The invention discloses a wind wheel, a fan and refrigerating equipment. The wind wheel comprises a hub; the hub comprises an inner wheel part, an outer wheel part, an annular projection part, multiple blades, and a turbulent rib, wherein one part of the inner wheel part is recessed in a direction towards an exhaust side to define a concave part; the inner wheel part is provided with a shaft hole for enabling a motor shaft to penetrate through; the outer wheel part is encircled on the outer side of the inner wheel part, and is connected to the outer peripheral edge of the inner wheel part; the projection part is arranged in the concave part, and is projected to a windward side; the projection part is arranged by surrounding the shaft hole in the peripheral direction of the hub; the multiple blades are connected to the outer peripheral wall of the outer wheel part at intervals; and the turbulent rib is connected between the outer peripheral wall of the projection part and the inner peripheral wall of the concave part to disturb air currents fed in the concave part. The wind wheel can reduce the vortex strength near the hub to lower the noise.
Description
technical field [0001] The invention relates to the technical field of refrigeration, in particular to a wind wheel, a blower fan and refrigeration equipment. Background technique [0002] In the related art, when the motor drives the wind wheel to rotate, eddy currents are likely to be generated near the hub of the wind wheel. The work efficiency of the wind wheel is low, the noise is large, the air output is small, and the heat exchange capacity of the entire refrigeration equipment is poor. Moreover, the reliability of cooperation between the motor shaft and the wind wheel is low. Contents of the invention [0003] The present invention aims to solve at least one of the technical problems existing in the prior art. For this reason, the present invention proposes a wind wheel, which is beneficial to reduce the vortex intensity near the hub, reduce noise, and increase air output. [0004] The present invention also proposes a fan comprising the above-mentioned wind whee...
