Detailed description of the invention
In order to make those skilled in the art understand technical scheme of the present invention better, below in conjunction with accompanying drawing, the present invention is further detailed.
Be one provided by the invention heavily card air-conditioning air inlet structure as shown in figures 2-6, comprise radiator grille 1, described radiator grille is connected with air-conditioning admission port B by guide duct 2; Wherein, the back shroud 13 that radiator grille comprises grid 11 and matches with described grid 11, admission port A1 is provided with bottom described grid 11, the top of back shroud just offers air guide hole to described admission port, this programme air guide hole is positioned at immediately below described air-conditioning admission port B, back shroud 13 to away from grid lopsidedness and with described grid 11 surround one from the bottom to top opening become the first large cavity; Flow through the air-flow of grid through admission port A1, enter the first cavity, adopt the back shroud object one tilted to carry out drainage, air upwards flowed along back shroud, become large cavity be from the bottom to top gradually convenient to air acquisition further, adopt.
In this programme, guide duct 2 is an acclivitous straight tube structure, and the bottom of described guide duct 2 is connected with described air guide hole, and the top of described guide duct is tilt to described air-conditioning admission port B place and be connected with described air-conditioning admission port B.Adopt straight tube structure to reduce air loss, the same air-flow adopting incline structure to make to flow through the first cavity flows into the admission port of air-conditioning along the guide duct tilted.
The present embodiment is by adopting pair of lamina cavity structure, i.e. guide duct and the first cavity, and guide duct and the first cavity are incline structure, and smooth connection, make the air flow energy flowing into grid flow into the admission port of air-conditioning assembly 4 along dip plane, decrease the loss of air-flow, improve the operating efficiency of air-conditioning.
As shown in Figure 3, in this programme, in guide duct 2, be provided with a drainage plate raised up 5 near described air-conditioning admission port B place, wherein, the bottom of drainage plate 5 is fixed on guide duct bottom surface, and drainage plate and described guide duct 2 tilt in the same way, the air-flow flowing through guide duct is stopped by deflector shield, thus guide duct exit flow velocity is accelerated, like this, when heavy card Fast marching, not only add unit time intake, meanwhile, also play certain induced effect, drive the air-flow upward movement of bottom.
Preferably, in this programme, the degree of dip of drainage plate is greater than the degree of dip of described guide duct, and object makes the bottom airflow energy actv. flowed in guide duct be stopped by drainage plate, and then drainage, increases flow velocity, improves unit time suction quantity.It should be noted that, in this programme, drainage plate length, according to air-conditioning ventilation inlet reasonable set, when specifically using, being carried out reasonable adjusting according to air-conditioning ventilation inlet position, being made the air flowing through guide duct after drainage plate, flow into air-conditioning admission port.
As shown in Fig. 3, Fig. 6, in this programme, described guide duct 2 is a rectangular tube, and wherein the end face of rectangular tube is the arc 6 raised up in the middle part of in the of.Adopt the object of arc 6 same, more conveniently play drainage effect, coordinate above-mentioned drainage plate to realize the stable inflow of air.
As shown in Figure 3, arrange a dedusting plate 12 below guide duct entrance, dedusting plate is fixed by screws in the first cavity that back shroud 13 and grid 11 surround, the rear and front end of dedusting plate 12 respectively with grid and back shroud against.During operation of air conditioner, during vehicle idling, air can suck main frame from grid ventilation inlet, bonnet after ventilation aperture double-layer cavity and guide duct; When automobile moves forward, windward, air can import cavity by bonnet smoothly in grid air inlet front, sucks main frame.It should be noted that, the dedusting version provided in this programme is common mechanism, mainly has filtration to the larger particles entered in the air of main frame inlet scoop, and then ensures the air relative clean sucking air-conditioning assembly.
In order to fully ensure that dedusting version effectively can be filtered the air flowed in guide duct, in the present embodiment, the length setting of dedusting plate is greater than the Opening length of air guide hole.
When considering vehicle idling, the air-flow velocity flowing into grid is less than normal, and in order to increase the air inlet effect flowing into air-conditioning admission port, in this programme, the middle part of guide duct and described air-conditioning admission port leans; What the both sides of described first cavity were opposed is respectively equipped with an opening, wherein, opening to be located on described back shroud and described opening higher than described admission port, the present embodiment opening comprises the first opening A2 and the second opening A3, during vehicle idling, air can suck air-conditioner host 4 by A2, A3 through double-layer cavity and guide duct from grid ventilation inlet A1, rear postoperculum, enter from the both sides of air-conditioning admission port in air-conditioning assembly, employing combinationally uses and further increases air inlet effect, makes air-conditioning air inlet be guaranteed equally under making idling mode.It should be noted that, air-conditioning admission port is divided into three parts by such scheme, and namely middle part is by guide duct air inlet, and both sides is by breather port air inlet.
As shown in Figure 3, Figure 4, in this programme, guide duct 2 is connected by sealing joint strip 3 with described air guide hole.Preferably adopt clamping adhesive tape, common adhesive tape certainly also can be adopted to realize, due to generally, guide duct and back shroud all adopt plastic material, and therefore employing adhesive tape connects, and meanwhile, adhesive tape also has good leak tightness.
In order to improve leak tightness when this programme uses further, be coated with elastic sealant at back shroud 13 and the junction of front grid.
In sum, this programme adopts pair of lamina cavity structure, i.e. guide duct and the first cavity, guide duct and the first cavity are incline structure, and smooth connection, make the air flow energy flowing into grid flow into the admission port of air-conditioning assembly along dip plane, air-conditioning air intake resistance reduces greatly, improves the operating efficiency of air-conditioning.Adopt drainage plate and end face to be the rectangular tube of arcuate structure simultaneously, improve intake efficiency, effectively improve the operating efficiency of air-conditioning.
Mode above only by illustrating describes some one exemplary embodiment of the present invention, undoubtedly, for those of ordinary skill in the art, when without departing from the spirit and scope of the present invention, can revise described embodiment by various different mode.Therefore, above-mentioned accompanying drawing is illustrative with being described in essence, should not be construed as the restriction to the claims in the present invention protection domain.
