The invention discloses a preparation method of a heat conductor, which comprises the following steps: S1, selecting aluminum nitride powder, copper powder and glass powder, loading into a mold, and carrying out hot press molding to prepare a spiral green body; s2, the spiral blank is fed into a high-temperature furnace to be sintered; and S3, the sintered spiral blank is cooled, and the sintered heat conductor is formed. A heat conductor comprises a main body and an inserting part located on the upper portion of the main body. And fins are wound on the outer surface of the main body and spirally extend to the direction of the inserting part around the outer surface of the main body. The invention has the advantages of low cost, easily available raw materials, simple process and high heat conductivity coefficient. 本发明公开了一种导热体的制备方法，包括以下步骤：S1，选用氮化铝粉、铜粉和玻璃粉，装入模具中热压成型，制成螺旋坯体；S2，将所述螺旋坯体送入到高温炉内进行烧结；S3，将烧结后的所述螺旋胚体冷却，形成烧制完毕的导热体。一种导热体，包括主体以及位于主体上部的插接部；主体的外表面上绕设有翅片，翅片绕主体外表面向插接部方向螺旋延伸。本发明具有成本便宜、原料易得、工艺简单和高导热系数的优点。
