Abstract
The invention discloses a heat conducting plate. The heat conducting plate is characterized by being prepared from, by weight, 30-40% of 2000-mesh metal powder, 15-25% of puffed microbeads, 25-35% of heat conducting resin, 8-12% of macromolecular heat conducting powder and 3-6% of infiltration agent, wherein the heat conducting resin is epoxy resin and/or isocyanate resin, and the macromolecular heat conducting powder is reinforced carbon fiber powder. The heat conducting resin is stirred with the metal powder and the macromolecular heat conducting powder in air, then the infiltration agent and the puffed microbeads are added, vacuumizing is performed, then the mixture is put in a mold, and the mold is put in a levelling machine to perform pressure casting for forming. The heat conducting plate has the advantages of being uniform in heat conduction, high in heat conduction efficiency and low in cost.
