Description

Die Erfindung betrifft eine Einrichtung zum Anschließen von Rohrleitungen an den Flüssigkeitsverteiler eines Flüssigkeits-Luftkühlers gemäß dem Oberbegriff des Anspruchs 1, insbesondere eines Hydrauliköl-Luftkühlers, der üblicherweise in den Rücklauf eines Hydrauliköl-Arbeitskreises von bewegten oder stationären Anlagen eingeschaltet ist. JP 2004/162993 offenbart eine derartige Vorrichtung.The invention relates to a device for connecting pipes to the liquid distributor of a liquid-air cooler according to the preamble of claim 1, in particular a hydraulic oil-air cooler, which is usually turned on in the return of a hydraulic oil working group of moving or stationary equipment. JP 2004/162993 discloses such a device.

Die bei Hydrauliköl-Luftkühlern vom Hydrauliköl durchströmten, zu einem parallelepipedischen Paket zusammengefaßten Kühlelemente des Kühlers bestehen in der Regel aus Aluminiumplatten und -stäben, die von Luftlamellen umgeben und mit einem sich über die Oberseite und über die Unterseite des Paketes erstreckenden kastenförmigen Verteiler verbunden sind. Die Kühlelemente werden von einem angebauten Ventilator beaufschlagt.The cooling elements of the radiator, through which hydraulic oil and air coolers flow, into a parallelepipedic package generally consist of aluminum plates and rods which are surrounded by air fins and connected to a box-shaped distributor extending over the top and bottom of the package. The cooling elements are acted upon by a mounted fan.

Um zu vermeiden, daß für verschiedene Kühlermodelle unterschiedlich dimensionierte Anschlüsse auf Lager gehalten werden müssen und um den Einbau des Kühlers zu erleichtern, ist gemäß dem EP 0 983 475 B1 der parallelepipedische Verteiler der Flüssigkeitsbehandlungsvorrichtung in einem Eckbereich mit einer Abflachung versehen, in welcher ein Flüssigkeitsdurchlaß vorgesehen ist. Ferner ist ein auf diese Abflachung aufsetzbarer, im wesentlichen pyramidenförmiger hohler Adapteraufsatz vorgesehen, der eine Basis mit einem dem Flüssigkeitsdurchlaß der Abflachung entsprechenden Flüssigkeitsdurchlaß und einen Rohrleitungsanschluß in einer seiner Pyramidenseiten aufweist, der schräg nach oben weist. Dies ermöglicht es, den Adapteraufsatz mit unterschiedlicher Orientierung an der Eckabflachung derart zu montieren, daß der Rohrleitungsanschluß je nach Bedarf schräg nach oben hinten, schräg nach oben vorne oder schräg nach oben und nach der Seite weist.In order to avoid that differently dimensioned connections must be kept in stock for different radiator models and to facilitate the installation of the radiator is, according to the EP 0 983 475 B1 the parallelepipedic distributor of the liquid treatment device is provided in a corner region with a flattening, in which a liquid passage is provided. Further provided is a substantially pyramid-shaped hollow adapter attachment which can be placed on this flattening and which has a base with a fluid passage corresponding to the fluid passage of the flattening and a pipe connection in one of its pyramid sides pointing obliquely upwards. This makes it possible to mount the adapter attachment with different orientation to the Eckabflachung such that the pipe connection as required obliquely upwards back, obliquely upwards or obliquely upwards and to the side.

Ein Problem besteht bei dieser Anschlußeinrichtung und ihrem Adapteraufsatz in manchen Anwendungsfällen darin, daß die Orientierung des Rohrleitungsanschlusses unter einem Winkel zur Oberseite des Verteilers verläuft und aus einbautechnischen Gründen dafür ausreichend Raum nicht zur Verfügung steht.A problem with this connection device and its adapter attachment in some applications is that the orientation of the pipe connection is at an angle to the top of the manifold and for reasons of installation technology for sufficient space is not available.

Es ist aus der JP 2004 162993 bekannt, einen quaderförmigen Anschlußkörper mit einer L-förmigen Bohrung und einem Rohrleitungsanschluß an der Unterseite bzw. Oberseite eines vorragenden Abschnittes des Verteilers zu montieren. Eine Änderung der Ausrichtung ist dabei nicht vorgesehen. Ferner ist es aus der WO 02/068892 A2 bekannt, einen relativ kompliziert ausgebildeten Anschlußkörper in einer Ausnehmung der Kühlerstirnwand zu montieren. Auch dieser Anschlußkörper ermöglicht einen Anschluß nur in Richtung des Verteilerkanals.It is from the JP 2004 162993 it is known to mount a parallelepipedic connector body having an L-shaped bore and a pipe connection at the bottom of a projecting portion of the manifold. A change of orientation is not provided. Furthermore, it is from the WO 02/068892 A2 known to mount a relatively complicated connector body in a recess of the radiator end wall. Also, this connector body allows a connection only in the direction of the distribution channel.

Die vorliegende Erfindung zielt deshalb darauf ab, eine verbesserte Anschlußeinrichtung zu schaffen, die bei einfacher Konstruktion einen geringen Raumbedarf hat und auf einfache Weise eine Änderung der Horizontalorientierung des Anschlußkörpers ermöglicht.The present invention therefore aims to provide an improved terminal device which has a small space requirement with a simple construction and allows a simple change of the horizontal orientation of the connector body.

Gegenstand der Erfindung ist eine Anschlußeinrichtung für den parallelepipedischen Flüssigkeitsverteiler eines Flüssigkeits-Luftkühlers gemäß Anspruch 1.The invention relates to a connection device for the parallelepipedic liquid distributor of a liquid-air cooler according to claim 1.
