Abstract

The invention discloses a graphite heat conduction film compound block and a manufacturing method thereof. The graphite heat conduction film compound block comprises a graphite heat conduction film and an adhesive film, wherein a plurality of through holes are formed in the graphite heat conduction film, and all or part of the through holes are filled with a material which is the same as that of the adhesive film. When the graphite heat conduction composite film is used, the end surface of the graphite heat conduction film is jointed with a heat source of a device to be cooled, and the graphite heat conduction film is fixed at the position by the adhesive film through the through holes formed in the graphite heat conduction film, so that the bonding reliability is guaranteed, and the graphite heat conduction film is in contact with the heat source without a barrier; therefore, the heat resistance between the graphite heat conduction film and the heat source can be effectively reduced, and the thermal conductivity of the graphite heat conduction film compound block along the thickness direction can be increased.

Description

Technical field [0001] The invention relates to the field of high thermal conductivity graphite films, in particular to a graphite thermal conductivity film composite block and a manufacturing method thereof. Background technique [0002] Graphite is a kind of allotrope formed by carbon element, in which each carbon atom is combined with three adjacent carbon atoms through covalent bonds to form a hexagonal network structure. Due to its perfect molecular structure, electrons can move freely in the plane, which brings its unique thermal, electrical, chemical and other properties, which can be widely used in electronics, display, atomic energy and national defense industries. In recent industrial applications, graphite film materials have been widely used in the field of electronic display products such as mobile phones and tablet computers because of their thermal conductivity, ultra-thin shape and good bending resistance. . [0003] The high thermal conductivity graphite film is ...
