Abstract
The invention relates to a cooling fan which comprises a cylindrical hub (2) and a plurality of rotating fan blades (3). The cylindrical hub is combined with a driving shaft of a driving motor, the rotating fan blades are arranged on the peripheral surface of the hub (2) in a radial manner and connected with the hub (2), and a wind shielding ring (1) is arranged outside the radial fan blades (3) and used for improving rotating rigidity and reducing deformation. The cooling fan is characterized in that the fan blades at the combined positions between all fan blades (3) and the outer peripheral surface of the hub (2) are asymmetrically distributed in a variable-angle manner, the effect of generating low noise and large flow is achieved, and the NVH performance is improved on the base of guaranteeing large flow.
Description
Technical field
The present invention relates to a kind of automobile engine cooling fan, especially a kind of varied angle quiet motor cooling fan.
Background technique
Motor car engine noise can cause being weary of of driver and fatigue, thus has influence on driving safety; The intensity of noise is larger, frequency is higher, to the health of people and work influence larger, also darker to the heart injury of people, unnecessary worry and pressure is caused to people, people are created automobile and detests sense, reduce the important topic that the technical research of motor car engine noise technique is automotive technology development always.The deficiency that present engine cooling fan exists, the aeroperformance of blade and acoustics index are a pair contradiction that can not reconcile, and how effectively to solve, and it is also proposed new requirement to cooling fan for cars.
Summary of the invention
The present invention proposes to solve the large problem of the little noise of above-mentioned flow, and its object is to provide a kind of varied angle cooling fan, varied angle low noise cooling fan comprises: protect solar or lunar halo, wheel hub, flabellum, inserts and radial floor.Described drum wheel hub, is coordinated with drive motor live axle by inserts; Described multiple rotary fan, hub periphery face radially arranges and is connected with wheel hub; Described cooling fan flabellum and described wheel hub are connected in not equal angles, afterbody not easily causes the separation of flow, it is characterized in that, external lateral portion or the air flow amount of inboard portion effect all fully can be obtained, the existing cooling fan producing the air flowing of identical amount is compared, and noise is also lower than existing fan; Described flabellum and described wheel hub are connected in not equal angles, for reducing the separation of flow, concrete angular dimension by CFD flow field noise analysis formulation, and by pneumatic noise testing to angle modification.Described protects solar or lunar halo for connecting all flabellum outer ends, improves rotational stiffness, reduces distortion; And described solar or lunar halo section configuration of protecting is L-type, protects solar or lunar halo for raising and bend and torsional stiffness; Described drum wheel hub is hollow shell structure, and for reducing fan turns inertia, rotational stiffness is improved by radial rib structure in hollow side.

Embodiment:
Below in conjunction with accompanying drawing, the present invention is being described.
Shown in Fig. 1 and Fig. 4, large discharge quiet motor cooling fan, comprises, protects solar or lunar halo (1), cylindric wheel hub (2), flabellum (3), inserts (4) and radial floor (5).
Wherein drum wheel hub (2), is coordinated with drive motor live axle by inserts (4); Multiple rotary fan (3), radially arrangement being connected in not equal angles with wheel hub (2) on described wheel hub (2) outer circumferential face; Solar or lunar halo (1) is protected in radial fan (2) outer ring, for improving rotational stiffness, reduces distortion.
Shown in Fig. 1 and Fig. 2, described flabellum (3) and described wheel hub (2) are connected in not equal angles, for reducing the separation of flow, concrete angular dimension by CFD flow field noise analysis formulation, and by pneumatic noise testing to angle modification.
Shown in Figure 3, wherein protecting solar or lunar halo (1) for connecting all flabellums (3) outer end, improving rotational stiffness, reduce distortion; And described solar or lunar halo section configuration of protecting is L-type, protects solar or lunar halo (1) for raising and bend and torsional stiffness.
Shown in Figure 4, wherein drum wheel hub (2) is hollow shell structure, and for reducing fan turns inertia, rotational stiffness is improved by radial rib structure (5) in hollow side.
Cooling fan flabellum (3) of the present invention and described wheel hub (2) are connected in not equal angles, and afterbody not easily causes the separation of flow, therefore, it is possible to obtain external lateral portion or all sufficient effect of the air flow amount of inboard portion.In addition, compared with the existing cooling fan flowed with the air producing identical amount, noise is also lower than existing fan.
