Rail vehicle and its air intake device

Abstract

The invention discloses an air inlet device of a railway vehicle. The air inlet device comprises an air inlet way body externally arranged on the top of the vehicle, the lower portion of the air inletway body communicates with an air conditioner air inlet, and end portion air inlets are formed in the two ends, in the vehicle running direction, of the air inlet way body. Flow guiding plates are arranged in the air inlet way body. When the vehicle advances, airflow enters the air inlet way body from the end portion air inlet located in the front end and pushes the flow guiding plates to move sothat the end portion air inlet located in the rear end can be shielded, and the end portion air inlet located in the front end conducts the air conditioner air inlet. Top air inflow is changed into front air inflow, the negative pressure difference cannot be generated, the phenomenon that according to an air inlet device, during vehicle running, the negative pressure is formed nearby the surface,air inflow cannot be achieved or the air inflow volume is small is effectively avoided, the air inflow volume is guaranteed, and the ventilating and cooling effect of an air conditioner ventilation system is guaranteed. Meanwhile, since the air inlets are formed in the front end and the rear end, when the vehicle advances towards the two ends, normal air inflow can be guaranteed. The invention further discloses the railway vehicle comprising the above air inlet device.

Description

technical field [0001] The invention relates to the field of rail vehicles, in particular to an air intake device for rail vehicles. Furthermore, the invention also relates to a rail vehicle comprising the above-mentioned air intake device. Background technique [0002] At present, rail vehicles are equipped with air-conditioning systems to achieve ventilation in the vehicle interior and improve comfort and safety. The air-conditioning system needs to be equipped with an air intake device for the entry of outside air. At present, the air intake device of a rail vehicle is usually installed on the surface of the vehicle, such as the roof, the side wall of the car body, and the side suspension beam. [0003] The air inlet of the existing air intake device is usually located on the upper surface of the device. When the vehicle is running, the air flow rate on the upper surface is faster, thereby generating negative pressure, and as the vehicle running speed increases, the nega...

Problems solved by technology

[0003] The air inlet of the existing air intake device is usually located on the upper surface of the device. When the vehicle is running, the air flow rate on the upper surface is faster, thereby generating a negative pressure, and as the speed of the vehicle increases, the negative pressure difference will continue Increase, the existence of negative pressure difference causes the air volume entering the air inlet device from the air inlet on the upper surface to decrease

The instability of the air intake will directly affect the cooling effect of the air conditioning and ventilation system, thus affecting the working status of the components in the vehicle that need ventilation and cooling, and affecting the operation safety of the vehicle
