[0033] like Figures 1 to 2As shown, the cooling fan 100 includes: a fan body 10, a wire plate 20, a wire cover 30, a fixing member 40 and a connecting member 50, wherein the fan body 10 is used to install the wire plate 20, the wire plate 20 is used to receive the wire harness of the fan body 10, and guide the wire harness out of the cooling fan 100 from a predetermined direction, the wire cover 30 is used to seal the wire plate 20 to fix the wire harness in the wire plate 20, the fixing member 40 is used to fix and connect the wire plate 20 and the wire cover 30, and the connecting member 50 is used to fix the wire plate 20 on the fan body 10. The wire harness is installed by the wire plate 20, the wire cover 30 closes the wire plate 20, and the wire cover 30 and the wire plate 20 are connected by the fixing member 40. The connecting member 50 fixes the wire plate 20 on the fan body 10, which is conducive to fixing the wire harness of the fan body 10 through the cooperation of the wire plate 20 and the wire cover 30, thereby avoiding collision between the wire harness and the cooling fan 100, thereby effectively reducing the noise generated by the cooling fan 100 during use.

[0034] Below, combined Figures 1 to 4 , the above-mentioned heat dissipation fan 100 is further explained.

[0035] like Figures 1 to 3 As shown, the fan body 10 is provided with a mounting hole 11 and a slot 12 . The mounting hole 11 passes through the fan body 10 for allowing the connector 50 to pass through to fix the fan body 10 . The slot 12 is communicated with the mounting hole 11 for installing the line plate 20 .

[0036] like Figure 2 As shown, the wire board 20 includes a connecting portion 21 and a wire arrangement portion 22. There are two connecting portions 21, and the two connecting portions 21 are spaced apart on both sides of the wire arrangement portion 22. The number of mounting holes 11 and slots 12 corresponds to the number of connecting portions 21. Each connecting portion 21 is respectively embedded in each slot 12. Each connecting portion 21 is provided with a connecting hole 211 corresponding to the position of the mounting hole 11. The wire arrangement portion 22 is provided with a wire inlet 221, a wire outlet 222 and a wire cavity 223. The wire inlet 221 is used to insert the wire harness. The wire inlet 221 and the wire outlet 222 are both connected to the wire cavity 223. The wire outlet 222 is used to lead out the wire harness. There are two wire outlets 222, and the two wire outlets 222 are respectively provided on opposite sides of the wire arrangement portion 22.

[0037] The installation of the wiring harness of the fan body 10 is as follows Figures 2 to 3As shown, the wire plate 20 also includes a wedge 23, which is connected to the connecting portion 21, and the inner wall of the slot 12 is provided with a card slot 13 that cooperates with the wedge 23. Furthermore, the inner wall of the slot 12 is also provided with a guide groove 14, which is connected to the card slot 13 and is used for the wedge 23 to slide. When in use, the wedge 23 of the control wire plate 20 slides into the guide groove 14 and slides into the card slot 13 along the guide groove 14. The wedge 23 is engaged with the card slot 13 to achieve preliminary fixation and positioning of the fan body 10 and the wire plate 20, so that the wiring harness of the fan body 10 enters the wire cavity 223 through the wire inlet 221 and is finally led out from the wire outlet 222.

[0038] like Figures 2 to 4 As shown, the wire cover 30 is in contact with the wire arrangement portion 22 and closes the wire cavity 223. Specifically, the wire cover 30 includes a cover body 31 and a clamping column 32. The cover body 31 closes the wire cavity 223. The clamping column 32 is plugged into the wire plate 20. The wire plate 20 is provided with a limiting column 24 plugged into the clamping column 32. The cooperation between the clamping column 32 and the limiting column 24 facilitates the rapid positioning of the wire cover 30 and the wire plate 20. The fixing member 40 passes through the clamping column 32 and is connected to the limiting column 24 to realize the connection between the wire cover 30 and the wire arrangement portion 22. Further, the wire cover 30 also includes a first wire pressing block 33 and a second wire pressing block 34 connected to the cover body 31. The first wire pressing block 33 closes the wire entry port 221, and is provided with a first wire pressing groove 331, the first wire pressing groove 331 is communicated with the wire cavity 223, and is used to support the wire harness at the wire entry 221 to fix the wire harness at the wire entry 221, thereby effectively preventing the wire harness from shaking at the wire entry 221, and the second wire pressing block 34 closes the wire outlet 222, and is provided with a second wire pressing groove 341. It can be understood that, like the first wire pressing groove 331, the second wire pressing groove 341 is communicated with the wire cavity 223, and is used to support the wire harness at the wire outlet 222 to fix the wire harness at the wire outlet 222, thereby effectively preventing the wire harness from shaking at the wire outlet 222, so as to enhance the fixing effect of the wire harness.

[0039] The heat dissipation fan 100 provided in the present application is used in the following manner: the wedge 23 of the control line board 20 slides into the card slot 13 along the guide groove 14, and the wedge 23 is engaged with the card slot 13, so that the connecting portion 21 is inserted into the slot 12 of the fan body 10, thereby achieving a preliminary connection between the fan body 10 and the line board 20, and the wiring harness of the control fan body 10 enters the line cavity 223 from the line inlet 221 of the line arrangement portion 22 and is discharged from the line outlet 222. Then, the control line cover 30 is abutted against the line arrangement portion 22, so that the card column 32 of the line cover 30 is engaged with the line board 20. The limiting column 24 is plugged in, the first wire pressing block 33 and the second wire pressing block 34 respectively support the wiring harness at the wire inlet 221 and the wire outlet 222 to fix the wiring harness in the wire cavity 223 and prevent the wiring harness from shaking. Finally, the control fixing part 40 is passed through the card column 32 and connected with the limiting column 24 to realize the connection between the wire cover 30 and the wiring part 22, and the control connecting part 50 is passed through the mounting hole 11 of the fan body 10 and the connecting hole 211 of the connecting part 21 to realize the connection between the fan body 10 and the wire plate 20, thereby completing the assembly of the cooling fan 100.
