Abstract
The utility model discloses a kind of novel 11 leaf open type high-efficiency diversion IC. engine cooling fans, include circular open wheel hub and be evenly arranged in 11 blades of hub periphery, 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, be also provided with connecting tendon between the inner side of described guide plate and hub periphery; The axial end of described wheel hub is provided with a circle water conservancy diversion through hole.The utility model has the features such as lightweight, static pressure efficiency is high, balance good, cooling effect is good.
Description
Technical field
The utility model relates to the improvement invention in auto parts and components field, particularly relates to a kind of improvement invention of novel 11 leaf open type high-efficiency diversion IC. engine cooling fans.
Background technique
Traditional IC. engine cooling fan, usual employing 11 leaf open type, it comprises the wheel hub of enclosed construction and is evenly arranged on ten a slice blades of hub periphery, 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, provides a kind of power character and the excellent novel 11 leaf open type high-efficiency diversion IC. engine cooling fans of workability.
In order to solve the problems of the technologies described above, the utility model adopts following technological scheme to realize: this kind of novel 11 leaf open type high-efficiency diversion IC. engine cooling fans, include circular open wheel hub and be evenly arranged in 11 blades of hub periphery, 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, be also provided with connecting tendon between the inner side of described guide plate and hub periphery.
The axial end of described wheel hub is provided with a circle water conservancy diversion through hole.
The beneficial effects of the utility model are the novel 11 leaf open type high-efficiency diversion IC. engine cooling fans after improving, adopt open wheel hub structure, the mobility of air-flow is better, improve ventilation fan amount, ensure the circulation of fan center's cooling blast, cooling effect is better, improves fuel economy; And add guide vane at blade and wheel hub junction, fraction is shunted and enters fan center position, guide vane reduces central gas stream disorder simultaneously, reduce fan noise, internal combustion engine operation is made more steadily to promote the absorption of fan center's heat, promote fan blade intensity simultaneously, make its overall structure better rationally reliable, extend the cooling fan operating life cycle.
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 structure worm's eye view.
Fig. 3 is the utility model structure side view.
Embodiment
Drawings illustrate structure of the present utility model, further illustrate its details by reference to the accompanying drawings more below.Known see accompanying drawing, these novel 11 leaf open type high-efficiency diversion IC. engine cooling fans, include circular open wheel hub 1 and be evenly arranged in 11 blades 2 of wheel hub 1 periphery, the axial end of described wheel hub 1 is provided with a circle water conservancy diversion through hole 6, 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 3 around wheel hub 1 periphery, the stability that reinforced blade 2 is connected with wheel hub 1; The concave surface of described arc surfaced blade 2 is provided with guide plate 4, guide plate 4 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 4 step-down gradually, be also provided with connecting tendon 5 between the inner side of described guide plate 4 and wheel hub 1 periphery.In the utility model, the setting in connection reinforcement portion 3 and add guide vane 2 in blade 2 and wheel hub 1 junction, fraction is shunted and enters fan center position, it is disorderly that guide vane 2 reduces central gas stream simultaneously, reduces fan noise, make internal combustion engine operation more steadily promote the absorption of fan center's heat, promote fan blade 2 intensity simultaneously, make its overall structure better rationally reliable, extend the cooling fan operating life cycle, therefore the utility model has substantive distinguishing features and progress.
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.
