Wherein the fin unit 3 is detachably mounted in the through hole 111, specifically, the detachable mounting of the fin unit 3 can be realized by adopting a screw connection mode. Therefore, in this embodiment, the heat dissipation mechanism is not an integral structure, but is formed by a plurality of independent fin units 3, so that if a certain fin unit 3 is damaged and needs to be replaced, the whole heat dissipation mechanism is not required to be replaced, and only the corresponding fin unit 3 is required to be removed for replacement.

As shown in fig. 2, the fin unit 3 extends at least partially to the outside of the heat dissipation side 11 to form a heat dissipation fin 34, and the fin unit 3 extends at least partially to the inside of the through hole 111 to form an installation portion 33, so that heat generated in the housing 1 can be directly transferred to the fin unit 3 and then dissipated by the fin unit 3, and the heat dissipation efficiency is better.
