Abstract
The invention discloses an air flue of an air conditioner of a motor train unit. The air flue comprises an air flue body, wherein an air inlet is arranged at one end of the air flue body, a plurality of air outlets which are distributed at intervals are arranged at one side, facing toward the interior of a motor train, of the air flue body, the air flue further comprises a cavity separation board and a guide plate, wherein the cavity separation board is located in a channel body and a channel is divided into two cavities through the cavity separation board, the cavity, in which the air outlets are located, is a dynamic pressure cavity, and the other cavity is a static pressure cavity, the static pressure cavity at the air inlet is connected to an air outlet of an air conditioning system, a plurality of air outlets of the static pressure cavity which are distributed at intervals are arranged on the cavity separation board, the guide plate is arranged on the air outlets of the static pressure cavity, and insulated cotton is arranged on the surface of the air flue body, the surface of the cavity separation board and the surface of the guide plate. The air flue of the air conditioner of the motor train unit has the advantages of uniform air output, and good refrigeration effect and heating effect.
Description
Technical field
The present invention relates to a kind of air-conditioning duct, particularly a kind of motor train unit air-conditioning duct.
Background technology
Motor train unit air-conditioning duct operated by rotary motion, at the motor train unit train body top, is transported in guest room for the wind by a/c system.Existing a kind of motor train unit air-conditioning duct, contain the air channel body, and body one end in air channel is ventilation inlet, and ventilation inlet and a/c system air outlet interlink, and body side in car in air channel is provided with some air outlets spaced apart.While using above-mentioned motor train unit air-conditioning duct, owing to diminishing gradually flow process from the intrinsic air wind speed of ventilation inlet access passage, the air wind speed and the air quantity difference that therefore from the diverse location air outlet, are transported in guest room are large, cause air-out inhomogeneous.In addition, when the a/c system transporting cold-air, air-conditioning duct can be higher with temperature in guest room air generation interchange of heat and the air-conditioning duct temperature is raise, air-conditioning duct after the rising temperature again with air-conditioning duct in than cold air generation interchange of heat, make the cold air be transported in guest room higher than the cold air temperature in a/c system, cause refrigeration to be affected.When a/c system is carried heating installation, principle is identical, can affect its heating effect.
Summary of the invention
The technical problem to be solved in the present invention be to provide a kind of air-out evenly, refrigeration and the good motor train unit air-conditioning duct of heating effect.
For solving the problems of the technologies described above, a kind of motor train unit air-conditioning duct of the present invention, contain the air channel body, body one end in air channel is ventilation inlet, body side in car in air channel is provided with some air outlets spaced apart, also contain separate space plate and deflecting plate, described separate space plate is positioned at channel body and passage is separated into to two cavitys, the cavity at described air outlet place is called dynamic pressure cavity, another cavity is called the static pressure chamber, static pressure chamber and the a/c system air outlet at ventilation inlet place interlink, described separate space plate is provided with some static pressure chamber air outlets spaced apart, described static pressure chamber air outlet is provided with deflecting plate, described air channel body surface, separate space plate surface and baffle surface are equipped with heat-preservation cotton.
The sectional area in described static pressure chamber is 1/3rd of dynamic pressure cavity sectional area.
While using above-mentioned motor train unit air-conditioning duct, the air of a/c system output is from the static pressure chamber access passage body of ventilation inlet, by static pressure chamber air outlet, be transported in dynamic pressure cavity again, because static pressure chamber air outlet is provided with deflecting plate, through stopping of deflecting plate, air rate eases up, flow direction reaches unanimity, therefore when air is transported in guest room from the air outlet of channel body, air will more slowly and reposefully flow, thereby reach the uniform purpose of air-out.Because described air channel body surface, separate space plate surface and baffle surface are equipped with heat-preservation cotton, therefore can greatly reduce the air-conditioning duct temperature change that in air-conditioning duct and guest room, air generation interchange of heat causes, thereby reduce the air temperature variations of a/c system output, therefore can improve refrigeration and heating effect.Heat-preservation cotton can also play the effect of sound insulation and noise reduction simultaneously.

The structural representation that Fig. 1 is a kind of motor train unit air-conditioning duct of the present invention.
The A-A enlarged view that Fig. 2 is Fig. 1.
The B-B enlarged view that Fig. 3 is Fig. 1.
The I part enlarged drawing that Fig. 4 is Fig. 2.
1. ventilation inlets in figure, 2. air channel body, 3. air outlet, 4. static pressure chamber, 5. separate space plate, 6. dynamic pressure cavity, 7. static pressure chamber air outlet, 8. deflecting plate, 9. heat-preservation cotton.
the specific embodiment
In Fig. 1 to Fig. 4, a kind of motor train unit air-conditioning duct of the present invention, contain air channel body 2, body 2 one ends in air channel are ventilation inlet 1, air channel body 2 side in car is provided with some air outlets spaced apart 3, also contain separate space plate 5 and deflecting plate 8, described separate space plate 5 is positioned at channel body 2 and passage is separated into to two cavitys, the cavity at described air outlet 3 places is called dynamic pressure cavity 6, another cavity is called static pressure chamber 4, static pressure chamber 4 and the a/c system air outlet 3 at ventilation inlet 1 place interlink, described separate space plate 5 is provided with some static pressure chamber air outlets 7 spaced apart, described static pressure chamber air outlet 7 is provided with deflecting plate 8, body 2 surfaces, described air channel, separate space plate 5 surfaces and deflecting plate 8 surfaces are equipped with heat-preservation cotton 9.The sectional area in described static pressure chamber 4 is 1/3rd of dynamic pressure cavity 6 sectional areas.While using above-mentioned motor train unit air-conditioning duct, the air of a/c system output is from the static pressure chamber 4 access passage bodies 2 of ventilation inlet 1, by static pressure chamber air outlet 7, be transported in dynamic pressure cavity 6 again, because static pressure chamber air outlet 7 is provided with deflecting plate 8, through stopping of deflecting plate 8, air rate eases up, flow direction reaches unanimity, therefore when air is transported in guest room from the air outlet 3 of channel body 2, air will more slowly and reposefully flow, thereby reach the uniform purpose of air-out.Because body 2 surfaces, described air channel, separate space plate 5 surfaces and deflecting plate 8 surfaces are equipped with heat-preservation cotton 9, therefore can greatly reduce the air-conditioning duct temperature change that in air-conditioning duct and guest room, air generation interchange of heat causes, thereby reduce the air temperature variations of a/c system output, therefore can improve refrigeration and heating effect.Heat-preservation cotton 9 can also play the effect of sound insulation and noise reduction simultaneously.
