COMPRESSIBLE THERMALLY CONDUCTIVE ARTICLES

Abstract:

Disclosed is a compressible and thermally conductive material in the form of a sheet comprising a plurality of elongated walls substantially parallel in an x-y plane, wherein the elongated walls comprise particles of thermally conductive filler dispersed in a polymeric matrix material. Each of the elongated walls extends in a direction of thickness that slants from a bottom point to a top point, wherein adjacent elongated walls slant in alternate directions to a vertical line in the direction of thickness. In some embodiments, the thermally conductive sheet comprises a corrugated elastomeric sheet, having front and back surfaces, wherein the corrugated elastomeric sheet has a porosity of 0 to 25%; and wherein the corrugated elastomeric sheet is optionally embedded, at least partially, in a sheet of polymeric foam having a porosity of greater than 10%. Heat management assemblies comprising such compressible thermally conductive materials are also disclosed.
