Example Embodiment
[0039] Such as Figure 1 to Figure 3 As shown, the heat sink 100 disclosed in the first embodiment of the present invention includes a base 110, a fin set 120, and a fastener 130. The base includes a bottom plate 111 and a plurality of first heat dissipation fins 112. A heat dissipation fin 112 is arranged on the bottom plate 111 at intervals, and a recess 113 is formed between adjacent first heat dissipation fins 112, wherein a plurality of first heat dissipation fins 112 are along a first direction (for example, the bottom plate 111 The long side direction) are arranged at intervals, and the opposite ends of each first heat dissipation fin 112 extend in a second direction perpendicular to the first direction (for example, the short side direction of the bottom plate 111), and extend beyond the bottom plate 111 Opposite two sides.
[0040] The fin set 120 includes a plurality of second heat dissipation fins 121. The length of the second heat dissipation fin 121 may be greater th...
