Description
Technical field
The invention belongs to a kind of fan vane for car, specially a kind of to have noise-reduction energy-saving radiation fan on vehicle blade.
Background technique
With the development of science and technology, people are also higher and higher to performance requirement and comfort requirement.NVH also becomes each factory
Quotient's focus of attention, to the NVH of each components, more stringent requirements are proposed.Auto NVH refers to noise (Noise), vibration
(Vibration) and sound vibration roughness (Harshness).Noise and vibration usually link together.Sound vibration roughness refers to noise
With the quality of vibration, refer to human body to the subjective feeling of vibration and noise.The main function of air conditioning for automobiles is adjusted in cockpit
The problems such as thermal environment improves occupant's thermal comfort, and the noise of air conditioning for automobiles is too big and air-conditioning work is inefficient greatly drops
The low comfort of occupant.So improving air conditioning for automobiles blade structure for reducing internal car noise and improving the ability to work of air-conditioning
Play the role of very big.Radiator fans are the important components of engine-cooling system, are mounted on motor head,
Basic role is to aid in radiator heat-dissipation, accelerates coolant liquid cooling, its working principle is that by the rotation of motor driven flabellum into
And generating distinguished and admirable, general flabellum is centrosymmetric.Radiator fans bring noise belongs to aerodynamic noise,
It is the Main Noise Sources of automobile.Therefore many automobile vendors and scholar also reduce air conditioning for automobiles and radiator fan noise in research,
Generally have for the noise-reduction method of blade rotational noise: reducing rotation speed of the fan, blade unevenness is homogenized optimizes, adjusts fan
With the spacing of condenser etc..In addition to bringing vibration noise, how further automobile fan also additionally consumes energy in operation,
Reduce the energy loss of fan in the process of running also to have great importance.
Summary of the invention
Aiming at the problem that automobile fan bring vibration noise and energy consumption, the present invention, for bionical object, is mentioned with dragonfly
A kind of fan vane for car design with noise-reduction energy-saving effect out.By improving the structure and shape of flabellum, on this basis
Piezoelectric material is installed and carries out energy regenerating, realizes the effect of energy-saving and noise-reducing.
One kind having noise-reduction energy-saving radiation fan on vehicle blade, including blade body and the balance being arranged in blade body
The section of block, blade body is zigzag, and the upper and lower surface of blade body is covered with the rough pleat of the bionical shape of dragonfly wing
Wrinkle.
Further, the balance weight is fixed on blade body surface by spring；The both ends of spring add pressure
Electric material, piezoelectric material paste the surface in blade body and balance weight respectively.
Further, balance weight is rectangle, is provided with spring on four sides of balance weight.
Further, the vibrational energy that fan rotation process generates is converted electric energy by piezoelectric material, and electric energy is passed through rectification
Circuit is stored in battery.
It is a space multistory three-dimensional structure that dragonfly wing is seen on the whole, to dragonfly wing three-dimensional structure studies have shown that
Random accordion is presented in the cross section of wing, its scrambling is reduced from center back edge.As shown in Figure 1, dragonfly wing
Wing generates good aerodynamic characteristic, is due to its special pleated structure, and fold aerofoil profile upper and lower surface is uneven, and air-flow passes through
This groove surfaces just will appear resident whirlpool, these resident whirlpools can be trapped in inside fold, be filled into the place of recess, from
And fold aerofoil profile is made to be similar to " smooth aerofoil profile ".These aerofoil profiles make dragonfly bear very low air resistance in different state of flights
Power and it is able to maintain body steadiness.The design scheme of flabellum shape of the invention, for bionical object, has references to dragonfly wing with dragonfly
Section fold.Spring had not only played the role of connecting balance weight and flabellum in flabellum but also had had effects that vibration-absorbing denoising, and
The torque that the installation balance blade of balance weight generates under the influence of centrifugal force, enhances the effect of flabellum vibration and noise reducing.With bullet
The vibrational energy that fan rotation process generates is converted electric energy by the piezoelectric material that spring is connected, and what is be connected with piezoelectric patches is one piece
Battery is for storing electric energy produced by piezoelectric material.
The utility model has the advantages that
(1) bionical object of the invention is dragonfly, the fold of the cross section of dragonfly wing is analyzed, by jagged section
Shape applies on air-conditioning flabellum, is conducive to reduce the frictional resistance on flabellum, while installing spring and balance weight on flabellum, benefit
With spring and balance weight come vibration damping and absorbing, to reduce the vibration and noise that flabellum generates in the running, driving is improved
Comfort.
(2) vibration absorber proposed by the present invention can use the vibration during piezoelectric material recycling flabellum rotation
Can, and it is translated into electric energy, it plays the role of energy saving.
Detailed description of the invention
Attached drawing is used to provide further understanding of the present invention, and constitutes part of specification, with reality of the invention
It applies example to be used to explain the present invention together, not be construed as limiting the invention.In the accompanying drawings:
Fig. 1 is the global figure of the motion pattern of dragonfly fold aerofoil profile；
Fig. 2 is side structure schematic view of the invention；
Fig. 3 is isometric side view of the invention；
