  • With reference to FIG. 9, multiple heat dissipating fins (90) in accordance with the prior art are disposed in parallel and each heat dissipating fin (90) has two opposite edges and two pairs of fastening mounts (91). The pairs of fastening mounts (91) are respectively formed on and protrude perpendicularly from the opposite edges of the heat dissipating fin (90) and each fastening mount (91) has a protrusion (92) and a cavity (93). The protrusion (92) is formed on the fastening mount (91). The cavity (93) defining the fastening mount (91) corresponds and opposite to the protrusion (92) of the fastening mount (91). When the heat dissipating fins (90) are formed into a heat sink, the protrusion (92) of the fastening mount (91) of one heat dissipating fin (90) is mounted on a corresponding cavity (93) of the fastening mount (91) of an adjacent heat dissipating fin (90).
  • However, due to the protrusions (92) and cavities (93) of the fastening mount (91) are easily loosened so the heat dissipating fins (90) may be accidentally separated during production, transportation and distribution of the heat sink.
  • To overcome the shortcomings, the present invention provides a heat dissipating fin for a heat sink to mitigate or obviate the aforementioned problems.
    • SUMMARY OF THE INVENTION
