Novel axial flow fan bearing system

Abstract

The invention discloses a novel axial flow fan bearing system. The novel axial flow fan bearing system comprises a power structure, a shell and blades, the power structure is covered with the shell, the shell is sequentially provided with a wheel shell and a wrapping shell from inside to outside, the blades and the wrapping shell are integrally formed, and the wrapping shell, the wheel shell and the blades are all made of metal materials; and the thickness of each blade ranges from 0.3 mm to 2.5 mm, and the wing section angle of each blade ranges from 30 degrees to 48 degrees. The wrapping shell, the wheel shell and the blades are all made of the metal materials, so that heat generated by the power structure can be well conducted to the blades and then dissipated through air flow, bearing temperature rise can be well reduced, the service life of a fan is prolonged, the rotating speed can be increased on the premise that the bearing temperature rise is met, the cooling performance can be greatly improved, meanwhile, the metal design is adopted, thinner blades and higher strength can be achieved, higher and lower temperature can be resisted, the application range is widened, wind resistance is reduced, and the performance of the fan is improved.

Description

technical field [0001] The invention relates to the technical field of cooling fan structures, in particular to a novel axial flow fan bearing system. Background technique [0002] With the development trend of thinner, thinner and high-performance electronic products, the heat generation of electronic components is also gradually increasing. In order to avoid excessive heat from affecting the product experience, the demand for heat dissipation using thin fan blades is also increasing. [0003] 1. The current design of the axial flow fan blades, the one-piece plastic blades cover the metal wheel shell, the blades run at high speed, the bearing system generates a lot of heat and cannot be released, resulting in high bearing temperature and shortened life. To ensure the life expectancy , the fan speed is limited; the plastic one-piece blade is limited by the material of the plastic itself, it is not easy to make it thinner, and the wind resistance is large, which affects perfo...
