NOVELTY - The thermal guide plate manufacturing method of the present invention is executed in sequence: metal 3D printing manufacturing: through the layering method of metal 3D printing, the shell is manufactured with the required reinforcement on one side; the hydrophilic adhesion layer treatment: the use of deposition technology, Attach a good thermal conductor containing hydrophilic graphene to the surface of the reinforcing part and/or the shell to form a film-like hydrophilic adhesion layer; The two shells are combined into a heat conducting plate with a heat exchange chamber, the sparsely dense part of the reinforcing part defining the heat exchange chamber is a gaseous area, and the densely dense part of the reinforcing part is regarded as a liquid area. In this way, the method of the present invention produces a thin-layer micro-design, so that the thermal guide plate meets the heat dissipation requirements of light, thin, short, and small electronic devices, and has the advantages of high production efficiency and cost reduction. In addition, the hydrophilic adhesion layer of graphene improves the efficiency of heat conduction and reduces the probability of rusting of the thermal guide plate due to oxidation.
