When the fan motors are actually installed on the first and second bases 130 and 220 and then started, the external air flow at the center of the first port 111 of the first housing 100 is sucked into the first flow channel 110 through the first port 111, the external air flow around the first port 111 is sucked into the bypass flow channel 301 through the first port 111, and the air flows entering the first flow channel 110 and the bypass flow channel 301 flow into the second flow channel 210 of the second housing 200 and are then mixed and discharged from the fourth port 214.

When the fan motors are actually installed on the first and second bases 130 and 220 and then activated, the external air flow at the center and around the first opening 111 of the first housing 100 is sucked into the first flow channel 110 through the first opening 111, and the air flow entering the first flow channel 110 flows into the second flow channel 210 and the bypass flow channel 301 of the second housing 200, passes through the second flow channel 210 and the bypass flow channel 301, and is then discharged through the fourth opening 214.
Referring to fig. 2, a cross-sectional view of a fan frame with a bypass structure according to a second embodiment of the present invention is shown with reference to fig. 1, as shown in the figure, part of the structure and function of the present embodiment are the same as those of the first embodiment, and therefore will not be described herein again, but the present embodiment is different from the first embodiment in that the bypass structure 300 has an S-shaped cross-section, so that the bypass channel 301 also has an S-shaped cross-section.
Referring to fig. 3, which is a cross-sectional view of a fan frame with a bypass structure according to a third embodiment of the present invention, and referring to fig. 1, as shown in the figure, part of the structure and functions of the present embodiment are the same as those of the first embodiment, and therefore will not be described herein again, but the present embodiment is different from the first embodiment in that the bypass structure 300 defines the bypass channel 301 as a tapered channel, for example, when the bypass structure 300 is disposed in the first channel 110 and extends toward the first opening 111, the bypass channel 301 is tapered from the first opening 111 to the second opening 113; or the bypass structure 300 is disposed on the second flow channel 210 extending toward the fourth port 214, the bypass flow channel 301 tapers from the third port 212 to the fourth port 214.

Referring to fig. 4, which is a cross-sectional view of a fan frame with a bypass structure according to a fourth embodiment of the present invention, and referring to fig. 1, as shown in the figure, part of the structure and functions of the present embodiment are the same as those of the first embodiment, and therefore will not be described herein again, but the present embodiment is different from the first embodiment in that the bypass structure 300 defines the bypass flow channel 301 as a divergent flow channel, for example, when the bypass structure 300 is disposed in the first flow channel 110 and extends toward the first opening 111, the bypass flow channel 301 diverges from the first opening 111 to the second opening 113; or when the bypass structure 300 is disposed on the second flow channel 210 and extends toward the fourth port 214, the bypass flow channel 301 gradually expands from the third port 212 to the fourth port 214. After the external airflow around the first port 111 is sucked into the bypass flow channel 301, the divergent flow channel has a smaller upstream cross section and a larger downstream cross section, so that the external airflow can be reliably pushed and discharged to the outside.
Referring to fig. 5, which is a cross-sectional view of a first embodiment of the fan with bypass structure of the present invention, as shown in fig. 5 (a), the fan 2 with bypass structure of the present invention includes a first fan 10, a second fan 20 and a bypass structure 300.

When the first fan 10 (including the first stator 170 and the first rotor 190) and the second fan 20 (including the second stator 280 and the second rotor 290) are rotated, the external air flow a (see fig. 6 (a)) at the center of the first port 111 of the first frame 100 is drawn into the first flow channel 110 from the first port 111 due to the rotation of the first rotor 190, the external air flow b around the first port 111 is drawn into the bypass flow channel 301 from the first port 111, the air flows a and b entering the first flow channel 110 and the bypass flow channel 301 flow into the second flow channel 210 of the second frame 200 due to the rotation of the second rotor 290, and are mixed and discharged from the fourth port 214.

When the first fan 10 (including the first stator 170 and the first rotor 190) and the second fan 20 (including the second stator 280 and the second rotor 290) are started to rotate, the external airflow a at the center of the first opening 111 and the external airflow b around the first opening 111 (see fig. 6 (b)) of the first frame 100 are sucked into the first flow channel 110 from the first opening 111 due to the rotation of the first rotor 190 to form a mixed airflow c, the mixed airflow c entering the first flow channel 110 flows into the second flow channel 210 of the second frame 200 due to the rotation of the second rotor 290, and a part of the mixed airflow c enters the bypass flow channel 301 due to the pushing of the first rotor 190 to form a bypass airflow d, wherein the mixed airflow c and the bypass airflow d are both discharged from the fourth opening 214.
Referring to fig. 7, which is a cross-sectional view of a fan with a bypass structure according to a second embodiment of the present invention, and with reference to fig. 5, as shown in the figure, part of the structure and function of the present embodiment are the same as those of the first embodiment, and therefore will not be described herein again, but the difference between the present embodiment and the first embodiment is that the bypass structure 300 has an S-shaped cross section, so that the bypass flow channel 301 also has an S-shaped cross section.
Please refer to fig. 8, which is a partial cross-sectional view and an alternative partial cross-sectional view of a third embodiment of the fan with a bypass structure of the present invention, and refer to fig. 5, as shown in the drawings, a portion of the structure and the function of the present embodiment are the same as those of the first embodiment, and therefore will not be described herein again, but the difference between the present embodiment and the first embodiment is that the bypass structure 300 defines the bypass channel 301 as a tapered channel, for example, when the bypass structure 300 is disposed on the first channel 110 and extends toward the first opening 111, the bypass channel 301 tapers from the first opening 111 to the second opening 113; or the bypass structure 300 is disposed on the second flow channel 210 extending toward the fourth port 214, the bypass flow channel 301 tapers from the third port 212 to the fourth port 214. Because the upstream cross section of the tapered flow passage is larger, and the downstream cross section is smaller, the passing gas flow generates a faster flow speed.
Please refer to fig. 9, which is a cross-sectional view of a fourth embodiment of the fan with a bypass structure of the present invention with reference to fig. 5, as shown in the figure, part of the structure and functions of the present embodiment are the same as those of the first embodiment, and therefore will not be described herein again, but the difference between the present embodiment and the first embodiment is that the bypass structure 300 defines the bypass channel 301 as a divergent channel, for example, when the bypass structure 300 is disposed in the first channel 110 and extends toward the first opening 111, the bypass channel 301 diverges from the first opening 111 to the second opening 113; or when the bypass structure 300 is disposed on the second flow channel 210 and extends toward the fourth port 214, the bypass flow channel 301 gradually expands from the third port 212 to the fourth port 214. After the external airflow around the first port 111 is sucked into the bypass flow channel 301, the divergent flow channel has a smaller upstream cross section and a larger downstream cross section, so that the external airflow can be reliably pushed and discharged to the outside.
Therefore, through the design of the bypass structure 300, the effect of increasing the air output of the fan can be effectively achieved without increasing the size of the fan and the power consumption of the fan.
