Abstract
The invention discloses a big flow rate low-noise engine cooling fan, which comprises a hub and a plurality of rotating blades, wherein the hub is matched with a driving motor driving shaft through an insert, rotating blades are arranged on the periphery of the hub in a radial shape, an air protection ring which improves rotating rigidity is arranged on an outer ring of the hub, sector gaps are respectively arranged on combined positions of the rotating blades and the hub, and each sector gap is of a trapezoid. Because the sector gaps are arranged on the each rotating blade to contact with the peripheral surfaces of the hub, the big flow rate low-noise engine cooling fan can achieve the effect that no matter the air flow rate in the outer portion or in the inner portion is full. Furthermore, compared with prior cooling fans with the same amount of air flow, the big flow rate low-noise engine cooling fan is also lower than existing fans in noise.
Description
Technical field
The present invention relates to a kind of cooling fan of engine, especially a kind of large discharge quiet motor cooling fan.
Background technique
Along with people are to the raising of car comfort, cost-effectiveness requirement, the energy and environment day by day urgent, cooling fan of engine is had higher requirement: while the cooling capacity of fan requires to improve, also need strictly to control fan noise, in a word, traditional fan structure can not meet the development need of current industry.
No matter any cooling fan, current blade shape shaping structures is simple, fast, but the little noise of flow is large, afterbody easily causes the separation of flow, and this is the deficiency that present engine cooling fan exists, and the aeroperformance of blade and acoustics index are a pair contradiction that can not reconcile, how effectively to solve, new requirement be it is also proposed to cooling fan for cars.
Summary of the invention
In order to solve the large problem of the little noise of above-mentioned flow, the invention provides a kind of high-flow low-noise cooling fan of engine.
In order to achieve the above object, the present invention is achieved by the following technical solutions:
The present invention is a kind of large discharge quiet motor cooling fan, comprise wheel hub, several rotary fan, wheel hub is coordinated with drive motor live axle by inserts, each rotary fan radially arranges and is connected with wheel hub on the outer circumferential face of wheel hub, what be provided with raising rotational stiffness in the outer ring of wheel hub protects solar or lunar halo, be respectively arranged with covering of the fan breach in the junction of each rotary fan and wheel hub, each covering of the fan breach is trapezoidal.
Further improvement of the present invention is: the outer end of each rotary fan all with protect solar or lunar halo and be connected, and the section protecting solar or lunar halo is L-type.
Further improvement of the present invention is: wheel hub is drum and is hollow shell structure.
Further improvement of the present invention is: the side that wheel hub is hollow is provided with radial several floor.
The invention has the beneficial effects as follows: cooling fan of the present invention has the wheel hub of drum, wheel hub is coordinated with drive motor live axle by inserts, several rotary fan radially arranges on the outer circumferential face of wheel hub, a covering of the fan breach is provided with in the outer circumferential face junction of each rotary fan and wheel hub, and breach 3 shape is trapezoidal, for reducing the separation of flow, ensure that no matter at the external lateral portion of rotary fan or the flowing of sufficient air can both be produced at the central part near wheel hub, and have in the outside of wheel hub and protect solar or lunar halo, for improving rotational stiffness, reduce distortion, protect solar or lunar halo for connecting all flabellum outer ends, improve rotational stiffness, reduce distortion, and to protect solar or lunar halo section configuration be L-type, protect solar or lunar halo for raising to bend and torsional stiffness, wheel hub of the present invention or hollow shell structure, reduce fan turns inertia, rotational stiffness is improved by radial rib structure in hollow side.
Because breach is arranged on, each flabellum contacts with hub periphery face cooling fan of the present invention, therefore, it is possible to obtain external lateral portion or the air flow amount of inboard portion effect all fully, in addition, compared with the existing cooling fan flowed with the air producing identical amount, noise is also lower than existing fan.
Structure of the present invention is simple, reasonable in design, novel, reaches the effect of low noise large discharge, and guarantee large discharge basis improves NVH performance.
