Cooling, the radiator by air-conditioning system is that driver's cabin carries out cooling heat transferring.In order to guarantee the performance of heat exchanger, need in vehicle
There are enough air quantity by radiator and radiator under driving cycle, and requires the heat of fan discharge under idling operation
Before wind cannot be back to radiator, avoid hot wind by lasting heating, final heat conduction radiator can not radiate, and influence air-conditioning just
Often work.It is detected by experiment: being directed to traditional technology, there are before hot air reflow to radiator under idling operation, cause
Radiator maximum temperature can reach 102 DEG C, seriously affect the normal work of air-conditioning system.Under the operating condition of 80kph speed, grid
Air inlet not well by radiating module, reduce heat dissipation performance；For this purpose, design and develop it is a kind of improve heat dissipation effect it is pure
It is particularly important that electric car air guide structure, which seems,.
Utility model content
The utility model is to solve technical problem present in well-known technique, provides a kind of pure electric automobile air conducting knot
Structure, which increases air guide structure on radiator periphery, and then improves the heat dissipation of pure electric automobile
Effect.
The purpose of the utility model is to provide a kind of pure electric automobile air guide structures, in air inlet grid (1) and radiate
Wind deflector (3) are set between device (2)；The front end of above-mentioned wind deflector (3) is connect with the lower end of air inlet grid (1)；Above-mentioned wind deflector
(3) rear end is connect with the upper end of radiator (2)；The two sides of above-mentioned wind deflector (3) are connect with radiator installation point respectively；It is above-mentioned
It is air duct between wind deflector (3) and car bonnet (4).
Further, above-mentioned wind deflector (3) is made of plastics.
The utility model has the advantages and positive effects of:
The utility model can be effectively reduced the heat before radiator by installing air guide structure before radiator and flow back
Temperature, while can be promoted when vehicle driving through the air inlet air quantity of Heat Sink A heat sink.It can be with from analysis result
Significantly find out, after increasing refluence attachment, hot reflux problem is improved before radiator.It is detected by experiment: with biography
System technology compares, and above-mentioned pure electric automobile air guide structure can reduce the temperature of heat reflux when parking is turned on the aircondition
80 DEG C are reduced to from 90 DEG C；80km/h speed when driving, can will be mentioned by the air inlet air quantity of radiator from 0.815kg/s
0.889kg/s is risen to, about 9% performance is improved.
Detailed description of the invention

Fig. 2 is the structure chart of the preferred embodiment in the utility model；
Fig. 3 is the temperature cloud picture of traditional pure electric automobile；
Fig. 4 is the temperature cloud picture using pure electric automobile after technical solutions of the utility model.
Wherein: 1, entering the wind grid；2, radiator；3, wind deflector；4, car bonnet.
Specific embodiment
For the utility model content, feature and effect that can further appreciate that the utility model, the following examples are hereby given, and
It is described in detail with the accompanying drawings as follows:
Referring to Fig. 1, being directed to traditional electric car, air-flow is directly opposite with radiator 2 after the air inlet entrance of grid 1,
In running at high speed, air-flow takes away the thermal energy on radiator 2, but under idling operation, the high temperature quilt that radiator 2 comes out
The air-flow blowback entered from air inlet grid is returned on radiator；The temperature of radiator is caused constantly to increase at this time；It is red by experiment hot
Outer detection, Fig. 3 are the temperature cloud picture of traditional pure electric automobile；The subregional temperature of radiator top is high as can be seen from Figure 3
In 90 DEG C, this can reduce the radiating efficiency of radiator, even result in radiator failure:
For this purpose, referring to Fig. 2, this preferred embodiment increases wind deflector 3 on the basis of traditional technology, specifically: into
Wind deflector 3 is set between air grid lattice 1 and radiator 2；The front end of above-mentioned wind deflector 3 is connect with the lower end of air inlet grid 1；It is above-mentioned to lead
