Description
Technical field
The present invention relates to air filter for vehicle, particularly relate to a kind of flow deviding type air filter for vehicle.
Background technique
Air-strainer is one of main parts size in gas handling system, and the effect of air filter for vehicle is for motor provides clean air, sucks at work to produce abrasion with the air of impurity particle and damage with preventing engine.
China Patent No. be 2011201903962, authorized announcement date be February 1 in 2012 day, be called in the patent document of " one takes air filter for vehicle " and disclose a kind of Vehicular cleaner.Existing air filter for vehicle is all the same with the structural type in above-mentioned patent document, be made up of shell and filter core, the inner space of shell is divided into air-inlet cavity and outlet chamber by filter core, in air-inlet cavity, air intlet is set, in outlet chamber, air outlet slit is set, the air entered through air intlet after filter element filtering from air outlet slit supply engine.
Existing air filter for vehicle has the following disadvantages: owing to being subject to the restriction of motor space layout, air outlet and suction port can not be completely just right, therefore the air-flow in air-strainer is not smooth-going rule, air-flow can produce disorderly air-flow through air filtering core device in air-strainer, and disorderly air-flow can cause air column mutually to collide to cause intake resistance to increase; Gas all concentrates on the region process of filtering core device near air outlet slit, and filter core can not be used effectively away from the region of air outlet slit, and the actual effective filtration area of filter core is reduced, and gas circulation narrowed cross section, finally causes intake resistance to increase; The region that after filter core uses one section to wait, inflow-rate of water turbine is large can by dust Severe blockage, the region that inflow-rate of water turbine is little is then as excellent as before, gas handling system intake resistance is caused to worsen upgrading further, and change under the prerequisite that the filter core of having in filter cleaner is not fully utilized, thus shorten the working life of filter core.
Summary of the invention
The invention provides the flow deviding type air filter for vehicle that the little and filter core of a kind of intake resistance can be fully used, solve the problem that the large and filter core of existing air filter for vehicle intake resistance is not fully utilized.
Above technical problem is solved by following technical proposal: a kind of flow deviding type air filter for vehicle, comprise shell and filter core, the inner space of shell is divided into air-inlet cavity and outlet chamber by described filter core, described air-inlet cavity is provided with air intlet, described outlet chamber is provided with air outlet slit, described filter core be positioned at air-inlet cavity side on the surface horizontal have flow distribution plate, described flow distribution plate is provided with grid hole, and described flow distribution plate is positioned at filter core one end near air outlet slit.
The design method of flow distribution plate is, first carries out CFD(Computational Fluid Dynamics to gas handling system when flow distribution plate do not installed by air-strainer) fluid simulation analysis, grasp gas flow characteristic in gas handling system; And then extraction filter core air inlet side, effluent speed of giving vent to anger cloud charts; Finally increase flow distribution plate in filter core air inlet side or side of giving vent to anger, and the percent opening changing flow distribution plate can flow through filter core to air-flow uniform, smooth, the flow distribution plate of this structural type is satisfactory flow distribution plate.
In using process, after engine air throttle is opened, ambient atmos is forced to suck by motor.Air-flow flows through air intlet, air-inlet cavity, filter core, outlet chamber and air outlet slit successively and enters motor.Before air enters filter core, hinder owing to being subject to flow distribution plate, flow direction is changed by flow distribution plate, namely the intensive region of original air-flow becomes near the air-flow in the region of air outlet slit region that loose, original air-flow loosens and becomes intensive away from the air-flow of air outlet slit, thus realize water conservancy diversion, air-flow is uniformly distributed on filter core and smooth-going passing through.
The power equipment that the present invention also comprises filter core frame and drives filter core frame to rotate, described filter core is arranged in described shell by described filter core frame, and described filter core frame is rotatably connected with described body seal, and described flow distribution plate links together with shell.The filter core part stopped because of flow distribution plate entity part is not utilized effectively, and air-flow definitely can not flow through filter core fifty-fifty, also namely the utilization of filter core can be waited to improve part in addition, filter core frame is driven to rotate by power equipment when this design uses, filter core frame drives filter core to rotate, filter core is made also to be change at constantly change, filter core with the relative position of flow distribution plate at the position of air-flow compact district and rarefaction, filter core can be made to be utilized more fully, and filter core utilizes the more abundant time namely meaning that identical filter core can use longer.
