The air-conditioning duct 100 of rail vehicle 1000 according to an embodiment of the present invention, air-conditioner wind are described below with reference to Fig. 1-Fig. 7
Road 100 into the compartment of rail vehicle 1000 for blowing, and to adjust the temperature and air in compartment, air-conditioning duct 100 can be with
It is located at the top in compartment, for example, the two sides of the top cover in compartment can be located at, air-conditioning duct 100 can be along rail vehicle 1000
Length direction extends, and the length direction of air-conditioning duct 100 and the length direction of rail vehicle 1000 can be consistent.
As shown in Fig. 1-Fig. 7, air-conditioning duct 100 according to an embodiment of the invention have air inlet 103 and it is multiple go out
Air holes 104, air inlet 103 are suitable for being connected to the wind-supply unit of air-conditioning system, and exhaust vent 104 is used for compartment air feed.
Wherein, the air inlet 103 of air-conditioning duct 100 be set to air-conditioning duct 100 the first wall 101, air-conditioning duct 100 it is more
A exhaust vent 104 is set to the second wall 102 of air-conditioning duct 100, it is to be understood that multiple exhaust vents 104 are along air-conditioning duct 100
Length direction arrangement, the length direction of air-conditioning duct 100 can be consistent with the length direction in compartment, with to supplying everywhere in compartment
Wind.
Part in multiple exhaust vents 104 is located at the same position of 100 length direction of air-conditioning duct with air inlet 103,
That is the exhaust vent 104 of this part, adjacent to air inlet 103, the leeway out at this is larger.
Unhurried current plate 10 is equipped in air-conditioning duct 100, unhurried current plate 10 is oppositely arranged with the part exhaust vent 104, and flow slowly plate 10
It is spaced apart with the second wall 102, unhurried current plate 10 can be parallel to each other with the second wall 102, and the plate 10 that flows slowly has ventilation hole 11, unhurried current
Ventilation hole 11 on plate 10 is arranged in a staggered manner with exhaust vent 104, i.e. projection of the ventilation hole 11 on the second wall 102 and exhaust vent 104
It is staggered.
It is understood that the wind speed at the exhaust vent 104 being oppositely arranged with air inlet 103 is fast, pressure is big, setting unhurried current
After plate 10, the wind for blowing into air-conditioning duct 100 from air inlet 103 is kept off by 10 lattice of unhurried current plate, can not flow directly into exhaust vent 104, and
It is the gap between unhurried current plate 10 and the second wall 102 to be flowed by the ventilation hole 11 on unhurried current plate 10, then pass through from gap location
The exhaust vent 104 of the part flows to compartment.In some embodiments, the length of unhurried current plate 10 is not less than the length of air inlet 103,
The unhurried current effect of unhurried current plate 10 in this way is more stable.
Air-conditioning duct 100 according to an embodiment of the present invention can prevent from coming in from air inlet 103 by setting unhurried current plate 10
Air-flow be discharged directly from exhaust vent 104, it is possible thereby to reduce the air output at air inlet 103, avoid herein air quantity it is excessive
And cause lower section comfort poor, it is conducive to uniform outlet air.
In some embodiments, as shown in Figure 1 and Figure 4, the first wall 101 can be oppositely arranged with the second wall 102, such as the

To the distance of the first wall 101, narrow gap can be formed between the second wall 102 in unhurried current plate 10 in this way, the first wall 101,
Second wall 102 flowing plate 10 of easing up can be arranged in parallel.
As shown in Figure 3 and Figure 7, ventilation hole 11 can be the strip-shaped hole extended along 100 length direction of air-conditioning duct, some
In embodiment, ventilation hole 11 can be to be multiple, such as 4, and multiple ventilation holes 11 are set along 100 length direction interval of air-conditioning duct
It sets.Ventilation hole 11 and the part exhaust vent 104 (exhaust vent 104 blocked by unhurried current plate 10, in other words with 103 face of air inlet
Exhaust vent 104) be staggered along the width direction of the second wall 102, in this way, the molding of ventilation hole 11 is simple, and do not influence exhaust vent
104 uniform outlet air.
In one embodiment, as shown in Figure 3 and Figure 4, exhaust vent 104 can be round hole, the part exhaust vent 104
(exhaust vent 104 blocked by unhurried current plate 10, in other words with the exhaust vent 104 of 103 face of air inlet) is arranged in along the longitudinal direction
Two column, projection of the ventilation hole 11 on the second wall 102, which is located at, two to be listed between air holes 104, other outlet air to flow slowly outside plate 10
Hole 104 can be arranged in the matrix type of multiple rows of multiple row, with balanced outlet air.
In separately in one embodiment, and the part exhaust vent 104 (exhaust vent 104 blocked by unhurried current plate 10, in other words
With the exhaust vent 104 of 103 face of air inlet) adjacent to the outer edge setting of the second wall 102, air inlet 103 is adjacent to the second wall 102
Inside edge setting.Outer finger described herein is close to the side of vehicle exterior, the interior side referred in the middle part of compartment.
