WIPO Patent Application WO/2022/073454
Kind Code:
A1
Abstract:
A fan apparatus (100) and an air conditioner outdoor unit (10). The fan apparatus (100) comprises a first wind wheel (110) and a second wind wheel (120) that are axially disposed at an interval. The spacing S1 between the first wind wheel (110) and the second wind wheel (120), the length H1 of the first wind wheel (110) in the axial direction, and the length H2 of the second wind wheel (120) in the axial direction satisfy the following relationship: S1<(H1+H2)/2, so that a better coordination relationship can be achieved between the first wind wheel (110) and the second wind wheel (120), and noise is lower when a relatively large volume of air is generated at relatively low energy consumption.
