Abstract
The utility model relates to a centrifugal bidirectional wind wheel. The utility model comprises wind blades bent towards positive direction and wind blades bent towards negative direction, wherein, the wind blades bent towards the same direction are parallel to one another, and the wind blades incline on the axial cord of a centrifugal wind wheel. The utility model has reasonable structure and adopts the design of inclined wind blades, wind exhaust can be uniform, and thus, the noise of the wind exhaust is efficiently lowered; the utility model can also adopt the structure that the wind blades bent towards positive direction and the wind blades bent towards negative direction are separated from one another, and the quantity, the bending radian and the size of the wind blades bent towards positive direction and the wind blades bent towards negative direction are different to one another; in this way, wind exhaust efficiency can be improved, and the utility model is beneficial to lower the noise of the wind exhaust, optimize design and improve overall efficiency.
Description
The utility model relates to a kind of centrifugal Bidirection air vane.
At present, adopt the fan blade of positive and negative direction bending to realize the centrifugal Bidirection air vane of two-way air draft, adopt the structure of fan blade and rotor shaft line parallel, so air draft no matter forward or backwards, air draft is all inhomogeneous, thereby causes higher air draft noise.
The purpose of this utility model is to provide a kind of centrifugal Bidirection air vane that can effectively reduce the air draft noise.
Further purpose of the present utility model is to provide a kind of high efficiency centrifugal Bidirection air vane on the basis of realizing aforementioned purpose.
Be to realize the purpose of this utility model, the utility model by the following technical solutions: it comprises the fan blade of positive and negative direction bending, and homotropous fan blade is parallel to each other, and above-mentioned fan blade favours the axis of centrifugal wind wheel.
For realizing further purpose of the present utility model, the utility model can be simultaneously by the following technical solutions: each self-separation of the fan blade of described positive and negative direction bending.But the fan blade quantity of positive and negative direction bending equates, is spaced.The fan blade quantity of positive and negative direction bending also can be unequal, and the fan blade of several equidirectional bendings is that one group of fan blade with the bending of another opposite direction is spaced.The flexible radian of the fan blade of positive and negative direction bending is similar and different.The fan blade size of positive and negative direction bending also can be similar and different.
The fan blade of the positive and negative direction bending that the utility model is adjacent also can connect into " people " font at nearly wind wheel axis client.The flexible radian of the fan blade of positive and negative direction bending is similar and different.The fan blade of positive and negative direction bending also can be similar and different.
Owing to adopt technique scheme, the utility model is rational in infrastructure reliable, adopts the design of inclination fan blade, makes air draft even, thereby has reduced the air draft noise effectively.The fan blade of employing positive and negative direction bending is separated structures separately, can make crooked fan blade in the other direction when postive direction is rotated, and also plays suitable air draft effect, increased blast and air quantity under the same external condition, improved ventilation efficiency, vice versa, simultaneously, also be of value to reduction air draft noise.The fan blade quantity of positive and negative direction bending is unequal, crooked radian is different, vary in size, and when making the positive and negative rotation of centrifugal wind wheel, blast can be different with air quantity, to adapt to the different requirements to the positive and negative direction air draft, optimized design, improved overall efficiency.
The utility model will be further described below in conjunction with embodiment.
Fig. 1 is a plan view of the present utility model.
Fig. 2 is embodiment 1 a plan view.
