Description
Technical field
The invention belongs to automotive front end cooling systems, and in particular to a kind of intercooler flow-guiding structure.
Background technique
With rising year by year year by year plus sternly with requirement of the user to vehicle dynamic quality for national emission standard, turbocharging vehicle
Type has been increasingly becoming the first choice of major automobile industry, and intercooler is the important component of pressure charging system, and effect is to reduce to increase
High temperature air temperature after pressure to reduce engine heat load, improve air inflow, and then improves the power of engine.
It is protected behind grid before passenger car intercooler is placed on more currently on the market, the cooling systems front end such as radiator, without special
Intercooler inlet channel, intercooler air inflow is less, leads to intercooler to turbocharging high temperature air cooling effect and pays no attention to
Think, so that the effective volumetric efficiency of engine is low, and then reduces engine power, intake air temperature is excessively high, also engine can be caused quick-fried
The failures such as shake；Meanwhile being protected after car crass in order to be formed to pedestrian lower leg, need front bumper to have certain support stiffness,
To prevent pedestrian's knee angle of bend excessive, after being arranged in front bumper grid due to intercooler, flow-guiding structure needs to consider
Have to the promotion of bumper rigidity and centainly takes into account.
Summary of the invention
The invention discloses a kind of intercooler flow-guiding structures, promote intercooler chip body cooling efficiency simultaneously, take into account preceding insurance
Rigidity is promoted.
A kind of intercooler flow-guiding structure, including：Intercooler chip body, wind deflector and front bumper；
After the intercooler chip body is arranged in front bumper, direction is entered the wind in face of front bumper grid mouth；
The wind deflector is arranged in intercooler chip body circumferential direction, extends along air inlet direction front-bumper；
The wind deflector extends in front bumper crumple deformation range, is used to support and the portions crush of front bumper is stopped to become
Shape.
Further, wind deflector includes upper guard board and lower backplate, and lower backplate extends in front bumper crumple deformation range,
It is used to support the portions crush deformation for stopping front bumper.
Further, the lower backplate and front bumper are kept at a distance within the scope of 5mm to 15mm.
Further, the hardened structure of outer bell mouth expanding is extended in wind deflector upper guard board and lower backplate edge air inlet direction；Lower backplate
Continue to setting the crumple support plate extended in front bumper crumple deformation range before outer bell mouth expanding plate.
It further, further include intercooler frame, the intercooler chip body is mounted in intercooler frame, the intercooler
Frame be used to be mounted on vehicle body；Mounting bracket is respectively set in the upper guard board and lower backplate, and is installed by mounting bracket
On affiliated intercooler frame.
Further, the lower backplate length is greater than upper guard board length, and length both ends setting mounting hole by under for protecting
Plate is fixed on vehicle body；Along vehicle body front-rear direction, reinforcing rib is arranged in lower backplate plate body.
Further, wind deflector further includes left backplate and right backplate, and left backplate and right backplate are extended outer along air inlet direction
The hardened structure of bell mouth expanding.
Advantageous effects of the present invention are：Extend wind deflector in the circumferential edge air inlet direction front-bumper of intercooler chip body,
Wind deflector extends in front bumper crumple deformation range, is used to support the portions crush deformation for stopping front bumper.Wind deflector
It is trapped among the extension of intercooler chip body circumferential direction front-bumper, forms air-flow guide channel between bumper and intercooler chip body, it will
Air-flow is effectively guided to intercooler chip body and is cooled down to it, can increase intercooler intake, be effectively reduced engine into
Temperature degree promotes engine charging efficiency.Meanwhile the range stretched of wind deflector has reached and extends to front bumper crumple deformation range
It is interior, it is used to support the portions crush deformation for stopping front bumper, and meet and improve front bumper rigidity, is effectively reduced and collided
In journey the problem of pedestrian lower leg bending injury.Structure of the invention is compact, simple, realizes intercooler cooling efficiency and front bumper
Collision safety coefficient is double to be promoted, and not additional increase labyrinth, at low cost.

Specific embodiment
It elaborates with reference to the accompanying drawing to the present invention.
As shown in Figures 1 to 5, a kind of intercooler flow-guiding structure disclosed by the invention, including：Intercooler chip body 4, intercooler
Frame 2, wind deflector 1 and front bumper 3.Intercooler chip body 4 is arranged in after front bumper 3 and is mounted in intercooler frame 2, face
Direction is entered the wind to 3 grid mouth of front bumper, intercooler frame 2 be used to be mounted on vehicle body.
Wind deflector 1 is arranged in intercooler chip body 4 circumferentially, extends along air inlet direction front-bumper, wind deflector includes upper shield
Plate 11, lower backplate 12, left backplate 16 and right backplate 14.
Mounting bracket 13 is respectively set in upper guard board 11 and lower backplate 12, and is mounted on intercooler frame by mounting bracket 13
On 2.Upper guard board 11, lower backplate 12, left backplate 16 and right backplate 14 and the installation fit clearance of intercooler frame 2 pass through cavernous body
5 are sealed.Cavernous body 5 is fixed in upper guard board 11, lower backplate 12, left backplate 16 and right backplate 14 by adhesive tape, to ensure
Cold air into channel all flows through intercooler chip body 4.
Lower 12 length of backplate is greater than 11 length of upper guard board, and length both ends setting mounting hole 15 is for lower backplate to be fixed on
On vehicle body, along vehicle body front-rear direction, reinforcing rib, wind deflector upper guard board 11 and lower backplate 12 is arranged along air inlet direction in lower backplate plate body
Extend the hardened structure of outer bell mouth expanding, with 4 vertical direction angle of intercooler chip body between 0 ~ 30 °；Lower backplate 12 is extending out loudspeaker
Continue the crumple support plate 121 extended in front bumper crumple deformation range to setting before oralia, crumple support plate 121 with
Front bumper is kept at a distance within the scope of 5mm to 15mm.
Referring to fig. 4, the left backplate 16 and right backplate 14 of wind deflector extend the hardened structure of outer bell mouth expanding along air inlet direction, with
4 vertical direction angle of intercooler chip body is between 0 ~ 30 °.
As shown in fig. 7,1 air intake structure of wind deflector constructs cold in one jointly with front bumper 3 under running conditions of vehicle
It is cooling to intercooler chip body 4 to be introduced directly into a large amount of front end Cryogenic air incoming flows for device cooling wind inlet channel.
As shown in fig. 6, front end Cryogenic air incoming flow does not enter intercooler chip body 4 largely in no wind deflector 1, cause
The decline of 4 heat dissipation effect of intercooler chip body.
Structure disclosed by the invention can promote 30% or more intercooler cooling intake, the decline of intercooler air outlet temperature
7 DEG C ~ 10 DEG C, promote 3% or more engine power performance.And when vehicle and pedestrian occur to collide in the front-back direction, due to lower shield
Plate 12 is in 3 crumple deformed area of front bumper, and has supporting role to it, the preceding portion of guaranteeing the minimum will not occur it is severely deformed, can be right
Pedestrian shank is preferably supported, and can be effectively reduced pedestrian shank because of injury caused by knee severe bends.
