Conductive cooling of a heat-generating electronic component

摘要

Conductive cooling of a heat-generating electronic component (12) disposable in spaced-apart adjacency with a surface (22) of a thermal dissipation member (14) to define a gap (24) of predetermined width (26) therebetween is provided by placing therebetween a curable composition formed of an electrically-insulating polymeric binder having thermally-conductive, electrically-insulating filler particles (36a-h) dispersed therein. At least a portion (36a-b) of the filler particles (36a-h) is of a maximum average diameter (38) about equal to the predetermined width (26) of the gap 924). A layer of the composition is disposable in conductive heat transfer contact with the electronic component (12) and the surface (22) of the thermal dissipation member (14), and is cured to form an interlayer (30) within the gap (24). At least a portion (36a-b) of the filler particles (36a-h) of the specified maximum average diameter (38) each substantially directly contact the electronic component (12) and the surface (22) of the thermal dissipation member (14) to establish thermally-conductive pathways effective to transfer heat from the electronic component (12) to the heat dissipation member (14).
