Description

Beschreibung description
Fremdbelüftung eines Dachcontainers eines Schienenfahrzeugs Die Erfindung betrifft ein Schienenfahrzeug mit zumindest einem belüfteten Dachcontainer und zumindest einem oberhalb des Dachcontainers von diesem beabstandet angeordneten ersten Ab- schattungsblech, wobei Abluft aus dem belüfteten Dachcontainer mittels eines Lüftungskanals abgeführt wird. 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.
In sonnigen und dadurch heißen Regionen werden auf dem Dach eines Schienenfahrzeugs in Containern angeordnete Aggregate stark aufgeheizt. Dies kann zu Beschädigungen von temperatursensiblen Bauteilen, wie z.B. Steuerungen führen. Um dem ab- zuhelfen, werden Sonnensegel über besonders kritischen Stellen des Containers angeordnet, beispielsweise mit einem Abstand von ca. 20mm. Es wird jedoch kaum Luft zwischen Container und Sonnensegel ausgetauscht und dieser daher kaum gekühlt. Ein wesentlich größerer Abstand könnte zwar zu einem ausreichenden Luftaustausch führen, dieser ginge jedoch einher mit einer vergleichsweise massiveren AbStützung des Sonnensegels und einem gegebenenfalls unerwünscht hohen Dachaufbau . Der Erfindung liegt die Aufgabe zugrunde, einer Aufheizung eines Dachs eines Schienenfahrzeugs durch Sonneneinstrahlung entgegenzuwirken . In sunny and thus hot regions, aggregates arranged in containers on the roof of a rail vehicle are strongly heated up. This can damage the temperature sensitive components, e.g. Lead controls. In order to remedy this, awnings are placed over particularly critical areas of the container, for example at a distance of about 20 mm. However, hardly any air is exchanged between the container and the awning and therefore it is hardly cooled. Although a much greater distance could lead to a sufficient exchange of air, this would go hand in hand with a comparatively more massive support of the awning and possibly an undesirably high roof structure. The invention has for its object to counteract heating of a roof of a rail vehicle by solar radiation.
Gelöst wird die Aufgabe durch den Gegenstand des unabhängigen Patentanspruchs 1. Weiterbildungen und Ausgestaltungen derThe object is achieved by the subject matter of independent claim 1. Further developments and refinements of
Erfindung finden sich in den Merkmalen der abhängigen Patentansprüche wieder. Invention can be found in the features of the dependent claims again.
Ein erfindungsgemäßes Schienenfahrzeug des Personenverkehrs, insbesondere des Personennahverkehrs, umfasst zumindest einen belüfteten Dachcontainer und zumindest ein oberhalb des Dachcontainers, in vertikaler Richtung vom Dachcontainer 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
beabstandet angeordnetes erstes Abschattungsblech . Zwischen dem Dachcontainer und dem ersten Abschattungsblech existiert daher ein Spalt größer Null. Das erste Abschattungsblech dient der Verringerung der Sonneneinstrahlung auf den Dachcontainer und wird daher auch als Sonnensegel bezeichnet. Es ist insbesondere ein dünnes, jedoch für die erwarteten Druckverhältnisse ausreichend stabiles Blech aus Stahl. Der Dachcontainer verfügt über einen Lüfter, beispielsweise ein rotierendes Schaufelrad, welches aktiv Luft aus dem Dachcontainer befördert, die sogenannte Abluft. Des Weiteren umfasst das erfindungsgemäße Schienenfahrzeug einen Lüftungskanal, welcher die Abluft führt. Er weist neben einem Auslass für die Abluft zumindest einen Einlass im Bereich des Spalts zwischen dem Dachcontainer und dem ersten Abschattungsblech auf . Der Lüftungskanal ist nun als sogenannte Strahlpumpe, gele- gentlich auch als Venturi-Pumpe bezeichnet, ausgestaltet und so am Schienenfahrzeug angeordnet, insbesondere so am Spalt zwischen Dachcontainer und erstem Abschattungsblech vorbeigeführt, dass die Abluft so an dem Einlass des Lüftungskanals im Bereich des Spalts zwischen Dachcontainer und erstem Ab- schattungsblech vorbeigeführt wird, dass durch die durch den Lüftungskanal strömende Abluft ein Unterdruck im Bereich des Einlasses des Lüftungskanals im Bereich des Spalts zwischen Dachcontainer und erstem Abschattungsblech erzeugt wird, so dass Luft aus der Umgebung des Schienenfahrzeugs in den Spalt zwischen Dachcontainer und erstem Abschattungsblech nachströmt. Der Lüftungskanal weist dazu insbesondere die Form einer Venturidüse oder einer entsprechend modifizierten spaced arranged first shading plate. Between The roof container and the first shading plate therefore has a gap greater than zero. The first shading plate serves to reduce the solar radiation on the roof container and is therefore also referred to as awning. In particular, it is a thin steel sheet which is sufficiently stable for the expected pressure conditions. 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. Furthermore, 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
Lavaldüse auf. Die Luft aus dem Spalt wird in den Einlass des Lüftungskanals gedrückt, umgangssprachlich gesogen. Dadurch entsteht eine Strömung der Luft im Spalt zum Einlass hin, wodurch Luft aus der Umgebung des Spalts in den Spalt gedrückt, bzw. umgangssprachlich gesogen, wird. Eine einfache Kühlung des Dachcontainers ist gewährleistet, da dieser von Umgebungsluft umspült wird. Laval nozzle on. The air from the gap is forced into the inlet of the ventilation duct, colloquially sucked. This creates a flow of air in the gap towards the inlet, whereby air from the vicinity of the gap is pressed into the gap, or colloquially sucked. A simple cooling of the roof container is guaranteed because it is surrounded by ambient air.
Eine Weiterbildung der Erfindung sieht vor, dass der Lüftungskanal als Venturi-Düse ausgestaltet ist. Eine Venturi- Düse weist beispielsweise zwei gegeneinander gerichtete Konen und ein Abnahmerohr an der Engstelle zwischen den Konen der Venturi -Düse , welches Abnahmerohr den Einlass aufweist. A development of the invention provides that the ventilation duct is designed as a Venturi nozzle. For example, 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.
Weitergebildet weist das erste Abschattungsblech erste Öff- nungen zum Durchtritt von Luft auf. Das Schienenfahrzeug kann darüber hinaus ein weiteres, zweites Abschattungsblech aufweisen, welches beabstandet vom ersten Abschattungsblech und beabstandet vom Dachcontainer, zwischen erstem Abschattungsblech und Dachcontainer so angeordnet ist, dass der zumindest eine Einlass des Lüftungskanals im Bereich eines Spalts zwischen Dachcontainer und zweitem Abschattungsblech angeordnet ist. Beide Abschattungsbleche sind insbesondere parallel zueinander angeordnet. Auch das zweite Abschattungsblech kann zweite Öffnungen zum Durchtritt von Luft aufweisen. Es ist dann gemäß einer weiteren Weiterbildung versetzt zum ersten Abschattungsblech angeordnet, so dass die ersten Öffnungen des ersten Abschattungsblech vom zweiten Abschattungsblech in vertikaler Richtung, also insbesondere senkrecht auf beiden horizontal angeordneten Abschattungsblechen, zumindest teil- weise abgeschattet sind, so dass die durch die ersten Öffnungen des ersten Abschattungsblech tretende Sonneneinstrahlung, durch das zweite Abschattungsblech verringert wird. Dadurch wird die Intensität der auf den Dachcontainer auftreffenden Sonneneinstrahlung begrenzt. Further developed, 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. According to a further development, it 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. As a result, the intensity of the incident on the roof container solar radiation is limited.
Des Weiteren kann zumindest das erste Abschattungsblech Furthermore, at least the first shading plate
Blechzungen aufweisen, welche die ersten Öffnungen im ersten Abschattungsblech zumindest in vertikaler Richtung zumindest teilweise bedecken. Die Blechzungen weisen beispielsweise ei- nen Winkel im Intervall 10°...80°, insbesondere 30°...50° zum ersten Abschattungsblech in einer Ebene parallel zu einer Längsachse des Schienenfahrzeugs und senkrecht zum ersten Abschattungsblech auf. Licht fällt durch die Blechzungen in einem kleinen Einfallswinkel durch die ersten Öffnungen im ers- ten Abschattungsblech auf das Dach, und die Intensität der Einstrahlung wird weiter verringert. Die Höhe des Spalts über dem Dachcontainer und damit der Abstand zwischen dem ersten oder dem zweiten Abschattungsblech und dem Dachcontainer beträgt zumindest 10 mm, insbesondere wenigstens 20 mm. Have sheet tongues, which cover the first openings in the first Abschattungsblech at least partially in the vertical direction. 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. Light falls through the sheet metal tongues at a small angle of incidence through the first openings in the first shading sheet to the roof, and the intensity of the radiation is further reduced. 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.
Die Erfindung lässt zahlreiche Ausführungsformen zu. Sie wird anhand der nachfolgenden Figur näher erläutert, in der ein Ausgestaltungsbeispiel dargestellt ist. Die Figur zeigt einen Querschnitt durch ein Dach eines erfindungsgemäßen Schienenfahrzeugs. Auf dem Dach ist ein Dachcontainer 1 angeordnet, welcher Geräte wasserdicht umschließt. Vertikal oberhalb des Dachcontainers 1 sind zwei parallel angeordnete Abschattungsbleche 2 und 3 angeordnet. Zwischen dem ersten Abschattungsblech 2 und dem zweiten AbschattungsblechThe 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. On the roof, a roof container 1 is arranged, which encloses devices waterproof. Vertically above the roof container 1, two parallel Abschattungsbleche 2 and 3 are arranged. Between the first shading plate 2 and the second shading plate
3 ist ein erster Spalt 4. Ein zweiter Spalt 5 befindet sich zwischen dem zweiten Abschattungsblech 3 und dem Dachcontainer 1. Der zweite Spalt 5 ist hier größer als der erste Spalt3 is a first gap 4. 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
4 und beträgt hier ungefähr 20 mm. Das erste Abschattungs- blech 2 weist erste Öffnungen auf. Das zweite Abschattungsblech 3 ist hingegen frei von zweiten Öffnungen. Blechzungen 6 ragen vom ersten Abschattungsblech 2 zum zweiten Abschattungsblech 3. Die Blechzungen 6 schatten das zweite Abschattungsblech 3 zusätzlich gegen Sonneneinstrahlung durch die ersten Öffnungen ab. 4 and here is about 20 mm. The first shading plate 2 has first openings. The second shading plate 3, however, 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.
Der Dachcontainer 1 ist belüftet, z.B. mittels einer Luftsäule zur Kühlung von Kühlkörpern und Drosseln. Er weist somit einen Lüfter auf, welcher Abluft aus dem Dachcontainer 1 her- aus fördert. Die Abluft wird durch eine Lüftungskanal 7 geführt. Der Lüftungskanal 7 dient als Strahlpumpe und ist hier entsprechend als Venturi-Düse ausgeführt. Er weist einen Eingang 9 zum Dachcontainer 1 auf, um die Abluft aufzunehmen und einen Auslass 10 um die Abluft in die Umgebung abzugeben. Zu- sätzlich weist er einen Einlass 8 auf, welcher im Bereich des zweiten Spalts 5 angeordnet ist und dazu dient Luft zwischen dem zweiten Abschattungsblech 3 und dem Dachcontainer 1 anzusaugen. Die durch den Lüftungskanal 7 strömende Abluft des Dachcontainers 1 erzeugt ein Unterdruck im Bereich des Einlasses 8 des Lüftungskanals 1 im Bereich des zweiten Spalts 5 zwischen Dachcontainer 1 und zweitem Abschattungsblech 3, wodurch Luft aus dem zweiten Spalt 5 in den Einlass 8 des Lüf- tungskanals 1 gedrückt wird, so dass Luft aus der Umgebung des Schienenfahrzeugs in den zweiten Spalt 5 zwischen Dachcontainer 1 und zweitem Abschattungsblech 3 zum Einlass 8 des Lüftungskanals 1 nachströmt. Das Dach bzw. der Dachcontainer ist somit auch von außen zwangsbelüftet, ohne dass ein zusätzlicher Lüfter dafür vorgesehen ist, da einfach der vorhandene Lüfter des Dachcontainers bzw. dessen Abluft genutzt wird. 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. In addition, 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. The exhaust air flowing through the ventilation duct 7 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.
