Research and Application of Double Centrifugal Rotor Structure in Centrifugal Air Duct System

本文提出双离心风轮结构在离心风道系统中的研究及应用,通过对双层离心风轮中内风轮叶形渐开角度、内外风轮的设计间距大小,以及内风轮叶片多少的对比试验,探索双层离心风轮在外层离心风轮不变的情况下,内风轮叶形渐开角度,内风轮与外风轮间距及叶片多少对单层离心风轮的影响,寄希望通过离心风轮结构的创新设计,提升整机的舒适性及性能指标。

In this paper, the double centrifugal rotor structure in the research and application of centrifugal air duct system, based on the double centrifugal rotor in the leaf shape gradually open Angle, distance between inner and outer wind wheel design size, and the number of the wind wheel blade in contrast test, explore double centrifugal rotor under the condition of invariable in outer centrifugal wind wheel, the wind wheel blade shape gradually open Angle, inner wind wheel and outer wind wheel spacing and the number of the wind wheel blade impact on single centrifugal wind wheel blade, hope that through the innovative design of the centrifugal rotor structure, improve comfort and performance index of the engine.
