Abstract
Description
Die Erfindung betrifft einen luftgekühlten Kondensator der Parallelflußbauart als Bestandteil von
Klimaanlagen in Fahrzeugen, der aus einer Vielzahl von Kondensator-Flachrohren besteht, mit
einer Vielzahl von diskreten Strömungswegen relativ kleinen hydraulischen Durchmessers und mit
zwischen den Flachrohren angeordneten Wellrippen, wobei die Flachrohre an beiden Enden in
runde oder ovale Sammler münden, an denen zumindest ein Zufluß- und ein Abflußanschluß für
das Kältemittel vorgesehen ist und bei dem zumindest einer der Sammler in seinem Inneren eine
Trennwand aufweist, um den parallelen Fluß des Kältemittels von der Kondensationszone, gebildet
durch eine oder mehrere Gruppen von Flachrohren, zur Unterkühlungszone, ebenfalls gebildet von
einer oder mehreren Gruppen von Flachrohren, zu bewirken.
Der beschriebene Kondensator ist beispielsweise aus dem EP 219 974 B1 bekannt. Solche Kondensatoren,
bei denen die diskreten Strömungskanäle für das Kältemittel mit sehr kleinen hydraulischen
Durchmessern von 0,381 bis 1,778 mm in den Flachrohren ausgebildet sind, haben
sich insbesondere im Fahrzeugbereich als Bestandteil von Klimaanlagen durchgesetzt, weil sie
sehr effizient arbeiten und kompakt sind.
Aus der DE 41 39 767 A1 ist eine Verdampfungskühlung für eine mit einem Ölkühler ausgerüstete
Brennkraftmaschine bekannt. Der dort vorhandene Kreislauf weist auch einen Kondensator auf, um
den Kühldampf zu kondensieren. Ferner befindet sich in dem Kreislauf eine Kondensatpumpe, die
das Kondensat nach dem Verlassen des Kondensators über eine Heizung zurück zur Brennkraftmaschine
fördert. Ein Teil des Kondensats wird unmittelbar hinter der Pumpe abgezweigt und dient
als Kühlmittel für einen Ölkühler, auf dessen Aufbau in der DE nicht eingegangen wurde. Damit
wird in sehr vorteilhafter Weise von der relativ niedrigen Temperatur des flüssigen Kühlmittels zur
Kühlung anderer Betriebsstoffe Gebrauch gemacht. Der Aufbau des Kondensators selbst ist hier
ebenfalls nicht beschrieben worden. Der gezeigte Kreislauf ist sehr raumgreifend und speziell auf
die Verdampfungskühlung zugeschnitten. Diese Art der Kühlung kommt aber eher selten zur Anwendung.
Zusätzlicher Stand der Technik geht aus der DE 41 00 483 C2 sowie aus dem deutschen Gebrauchsmuster
94 01 035.8 hervor.The invention relates to an air-cooled condenser of the parallel flow type as a component of air conditioning systems in vehicles, which consists of a plurality of condenser flat tubes, with a plurality of discrete flow paths of relatively small hydraulic diameter and with corrugated fins arranged between the flat tubes, the flat tubes at both ends in round or oval collectors open, at least one inflow and one outflow connection for the refrigerant is provided and in which at least one of the collectors has a partition in its interior to the parallel flow of the refrigerant from the condensation zone, formed by one or more groups of flat tubes to the supercooling zone, also formed by one or more groups of flat tubes.
The capacitor described is known for example from EP 219 974 B1. Such condensers, in which the discrete flow channels for the refrigerant with very small hydraulic diameters of 0.381 to 1.778 mm are formed in the flat tubes, have become established as a component of air conditioning systems, in particular in the vehicle sector, because they work very efficiently and are compact.
DE 41 39 767 A1 discloses evaporative cooling for an internal combustion engine equipped with an oil cooler. The circuit present there also has a condenser to condense the cooling steam. There is also a condensate pump in the circuit, which conveys the condensate back to the internal combustion engine via a heater after leaving the condenser. Part of the condensate is branched off directly behind the pump and serves as a coolant for an oil cooler, the construction of which was not dealt with in the DE. This makes very advantageous use of the relatively low temperature of the liquid coolant for cooling other operating materials. The construction of the capacitor itself has not been described here either. The circuit shown is very extensive and specially tailored to evaporative cooling. However, this type of cooling is rarely used.
Additional state of the art is evident from DE 41 00 483 C2 and from German utility model 94 01 035.8.
Die Aufgabe der Erfindung besteht darin, den Kondensator aus dem Oberbegriff so weiterzubilden, daß er zur Kühlung anderer Betriebsstoffe, z.B. Lenkhilfeöl, herangezogen werden kann und dabei weiterhin mit hoher Effizienz wirksam bleibt und seine günstige Herstellbarkeit nicht einbüßt.The object of the invention is to develop the capacitor from the preamble so that it is used for cooling other operating materials, e.g. Power steering oil, can be used while doing so remains effective with high efficiency and does not lose its cheap manufacturability.
Erfindungsgemäß ist vorgesehen, daß unmittelbar an das äußere Kondensator-Flachrohr der Unterkühlungszone
mindestens ein Flachrohr mit seiner einen Flachseite metallisch verbunden
angeordnet ist, das eine Vielzahl von Strömungskanälen aufweist deren hydraulischer Durchmesser
wesentlich größer ist als der der Kondensator-Flachrohre, wobei die andere Flachseite des
Flachrohres metallisch mit einer Wellrippe verbunden ist und daß das Flachrohr mit seinen beiden
Enden in gegenüberliegende Sammler mündet, die über die Unterkühlungszone hinaus verlängert
sind und am Ende der Unterkühlungszone je eine zusätzliche Trennwand aufweisen, um ein anderes
Medium vom Kältemittel zu trennen.
Das andere Medium ist vorzugsweise Lenkhilfeöl. Andere Betriebsstoffe sind nicht ausgeschlossen.According to the invention, it is provided that at least one flat tube is arranged with its one flat side directly connected to the outer condenser flat tube of the supercooling zone and has a plurality of flow channels, the hydraulic diameter of which is substantially larger than that of the condenser flat tubes, the other flat side of the Flat tube is metallically connected to a corrugated fin and that the flat tube ends with its two ends in opposite collectors, which are extended beyond the subcooling zone and each have an additional partition at the end of the subcooling zone to separate another medium from the refrigerant.
The other medium is preferably power steering oil. Other operating materials are not excluded.
Mit der erfindungsgemäßen Ausbildung des Kondensators wird folgendes bewirkt. Ohne Klimabetrieb,
bspw. in der kälteren Jahreszeit, wird das Lenkhilfeöl durch den Luftstrom gekühlt, der durch
die benachbarten Wellrippen strömt. Die größere Wellrippe an der einen Flachseite, wie gemäß
Anspruch 2 vorgesehen wurde, führt zu einer erhöhten Kühlwirkung. Die metallische Verbindung
des Flachrohres mit dem benachbarten Kondensator-Flachrohr trägt zur Kühlung bei, weil das darin
vorhandene Kältemittel eine relativ niedrige Temperatur aufweist. Bei höheren Außentemperaturen
wird die Klimaanlage eingeschaltet, woduch der Kondensator in Betrieb ist. Da sich das Flachrohr
am äußersten Kondensator-Flachrohr der Unterkühlungszone befindet, dort, wo sich bei Kondensatorbetrieb
die "kälteste" Stelle am Kondensator befindet, mit einer Temperatur von etwa 50°C des
Kältemittels bei einer Außentemperatur von etwa 40°C, wird für das Lenkhilfeöl ein zusätzlicher
Kühleffekt erzeugt. Dies hat damit zu tun, daß die Kühlung zwischen Flüssigkeiten effizienter ist als
eine Luftkühlung allein. Insgesamt wurde deshalb der Wirkungsgrad der Kühlung angehoben. Die
Steuerung des Klimabetriebes kann problemlos zusätzlich über die Temperatur des beispielsweise
Lenkhilfeöles erfolgen.With the design of the capacitor according to the invention, the following is effected. Without air conditioning,
For example, in the colder season, the power steering oil is cooled by the air flow through
the neighboring corrugated fins flows. The larger corrugated fin on one flat side, as per
Da die Herstellung des erfindungsgemäßen Kondensators mit dem Flachrohr für das vorzugsweise
Lenkhilfeöl im selben Herstellungsprozeß mit nur sehr geringem zusätzlichen Aufwand erfolgen
kann, entsteht durch die Erfindung eine wesentliche Senkung des Montageaufwandes für diese
Komponenten in einem Kraftfahrzeug. Im Stand der Technik werden Lenkhilfeölkühler gewöhnlich
als einzelne Rohrschleifen an von Kühlluft beströmte Stellen - also in der Nähe anderer Kühler -
placiert, was einen deutlich größeren Aufwand erfordert. Ein solches Beispiel geht aus der
DE 41 00 483 C2 hervor, die gut geeignet ist, um den wesentlichen Unterschied bzw. die wesentlichen
Vorteile zu verdeutlichen.
Selbstverständlich gehört die Zusammenfassung verschiedener Kühler zu einer Einheit zum Stand
der Technik (DE-Gbm 94 01 035.8), jedoch bringt im Fall der Erfindung diese Zusammenfassung
neben den baulichen Vorteilen auch noch die beschriebenen Vorteile im Wirkungsgrad des Wärmeaustausches,
die nicht erwartet werden konnten und die beim Stand der Technik nicht
vorhanden sind. Im Vergleich mit dem Gebrauchsmuster ist die Herstellung deutlich vereinfacht
worden, weil gemäß der Erfindung zwischen dem Kondensator-Flachrohr und dem Flachrohr für
das vorzugsweise Lenkhilfeöl keine Wellrippe vorgesehen ist. Diese Maßnahme erhöht weiterhin
die kompakte Bauweise.
Andere Merkmale ergeben sich aus den Patentansprüchen. Ferner gehen die Merkmale und ihre
Wirkungen aus der folgenden Beschreibung eines Ausführungsbeispiels hervor.

Of course, the summary of various coolers belongs to a unit of the prior art (DE-Gbm 94 01 035.8), but in the case of the invention, this summary brings besides the structural advantages also the described advantages in the efficiency of the heat exchange, which could not be expected and that are not available in the prior art. In comparison with the utility model, the production has been significantly simplified because, according to the invention, no corrugated fin is provided between the flat condenser tube and the flat tube for the preferably power steering oil. This measure further increases the compact design.
Other features emerge from the patent claims. Furthermore, the features and their effects are evident from the following description of an exemplary embodiment.
