In order to reduce the weight of the wind wheel and the load of a fan, the design of the existing wind wheel designs the blades into single circular arcs with equal thickness, so that the weight of the wind wheel is reduced, the load of a motor is reduced, and the noise of the fan is increased.
In order to solve the above technical problems, please refer to fig. 1 to 3, a wind wheel is provided in a first aspect of the present application, which has less noise during rotation.
Referring to fig. 1 to 3, the wind turbine includes a hub 10 and a plurality of blades 20, the plurality of blades 20 are fixed on a circumferential side of the hub 10, the blades 20 have an outer edge portion 21 far from the hub 10 along a radial direction of the hub 10, an arc-shaped sub-portion 211 having an arc-shaped structure is formed at an edge portion of the outer edge portion 21 far from the hub, and diameters of the arc-shaped sub-portions 211 are different along a circumferential direction of the hub 10.
The hub 10 is used for connecting the blades 20 and an external driving device, the hub 10 drives the plurality of blades 20 fixed on the periphery of the hub 10 to rotate under the drive of the external driving device, in this embodiment, the shape, structure, material and the like of the hub 10 are not limited, and the hub 10 can be specifically selected according to the working condition of an axial flow wind wheel, for example, the axial flow wind wheel is applied to an axial flow wind wheel or an air conditioner and the like, the hub 10 can be configured into a cylindrical structure with a simple structure, and the material can also be selected from plastics or light alloy and the like.
The blades 20 are important components of the wind wheel, whether the blades 20 have good high aerodynamic performance determines the working efficiency of the wind wheel, in the embodiment of the present application, the number of the blades 20 is not limited, any number of the blades 20 can realize the exhaust function of the wind wheel, and it can be understood that the blades 20 are uniformly distributed along the circumferential direction of the hub 10.
According to the wind wheel of the embodiment of the application, firstly, due to the existence of a blade tip gap (the distance between the blade tip of the axial flow fan and the guide ring), part of fluid flows from the pressure surface of the impeller to the suction surface of the impeller through the blade tip gap, and the leaked fluid forms a blade tip leakage vortex.
Since the leading edge of the blade 20 is first contacted by the fluid, i.e. the fluid flows faster at the leading edge portion 22 of the blade 20, the fluid gradually slows down as it flows from the leading edge portion 22 to the trailing edge portion 23, i.e. the fluid flows slowest at the trailing edge portion 23; the greater the diameter of the arc-shaped sub-portion 211, the smoother the shape of the outer edge portion 21 of the blade 20 at this location, the better the effect of reducing the leakage vortex on the blade tip is, therefore, as shown in fig. 1 to 3, in some embodiments of the present application, along the direction from the air inlet end 30 to the air outlet end 40 of the wind wheel, the diameter of the arc-shaped sub-portion 211 tends to decrease gradually from the front edge to the rear edge, so that the place with the largest diameter of the arc-shaped sub-portion 211 is used for reducing the leakage vortex on the blade tip generated by the front edge portion 22 with the largest flow velocity of the blade 20, so as to ensure that the arc-shaped sub-portion 211 can effectively reduce the leakage vortex generated by the blade 20, and the place with the smallest diameter of the arc-shaped sub-portion 211 is used for reducing the rear edge portion 23 with the slowest flow velocity of the blade 20.

In some embodiments of the present application, the ratio of the radius of the end of the arc-shaped sub-portion 211 near the wind outlet end 40 of the wind wheel to the radius of the wind wheel is greater than or equal to 0.0025 and less than or equal to 0.01, in this range, the ratio of the radius of the end of the arc-shaped sub-portion 211 near the wind outlet end 40 to the radius of the wind wheel is greater than or equal to 0.0025, the diameter of the arc-shaped sub-portion 211 is ensured not to be too small to weaken the strength of the leakage vortex, the ratio of the radius of the end of the arc-shaped sub-portion 211 near the wind outlet end 40 to the radius of the wind wheel is less than or equal to 0.01, the diameter of the arc-shaped sub-portion 211 is ensured to weaken the strength of the leakage vortex, and the structural design of the blade 20 at the outer edge portion 21 is not to be too large to be damaged, so as to ensure the aerodynamic performance of the blade 20.
In some embodiments of the present application, the ratio of the radius of the end of the arc-shaped sub-portion 211 near the wind outlet end 40 of the wind wheel to the radius of the wind wheel is greater than or equal to 0.005 and less than or equal to 0.008, for example, 0.006, 0.007, 0.009, further reducing the radius of the end of the arc-shaped sub-portion 211 near the wind outlet end 40 of the wind wheel, in this range, further ensuring that the diameter of the arc-shaped sub-portion 211 is not too small to weaken the strength of the leakage vortex, and not too large to damage the structural design of the blade 20 at the outer edge portion 21, so as to ensure the aerodynamic performance of the blade 20.
In some embodiments of the present application, the included angle of the arc-shaped sub-portion 211 is greater than or equal to 30 ° and less than or equal to 180 °, for example, 40 °, 55 °, 60 °, 75 °, 80 °, 95 °, 100 °, 115 °, 130 °, 145 °, 160 °, 170 °, it is understood that, under the same diameter, the greater the included angle of the arc-shaped sub-portion 211, the greater the arc-shaped surface of the arc-shaped sub-portion 211 is, the better the attenuation effect on the tip leakage vortex is, when the included angle of the arc-shaped sub-portion 211 is 30 °, it is ensured that the arc-shaped sub-portion 211 has enough arc-shaped surface to attenuate the tip leakage vortex, and the included angle of the arc-shaped sub-portion 211 is 180 ° which is the maximum included angle of the arc-shaped sub-portion 211, that is, the outer edge portion 21 is chamfered from the suction surface to the pressure surface to form the arc-shaped sub-portion 211, so that the tip leakage vortex can be attenuated to the maximum extent.
In some embodiments of the present application, the arc-shaped sub-portion 211 is chamfered from the pressure surface to the suction surface, and since a portion of the fluid flows from the pressure surface of the impeller to the suction surface of the impeller through the tip clearance, the portion of the leaked fluid forms tip leakage vortex, and thus, the chamfering of the arc-shaped sub-portion 211 from the pressure surface to the suction surface ensures that the arc-shaped sub-portion 211 must exist on the pressure surface to reduce tip leakage vortex generated by the blade 20.
Referring to fig. 1 to 2, in some embodiments of the present application, the blade 20 has a front edge 22 and a rear edge 23, the arc-shaped sub-portion 211 has a proximal end near the front edge 22 and a distal end near the rear edge 23, the intersection point of the front edge 22 and the outer edge 21 coincides with the proximal end, and the intersection point of the rear edge 23 and the outer edge 21 coincides with the distal end, so the outer edge 21 of the blade 20 is all configured as the arc-shaped sub-portion 211, at this time, the blade 20 has a good attenuation effect on the tip leakage vortex, and is suitable for generating the tip leakage vortex at one end of the outer edge 21 near the rear edge 23 of the blade 20.
