A heat-radiating device including a heat-radiator and a heat conductive rod for contacting with a heat source. The heat-radiator is composed of a heat conductive pipe body integrally formed by extrusion, a heat conductive column co-axially extending in the heat conductive pipe body and multiple heat-radiating vanes radially arranged between an outer periphery of the heat conductive column and an inner periphery of the heat conductive pipe body. The heat conductive rod is connected with the heat conductive column, whereby the column absorbs the heat conducted by the heat conductive rod from the heat source and the heat is spread from the center of the heat conductive column. The distance is shortest so that the heat can be quickly and evenly conducted to the respective vanes and the heat conductive pipe body and then quickly dissipated due to natural convection of air or forced convection by a fan.
