The specific embodiment
Below in conjunction with the accompanying drawing and the specific embodiment the utility model is described in further detail:
As shown in Figure 1, a kind of rolling stock air-conditioning duct structure comprises air channel main body 1; Air channel main body 1 is arranged at the top of car inside ceiling panel 2, and air channel main body 1 is along the elongated setting of length over ends of body direction, and car inside ceiling panel 2 is provided with the air outlet 3 that is used in the compartment, blowing; One end of air channel main body 1 is connected with the air outlet (not shown) of air-conditioning unit indoor set; Air through after the processing of air-conditioning unit evaporator gets into air channel main body 1 through air outlet, is sent in the compartment through air outlet 3, to regulate ambient temperature and the humidity in the compartment again; Be tightly connected between the bottom of air channel main body 1 and the car inside ceiling panel 2, form the leak free air flowing access.In order to reduce the noise of air-supply, the housing of air channel main body 1 adopts composite board material.
Along with the raising of running velocity, also increasingly high to the requirement that reduces noise, as shown in Figure 1 in order to reduce noise in the car, the bottom of main body 1 is provided with one deck air-supply plate 4 in the air channel, between air-supply plate 4 and car inside ceiling panel 2, one deck sound absorbing layer 5 is set again.Air-supply plate 4 and sound absorbing layer 5 are divided into wind pushing cavity 6, static pressure chamber 7 and distribution cavity 8 from top to bottom with the inner space of air channel main body 1.
Wherein, in order to make air-supply evenly, in the present embodiment, air-supply plate 4 adopts AND DEWATERING FOR ORIFICE STRUCTURE, and along the elongated setting of length over ends of body direction, satisfies the homogeneity of vehicle lengthwise direction air-supply, thereby satisfies the requirement of the car load length direction temperature difference less than 2 degree.On air-supply plate 4, evenly be provided with several exhaust vents 9, the exhaust vent 9 preferred circular ports that adopt, exhaust vent 9 forms the opening that the air in the air channel main body 1 is guided to the air outlet 3 on the car inside ceiling panel 2.
As shown in Figure 1, in order to regulate air output, be provided with the air quantity regulating mechanism that is used to regulate air output at each exhaust vent 9 place; In the present embodiment, to shown in Figure 6, the air quantity regulating mechanism comprises lining 10 and blanking cover 11 like Fig. 3; Lining 10 is fixed on the air-supply plate 4 at exhaust vent 9 places; Blanking cover 11 detachably is installed in lining 10, and blanking cover 11 is used for shutoff exhaust vent 9, and blanking cover 11 fixes in lining 10 through rotation.According to the requirement of air output, selection needs the quantity of the exhaust vent 9 of shutoff, and then regulates required air output.Lining 10 adopts anti-flaming ABS material with blanking cover 11.
As depicted in figs. 1 and 2, corresponding with air-supply plate 4, sound absorbing layer 5 satisfies the requirement of whole vehicle interior noise along the elongated setting of length over ends of body direction.Sound absorbing layer 5 is made up of framework 12 and several abatvoixs 13; Framework 12 is fixed on the inwall of air channel main body 1; Each exhaust vent 9 on the corresponding air-supply plate 4 is provided with an abatvoix 13, and abatvoix 13 is fixed on the framework 12, because sound absorbing layer 5 adopts tower structure; And dispersed placement between each abatvoix 13, so the space between each abatvoix 13 just forms the opening that the air in the air channel main body 1 is guided to the air outlet 3 on the car inside ceiling panel 2.The shape of abatvoix 13 and exhaust vent 9 shapes are complementary and also adopt circle, and the somewhat larger in diameter of abatvoix 13 is in the diameter of exhaust vent 9.The framework 12 of sound absorbing layer 5 adopts anti-flaming ABS material, and abatvoix 13 adopts the acoustical cotton material to process.Abatvoix 13 is provided with over against exhaust vent 9, in to the air-flow absorbing sound and lowering noise that is come out by exhaust vent 9, air-flow is also played the effect of reflection; The speed of air-flow is reduced; Air-flow is able to redistribution, and then forms the effect in static pressure chamber at this layer, reaches the purpose of static pressure air-supply.Because static pressure air channel structure of the prior art has been omitted in the setting of sound absorbing layer 5, not only material cost reduces, and can effectively reduce the height of air channel main body 1, reduces taking up room of air channel main body 1.
For making air-supply more even, as shown in Figure 1, the air outlet of car inside ceiling panel 2 adopts the wind pushing hole plate structure along the elongated setting of length over ends of body direction.The crooked arcuate structure in mind-set both sides more helped distribution of air flow during air-supply orifice plate on the car inside ceiling panel 2 was served as reasons, and improved the comfort level in compartment.
Air through after the processing of air-conditioning unit evaporator gets into the wind pushing cavity 6 of air channel main body 1 through the air outlet of indoor set, and several exhaust vents 9 that air-flow passes on the air-supply plate 4 flow out, and the air-flow of outflow blows to the sound absorber 13 of corresponding exhaust vent 9 belows setting; Sound absorber 13 plays the effect of reflection to the air-flow of producing by boasting in to the air-flow absorbing sound and lowering noise that is come out by exhaust vent 9, the speed of air-flow is reduced; Dynamic pressure converts static pressure to; Air-flow is able to redistribution, and then forms static pressure chamber 7 in the space above sound absorbing layer 5, reaches the purpose of static pressure air-supply; Air-flow through the reflection of sound absorbing layer 5 sound-absorbings passes the framework 12 of sound absorbing layer 5 and the space between the abatvoix 13; Get into the distribution cavity 8 of below, be sent in the compartment through the air outlet on the car inside ceiling panel 23 again, to regulate ambient temperature and the humidity in the compartment.
As stated, in conjunction with accompanying drawing and the given scheme content of embodiment, can derive the similar techniques scheme.In every case be the content that does not break away from the utility model technical scheme, to any simple modification, equivalent variations and modification that above embodiment did, all still belong in the scope of the utility model technical scheme according to the technical spirit of the utility model.
