Description
Die Erfindung bezieht sich auf die Anordnung eines Kondensators in einem Fahrzeug und die zweckmäßige Ausgestaltung eines mittels Dampfkraftmaschine betriebenen Fahrzeuges, insbesondere Schienentriebwagens höherer Geschwindigkeit mit stromlinienförmiger Verkleidung und Kondensationseinrichtung. Bei bekannten Einrichtungen ähnlicher Art erfährt die Kühlluft des Kondensators erhebliche Richtungswechsel, wodurch bedeutende Energieverluste entstehen.The invention relates to the arrangement of a capacitor in a vehicle and the appropriate design of a vehicle powered by a steam engine, especially rail cars with higher speed and more streamlined Cladding and condensation device. In known devices of a similar type, the cooling air of the condenser experiences considerable Change of direction, resulting in significant energy losses.
Gemäß der Erfindung wird der Kondensator in den Weg eines Kühlluftstromes gestellt, der von der Stirnwand des Fahrzeuges aus, sich allmählich erweiternd, zu einer sich quer über das Fahrzeug erstreckenden Durchtrittsöffnung im oberen Teil der zweckmäßig stromlinienförmigen Fahrzeugverkleidung odeq in umgekehrter Richtung geführt ist. Besonders vorteilhaft ist es, wenn die untere Begrenzungsfläche des Kondensatorkühlluftstromes durch die Fortsetzung der oberen Verkleidung des Fahrzeuges gebildet wird.According to the invention, the condenser is placed in the path of a cooling air flow, from the front wall of the vehicle, gradually expanding into one across the vehicle extending passage opening in the upper part of the expedient streamlined vehicle cladding odeq is performed in the opposite direction. It is particularly advantageous if the lower Boundary surface of the condenser cooling air flow through the continuation of the upper Cladding of the vehicle is formed.

Abb. 2 denselben Teil des Triebwagens im Grundriß.Fig. 2 the same part of the railcar in plan.
Der in der Zeichnung nicht ^dargestellte Teil des stromlinienförmig verkleideten Fahrzeuges kann von beliebiger, an, sich bekannter Gestaltung sein. In der stromlinienförmigen Verkleidung 1 des Fahrzeuges bilden die obere Begrenzungsfläche 2, die untere Begrenzungsfläche 3 und die beiden seitlichen Begrenzungswände 4 und 5 einen Kühlluftkanal 6 im Fahrzeug, in dem der zu kühlende Kondensator 7 angeordnet ist. Der im Kondensator 7 kondensierte Dampf wird in einem nicht dargestellten Kessel erneut verdampft und wiederum zur Speisung der Antriebsmaschine und der Hüfsdampfmaschine verwendet. That part of the streamlined vehicle not shown in the drawing can be of any design that is known per se. In the streamlined Cladding 1 of the vehicle forms the upper boundary surface 2, the lower boundary surface 3 and the two lateral boundary walls 4 and 5 a cooling air duct 6 in the vehicle in which the condenser 7 to be cooled is arranged. The one in the condenser 7 condensed steam is evaporated again in a boiler, not shown and in turn used to feed the prime mover and the auxiliary steam engine.
Bewegt sich das Fahrzeug in Richtung des Pfeiles A, so wird die Kühlluft durch eine Öffnung 8 in der Stirnwand der Wagenverkleidung in den Kanal 6 eingesaugt und durch den Kondensator 7 hindurchgeleitet. Die Öffnung 8 kann mit einem an sich bekannten Gitter versehen sein. Die Kühlluft tritt nach ihrem Durchgang durch den. Kondensator 7 zwischen der Verkleidungskante 9 und demIf the vehicle moves in the direction of arrow A, the cooling air is sucked into the duct 6 through an opening 8 in the end wall of the vehicle lining and passed through the condenser 7. The opening 8 can be provided with a grille known per se. The cooling air occurs after it has passed through the. Capacitor 7 between the cladding edge 9 and the

gegenüberliegenden Teil der Fläche 3 wieder ins Freie. Wie Abb. 1 deutlich zeigt, wird die untere Begrenzungsfläche 3 des Kühlluftkanals 6 durch die Fortsetzung des Ober^ teiles 10 der Wagenverkleidung gebildet. Dieser Teil 10 der Verkleidung liegt um dje Höhef/ tiefer als die Kante 9 der WagenveV-j< kleidung 11, welche sich oberhalb des Kühlluftkanals 6 befindet. Die strichpunktierte Linie 12 bezweckt lediglich, diesen Höhenunterschied der Verkleidungsteile deutlich zu machen. Bei Fahrt in Richtung des Pfeiles B wird infolge des beschriebenen Höhenunterschiedes die Grenzluftschicht mit großer Gewait in den Kanal 6 eingesaugt, so daß die Kühlung des Kondensators auch bei dieser Fahrtrichtung eine außerordentlich wirksame ist.opposite part of the surface 3 back into the open. As Fig. 1 clearly shows, the lower boundary surface 3 of the cooling air duct 6 is formed by the continuation of the upper part 10 of the car lining. This part 10 of the cladding lies by the height f / lower than the edge 9 of the WagenveV-j <clothing 11, which is located above the cooling air duct 6. The purpose of the dash-dotted line 12 is only to make this difference in height between the trim parts clear. When driving in the direction of arrow B , the boundary air layer is sucked into the channel 6 with great accuracy due to the height difference described, so that the cooling of the condenser is extremely effective even in this direction of travel.
In Weiterbildung des Erfindungsgedankens ist die obere Luftdurchtrittsstelle für die Kühlluft, insbesondere die Kante 9, so weit von der Stirnwand des Fahrzeuges, in der sich die Öffnung 8 befindet, entfernt angeordnet, daß die Grenzluftschicht der Außenhaut des Fahrzeuges bei Fahrt in Richtung des Pfeiles B in den Kanal eingesaugt wird, bevor sie sich durch Wirbelbildung von der Fahrzeugverkleidung abgelöst hat.In a further development of the concept of the invention, the upper air passage point for the cooling air, in particular the edge 9, is arranged so far away from the front wall of the vehicle in which the opening 8 is located that the boundary air layer of the outer skin of the vehicle when driving in the direction of arrow B is sucked into the duct before it has become detached from the vehicle paneling due to the formation of eddies.
Um die Saugwirkung zu vergrößern, ist noch ein um die Welle 13 drehbarer Lüfter 14 vorgesehen.In order to increase the suction effect, there is also a fan 14 which can be rotated about the shaft 13 intended.
Um eine genügend große Kühlfläche zu erhalten, ist es zweckmäßig, den Kondensator geneigt zur Kanalachse in den Kühlluftweg zu stellen.In order to obtain a sufficiently large cooling surface, it is advisable to use the condenser inclined to the duct axis in the cooling air path.
