Abstract: A structure for assembling a heat sink assembly uses at least an interlocking device to assemble at lease a heat sink fin. The improvement in the interlocking devices comprises a female slot, a protruding hook, and an opening hole. Said protruding hook of each first heat sink fin wedges into said female slot of an adjacent first heat sink fin by the shape of said protruding hook corresponding to said female slot, and said protruding hook of each first heat sink fin having a barb portion for hooking into said opening hole of said adjacent first heat sink fin for interlocking completely in the vertical direction. Besides, the protruding hook further includes a protruding portion, said protruding portion having a T-shaped cross-section configuration is correspondingly equal to said female slot for interlocking completely in the horizontal direction. Therefore, the heat sink assembly provided by the present invention may be interlocked in both horizontal and vertical direction.
