Title: Method for manufacturing cylindrical radiator

Abstract: A method for manufacturing a cylindrical radiator that includes the step of drawing material to form an elongated blank material having a hollow cylindrical base section and multiple heat-radiating fins radially projecting from the outer circumference of the base section. Next, the elongated blank material is cut to form a plurality of blanks. Then, a top portion of each blank is bored to separate the top portions of the heat-radiating fins from each other.
