▎ 摘　　要

NOVELTY - The device has a heat-generating component mounted on a circuit board (8). An external heat dissipater is provided to dissipate heat to outside fof the cooling device. A graphite sheet (4) contains graphene, which is integrally provided on a surface of the external heat-dissipater. A heat conductive portion (5) contacts both a portion of the sheet and the component and has thermal conductivity capable of transferring heat from the component to the sheet. A shielding portion (6) is provided at a position between a portion of the circuit board and the sheet. USE - Cooling device for transferring heat from heat-generating components mounted on circuit board to graphite sheet for heat dissipation. ADVANTAGE - The device suppresses adhesion of small pieces of graphite sheet to a circuit board. DESCRIPTION OF DRAWING(S) - The drawing shows a cross-sectional view of the graphite sheet and the shielding portion.
