Claims Analysis
Total Claims: 8
Claim 1
Independent Claim
144 words
Apparatus for mounting and cooling electronic devices comprising: a. an enclosure substantially rectangular in a first plane, b. means for forcing air longitudinally through said enclosure along the axis normal to said first plane, c. support beams traversing the interior of said enclosure parallel to said first plane, d. a plurality of support modules each comprising: i. a substantially rectangular plate member having substantially parallel upper and lower surfaces, ii. a lipped groove formed in one end surface of said plate member, iii. shroud means cooperating with said upper surface and said lower surface to form parallel conduits on opposite sides of said plate member, and vi. fins affixed to said upper and lower surfaces of said plate member within said conduits forming a plurality of parallel channels within said conduits, and e. means for removeably attaching said support modules to said support beams.
Claim 2
Dependent Claim
144 words
Apparatus for mounting and cooling electronic devices comprising: a. an enclosure substantially rectangular in a first plane, b. means for forcing air longitudinally through said enclosure along the axis normal to said first plane, c. support beams traversing the interior of said enclosure parallel to said first plane, d. a plurality of support modules each comprising: i. a substantially rectangular plate member having substantially parallel upper and lower surfaces, ii. a lipped groove formed in one end surface of said plate member, iii. shroud means cooperating with said upper surface and said lower surface to form parallel conduits on opposite sides of said plate member, and vi. fins affixed to said upper and lower surfaces of said plate member within said conduits forming a plurality of parallel channels within said conduits, and e. means for removeably attaching said support modules to said support beams.
Claim 3
Dependent Claim
17 words
Apparatus as defined in claim 1 wherein said support beams are disposed in a substantially vertical plane.
Claim 4
Dependent Claim
22 words
Apparatus as defined in claim 1 wherein said support beams are disposed in a plane which substantially deviates from the vertical plane.
Claim 5
Dependent Claim
25 words
Apparatus as defined in claim 1 including divider plates disposed substantially parallel to the floor of said enclosure and substantially equidistant from adjacent support beams.
Claim 6
Dependent Claim
20 words
Apparatus as defined in claim 4 including vertically disposed divider plates extending between at least two adjacent horizontal divider plates.
Claim 7
Dependent Claim
34 words
Apparatus as defined in claim 4 wherein said shroud means extends vertically in both directions from said plate member substantially the entire distance separating divider plates disposed on opposite sides of the plate member.
Claim 8
Dependent Claim
29 words
Apparatus as defined in claim 1 wherein said fins comprise convoluted sheet material, each convolution extending substantially vertically between the surface of said plate member and said shroud means.
