The most corresponding upper and lower two grid opening parts use two pieces of deflectors.Or
Step S13, when grid is with three grids, according to the purpose of design of the 3rd grid, is confirmed whether to arrange water conservancy diversion
Plate.
The function of above-mentioned steps is: owing to the design of grid 4 is generally affected relatively big, outside grid 4 by the outer moulding of vehicle
Shape is not necessarily the structure of rule；Additionally, due to the layout difference of vehicle cabin front anti-collision beam (not shown) is the biggest, if by water conservancy diversion
Plate 1 is designed to complex structure, may result in the problem that arrangement space is inadequate.
In preferred embodiment: step S1 includes:
Step S14, when there is the deviation in direction perpendicular to the ground on forward projection position in refrigerating module 3 and grid 4, water conservancy diversion

Further, step S2 in the present embodiment includes:
Step S21, is located at deflector in cabin and on airflow reflux path intercepts air-flow, makes the air-flow cannot be along former
Flow path is back to refrigerating module or is mounted with the front side of a front-end module of refrigerating module.
During design, owing to idling backflow is one of main design goal of deflector 1, the version of deflector 1 is necessary
Determine according to backflow.And reflux and mainly produce via the gap of front-end module 2 surrounding or front-end module 2 and refrigerating module 3.Lead
Stream plate 1 to play the effect of anti-backflow, it is necessary to realizes intercepting the function in the path of airflow reflux.
When being embodied as, refer to Fig. 2, when vehicle enters idling or speed operation after high load capacity works, now start
In cabin, predominantly fan 5 carries out forced convection, and the direction of its air current flow is T, designs according to the return flow path in flow field, will
Deflector 1 is located in cabin and on airflow reflux path intercepts air-flow, and air-flow can be made cannot to reflux along former flow path
To refrigerating module 3 or the front side of front-end module 2.In preferred embodiment, incorporated by reference to seeing Fig. 3, for the present embodiment deflector

In this step: owing to product manufacturing work should be being met for backflow situation during the structural design optimization of deflector 1
Deflector structure is optimized on the premise of the engineering feasibility such as skill, assembly technology.When being embodied as, owing to front end, cabin exists air-conditioning
The parts such as pipeline, headlight wiring harness and mounting bracket, in order to ensure normal function and the assembly or disassembly space of these parts, must
Deflector 1 is so made to there is design gaps with it.But design gaps will directly affect the effect of deflector 1, it is therefore necessary to it
Effectively control.
Preferably, gap f (deflector 1 and the condenser 30 of refrigerating module 3 front end between deflector 1 and refrigerating module 3
Between gap) less than or equal to 10mm, this is owing to anti-backflow is affected by deflector 1 with the design gaps of refrigerating module 3
Maximum, design load should be the least.
Further, step S3 in the present embodiment includes:
Step S31, is set to the moulding radian of the edge radian dative grid of deflector unanimously, so that deflector and grid
Between gap h uniform.
Step S32, when the opening of grid is bigger, the inclination angle reducing deflector is entered refrigerating module to reduce by grid
Air-flow；Or
Step S33, when grid opening is less or does not mates with refrigerating module, increases the inclination angle of deflector to improve by lattice
Grid enter the air-flow of refrigerating module；Wherein: the inclination angle of deflector is the angle of deflector and refrigerating module windward side.
The effect of above-mentioned steps is: be diversion function for realize deflector 1, needs to control the angle of inclination beta of deflector 1, lead
Stream plate 1 and the matching relationship of grid 4.Owing to considering moulding factor when grid 4 designs, its opening size and position may be with
Refrigerating module 3 can not mate completely.The diversion Design of deflector 1 is just so that and can be imported by grid 4 opening cooling air-flow
Refrigerating module 3.Accordingly, it would be desirable to according to moulding radian, size and the layout of grid 4, adjust deflector angle of inclination beta.Wherein: deflector
The angle of inclination beta deflector 1 and the refrigerating module 3 windward side 3a that refer between angle.
Specifically, deflector 1 edge radian dative grid 4 moulding radian is consistent, to guarantee to mate gap uniformity, can keep
Airflow smooth；When grid 4 opening is bigger, for optimizing car load aerodynamic performance, meeting refrigerating module air quantity requirement
Under premise, the angle of inclination beta that can reduce deflector makes the air-flow being entered refrigerating module 3 by grid 4 reduce；When grid 4 opening relatively
Little or when not mating with refrigerating module 3, then may utilize the guide functions of deflector 1, increase the angle of inclination beta of deflector, improve cold
But air quantity.
In preferred embodiment: step S3 also includes:
Step S34, after the inclination angle of deflector determines, grid, is used with deflector as border until its edge partially enclosed
To reduce air resistance coefficient.
In enforcement, may determine that the cooling air quantity of refrigerating module 3 according to the requirement of cooling system.By adjusting angle of inclination beta
Angle makes cooling air quantity meet requirement.Generally for reduce air resistance coefficient, after angle of inclination beta determines according to cooling air quantity, grid 4 with
Deflector 1 is closed for border to edge part branch, it is illustrated that in 3 the region shown in part A.
Example as shown in table 1 below, that affect cooling flow for certain vehicle change of pitch angle, as shown in Table 1, vehicle is at a high speed
Under operating mode, cooling down the air-flow guide effect through deflector 1 from what grid 4 entered, air-flow velocity improves, and the air quantity of refrigerating module increases
Add；And under high-speed working condition, the air-flow of entrance grid 4, by the guide effect of deflector 1, is forced through refrigerating module 3, it is possible to rise
To the effect reducing air resistance coefficient.
The impact on cooling flow of the table 1-vehicle change of pitch angle
Further, step S4 in the present embodiment includes:
Step S41, on the premise of meeting refrigerating module air quantity requirement, reduce deflector inclination angle, in order to reduce due to
The resistance that vehicle engine room inside causes, wherein: the inclination angle of deflector is the angle of deflector and refrigerating module windward side.This step
In by reducing angle of inclination beta as far as possible, closed lattice, thus reduce the resistance caused due to engine room inside, say, that reduce and lead
Stream plate angle of inclination beta can make the normal pressure acting on deflector 1 reduce, thus reduces aerodynamic drag.
Step S42, reduce deflector and and its there is the gap between the parts of matching relationship.At this moment because between relatively big
There is leakage current in gap, the follow-up as easy as rolling off a log air-flow developing into disorder of leakage current in making cabin, causes aerodynamic drag to increase；Reduce design
Gap is so that high speed downstream is as far as possible by refrigerating module, and does not flow to surrounding and form eddy current so that pneumatic internal resistance subtracts
Few.
Same, as preferred embodiment: step S4 also includes:
Step S43, fits deflector with grid edge, in order to make the air-flow being entered vehicle cabin by grid all flow
Crossing by refrigerating module, in this step, deflector 1 passes through refrigerating module 3 in order to forced draft；Or,
Step S44, deflector matches with the perforate at the beater or beat-up of vehicle cabin, in order to air-flow to be guided out vehicle machine
Cabin.
The function of step S4 is: be optimized the layout of deflector 1 and refrigerating module 3, thus realizes the fall of deflector 1
The effect of low aerodynamic drag, its mainly to deflector 1 and each there is the gap between the parts of matching relationship and deflector
