Method for manufacturing multiple structure and high-heat radiation parts by controling packing density of carbon material, and multiple structure and high-heat radiation parts by manufactured thereof

摘要

The present invention relates to a method for manufacturing a multi-structure high heat dissipation component by controlling the filling density of a carbon material, and to a multi-structure high heat dissipation component manufactured thereby, having a relatively smaller diameter than the first carbon material powder and the first carbon material powder. A mixing step of forming a mixture by mixing a carbon material comprising a second carbon material powder and a binder pitch, a hot forming step of forming a molded body by molding the mixture through a hot forming process, and cooling the molded body after heat treatment The technical gist is to include a graphitization step of manufacturing a graphitized pitch/carbon material molded body. Accordingly, it is possible to obtain an effect of increasing the thermal conductivity and strength in the horizontal and vertical directions by improving the filling density through bimodal distribution using carbon materials of different diameters.
