Novel graphite radiator and preparation method thereof
The invention discloses a novel graphite radiator and a preparation method thereof. The preparation method comprises the steps: heating asphalt to obtain asphalt liquid; adding nano-graphite powder into the asphalt liquid, and stirring, so that the nano-graphite powder is uniformly dispersed in the asphalt liquid to obtain mixed liquid; adding kaolin into the mixed liquid, stirring, and graduallycooling to obtain a pasty mixture; adding the paste mixture into a radiator mold, and heating the radiator mold to obtain a radiator blank; and under the protection of inert atmosphere, calcining theradiator blank to graphitize the asphalt in the radiator blank, thereby obtaining the novel graphite radiator. The novel graphite radiator prepared by the invention has super-strong corrosion resistance, is lower in price than a non-ferrous metal radiator, has better insulating property, and is suitable for high-voltage and high-current environments.
本发明公开一种新型石墨散热器及其制备方法，其中，制备方法包括步骤：对沥青进行加热处理，得到沥青液体；在所述沥青液体中加入纳米石墨粉并搅拌，使所述纳米石墨粉均匀分散在沥青液体中，得到混合液体；向所述混合液体中加入高岭土并搅拌，逐渐降温后，得到膏状混合物；将所述膏状混合物加入散热器模具中，并对所述散热器模具进行加热，得到散热器胚体；在惰性气氛保护下，对所述散热器胚体进行煅烧处理，使得所述散热器胚体中的沥青石墨化，制得所述新型石墨散热器。本发明制得的新型石墨散热器具有超强的耐腐蚀性能，价格比有色金属散热器低，其具有较佳的绝缘性能，适用于高电压、大电流环境。
