Abstract (en)
[origin: CN211230992U] The utility model relates to an air blower shell component and an air blower. The blower housing part (1) is provided with a housing (2) and a fixing flange (3) extending outwards from the housing (2)in the radial direction. A plurality of fixing points (4) are distributed on the fixing flange along the circumferential direction; the fixing point is used for fixing the blower shell part (1); wherein a radial rib (5) is formed between the housing (2) and the fastening point (4), said radial rib extending linearly in the radial direction along the fastening flange (3), wherein the radial ribs (5) intersect tangential ribs (6) extending along the fastening flange (3), each tangential rib extending tangentially to the housing (2) between two of the fastening points (4) and the two fastening points (4) being connected in each case. The bending rigidity of the air blower shell component is very high.
