Abstract
The invention aims at providing a guide edge concave-convex fan, comprising a wheel hub and blades, wherein the blades are arranged on the wheel hub, each blade comprises a blade following edge and a blade guide edge, each blade following edge is in a line shape, each blade guide edge is in a sine curve shape, and each blade guide edge produces a counter-rotating vortex when the blades rotate. According to the invention, appearance structure of each blade is changed while no additional device is added. More electrical energy can be converted during wind power generation.
Description
Technical field
What the present invention relates to is a kind of wind energy field, specifically blower fan.
Background technique
Wind energy advantage huge with its amount of accumulateing as green energy resource, that can regenerate, distribute extensively, not have to pollute is favored by various countries.Converting wind energy to electric energy has had than mature technique, and development potentiality and application prospect are arranged very much.The quality and the fan efficiency of fan blade performance are closely related.Therefore, exploitation is a kind of efficient and blower fan function admirable is very meaningful.
Summary of the invention
The object of the present invention is to provide the concavo-convex blower fan of the guide lug that when wind-power electricity generation, can change more electric energy.
The objective of the invention is to realize like this:
The concavo-convex blower fan of guide lug of the present invention comprises wheel hub, blade, and blade installation is on wheel hub; It is characterized in that: described blade comprises blade lagging edge and blade guide lug; The blade lagging edge is shaped as straight line, and the blade guide lug is shaped as sinusoidal curve, and the blade guide lug produces the whirlpool of counterrotating during the blade rotation.
The present invention can also comprise:
1, R is for being the radius that blade edge is arrived in the center of circle with the wheel hub center, and r is the minimum range of sinusoidal curve initial position and root of blade on the blade, and h is the sinusoidal curve wave height, R: r: h=110: 7: 30.
2, the number of described blade is 3, be the center of circle to the radius of blade edge with the wheel hub center is 0.55m, and the minimum range of sinusoidal curve initial position and root of blade is 0.15m on the blade, and the sinusoidal curve wave height is 0.035m.
Advantage of the present invention is: the present invention only changes the form structure of blade, and does not increase additional device.When wind-power electricity generation, can change more electric energy.
Description of drawings
Fig. 1 is concavo-convex fan blade schematic representation;
Fig. 2 is blade profile contrast schematic representation.
Embodiment
For example the present invention is done description in more detail below in conjunction with accompanying drawing:
In conjunction with Fig. 1～2, the concavo-convex blower fan of guide lug of the present invention comprises wheel hub 1, blade 2; Blade 2 is installed on the wheel hub 1, and blade 2 comprises blade lagging edge 4 and blade guide lug 3, and blade lagging edge 4 is shaped as straight line; Blade guide lug 3 is shaped as sinusoidal curve; Blade guide lug 3 produces the whirlpool of counterrotatings during blade 2 rotation, and R is for being the radius that blade 2 edges are arrived in the center of circle with wheel hub 1 center, and r is the minimum range of sinusoidal curve initial position and blade 2 roots on the blade 2; H is the sinusoidal curve wave height, R: r: h=110: 7: 30.
The number of blade 2 is 3, provides one group of concrete parameter of blower fan below:
Be the center of circle to the radius at blade 2 edges with wheel hub 1 center be 0.55m, the minimum range of sinusoidal curve initial position and blade 2 roots is 0.15m on the blade 2, and the sinusoidal curve wave height is 0.035m.
Concavo-convex fan blade 2 is when work, and concavo-convex guide margin 3 places of blade 2 can produce the whirlpool of counterrotating, and concavo-convex guide margin 3 can absorb the whirlpool that produces, and this part energy is re-injected in the fluid, improves the aeroperformance of blade.Owing to be that sinusoidal curve and blade 2 root places do not add concavo-convex tubercle, so the aspect ratio of concavo-convex fan blade 2 is identical with the aspect ratio of parent form fan blade.The aerofoil profile of blade is NACA4412, and guarantees that disk ratio is identical with the parent form fan blade.
