Special Blades Design

  Waterdrop-shaped fan blade cross-section design

  We were inspired by the falling shape of water droplets anddesigned the fan blades to have a large head and a small tail and adouble-layer structure to minimize air resistance. Dawang engineerdrew on the cross-section design of aviation wings to make the fanblade cross-section more like a squashed water droplet, furtherReduce air resistance.

  30° angle of attack doubles air volume and strength

  After many tests, we found that the fan blade cross section has anangle of attack of 30° with the horizontal, which can significantlyincrease the air volume and achieve low-speed strong winds.However, if a traditional fan adopts this angle of attack, it will causestalling, air turbulence,increased noise and increased energyconsumption.

  Aerodynamic noise reduction

  Inspired by the continuous arc transition of eagle wings, wedesigned the fan with an upturned tail to enhance stability, reduceturbulence, and achieve flexible air movement. At the same time,.the continuous change of the angle of attack optimizes the powerconversion efficiency and wind feel, and uses aerodynamics toevenly distribute airflow, which can produce smooth and silentdiffused airflow at low speeds, effectively silencing and reducingnoise.
