[0002] In recent years, with the continuous development of electronic technology, electronic products are constantly updated, the size of their working components is getting smaller, the speed and efficiency of their work are getting higher, and the heat generation is getting higher. Therefore, it is not only required to be equipped with corresponding heat dissipation devices, but also to ensure that the heat dissipation devices have stronger heat dissipation capabilities to ensure the reliability of product performance and extend its service life; graphite thermal conductive heat dissipation materials, due to their unique low density (relative to metals) and high thermal conductivity and heat dissipation coefficient and low thermal resistance, have become the preferred material for modern electronic products to solve thermal conductive heat dissipation technology. Graphite heat sinks can conduct heat evenly in both horizontal and vertical directions. The lamellar structure can better adapt to the surface of any product and can effectively conduct heat and dissipate heat in horizontal and vertical directions. The production of graphite sheets first involves impregnating polyamic acid into a void-forming sheet formed into a mesh or non-woven fabric to form a sheet; next, the formed sheet is heat-treated to imidize the polyamic acid, thereby producing a polyimide sheet having polyimide and a void-forming sheet disposed inside the polyimide; and then heat-treating a polymer film at a high temperature to obtain a graphite sheet. In the prior art, the graphite sheet heat treatment equipment does not cool at a reasonable cooling rate after high-temperature treatment, resulting in reduced quality of the graphite sheet.
