摘要： In a manufacturing method of a fin unit for a heat sink for dissipating a heat from a heat source, the fin unit includes a plurality of fins radially arranged about its center axis, and a fin supporting portion connecting inner ends of the fins and supporting the fins. First, metal is heated. The heated metal is extruded and/or drawn through a die to obtain a metal body. One of the die and the metal body obtained through the die is rotated relative to the other about a center axis of a die hole of the die. The metal body is then cut, thereby obtaining the fin unit.

摘要： A heat sink has a structure which enables the heat sink to be carried by a holding device in an automated production line. The heat sink includes a base portion at a center thereof and a finned portion around the base portion. The heat sink is arranged in contact with, or very close to, an object to be cooled, e.g., an MPU, and receives the heat generated in the object. The heat is then dissipated to ambient air from the fins. At an object-side end of the heat sink is provided a convex portion which has an engagement feature to be caught by the holding device while the heat sink is carried.
