Abstract
The utility model relates to a passenger car ventilating system, particularly the improved structure of the system, wherein an air suction opening is arranged on the facade of the passenger car and is communicated with a blower connected with a control switch, the blower is orderly communicated with a filter and an air duct provided with a plurality of air openings, the air duct is also communicated with a cold air duct of an air-conditioning system of the passenger car, and the rear part of the passenger car is provided with another blower communicated with an air outlet. The ventilating system not only can make use of inertia to carry out natural ventilation, but also can carry out forced ventilation through the blower and the utility model supplies fresh and clean air for passengers through the filter.
Description
The utility model relates to a kind of ventilation of passenger train system, and is especially relevant with the structure-improved of system.
Usually, the ventilation system of passenger vehicle can be divided into two kinds.A kind of is natural ventilation, and as offering the skylight on car roof, the inside and outside air of car can free in and out, and is convenient and swift, but air quantity can not regulate, and fresh air into the car do not filter, and dust amount is big in the air.Another kind is an induced ventilation, as the installing scavenger fan, utilizes electric power outside the dirty air exhaustion car in the car, or the outer fresh air of car is sucked in the car; Also can install two air-exhaust fans, a row one inhales ground work; But induced ventilation like this, the electric power degree of utilization is all very low, and still not filtration of air, and real is inadvisable.
The purpose of this utility model is: the structure-improved that a kind of ventilation of passenger train system is provided.
Ventilation of passenger train system improvement structure of the present utility model mainly is made of inlet scoop, blower fan, air channel and air outlet etc.The inlet scoop is opened on the car front, is connected with blower fan; Master cock is connected with blower fan, and blower fan communicates with filter, air channel again successively, and the air channel is provided with several air ports; The car body rear also is provided with blower fan in addition and communicates with air outlet.
The utility model inlet scoop is connected with the blower fan of and arranged on left and right sides, and two blower fans also communicate with filter, air channel successively.
The blower fan at the utility model car body rear is located at and arranged on left and right sides respectively, and communicates with the air outlet of both sides.
The utility model air channel also communicates with the cool-air duct of hvac system.
The utility model also can utilize the inertia of running car, and the fresh air outer car is pressed in the car, and the pressure that utilizes zone of negative pressure in the car again with the air exhaustion in the car, forms natural ventilation system greater than outside the car.
After adopting said structure, the utility model can not only utilize the car body inertia that travels, naturally ventilate, also can utilize the ventilation system induced ventilation as required, the control air quantity, and be provided with filter in the ventilation system of the present utility model, air filtration that can car is outer greatly reduces dust amount, makes the passenger breathe clean, pure and fresh air.In addition, the utility model also can be used as the defroster device of side window.
Below in conjunction with diagram and embodiment the utility model is further described.
Fig. 1 is the utility model ventilation system scheme drawing.
Consult Fig. 1, the utility model comprises members such as inlet scoop 1, blower fan 2, air channel 3 and air outlet 4.Inlet scoop 1 is opened in top, car front, is connected with left and right two blower fans 2 respectively; Two blower fans 2 are by master cock (not indicating among the figure) control, communicate with left and right air channel 3 respectively again, be provided with filter (not indicating among the figure) between blower fan 2 and the air channel 3, have air port 31 on the air channel 3, air channel 3 also communicates with the cool-air duct (not indicating among the figure) of a/c system; Car body rear zone of negative pressure also is provided with blower fan 2 and communicates with air outlet 4.
When vehicle ', because the inertia that travels, the outer air of car is pressed into inlet scoop 1, through blower fan 2 filters and air channel 3, is entered in the compartment by air port 31, supplies with the passenger; Discharge by car body rear fan 2 and air outlet 4 again, form natural ventilation system.When opening master cock, the blower fan 2 of top, car front is started working, and the force air that car is outer sucks inlet scoop 1, same through filter and air channel 3, supply with the passenger, and force air in the car is discharged from air outlet 4, form forced ventilation system by car body rear blower fan 2.
In addition, car door of the present utility model etc. locate also to be provided with air outlet, make whole ventilation system more perfect.
Claims (4)
1, the structure-improved of a kind of ventilation of passenger train system, mainly form by inlet scoop, blower fan, air channel and air outlet etc., it is characterized in that: the inlet scoop is opened in the car front, be connected with blower fan, master cock is connected with blower fan, and blower fan communicates with filter, air channel again successively, and the air channel is provided with several air ports, the air channel also communicates with the cool-air duct of hvac system, and the car body rear also is provided with blower fan in addition and communicates with air outlet.
2, ventilation of passenger train system improvement structure according to claim 1, it is characterized in that: the inlet scoop is connected with the blower fan of and arranged on left and right sides, and two blower fans also communicate with filter, air channel successively.
3, ventilation of passenger train system improvement structure according to claim 1, it is characterized in that: the blower fan at car body rear is located at and arranged on left and right sides respectively, and communicates with the air outlet of both sides.
4, ventilation of passenger train system improvement structure according to claim 1, it is characterized in that: the air channel communicates with the cool-air duct of hvac system.
