Abstract

The invention discloses a graphene heat sink coating device, which includes a workbench, a cleaning member located on the workbench and a coating member located on the workbench, the coating member includes a The coating roller for coating the heat sink, the support roll for supporting the heat sink, and the driving member for driving the rotation of the coating roll, both of the coating roll and the support roll are rotatably connected with the worktable. The coating device of the graphene heat sink of the present invention is convenient to improve the uniformity of graphene coating on the heat sink through the coating roller to coat the heat sink, thereby improving the heat dissipation capacity of the heat sink, and at the same time, reducing labor costs and improving work efficiency.

Description

technical field [0001] The invention relates to the field of production equipment for heat sinks, in particular to a coating device and a preparation process for graphene heat sinks. Background technique [0002] Graphene is a transparent and flexible conductor that can be used in various materials or devices; heat sink is a device for dissipating heat from electronic components that are prone to heat in electrical appliances, and is mostly made of aluminum alloy, brass or bronze. Shape, sheet, multi-sheet, etc. In order to improve the heat dissipation capacity of the heat sink, graphene is generally applied on the contact surface of the heat sink and electronic components to form a thin film, so that the heat emitted by the components can be more effectively conducted to the heat sink. Then it is distributed into the surrounding air through the heat sink. [0003] In related technologies, when coating heat sinks on some electronic components, graphene is first directly coa...
