     Auf einem Lokomotivtender angeordneter Querstrom-Regenk#hler.   



   Die Erfindung betrifft einen auf einem    Lokomotivtender angeordneten Querstrom- Regenk#hler f#r die R#ckk#hlung des von    einer   Oberflächen-Kondensationsanlage    be   nötigten Kühlwassers, wobei, von vorn ge-    sehen,   der F#hrerstand den K#hlkanal-Ein-       trittsquerschnitt ungef#hr #berdeckt. Nach    der   Erfindung ist der Abstand des K#hl-       kanaleintrittes vom F#hrerstand der Lokomotive wenigstens gleich der lichten H#he des K#hlkanals. Dabei kann die L#nge des K#hlkanals etwa gleich dessen lichter H#he ausgef#hrt werden.   



     Bei    den bisher durch Druckschriften be   kannt gewordenen, mit Oberfl#chenkondensation und R#ckk#hlanlage ausgestatteten Dampfturbinen-Lokomotiven igt der Rück-      k#hlkanal, wenn    er auf einem hinter der    Lokomotive angehängten Tender angeordnet    war, entweder so   hoch verlegt worden, dass    (lie Luft   über den rührerstand hinweg    in den   K#hlkanal eindringen    sollte, oder es   kurde      auf die Luftxuführung überhaupt keine    besondere   Sorgfaltgelegt,undder'Kühlkanal-    eintritt   unmittell)      hinter dem Fuhrerstand    angeordnet.

   Der erstgenannte Fall kann in Wirkliehkeit nur selten Anwendung finden,   iveil    in der Regel das Bahnprofil eine so    hohe Verlegung nicht zul##t. Au#erdem mu#    der Eintrittsquerschnitt des Luftkanals so nieder   gehalten werden, dass nicht genügend    Luft in   (lie      K#hlzone gelangen kann.

   Im an-    dern   iilt    der nahe   vol      dem K#hlkanal-       cintrittbct'indlielteFübrerstandderLoko-    motive eine Drosselwirkung aus, wodurch die   tats#chlich    in   den K#hlkanal eintretende       Luftmenge stark vermindert wird, gegen#ber derjenigen Menge, welche eintreten w#rde, wenn vor dem K#hlkanal kein Hindernis vorhanden w#re.   



     Diesel    Nachteilen Na   vorliegende Erfin-    dung abhelfen.



      Die Zeichnung zeigt. ein Ausf#hrungs-    beispiel. L ist der hintere Teil einer Dampf   Lokomotive mit dem F#hrerstand F. An die    Lokomotive hinten angekuppelt ist ein   Ten-      der, auf welchem ein R#ckk#hler R angeord-    net ist.

   In diesem   R#ckk#hler      befindet sicli    ein   K#hlkanal    von der   lichten H#he h.    Der   Abstand des K#hlkanaleintrittes    E von dem    hintern Ende des F#hrerstandes F betr#gt a,    und es ist a = h.   Dieser Abstand   konnte      aber auch gr##er    sein   als .    Die   L#nge    der   K#hlzone ist l, und diese ist etwa gleich der H#he h des K#hlkanals.

   Aus der Seiten-    ansicht   lit      Fig. 1 und aus dem Grundri#     (Fit   2)    ist ersichtlich, wie durch den ver  h#ltnism##ig gro#en Abstand a zwischen oben F#hrerstand und dem Eintritt zum R#ckk#hlkanal es einer gro#en Luftmenge m#glich    ist, in den Kanal einzutreten.

     Cross-flow rain cooler arranged on a locomotive tender.



   The invention relates to a cross-flow rain cooler arranged on a locomotive tender for recooling the cooling water required by a surface condensation system, with the driver's cab opening the cooling duct when viewed from the front - step cross-section roughly covered. According to the invention, the distance of the cooling channel inlet from the driver's cab of the locomotive is at least equal to the clear height of the cooling channel. The length of the cooling duct can be made about the same as its clear height.



     In the steam turbine locomotives with surface condensation and recooling systems that have become known from publications, the recooling duct, if it was arranged on a tender attached behind the locomotive, was either laid so high that (Let air penetrate through the stirrer stand into the cooling duct, or no special care was taken at all on the air supply and the cooling duct inlet in the middle) is arranged behind the driver’s stand.

   The first-mentioned case can only rarely be used in reality; the rail profile usually does not allow such a high installation. In addition, the inlet cross-section of the air duct must be kept so low that not enough air can get into the cooling zone.

   On the other hand, when the locomotives come in close to the cooling duct, there is a throttling effect, as a result of which the actual amount of air entering the cooling duct is greatly reduced compared to the amount that would enter if there were no obstacles in front of the cooling duct.



     The present invention remedies these disadvantages.



      The drawing shows. an exemplary 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 cooler R is arranged.

   In this cooler there is a cooling duct of the 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 = h. This distance could also be greater than. The length of the cooling zone is 1, and this is approximately equal to the height h of the cooling channel.

   From the side view lit Fig. 1 and from the plan (Fit 2) it can be seen how the relatively large distance a between the top of the driver's cab and the entrance to the return cooling duct a large amount of air is able to enter the duct. So that this amount of air then flows as much as possible on the water to be cooled, which falls from top to bottom in the canal, the length of the pond is kept as high as the clear height h. If it were kept considerably larger, the length of the tender would increase too much.
