Abstract
The utility model discloses a device for reducing wind resistance on the surface of a van vehicle body. The device comprises a resistance reducing box and an airflow supplying system, wherein the resistance reducing box is used for being installed on the surface of the van vehicle body, and the airflow supplying system is used for supplying airflow into the resistance reducing box; the resistance reducing box comprises an air cavity and an air film board, the air film board is used for exhausting the airflow in the air cavity, and a plurality of beveled airflow holes which are communicated with the air cavity and used for enabling the surface of the air film board to form an air film layer are distributed in the air film board in an array mode. When a vehicle runs, the surface of the van vehicle body makes indirect contact with external high-speed airflow through the air film layer, and the wind resistance when the vehicle runs is greatly reduced through contact and friction between the air film layer and the external high-speed airflow. Therefore, the device has the advantages of not only saving consumption of fuel oil, but also making the vehicle run more stable and safer.
Description
Technical field
The utility model relates to vehicle energy saving drag reduction technology field, relates in particular to a kind of device that reduces van surface windage.
Background technology
Van transporter is as a kind of important transport facility, has the advantages such as maneuverability, easy to operate, efficient work, load carrying ability be large.Now be widely used in the hauling operation of household electrical appliance, light textile goods, coal, sandstone and other items.Because the car body of van transporter is rectangular structure independently, and car body is long, and in the process of travelling, the comparison of resistance of the wind that the envelope surface is suffered is large, and large windage means that van transporter will consume more energy.
Correlative study shows, in the process of moving, a big chunk consumption of fuel oil is at the friction force on air and envelope surface, compartment, i.e. resistance for vehicle.Rise along with oil equal energy source price, and the minimizing day by day of non-renewable energy resources on the earth, energy-saving and emission-reduction have become the mankind's important mission, and transport facility is the importance that energy consumes, reduce the vehicular transport resistance, particularly the windage tool has very important significance.
Summary of the invention
The utility model provides a kind of device that reduces van surface windage, and purpose is to solve current van transporter in the process of moving by simple and easy to do technological means, because the suffered windage in van surface is large, increases the problem of fuel oil consumption.
For solving the problems of the technologies described above, the utility model is achieved through the following technical solutions:
A kind of device that reduces van surface windage, comprise one for be arranged on the van surface the resistance case falls and for to falling the air-flow feed system of delivery air in the resistance case;
The described resistance case that falls comprises air chamber and for discharging the air film plate of air chamber internal gas flow.
On described air film plate, array distribution has a plurality of that with air chamber, be communicated with and for making air film plate surface form the inclined cutout airflow hole of airflow layer.
The angle of described inclined cutout airflow hole and van surface between 25 °～35 °, preferably 30 °.Described air-flow feed system comprises air pump and connects the pipeline between air chamber and air pump, is provided with flow controller on pipeline.
Compared with prior art, the utility model at least has following advantage and effect:
On the air film plate, array distribution has a plurality of that with air chamber, be communicated with and for making air film plate surface form the inclined cutout airflow hole of air film layer.In Vehicle Driving Cycle, the surface of van-type car body connects with outside high-speed air flow and contacts by the air film interlayer, contact, rub with outside high-speed air flow by this air film layer, greatly reduced the windage of running car, the effect of bringing thus is, not only saved the consumption of fuel oil, and made that running car is more stable, safety.
The utility model is simple and easy to do, cheap, and resistance reducing effect is good, is convenient to promote the wider application.
The accompanying drawing explanation
Fig. 1 is the utility model structural representation.
Fig. 2 is Fig. 1 air film plate structure schematic diagram.
The specific embodiment
Below in conjunction with specific embodiment, the utility model is more specifically described in detail.
Embodiment
As shown in Figure 1 and Figure 2.The utility model reduces the device of van surface windage, comprise one for be arranged on van-type car body 1 surface resistance case 7 falls and for the air-flow feed system to falling resistance case 7 interior delivery airs;
The described resistance case 7 that falls comprises air chamber 7-1 and for discharging the air film plate 5 of air chamber 7-1 internal gas flow.On air film plate 5, array distribution has a plurality of that with air chamber 7-1, be communicated with and for making air film plate 5 surface form the inclined cutout airflow hole 6 of air film layers 8.
The angle on described inclined cutout airflow hole 6 and van-type car body 1 surface, between 25 °～35 °, is preferably 30 °.Inclined cutout airflow hole 6 diameter 2mm, the spacing between each inclined cutout airflow hole 6 and the about 8mm of line-spacing.
Described air-flow feed system comprises air pump 2 and connects the pipeline 4 between air chamber 7-1 and air pump 2, pipeline 4 employing flexible pipes, and air pump 2 adopts common micro air pump.For thering is adjustability, be provided with flow controller 3 on pipeline 4.
Air pump 2 is transported to outside air in air chamber 7-1 by pipeline 4, form in air chamber 7-1 and continue the high-speed pneumatic stream of assembling, high-speed pneumatic stream passes through inclined cutout airflow hole 6, effluent gases lamina membranacea 5 at a high speed, lasting, and at the surperficial air film layer 8 that forms the internal penetration air of air film plate 5.Because constantly producing and consume, air film layer 8 goes out, so this device falls the resistance device also referred to as dynamic penetration air method.The generation of air film layer 8, need to be by means of the energy of air pump 2, and air pump 2 produces air-flows and need to consume certain energy, the energy that only has the energy that consumes when air pump 2 to save much smaller than air film layer 8 drag reduction, and these air film layer 8 drag reductions just have energy-saving effect.
During Vehicle Driving Cycle, (air film layer 8 intersects at two air-flow intersections 10 with outside high-speed air flow 9), the surface of van-type car body 1 by air film layer 8 indirectly with 9 frictions of outside high-speed air flow, the surface that has substituted van-type car body 1 directly with the friction of outside high-speed air flow 9.This means that substitute the surface of van-type car bodies 1 with air film layer 8, not only reduced the windage of Vehicle Driving Cycle, saved the consumption of fuel oil, and make in vehicle traveling process more steadily, safety.
In experimentation, can be by the model experiment means, obtain van-type car body 1 suffered windage size under the condition of the outside high-speed air flow of difference (being wind speed), and record and process measured windage data, draw the best drag reducing efficiency on van-type car body 1 surface.Best drag reducing efficiency is not only relevant with the area of wind speed, van-type car body 1 and the air film plate 5 of van-type car body 1 outside, also relevant with spacing and mis-cut angle between the pore size of inclined cutout airflow hole 6, quantity, Kong Yukong, speed and the pressure of the air pressure stream of also exporting with the air-flow feed system are relevant.On the basis of the above-mentioned technological means that these associations can be put down in writing at this device, through repetition test, can draw.
Embodiment of the present utility model is not restricted to the described embodiments; other are any does not deviate from change, the modification done under Spirit Essence of the present utility model and principle, substitute, combination, simplify; all should be equivalent substitute mode, within being included in protection domain of the present utility model.
