Description

Die Erfindung betrifft einen Kondensator für dampfförmige Stoffe, bei dem zumindest zwei einander in einer Reihenschaltung zugeordnete und von einem Kühlmittel umströmte Rohre vorgesehen sind.The invention relates to a condenser for vaporous substances, in which at least two tubes, which are assigned to one another in a series connection and flowed around by a coolant, are provided.

Ein solcher Kondensator ist bekannt. Die damit erzielbare Kondensationsleistung ist, bezogen auf das Gewicht, nur relativ gering.Such a capacitor is known. The condensation performance that can be achieved in this way is only relatively low, based on the weight.

Der Erfindung liegt die Aufgabe zugrunde, einen solchen Kondensator derart weiter zu entwikkeln, daß sich eine Verminderung des Gewichts ergibt, bezogen auf die Leistung.The invention has for its object to develop such a capacitor in such a way that there is a reduction in weight, based on the power.

Diese Aufgabe wird erfindungsgemäß bei einem Kondensator der eingangs genannten Art mit den kennzeichnenden Merkmalen von Anspruch 1 gelöst. Auf vorteilhafte Ausgestaltungen nehmen die Unteransprüche Bezug.This object is achieved with a capacitor of the type mentioned with the characterizing features of claim 1. The subclaims refer to advantageous configurations.

Bei dem erfindungsgemäßen Kondensator ist es vorgesehen, daß an der Austrittsöffnung eines jeden Rohres eine Trenneinrichtung vorgesehen ist, die eine Separierung des Restdampfes von dem Kondensat bewirkt, wobei die Trenneinrichtung mit einem Sammler zum Abführen des Kondensats verbunden ist. Der in das jeweils nächste Rohr eintretende Rest an dampfförmigem Stoff ist dadurch frei von Kondensat. Die theoretisch erreichbare Kondensatorleistung eines jeden Rohres wird dadurch nahezu erreicht. In Bezug auf die Erzielung eines bestimmten Kondensationsergebnisses ist es dadurch möglich, das Gesamtgewicht des Kondensators gegenüber gebräuchlichen Ausführungen deutlich zu vermindern.In the condenser according to the invention, it is provided that a separating device is provided at the outlet opening of each tube, which separates the residual steam from the condensate, the separating device being connected to a collector for removing the condensate. The remainder of the vaporous material entering the next pipe is thus free of condensate. The theoretically achievable condenser performance of each tube is almost achieved. With regard to the achievement of a certain condensation result, it is possible in this way to significantly reduce the total weight of the condenser compared to common designs.

Die Trenneinrichtungen können jeweils eine Prallwand umfassen, die den Austrittsöffnungen eines jeden Rohres quer zur Austrittsrichtung in einem Abstand vorgelagert sind. Aus dem Kondensat bestehende Tröpfchen werden hierdurch aufgefangen und dem Sammler problemlos zugeführt.The separating devices can each comprise a baffle, which are arranged in front of the outlet openings of each tube at a distance transversely to the outlet direction. Droplets consisting of the condensate are thereby collected and fed to the collector without problems.

Die Prallwände können nach Art von Kästen gestaltet sein, die die Austrittsöffnungen eines jeden Rohres umgreifen, wobei ein jeder Kasten im Bereich seines oberen Endes von einer Dampfaustrittsöffnung durchdrungen ist und im Bereich seines unteren Endes von dem Sammler. Selbst bei großen Strömungsgeschwindigkeiten des unter normalen Betriebsbedingungen durchgesetzten Dampfes gelingt es hierdurch, eine gute Abscheidung aller kondensierten Bestandteile zwischen den jeweils aufeinander folgenden Rohren zu erreichen. Für die Erzielung eines günstigen Leistungsgewichtes ist das von großem Vorteil.The baffle walls can be designed in the manner of boxes which encompass the outlet openings of each tube, each box being penetrated by a steam outlet opening in the region of its upper end and by the collector in the region of its lower end. Even at high flow velocities of the steam passed through under normal operating conditions, it is possible to achieve a good separation of all condensed components between the successive pipes. This is a great advantage for achieving a favorable power-to-weight ratio.

Die Sammler können durch im wesentlichen senkrecht verlaufende Kanäle gebildet sein, wobei die Kanäle am unteren Ende durch eine Leitung verbunden sind. Die Zusammenführung und die Abführung des Kondensats gestalten sich bei einer solchen Ausführung ganz besonders einfach. Ein baukastenartiger Aufbau des gesamten Kondensators empfiehlt sich aus Gründen der vereinfachten Herstellbarkeit sowie aus Gründen einer leichteren Anpaßbarkeit an die Erfordernisse des jeweiligen Anwendungsfalles.The collectors can be formed by essentially vertical channels, the channels being connected at the lower end by a line. The merging and removal of the condensate is particularly easy with such a design. A modular construction of the entire capacitor is recommended for reasons of simplicity of manufacture and for reasons of easier adaptability to the requirements of the respective application.

Bei einer Ausführung eines Kondensators, bei dem sich die Rohre im wesentlichen quer zur Fahrtrichtung eines Kraftfahrzeuges erstrecken, hat es sich als besonders vorteilhaft bewährt, wenn die am linken und am rechten Ende der Rohre vorhandenen Sammler unterseitig jeweils mit einem Sammelraum verbunden sind, wobei die beiden Sammelräume durch eine Leitung verbunden sind und wobei zwischen einem jeden Sammelraum und dem zugehörigen Sammler ein Schwimmerventil vorgesehen ist. Die beiden Sammelräume sind unter normalen Betriebsbedingungen so weitgehend mit Kondensat gefüllt, daß sich das Schwimmerventil gerade noch in Offenstellung befindet und daß die Ansaugöffnung einer durch das Kondensat zu kühlenden Einrichtung vollständig überflutet ist. Die Kühlung der Einrichtung ist hierdurch stets gewährleistet und ein kontinuierliches Nachfließen von frisch kondensiertem Kondensat in die Sammelräume gewährleistet.In one embodiment of a condenser in which the tubes extend essentially transversely to the direction of travel of a motor vehicle, it has proven particularly advantageous if the collectors present at the left and right ends of the tubes are each connected to a collecting space on the underside, the two collecting spaces are connected by a line and a float valve is provided between each collecting space and the associated collector. Under normal operating conditions, the two collecting spaces are so largely filled with condensate that the float valve is still just in the open position and that the intake opening of a device to be cooled by the condensate is completely flooded. This always ensures cooling of the device and ensures that freshly condensed condensate flows continuously into the collecting spaces.

Bei der Kurvenfahrt eines Kraftfahrzeuges kann sich die Situation ergeben, daß das in den beiden Sammelräumen enthaltene Kondensat eine fliehkraftbedingte Relativverlagerung in Richtung der Außenseite der Kurve erfährt. In dem auf dieser Seite angeordneten Sammelraum kommt es folglich zu einem Aufstau von Kondensatbestandteilen, was eine Überführung des Schwimmerventils in eine Schließstellung bedingt. Der Umfang einer entsprechenden Relativverlagerung von Kondensatbestandteilen ist hierdurch auf eine unkritische Größenordnung beschränkt. Auch unter solchen Betriebsbedingungen ist daher, unabhängig von der Größe der in Querrichtung ausgeübten Beschleunigungskräfte, stets eine zuverlässige Versorgung der durch das Kondensat zu kühlenden Einrichtung gewährleistet. Auch die Kondensationsleistung als solche erfährt in extremen Situationen keine nennenswerte Beeinträchtigung. Im schlimmsten Falle kann es zu einem gewissen Aufstau von Kondensationsbestandteilen im letzten der einander in einer Reihenschaltung zugeordneten Rohre kommen. Unter praxisüblichen Bedingungen ist das ohne weitere Bedeutung.When a motor vehicle is cornering, the situation can arise that the condensate contained in the two collecting spaces undergoes a relative displacement in the direction of the outside of the curve due to centrifugal force. Consequently, condensate constituents accumulate in the collecting space arranged on this side, which requires the float valve to be moved into a closed position. The extent of a corresponding relative displacement of condensate constituents is hereby restricted to an uncritical order of magnitude. A reliable supply of the device to be cooled by the condensate is therefore always guaranteed even under such operating conditions, regardless of the size of the acceleration forces exerted in the transverse direction. Even the condensation performance as such is not significantly impaired in extreme situations. In the worst case, there may be a certain build-up of condensation constituents in the last of the pipes assigned to one another in a series connection. Under normal conditions, this is of no further importance.

Der Gegenstand der Erfindung wird nachfolgend anhand der als Anlage beigefügten Zeichnung weiter verdeutlicht. Es zeigen:

  • Figur 1 eine beispielhafte Ausführung des erfindungsgemäßen Kondensators in einer Ansicht von vorn;
  • Figur 2 den rechten Teil eines Kondensators ähnlich der in Figur 1 gezeigten Ausführung in längsgeschnittener Darstellung;
  • Figur 3 den in Figur 2 gezeigten Teil eines Kondensators in quergeschnittener Darstellung.
The subject matter of the invention is further clarified below with the aid of the attached drawing. Show it:
  • Figure 1 shows an exemplary embodiment of the capacitor according to the invention in a view from the front;
  • Figure 2 shows the right part of a capacitor similar to the embodiment shown in Figure 1 in a longitudinal section;
  • Figure 3 shows the part of a capacitor shown in Figure 2 in a cross-sectional view.

Der in Figur 1 gezeigte Kondensator ist für eine kontinuierliche Kondensation von dampfförmigen Stoffen bestimmt, beispielsweise für das Kühlmittel einer Verbrennungskraftmaschine. Der Kondensator besteht im wesentlichen aus einem linken Gehäuseteil 10 und einem rechten Gehäuseteil 11, die untereinander durch sich beispielsweise quer zur Fahrtrichtung eines Kraftfahrzeuges erstreckende Rohre 2 verbunden sind. Die Rohre 2 sind in einem Abstand voneinander angeordnet und hierdurch frei von Kühlluft 1 umströmbar. Sie können gegebenenfalls mit zusätzlichen Kühllamellen oder ähnlichem versehen sein.The condenser shown in FIG. 1 is intended for continuous condensation of vaporous substances, for example for the coolant of an internal combustion engine. The capacitor essentially consists of a left-hand housing part 10 and a right-hand housing part 11, which are connected to one another by pipes 2 extending, for example, transversely to the direction of travel of a motor vehicle. The tubes 2 are arranged at a distance from one another and can thus flow around free of cooling air 1. You can optionally be provided with additional cooling fins or the like.

Das linke Gehäuseteil 10 ist am oberen Ende mit einer Einlauföffnung 13 für die Zuführung eines dampfförmigen Stoffes versehen, das rechte Gehäuseteil 11 mit einer am unteren Ende austretenden Entnahmeöffnung 12 für die Abführung von Kondensat. Diese Öffnung kann beispielsweise mit der Ansaugöffnung der Kühlmittelpumpe einer Verbrennungskraftmaschine verbunden sein.The left housing part 10 is provided at the upper end with an inlet opening 13 for the supply of a vaporous substance, the right housing part 11 with a discharge opening 12 emerging at the lower end for the discharge of condensate. This opening can be connected, for example, to the intake opening of the coolant pump of an internal combustion engine.

Beide Gehäuse 10, 11 sind am unteren Ende mit Sammelräumen 9 erweiterten Querschnittes versehen. Diese sind untereinander durch eine Leitung 8 verbunden. Der Flüssigkeitsspiegel des in den beiden Sammelräumen enthaltenen Kondensats vermag sich hierdurch gegenseitig auszugleichen.Both housings 10, 11 are provided with collecting spaces 9 with an enlarged cross section at the lower end. These are interconnected by a line 8. As a result, the liquid level of the condensate contained in the two collecting spaces can compensate for one another.

In Figur 2 ist das rechte Gehäuseteil teilweise in längsgeschnittener Darstellung wiedergegeben. Es wird durch ein Kunststoff-Formteil gebildet, in welches die die eigentliche Kondensation des dampfförmigen Stoffes bewirkenden, metallischen Rohre 2 einmünden. Der Austrittsöffnung der Rohre 2 ist in einem Abstand gegenüberliegend eine Prallwand angeordnet, die sich quer zur Austrittsrichtung erstreckt. Die Prallwand 5 ist mit Ansätzen versehen, wodurch sie insgesamt von kastenförmiger Gestalt ist und die Austrittsöffnungen der Rohre entsprechend umschließt. Der durch die Prallwand gebildete Kasten wird am oberen Ende durch eine Dampfaustrittsöffnung 6 durchbrochen, am unteren Ende durch den Kondensatsammler 7.In Figure 2, the right housing part is partially shown in longitudinal section. It is formed by a molded plastic part, into which the metallic tubes 2 which cause the actual condensation of the vaporous substance open. A baffle wall is arranged at a distance opposite the outlet opening of the tubes 2 and extends transversely to the outlet direction. The baffle 5 is provided with lugs, whereby it is of a box-like shape overall and correspondingly surrounds the outlet openings of the tubes. The box formed by the baffle is broken through at the upper end by a steam outlet opening 6 and at the lower end by the condensate collector 7.

Die Dampfaustrittsöffnungen sind so gestaltet, daß eine Zwangsumlenkung zum nächst folgenden Rohr zwangsläufig erfolgt. Die Kondensatsammler 4 sind durch im wesentlichen senkrecht verlaufende Kanäle gebildet, die am unteren Ende in Sammelräumen 9 münden, welche durch eine Leitung 8 untereinander verbunden sind. Zwischen den Sammelräumen 9 und den Sammlern 4 ist ein Schwimmerventil 14 angeordnet. Dieses ist so ausgebildet, daß die Verbindung zwischen dem Sammelraum 9 und dem Sammler 4 unterbrochen wird, wenn sich ein unzulässig großer Flüssigkeitsanstieg in dem entsprechenden Sammelraum 9 ergibt. Das könnte beispielsweise der Fall sein bei der Einleitung großer Beschleunigungskräfte parallel zur Richtung der Leitung 8. Sie haben somit bei dem erfindungsgemäßen Kondensator nicht mehr eine unzulässig große Absenkung des Flüssigkeitsspiegels in dem gegenüberliegenden Sammelraum 9 zur Folge. Hierdurch ist unter allen Betriebsbedingungen eine vollständige Überflutung der Ansaugöffnung 12 gewährleistet und damit zugleich eine ausreichende Versorgung der an die Ansaugöffnung 12 angeschlossenen Einrichtung.The steam outlet openings are designed so that a forced deflection to the next pipe is inevitable. The condensate collectors 4 are formed by essentially vertical channels which open at the lower end into collecting spaces 9 which are connected to one another by a line 8. A float valve 14 is arranged between the collecting spaces 9 and the collectors 4. This is designed so that the connection between the collecting space 9 and the collector 4 is interrupted if there is an impermissibly large increase in liquid in the corresponding collecting space 9. This could be the case, for example, when large acceleration forces are introduced parallel to the direction of the line 8. With the condenser according to the invention, they no longer result in an impermissibly large drop in the liquid level in the opposite collecting space 9. This ensures complete flooding of the suction opening 12 under all operating conditions and thus at the same time a sufficient supply to the device connected to the suction opening 12.

Figur 3 zeigt den Ausschnitt aus Figur 2 in quergeschnittener Darstellung. Es ist zu ersehen, daß die Prallwände kastenförmig gestaltet sind und daß die Sammler 7, bezogen auf die Rohre 2 und die Dampfaustrittsöffnungen 6, seitlich versetzt angebracht sind.FIG. 3 shows the detail from FIG. 2 in a cross-sectional illustration. It can be seen that the baffles are box-shaped and that the collectors 7, with respect to the tubes 2 and the steam outlet openings 6, are laterally offset.
