In view of this, the present invention is directed to a fan guard, which improves the wind gathering capability of the fan guard and enhances the overall power effect of the fan guard.
The utility model adopts the following scheme:
the utility model provides a fan cover, is including the cover body and the flange that are used for surrounding the fan, the surface middle part of the cover body is provided with central circle, the cover body includes along many ribs that have the turn that the central circle radial distribution has and centers on central circle radial distribution just has gapped a plurality of ring shape and gathers the fan lath, and is a plurality of the rib with a plurality of gather fan lath cross connection and constitute the cover body, gather the inboard of fan lath and be face of cylinder or conical surface, and connect and be in the diameter of a plurality of wind laths that gather on the rib turn increases gradually and is the echelonment and distributes.
The utility model also has the following preferred design:
this reality is novel flange joint is in the end of each rib turn of the cover body, the flange is used for the installation of fan cover fixed.
The cover body and the flange are integrally formed.
The flange is a disc-shaped flange with a plurality of straight edge cuts along the circumferential direction, the area of the flange is reduced through the straight edge cuts, and the installation space is saved.
The inlet of the windward side of the wind gathering plate strip is provided with the chamfer, so that the wind resistance can be further reduced, the noise is reduced, and the air flux is increased.
The central ring is provided with a mounting seat connected with a motor.
The utility model has the following beneficial effects:
1. the fan cover is provided with the wind gathering strip, the inner side of the wind gathering strip is designed into a cylindrical surface or a conical surface, the air flow guiding capacity and the wind gathering capacity of the fan cover are enhanced, the diameters of the plurality of wind gathering strips connected to the rib bending parts are gradually increased and distributed in a step shape, the structural strength of the fan cover is enhanced on the premise of not reducing the ventilation volume, and the safety performance of the fan cover is improved.
2. The flange of the present invention has a straight cut edge design to save installation space.
3. The inlet of the windward side of the wind gathering plate strip is provided with the chamfer, so that the wind resistance is reduced, the noise is reduced, and the air flux is increased.
