Description
Technical field
The utility model belongs to automobile technical field, specifically, and the particularly gas flow guiding structure of manned vehicle headstock.
Background technology
The front bumper of manned vehicle headstock is provided with upper and lower grid, and when manned vehicle travelled, air entered machinery space by upper and lower grid, and condenser and radiator are carried out the air cooling type heat radiation.The deficiency of existing structure is:
1) go up grid horizontal bar because the needs of processing technology, generally be acclivitous, so when manned vehicle travels, the air inlet of last grid is flowed from low to high, has air-flow greatly like this and flows away from the head of condenser and radiator, and this part air-flow does not pass through condenser and radiator, thereby can influence the effect of heat radiation, particularly, position less at last grid leaned on, and when perhaps the speed of a motor vehicle is very fast, shows particularly evident.
2) air-flow that grid enters on directly is flushed on the machinery space plate greatly, the air-flow that Under The Grille enters directly is flushed on the engine lower guard board greatly, can in machinery space, produce eddy current, reduced the air cooling effect to condenser and radiator on the one hand, on the other hand, increase the resistance that manned vehicle travels, reduced the degree of utilization of engine output.
The utility model content
Technical problem to be solved in the utility model is to provide a kind of manned vehicle headstock air intake structure, with the radiating efficiency of effective raising condenser and radiator.
The technical solution of the utility model is as follows: a kind of manned vehicle headstock air intake structure, front bumper (1) is provided with grid (2) and Under The Grille (3), last grid (2) is positioned at the top of Under The Grille (3), in described front bumper (1), also be provided with left deflecting plate (4) and right deflecting plate (5), left side deflecting plate (4) is positioned at, the left end of Under The Grille, right deflecting plate (5) is positioned at, the right-hand member of Under The Grille, the rear of grid (2) is horizontally arranged with baffle upper plate (6) on described, the bottom at Under The Grille (3) rear is along laterally being provided with chin spoiler (7), described baffle upper plate (6), chin spoiler (7), last grid (2) and Under The Grille (3) are encircled into " mouth " font.
The utility model is on the basis of original left deflecting plate and right deflecting plate, baffle upper plate and chin spoiler have been set up, and make four deflecting plates form the distribution of " mouth " font, four deflecting plate combineds action, play water conservancy diversion, air pilot flow direction condenser and radiator that upper and lower grid is entered, to avoid air-flow to flow away from the head of condenser and radiator, guaranteed that basic all air-flows all pass through condenser and radiator so on the one hand, thereby improved the radiating efficiency of condenser and radiator greatly, eliminated the not enough disadvantage of dispelling the heat; On the other hand, can reduce the generation of air whirl, correspondingly reduce the resistance that manned vehicle travels, effectively improve the degree of utilization of engine output.
The bottom of described baffle upper plate (6) is made up of wind-guiding section (6b) on the wind-guiding section (6a) and second on first, on first on the lower end and second of wind-guiding section (6a) upper end of wind-guiding section (6b) be connected as a single entity, and on first the inclination angle (a) of wind-guiding section (6a) and horizontal surface greater than the inclination angle (b) of wind-guiding section (6b) on second with horizontal surface.Moulding is simple on the one hand for above structure, and processing and fabricating is easy, and cost is low; On the other hand, can further reduce the air intake resistance, avoid eddy current to produce, and guaranteed the water conservancy diversion effect.
As preferably, wind-guiding section (6a) be 70-80 ° with the inclination angle (a) of horizontal surface on described first, and the inclination angle (b) of wind-guiding section (6b) and horizontal surface is 50-60 ° on second.
In order to increase structural strength, prevent that baffle upper plate from deforming or damage, at the back side of described baffle upper plate (6) along laterally being formed with first reinforced rib (6c), the preceding high back low dip setting of this first reinforced rib (6c).
The end face of described chin spoiler (7) is following wind-guiding face (7a), the preceding high back low dip setting of this time wind-guiding face (7a).Above structure can be avoided dispersing downwards from the air-flow that Under The Grille enters, and directly rushes at engine lower guard board and produces eddy current, has effectively guaranteed the effect of water conservancy diversion simultaneously.
As preferably, described wind-guiding face (7a) down is 12-20 ° with the angle of horizontal surface.
In order to increase structural strength, prevent that chin spoiler from deforming or damage, along laterally being formed with second reinforced rib (7b), this second reinforced rib (7b) is basically perpendicular to down wind-guiding face (7a) on the bottom surface of described chin spoiler (7).
Beneficial effect: air pilot flow direction condenser and radiator that the utility model can enter upper and lower grid, both guaranteed the radiating efficiency of condenser and radiator, effectively avoided the generation of air whirl again, improve the degree of utilization of engine output greatly, had characteristics such as design is ingenious, simple in structure, transformation is easy, improvement cost is low, applied widely.
