Description
Technical field
The invention belongs to fan technology field, particularly relate to a kind of 360 ° of fans of noise reduction.
Background technology
Conventional fan often outward appearance is general, does not possess the most noticeable characteristic, also goes up ten at air-out direction
Point single, often can only blow a direction, it is impossible to ensure 360 ° can air-out.Or need fan not
Wave with stopping so that there is wind in each direction, but cannot ensure that synchronization is respectively provided with and blow air over.
For solving the problems referred to above, occurring 360 ° of fans the most on the market, it not only possesses modernization fan
Performance, has again the outward appearance of Greco-Roman Style simultaneously.Fan merges classic and modern feature.It is not only a fan,
Or an art work.There is metal net mask outside, plays protective action.When 360 ° of fans achieve same
Carve 360 ° can dry.Putting with on a meeting desk, everyone can blow and obtain wind.
Although current 360 ° of fan noises are the least, but on leaf tops such as axial leaf top and radial direction leaf tops, due to turbine
Cause ambient gas to pulse during rotation, cause air-flow unstable, increase rotational noise and produce probability.
Accordingly, it is considered to above-mentioned situation, it is badly in need of a kind of 360 ° of fan turbine apparatus of design, reduces turbine leaf
While the noise that sheet produces, it is ensured that 360 ° of fan entirety aeroperformances.Additionally also reduce resonance
Generation may.
Summary of the invention
It is an object of the invention to for the deficiencies in the prior art, it is provided that a kind of 360 ° of fans of noise reduction, can
In the case of ensureing 360 ° of fan entirety aeroperformances, reduce the aerodynamic noise that turbo blade produces.
A kind of 360 ° of fans of noise reduction, including motor, rotary shaft, turbine, motor fixing frame, small-sized fans
With netted outer housing；Turbine entirety is wrapped up by netted outer housing, and motor fixing frame is provided with motor, motor defeated
Shaft is connected with turbine by power transmission shaft, and motor, motor fixing frame, rotating shaft are arranged in pedestal；Small-sized
Fan is arranged in pedestal, and is mounted directly and is connected with rotating shaft concentric fit on the rotating shaft, utilizes rotating shaft straight
Tape splicing moves this small-sized fans and rotates.
Described turbine includes six primary blades, six splitterr vanes and flat board, and the camber of blade is flat board half
0.2 times of footpath, thickness is that 4mm, blade and flat board are orthogonal, and primary blades is spaced apart with splitterr vanes,
Primary blades height is consistent with the diameter of flat board, the height of splitterr vanes be primary blades axial height 1/6～
1/4；Pitch compares rate of change less than 12%.
Wherein, the pitch rate of change that compares is that irregular pitch formula adjacent blades circumference angle is adjacent with equal pitch formula
The difference of blade circumference angle and the ratio of equal pitch adjacent blades circumference angle, i.e. if fan has n leaf
Sheet, then wherein the angle between adjacent blades and blade just has n, if arranged according to equal pitch, then
Angle angle is 360 °/n, and the angle between irregular pitch formula adjacent blades and blade is followed successively by
I=1,2 ... n.Then the corresponding pitch rate of change that compares is
Described small-sized fans is single rotor aerofoil fan, birotor aerofoil fan or mixed flow fan.
The present invention has a following good effect: owing to the addition of small-sized fans to add Wind Volume in 360 ° of fans,
Promote air current flow by opening the donut of bottom base and motor fixing frame simultaneously, thus improve
Top turbine air-out volume.Turbine has been changed into the 360 ° of fans of irregular pitch formula into a kind of band splitterr vanes
Turbine, this operation ensures that turbine will not produce resonance, simultaneously because primary blades and the irregular pitch of splitterr vanes
Distribution matches, it is ensured that fan is dynamically balanced the most stable so that it is deviate in pulsation aerodynamic force phase place, fall
Low noise radiation.
