Embodiment 1
Please with reference to Fig. 1, Fig. 2, Fig. 3 and Fig. 4, fan screen 100 includes guard body 10, arc-shaped partition 20.
Guard body 10 is annulus symmetrical structure, and its size is adapted to the impeller size of tube-axial fan.By guard originally
Body 10, fan screen 100 and tube-axial fan are integrated into a whole.Fan screen 100 is by the inside of tube-axial fan with outward
Boundary completely cuts off, and had both protected the person from fan injury, and had avoided fan to be subject to interference and the infringement in the external world again.
, as circumferential spread, multiple arcs dividing plate 20 is along circumferential spread for the circumference with the center of guard body 10 as the center of circle for the definition
It is distributed evenly between profile and the center of guard body 10.Multiple arcs dividing plate 20 one end is connected to the wheel of guard body 10
Exterior feature, the other end is connected to the center of guard body 10, forms space so that gas is discharged between multiple arcs dividing plate 20.Guard is originally
Body 10 can be made up of plastics or metal with arc-shaped partition 20.
The gas flow of tube-axial fan parallel to rotating shaft, i.e. perpendicularly to circumferential spread place plane.Due to axial-flow type
The air quantity dispersion of fan, concentration degree are low, are unfavorable for the raising of radiating efficiency.Research shows, by limiting the row of arc-shaped partition 20
Cloth angle, can act on to the gas applying flowing through fan screen 100, be allowed to produce spiral and gather, thus improving the concentration of gas
Degree.Because gas concentration degree improves, that is, gas volume reduces, and gas potential energy is converted into gas kinetic energy and improves the flowing of gas
Speed.Therefore, improve the exhaust efficiency of fan screen 100, limit the angle position of arc-shaped partition 20 and circumferential spread place plane
In the range of 2～50 °.In this angular range, arc-shaped partition 20 is fairly obvious to the effect of gas, the spiral between gas
Compacting effect reaches most preferably, and gas flow rates are greatly improved.
In order to improve the interaction between arc-shaped partition 20 and gas, arc-shaped partition 20 is cut by circumferential spread place plane
The profile obtaining should be smooth curve.Smooth curve is a curve everywhere having tangent line, and tangent line is continuous with the movement at point of contact
Rotate.When gas enters fan screen 100, because the cross section profile of arc-shaped partition 20 has smooth and continuous, gas edge
Arc-shaped partition acts on and distorts, and spiral compacting effect becomes apparent from.
Defining the surface away from fan on arc-shaped partition 20 is upper surface 22.In order to optimize the road of gas discharge further
Footpath, the shape of upper surface 22 is defined to smooth surface.Called torulopsis curved surface, refers to the curved surface in the incisal plane of continuous variation, or
Person says can be with the curved surface of the unit normal vector of everywhere continuous movement.When gas touches the surface of arc-shaped partition 20, gas is subject to
The effect of arc-shaped partition 20 and along its Surface runoff, present extremely obvious helical effect.Between arc-shaped partition 20
Space limits, and while gas spiral distortion, gas volume compresses and flow velocity improves.
In order to strengthen the structural stability of fan screen 100, it is to avoid fan screen vibrations are impaired or produce noise, guard is originally
The center of body 10 is provided with reinforcement boss 11.Arc-shaped partition 20 one end is connected on reinforcement boss 11, and the other end is connected to net
On the profile of cover body 10, stable structure is integrally formed and avoids compressive deformation.
Define guard body 10 on close to the surface of fan be inner face 12.Inner face 12 is the Main Function discharging gas
Face, directly bears the shock loading of gas.The gas air quantity dispersion being produced due to tube-axial fan, in order to avoid due to distribution not
The concentrfated load all causing, inner face 12 be shaped as plane.In a flat state, the gas effect that inner face 12 is subject to is big
Width reduces, and is effectively prevented the destruction that concentrfated load causes.
Define arc-shaped partition 20 on close to the surface of fan be lower surface 21.Lower surface 21 is to discharge gas to put on arc
The Main Function face of dividing plate 20, directly bears the shock loading of high-speed gas.In order to avoid the collection being caused due to skewness
Middle load, lower surface 21 be shaped as plane.In a flat state, lower surface 21 uniform stressed, is effectively prevented concentrfated load
The destruction causing.
Further, in order to simplify structure and improve bulk strength performance, inner face 12 is coplanar with lower surface 21.In this feelings
Under shape, inner face 12 and lower surface 21 one stand under load, it is to avoid the destruction risk of the stress concentration of connecting portion during antarafacial.
In order to strengthen the strength and stability of fan screen 100 further, the profile of guard body 10 with strengthen boss it
Between be provided with the annulus floor 30 concentric with the profile of guard body 10.Annulus floor 30 is connected with arc-shaped partition 20, to arc
Dividing plate 20 plays the effect of fixing support, strengthens the interaction between each arc-shaped partition 20, prevent fan screen 100 because
Wind speed too fast and lead to deform.
Embodiment 2
Please with reference to Fig. 5, Fig. 6 and Fig. 7, fan screen 100 includes guard body 10, arc-shaped partition 20.
Guard body 10 has square profile profile, but has the inner chamber of circumferential shapes, and the size of inner chamber is adapted to axle
The impeller size of flow fan is it is ensured that enough leaving area.By guard body 10, fan screen 100 and tube-axial fan
It is integrated into a whole, has completely cut off tube-axial fan impeller and extraneous contact, be effectively protected personal safety and impeller
Safety.
Further, guard body 10 is additionally provided with the connecting hole 13 for being connected with tube-axial fan.Connecting hole 13 is equal
The corresponding hole site of tube-axial fan between the even profile being distributed in guard body 10 and circumferential inner wall, can be connected to by screw rod,
