Three-dimensional net-shaped high thermal conductivity graphite framework structure and manufacture method thereof

A three-dimensional net-shaped high thermal conductivity graphite framework structure comprises at least two layers of graphite heat conduction films (12) and is characterized in that the number of connection points between every two adjacent layers of the graphite heat conduction films (12) is more than 5, and the distance between the every two connection points is more than 1mm. The thermal conductivity of the graphite heat conduction films (12) is 400-2400W/mK, and the thickness of each graphite heat conduction film (12) is 5-100 microns. The three-dimensional net-shaped high thermal conductivity graphite framework structure has very high thermal conductivity on the three-dimensional direction, and heat conduction materials have high thermal conductivity and strong mechanical strength. The requirement of fast heat conduction can be met, and the design requirement of a certain mechanical structure can be met. The three-dimensional net-shaped high thermal conductivity graphite framework structure can serve as a framework to be used with other materials in a compound mode, and whole thermal conductivity is improved.
