Abstract
Abstract A cooling structure for pressure mounting electrical components having opposed contact surfaces wherein spring clamp means electrically insulated from and in clamping engagement with the edges of oppositely disposed heat dissipating members urges the members together to provide a pressure mounting heat sink for an electrical component disposed therebetween; the spring clamp means externally applying and maintaining a predetermined force on the component to effect the proper electrical and thermal contact between the component and the heat dissipating members.

Claims Analysis
Total Claims: 5
Claim 1
Independent Claim
157 words
A cooling structure for pressure mounting an electrical component having opposed contacting surfaces comprising: a. a pair of heat transfer members adapted to be disposed in opposed relationship, b. each of said heat transfer members having a base; c. each base having an inner parallel face in intimate contact with the contacting surfaces of said electrical component; d. laterally extending lugs fixed to said base and extending laterally therefrom, each lug having a channel portion extending longitudinally of said base; e. spring clamp means having ends overlying said lugs urging said heat transfer members toward each other and into intimate engagement with said electrical components; and f. and electrical insulation between said clamp means and said lugs whereby said heat transfer members are electrically isolated from each other, said electrical insulation comprising a member fitting into said channel and having portions mating with grooves on each side of said lug to secure the insulation to said lug.
Claim 2
Dependent Claim
157 words
A cooling structure for pressure mounting an electrical component having opposed contacting surfaces comprising: a. a pair of heat transfer members adapted to be disposed in opposed relationship, b. each of said heat transfer members having a base; c. each base having an inner parallel face in intimate contact with the contacting surfaces of said electrical component; d. laterally extending lugs fixed to said base and extending laterally therefrom, each lug having a channel portion extending longitudinally of said base; e. spring clamp means having ends overlying said lugs urging said heat transfer members toward each other and into intimate engagement with said electrical components; and f. and electrical insulation between said clamp means and said lugs whereby said heat transfer members are electrically isolated from each other, said electrical insulation comprising a member fitting into said channel and having portions mating with grooves on each side of said lug to secure the insulation to said lug.
Claim 3
Dependent Claim
74 words
The cooling structure recited in claim 1 wherein said electrical insulation comprises a layer of electrically insulating material disposed adjacent said spring clamp means opposite ends of each of which extend longitudinally along a major portion of and engage with the extending portions of oppositely disposed heat transfer members for urging such members together and effecting the preselected pressure contact between the heat transfer members and the opposed contacting surfaces of said electrical component.
Claim 4
Dependent Claim
20 words
The cooling structure recited in claim 2 wherein each of said heat transfer members is an integral, extruded metal unit.
Claim 5
Dependent Claim
38 words
The cooling structure recited in claim 3 wherein said layer of electrically insulating material comprises separate extruded members one operatively fitted about each of said longitudinally and laterally extending portions at the sides of said heat transfer members.
