Abstract

The cooling air system has a filter (4) which works in suction, and which splits the filtered air into clean and dusty airstreams. A cooler (3) is arranged downstream of the filter. A fan (2.1,2.2,2.3) sucks air through the cooler, and a bypass pipe circumvents the cooler so as to apply suction from the fan to the filter connection for the dusty airstream, in order to remove the latter. The system may have more than one fan, and the bypass pipe may surround the cooler.

Description

Die Erfindung betrifft eine Kühlluftanlage, insbesondere für motorbetriebene Fahrzeuge, vor allem für Schienenfahrzeuge.The invention relates to a cooling air system, in particular for motor vehicles, especially for rail vehicles.

Bei Schienenfahrzeugen, die mit Verbrennungsmotoren betrieben werden, nehmen Kühlluftanlagen einen erheblichen Raum ein und haben auch ein dementsprechend hohes Gewicht. Dies gilt besonders für die Filtereinrichtung, die dem Kühler vorgeschaltet werden muß, um diesen mit sauberer Luft zu beschicken. Als Filter kommen beispielsweise Filtereinrichtungen der Farr Company in Betracht, siehe Firmen-Bulletin No. B-1800-14B, die unter dem Handelsnamen DYNAVANE vertrieben werden. Diese Filtereinrichtungen beruhen auf dem Prinzip, die zu reinigende Luft einer häufigen Umlenkung zu unterziehen, so daß eine Zerlegung in einen Reinluftstrom und in einen Staubluftstrom erfolgt. Der Staubluftstrom gelangt zu einem Staubluftkanal. Von dort muß er abgeführt werden. Hierzu ist ein besonderes Saugzuggebläse erforderlich.In rail vehicles that are operated with internal combustion engines, cooling air systems take up a considerable amount of space and are therefore very heavy. This applies in particular to the filter device, which must be connected upstream of the cooler in order to feed it with clean air. For example, filter devices from Farr Company can be used as filters, see company bulletin no. B-1800-14B, which are sold under the trade name DYNAVANE. These filter devices are based on the principle of subjecting the air to be cleaned to frequent redirection, so that it is broken down into a clean air flow and a dust air flow. The dust air flow arrives at a dust air duct. From there it has to be removed. A special induced draft fan is required for this.

Der Erfindung liegt die Aufgabe zugrunde, eine Kühlluftanlage gemäß dem Oberbegriff von Anspruch 1 derart zu gestalten, daß ihr Raumbedarf und ihr Gewicht geringer als bei konventionellen Kühlluftanlagen ist.The invention has for its object to design a cooling air system according to the preamble of claim 1 such that its space requirement and weight is less than in conventional cooling air systems.

Diese Aufgabe wird durch die Merkmale von Anspruch 1 gelöst.This object is solved by the features of claim 1.

Der Erfinder hat erkannt, daß der Ventilator, der ohnehin bei einer Kühlluftanlage vorhanden sein muß, dazu ausgenutzt werden kann, die Staubluft des Filters abzuführen. Hierzu sieht er eine Bypassleitung zwischen dem Staubluftanschluß bzw. dem Staubluftkanal des Filters und dem Ventilator vor. Somit strömt Reinluft, wie schon seither, durch den Kühler, während die Staubluft durch den Bypasskanal und durch den Ventilator der Anlage hindurchströmt. Man spart somit ein besonderes Staubluftgebläse und damit Bauraum und Gewicht. Die Anlage kann somit kleiner und leichter werden.The inventor has recognized that the fan, which must be present in a cooling air system anyway, can be used to remove the dust air from the filter. For this purpose, he provides a bypass line between the dust air connection or the dust air duct of the filter and the fan. As before, clean air flows through the cooler, while the dust air flows through the bypass duct and through the system fan. This saves a special dust blower and thus space and weight. The system can thus become smaller and lighter.

Die Erfindung hat noch einen weiteren Vorteil: Bei einer Kühlluftanlage gemäß der Erfindung tritt Staubluft durch den Ventilator der Kühlluftanlage. Dieser Ventilator ist viel größer und damit auch unempfindlicher als die bisher verwendeten Staubluftgebläse. Daher kommt es bei Anwendung der Erfindung im Hauptventilator durch die hindurchtretende Staubluft nicht zu Problemen.The invention has yet another advantage: in a cooling air system according to the invention, dust air passes through the fan of the cooling air system. This fan is much larger and therefore less sensitive than the dust blowers previously used. Therefore, there are no problems when using the invention in the main fan due to the dust air passing through.

Die Erfindung ist anhand der Zeichnung näher erläutert. Darin ist eine Unterflur-Kühlluftanlage dargestellt, und zwar in Figur 1 in einer Draufsicht, in Figur 2 in einer Ansicht von vorn und in Figur 3 in einer Seitenansicht.The invention is explained in more detail with reference to the drawing. It shows an underfloor cooling air system, specifically in FIG. 1 in a top view, in FIG. 2 in a front view and in FIG. 3 in a side view.

Die Anlage befindet sich oberhalb der Schienen - siehe Schienenoberkante 1. Sie umfaßt drei Ventilatoren 2.1, 2.2, 2.3, einen Kühler 3 und ein Filter 4. Ein Kühlluftstrom 5 wird aufgrund der Saugkraft der Ventilatoren 2.1, 2.2, 2.3 angesaugt. Er gelangt zunächst durch das Filter 4, indem er in einen Reinluftstrom und einen Staubluftstrom zerlegt wird. Der Reinluftstrom gelangt zum Kühler 3 und von dort zu den Ventilatoren 2.1, 2.2, 2.3. Der Staubluftstrom gelangt durch einen Bypasskanal 6, der um den Kühler 3 herumgeführt ist, zu den Ventilatoren 2.1, 2.2, 2.3. Es versteht sich, daß die Ventilatoren für die beiden Luftströme ausgelegt sein müssen, d.h. für den Reinluftstrom und den Staubluftstrom.The system is located above the rails - see upper rail edge 1. It comprises three fans 2.1, 2.2, 2.3, a cooler 3 and a filter 4. A cooling air flow 5 is sucked in due to the suction force of the fans 2.1, 2.2, 2.3. It first passes through the filter 4 by being broken down into a clean air flow and a dust air flow. The clean air flow reaches the cooler 3 and from there to the fans 2.1, 2.2, 2.3. The dust air flow passes through a bypass duct 6, which is led around the cooler 3, to the fans 2.1, 2.2, 2.3. It is understood that the fans must be designed for the two air flows, i.e. for the clean air flow and the dust air flow.

Wie man sieht, verläuft die Fahrtrichtung 7 senkrecht zum Kühlluftstrom 5.As can be seen, the direction of travel 7 runs perpendicular to the cooling air flow 5.

Figur 4 zeigt schematisch den Aufbau des Filters 4. Dieses umfaßt eine Vielzahl von Deflektoren 4.1, eine Trennplatte 4.2 sowie einen Sammelkanal 4.3 für Staubluft. Die Deflektoren 4.1 bilden miteinander abgewinkelte Kanäle, durch welche die Reinluft austritt. Der Staubluftkanal 4.3 ist, wie oben erwähnt, über die Bypassleitung 6 an die drei Ventilatoren angeschlossen.Figure 4 shows schematically the structure of the filter 4. This includes a plurality of deflectors 4.1, a separating plate 4.2 and a collecting duct 4.3 for dust air. The deflectors 4.1 form angled channels, through which the clean air exits. As mentioned above, the dust air duct 4.3 is connected to the three fans via the bypass line 6.
