Definitions

  • the invention relates to a rail vehicle with at least one ventilated roof container and at least one above the roof container spaced therefrom arranged first shading sheet, wherein exhaust air is discharged from the ventilated roof container by means of a ventilation duct.
  • the invention has for its object to counteract heating of a roof of a rail vehicle by solar radiation.
  • An inventive rail vehicle of passenger transport in particular of local passenger transport, comprises at least one ventilated roof container and at least one above the roof container, in the vertical direction of the roof container
  • the first shading plate serves to reduce the solar radiation on the roof container and is therefore also referred to as awning.
  • the roof container has a fan, for example, a rotating paddle wheel, which actively carries air from the roof container, the so-called exhaust air.
  • the rail vehicle according to the invention comprises a ventilation duct, which leads the exhaust air. In addition to an outlet for the exhaust air, it has at least one inlet in the region of the gap between the roof container and the first shading plate.
  • the ventilation duct is now designed as a so-called jet pump, sometimes also referred to as venturi pump, and arranged on the rail vehicle, in particular past the gap between the roof container and the first shading sheet, so that the exhaust air is at the inlet of the ventilation duct in the region of the gap between Passing roof container and first shading sheet is passed through the exhaust air flowing through the ventilation duct, a negative pressure in the region of the inlet of the ventilation duct in the region of the gap between the roof container and the first shading plate is generated so that air from the environment of the rail vehicle in the gap between roof containers and first Abschattungsblech nachströmt.

Abstract

L'invention concerne un véhicule ferroviaire muni d'au moins un caisson de toit (1) ventilé et d'au moins une première tôle de projection d'ombre (2) agencée au-dessus du caisson de toit (1) et écartée de ce dernier. Au moyen d'un canal de ventilation (7) configuré sous la forme d'une pompe à injection et présentant au moins une entrée (8) dans la zone d'une fente (5) entre le caisson de toit (1) et la première tôle de projection d'ombre (2), l'air évacué du caisson de toit (1) ventilé passe au niveau de l'entrée (8) de telle manière qu'une dépression est produite dans la zone de l'entrée (8) du canal de ventilation (7) par l'air évacué traversant le canal de ventilation (7), de sorte que l'air provenant de l'extérieur du véhicule ferroviaire s'écoule dans la fente (5) entre le caisson de toit (1) et la première tôle de projection d'ombre (2).
