Abstract
The invention discloses an external diameter air intake noise reduction mechanism for an axial flow fan. The mechanism comprises a semispherical noise absorption end cover, an L-shaped noise reflection shield, an air filter screen, a diversion cone housing, an inorganic noise absorption filler and the like. The external diameter air intake noise reduction mechanism for the axial flow fan is assembled by filling the semispherical noise absorption end cover (1-1) on an integrally-welded noise absorption air intake end cover assembly (1) with the inorganic noise absorption filler (3), concentrically pressing a semispherical gland (2-2) with uniformly-distributed holes in the surface on an integrally-welded semispherical gland assembly (2) on the inner side (1-1-a) of the semispherical noise absorption end cover (1-1), uniformly welding the semispherical gland (2-2) at the corresponding contact positions of the spherical to form a concentric whole and concentrically and uniformly welding more than three radial fixed diversion cone supports (2-4) on the inner sides of more than three cross supports (1-3). The external diameter air intake noise reduction mechanism for the axial flow fan has the beneficial effects that the noise of the axial flow fan is greatly reduced, and the hearing loss of a person is reduced.
