  • Heat sink and method of manufacture
    Patent number: 4588028
    Abstract: A heat sink is described that includes a base portion, and having a pair of heat radiating portions attached to the base portion. The heat radiating portions are each of sufficient width so that when bent along a line at roughly their midpoint, the unattached lower edges of such heat radiating portions will be disposed parallel to and in juxtaposition with the free edges of the base portion. Also, the method of manufacturing such heat sink includes, after punching the heat sinks from the sheet of material from which they are constructed, bending the heat radiating portions along the line extending generally through their midpoint and intersecting a corner of the base and then bending each of the heat radiating portions along an edge of the base to a position wherein the heat radiating portions are disposed at approximately 90 degrees to the base portion.
