Abstract
The invention discloses a kind of railcar water conservancy diversion air-supply structure, air outlet is offered on lower cover plate, and a static pressure cavity is enclosed between deflector lower end surface and lower cover plate；The cross section of deflector includes the plane being connected smoothly and curved surface, and the curved surface of deflector will enter the both ends in the guiding of the wind in air duct air duct, offer sound-absorption hole on curved surface, offer air outlet in the plane of deflector.Enter the wind in air duct from upper cover plate air inlet, the both ends in air duct are not only flowed under the action of deflector, static pressure chamber is also entered by the air outlet on deflector, the wind for being sent into static pressure chamber is converted into static pressure by dynamic pressure, guest room is sent by the air outlet on the lower cover plate of air duct again, air-supply is increased in the compartment of unit lower part in this way, improves the uniformity in vehicle wind speed field and temperature field.
Description
Technical field
The present invention relates to track train air-conditioning ventilation system technical field, especially a kind of railcar water conservancy diversion air-supply knot
Structure.
Background technique
Air conditioner of subway vehicle unit is sent, there are mainly three types of air return methods at present, before preceding air-supply under return air, preceding air-supply return air and
Return air under lower air-supply.These three send, in air return method at present, using the mode of more generally lower lower return air of blowing.For
Difference send, the matched air delivery duct structure of the air-conditioner set of air return method institute also little identical, the flow-guiding structure difference inside air duct
Also relatively large.
For the air-conditioner set of return air under lower air-supply, the usually matched air delivery duct of institute uses static pressure type air duct, send with unit
Flow-guiding structure is set inside the first segment air duct of air port connection, the wind that unit is sent out is led to air duct both sides, due to first segment wind
Flow-guiding structure is provided with inside road, air outlet is not opened in this existing section air duct lower part, i.e. unit lower part is not provided with air-supply, such as
Shown in Fig. 1, this causes the uniformity in vehicle wind speed field and temperature field poor, reduces the comfort of passenger.
Summary of the invention
The technical problem to be solved by the present invention is to not set this problem of blowing for above-mentioned prior art unit lower part, and mention
For the railcar water conservancy diversion air-supply structure after a kind of improvement structure.
In order to solve the above technical problems, the technical solution adopted by the present invention is that:
A kind of railcar water conservancy diversion air-supply structure, including air duct, deflector are fixed on the side wall of air duct, and the air duct includes
Upper cover plate and lower cover plate offer air inlet on upper cover plate, it is characterised in that: air outlet are offered on lower cover plate, under deflector
A static pressure cavity is enclosed between end face and lower cover plate；The cross section of deflector includes the plane being connected smoothly and song
Face, the curved surface of deflector will enter the both ends in the guiding of the wind in air duct air duct, offer air outlet in the plane of deflector.
Deflector is fixed on upper cover plate using the pattern of riveting, improving deflector is to set in air duct,
A difference in height is formed between deflector and air duct lower cover plate, the cavity of formation is static pressure chamber.Under deflector plane and air duct
Air port is outputed on cover board, the size of air outlet determines that the wind that air-conditioner set is sent out is by leading with size according to air-flow simulation calculation
Flowing plate water conservancy diversion, a part are sent to air duct front and rear ends, and another part is sent to deflector and air duct by the air outlet on deflector
Static pressure chamber between lower cover plate, the wind for being sent into static pressure chamber is converted into static pressure by dynamic pressure, then is sent by the air outlet in air channel base plate
Enter guest room, such unit lower part increases air-supply in compartment, improves the uniformity in vehicle wind speed field and temperature field.
In order to reduce air-supply noise, sound-absorbing material is posted on deflector and air duct side wall, guarantees that the wind for being sent into guest room is
Low noise.
The present invention is sticked sound-absorbing material on deflector and air duct side wall, can further reduce noise.Preferably, institute
Stating sound-absorbing material is EPDM hole-opening foaming material, and joint does protective treatment, prevents from falling off.
Preferably, the facing the wind side of deflector curved surface is fixedly installed multiple guide vanes, plays preferable guide functions, more
Be conducive to organize the air stream of rule.
The present invention with the above structure, it has the following technical effect that
Deflector is arranged on the upper cover plate in air duct the present invention, and the lower cover plate in deflector and air duct forms a static pressure
Chamber enters the wind in air duct from upper cover plate air inlet, and the both ends in air duct are not only flowed under the action of deflector, also pass through deflector
On air outlet enter static pressure chamber, the wind for being sent into static pressure chamber is converted into static pressure by dynamic pressure, then passes through the outlet air on the lower cover plate of air duct
Mouth feeding guest room, such unit lower part increases air-supply in compartment, improves the uniformity in vehicle wind speed field and temperature field.Yin Ben
Invention posts sound absorber on deflector and air duct side wall, it can be ensured that the wind for being sent into guest room is low noise, the present invention
It provides and integrates water conservancy diversion, sound-absorbing, the railway vehicle air duct device for distributing air quantity.
Detailed description of the invention
Fig. 1 is water conservancy diversion air-supply structure schematic diagram in the prior art.
Fig. 2 is a kind of schematic diagram of railcar water conservancy diversion air-supply structure of the present invention.
Fig. 3 is the structural schematic diagram that air outlet is opened up in deflector plane.
Specific embodiment
In conjunction with the accompanying drawings, the present invention is further explained in detail.These attached drawings are simplified schematic diagram, only with
Illustration illustrates basic structure of the invention, therefore it only shows the composition relevant to the invention.
As shown in Fig. 2, a kind of railcar water conservancy diversion air-supply structure of the present invention, deflector 2 are fixed on the side wall of air duct,
The air duct includes upper cover plate and lower cover plate, and air inlet is offered on upper cover plate, offers air outlet on lower cover plate, under deflector
A static pressure cavity 1 is enclosed between end face and lower cover plate；The cross section of deflector include the plane that is connected smoothly and
Curved surface, the curved surface of deflector will enter the both ends in the guiding of the wind in air duct air duct, offer air outlet 3 in the plane of deflector.
Sound-absorbing material, sound-absorbing material EPDM hole-opening foaming material are posted on deflector and air duct side wall in the present embodiment.
