By arranging the shock-absorbing springs 8 around the cooling fan 9, the damping effect can be enhanced. The cooling fan 9 can be further buffered and damped by the buffer airbag 6 using the connecting plate 7, thereby enhancing the damping effect.

[0036] Working principle: by connecting the cooling fan 9 inside the structure, when the cooling fan 9 vibrates, the cooling fan 9 can be buffered and damped by multiple shock-absorbing springs 8 inside the protective shell 1. By arranging shock-absorbing springs 8 around the cooling fan 9, the damping effect can be enhanced. The cooling fan 9 can be further buffered and damped by the buffer airbag 6 using the connecting plate 7, thereby enhancing the damping effect. The sound-absorbing fluff 5 adhered to the silencer hole 3 and the sound-absorbing hole 4 can block and weaken the noise entering the silencer hole 3 and the sound-absorbing hole 4. The sound-absorbing hole 4 can reflect and absorb the noise entering therein, so that the noise gradually disappears and the noise generated is reduced.
