▎ 摘　　要

NOVELTY - Graphite heat conducting component, comprises two layers of graphite heat conducting layers (1), and a buffer layer (2) arranged between the two graphite heat conducting layers. The buffer layer is provided with multiple guide holes (3). The guide hole is connected with the two graphene heat conducting layer. The guide hole is filled with a heat-conducting sizing agent. The buffer layer is made of foamed cotton and heat-conducting filler filled in the inner hole of the foamed cotton. The heat conducting filler is liquid metal. The foamed cotton is polyurethane foamed cotton, polyethylene foamed cotton, polyvinyl chloride foamed cotton, silica gel foamed cotton or polyimide foamed cotton. The heat-conducting sizing agent includes 25-40% graphite powder, 50-70% binder, and 5-10% dispersant. The binder is epoxy resin, polyurethane, acrylic resin or silicon rubber. USE - Graphite heat conducting component. ADVANTAGE - The heat-conducting performance of the buffer layer can be effectively improved while reducing the air thermal resistance of the foaming cotton. The heat conducting slurry has good heat conducting effect, providing further heat conducting channel for buffer layer, improving the heat conducting performance. The graphite heat conducting component in the application is prepared by the graphite sheet and the buffer sheet sequentially the form of overlapping, reducing the thickness of the single-layer single-foaming cotton, can reduce the influence of slurry in the guide hole to buffer layer compression resilience performance, and improving the buffer performance of heat conducting assembly. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is also included for the preparation method of the graphite heat conducting component. DESCRIPTION OF DRAWING(S) - The drawing shows a section view of the graphite heat conducting component. 1Graphite heat conducting layer 2Buffer layer 3Guide hole
