The invention discloses a wind wheel, a fan and refrigeration equipment. The wind wheel comprises a hub comprising an inner wheel part of which one part is recessed toward an air outlet side so as to delimit a recess part, and the inner wheel part is provided with an axle hole applicable for a motor shaft to penetrate through; an outer wheel part surrounding the outer side of the inner wheel part and connected to the peripheral edge of the inner wheel part; and a plurality of blades separately connected to the peripheral wall of the outer wheel part, wherein the concave depth of the recess part is h, 4 mm<=h<=6 mm. According to the embodiment in the invention, the wind wheel is beneficial to increasing the effective coverage area between the blades and an air guide ring of the refrigeration equipment, and the air supply volume of the blades is increased; and the working efficiency of the wind wheel is improved.
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, the effective coverage area of the wind wheel and the air guide ring of the refrigeration equipment is small, the air supply volume of the wind wheel is small, and the working efficiency is low.
