The fin 211 includes a first ring 212, a support plate 213 disposed on the outside of the fin 211, and a second ring 214 disposed on the support plate 213. The fin 211 is provided with a plurality of fins 211, and the plurality of fins 211 are spaced apart and arranged in parallel. The second ring 214 is sleeved on the outside of the first ring 212. A gap 215 is provided between the first ring 212 and the second ring 214. The first ring 212 is provided with a groove 216, and the groove 216 is arranged along the axial direction of the first fin group 21.
[0031] The first fin group 21, the second fin group 22, and the third fin group 23 are arranged at intervals along the length direction of the frame 1, and then the heat pipe 3 is penetrated and arranged between the first fin group 21, the second fin group 22, and the third fin group 23, so that the heat of the heat pipe 3 is efficiently and quickly dissipated through the three fin groups 211.
