Abstract: The present invention relates to a tower-type composite graphite heat sink and an LED lighting apparatus. According to the present invention, the tower-type composite graphite heat sink comprises: a main body of a cylindrical shape having a prescribed length; a plurality of heat radiation vanes integrally formed on the main body in a radial direction of the center of the cross section of the main body; and a heat pipe formed at the center of the main body in a longitudinal direction. The main body and the heat radiation vanes are constructed by mixing 65-75 wt% of graphite and 35-25 wt% of resins. Accordingly, limitations on thickness to maintain the strength required to form a reasonable height are eliminated. The heat sink is made of a composite graphite material and heat can be transferred vertically and horizontally due to an anisotropic heat transfer property to maximize heat radiation efficiency. Since the heat radiation vanes and the main body are integrally injection-molded, post-tasks such as separately manufacturing heat radiation vanes (fin) to couple the heat radiation vanes to the main body are not required. Therefore, production efficiency can be maximized and manufacturing costs can be reduced.
