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.
• the ventilation duct has in particular the shape of a venturi nozzle or a correspondingly modified one
• the ventilation duct is designed as a Venturi nozzle.
• a Venturi nozzle has two cones facing each other and a take-off tube at the constriction between the cones of the Venturi nozzle, which take-off tube has the inlet.
• the first shading plate has first openings for the passage of air.
• the rail vehicle may moreover have a further, second shading plate, which is spaced from the first shading plate and spaced from the roof container, arranged between the first shading plate and roof container so that the at least one inlet of the ventilation duct is arranged in the region of a gap between the roof container and the second shading plate. Both Abschattungsbleche are arranged in particular parallel to each other.
• the second shading plate may also have second openings for the passage of air.
• the first shading plate is then arranged offset to the first shading plate, so that the first openings of the first shading plate are at least partially shadowed by the second shading plate in the vertical direction, ie in particular perpendicularly on both horizontally arranged shading plates, so that the openings through the first shading plate Openings of the first shading plate passing solar radiation is reduced by the second shading plate.
• the intensity of the incident on the roof container solar radiation is limited.
• the sheet metal tongues have for example an angle in the interval 10 ° ... 80 °, in particular 30 ° ... 50 ° to the first shading plate in a plane parallel to a longitudinal axis of the rail vehicle and perpendicular to the first shading plate.
• the height of the gap above the roof container and thus the distance between the first or the second shading plate and the roof container is at least 10 mm, in particular at least 20 mm.
• the invention allows numerous embodiments. It will be explained in more detail with reference to the following figure, in which a design example is shown.
• the figure shows a cross section through a roof of a rail vehicle according to the invention.
• a roof container 1 On the roof, a roof container 1 is arranged, which encloses devices waterproof.
• two parallel Abschattungsbleche 2 and 3 are arranged. Between the first shading plate 2 and the second shading plate
• a second gap 5 is located between the second shading plate 3 and the roof container 1.
• the second gap 5 is larger here than the first gap
• the first shading plate 2 has first openings.
• the second shading plate 3 is free of second openings.
• Sheet metal tongues 6 project from the first shading sheet 2 to the second shading sheet 3.
• the sheet metal tongues 6 additionally shade the second shading sheet 3 against solar radiation through the first openings.
• the roof container 1 is ventilated, for example by means of an air column for cooling of heat sinks and chokes. It thus has a fan which conveys exhaust air from the roof container 1 out.
• the exhaust air is passed through a ventilation duct 7.
• the ventilation duct 7 serves as a jet pump and is designed accordingly as a Venturi nozzle here. It has an entrance 9 to the roof container 1 in order to receive the exhaust air and to deliver an outlet 10 to the exhaust air into the environment.
• it has an inlet 8, which is arranged in the region of the second gap 5 and serves to suck in air between the second shading plate 3 and the roof container 1.
• Roof container 1 generates a negative pressure in the region of the inlet 8 of the ventilation duct 1 in the region of the second gap 5 between the roof container 1 and the second shading plate 3, whereby air is forced out of the second gap 5 into the inlet 8 of the ventilation duct 1, so that air is exhausted the environment of the rail vehicle flows in the second gap 5 between the roof container 1 and the second shading plate 3 to the inlet 8 of the ventilation duct 1.
• the roof or the roof container is thus forced ventilated from the outside without an additional fan is provided for, since simply the existing fan of the roof container or its exhaust air is used.
