Specific embodiment
Fig. 4 is the schematic diagram of blower module.Fig. 5 is that the blower module of Fig. 4 is applied to the schematic diagram in electronic device.Please
With reference to Fig. 4 and Fig. 5, electronic device 200 includes body 210 and the blower module 220 being installed in body 210.Electronics
Device 200 is, for example, laptop.Blower module 220 includes blower-casting 222, fan 224 and radiating subassembly 226.Wind
Fan case body 222 has the open sides 222a and closed side 222b around open sides 222a, and wherein open sides 222a is provided with the
One air-flow guiding channel 2221.Fan 224 is arranged in blower-casting 222, and radiating subassembly 226 is set to open sides 222a,
And radiating subassembly 226 has the second air-flow guiding channel 2261 connecting with the first air-flow guiding channel 2221, and by fan 224
The first air-flow guiding channel 2221 of caused distinguished and admirable process and the second air-flow guiding channel 2261 are released with dust discharge.
Specifically, blower-casting 222 has abutment wall 222c and guiding wall 222d, wherein abutment wall 222c and guiding wall
222d the first air-flow guiding channel 2221 of formation, and the second air-flow guiding channel being connect with the first air-flow guiding channel 2221
2261 are using the radiating subassembly 226 of cut-out to be formed.In addition, radiating subassembly 226 include heat sink body 2262 and
Radiating fin 2263, radiating fin 2263 are set to heat sink body 2262 close to fan 224 by nearside 2262a and far from wind
The separate side 2262b of fan 224.The radiating fin 2263 for being located remotely from side 2262b has from the length outstanding of heat sink body 2262,
And being shorter in length than for radiating fin 2263 for being located at the exit at the second air-flow guiding channel 2261 is located remotely from side 2262b's
The length of remaining radiating fin 2263, to form a back-off region A, and body 210 has heat dissipation outlet 212, and back-off region A is corresponding
In heat dissipation outlet 212.
For enhancing radiating efficiency, radiating subassembly 226 can further include the heat pipe 228 being set in heat sink body 2262.
When electronic device 200 is run, in order to enable the heat of the heat generating component inside electronic device 200 effectively to dissipate
It goes out, therefore blower module 220 operates.In detail, when fan 224 rotates forward, blower module 220 provides heat sinking function.Fig. 6 is
The runner schematic diagram in the dust discharge path of the blower module 220 of Fig. 4.Referring to FIG. 6, subsidiary one mentions, the first air-flow guiding channel
2221 in entire 220 area Zhong Ruofeng of blower module, and fan 224 rotate forward when, dust by wind drive and pass through first
Air-flow guiding channel 2221 and accumulate at the second air-flow guiding channel 2261, therefore position is in the second gas of radiating subassembly 226
Stream guiding channel 2261 can provide the function of the dust chamber 113 of blower module 220 as is known.
It needs to grow structure outstanding as dust chamber in blower-casting 110 compared to known blower module 100
113, there is no the structures outstanding additionally grown for the blower-casting 222 of the blower module 220 of the present embodiment, but utilize skilful
Think, in forming channel architecture on radiating subassembly 226, the second air-flow guiding channel 2261 is made to can be used as one of dust discharge path
Point, it is also capable of providing the function of dust chamber simultaneously.
In addition, because will not influence the stream of wind there is no aperture is arranged on the abutment wall 222c of blower-casting 222
It is dynamic.
And when inverting fan 224, blower module 220 is dusted.
Fig. 7 A is the stereoscopic schematic diagram in the dust discharge path of blower module, and Fig. 7 B is the top view of Fig. 7 A.It please also refer to
Fig. 7 A and Fig. 7 B is distinguished and admirable caused by fan 224 to pass through the first air-flow guiding channel 2221 and the second gas when fan 224 inverts
It flows guiding channel 2261 and is released from the outlet of the second air-flow guiding channel 2261.Specifically, by being located remotely from side 2262b
And the radiating fin 2263 in the exit at the second air-flow guiding channel 2261 is shorter in length than its for being located remotely from side 2262b
The design of the length of remaining radiating fin 2263, so that the windage at this is smaller, therefore by the second air-flow guiding channel 2261
Wind the dust accumulation accumulated on the second air-flow guiding channel 2261 can be discharged, and dust is being radiated out using natural gravity by position
Back-off region A in 212 ranges of mouth is fallen to except the body 210 of electronic device 200.This heat dissipation outlet 212 is that setting exists originally
The holes for corresponding to blower module 220 on body 210, does not need the other holes on body 210, reduces the broken of body 210
The quantity in hole.
In conclusion blower module of the invention and being had at least the following advantages using the electronic device of this blower module:
One, do not influence blower-casting external form and blower module performance in the case where, set inside blower-casting
The first air-flow guiding channel is set, and the second air-flow pilot channel being connected with the first air-flow guiding channel is made in radiating subassembly
On, this second air-flow guiding channel can serve as dust chamber when fan rotates forward because being in the area Ruo Feng；And
When fan inverts, air-flow can be guided and flowed through and wherein released.
Two, position is shorter in length than by the radiating fin for being located remotely from side and the exit at the second air-flow guiding channel
In the design of the length of remaining radiating fin far from side, so that the windage at this is smaller, in addition the pressure air-flow that fan causes,
Therefore the dust accumulation accumulated on the second air-flow guiding channel can be forced to be discharged by the wind of the second air-flow guiding channel, it can be true
Dust is protected to be discharged completely except the body of electronic device.
Three, dust falls to the machine of electronic device in back-off region in the range of outlet of radiating by position using natural gravity
Dust discharge path is other than dust falls to the body of electronic device using natural gravity except body.
Four, the blower-casting of blower module not in addition aperture or setting dust cavity on abutment wall, but in fan hub
The guiding channel that wind can be released is set in vivo and at radiating subassembly, keeps the design of the shape and size of blower-casting excellent
Change, and then the intracorporal other assemblies of the machine for being set to electronic device is allowed to have more elastic ornament space.
Although the present invention is disclosed as above with embodiment, however, it is not to limit the invention, any technical field
Middle those of ordinary skill, it is without departing from the spirit and scope of the present invention, therefore of the invention when can make a little change and retouching
Protection scope is subject to view appended claims confining spectrum.
