Gelötete Kondensatoren für Kraftfahrzeugklimaanlagen bestehen aus einem Kondensatornetz und beiderseits des Netzes angeordneten Sammelrohren, die einen Kältemitteleinlass und einen Kältemittelauslass für eine Kältemittelzufluss- und eine Kältemittelabflussleitung aufweisen. Um den Kondensator im Fahrzeug zu befestigen, sind an den Sammelrohren oder auch an den Seitenpartien des Kondensators (zwischen den Sammelrohren) Halteelemente befestigt, z. B. in Form von Halteblechen mit Ösen oder Haltezapfen zur Abstützung in einem zugeordneten fahrzeugseitigen Lager. Meistens wird der Kondensator vor einem Kühlmittelkühler des Fahrzeuges angeordnet und an diesem direkt befestigt. Die Kältemitteleitungen des Kondensators, die aus Aluminiumrohr bestehen, werden am Kondensator befestigt, wozu so genannte Rohrhalter vorgesehen sind, die ebenfalls mit dem Kondensator verlötet oder an diesem anderweitig befestigt sind. Dabei handelt es sich bei den Halteelementen zur Abstützung oder Aufhängung des Kondensators und den Rohrhaltern zur Befestigung der Kältemittelleitungen jeweils um separate Bauteile, die einzeln hergestellt werden und an getrennten Stellen am Kondensator angeordnet sind. Beispielsweise geht eine solche Anordnung von Haltelementen und Rohrhaltern aus der älteren Anmeldung mit dem Aktenzeichen EP 03290190.2 hervor, wobei der Kondensator "in einem Schuss" mit den Haltern und den Rohrhaltern gelötet wird. Durch die DE 196 45 502 A1 wurde ein Kondensator mit Haltern zur Abstützung bekannt, welche am Netz des Kondensators durch Nieten befestigt sind.Soldered capacitors for motor vehicle air conditioners consist of a Condenser network and collecting pipes arranged on both sides of the network a refrigerant inlet and a refrigerant outlet for a refrigerant inflow and a refrigerant outflow line. To the capacitor to be mounted in the vehicle are at the headers or even at the side parts of the condenser (between the headers) holding elements attached, z. B. in the form of retaining plates with eyelets or retaining pin for support in an associated vehicle-mounted bearing. Mostly the condenser is placed in front of a coolant radiator of the vehicle and directly attached to this. The refrigerant lines of the condenser, made of aluminum tube are attached to the condenser, what are called tube holders are provided, which also with the capacitor soldered or otherwise attached to this. It acts it is the retaining elements for supporting or suspending the capacitor and the pipe holders for fixing the refrigerant pipes respectively separate components that are manufactured individually and on separate Positions are arranged on the capacitor. For example, such is one Arrangement of holding elements and pipe holders from the earlier application with the file number EP 03290190.2, wherein the capacitor is soldered "in one shot" with the holders and tube holders. By DE 196 45 502 A1 was a capacitor with holders for support known, which are attached to the network of the capacitor by riveting.

Durch das Gebrauchsmuster DE 295 09 565 U1 der Anmelderin wurde ein gelöteter Wärmeübertrager in Form eines Kondensators bekannt, bei welchem die Halter zur Abstützung oder Aufhängung des Kondensators formund stoffschlüssig mit den Sammelrohren verbunden sind. Dadurch ist ebenfalls eine Lötung in einem Arbeitsgang und ohne zusätzliche Löthilfsmittel möglich.By the utility model DE 295 09 565 U1 the Applicant was a soldered heat exchanger in the form of a capacitor known in which the holder for supporting or suspending the capacitor form and cohesively connected to the headers. This is also a soldering in one operation and without additional soldering aids possible.

Es ist Aufgabe der vorliegenden Erfindung, einen Kondensator der eingangs genannten Art, d. h. mit unterschiedlichen Haltern zu vereinfachen, die Herstellung zu erleichtern und die Kosten zu reduzieren.It is an object of the present invention to provide a capacitor of the initially mentioned type, d. H. with different holders to simplify the manufacture facilitate and reduce costs.

Diese Aufgabe wird durch die Merkmale des Patentanspruches 1 gelöst. Erfindungsgemäß ist vorgesehen, dass die am Kondensator befestigten Halteelemente so gestaltet sind, dass sie zwei unterschiedliche Funktionen ausüben können, nämlich erstens die der Abstützung oder Aufhängung des Kondensators und zweitens die der Halterung einer Kältemittelleitung. Damit wird der Vorteil erreicht, dass die Zahl der Teile, insbesondere der Halteteile verringert und die Herstellung vereinfacht wird. Damit reduzieren sich auch die Kosten des Kondensators. Beispielsweise benötigt der erfindungsgemäße Kondensator statt - wie beim Stand der Technik - eines Haltelementes und eines Rohrhalters, die beide am Kondensator verlötet werden, nur noch ein erfindungsgemäßes Kombinationshalteelement, welche beide Funktionen gleichzeitig ausübt.This object is solved by the features of claim 1. According to the invention it is envisaged that the retaining elements attached to the capacitor are designed so that they have two different functions First, that of the support or suspension of the Condenser and second, the holder of a refrigerant pipe. In order to the advantage is achieved that the number of parts, especially the holding parts reduced and the production is simplified. This also reduces the cost of the capacitor. For example, the invention requires Capacitor instead - as in the prior art - a holding element and a tube holder, both of which are soldered to the capacitor, only an inventive combination retaining element, which both functions exercises simultaneously.
