Abstract
The utility model discloses a 11 bucket rings shape cooling fan, describe open hub and arrange evenly that this blade outer end cladding has outer ring body, its characterized in that at 11 blades of hub periphery including the ring: the blade is the crooked cambered surface form that forms outside width direction goes to court, root department one end height, the low slope of the other end that blade and hub are connected set up, and the high -end department of root forms connection strengthened portion around the extension of hub periphery, be equipped with the water conservancy diversion piece on the concave surface of cambered surface form blade, the water conservancy diversion piece is by crooked extension the in the outside of the high -end root low side to the blade of the root of blade, and the highly step -down gradually of water conservancy diversion piece. The utility model relates to a rationally, compare with traditional internal -combustion engine fan, have characteristics such as light in weight, the static pressure is efficient, the equilibrium good, the cooling effect is good.
Description
Technical field
The utility model relates to the improvement invention in automobile component field, particularly relates to a kind of improvement invention of 11 leaf joint shape cooling fans.
Background technique
Traditional internal-combustion engine annular cooling fan, usual employing 11 blade shape, it comprises the wheel hub of enclosed construction and is evenly arranged on ten a slice blades of hub periphery, blade outer end is coated with outer ring body, without strengthening structure on usual blade, cause blade strength low, and it is comparatively simple with the connection of hub periphery, yielding and unstable, and without flow guide structure on blade, when IC. engine cooling fan works, its central gas stream there will be disorder and produces noise, cause internal combustion engine operation not steady, make mobility and the poor radiation of air, thus reduce the radiating efficiency of internal-combustion engine, the consumed power of motor is increased, so that reduce the working life of motor, enclosed wheel hub structure simultaneously, its fan center's part radiating effect is not good, and raw materials consumption is large.
Model utility content
Technical problem to be solved in the utility model overcomes the deficiencies in the prior art, the 11 leaf joint shape cooling fans providing a kind of good balance effect, cooling effect good.
In order to solve the problems of the technologies described above, the utility model adopts following technological scheme to realize: this kind 11 leaf joint shape cooling fan, include circular open wheel hub and be evenly arranged in 11 blades of hub periphery, this blade outer end is coated with outer ring body, it is characterized in that: described blade bends outwards formation arc surfaced in the direction of the width, one end, root place that described blade is connected with wheel hub is high, the other end low dip is arranged, and the high-end place of root extends to form connection reinforcement portion around hub periphery; The concave surface of described arc surfaced blade is provided with guide plate, and guide plate is extended by the outer lateral bend of the high-end root low side to blade of the root of blade, and the height of guide plate step-down gradually.
The axial end of described wheel hub is provided with a circle water conservancy diversion through hole.
Some wheel hub stiffening ribs are provided with between the water conservancy diversion through hole of described wheel hub and blade.
The beneficial effects of the utility model are 11 leaf joint shape cooling fans after improving, by arranging the ring-type outer ring body of coated blade at the outer end place of blade, make blade can reduce air turbulence at rotary course, reduce the noise that blade tip produces, reach more quiet effect, and the setting of outer ring body makes blade better be ensured in the degree of balance of rotary course, it is more steadily quiet that global design makes motor run; The setting of guide plate makes fraction shunt and enters fan center position, and minimizing central gas stream is disorderly simultaneously, makes internal combustion engine operation more steady, promotes the absorption of fan center's heat.
Accompanying drawing explanation
Below in conjunction with accompanying drawing, embodiment of the present utility model is described in further detail.
Fig. 1 is structural representation of the present utility model.
Fig. 2 is the utility model inverse layer structure schematic diagram.
Embodiment
Drawings illustrate structure of the present utility model, further illustrate its details by reference to the accompanying drawings more below.This 11 leaf joint shape cooling fan, include circular open wheel hub 1 and be evenly arranged in 11 blades 2 of wheel hub 1 periphery, this blade 2 outer end is coated with outer ring body 3, described blade 2 bends outwards formation arc surfaced in the direction of the width, one end, root place that described blade 2 is connected with wheel hub 1 is high, the other end low dip is arranged, and the high-end place of root extends to form connection reinforcement portion 4 around wheel hub 1 periphery; The concave surface of described arc surfaced blade 2 is provided with guide plate 5, guide plate 5 is extended by the outer lateral bend of the high-end root low side to blade 2 of the root of blade 2, and the height of guide plate 5 step-down gradually, guide vane 2 makes fraction shunt and enters fan center position, reduce central gas stream disorderly simultaneously, make internal combustion engine operation more steadily promote the absorption of fan center's heat.The axial end of described wheel hub 1 is provided with a circle water conservancy diversion through hole 6, is provided with some wheel hub 1 stiffening ribs 7 between water conservancy diversion through hole 6 and blade 2, and that improves wheel hub 1 is subject to force intensity.In the utility model, root guide plate 5 being arranged blade 2 makes guide plate 5 have better water conservancy diversion effect on the one hand, makes being strengthened by force intensity of blade 2 root, so guide plate 5 also has the effect be equal to stiffening rib 7 while water conservancy diversion on the other hand; Open wheel hub 1 structure makes the mobility of air-flow better, improves ventilation fan amount, reduces the consumption of raw material, and contribute to the circulation and the reduction noise that ensure fan center's cooling blast, cooling effect is better, improves fuel economy simultaneously.
In sum, these are only preferred embodiment of the present utility model, be not intended to limit protection domain of the present utility model.All within spirit of the present utility model and principle, any amendment done, equivalent replacement, improvement etc., all should be included within protection domain of the present utility model.
