Title:
HEAT CONDUCTION SHEET AND HEAT RADIATOR USING THIS
Document Type and Number:
WIPO Patent Application WO/2019/130996
Kind Code:
A1
Abstract:
A heat conduction sheet is provided which can be placed against a heat generating element while sealing a graphite sheet and which, even when thin, has excellent heat conduction. The heat conduction sheet (11) is provided with a graphite sheet (12), a first insulation sheet (13) bonded on a first surface of the graphite sheet (12), and a second insulation sheet (14) bonded on the second surface of the graphite sheet (12), opposite of the first surface. A first adhesive material is provided on the surface of the first insulation sheet (13) facing the graphite sheet (12). The first insulation sheet (13) covers the entire outer periphery of the graphite sheet (12). A second adhesive material is provided on a first surface of the second insulation sheet (14), facing the graphite sheet (12), and a third adhesive material is provided on the second surface thereof, opposite of the first surface. Part of the second surface of the graphite sheet (12) is exposed from the second insulation sheet (14).
