Abstract

The invention provides a preparation method of a heat dissipation layer of a heat sink as well as a heat sink. The preparation method comprises the following steps: cleaning the surface of a heat sink, and placing the cleaned heat sink in a vacuum high temperature box; filling the vacuum high temperature box with methane, and judging whether gas in the vacuum high temperature box meets heating reaction conditions; if yes, heating the vacuum high temperature box, so as to control the methane to be heated and decomposed into carbon and hydrogen; performing cooling and pressure relief on the vacuum high temperature box, so as to control the carbon to adsorb graphene and form a graphene heat dissipation layer, and judging whether the graphene heat dissipation layer meets carbon adsorption completion conditions; and if yes, taking out the heat sink. The preparation method is designed by adopting a method of generating a carbon source by heating and decomposing the methane, so that the generated graphene can be effectively and directly bonded with the surface of the heat sink, other materials like adhesive do not exist in the middle, heat of the heat sink can be fully transferred onto the graphene heat dissipation layer, and heat dissipation effect of the heat sink is improved.

Description

technical field [0001] The invention belongs to the field of radiators, in particular to a method for preparing a heat dissipation layer of a radiator and a radiator. Background technique [0002] The current radiators are all made of metal materials to increase the surface area as much as possible, so that they can be mounted on the surface of the heating device, so as to achieve the effect of dissipating the heat emitted during the heating period. With the emergence of graphene, many people gradually pay attention to this new material. Because graphene has super thermal conductivity and electrical conductivity. Therefore, it is also concerned by the heat dissipation market, and it is hoped that its excellent heat conductivity can help solve the problem of heat dissipation. [0003] For this reason, graphene heat dissipation coatings are popular. The main method is to stir the graphene in the paint, and then apply the graphene paint on the surface of the radiator to form...
