Abstract

The invention discloses a carbon fiber composite material axial flow fan impeller. Two or more carbon fiber composite material vanes arranged on the outer surface of a cylindrical metal impeller hub, a carbon fiber composite material vane and a metal impeller hub are connected in an equally-dividing mode. The cylindrical metal impeller hub is arranged on an output shaft of a motor through a center hole thereof. An impeller rotates at high speed under driving of the motor. Air is pushed to enter one end of an impeller rotating center shaft and be output from the other end of the impeller rotating center shaft, and axial wind is generated. According to the bending stress and the stretching stress on the vanes, the designability of composite material intensity is used, through the optimized combination design of the carbon fiber laying angle and the composite layer number, stress distribution on the vanes is reasonable, weight is low, multiple materials are saved, the carbon fiber resin composite material impeller is used, compared with the background technology, weight is lowered by at least 60%, noise is lowered, corrosion resistance is improved, impeller service life is prolonged, and operation energy loss is lowered.

Description

technical field [0001] The invention relates to an axial flow fan impeller, in particular to a carbon fiber composite material axial flow fan impeller. Background technique [0002] High-strength carbon fiber composite materials are widely used in aerospace, aircraft, impeller and other structures due to their light weight, high strength, designable material properties, and easy processing. Carbon fiber and its composite products are currently the fastest growing in the world. One of the high-tech materials. With the decline of carbon fiber prices and the increase of production, carbon fiber composite materials have gradually entered the civilian market, such as wind turbine impellers, compressor impellers, various propeller impellers, etc. More and more carbon fiber composite materials are used, and carbon fiber There are not many studies on the impeller of axial fans. [0003] There are many studies on carbon fiber composite impellers at home and abroad. For example, Yan...
