Abstract A structure for mounting a large number of closely spaced heatgenerating devices of a relatively fragile nature, such as magnetic core memories for use in computer apparatus. The devices are affixed to a flexible heat conducting sheet having a pair of tabs projecting from opposite edges thereof. A relatively rigid metallic cover having corresponding tabs is attached to the heat conducting sheet at the tabs. The tabs on the cover are formed so as to project downwardly from the general plane of the cover so that when they are attached to the tabs of the heat conducting sheet a space is provided between the cover and the sheet in which the devices are positioned. A plurality of resilient members are placed at various points within such space and air is caused to flow in a non-turbulent fashion past the overall structure and, particularly, through the space between the cover and heat conducting sheet. Such a structure using a material having high heat conductivity provides for uniformity of heat distribution in the core assembly and good heat dissipation therefrom.
Means mounting a plurality of heat-generating devices comprising: a flexible heat conductive sheet, said devices being affixed thereto and said sheet having at least one tab member extending beyond an edge thereof; a rigid cover means with open sides having at least one tab member extending downwardly from the plane of said cover means and having a configuration substantially corresponding to that of said tab member of said flexible sheet, a portion of said tab member extending beyond an edge of said cover means; means retaining said tab member of said flexible sheet in good thermal contact with said tab member of said cover means, thereby providing a substantially open space between said cover means and said flexible sheet; and a plurality of resilient members disposed in said space spacing said cover from said sheet.

Means mounting a plurality of heat-generating devices comprising: a flexible heat conductive sheet, said devices being affixed thereto and said sheet having at least one tab member extending beyond an edge thereof; a rigid cover means with open sides having at least one tab member extending downwardly from the plane of said cover means and having a configuration substantially corresponding to that of said tab member of said flexible sheet, a portion of said tab member extending beyond an edge of said cover means; means retaining said tab member of said flexible sheet in good thermal contact with said tab member of said cover means, thereby providing a substantially open space between said cover means and said flexible sheet; and a plurality of resilient members disposed in said space spacing said cover from said sheet.
Claim 3
Dependent Claim
52 words
A mounting means in accordance with claim 1 wherein: said flexible sheet has two tab members extending beyond opposite edges of said sheet; and said cover means has two tab members extending beyond opposite edges of said cover means and having configurations corresponding to said two tab members of said flexible sheet.
Claim 4
Dependent Claim
26 words
Mounting means in accordance with claim 2 and further including means providing a flow of cooling air past said cover means and through said open space.
Claim 5
Dependent Claim
65 words
A mounting means in accordance with claim 3 wherein the tab members of said cover means extend downwardly by a preselected distance to provide said open space between said flexible sheet and the plane of said cover means whereby said cooling air flows substantially without turbulence through said open space and the heat-generating devices affixed to said sheet are prevented from touching said cover means.
Claim 6
Dependent Claim
38 words
A mounting means in accordance with claim 4 wherein each of said heat-generating devices is affixed to said flexible sheet by a heat conducting adhesive which contacts a substantial portion of the surface of each of said devices.
