▎ 摘　　要

NOVELTY - Production equipment of graphene heat sink comprises a stirring kettle (1), a pressing cover (2), a slitting knife die (3), a disc storage bucket hook (4), a cross steel shaft (5), a disc storage bucket, a heating device and a workbench. The stirring kettle, the pressing cover, the slitting knife die, and the disc storage bucket hook are respectively installed in the four directions of the cross steel shaft. The disc storage barrel includes a barrel wall and a base. The barrel wall and the base are detachably connected. A convex through-hole is provided in the center of the base. The height of the convex through-hole is consistent with the height of the barrel wall. The disc storage barrel is placed inside the heating device. USE - Used as production equipment of graphene heat sink. ADVANTAGE - The method solves the problem of high energy consumption, time consumption, low productivity, repeated program causing the film surface of the heat sink, and uneven problem of needle hole shape caused by the coating device single layer coating for multiple times. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is also included for production of graphene heat sink with a controllable thickness comprising (S1) mixing graphene slurry, aqueous resin and dispersant to obtain a mixed slurry, (S2) injecting the mixed slurry into the stirring tank for successive stirring and auxiliary defoaming, and then injecting into the disc storage barrel and sealing the pressing cover on the top of the disc storage barrel, (S3) heating device, sintering the mixed slurry under high temperature conditions, and cooling to room temperature naturally, (S4) rotating the cross steel shaft through the controller, and placing the slitting knife die on the top of the disc storage, (S5) checking the position by the laser, gradually cutting the slitter knife die downwards to form a graphene heat sink with a thickness of 1 mm and a width of 200 mm, and(S6) using the controller to rotate the cross steel shaft and placing the disc storage bucket hook. DESCRIPTION OF DRAWING(S) - The drawing shows a schematic representation of the production equipment of graphene heat sink.
