Embodiment
In order that those skilled in the art more fully understands technical scheme, below in conjunction with accompanying drawing to this hair
It is bright to be further detailed.
A kind of heavy truck air-conditioning air inlet structure provided as shown in figures 2-6 for the present invention, including radiator grille 1, the radiator grille
It is connected by guide duct 2 with air-conditioning air inlet B；Wherein, radiator grille includes grid 11 and the back shroud matched with the grid 11
13, the bottom of grid 11 is provided with air inlet A1, and the top of back shroud just offers air guide hole to the air inlet, and this programme is led
Air port is located at the underface of the air-conditioning air inlet B, tilts and is enclosed with the grid 11 to remote grid side in back shroud 13
Into the first big cavity of an opening change from the bottom to top；The air-flow of grid is flowed through through air inlet A1, into the first cavity, using inclination
Back shroud purpose one carry out drainage so that air is flowed up along back shroud, further, using the chamber become larger from the bottom to top
Body is easy to air acquisition.
In this programme, guide duct 2 is an acclivitous straight tube structure, bottom and the air guide hole of the guide duct 2
It is connected, the top of the guide duct is to tilt and be connected with the air-conditioning air inlet B at the air-conditioning air inlet B.Using straight
Tubular construction reduces air loss, and the same air-flow for passing through the first cavity using incline structure flows into empty along inclined guide duct
The air inlet of tune.
The present embodiment is by using pair of lamina cavity structure, i.e. guide duct and the first cavity, and guide duct and the first cavity are equal
For incline structure, and it is in smoothing junction so that the air inlet of air-conditioning assembly 4 can be flowed into along inclined plane by flowing into the air-flow of grid, be reduced
The loss of air-flow, improves the operational efficiency of air-conditioning.
As shown in figure 3, in this programme, in guide duct 2 close to the air-conditioning air inlet B locate to be provided with one raise up draw
Plate 5 is flowed, wherein, the bottom of drainage plate 5 is fixed on guide duct bottom surface, and drainage plate is tilted in the same direction with the guide duct 2, flows through wind-guiding
The air-flow of pipe is stopped by wind deflector, so that guide duct exit flow velocity is accelerated, so, in heavy truck Fast marching, not only
Unit interval intake is added, meanwhile, certain induced effect is also acted as, drives the air-flow of bottom to move upwards.
Preferably, in this programme, the gradient of drainage plate is more than the gradient of the guide duct, and purpose flows into wind-guiding
Bottom airflow in pipe effectively can be stopped by drainage plate, and then drainage, increase flow velocity, improve unit interval air inflow.Need
Illustrate, in this programme, drainage plate length is according to air-conditioning air inlet reasonable set, when specifically used, according to air-conditioning air intake
Mouth position carries out reasonable adjusting so that the air for flowing through guide duct flows into air-conditioning air inlet after drainage plate.
As shown in Fig. 3, Fig. 6, in this programme, the guide duct 2 is a rectangular tube, and wherein the top surface of rectangular tube is a middle part
The arc 6 raised up.It is same using the purpose of arc 6, it is more convenient to play drainage effect, coordinate above-mentioned drainage plate real
The stable inflow of existing air.
As shown in figure 3, setting a dedusting plate 12 below wind-guiding tube inlet, dedusting plate is fixed by screws in back shroud
In 13 the first cavitys surrounded with grid 11, the rear and front end of dedusting plate 12 respectively with grid and back shroud against.Operation of air conditioner
When, during vehicle idling, air can suck main frame from grid air inlet, rear postoperculum air vent through double-layer cavity and guide duct；Vapour
When car moves forward, windward, air can pass through bonnet and import cavity in grid air inlet front, suck main frame.Need
Bright, the dedusting version provided in this programme is common mechanism, mainly to entering the larger particles in the air of main frame inlet scoop
There is filtration, and then ensure the air relative clean of suction air-conditioning assembly.
In order to fully ensure that dedusting version can effectively be filtered to flowing into the air in guide duct, in the present embodiment, dedusting
Opening length of the length setting more than air guide hole of plate.
During in view of vehicle idling, the air-flow velocity for flowing into grid is less than normal, in order to increase the air inlet for flowing into air-conditioning air inlet
In effect, this programme, guide duct in the middle part of the air-conditioning air inlet with leaning；The opposed difference in the both sides of first cavity
Provided with an opening, wherein, opening is located on the back shroud and the opening is higher than the air inlet, and the present embodiment opening includes
First opening A2 and the second opening A3, during vehicle idling, air can be passed through from grid air inlet A1, rear postoperculum by A2, A3
Double-layer cavity and guide duct suction air-conditioner host 4, from the both sides of air-conditioning air inlet enter air-conditioning assembly in, using be applied in combination into
One step adds air inlet effect so that again such that air-conditioning air inlet is guaranteed under idling mode.It should be noted that above-mentioned side
Air-conditioning air inlet is divided into three parts by case, i.e., middle part is by guide duct air inlet, and both sides passes through gas inlet hole of divulging information.
As shown in Figure 3, Figure 4, guide duct 2 is connected with the air guide hole by sealing joint strip 3 in this programme.Preferably by
Clamping adhesive tape, can also be realized using common adhesive tape certainly, because generally, guide duct and back shroud use plastics material
Material, therefore connected using adhesive tape, meanwhile, adhesive tape also has good sealing.
In order to further improve sealing when this programme is used, bullet is coated with the junction of back shroud 13 and preceding grid
Property fluid sealant.
In summary, this programme uses pair of lamina cavity structure, i.e. guide duct and the first cavity, guide duct and the first cavity
Incline structure is, and it is in smoothing junction so that the air inlet of air-conditioning assembly, air-conditioning can be flowed into along inclined plane by flowing into the air-flow of grid
Air intake resistance is greatly reduced, and improves the operational efficiency of air-conditioning.Drainage plate and top surface are used for the rectangular tube of arcuate structure simultaneously,
Intake efficiency is improved, the operational efficiency of air-conditioning is effectively increased.
Some one exemplary embodiments of the present invention are only described by way of explanation above, undoubtedly, for ability
The those of ordinary skill in domain, without departing from the spirit and scope of the present invention, can be with a variety of modes to institute
The embodiment of description is modified.Therefore, above-mentioned accompanying drawing and description are inherently illustrative, should not be construed as to the present invention
The limitation of claims.
