Abstract
Abstract A plurality of electronic modules are mounted in a housing having conduitsor carrying coolant. Each electronic module is mounted in channel grooves in a pair of side plates and springs are provided in each groove for upwardly biasing each module. A top cold plate is forced downwardly by a screw-operated wedge plate and the cold plate engages a metal frame on each electronic module. The springs in the channel grooves are compressed and apply a force which insures good contact between the cold plate and each frame of each module thereby facilitating transfer of heat away from each electronic module.

Claims Analysis
Total Claims: 10
Claim 1
Independent Claim
145 words
A modular electronic system comprising, a case having a top, bottom and a plurality of sides, a support assembly slidably mounted in said case and having at least two side plates, each having a plurality of spaced grooves therein, spring means in each said groove, a plurality of electronic modules each having a metallic frame with the ends of each said metallic frame being slidably mounted in opposed grooves in said side plates and supported by said spring means, a metallic top plate positioned between said top of said case and said metallic frames of said electronic module, means for moving said top plate into engagement with each frame of each electronic module whereby said spring means are depressed and provide a biasing force to engage said frames with said metallic top plate, and means for cooling said side plates and said metallic top plate.
Claim 2
Dependent Claim
145 words
A modular electronic system comprising, a case having a top, bottom and a plurality of sides, a support assembly slidably mounted in said case and having at least two side plates, each having a plurality of spaced grooves therein, spring means in each said groove, a plurality of electronic modules each having a metallic frame with the ends of each said metallic frame being slidably mounted in opposed grooves in said side plates and supported by said spring means, a metallic top plate positioned between said top of said case and said metallic frames of said electronic module, means for moving said top plate into engagement with each frame of each electronic module whereby said spring means are depressed and provide a biasing force to engage said frames with said metallic top plate, and means for cooling said side plates and said metallic top plate.
Claim 3
Dependent Claim
22 words
A modular electronic system as set forth in claim 1 wherein said top plate is supported by springs on said side plates.
Claim 4
Dependent Claim
50 words
A modular electronic system as set forth in claim 1 wherein said means for moving said top plate includes at least one wedge surface on said top plate and a screw-operated plate having a complementary wedge surface in engagement with said at least one wedge surface on said side plates.
Claim 5
Dependent Claim
30 words
A modular electronic system as set forth in claim 1 wherein said spring means in each said groove comprises a plurality of parallel stacks of belleville washers stacked in series.
Claim 6
Dependent Claim
33 words
A modulator electronic system as set forth in claim 1 wherein said means for cooling said top plate comprises passages in said top plate and means for circulating cooling liquid through said passages.
Claim 7
Dependent Claim
156 words
A modular electronic system comprising, a case having a top, bottom and a plurality of sides, a support assembly slidably mounted in said case and having at least two side plates, each having a plurality of spaced grooves therein, a plurality of belleville washers in each said groove, said belleville washers being arranged in parallel stacks and stacked in series, a plurality of electronic modules each having a metallic frame with the ends of each said metallic frame being slidably mounted in opposed grooves in said side plates and supported by said belleville washers, a metallic top plate positioned between said top of said case and said metallic frames of said electronic modules, said metallic top plate having at least one wedge surface thereon, a screw-operated wedge plate having a complementary wedge surface in engagement with said wedge surface on said metallic top plate, and means for cooling said side plates and said metallic top plate.
Claim 8
Dependent Claim
156 words
A modular electronic system comprising, a case having a top, bottom and a plurality of sides, a support assembly slidably mounted in said case and having at least two side plates, each having a plurality of spaced grooves therein, a plurality of belleville washers in each said groove, said belleville washers being arranged in parallel stacks and stacked in series, a plurality of electronic modules each having a metallic frame with the ends of each said metallic frame being slidably mounted in opposed grooves in said side plates and supported by said belleville washers, a metallic top plate positioned between said top of said case and said metallic frames of said electronic modules, said metallic top plate having at least one wedge surface thereon, a screw-operated wedge plate having a complementary wedge surface in engagement with said wedge surface on said metallic top plate, and means for cooling said side plates and said metallic top plate.
Claim 9
Dependent Claim
22 words
A modular electronic system as set forth in claim 6 wherein said top plate is supported by springs on said side plates.
Claim 10
Dependent Claim
33 words
A modulator electronic system as set forth in claim 6 wherein said means for cooling said top plate comprises passages in said top plate and means for circulating cooling liquid through said passages.
