Example Embodiment
[0033] Example 1:
[0034] refer to Figure 1-4 A compact centrifuge fan includes a volute 10, a drive device 20, and an impeller 30, and the drive device 20 is connected to the volute 10 and the impeller 30, respectively, and the impeller 30 is rotatably mounted within the volute 10.
[0035] The volute 10 includes a front end cover 11, a rear end cover 13, a side panel 12, and a worm 16, and the side plate 12 is fixed to the front end cover 11 and the rear end cover 13, respectively, the air outlet 14 is disposed on the front end cover 11, impeller 30 is located between the front end cover 11 and the rear end cap 13. The anti-vorter 40 is fixed to the front end cover 11. The front end cover 11 is fixedly connected to a guide plate 17 located between the anti-vorter 40 and the air outlet 14, and the guide plate 17 is bent toward the impeller 30. The worm 16 is fixed to the side panel 12 and the air outlet 15 side wall, and there is a venting groove 42 between the anti-vontaminatio...
Example Embodiment
[0067] Example 2:
[0068] refer to Image 6 A compact centrifugal fan, the difference from the embodiment is that the anti-vorter 40 is consistently surrounded by an annular shape outside the impeller 30.
[0069] This embodiment has the following advantages:
[0070] The anti-vorter 40 is arranged to be monolithically surrounded by an annular shape surrounded by the outer circumference of the impeller 30, so that the anti-vorter 40 can better interfere with the formation of the axial secondary stream, and can effectively reduce the intensity of the axial secondary stream, thereby It is possible to improve the state of the flow of the volute of the volute 10, and the effective flow of the volute flow inside the volute 10 is improved.
