< the first example >
[a/c system]
As shown in Figure 1, in order to regulate temperature and humidity of the compartment 2a that is positioned at vehicle 2 etc. and vehicle 2 possesses a/c system 1.A/c system 1 possesses interior environment system 3, air-conditioning duct 4, rectification campaign member 5 and velocity of flow adjust plate 6 substantially.Interior environment system 3 is arranged at the top of roof structure body 7 to be positioned at the form of middle body of fore-and-aft direction, be formed as supplying with the structure of air-conditioner wind.In roof structure body 7, be provided with a pair of air-conditioning duct 4 in symmetric configuration again.In addition, left and right air-conditioning duct 4 has identical structure except each structure is in symmetric configuration.Therefore, below, only illustrate the air-conditioning duct (air-conditioning duct on right side) 4 of a side, and omit explanation and the diagram of the air-conditioning duct of opposite side.
[air-conditioning duct]
Air-conditioning duct 4 is members of essentially rectangular tubular, extends to rear end from the front end of vehicle 2.In air-conditioning duct 4, be provided with dividing plate (not shown) at fore-and-aft direction middle body, air-conditioning duct 4 is divided into two on fore-and-aft direction by this dividing plate.By being divided into two like this, be formed with respectively air flue 4a with this front side and rear side at dividing plate in air-conditioning duct 4.This air flue 4a extends on fore-and-aft direction, and it is rectangular-shaped to be formed as cross section, is single shape., air-conditioning duct 4 is formed as only having therein as the air flue 4a of air trunk and does not have the structure in the secondary air channel in the air-conditioning duct of structure of pumping chamber's mode.Therefore, there is not the spaced walls portion that separates as prior art air trunk and secondary air channel, therefore do not need the correction of the shape of carrying out spaced walls portion, easily manufacture.
Be formed as like this air flue 4a of single shape with respect to configuration symmetrically before and after dividing plate, there is identical structure.Therefore, below only illustrate the air flue 4a of a side, and omit explanation and the diagram of the air flue of opposite side.The air flue 4a forming is like this connected with interior environment system 3.
Interior environment system 3 is arranged on the roof structure body of vehicle 2, and configures accordingly with each air flue 4a.In this example, each vehicle 2 is formed with four air flue 4a, and therefore each vehicle 2 has four interior environment systems 3.Interior environment system 3 is formed as supplying with the structure of air-conditioner wind, and centralized configuration is at the fore-and-aft direction central portion of vehicle 2.Interior environment system 3 and air flue 4a are connected on distolateral at one of the air flue 4a as bulkhead sides, and are supplied to herein the air-conditioner wind that comes from interior environment system 3.By means of this, in air flue 4a, form the flowing of air-conditioner wind that is positioned at the direction of the other end in fore-and-aft direction outside from this one end side direction.
Again, on air-conditioning duct 4, on the overall width direction Outboard Sections of its bottom, be formed with upward recessed mounting groove 4b, on the top of this mounting groove 4b, be formed with the multiple blow-off outlet 4c that connect air flue 4a and compartment 2a.It is upwardly extending slot-shaped that blow-off outlet 4c is formed as front and back, on fore-and-aft direction uniformly-spaced to configure.In mounting groove 4b, be provided with rectification campaign member 5 again.
[rectification campaign member]
Rectification campaign member 5 is as shown in Figure 3 for example by light alloy section bar or FRP(Fiber Reinforced Plastic, fiber-reinforced plastic) member of cross section U-shaped that forms extends on fore-and-aft direction.Rectification campaign member 5 is embedded in mounting groove 4b so that opening portion 5a is arranged in the form of below.On the top section of rectification campaign member 5, be formed with multiple hole 5b that blow out.As first blow out hole blow out upwardly extending slot-shaped hole, 5bShi front and back, hole, the width h1 of its left and right directions is narrower than the width h2 of the left and right directions of opening portion 5a.Again, the form that blows out hole 5b at the upper surface of rectification campaign member 5 with encirclement is provided with spongiform containment member 8.Containment member 8 is clipped between rectification campaign member 5 and air-conditioning duct 4, and seals between them with the form being connected with the blow-off outlet 4c that blows out hole 5b and air-conditioning duct 4.
In rectification campaign member 5, be provided with multiple rectification campaign plates 9 again.Rectification campaign plate 9 is outstanding downwards from the end face of rectification campaign member 5, and the form that blows out hole 5b to be horizontally through is extended on left and right directions.Rectification campaign plate 9, to be uniformly-spaced configured on rectification campaign member 5, is configured to louver shape.By means of this, in the opening portion 5a of rectification campaign member 5, be formed with the hole 5c(second that blows out long on left and right directions and blow out hole).By means of this, rectification campaign member 5 is formed as having the upwardly extending slot-shaped hole 5b that blows out in front and back at upside, and has the dual structure that blows out hole 5c long on left and right directions at downside.
The rectification campaign member 5 like this with dual structure limits by the hole 5b that blows out of upside the air quantity blowing out from here, is designated hereinafter simply as " downside blows out hole 5c " by the hole 5c(that blows out of downside) the hole 5b(that blows out from upside is designated hereinafter simply as to " upside blows out hole 5b ") direction of the air-conditioner wind that blows out changes into the direction to vertical lower.Further describe particularly about flowing of air-conditioner wind: in the air flue 4a of air-conditioning duct 4, mobile air-conditioner wind is directed into upside by blow-off outlet 4c and blows out hole 5b.Blow-off outlet 4c and upside blow out hole 5b and are all formed as slot-shapedly, and therefore air-conditioner wind blows out hole 5b from upside and blows out to have the state of speed composition of fore-and-aft direction.Upside blow out hole 5b below, the space wider than its width is formed between adjacent rectification campaign plate 9, can air-conditioning wind direction left and right directions be blown out diffusely by this space.In addition, blow out from upside the air-conditioner wind that hole 5b blows out and contact with rectification campaign plate 9, can make it flow towards vertical lower with this.Like this, by the use member 5 of rectifying the incorrect style of work, can make the air-conditioning wind direction left and right directions diffusion blowing out from air-conditioning duct 4 and it is flowed towards vertical lower.
[hampering plate]
Again, on air-conditioning duct 4, under the top of its mounting groove 4b and interior environment system 3 (particularly, one of air flue 4a distolateral part) be provided with hampering plate 10.This hampering plate 10 is the board members at the upwardly extending strip in front and back, and to be clipped in the form setting between top and the containment member 8 of mounting groove 4b.On hampering plate 10, be formed with the gap 10a narrower than blow-off outlet 4c width, gap 10a throttling is directed into upside and is blown out the air-conditioner wind of hole 5b by blow-off outlet 4c.In addition, in this example, the width of gap 10a is the half degree of the width of blow-off outlet 4c, but is not limited to this width.
[velocity of flow adjust plate]
In the air flue 4a of air-conditioning duct 4, be provided with velocity of flow adjust plate 6 again.Be so-called tabular net member (for example aperture opening ratio is more than 80% web plate) as the velocity of flow adjust plate 6 of velocity of flow adjust member, there is the frame 6a with the roughly the same shape in cross section of air flue 4a.Velocity of flow adjust plate 6 stands vertically and is embedded in air flue 4a, hinder the flowing of fore-and-aft direction of mobile air-conditioner wind in air flue 4a and reduce speed composition (being designated hereinafter simply as " flow velocity of fore-and-aft direction ") and the pressure of fore-and-aft direction in the flow velocity of air-conditioner wind, apply resistance and reduce flow velocity and the pressure of fore-and-aft direction to air-conditioner wind.
The velocity of flow adjust plate 6 forming is like this arranged in air flue 4a with the position that is supplied to the air-conditioner wind that comes from interior environment system 3 (, interior environment system 3 under) and compares near on the position in downstream.More specifically, velocity of flow adjust plate 6 is, for the distance L between one end and the other end of air flue 4a, in the setting area below the above L/3 of the described one end L/10 of distance, to dispose velocity of flow adjust plate 6.On this setting area, the flow velocity of the fore-and-aft direction of air-conditioner wind is compared with pressure drop large and air-conditioner wind compared with other region.Therefore, come from the air quantity of the downside blow-off outlet 5c that is positioned at setting area less than the downside blow-off outlet 5c that is positioned at other regions.Setting area configuration velocity of flow adjust plate 6 by such, with this can suppress air-conditioner wind fore-and-aft direction flow velocity and improve the pressure of air-conditioner wind, can increase the air quantity that comes from the downside blow-off outlet 5c that is positioned at setting area.In addition, for example, length in the vehicle lengthwise direction of air-conditioning duct 4 is 19.14m, the setting position of velocity of flow adjust plate 6 is preferably configured in apart near position 2m before and after the center of interior environment system 3, as long as but being arranged on the position of the pressure drop of air-conditioner wind, the setting position of velocity of flow adjust plate 6 is that the various factors such as size and the quantity of interior environment system based on air-conditioning duct regulates.
Again, come from the air quantity of downside blow-off outlet 5c corresponding to the flow velocity of the fore-and-aft direction of mobile therein air-conditioner wind, aforementioned flow velocity is larger, and the air quantity that comes from downside blow-off outlet 5c is less.In setting area, in the position of the flow velocity maximum of the fore-and-aft direction of air-conditioner wind, i.e. aforementioned air quantity minimum in the high speed position of the flow velocity maximum of the fore-and-aft direction of mobile air-conditioner wind in air flue 4a.Therefore, be preferably suppressed at the flow velocity of the fore-and-aft direction of the air-conditioner wind in this high speed position, preferably near the downstream configuration velocity of flow adjust plate 6 high speed position.Therefore,, in this example, near the downstream high speed position disposes velocity of flow adjust plate 6.
[function of a/c system]
Below, further illustrate the function of a/c system 1 with reference to Fig. 5.Fig. 5 illustrates that the downside configuring respectively from one end to the other end of air flue 4a blows out the wind speed (longitudinal axis) that 5cXiang compartment, hole 2a blows out, and each numbering (transverse axis) is to blow out hole 5c from the downside of the other end of the most close air flue 4a to start to indicate successively.That is, it is No. 1 that the downside of the other end of the most close air flue 4a blows out hole 5c, and be positioned at air flue 4a one end, be positioned at interior environment system 3 under downside to blow out hole 5c be No. 43.Again, the histogram of black illustrates and blows out from each downside the wind speed that hole 5c blows out in the situation that is provided with hampering plate 10 and velocity of flow adjust plate 6 as a/c system 1, and the histogram of white is illustrated in and blows out from each downside the wind speed that hole 5c blows out in the situation that is not provided with hampering plate 10 and velocity of flow adjust plate 6 in a/c system 1.
As can be seen from Figure 5, interior environment system 3 to its under (direction of the supply) supply with air-conditioner wind, therefore in the situation that not being provided with hampering plate 10, from be positioned at interior environment system 3 under downside blow out No. 5c(42, hole and No. 43) directly blow out air-conditioner wind, the wind speed that the wind speed of the air-conditioner wind blowing out from here blows out hole 5c than other downside increases relatively highlightedly.With respect to this, in a/c system 1, be positioned at interior environment system 3 under downside blow out No. 5c(42, hole and No. 43) on be provided with hampering plate 10, by these hampering plate 10 throttlings from be positioned at interior environment system 3 under downside blow out No. 5c(42, hole and No. 43) amount that blows out.By means of this, the downside that restriction is positioned under interior environment system 3 blows out hole No. 5c(42 No. 43) air quantity, can improve the homogeneity that blows out the wind speed profile of the air-conditioner wind that hole 5c blows out from each downside.
Again, with whether have hampering plate 10 independently, under interior environment system 3, a part for air-conditioner wind not from be positioned at interior environment system 3 under downside blow out hole 5c and blow out but recoil at the lower surface of air-conditioning duct 4, be positioned at interior environment system 3 under the locational nearest region in tight downstream on, the air-conditioner wind of this recoil is towards the top of air-conditioning duct 4 to the other end side flow of air flue 4a.On this nearest region, because recoil air-conditioner wind is in turbulence state, again, it flows to towards top, therefore on nearest region, blows out No. 5c(40, hole and No. 41 from being positioned at the downside of interior environment system 3 sides) air quantity that blows out extremely declines.In addition,, on nearest region, because air-conditioner wind is in turbulence state, therefore other regions of the velocity ratio of its fore-and-aft direction are large.Except the larger downside of the composition of top-direction blows out No. 5c(40, hole and No. 41), from respectively blowing out air quantity that hole 5c the blows out flow velocity corresponding to the fore-and-aft direction of air-conditioner wind.Therefore, in the situation that not being provided with hampering plate 10 and velocity of flow adjust plate 6, blowing out hole No. 5c(36 to No. 41 from what be positioned at nearest region) wind speed of the air-conditioner wind that blows out is less than other and blows out the wind speed of hole 5c relatively, near the downside flow velocity of its fore-and-aft direction high speed position the most at a high speed blows out hole No. 5c(36) upper minimum.
With respect to this, in a/c system 1, velocity of flow adjust plate 6 is arranged near aforementioned high speed position and its downstream (between No. 35 and No. 34), therefore can hinder the flowing of air-conditioner wind in high speed position and suppresses flow velocity and the pressure drop of the air-conditioner wind on high speed position and upstream side thereof.By means of this, the downside that can increase from being positioned at nearest region blows out hole No. 5c(36 to No. 41) air quantity that blows out of the wind speed of the air-conditioner wind that blows out and regulating excessive and not enough.
Again, velocity of flow adjust plate 6 has rectification function, and formed turbulent flow is carried out to rectification.Because air-conditioner wind blows out hole No. 5c(36 to No. 41 in turbulence state to the downside being positioned on aforementioned nearest region) delivery volume in not enough state, as mentioned above by rectification air-conditioner wind, with this can increase this delivery volume and increase from the locational downside on aforementioned side blow out hole No. 5c(36 to No. 41) the wind speed of air-conditioner wind.
In a/c system 1, the downside that can increase from being positioned at nearest region blows out hole No. 5c(36 to No. 41 like this) wind speed of the air-conditioner wind that blows out, can suppress again from be positioned at interior environment system 3 under downside blow out the wind speed of the air-conditioner wind that hole 5c blows out.By means of this, can improve the homogeneity that blows out the wind speed profile of the air-conditioner wind that hole 5c blows out from each downside.
Again, in air flue 4a, its other end is plugged, and the air-conditioner wind of therefore coming from upstream flow recoils at the other end.Not being provided with in the structure of velocity of flow adjust plate 6, air-conditioner wind in the situation that maintaining flow velocity with the other end collision of air flue 4a and recoil.Therefore, the pressure of the air-conditioner wind on the other end of air flue 4a improves, and blows out 5c(1～No. 15, hole from being positioned near the locational downside of the other end of air flue 4a) wind speed of the air-conditioner wind that blows out increases relatively.With respect to this, in a/c system 1, be suppressed at than velocity of flow adjust plate 6 flow velocity of mobile air-conditioner wind on the position near downstream by the valve action of velocity of flow adjust plate 6, thereby can stablize near the flowing other end of air flue 4a.By means of this, can suppress the pressure rise of air-conditioner wind, can suppress to blow out 5c(1～No. 15, hole from being positioned near the locational downside of the other end of air flue 4a) air-conditioner wind that blows out.Therefore, be suppressed at the inhomogeneity of the velocity flow profile of air-conditioner wind mobile in air flue 4a, can further improve the homogeneity that blows out the wind speed of the air-conditioner wind that hole 5c blows out from each downside.
[other structures]
Again, on the left and right directions outside of air-conditioning duct 4, be provided with the upwardly extending light equipment 11 in front and back, further on outside, dispose side top board 12 at it.Again, the form with the left and right directions central portion that is positioned at vehicle 2 between a pair of air-conditioning duct 4 is provided with cross flow fan 13(blowing engine), air-conditioner wind is also blown out to compartment 2a by this cross flow fan 13.Be provided with another rectification campaign member 14 at the downside of cross flow fan 13 again.This rectification campaign member 14 is tabular members, and to cover the form setting of cross flow fan 13 from below.This rectification campaign member 14 has multiple rectification campaign plates 16 at its lower surface.
Rectification campaign plate 16 extends on fore-and-aft direction, oliquely downward outstanding in the outside to left and right direction of lower surface of rectification campaign member 14.The rectification campaign plate 16 with such shape is arranged and configuration respectively on left and right directions, is configured to louver shape.On rectification campaign member 14, between adjacent rectification campaign plate 16, be formed with respectively the slot-shaped hole 14a that blows out again.Again, blow out hole 14a between adjacent rectification campaign plate 16 fore-and-aft direction across spacing parallel arranging setting.The air-conditioner wind that comes from cross flow fan 13 is blown out hole 14a and is blown out to compartment 2a by this, and its direction is changed into outside direction oliquely downward to left and right direction by rectification campaign plate 16.
The a/c system 1 forming is like this only for using the inner air-conditioning duct 4 that is unitarily formed air flue 4a, and near this external high speed position and the structure of its downstream configuration velocity of flow adjust plate 6, therefore number of components is few, and simple in structure.Therefore, compared with the a/c system of pumping chamber's mode, a/c system 1 easy to manufacture, its low cost of manufacture, can realize lightweight in addition.
< the second example >
A/c system 1 structure of the a/c system 1A of the second example and the first example is similar.Below, about the structure of the a/c system 1A of the first example, the only difference of explanation and the same structure of the a/c system 1 of the first example, about identical point, the description thereof will be omitted.Also be same about the a/c system 1B of the 3rd example.
The air-conditioning duct 4A of a/c system 1A has slot-shaped blow-off outlet 4c at lower surface as shown in Figure 6 to 8.Be provided with containment member 8A at the lower surface of air-conditioning duct 4A with the form of surrounding blow-off outlet 4c again.The below of this external air-conditioning duct 4A is releasably provided with rectification campaign member 5A.
[rectification campaign member]
Rectification campaign member 5A is two members that rectification campaign member 5,14 forms integratedly of the first example.Rectification campaign member 5A have be formed as before and after and the upwardly extending rectangular-shaped tabular planar portions 5d of right and left.Planar portions 5d is located on these two light equipments 11 to ride at the formal scheme between two light equipments 11 of the left and right sides, covers air-conditioning duct 4A and cross flow fan 13 from below.On planar portions 5d, near the both ends of left and right directions, blow out hole 5b to be formed with slot-shaped upside with the overlapping form of blow-off outlet 4c.Form by the form with overlapping, blow out the form configuration of hole 5b with this containment member 8A to surround upside, blow-off outlet 4c blows out hole 5b with upside and is connected by the endoporus of containment member 8A.Again, on planar portions 5d, what be formed with essentially rectangular shape at the middle body of left and right directions blows out window 5e, blows out window 5e and blows out the air-conditioner wind that comes from cross flow fan 13 from this.In addition, planar portions 5d has multiple rectification campaign plate 9A at its lower surface.
Rectification campaign plate 9A is the upwardly extending tabular component of right and left, hangs down and establishes to the outstanding form of vertical lower with the lower surface from planar portions 5d.Rectification campaign plate 9A on fore-and-aft direction with alignment arrangements uniformly-spaced.The rectification campaign plate 9A of configuration extends with linearity from left end to the right-hand member of planar portions 5d like this, forms to cross the form that blows out window 5e that upside on the two ends, left and right that are formed at respectively planar portions 5d blows out hole 5b and be formed at central portion.By configuring like this rectification campaign plate 9A, rectification campaign member 5 taking this can make to rectify the incorrect style of work member 5A and the first example is identically formed as dual structure, can make come from the air-conditioning wind direction left and right directions diffusion of blow-off outlet 4c and cross flow fan 13 and it is flowed downward.
