A thin flexible heat transfer device for transferring heat from a heat source to a heat sink which may be located a substantial distance apart from each other. The heat transfer device includes a thin sheet of a non-structural, high thermal conductivity core material consisting of pyrolytic graphite or highly ordered pyrolytic graphite of a thickness between 2 microns and 2 mm and a pair of flexible face sheets each of a metallic composition having a maximum thickness of less than 25 mils disposed upon opposing surfaces of said core material to form a sandwich construction in cross section with the sheet of core material having a width smaller than the width of said face sheets such that the face sheets overlap the width of said core material around the perimeter of the device for enclosing and sealing the core material there within.

[ What is claimed is:] [1.] A thin flexible heat transfer device of indefinite length for transferring heat from a heat source to a heat sink which may be located a substantial distance apart from one another comprising:a thin sheet of a non-structural, high thermal conductivity core material consisting of pyrolytic graphite or highly ordered pyrolytic graphite having an in-plane thermal conductivity of greater than 200 W/mK and a thickness of between 2 microns and 2 mm;a pair of flexible face sheets each of a metallic composition having a maximum thickness of less than 25 mils disposed upon opposing surfaces of said core material to form a sandwich construction in cross section with the sheet of core material having a width smaller than the width of said face sheets such that the face sheets overlap the width of said core material and with said face sheets being bonded to one another at least around the perimeter of said device for enclosing and sealing said core material there within.
