Description
Technical field
The present invention relates to a kind of fan cascaded structure is improved, more particularly to one kind can be greatly reduced fan vibration and reduce and make an uproar
The fan cascaded structure improvement of sound.
Background technology
With the continuous progress of science and technology, people are consequently increased for the dependency of various electronic equipments；However, in running
When, the internal element of electronic product (such as computer, mobile computer) can produce high heat, if cannot lead heat in time
Go out outside electronic product, then easily produce overheated problem, therefore most electronic product allows electronics often using a fan in which
Product is able to maintain that and operates under certain operating temperature range.
1A, 1B figure is referred to, current its fan frame 10 of industry prior art tandem fan 1 is all that same size is constituted,
And the fan frame 10 forms fan with assembling parts such as impeller 11, motor (not shown)s.When the fan is operating, motor torque
The design principle of operating itself will necessarily produce vibration, particularly tandem fan, the structure of prior art tandem fan, and which only leads to
The buckle structure 12 that crosses between fan frame 10 and fan frame 10 is in series, and this series system causes nothing due to combining along fan center's axle
Method changes vibrational state, the impeller 11 inside two fan frames 10 simultaneously rotational run when, the bobbing machine frequency interaction shadow of two impellers 11
Under sound, two fan frames 10 can be caused to produce serious resonance effect, and the vibration that this resonance effect is produced can be direct by fan frame 10
Outside is delivered to, the hard disk in electronic product host computer system is very sensitive for vibrating, and the single composition because of traditional design
The fan frame 10 of part, leads to not effectively reduce vibration, even more serious if, motor can be disturbed with the vibration produced by impeller 11
The normal work of other electronic components, causes system play best efficiency, and, also supervene while resonance effect
Huge noise.
The above, prior art has the disadvantage that：
1. the vibration of fan effectively cannot be reduced；
