Description

Offener Querstrom-Regenkühler auf dem Tender einer mit Kondensation arbeitenden Lokomotive. D,ie Erfindung hetrifft einen auf einem Lokomotivtender angeordneten offenen Querstrom-Regenkühler für die Rückkühlung des von einer oben flachen Kondensationsanlage benötigten Kühlwassers, wobei, von vorn gesehen, der Führerstand den Kühlkanaleintrittsquerschnitt ungefähr überdeckt. Nach der Erfindung besitzt die Kühlzone etwa die Cyleiche Länge und lichte Höhe und ist ihr Eintrittsquerschnitt wenigstens um den Betrag ,der lichten Höhe vom Führerstand der Lokoniotive entfernt.Open cross-flow rain cooler on the tender one with condensation working locomotive. The invention relates to a locomotive tender arranged open cross-flow rain cooler for the recooling of the one above flat condensation system required cooling water, whereby, seen from the front, the Driver's cab approximately covers the cooling duct inlet cross-section. According to the invention the cooling zone has approximately the same length and clear height and is its inlet cross-section at least by the amount that is clear from the driver's cab of the loconiotive.

Bei den bisher durch Druckschriften bekannt gewordenen, init Oberflächenkondensation und Rückkühlanlage ausgestatteten Dampfturbinenlokomotiven ist der Rückkühlkanal, wenn er auf einem hinter der Lokoinotiv#e angehängten Tender angeordnet war, entweder so hoch verlegt worden, daß die Luft über iden Führerstanid hinweg iin den Kühlkanal eindringen sollte, oder es wurde auf die Luftzuführung überhaupt keine besondere Sorgfalt gelegt und der Kühlkanaleintritt unmittelbar hinter dem Führerstand angeordnet. Der erstgenannte Fall kann in Wirklichkeit nur selten Anwendung finden, weil Jn der Regel das Bahnprofil eine so hohe Verlegung nicht zuläßt. Außerdem muß der Eintrittsquerschnitt des Luftkanals so niedergehalten werden, daß nicht genügend Luft in die Kühlzone gelangen kann. Im anderen Fall übt der nahe vor dem Kühlkanaleintritt befindliche Führerstand der Lokomotive eine Drosselwirkun,g aus, wodurch die tatsächlich in den Kühlkanal eintretende Luftmenge stark vermindert wird gegenülber derjenigen Menge, welche eintreten würde, wenn vor dem Kühlkanal kein Hlindernis vorhanden wäre.In the case of surface condensation, which has become known so far from publications and recooling system equipped steam turbine locomotives is the recooling duct, if it was arranged on a tender attached behind the Lokoinotiv # e, either has been moved so high that the air over the driver's cab into the cooling duct should penetrate, or there was no special at all on the air supply Care was taken and the cooling duct inlet arranged directly behind the driver's cab. The former case can only rarely be used in reality because Jn As a rule, the track profile does not allow such a high installation. In addition, the inlet cross-section must of the air duct must be held down so that not enough air enters the cooling zone can get. In the other case, the one located close to the inlet of the cooling channel exercises The driver's cab of the locomotive has a throttle effect, which actually causes the in the amount of air entering the cooling duct is greatly reduced compared to that Amount that would occur if there were no obstacles in front of the cooling channel were.

Diesen Nachteilen soll vorliegende Erfindungabhelfen. Die Zeichnung zeigt ein Ausführungsbeispiel. L ist der hintere Teil einer Dampflokomotive init dem Führerstand F. An die Lokomotive hinten angekuppelt i,st ein Tender, auf welchem ein Rückkühler R angeordnet ist. In diesein Rückkühler befindet sich ein Kühlkanal von der lichten Höhe h. Der Abstand. des Kühlkanaleintritts E von dem hinteren Ende des Führerstandes F beträgt a, und es ist a == lt. Dieser Abstand a könnte aber auch größer sein als h. Die Länge der Z KühlzoneIst 1, und diese ist etwa gleich der Höhe h des Kühlkanales. Aus der Seitenansieht :nach Abb. i und aus dein Grundriß (Abh. 2) ist ersichtlich, wie durch den verhältnismäßig großen Abstand a zwischen dein Führerstand und dein Eintritt zum Rückkühlkanal es einer großen Luftinenge möglich ist, in iden,Kanal einzutreten. Damit diese Luftmenge alsdiann auf das im Kanal von oben nach unten fallende, zu kühlende Wasser eine möglichst große Kühlwirkung ausübt, wird t' ZD ,die Länge 1 etwa gleich groß gehalten als die lichte Höhe h. Würde sie jedoch noch erheblich größer gehalten, so würd!e sich die Tenrlerlange allzusehr vergrößern.The present invention is intended to remedy these disadvantages. The drawing shows an embodiment. L is the rear part of a steam locomotive with the driver's cab F. Coupled to the rear of the locomotive is a tender on which a dry cooler R is arranged. In this one recooler there is a cooling duct with a clear height h. The distance. of the cooling duct inlet E from the rear end of the driver's cab F is a, and it is a == lt. However, this distance a could also be greater than h. The length of the Z cooling zone is 1, and this is approximately equal to the height h of the cooling channel. From the side view: according to Fig. I and from your floor plan (Abh. 2) it can be seen how the relatively large distance a between your driver's cab and your entrance to the recooling duct makes it possible for a large amount of air to enter the duct. So that this amount of air then exerts the greatest possible cooling effect on the water to be cooled falling from top to bottom in the channel, t 'ZD, the length 1, is kept approximately the same as the clear height h. If, however, it were kept considerably larger, the length would increase too much.
