In a replacement is implemented, Fig. 5 (b) is referred to, the by-pass structure 300 is formed on second connector 240,
And be arranged at the second flow channel 210 and extend towards the 4th port 214, the by-pass structure 300 and the second framework 200 and this
Two connectors 240 define the bypass flow channel 301 jointly.When first fan 10（Include first stator 170 and the first rotor
190）And second fan 20（Include second stator 280 and second rotor 290）Start after rotation, in first framework
The outer gas stream a and the outer gas stream b of surrounding in 100 center of the first port 111（Refering to Fig. 6 (b)）Can be because the first rotor
190 rotation and from first port 111 be inhaled into the first flow 110 formation mixed airflow c, into the first flow 110
Mixed airflow c can flow into the second flow channel 210 of second framework 200 because of the rotation of second rotor 290, an and part
Mixed airflow c can be because the push of the first rotor 190 enters the bypass flow channel 301 formation bypass flow d, the mixed airflow c
And bypass flow d is all discharged from the 4th port 214.
Referring to Fig. 7, the profile of the second embodiment for fan of the present invention with by-pass structure, and be aided with refering to figure
5, as illustrated, the present embodiment part-structure and function are identical with aforementioned first embodiment, therefore it will not be described in great detail herein, only this reality
Apply not existing together for the by-pass structure 300 has a S types section, makes the bypass flow channel 301 same for example and aforementioned first embodiment
When also have S types section.
Referring to Fig. 8, real for the part sectioned view and replacement of the 3rd embodiment of fan of the present invention with by-pass structure
Part sectioned view is applied, and is aided with refering to Fig. 5, as illustrated, the present embodiment part-structure and function and aforementioned first embodiment phase
Together, therefore it will not be described in great detail herein, only the present embodiment and aforementioned first embodiment do not exist together for the by-pass structure 300 defines this
Bypass flow channel 301 be a tapered runner, for example the by-pass structure 300 and be arranged at the first flow 110 extend towards this first
During port 111, the bypass flow channel 301 is tapered from first port 111 to second port 113；Or the by-pass structure 300 is set
When the second flow channel 210 extends towards four ports 214, the bypass flow channel 301 is from the third connectivity mouth 212 to the four-way
Mouth 214 is tapered.Due to the tapered runner be upstream cross section it is larger, cross-section downstream is smaller, by air-flow be produce faster
The flow velocity of speed.
Referring to Fig. 9, the profile of the fourth embodiment for fan of the present invention with by-pass structure, and be aided with refering to figure
5, as illustrated, the present embodiment part-structure and function are identical with aforementioned first embodiment, therefore it will not be described in great detail herein, only this reality
Apply not existing together for the by-pass structure 300 defines the bypass flow channel 301 for a flaring runner, example for example and aforementioned first embodiment
Such as by-pass structure 300 and when being arranged at the first flow 110 and extending towards first port 111, the bypass flow channel 301 is by this
First port 111 is to the flaring of the second port 113；Or the by-pass structure 300 be arranged at the second flow channel 210 extend towards this
During four ports 214, the bypass flow channel 301 is from the third connectivity mouth 212 to the flaring of the 4th port 214.Make first port 111 weeks
The outer gas stream enclosed is inhaled into after the bypass flow channel 301, due to the flaring runner be upstream cross section it is smaller, cross-section downstream compared with
Greatly, the promotion of air-flow really, just can be discharged to the outside by the effect with supercharging of slowing down.
Thereby, through the design of by-pass structure 300, do not increasing fan dimension and do not increasing the situation that fan consumes power
Under, it can effectively reach the effect for improving fan air output.
The present invention is described in detail above, only described above, only the preferred embodiments of the invention, when not
The scope of implementation of the invention can be limited.I.e. all equivalent changes and modifications made according to the present patent application scope etc., all should still belong to this
The patent covering scope of invention.
