Abstract
The utility model aims at providing an air-inlet grille for an automobile, which can effectively improve the aerodynamics characteristic of the entire automobile. The air-inlet grille for the automobile is in a strip arc shape; the middle of the air-inlet grille for the automobile is an air inlet part at which an air inlet through hole is formed; sealed decorative parts are arranged on two sides of the air inlet part; and the width of the air inlet part is equal to that of an automobile heat dissipater. According to the utility model, the grille is divided into a middle area and two side areas according to positive projections of an automobile condenser and a weather side of the heat dissipater on the air-inlet grille and then the two side areas are set into a sealing state, thus the air-inlet grille is easy for implementation and the cost of the entire automobile is hardly increased. By using the utility model, high-speed air current can be prevented from entering an engine room from two sides of the grille and blowing the areas of wheels, the turbulence intensity of air current of the wheel areas is reduced, the energy loss is reduced, the lifting force of front wheels and the front and rear pressure difference resistance of the entire automobile are reduced, the more excellent automobile aerodynamics performance can be achieved without influencing the heat-dissipating performance and the operation stability of the automobile can be improved.
Description
Technical field
The utility model belongs to the Manufacturing Technology for Automotive Parts field, specially refers to the air-inlet grille of automobile.
Background technology
The main effect of automotive air intake grid has: for radiator provides better air communication channel, make things convenient for radiator heat-dissipation and engine charge; Machinery space inner component such as protection water tank etc. is not flown by foreign matter and beautifies outward appearance etc.Prior art is mainly just considered above Several Factors to the design of automotive air intake grid, considers that seldom the grid air inlet is to the automotive aerodynamics Effect on Performance.
As shown in Figure 1, present automotive air intake grid (3) opening mostly is full open type greatly, and its width is wider than the width of radiator (2) greatly, though satisfied radiating requirements, has ignored the automotive aerodynamics Effect on Performance.Automobile is when running at high speed, too much air enters machinery space by grid (3), can cause two bursts of high speed lateral airflow of grid (3) both sides directly to flow to wheel (1) zone, wheel (1) is in the high speed revolution state, this will make the turbulent flow in wheel (1) zone more random, turbulence intensity increases, and causes the more energy loss; Simultaneously, these two strands of air-flows also can increase the lift of front-wheel, promptly reduce the earth-grasping force of front-wheel (1), make the road-holding property variation of automobile, influence traffic safety; The too much air inlet in grid place also can cause bigger car load pressure drag in addition, influences the car load air resistance coefficient, increases oil consumption.
The utility model content
The purpose of this utility model is to propose a kind of automotive air intake grid that can effectively improve the car load air dynamic behaviour, and this automotive air intake grid is both artistic and practical, implements easily, and is very little to cost impact.
Automotive air intake grid of the present utility model is rectangular arc, and key is automotive air intake grid middle part for being provided with the intake section of air inlet through hole, and the both sides of intake section are the leak free ornamental portion, and the width of described intake section equals the width of automobile radiators.
The intake section of above-mentioned automotive air intake grid has through hole, can allow the air communication mistake, guarantees enough heat dispersions; Ornamental portion is used to beautify outward appearance, and its structure is a leak free, can prevent that air-flow from flowing to wheel from here, influences the aerodynamic performance of automobile.The width that the width of intake section equals automobile radiators can improve heat dispersion to greatest extent.In addition, compare traditional air-inlet grille, the utility model has reduced single-piece air inlet area, therefore can reduce the air resistance coefficient of car load, thereby reduces oil consumption.
Described intake section is the arc of two ends K/UP, height in the middle part of the intake section both sides are compared near the part of wheel like this is higher, therefore the air-flow that enters from the intake section both sides will be littler to the influence of wheel bottom, avoids wheel to produce excessive lift, guarantees traffic safety.
Described ornamental portion is an arc, and its curvature is consistent with the curvature of intake section, to increase aesthetic property.
Described intake section and ornamental portion are structure as a whole, convenient production and installation.
In the middle of the utility model is divided into grid to the orthogonal projection of air-inlet grille according to automobile condenser and radiator windward side and two side areas, then two side areas is made sealing state, implement easily, increase integral vehicle cost hardly.The utility model can avoid high velocity air to be entered machinery space and blowed to the wheel zone by the grid both sides, reduce wheel regional gas stream turbulence intensity, reduce degradation of energy, also reduced simultaneously front-wheel lift and car load front and back pressure drag, do not influence the better automotive aerodynamics performance of realization on the heat dispersion basis, and improving the road-holding property of automobile.
Description of drawings
Fig. 1 is the structural representation of traditional automotive air intake grid;
Fig. 2 is the scheme drawing of automotive air intake cell sructure of the present utility model.
The specific embodiment
Describe the utility model in detail below in conjunction with specific embodiments and the drawings.
Embodiment 1:
As shown in Figure 2, the automotive air intake grid 3 of present embodiment roughly is rectangular arc, utilize of the orthogonal projection of the windward side of radiator 2 to air-inlet grille, grid is divided into A, B, three zones of C, and wherein A, C zone is the leak free ornamental portion, and the B zone is for being provided with the intake section of air inlet through hole, a left side, a-quadrant is risen and is accounted for 7 row openings, right the rising in C zone accounts for 8 row openings, makes A, C zone symmetry substantially, and the width of intake section is the orthogonal projection width of the windward side of radiator 2 to air-inlet grille 3.
Described intake section is the arc of two ends K/UP, height in the middle part of the intake section both sides are compared near the part of wheel 1 like this is higher, therefore the air-flow that enters from the intake section both sides will be littler to the influence of wheel 1 bottom, avoids wheel 1 to produce excessive lift, guarantees traffic safety.Through test, can reduce by 2.33% front-wheel lift.
Described ornamental portion is an arc, and its curvature is consistent with the curvature of intake section, to increase aesthetic property.
Described intake section and ornamental portion are structure as a whole, convenient production and installation.
Present embodiment is made sealing state with the grid integral type with A, C zone, the admission port that keeps the B zone is to provide enough cooling suction quantity, finally guaranteeing that enough cooling air inlets simultaneously, make the car load air resistance coefficient reduce by 5.86%, front-wheel lift also has 2.33% reduction, has realized the obvious lifting of car load aerodynamic performance.
