description The utility model relates to an air outlet flow guide cover, a mixed-flow fan assembly and air conditioning equipment. The outer wall face of the air outlet flow guide cover is a rotation face gradually shrinking in the air outlet direction and comprises a first section, a second section and a third section which are sequentially distributed on the rotation axis of the rotation face in the air outlet direction. The outer wall face of the air outlet flow guide cover is designed to be a three-section type curved surface with the meridians being the line segment, the arc and the parabola, according to the Coanda effect, air flow can be effectively attached to the outer wall face of the flow guide cover, the air outlet speed and distribution are reconfigured, and therefore the good air outletflow guide performance is obtained, and eddy noise is effectively reduced. When applied to the mixed-flow fan, the embodiment of the utility model can effectively improve the air outlet uniformity ofthe mixed-flow fan and mee
