[0048] The detailed description and technical contents of the present application are described below in conjunction with the accompanying drawings, however the accompanying drawings are provided for reference and illustration only, and are not intended to limit the present application.

[0049] The present application provides a combined heat dissipation fan, such as Figure 1 and Figure 2As shown, any number of fan units 1 can be combined with each other into a row to form a fan wall (not shown) that can provide better heat dissipation performance.

[0050] As shown, the combined heat dissipation fan (hereinafter referred to as heat dissipation fan) of the present application comprises at least two fan units 1 and at least two insulation assemblies 3, and preferably comprises a plurality of insulation covers 5. The present application does not limit the number of fan units 1, which can be two (not shown in the figure) or more than three as shown in the figure. In this embodiment, two fan units 1 are taken as an example for the purpose of simplifying the description. Therefore, the number of insulation assemblies 3 is two, and the number of insulation covers 5 is four. Figures 1 to 4 The fan unit 1 comprises a fan frame 1a and a fan wheel 1b, which is arranged in the fan frame 1a and can rotate relative to the fan frame 1a. The fan frame 1a has a plurality of sides, including a first side 101 and a second side 102 opposite to each other, and a plurality of other sides (not shown) opposite to each other.

[0051] Each fan unit 1 is adjacent to each other with the other sides and adjacent to each other in a row, so that the first side 101 and the second side 102 of each fan unit 1 are respectively directed to opposite directions. Each first side 101 is provided with a first combination part 11 and a second combination part 12 symmetrical to each other, and each second side 102 is also provided with a first combination part 11 and a second combination part 12 symmetrical to each other.

[0052] The first combination part 11 comprises a first notch S1, a column C and a hole assembly H arranged at a position corresponding to the first notch S1. The second combination part 12 comprises a second notch S2, a column C and a hole assembly H arranged at a position corresponding to the second notch S2.

[0053] In detail, each first notch S1 and each second notch S2 can be formed at the four corners of the fan frame 1a, but not limited thereto, and the recess direction of the first notch S1 and the second notch S2 is recessed from the two sides of the fan frame 1a to the direction of the axis of the fan wheel 1b (not shown in the figure). Each column C can be erected at the four corners of the fan frame 1a (but not limited thereto) in the first notch S1 or the second notch S2 and parallel to the axis of the fan wheel 1b. The hole assembly H comprises at least two holes H1, which can be arranged at opposite positions in the first notch S1 or the second notch S2, but not limited thereto.

[0054]

[0055] ​The insulation assembly 3 is used to combine two adjacent fan units 1. The insulation assembly 3 is entirely made of insulation material, and has a cover plate 31 and two recesses 32 and two buckle assemblies 33 connected to the inner surface of the cover plate 31. The recesses 32 correspond to the columns C, and the buckle assemblies 33 correspond to the hole assemblies H. The cover plate 31 fits into the complete gap (not shown) formed by the first gap S1 and the second gap S2.

[0056] In detail, the two recesses 32 are symmetrical to each other, and the two buckle assemblies 33 are symmetrical to each other. The recesses 32 are recessed to correspond to the columns C, so that the recesses 32 fit into the columns C. As shown in Figure 5 each buckle assembly 33 comprises at least two buckles 331, which are in the shape of hooks and formed at one end of a spring arm 332, and the other end of the spring arm 332 is connected to the inner surface of the cover plate 31. Each buckle 331 corresponds to a hole H1.

[0057] As shown in Figures 3 to 5 to combine two fan units 1, the following first describes the first side 101: as long as the insulation assembly 3 is bridged between the first combination part 11 of one fan unit 1 and the second combination part 12 of the other fan unit 1, the two fan units 1 can be combined with each other at the first side 101. As for the second side 102, as long as another insulation assembly 3 is bridged in the same way, the two fan units 1 can be combined with each other at the second side 102.

[0058] In detail, the recesses 32 of the insulation assembly 3 are inserted into the columns C to produce a positioning effect, and the recesses 32 firmly hold the columns C, so that the two fan units 1 cannot be separated from each other. The buckles 331 of the insulation assembly 3 are buckled into the holes H1 in a reverse manner to produce a firm fixing effect, so that the insulation assembly 3 is not easily pulled out in the reverse direction. The cover plate 31 of the insulation assembly 3 is inserted into the aforementioned complete gap (formed by the first gap S1 and the second gap S2) to cover it, that is, the first gap S1 and the second gap S2 are covered by the cover plate 31, and the cover plate 31 covers the first gap S1 and the second gap S2 in an inserted manner, so that the cover plate 31 is flush with the first side 101 or the second side 102 as shown in Figure 1 and Figure 4 without affecting the appearance of the fan units 1.

[0059] Therefore, the present application can firmly combine any two adjacent fan units 1 with each other, and thus form the aforementioned fan wall which can provide better heat dissipation performance as shown in Figure 1

[0060] As shown in Figures 1 to 4 ​As shown, the insulating assembly 3 preferably also has a protrusion 34 and two wall plates 35, and the protrusion 34 and the two wall plates 35 are also connected to the inner surface of the cover plate 31. The protrusion 34 of the insulating assembly 3 is connected between two recesses 32, allowing the protrusion 34 to... Figure 4 As shown, it is adaptively embedded between the columns C of the two fan units 1; as Figure 3 and Figure 4 As shown, each recess 32 is located between the two sides of each wall panel 35 and the protrusion 34, so that each column C, after being embedded in each recess 32, can... Figure 4 The corresponding structures are located between the two sides of each wall panel 35 and the protrusion 34. Therefore, the insulating assembly 3, through the protrusion 34 and the two wall panels 35, makes the aforementioned connection more secure and completely free of any gaps that could allow for loosening.

[0061] In addition, such as Figures 1 to 5 As shown, in order to cover and beautify the first notch S1 and the second notch S2 on the cooling fan that are not used by the aforementioned insulating assembly 3, this application also includes a plurality of insulating cover members 5.

[0062] The insulating cover 5 is used to cover the remaining first notch S1 and second notch S2 on the first side 101 or the second side 102. The insulating cover 5 is also made entirely of insulating material, and includes a cover plate 51 and recesses 52 and snap-fit ​​assemblies 53 connected to the inner surface of the cover plate 51. Specifically, the insulating cover 5 is approximately half of the insulating assembly 3. Therefore, the recesses 52 of the insulating cover 5 are the same as the recesses 32 of the insulating assembly 3, and the snap-fit ​​assemblies 53 of the insulating cover 5 are the same as the snap-fit ​​assemblies 33 of the insulating assembly 3, and also have two snap bodies 531. The only difference is that the cover plate 51 is different from the cover plate 31.

[0063] Therefore, when the insulating cover 5 is assembled with the first assembly part 11 or the second assembly part 12, the recess 52 of the insulating cover 5 can also be inserted into the corresponding column C, and each buckle 531 of the insulating cover 5 can also be snapped into each buckle hole H1. As for the cover plate 51, it is inserted into the first notch S1 or the second notch S2 to cover.

[0064] The insulating cover 5 also includes a wall panel 55 connected to the inner surface of the cover 51, and the wall panel 55 is the same as the wall panel 35 of the insulating assembly 3, and therefore has the same effect as the wall panel 35; the insulating cover 5 also includes a side wall 54 connected to the cover 51, and the side wall 54 is approximately equivalent to half of the aforementioned protrusion 34, and therefore has the same effect as the protrusion 34.

[0065] It should be noted that since both the insulating assembly 3 and the insulating cover 5 are made entirely of insulating material, they are not related to electrical conduction or electrical control, and are simply used as an assembly.

[0066] The above descriptions are only the relatively best working examples of the present application, and are not intended to limit the patent scope of the present application. Any equivalent structural changes made according to the contents of the present application and the drawings are intended to be included in the patent scope of the present application.
