Abstract
The utility model discloses the bionical sawtooth blade structure of a kind of multilayer, wheel hub is placed with multiple blade unit in the form of a ring, the fan leaf composition that each blade unit increases progressively successively by multiple mutually stacked and length, leaves gap between two fan leafs adjacent in blade unit; Fan leaf is provided with bionical saw tooth structure away from the end face of wheel hub.Blade unit adopts this multilayer steps formula structure, effectively reduce the eddy current loss that the outer peripheral wind speed difference of fan leaf produces, wind speed difference is produced uniformly at the edge of each fan leaf, rationally avoid ship earthquake region, improve fan leaf aerodynamic quality, fan leaf is made to have lower noise when same rotational speed, larger flow and the static pressure of Geng Gao; Fan leaf edge is provided with bionical saw tooth structure, and its design concept derives from the analysis to pinion edge, and the class saw tooth structure of pinion edge is conducive to improving fan leaf aerodynamic performance, also can reduce wind speed difference, thus reduces eddy current loss, reaches energy-conservation effect.
Description
Technical field
The utility model relates to the bionical sawtooth blade structure of a kind of multilayer.
Background technique
Existing blade structure, the most blades mainly comprising a central part and extend from this central part periphery, this blade structure is combined with fan board and forms fan, to dry heat radiation to user.
But existing blade structure aerodynamic quality is poor, noise is large, can not meet the demand of user.
Model utility content
Problem to be solved in the utility model is to provide a kind of good aerodynamic quality, the bionical sawtooth blade structure of noise multilayer that is little, good energy-conserving effect.
In order to solve the problems of the technologies described above, the technical solution adopted in the utility model is: the bionical sawtooth blade structure of a kind of multilayer, comprise wheel hub, it is characterized in that, described wheel hub is placed with multiple blade unit in the form of a ring, the fan leaf composition that each described blade unit increases progressively successively by multiple mutually stacked and length, leaves gap between two fan leafs adjacent in described blade unit; Described fan leaf is provided with bionical saw tooth structure away from the end face of described wheel hub.
Preferably, the bionical sawtooth blade structure of above-mentioned multilayer, the quantity of wherein said blade unit is four.
Preferably, the bionical sawtooth blade structure of above-mentioned multilayer, wherein each described blade unit includes three fan leafs.
Preferably, the bionical sawtooth blade structure of above-mentioned multilayer, the distance in same described blade unit between every two adjacent fan leafs is all identical.
Preferably, the bionical sawtooth blade structure of above-mentioned multilayer, in same described blade unit, the indent of every two adjacent fan leafs is all identical.
As long as technique effect of the present utility model is embodied in: the fan leaf composition that blade unit increases progressively successively by multiple mutually stacked and length, adopt this multilayer steps formula structure, effectively reduce the eddy current loss that the outer peripheral wind speed difference of flabellum produces, wind speed difference is produced uniformly at the edge of each flabellum, rationally avoid ship earthquake region, improve fan-blade air power performance, make flabellum have lower noise when same rotational speed, larger flow and the static pressure of Geng Gao; Fan leaf edge is provided with bionical saw tooth structure, also can reduce wind speed difference, thus reduces eddy current loss, reaches energy-conservation effect.
Accompanying drawing explanation

Embodiment
Below in conjunction with accompanying drawing, embodiment of the present utility model is told about further, be easier to make the technical solution of the utility model understand and grasp.
As shown in Figure 1, 2, the bionical sawtooth blade structure of a kind of multilayer, comprise wheel hub 1, centered by wheel hub 1, position is provided with the cylindrical body of through hole 11.Wheel hub 1 is placed with in the form of a ring four blade units 2, each blade unit 2 forms by three mutual stacked and length increases progressively successively fan leafs 21, leaves gap between two fan leafs 21 adjacent in blade unit 2; Fan leaf 21 is provided with bionical saw tooth structure 22 away from the end face of wheel hub 1.
Preferably, the distance in same blade unit 2 between every two adjacent fan leafs 21 is all identical, and in same blade unit 2, the indent of every two adjacent fan leafs 21 is all identical.
Blade unit 2 in the utility model forms by multiple mutually stacked and length increases progressively successively fan leaf 21, adopt this multilayer steps formula structure, effectively reduce the eddy current loss that the outer peripheral wind speed difference of fan leaf 21 produces, wind speed difference is produced uniformly at the edge of each fan leaf 21, rationally avoid ship earthquake region, improve fan leaf 21 aerodynamic quality, make fan leaf 21 have lower noise when same rotational speed, larger flow and the static pressure of Geng Gao; Fan leaf 21 edge is provided with bionical saw tooth structure 22, also can reduce wind speed difference, thus reduces eddy current loss, reaches energy-conservation effect.
Above an embodiment of the present utility model has been described in detail, but described content being only preferred embodiment of the present utility model, can not being considered to for limiting practical range of the present utility model.All equalizations done according to the utility model application range change and improve, and all should still belong within patent covering scope of the present utility model.
