Abstract

The invention discloses a fan device and an air conditioner outdoor unit, the fan device comprises a first wind wheel and a second wind wheel which are axially arranged at an interval, and the distance S1 between the first wind wheel and the second wind wheel, the length H1 of the first wind wheel in the axial direction and the length H2 of the second wind wheel in the axial direction meet the following relation: S1lt; and (H1 + H2) / 2, a better matching relation between the first wind wheel and the second wind wheel can be achieved, and under the condition of lower energy consumption, the noise is lower while larger air volume is generated.

Description

technical field [0001] The invention relates to the technical field of air conditioners, in particular to a fan device and an air conditioner outdoor unit. Background technique [0002] As a necessary household appliance, air conditioner has a direct impact on people's daily life in terms of its function and quality. Existing air conditioners usually use an axial flow fan system to provide circulating air volume for the outdoor unit to heat the heat exchange of the heat exchanger, and the air volume is closely related to the performance of the outdoor unit. [0003] The inventors of the present application have found in long-term research and development that the current air conditioner outdoor unit generally adopts a fan system with a single wind wheel, and there is a large part of the rotational velocity component along the circumferential direction of the air outlet airflow, and the static pressure efficiency is low, which can improve the air volume. At the same time, mo...
