The heat pipe is used together with the cooling fan to improve heat dissipation efficiency. Conventionally, a heat sink in which a heat sink fin group is combined with a heat pipe is formed by combining a plurality of sets of heat sink fins of the same or different colors (for example, forming a different color by surface anodization) from top to bottom, or by multiple Groups of fins of the same or different colors are arranged from left to right and punched from top to bottom. However, this manufacturing method does not allow the heat sink fin group to completely contact the heat pipe, that is, there is always a gap between the heat sink fin hole and the heat pipe generated by the punching method, and the gap relatively affects the heat conduction rate, that is, the heat dissipation is affected. effectiveness. Furthermore, if the heat sink fin group and the heat pipe 201233971 are combined by welding, the conventional soldering method firstly solders the heat sink fin group to nickel. However, the heat-dissipating fin group will produce a nickel film after nickel plating, which can weld the heat-dissipating fin group made of aluminum and the heat pipe of the tube to each other, but if the nickel film is subjected to surface aiki (anti-oxidation surface) When the process is performed, the heat sink fin group and the heat pipe are not welded.

Therefore, by the above manufacturing method, it is possible to achieve a heat rate increase and a change in color without causing thermal resistance. The present invention also relates to a heat sink which is produced by the above-described manufacturing method, and the heat sink The utility model comprises a heat pipe, at least one heat dissipation fin set and at least one second heat dissipation fin set.
