Fig. 2 is partial sectional view of the fan apparatus shown in Fig. 1 along line II-II；
Fig. 3 is the partial enlarged view of Fig. 2, it is shown that the section of pad and corresponding clamping part.
Embodiment
Below in conjunction with attached drawing, the present invention will be described in detail.
In Fig. 1, reference numeral 1 represents fan apparatus provided by the invention, which can be used for heat exchanger, such as vapour
The radiator of car.
Fan apparatus 1 has the supporting structure or shield 2 generally in tabular.Shield 2 can be made of plastics, and had and opened
Mouth 3.Be open 3 passage as the draft of heat exchanger, which has substantially circular cross section.
Some spokes 4 are inwardly stretched out from the edge of opening 3, and are connected to the circular shaped support 5 of centre.
Preferably, spoke 4 and circular shaped support 5 form an entirety with shield 2.
Fan apparatus 1 further includes electric fan 6, and electric fan 6 is located in opening 3, i.e. installed in the position of opening 3.
Electric fan 6 includes driving motor 7 and is installed to the impeller 8 of motor 7, and impeller 8 has some blades 9.
Blade 9 is distally connected to outer collarette 10.
With reference to figure 1 and Fig. 2, shield 2 has an epitaxy part, for example, it is horizontal on prolong portion 2a.On prolong portion 2a stretch to heat exchanger or
The horizontal cross member 20 of vehicle.After fan apparatus 1 assembles, above prolonging has gap 21 between portion 2a and cross member 20.
Referring to figs. 2 and 3 prolonging 2a flexible liners 12 in portion on shield 2.Preferably, liner 12 is led
To be made of ethylene propylene diene rubber, there is suitable consistency and elasticity.
Pad 12 has a kind of structure, which can close above-mentioned gap 21 when assembling fan apparatus 1（Fig. 2）.
With reference to figure 3, in the present embodiment, prolonging portion 2a on shield 2 has clamping part 14.There is pad 12 fixed part 13 to be used for
Engage with the clamping part 14.
Pad 12 also has the sealing 15 of sealing lip-like, i.e. the section of sealing 15 is in lip.Preferably, sealing
15 form an entirety with fixed part 13, are integral type overall structure.
Between sealing 15 and fixed part 13, there is at least one longitudinal fluting 16, with sealing 15 and fixed part 13
Between formed similar to elastic hinge Hookean region 18.Preferably, the opposite side opposite with groove 16, it may have longitudinal fluting
17, groove 16,17 is used to form the Hookean region 18 similar to elastic hinge, elastic region between sealing 15 and fixed part 13
The thickness in domain 18 is significantly less than the thickness of sealing 15 and fixed part 13, so that sealing 15 can be relatively fixed portion 13 around elastic region
Domain 18 rotates.Preferably, groove 16 and 17 is mutually staggered.
Prolonging the clamping part 14 of portion 2a on shield has the cross section of reversed acanthoid, for example, the upper end as digital " 1 ".Pad 12
Fixed part 13 there is the resettlement section 13a that caves in, the shape of cross section of resettlement section 13a and the shape of cross section of clamping part 14
Match somebody with somebody.
Clamping part 14 can also have some convex blocks 19 crossed out.Pad 12 resettlement section 13a wall on have pair
The hole 13b answered, for being fastened with convex block 19.
Pad 12 can be made of elastic material.Preferably, manufactured by die-casting process.
Pad 12 can be easily installed to clamping part 14, can also go to fix and reliable way by stablizing.
With reference to figure 2, the sealing structure 15 for padding 12 can be used for preventing air-flow by between shield 2 and cross member 20
Gap 21, it is therefore prevented that air-flow is revealed at gap 21, so as to improve overall efficiency.The heat exchange that another embodiment of the present invention provides
Device can also have a cross member 20 with reference to figure 2, the heat exchanger.The epitaxy part of the shield 2 of the fan apparatus of heat exchanger and horizontal stroke
To forming the gap 21 between component 20.As described above, because pad 12 sealing structure 15 prevent air-flow by shield 2 with
Gap 21 between cross member 20, it is therefore prevented that air-flow is revealed at gap 21, so as to improve overall efficiency.
The above, for those of ordinary skill in the art, can be with technique according to the invention scheme and technology
Other various corresponding changes and deformation are made in design, and all these changes and deformation should all belong to the claim of the present invention
Protection domain.
