Description

Die Erfindung betrifft einen Kältemittelkondensator, insbesondere für eine Klimaanlage eines Kraftfahrzeuges nach dem Oberbegriff des Patentanspruches 1 - bekannt durch die FR-A 2.757.610.The invention relates to a refrigerant condenser, in particular for a Air conditioning system of a motor vehicle according to the preamble of claim 1 - known from FR-A 2,757,610.

Kältemittelkondensatoren sind bekannte Komponenten von Kältemittelkreisläufen für Kraftfahrzeug-Klimaanlagen. Das Kältemittel tritt als überhitzter Dampf unter hohem Druck in den Kondensator ein und wird dort unter Abgabe von Wärme an die Umgebungsluft kondensiert, wobei teilweise auch eine Unterkühlung des Kältemittels vor Austritt aus dem Kondensator vorgesehen ist. Eine weitere Komponente des Kältemittelkreislaufes ist ein so genannter Sammler oder Sammelbehälter, der einerseits als Speicher und andererseits als Filter und/oder Trockner für das Kältemittel dient. Es sind im Wesentlichen zwei Bauarten bekannt, bei welchen der Sammler entweder mit dem Kondensator zu einer Baueinheit integriert ist oder ein separates Teil zum Kondensator bildet. Der integrierte Sammler wurde durch zahlreiche Druckschriften der Anmelderin bekannt, z. B. die DE-A 42 38 853, die DE-A 43 19 293 und die DE-A 198 48 744. Bei diesen Bauarten ist der Sammler parallel zu einem der beiden Sammelrohre des Kondensators angeordnet und über Kältemitteldurchlassöffnungen mit dem Sammelrohr verbunden. Diese Bauweise ist zwar sehr kompakt, jedoch unter bestimmten Einbaubedingungen nicht immer die günstigste Lösung. In solchen Fällen kann ein separater oder externer Sammler vorteilhafter sein. Refrigerant condensers are known components of refrigerant circuits for automotive air conditioning systems. The refrigerant occurs as overheated Steam under high pressure in the condenser and is there under levy condensed by heat to the ambient air, sometimes also a Subcooling of the refrigerant is provided before exiting the condenser is. Another component of the refrigerant circuit is a so-called Collector or collecting container, on the one hand as a memory and on the other hand serves as a filter and / or dryer for the refrigerant. They are essentially two designs known in which the collector either with the Capacitor is integrated into a unit or a separate part to Capacitor forms. The integrated collector was through numerous pamphlets the Applicant known, z. For example, DE-A 42 38 853, DE-A 43 19 293 and DE-A 198 48 744. In these types of collector is parallel arranged to one of the two manifolds of the capacitor and over Refrigerant passage openings connected to the manifold. This construction Although very compact, but under certain installation conditions not always the cheapest solution. In such cases, a separate or external collectors be more advantageous.

Durch die FR-A 2 757 610 wurde ein solcher Kondensator mit separatem Sammler bekannt, der über Kältemittelleitungen mit einem von zwei Sammelrohren des Kondensators verbunden ist. Letzterer ist mehrflutig durchströmt und weist daher durch Trennwände abgeteilte Kammern auf, die hintereinander durchströmt werden, wobei vor Austritt des Kältemittels aus dem Kondensator eine so genannte Unterkühlstrecke vorgesehen ist, in welcher das Kältemittel unter die Kondensationstemperatur abgekühlt wird. Das Kältemittel wird vor Eintritt in die Unterkühlstrecke über eine Kältemittelabsaugleitung dem Sammler und über eine Kältemittelzuführleitung der Unterkühlstrecke bzw. der ihr zugeordneten Kammer zugeführt. Der Sammelbehälter weist einen Boden und einen Deckel auf, wobei zwischen Boden und Deckel eine Filtereinheit angeordnet ist. Sowohl der Kältemitteleinlass als auch der Kältemittelauslass für beide Anschlussleitungen sind im Deckel angeordnet. Das Kältemittel durchströmt das Filter von oben nach unten, gelangt in den unteren Bereich des Sammlers, strömt dann durch ein das Filter durchsetzendes Steigrohr wieder nach oben und gelangt schließlich durch die Kältemittelzuführleitung vor die Unterkühlstrecke. Nachteilig bei dieser bekannten Bauweise ist das Steigrohr, welches praktisch die gesamte Höhe des Sammelbehälters durchsetzt, was zu einer relativ langen Kältemittelrücklaufleitung zum Sammelrohr führt und einen erhöhten Druckabfall bedeutet.By FR-A 2,757,610 such a capacitor with separate Collector known about refrigerant pipes with one of two header pipes the capacitor is connected. The latter is flowed through with multiple flooding and therefore has partition walls partitioned chambers, one behind the other be flowed through, wherein before the exit of the refrigerant from the Condenser is provided a so-called subcooling, in which the refrigerant is cooled below the condensation temperature. The refrigerant before entering the subcooling section via a refrigerant suction line the collector and a Kältemittelzuführleitung the subcooling or the chamber assigned to it. The collection container has a bottom and a lid, wherein between bottom and Cover a filter unit is arranged. Both the refrigerant inlet as also the refrigerant outlet for both connecting lines are arranged in the cover. The refrigerant flows through the filter from top to bottom, passes in the bottom of the collector, then flows through a filter piercing riser back up and finally passes through the refrigerant supply line in front of the subcooling section. A disadvantage of this known construction is the riser, which is virtually the entire height the collection container interspersed, resulting in a relatively long refrigerant return line leads to the manifold and means an increased pressure drop.

Es ist Aufgabe der vorliegenden Erfindung, einen Kältemittelkondensator der eingangs genannten Art konstruktiv zu verbessern, insbesondere hinsichtlich der Kältemittelanschlüsse.It is an object of the present invention to provide a refrigerant condenser constructively to improve the type mentioned above, in particular with regard the refrigerant connections.

Diese Aufgabe wird durch die Merkmale des Patentanspruches 1 gelöst. Erfindungsgemäß ist vorgesehen, dass der Kältemittelauslass im Boden des Sammelbehälters angeordnet ist und von dort direkt zum Kondensator führt. Damit werden ein Steigrohr und ein langer Kältemittelrücklauf hinfällig. Daraus ergeben sich Gewichts- und Kostenvorteile sowie ein geringerer Druckabfall für diese aus Sammelbehälter und Kondensator bestehende Baueinheit. This object is solved by the features of claim 1. According to the invention is provided that the refrigerant outlet in the bottom of Collecting container is arranged and leads from there directly to the capacitor. Thus, a riser and a long refrigerant return are obsolete. from that There are weight and cost advantages and a lower pressure drop for this assembly consisting of collecting container and capacitor.

Vorteilhafte Ausgestaltungen der Erfindung ergeben sich aus den Unteransprüchen. So ist der Kältemitteleinlass des Sammelbehälters in dessen Dekkel angeordnet und die Filter/Trocknereinheit befindet sich zwischen dem Einlass und dem Auslass, d. h. sie wird vom Kältemittel, welches hier weitestgehend kondensiert ist, von oben nach unten durchströmt. Mit diesen Anschlüssen im Boden und im Deckel ergeben sich äußerst kurze Kältemittelanschlussrohre und damit ein geringer kältemittelseitiger Druckabfall.Advantageous embodiments of the invention will become apparent from the dependent claims. Thus, the refrigerant inlet of the collecting container is in its lid arranged and the filter / dryer unit is located between the Inlet and outlet, d. H. it is from the refrigerant, which here largely condensed, flows through from top to bottom. With these Connections in the bottom and in the lid result in extremely short refrigerant connection pipes and thus a low pressure on the refrigerant side.

Nach einer weiteren vorteilhaften Ausgestaltung der Erfindung wird die Filter/Trocknereinheit nach oben und nach unten durch Lochbleche abgeschlossen und auch im Sammelbehälter gehalten. Die Lochbleche erlauben einen Durchtritt des Kältemittels und nehmen ein Granulat zur Trocknung zwischen sich auf.According to a further advantageous embodiment of the invention, the filter / dryer unit closed up and down through perforated sheets and also kept in the collection container. The perforated plates allow a passage of the refrigerant and take a granule for drying between themselves.

In weiterer vorteilhafter Ausgestaltung der Erfindung ist zwischen dem Kältemitteleinlass im Deckel und der Oberseite der Filter/Trocknereinheit eine Umlenkeinrichtung vorgesehen, die einen direkten Durchtritt des Kältemittels von oben nach unten, also ohne hinreichende Filterung und Trocknung verhindern soll. Dies kann beispielsweise durch ein unterhalb des Kältemitteleinlassquerschnittes angeordnetes Prallblech erfolgen, welches das Kältemittelkondensat radial nach außen verteilt und damit für eine gleichmäßige Durchströmung der Trockner/fFiltereinheit sorgt. Nach einer anderen vorteilhaften Ausgestaltung der Erfindung kann das Prallblech auch Teil des Lochbleches sein, in dem einige Öffnungen bzw. Poren des Lochbleches, die unterhalb des Kältemitteleinlassquerschnittes gelegen sind, verschlossen sind. Damit bildet sich somit in der Mitte des Lochbleches ein Staupunkt, der einen radialen Abfluss des Kondensats nach außen bewirkt.In a further advantageous embodiment of the invention is between the refrigerant inlet in the lid and the top of the filter / dryer unit one Diverter provided which allows a direct passage of the refrigerant from top to bottom, so without adequate filtering and drying prevent should. This can be done, for example, by a below the refrigerant inlet cross-section arranged baffle made, which is the refrigerant condensate distributed radially outwards and thus for a uniform Flow through the dryer / filter unit ensures. After another advantageous Embodiment of the invention, the baffle plate and part of the perforated plate be in which some openings or pores of the perforated plate, the are located below the refrigerant inlet cross-section, closed are. Thus forms in the middle of the perforated plate a stagnation point, the causes a radial outflow of the condensate to the outside.

In weiterer vorteilhafter Ausgestaltung der Erfindung sind Kältemitteleinlass und Kältemittelauslass koaxial zur Mittelachse des Sammlers angeordnet, wobei die Anschlussrohre vorteilhafterweise im Boden und Deckel verschraubt sind, z. B. mittels einer Flanschverbindung. Dies erlaubt eine einfache Montage und Demontage sowie Positionierung des Sammelbehälters. In a further advantageous embodiment of the invention are refrigerant inlet and refrigerant outlet disposed coaxially with the center axis of the collector, wherein the connecting pipes advantageously screwed in the bottom and lid are, for. B. by means of a flange connection. This allows a simple Assembly and disassembly and positioning of the collection container.

Nach einer vorteilhaften Weiterbildung der Erfindung ist der Sammelbehälter zwischen den vorletzten und den letzten Strömungsdurchgang, d. h. zwischen den Kondensationsbereich und die Unterkühlstrecke des Kondensators geschaltet. Damit ist sichergestellt, dass nur Kondensat, d. h. flüssiges Kältemittel in die Unterkühlstrecke gelangt und eine wirksame Unterkühlung stattfindet.According to an advantageous embodiment of the invention, the collecting container between the penultimate and the last flow passage, d. H. between the condensation area and the subcooling distance of the condenser connected. This ensures that only condensate, d. H. liquid Refrigerant enters the subcooling and effective subcooling takes place.

Ein Ausführungsbeispiel der Erfindung ist in der Zeichnung dargestellt und wird im Folgenden näher beschreiben.An embodiment of the invention is shown in the drawing and will be described in more detail below.

Der Block 2 besteht aus Flachrohren 5 und zwischen diesen angeordneten Wellrippen 6. Die Flachrohre 5 weisen beiderseits Rohrenden auf, welche in die Sammelrohre 3, 4 münden. Das Sammelrohr 3 weist eine Einlasskammer 7 mit einem Kältemitteleinlass 8 sowie eine Auslasskammer 9 mit einem Kältemittelauslass 10 auf. Zwischen beiden Kammer 7, 9 ist eine Umlenkkammer 11 angeordnet. Das Sammelrohr 4 weist drei Umlenkkammem 12, 13, 14 auf. Das durch den Kältemitteleinlass 8 eintretende Kältemittel durchströmt den Kondensator 1 insgesamt in vier Strömungsdurchgängen, wobei der obere Bereich der Kondensationsbereich und der untere zwischen den Kammern 9, 14 gelegene Bereich der Unterkühlbereich ist. Parallel zu dem Sammelrohr 4 ist ein separater Sammler oder Sammelbehälter 15 angeordnet, welcher über eine Kältemittelzuflussleitung 16 mit der Kammer 13 und eine Kältemittelrückflussleitung 17 mit der Kammer 14 des Sammelrohres 4 verbunden ist. Der Sammelbehälter 15 weist einen Boden 18 und einen Deckel 19 sowie eine Trockner/Filtereinheit 20 auf, die etwas unterhalb des Deckels 19 angeordnet ist und nach oben durch ein Lochblech 21 und nach unten durch ein Lochblech 22 abgeschlossen ist. Zwischen beiden Lochblechen 21, 22 befindet sich ein Granulat, welches der Trocknung des Kältemittels dient. Ferner können Mikrofilter zur Zurückhaltung von Verunreinigungen des Kältemittels vorgesehen sein, die jedoch nicht dargestellt sind. Das Kältemittelzuflussrohr 16 mündet in den Deckel 19 und bildet dort den Kältemitteleinlass 16a. Das Kältemittelabflussrohr 17 ist an den Boden 18 angeschlossen und bildet dort den Kältemittelauslass 17a. Kältemitteleinlass und -auslass 16a, 17a sind als Schraubverbindungen ausgebildet und vorzugsweise auf der Mittelachse des Behälters 15 angeordnet. Unterhalb des Kältemitteleinlasses 16a ist ein Prallblech 23 angeordnet, welches schematisch eine Strömungsumlenkeinrichtung darstellen soll. Alternativ zu diesem Prallblech 23 ist in dem oberen Lochblech 21 ein mittlerer Bereich 24 angeordnet, der geschlossen, d. h. kältemittelundurchlässig ist. Mit diesem undurchlässigen Bereich 24 bzw. mit dem Prallblech 23 soll eine Umlenkung des aus dem Kältemitteleinlass 16a austretenden Kondensats in der Weise bewirkt werden, dass es sich radial nach außen verteilt und nicht direkt die Filter/Trocknereinheit 20 von oben nach unten durchströmt. Unterhalb des Lochbleches 22 befindet sich ein Raum 25, der als Speichervolumen für das Kältemittel genutzt werden kann.The single figure shows a soldered capacitor 1 with a Tube / rib block 2, called block for short, and two header pipes 3, 4. The Block 2 consists of flat tubes 5 and corrugated ribs arranged between them 6. The flat tubes 5 have on both sides pipe ends, which in the Collecting pipes 3, 4 open. The collecting tube 3 has an inlet chamber 7 with a refrigerant inlet 8 and an outlet chamber 9 with a refrigerant outlet 10 on. Between the two chambers 7, 9 is a deflection chamber 11 arranged. The manifold 4 has three Umlenkkammem 12, 13, 14 on. The refrigerant entering through the refrigerant inlet 8 flows through the condenser 1 in total in four flow passages, wherein the upper area of the condensation area and the lower area between the Chambers 9, 14 located area of the subcooling area. Parallel to that Collecting pipe 4, a separate collector or collecting container 15 is arranged, which via a refrigerant supply line 16 with the chamber 13 and a refrigerant return line 17 to the chamber 14 of the manifold 4th connected is. The collecting container 15 has a bottom 18 and a Lid 19 and a dryer / filter unit 20, which is slightly below the Cover 19 is arranged and up through a perforated plate 21 and after is closed at the bottom by a perforated plate 22. Between both perforated sheets 21, 22 is a granulate, which is the drying of the refrigerant serves. In addition, microfilters can be used to retain contaminants be provided of the refrigerant, which are not shown. The refrigerant inflow pipe 16 opens into the lid 19 and forms there the Refrigerant inlet 16a. The refrigerant drain pipe 17 is at the bottom 18 connected there and forms the refrigerant outlet 17a. Refrigerant inlet and outlet 16a, 17a are formed as screw connections and preferably arranged on the central axis of the container 15. Below the Refrigerant inlet 16 a, a baffle plate 23 is arranged, which schematically should represent a Strömungsumlenkeinrichtung. Alternative to this Baffle plate 23 is disposed in the upper perforated plate 21, a central region 24, the closed, d. H. is refrigerant impermeable. With this opaque Region 24 or with the baffle plate 23 is a deflection of the condensate exiting the refrigerant inlet 16a in the manner be caused to spread radially outwards and not directly the Filter / dryer unit 20 flows from top to bottom. Below the Perforated metal 22 is a space 25, the storage volume for the Refrigerant can be used.

Die Funktion des Kondensators 1 mit separatem Sammler 15 ist die Folgende: das Kältemittel tritt in gasförmigem Zustand durch den Kältemitteleinlass 8 in den Kondensator 1 ein, durchströmt den oberen Bereich des Kondensators in abwechselnden Richtungen, d. h. von der Kammer 7 zur Kammer 12, wird dort umgelenkt, gelangt in die Kammer 11, wo es erneut umgelenkt wird und in die Kammer 13 gelangt. Dort wird das Kältemittel bzw. Kondensat über das Kältemittelzuflussrohr 16 abgezogen und dem Sammelbehälter 15 zugeführt, durchströmt diesen von oben nach unten und gelangt über die Kältemittelrückflussleitung 17 in die Kammer 14; von dort durchströmt es die Unterkühlstrecke und erreicht schließlich den Kältemittelauslass 10. Es ist offensichtlich, dass die Kaltmittelrückflussleitung 17 aufgrund ihres Anschlusses im Boden 18 nur eine geringe Länge und nur einen Krümmer aufweist. Dies vermindert den kältemittelseitigen Druckabfall.The function of the capacitor 1 with a separate collector 15 is the following: the refrigerant enters the gaseous state through the refrigerant inlet 8 in the condenser 1, flows through the upper portion of the capacitor in alternate directions, d. H. from the chamber 7 to the chamber 12, is deflected there, enters the chamber 11, where it is deflected again is and enters the chamber 13. There is the refrigerant or condensate withdrawn via the refrigerant supply pipe 16 and the collecting container 15 fed, flows through this from top to bottom and passes over the Refrigerant return line 17 into the chamber 14; from there it flows through the Subcooling and finally reaches the refrigerant outlet 10. It is obviously that the refrigerant return line 17 due to their connection in the bottom 18 has only a small length and only one elbow. This reduces the refrigerant side pressure drop.
