Abstract
The utility model discloses a static pressure air duct for a subway train, which belongs to the technical field of railway vehicle air conditioning system ventilation. The static pressure air duct for the subway train comprises an air inlet duct, a main air duct and static pressure air ducts on two sides of the main air duct; an air outlet is formed at the bottom end of each static pressure air duct; the air inlet duct is an acoustic air duct made of acoustic boards; an air quantity adjusting device arranged at the opening of the air inlet duct is canceled; and a main air duct drag plate perpendicular to wind direction is arranged in the main air duct. The static pressure air duct for the subway train has a simple structure, effectively eliminates noises produced by the air duct, reduces the resistance of the air duct, and reduces the impact and vibration on the air duct caused by a blower fan.
Description
Technical field
The utility model relates to subway train and uses the static pressure air channel, belongs to guideway vehicle a/c system aeration technology field.
Background technology
At present along with the development at full speed of the technology of railcar and the raising of living standards of the people, requirement to a/c system on the railcar is more and more higher, not only be satisfied with air-conditioning unit energy normal operation, can heat up and lower the temperature in the guest room, and the traveling comfort in the emphasis car, temperature field particularly, the homogeneity of moisture field and wind speed field, the requirement of the size of gentle breeze speed and ventilation system and supply air system noise etc., air-conditioning is most of at present adopts the static pressure air channel uniformly of blowing, but existing static pressure air channel is also in the further optimization and perfect that awaits aspect wind-dryness and the wind speed field.
The utility model content
Technical problem to be solved in the utility model is, overcomes the shortcoming of prior art, proposes a kind of subway train and uses the static pressure air channel, can effectively reduce wind-dryness, reduces the air channel windage.
In order to solve above technical matters, the utility model provides a kind of subway train to use the static pressure air channel, comprise wind inlet channel, air trunk and be positioned at the static pressure air channel of air trunk both sides, be provided with air outlet in bottom, described static pressure air channel, the sound-absorbing air channel that described wind inlet channel is made by abatvoix, well solved the problem of the noise of air-conditioning unit outlet, and cancellation is arranged on the volume adjusting apparatus of described wind inlet channel mouth; Be provided with the flaps vertical with wind direction in described air trunk, to increase the static air pressure power in the anterior air trunk, when making the air admission static pressure air channel of air trunk front end, the angle that becomes a mandarin is big, and the inlet air amount is also just more relatively.
The technical scheme that the utility model further limits is:
Aforesaid a kind of subway train is used the static pressure air channel, in described static pressure air channel, be provided with the static pressure air channel dividing plate vertical with wind direction, can prevent that air anterior in the static pressure air channel from flowing to the rear portion too much by actv., do not hinder the static balance effect of air again, can well improve air and go out to flow angle at the air outlet place.
The beneficial effects of the utility model are: (1) has cancelled volume adjusting apparatus, there are not mobilizable parts in the air channel, movable parts have been eliminated under sharp effect and the noise that produces, and reduced manufacturing cost, simultaneously for whole air channel, first section is the sound-absorbing air channel, has reduced propagation of noise; (2) air channel strengthens the characteristic adaptation ability of air-conditioning unit blower fan; (3) duct resistance is little, adopts this type air channel, and the pressure head of ventilating set can suitably reduce, and also can reduce simultaneously because the noise of the impact that the blower fan high-head brings to the air delivery duct, vibration generation.

The specific embodiment
Embodiment 1
A kind of subway train that present embodiment provides is used the static pressure air channel, structure such as Fig. 1 and Fig. 2 and shown in Figure 3, comprise wind inlet channel 1, air trunk 2 and be positioned at the static pressure air channel 3 of air trunk both sides, be provided with air outlet 4 in bottom, described static pressure air channel, the sound-absorbing air channel that described wind inlet channel 1 is made by abatvoix 7, in described air trunk 2, be provided with the air trunk flaps 5 vertical, in described static pressure air channel 3, be provided with the static pressure air channel dividing plate 6 vertical with wind direction with wind direction.
On the basis in original static pressure air channel, first section air channel of air-conditioning unit outlet is designed to common air channel, adopt sound insulating sheet material to make, as the sound-absorbing air channel; And just begin just to be designed to the static pressure air channel at second section, in the static pressure air channel, add simultaneously static pressure air channel dividing plate, can prevent that air anterior in the static pressure air channel from flowing to the rear portion too much by actv., do not hinder the static balance effect of air again, can well improve air and go out to flow angle at the air outlet place; Add the air trunk flaps in air trunk, to increase the static air pressure power in the anterior air trunk, when making the air admission static pressure air channel of air trunk front end, the angle that becomes a mandarin is big, and the inlet air amount is also just more relatively.
In addition to the implementation, the utility model can also have other embodiments.All employings are equal to the technical scheme of replacement or equivalent transformation formation, all drop on the protection domain of the utility model requirement.
Claims (2)
1. a subway train is used the static pressure air channel, comprise wind inlet channel, air trunk and be positioned at the static pressure air channel of air trunk both sides, be provided with air outlet in bottom, described static pressure air channel, it is characterized in that: the sound-absorbing air channel that described wind inlet channel is made by abatvoix, and cancel original volume adjusting apparatus that is arranged on described wind inlet channel mouth; In described air trunk, be provided with the air trunk flaps vertical with wind direction.
2. a kind of subway train according to claim 1 is used the static pressure air channel, it is characterized in that: be provided with the static pressure air channel dividing plate vertical with wind direction in described static pressure air channel.
