Dependent Claim
30 words
The audio/video electronic component cabinet of claim 4 in which said door has cutouts proximate the component shelves forming said openings for flush mounting of the components in the door.
Claim 7
Dependent Claim
28 words
The audio/video electronic component cabinet of claim 5 in which said door includes a removable panel for said cutouts for easy customization of said cabinet to different components.
Claim 8
Dependent Claim
47 words
The audio/video electronic component cabinet of claim 1 in which said front wall includes a door proximate said component shelves for easy accessibility of the components and wiring, said door extending over said chamber and having an opening corresponding to said further opening communication with said chamber.
Claim 9
Dependent Claim
79 words
The audio/video electronic component cabinet of claim 1 in which said front wall includes a door proximate said component shelves for easy accessibility of the components and wiring, said door extending over said chamber and having an opening corresponding to said further communication with said chamber, the lower portion of said door proximate the lower end of said chamber being independent of said door and attached to the front of said further shelf to partially mask said further opening.
Claim 10
Dependent Claim
46 words
The audio/video electronic component cabinet of claim 1, said cabinet further including an upper storage compartment below said top and above said component shelves but extending back only as far as said component shelves to allow said drafting chimney to pass behind said upper storage compartment.
Claim 11
Dependent Claim
19 words
The audio/video electronic component cabinet of claim 1 said cabinet further including a lower storage compartment below said chamber.
