Abstract: The present application discloses an axial flow wind wheel, including a wheel hub and blades; inner edges of the plurality of blades are connected to the wheel hub, and the blades are uniformly arranged at interval in a circumferential direction of the wheel hub; a suction surface of each blade is provided with rows of flow guide structures, and each row of flow guide structure includes flow guide ribs arranged along an arc corresponding thereto; and the arcs respectively corresponding to the rows of flow guide structures are concentric with an axis of the wheel hub, and are arranged at interval in a radial directional of the wheel hub. An air conditioner outdoor unit includes a heat exchanger, a driving motor, and the axial flow wind wheel.

Abstract: Disclosed are a fan apparatus and an air conditioner outdoor unit. The fan apparatus includes: a first wind wheel and a second wind wheel, axially arranged in an interval. A spacing S1 between the first wind wheel and the second wind wheel satisfies S1<(H1+H2)/2, where H1 is a length of the first wind wheel along the axial direction, and H2 is a length of the second wheel along the axial direction.

Abstract: The present disclosure relates to the field of air conditioners, and in particular to an air conditioning outdoor unit and an air conditioner therewith. The present disclosure provides an air conditioning outdoor unit, including: a case, where an air outlet is provided at a top of the case, and a compressor assembly is provided at a bottom of the case; a wind turbine, where the wind turbine is arranged at the top of the case and is located at a position of the air outlet; and an electronic control box, where the electronic control box is arranged at the case, and a distance between a bottom of the electronic control box and the bottom of the case is Z2, Z2?0.8×h, h being a height of the compressor assembly. In the air conditioning outdoor unit of the present disclosure.

Abstract: An air conditioner outdoor unit, including a housing, a heat exchanger, a fan wheel, an electric motor and a support, and the housing is provided with a first cavity and an air outlet in communication with the first cavity; the heat exchanger is arranged in the first cavity and connected to the housing; in a horizontal direction, the heat exchanger includes a first portion and a second portion which are opposite each other, a minimum distance S being provided between the first portion and the second portion; the support is arranged in the first cavity, is connected to the housing, and is located above the heat exchanger; the electric motor is in the first cavity and is arranged on the support; the fan wheel is in the first cavity, is connected to the electric motor, and has a diameter of D; and a first portion of the support is opposite the heat exchanger in a vertical direction, the minimum distance between the first portion and the heat exchanger in the vertical direction is L1, and when S<D, 0?L1?0.15D.
