Problems solved by technology

However, due to the positive pressure area generated on the windward side of the air-conditioning unit cowl and the pantograph cowl, and there is a gap between the air-conditioning unit cowl and the pantograph cowl, the air-conditioning unit cowl and the pantograph The air flow in the gap between the pantograph shrouds is turbulent, and the pressure difference resistance increases, resulting in greater pressure difference resistance and aerodynamic noise

Abstract

The invention provides an airflow guiding hood for a railway vehicle and the railway vehicle, and relates to the technology of vehicle roof airflow guiding hoods for railway vehicles. The airflow guiding hood for the railway vehicle comprises a first airflow guiding hood and a second airflow guiding hood, wherein the first airflow guiding hood is mounted in an air conditioning unit area; the second airflow guiding hood is mounted in a pantograph area; the first airflow guiding hood is connected with the second airflow guiding hood through a connecting piece; the connecting piece comprises a first connecting end and a second connecting end, wherein the first connecting end is connected with the first airflow guiding hood, and the second connecting end is connected with the second airflow guiding hood, so that the first airflow guiding hood is in smooth transition connection with the second airflow guiding hood through the connecting piece. The railway vehicle comprises the airflow guiding hood for the railway vehicle. The first airflow guiding hood is in smooth transition connection with the second airflow guiding hood through the connecting piece, so that the smooth transition of the air conditioning unit area and the pantograph area is realized; the air between the air conditioning unit area and the pantograph area has a function of guiding, so that the air resistance at the top of the vehicle body of the railway vehicle is reduced, and aerodynamic noises at the top of the vehicle body of the railway vehicle is reduced.

Description

technical field [0001] The invention relates to the technology of a rail vehicle roof deflector, in particular to a rail vehicle deflector and a rail vehicle. Background technique [0002] The top of the car body of a rail vehicle is usually equipped with an air conditioning unit and a pantograph. When the rail vehicle is running at high speed, the air conditioning unit and pantograph on the top of the car body will be in contact with the air, thereby generating resistance, which is not conducive to the high-speed operation of the rail vehicle. [0003] In the prior art, air-conditioning unit shrouds are usually installed on the air-conditioning units, and pantograph shrouds are installed on the pantographs. However, due to the positive pressure area generated on the windward side of the air-conditioning unit cowl and the pantograph cowl, and there is a gap between the air-conditioning unit cowl and the pantograph cowl, the air-conditioning unit cowl and the pantograph The ...
