Embodiment
Below in conjunction with accompanying drawing principle of the present utility model and feature are described, institute gives an actual example and only is used for explaining the utility model, is not be used to limiting scope of the present utility model.
In order to solve in the prior art in the vehicle motor intake duct the easily problem of carbon distribution, the utility model provides a kind of vehicle motor intake duct.As shown in Figure 2, vehicle motor intake duct of the present utility model is hollow tubular, what they were different from vehicle transmitter intake duct of the prior art is that the inner wall surface of vehicle motor intake duct 1 of the present utility model is designed to have the hydrophobic surface 1a of self-cleaning function.
The utility model provides a kind of vehicle motor intake duct 1, by its gas-entered passageway inner wall surface is designed to hydrophobic surface 1a, so that the inner wall surface of this intake duct 1 have can self-cleaning function, and can effectively stop microparticle to be adsorbed on the intake duct 1, thereby reducing intake duct 1 carbon distribution phenomenon occurs, reduce the cleaning frequency of intake duct 1 and closure 2, save the cleaning charge of vehicle user and use.
Hydrophobic surface 1a has hydrophoby, can realize the automatically cleaning effect, the many organism surfaces of occurring in nature all have hydrophoby, and for example lotus leaf surface has micro-nano two-dimensional structure, and also have the wax coat of a layered low-surface energy at lotus leaf surface, so that lotus leaf surface has ultra-hydrophobicity, when fluid drips is fallen on the lotus leaf surface, can form a larger wrapping angle, and can roll freely, in addition, the wing of butterfly, the feather of birds also has similar characteristic.Therefore, the surface has hydrophoby need to possess two conditions, and the one, the surface has coarse microscopic appearance, i.e. nano level rough surface, the 2nd, have low-surface-energy.
Therefore, in the present embodiment, preferably, as shown in Figure 3, the inner wall surface that to be processed to form trickle and rough concaveconvex structure 11(on the inner wall surface of vehicle motor intake duct 1 be vehicle motor intake duct 1 is processed to form the micro-rough surface with microscopic appearance), be coated with low surface energy coat 12 outside the concaveconvex structure 11, thereby the surface of low surface energy coat 12 namely forms described hydrophobic surface 1a.In the present embodiment, the micro-rough surface that namely has microscopic appearance by intake duct 1 surface Machining being formed concaveconvex structure 11(), and at these concaveconvex structure 11 outer coating low surface energy coats 12, formation has hydrophobic intake duct 1 inner wall surface, wherein, the micro-rough surface of concaveconvex structure 11(microscopic appearance) can make the gas of flowing through produce little whirlpool near wall, effectively reduce the resistance of gas and wall, and low surface energy coat 12 can reduce the absorption of minitype particle and intake duct 1 inner wall surface.
As shown in Figure 3, common concaveconvex structure 11 can be that the V-type bowl configurations by a plurality of microcosmic with nanometer spacing forms (the waveform micro-rough surface that is namely formed by a plurality of V-type bowl configurations with microcosmic of nanometer spacing), can also be the waveform micro-rough surface that is formed by microcosmic sinusoidal configuration or rectangle square wave structure etc., from actual drag-reduction effect, the concaveconvex structure 11 that the concaveconvex structure 11 that is formed by the V-type bowl configurations of a plurality of microcosmic and microcosmic sinusoidal configuration form is better, and microcosmic rectangle square wave structure is relatively poor, and in some parameter area without drag-reduction effect.From machining angle, the micro-rough surface structure geometric parameter of V-type bowl configurations with microcosmic is simple, the processing preparation is simple, mode with turning processing can process corresponding structure, therefore, in the present embodiment, as shown in Figure 3, preferably, concaveconvex structure 11 adopts the V-type bowl configurations 11a of a plurality of microcosmic to form and (namely processes a plurality of microcosmic V-type bowl configurations 11a with nanometer spacing at the inwall of intake duct 1, the micro-rough surface that has microscopic appearance with formation), can change the air flow field on 1 surface, throttle inflow road, reduce the resistance of air and microparticle and wall.
As shown in Figure 4, it is that intake duct 1 inner wall surface forms the micro-rough surface with microscopic appearance that intake duct 1 inner wall surface forms concaveconvex structure 11(), when air stream during through intake duct 1 inner wall surface, to in the V-type bowl configurations 11a of microcosmic, produce little whirlpool, thereby so that free incoming flow flows at parallel artificial little whirlpool, and only contact with little whirlpool, do not contact with intake duct 1 inner wall surface, as shape roller in a row between intake duct 1 inner wall surface and incoming flow, and played similar " roller bearing " the same effect, so that the sliding friction of top tank air and intake duct 1 inner wall surface is converted to rolling friction, thereby reach the purpose of reducing noise and drag.
In addition, in the present embodiment, as shown in Figure 3, preferred, the width a of the V-type bowl configurations 11a of microcosmic is 5 ~ 20 microns, and degree of depth b is 10 ~ 20 microns.When the width a of the V-type bowl configurations 11a of microcosmic is 5 ~ 20 microns, when degree of depth b was 10 ~ 20 microns, it was best to reduce the resistance of air effect.
In addition, in the present embodiment, preferred, the thickness of low surface energy coat 12 is 1 ~ 2 micron.The material of low surface energy coat 12 is teflon, can also adopt fluoroacrylic resin or multiple fluorocarbon coating, and similar character is also arranged.
Second purpose of the present utility model is to provide a kind of vehicle motor that vehicle motor intake duct 1 of the present utility model is installed.
The 3rd purpose of the present utility model is to improve a kind of vehicle that vehicle motor intake duct 1 of the present utility model is installed, especially a kind of automobile.
The above is preferred implementation of the present utility model; should be understood that; for those skilled in the art; under the prerequisite that does not break away from principle described in the utility model; can also make some improvements and modifications, these improvements and modifications also should be considered as protection domain of the present utility model.
