The present application provides an air supply assembly, an air conditioner outdoor unit, and an air conditioner. The air supply assembly includes: a fan, which includes at least one fan blade having a rear edge of the fan blade and an outer edge of the fan blade; in which the outer edge of the fan blade is located on a side away from a rotational axis of the fan, and the rear edge of the fan blade is connected to the outer edge of the fan blade; the orientation of the rear edge of the fan blade is opposite to a rotational direction of the fan, and a vortex disturbing structure is provided on the rear edge of the fan blade; and a flow guide member having a flow guide channel; in which the flow guide channel is sleeved on an outer side of the fan.

Architectures and techniques are presented that can facilitate improved design and function of certain air handler devices. Architectures directed to an improved air handler device can be designed to improve temperature control demands such as, e.g., concurrently heat and cool air and reducing device dimensions (e.g., size, weight) that can reduce costs and mitigate shipping and installation difficulties. Architectures directed to U-bend structures can further reduce footprint on leasable space and provide improved acoustics, service access, and reduced energy consumption and infrastructure costs.
