Admission space is formed between assist side and mounting base 112, for wiring board cooling.
Preferably, as shown in figure 13, the edge of the composition air inlet of mounting base 112 is arc structure, the composition of cylinder into
Air port top edge is also arc structure, so that air-flow can smoothly enter blower 100, cooling to device realizing
While, reduce noise.
In Figure 13, in a preferred embodiment of the present invention, mounting hole is medially provided in mounting base 112
1121, when assembling the blower 100 of the application, the second bearing seat 123 of blower skeleton 120 is engaged with mounting hole 1121.Into one
Step ground, is provided with alignment bumps 1122 (Figure 13), including alignment bumps 1122 on the inner sidewall of the mounting hole 1121 of shell 110
The alignment indentation 1231 for being positioned to open up on 123 circumference of second bearing seat with blower skeleton 120 on side wall engages, thus
Shell 110 can be limited to rotate relative to blower skeleton 120 around rotation axis.Enable air inlet and blower 100
Internal stator module 130 is aligned, to further increase cooling effect.
It is provided with protrusion 114 along the circumferential direction in the not set mounting rail of the shell 110 and one end of mounting base, therewith
Accordingly, groove 1212 (Fig. 7) is circumferentially provided in the lower part of the impeller chimney 121 of blower skeleton 120.In assembly blower
When 100, the further positioning of shell 110 and blower skeleton 120 is realized by the way that protrusion 114 to be inserted into groove 1212.Also
It is to say, it, can be more square by the engagement of protrusion 114 and groove 1212 and the engagement of alignment bumps 1114 and alignment indentation 1231
Just the positioning assembly of shell 110 and blower skeleton 120 is realized.
When positioning assembly, for the working performance for guaranteeing blower 100, parts thereof has seal request when installing.Such as this
After shell 110 and blower skeleton 120 in text are installed, it is ensured that air stream can not flow out from there.It can be preparatory in groove 1212
Quantitative adhesive is added, when protrusion 114 is pushed into, adhesive will be overflowed along the inner and outer wall of protrusion 114, in this way, inner wall
Place and outer wall will form complete seal film, achieve the effect that double-layer seal.
The inlet air flow path of the embodiment of the present invention is discussed in detail next, with reference to Figure 14 and Figure 15.
In Figure 14, fraction enters inside blower 100 on the outside of air inlet 1111 of the invention, in axial direction passes through
It crosses at the skeleton wind-guiding face 1211 for the inside that stator module 130 reaches impeller chimney 121, the skeleton wind-guiding face 1211 is at least by two sections
Subarc face forms (as shown in figure 15), to form smooth air stream path of navigation.The skeleton wind-guiding face 1211 has air
Aerodynamic shape is effectively reduced windage and reduces the turbulent flow in blower and noise.
On the other hand, fraction enters inside blower 100 from air inlet of the invention, by balance ring, permanent magnet
142, stator module 140 are finally discharged from one end of the close impeller of fitting opening 125.Due to this part wind will pass through it is several
All heat-generating components, can be with the most heat in walking fan 100.And as described above, in the preferred of this paper
In embodiment, reinforcing rib 128 is positioned as axially aligning with side rib, the thickness h of the reinforcing rib 1281Less than or equal to the thickness of side rib
Spend h2, this makes the air-flow windage from discharge minimum, to reduce the turbulent flow and noise in blower.
Compared with the radiating mode that aperture is arranged on shell in the prior art, shell has multi-way air-inlet mouth, and air inlet makes
It obtains the wind after entering shell and blows to stator module along substantially rectilinear direction, blow to rotor assembly and blower bone in a substantially radial direction
Frame further enhances cooling effect, promotes fan performance and service life；The edge of air inlet is at least by one section of arc surface structure
At making air-flow smoothly enter blower, drop low wind noise.
In the description of the present invention, it is to be understood that, term " on ", "lower", "bottom", "top", "front", "rear", "inner",
The orientation or positional relationship of the instructions such as "outside", "left", "right" is to be based on the orientation or positional relationship shown in the drawings, merely to just
In description the present invention and simplify description, rather than the device or element of indication or suggestion meaning must have a particular orientation, with
Specific orientation construction and operation, therefore be not considered as limiting the invention.
Although describing the present invention herein with reference to specific embodiment, it should be understood that, these realities
Apply the example that example is only principles and applications.It should therefore be understood that can be carried out to exemplary embodiment
Many modifications, and can be designed that other arrangements, without departing from spirit and model of the invention defined by claim
It encloses.It should be understood that different appurtenances can be combined to want by being different from mode described in original claim
It sums feature described herein.It will also be appreciated that the feature in conjunction with described in separate embodiments can be used at other
In the embodiment.
