The partial schematic diagram of the axial flow fan central hub enlarged scale of the described electronic cooling fan of Fig. 2 special exhibition; And
Fig. 3 is the partial sectional view of III-III along the line in Fig. 2.
Embodiment
In accompanying drawing, an electronic cooling fan of the present invention is overall to be represented by 1.
Known described electronic cooling fan 1 comprises supporting structure or the cowl 2 that is in fact tabular, and described supporting structure or cowl 2 have main circular hole 3, axial flow fan (overall by 4 expressions) and be rotatably installed in described main circular hole 3.
Described axial flow fan 4 is connected to the rotor of a motor, and described motor is invisible in Fig. 1, Fig. 2, but part is visible in figure 3, overall by 5 expressions.
Described motor 5 comprises a stator 6, on supporting structure as described in described stator 6 is fixed on by a known mode (as relied on the several spokes represented by 7 in Fig. 1) or cowl 2.
Described motor 5 also comprises a rotor, and described rotor comprises the top represented by 8 in a Fig. 3.
Described axial flow fan 4 comprises a central hub 9, and several blade 10 extends out from described central hub 9, and the outermost end of described several blade 10 is connected to one week side ring 11 (as shown in Figure 1).
The central hub 9 of described axial flow fan 4 is connected to the rotor 8 of described motor 5 by one or more tie point or connection area.
In the embodiment shown in the figures, described central hub 9 is connected to the rotor top 8 of described motor 5 in three tie points or connection area (representing by 12), and described tie point or connection area 12 are located at the identical distance d place (as shown in Figure 3) of axis X-X apart from described axial flow fan.
In the embodiment shown, the central hub 9 of described axial flow fan 4 has one substantially in bowl-shape profile, and an end wall 9a is connected to one and is at least roughly columniform annular sidewall 9b.
The rotor top 8 of described motor 5 stretches into the end wall 9a of inner, the close described central hub 9 of described central hub 9, described top 8 is connected to described central hub 9 by the connecting element 13 comprising respective elastic suspension in aforementioned three tie points or connection area 12, and described connecting element 13 will be described more fully below.
Special in Fig. 3, each connecting element 13 comprises one by elastic material, especially the cyclic spring vibration damper 14 made of highly resilient material (vulcanized rubber).
Described elastic suspension 14 is located in a through hole 9c of described axial flow fan central hub 9 end wall 9a.
