Patent ID: 8578605

Claim:
A method of manufacturing a heat dissipation device, comprising: providing at least one heat pipe comprising a condenser section having a planar outer surface; providing a heat sink comprising: a supporting surface defining at least one guiding line, the at least one guiding line having a width smaller than a width of the outer surface of the condenser section; a plurality of inner fins arranged side by side; and a pair of outer fins respectively arranged on two opposite sides of the plurality of inner fins, each of the outer fins comprising a main body and a flange extending perpendicularly from one side of the main body of each outer fin, and each of the plurality of inner fins comprising a main body and a flange extending perpendicularly from one side of the main body of each inner fin, the flanges of the outer fins each having an outer surface which is completely smooth, the at least one guiding line forming closed ends at two opposite ends thereof which are adjacent to the outer fins respectively; spreading an amount of solder on the supporting surface along the at least one guiding line to form at least one solder layer on the supporting surface, the at least one solder layer having a size not larger than a size of the outer surface of the condenser section; and attaching the outer surface of the condenser section of the at least one heat pipe to the at least one solder layer on the supporting surface of the heat sink.
