Description

Beschreibung description
Schienenfahrzeug mit Traktionskühlanlage Rail vehicle with traction cooling system
Die Erfindung bezieht sich auf ein Schienenfahrzeug nach dem Oberbegriff von Anspruch 1. The invention relates to a rail vehicle according to the preamble of claim 1.
Danach ist ein Schienenfahrzeug mit wenigstens einer After that is a rail vehicle with at least one
Traktionskomponente, die mittels einer Traktionskühlanlage kühlbar ist, und mit einer Klimaanlage bekannt, die zur Kli¬ matisierung eines Fahrgastinnenraums des Schienenfahrzeugs vorgesehen ist und einen mit dem Fahrgastinnenraum strömungstechnisch verbundenen und aus dem Schienenfahrzeug herausführenden Fortluftkanal aufweist, wobei die Traktionskühlanlage einen Wärmetauscher umfasst, an dem mittels eines Traktionskomponente, which is cooled by means of a traction cooling system, and known with an air conditioner, which is provided for Kli ¬ matization of a passenger compartment of the rail vehicle and having a fluidic connected to the passenger compartment and leading out of the rail vehicle exhaust air duct, the traction cooling system comprises a heat exchanger to which by means of a
Lüftermoduls angesaugte Umgebungsluft von einer Lufteinlass¬ seite des Wärmetauschers aus zu einer Luftauslassseite des Wärmetauschers zur Entwärmung des Wärmetauschers vorbeige¬ führt ist. Fan module sucked ambient air from an air inlet ¬ side of the heat exchanger to an air outlet side of the heat exchanger for cooling the heat exchanger vorbeige ¬ leads.
Wie vorstehend beschrieben, liegen somit bei einem herkömmlichen Schienenfahrzeug für die Entwärmung der wenigstens einen Traktionskomponente einerseits und die Abführung von Raumluft aus dem Fahrgastinnenraum des Schienenfahrzeugs verschiedene Geräte vor. So dient die typischer Weise unterflur angeordne¬ te Traktionskühlanlage, mittels deren Wärmetauscher Kühlfluid für die Traktionskomponente abgekühlt wird, zur Aufrechter¬ haltung des Betriebs der Traktionskomponente. Bei dieser kann es sich beispielsweise um einen Stromrichter, aber auch einen Transformator handeln. As described above, in a conventional rail vehicle for the heat dissipation of the at least one traction component on the one hand and the discharge of room air from the passenger compartment of the rail vehicle are thus different devices. Thus, typically under the floor is arrange ¬ te traction cooling system by means of which heat exchanger cooling fluid for the traction component is cooled is used, the upright attitude ¬ the operation of the traction component. This can be, for example, a power converter, but also a transformer.
Demgegenüber saugt das Fortluftgerät Luft aus dem Fahrgastin¬ nenraum an und führt sie nach außerhalb des Fahrzeugs. In contrast, the exhaust air device sucks air from the Fahrgastin ¬ nenraum and guides it to the outside of the vehicle.
Vor diesem Hintergrund besteht die allgemeine Aufgabe, die Komplexität der strömungstechnischen Ausrüstung bei einem Schienenfahrzeug zu vermindern. Diese Aufgabe wird bei dem eingangs genannten Schienenfahr¬ zeug durch die kennzeichnenden Merkmale des Anspruchs 1 ge¬ löst. Danach ist bei dem Schienenfahrzeug vorgesehen, dass ein Aus¬ lassende des Fortluftkanals der Klimaanlage an der Luftein¬ lassseite des Wärmetauschers der Traktionskühlanlage derart angeordnet ist, dass das Lüftermodul in dem Fortluftkanal be¬ findliche Fortluft ansaugt, so dass die Traktionskühlanlage einen Fortluftmassenstrom bewirkt und als Fortluftgerät ar¬ beitet . Against this background, the general task is to reduce the complexity of the fluidic equipment in a rail vehicle. This object is achieved by the characterizing features of claim 1 ge ¬ triggers in the aforementioned rail vehicle ¬ . Thereafter, it is provided in the rail vehicle that an off ¬ lassende the exhaust air duct of the air conditioner on the Luftein ¬ lassseite the heat exchanger of the traction cooling system is arranged such that the fan module sucks in the exhaust duct be ¬ sensitive exhaust air, so that the traction cooling system causes a mass flow of exhaust air and as Exhaust air device ¬ beitet ar.
Gemäß dieser Vorgehensweise entfällt das im Stand der Technik eingesetzte Fortluftgerät als gesonderte Komponente des According to this procedure, the exhaust air device used in the prior art is omitted as a separate component of the
Schienenfahrzeugs. Vielmehr übernimmt die Traktionskühlanlage die Funktion des Fortluftgerätes zur Abführung von Fortluft aus dem Fahrgastinnenraum des Schienenfahrzeugs. Dazu kann es erforderlich sein, dass die Traktionskühlanlage hinsichtlich der Leistung ihres Lüfters/ihrer Lüfteranordnung gegenüber herkömmlichen Traktionskühlanlagen größer bemessen ist. Rail vehicle. Rather, the traction cooling system takes over the function of the exhaust air device for the discharge of exhaust air from the passenger compartment of the rail vehicle. This may require that the traction cooling system be sized larger than conventional traction cooling systems in terms of the performance of their fan / their fan assembly.
Es ergibt sich der Vorteil, dass Bauraum im Unterflurbereich des Schienenfahrzeugs eingespart wird. Auch ist zu erwarten, dass eine Gesamtmasse, ein elektrischer Energieverbrauch und Gesamtkosten des Schienenfahrzeugs vermindert werden. This results in the advantage that space is saved in the underfloor area of the rail vehicle. It is also expected that a total mass, an electrical energy consumption and a total cost of the rail vehicle will be reduced.
Bevorzugt kann bei vorgegebener Mindestdrehzahl des Preferably, at a predetermined minimum speed of the
Lüftermoduls der Fortluftkanal derart geometrisch ausgelegt und mit seinem Auslassende an der Lufteinlassseite des Wärme- tauschers der Traktionskühlanlage angeordnet sein, dass ein nach den Anforderungen der Klimatisierung des Fahrzeuginnenraums an die Klimaanlage erforderlicher Fortluftmassenstrom bei der Mindestdrehzahl abführbar ist. Dies gewährleistet auch für den Fall, dass die elektrische Traktionskomponente aktuell keinen Kühlbedarf hat und das Lüftermodul bei der vorgegebenen Mindestdrehzahl betrieben ist, dass ausreichend Fortluft aus dem Fahrzeuginnenraum abführbar ist. Vorteilhafterweise kann der Fortluftmassenstrom in der Fortluftleitung steuerbar sein. Dies gestattet es, auf etwaige, z.B. auch kurzfristig auftretende besonders hohe Anforderun¬ gen an Kühlleistung für die Traktionskomponente reagieren zu können. In diesem Fall kann der Fortluftmassenstrom derart abgesenkt werden, dass mehr Umgebungsluft von dem Lüftermodul angesaugt wird, so dass eine höhere Entwärmung der elektri¬ schen Traktionskomponente durch die Traktionskühlanlage er¬ folgen kann. Fan module of the exhaust duct so geometrically designed and arranged with its outlet end to the air inlet side of the heat exchanger of the traction cooling system that a required according to the requirements of the air conditioning of the vehicle interior to the air conditioning exhaust air mass flow at the minimum speed can be discharged. This ensures even in the event that the electric traction component currently has no cooling demand and the fan module is operated at the predetermined minimum speed that sufficient exhaust air from the vehicle interior can be discharged. Advantageously, the exhaust air mass flow in the exhaust air line can be controlled. This makes it possible to respond to any such short notice occurring particularly high Anforderun ¬ gen cooling capacity for traction component. In this case, the exhaust air mass flow can be lowered so that more ambient air is sucked in by the fan module so that a higher heat dissipation of electrical ¬ rule traction component by the traction cooling system can ¬ follow.
Der Fortluftmassenstrom kann beispielsweise mittels einer drehbaren Luftklappe steuerbar sein, die zum Verwirklichen verschiedener freier Querschnitte des Fortluftkanals in den Fortluftkanal integriert ist. Wird beispielsweise eine Tempe- ratur der zu kühlenden elektrischen Traktionskomponente überwacht und diese Überwachung führt zum Feststellen eines erhöhten Kühlbedarfs, kann die drehbare Luftklappe den freien Querschnitt innerhalb des Fortluftkanals derart verkleinern, dass trotz erhöhter Drehzahl des Lüftermoduls der Fortluft- massenstrom im Wesentlichen gleich bleibt. The exhaust air mass flow can be controlled, for example, by means of a rotatable air damper, which is integrated into the exhaust air duct for realizing various free cross sections of the exhaust air duct. If, for example, a temperature of the electric traction component to be cooled is monitored and this monitoring leads to the detection of an increased cooling requirement, the rotatable air damper can reduce the free cross section within the exhaust air duct in such a way that the exhaust air mass flow remains essentially the same despite the increased speed of the fan module.
Allgemein ausgedrückt, kann der Fortluftmassenstrom abhängig von einem betriebsbedingten Kühlbedarf der wenigstens einen Traktionskomponente an die Traktionskühlanlage gesteuert sein. Generally speaking, the exhaust air mass flow may be controlled depending on an operational cooling requirement of the at least one traction component to the traction cooling system.
Eine Überwachung des Fortluftmassenstroms im Fortluftkanal kann mittels eines Luftmengensensors erfolgen. Ein Ausführungsbeispiel der Erfindung wird nachfolgend unter Bezugnahme auf die Zeichnung noch näher erläutert. Die einzi¬ ge Figur zeigt schematische Blockdiagrammdarstellungen einer Traktionskühlanlage mit damit zusammenwirkenden Komponenten eines Schienenfahrzeugs. A monitoring of the exhaust air mass flow in the exhaust duct can be done by means of an air flow sensor. An embodiment of the invention will be explained in more detail with reference to the drawings. The only peo ¬ ge figure shows a schematic block diagram representations of a traction cooling system with cooperating components of a rail vehicle.
Wie in der Figur dargestellt ist, umfasst eine beispielsweise bei einem Schienenfahrzeug eingesetzte Traktionskühlanlage 1 einen Wärmtauscher 2 sowie ein Lüftermodul 3. Das Lüftermodul 3 wiest im vorliegenden Ausführungsbeispiel ein Lüfterrad 4 auf, das Umgebungsluft 5 in Richtung auf eine Lufteinlasssei te 6 des Wärmetauschers 2 ansaugt und an dem Wärmetauscher 2 vorbeiführt, wonach die erwärmte Umgebungsluft auf einer Luftauslassseite 7 den Wärmetauscher 2 verlässt. As shown in the figure, a Traktionskühlanlage used for example in a rail vehicle 1 includes a heat exchanger 2 and a fan module 3. The fan module 3 wiest in the present embodiment, a fan 4, the ambient air 5 in the direction of a Lufteinlasssei te 6 of the heat exchanger 2 sucks and past the heat exchanger 2, after which the heated ambient air leaves the heat exchanger 2 on an air outlet 7.
Bei dem Wärmetauscher 2 kann es sich um einen Luft/Fluid- Wärmetauscher handeln, wobei es sich bei dem Fluid um das Kühlfluid für eine zu entwärmende elektrische The heat exchanger 2 may be an air / fluid heat exchanger, wherein the fluid is the cooling fluid for an electrical
Traktionskomponente (z.B. Stromrichter, Transformator) handelt und das Kühlfluid einen Traktionskühlkreis durchströmt Traction component (e.g., power converter, transformer) and the cooling fluid flows through a traction cooling circuit
Durch geeignete Strömungsführung verlässt die den Wärmetau scher 2 passierende Umgebungsluft die Traktionskühlanlage in einem ausgeblasenen Luftstrom 8. By suitable flow guidance the Wärmetau exchanger 2 passing ambient air leaves the traction cooling system in a blown air stream. 8
Die Traktionskühlanlage 1 wirkt zudem als Fortluftgerät. Dazu transportiert ein Fortluftkanal 9 aus einem Fahrgastinnenraum des Schienenfahrzeugs zu der Lufteinlassseite 6 des Wärmetau- schers 2. Ein Auslassende 10 des Fortluftkanals 9 ist unmit¬ telbar an der Lufteinlassseite 6 des Wärmetauschers 2 ange¬ ordnet, so dass das Lüftermodul 3 an dem Auslassende 10 des Fortluftkanals 9 einen Unterdruck erzeugt, welcher dazu führt, dass angesaugte Luft 11 aus dem Fahrgastinnenraum ebenfalls den Wärmetauscher 2 passiert und dem Luftstrom 8 an ausgeblasener Luft hinzugefügt wird. Zu diesem Zweck kann es erforderlich sein, eine herkömmliche Traktionskühlanlage hin¬ sichtlich der Leistung ihres Lüftermoduls 3 derart aufzurüs¬ ten, dass parallel der Wärmetauscher 2 für die elektrische Antriebskomponente entwärmt und auch die Fortluft aus dem Fahrzeuginnenraum abgeführt werden kann. The traction cooling system 1 also acts as exhaust air device. To this end carries a exhaust air duct 9 of a passenger compartment of the rail vehicle to the air inlet side 6 of the heat exchanger 2. An outlet 10 of the exhaust air duct 9 is UNMIT ¬ telbar at the air inlet side 6 of the heat exchanger 2 is ¬ arranged so that the fan module 3 at the outlet 10 the exhaust air duct 9 generates a negative pressure which causes sucked air 11 from the passenger compartment also passes through the heat exchanger 2 and the air stream 8 is added to blown air. For this purpose it may be necessary for a conventional traction cooling system towards ¬ clearly the performance of their fan module 3 in such aufzurüs ¬ th that parallel the heat exchanger 2 entwärmt for the electric drive component and the exhaust air from the vehicle interior can be removed.
Für den Betrieb der Traktionskühlanlage hat grundsätzlich die Funktion der Kühlung der elektrischen Antriebskomponente Priorität. Bei beispielsweise plötzlich auftretendem erhöhten Kühlbedarf für die elektrische Antriebskomponente kann ein Fortluftmassenstrom trotz erhöhter Leistung des Lüftermoduls 3 ungeändert gehalten werden. Zu diesem Zweck ist in dem Fortluftkanal 9 ein Luftmengensensor 12 vorgesehen, mit dessen Hilfe eine Größe des Fortluftmassenstroms im Fortluftka¬ nal 9 überwachbar und messbar ist. Mit Hilfe einer in den Fortluftkanal 9 eingesetzten Luftklappe 13 kann die Größe des Fortluftmassenstroms geeignet gesteuert werden, in dem ein verbleibender freier Querschnitt des Fortluftkanals 9 ein¬ stellbar ist. Dazu ist die Luftklappe 13 drehbar aufgehängt und, abhängig von einem Kühlbedarf für die elektrische Antriebskomponente, steuerbar. For the operation of the traction cooling system, in principle, the function of cooling the electric drive component has priority. For example, when suddenly increased cooling demand for the electric drive component, an exhaust air mass flow can be kept unchanged despite increased performance of the fan module 3. For this purpose is in the Outgoing air duct 9, an air flow sensor 12 is provided, with the aid of a size of the exhaust air mass flow in the exhaust duct 9 is monitored and measurable. With the help of an air damper 13 inserted into the exhaust duct 9, the size of the exhaust air mass flow can be suitably controlled, in which a remaining free cross section of the exhaust air duct 9 is a ¬ adjustable. For this purpose, the air flap 13 is rotatably suspended and, depending on a cooling requirement for the electric drive component, controllable.
Das Lüftermodul 3 ist hinsichtlich der Drehzahl seines The fan module 3 is in terms of the speed of his
Lüfterrads 4 abhängig von einem Kühlbedarf der elektrischen Antriebskomponente gesteuert. Allgemein erfolgt diese Steue¬ rung derart, dass eine Drehzahl des Lüfterrads 4 bei erhöhtem Kühlbedarf so weit angehoben wird, dass parallel die Funktio¬ nen „Fortluftgerät" und „Traktionskühlanlage" erfüllt werden können. Sobald die Kühlanforderung der elektrischen Antriebskomponente derart hoch wird, dass sich ein zu hoher Fortluft- massenstrom ergeben würde, wird die Luftklappe 13 zur Verrin- gerung eines freien Querschnitts des Fortluftkanals 9 ange¬ steuert . Fan 4 controlled depending on a cooling demand of the electric drive component. In general, these Steue ¬ tion takes place such that a rotational speed of the fan 4 is lifted so far with increased cooling requirements that can be met parallel functionali ¬ nen "exhaust air device" and "traction cooling system". When the cooling request of the electric drive component is so high that an excessively high exhaust air would result in mass flow, the air damper 13 is driven to be ¬ Verrin- delay of a free cross section of the exhaust air duct. 9
Für das Lüftermodul 3 ist eine Mindestdrehzahl vorgegeben, die selbst bei nicht vorhandener Kühlanforderung für die elektrische Traktionskomponente anliegt. In diesem Fall wirkt die Traktionskühlanlage 1 in erster Linie als Fortluftgerät. Dazu ist der Fortluftkanal 9 derart geometrisch ausgelegt (Strömungswiderstand des Kanals) , dass die vorgegebene Min¬ destdrehzahl des Lüftermoduls ausreicht, Anforderungen der Klimatisierung des Fahrzeuginnenraums an die Klimaanlage zu erfüllen, d.h. ein dafür erforderlicher Fortluftmassenstrom wird durch das Lüftermodul 3 erzeugt. For the fan module 3, a minimum speed is specified, which is applied even when there is no cooling requirement for the electric traction component. In this case, the traction cooling system 1 acts primarily as exhaust air device. For this purpose, the exhaust air duct 9 is designed geometrically (flow resistance of the channel) that the predetermined minimum speed ¬ of the fan module is sufficient to meet requirements of the air conditioning of the vehicle interior to the air conditioning, ie a required exhaust air mass flow is generated by the fan module 3.
