Description

Die Erfindung betrifft einen Verteiler- bzw. Sammelkasten für einen von oben nach unten von einer Flüssigkeit durchströmten Plattenkühler, wobei der Kasten an den Enden eines parallelepipedischen Pakets aus beabstandeten Plattenkörpern des Kühlers befestigbar ist, welche vertikale Flüssigkeitskanäle und dazwischen angeordnete Luftkanäle einschließen und wobei der Kasten (als hohles, beiderends abgeschlossenes Strangpreßprofil aus Aluminium mit einem horizontalen Flüssigkeitskanal sowie mit mindestens einer Öffnung ausgebildet ist, die zu einer wegführenden Zuleitung bzw. zu einer wegführenden Ableitung führt und der Kasten nach außen offene, im Querschnitt T-förmige Führungsnuten zum Anbringen von Kühleranschlußelementen aufweist. Die Erfindung betrifft ferner einen Plattenkühler für Flüssigkeiten, insbesondere Hydrauliköl, mit einem parallelepipedischen Paket aus beabstandeten Plattenkörpern, welche vertikale Flüssigkeitskanäle und dazwischen angeordnete Luftkanäle einschließen und endseitig mit einem an ihrer oberen Begrenzung angeordneten Verteilerkasten und einem an ihrer unteren Begrenzung angeordneten Sammelkasten in Verbindung stehen, wobei der Verteilerkasten mit mindestens einer wegführenden Zuleitung und der Sammelkasten mit mindestens einer wegführenden Ableitung verbindbar ist.The invention relates to a header for a top-to-bottom liquid-cooled plate cooler, the box being attachable to the ends of a parallelepiped packet of spaced plate bodies of the cooler, including vertical fluid channels and air passages therebetween, and wherein the box (As hollow, both ends completed extruded aluminum profile with a horizontal liquid channel and at least one opening is formed, which leads to a lead-leading supply or to a derivative discharge and the box outwardly open, in cross-section T-shaped guide grooves for attaching radiator connection elements The invention further relates to a plate cooler for liquids, in particular hydraulic oil, with a parallelepipedic packet of spaced plate bodies, which vertical liquid channels and Lu arranged therebetween Include ftkanäle and end with a arranged at its upper limit distribution box and a arranged at its lower limit collecting box in communication with the distribution box with at least one lead-leading supply and the collecting box with at least one outgoing discharge line is connectable.

Bei derartigen Kühlern werden Anschlussaggregate, wie Bypassleitungen, Anschlussleitungen od.dgl. am Kühler mit Hilfe unterschiedlich gestalteter Montageelemente befestigt, was den Herstellungsaufwand für den Kühler erhöht und die Montage des Kühlers erschwert. Eine mit einem temperaturabhängigen Ventil ausgestattete Bypassleitung zwischen dem Verteilerkasten und dem Sammelkasten ist z.B. im Kaltzustand der Strömung zweckmäßig, um die für den Betrieb erwünschte Temperatur der Flüssigkeit schneller zu erreichen.In such coolers connecting units, such as bypass lines, connecting lines or the like. attached to the radiator with the help of differently designed mounting elements, which increases the manufacturing cost of the radiator and makes the installation of the radiator difficult. A bypass line provided with a temperature-dependent valve between the distribution box and the collecting box is e.g. in the cold state of the flow appropriate to achieve the desired temperature for the operation of the liquid faster.

Es ist bekannt, bei den eingangs erwähnten Kühlern die Plattenkörper als plattenförmige Strangpressprofile mit einem Hohlquerschnitt und aus Aluminium auszubilden. Die Strangpressprofile werden hierbei endseitig in Öffnungen des Verteilerkastens und des Sammelkastens eingelötet, was zwar ein ökonomisches Fertigungsverfahren darstellt, jedoch ein aufwendiges Löten unter Schutzgas (CAB) nötig macht.It is known to form the plate body in the above-mentioned coolers as plate-shaped extruded profiles with a hollow cross-section and made of aluminum. The extruded profiles are in this case in openings of the distribution box and soldered to the collection box, which, although an economical manufacturing process, but a costly soldering under inert gas (CAB) makes necessary.

Nach einem weiteren unveröffentlichten Vorschlag sind auch der Verteilerkasten und der Sammelkasten als hohle Strangpressprofile mit einem horizontalen Flüssigkeitskanal ausgebildet, wobei die Strangpressprofile seitlich Führungsnuten und an der den Plattenkörpern zugewandten Seite Aufnahmeschlitze für die ebenso als Strangpressprofile ausgebildeten Plattenkörper aufweist. Damit ist die Herstellung vereinfacht. Die seitlichen Führungsnuten sind als nach außen offene, im Querschnitt T-förmige Nuten ausgebildet, die über die gesamte Länge des Verteiler- bzw. Sammelkastens durchlaufen und dienen der Befestigung von zu montierenden Anschlussaggregaten, wie Zu- und Ableitungen, die an notwendig zur Seite hin weisenden Öffnungen des horizontalen Flüssigkeitskanals anschließen. Diese Anordnung der Öffnungen macht eine seitlich ausladende Anordnung der Anschlussaggregate notwendig, die seitlich oftmals nicht vorhandenen Platz benötigt. Außerdem können nicht alle notwendigen Anschlusseinrichtungen, wie solche für Bypassleitungen oder für zur Befestigung des Kühlers dienende Füße auf diese Weise an den Kühler angeschlossen werden, und es sind hierfür andersartige Montage- und Befestigungsmittel erforderlich.According to another unpublished proposal, the distribution box and the collecting box are designed as hollow extruded profiles with a horizontal liquid channel, wherein the extruded profiles laterally guide grooves and on the plate bodies facing side receiving slots for the also formed as extruded plate body. Thus, the production is simplified. The lateral guide grooves are formed as outwardly open, in cross-section T-shaped grooves that run through the entire length of the distribution and collection box and serve to attach to be mounted connection units, such as supply and discharge lines to necessary to the side Connect facing openings of the horizontal liquid channel. This arrangement of the openings makes a laterally projecting arrangement of the connection units necessary, which laterally often does not need space available. In addition, not all necessary connection devices, such as those for bypass lines or serving for mounting the radiator feet can be connected in this way to the radiator, and it requires this different mounting and fastening means are required.

Die US 2006/081363 A1 zeigt einen Ölkühler mit eingangsseitigen und ausgangsseitigen Sammelkästen, die außen über ihre gesamte Länge Kühlrippen von T-förmigem Querschnitt aufweisen. Im Bereich der Anschlüsse sind die Kühlrippen zu entfernen; anderswo können sie punktuell als Nuten für Befestigungswinkel verwendet werden. Darüber hinaus zeigt das Dokument alle Merkmale des Oberbegriffs von Anspruch 1.The US 2006/081363 A1 shows an oil cooler with input-side and output-side header boxes, which have externally over their entire length cooling fins of T-shaped cross-section. In the area of the connections, remove the cooling fins; Elsewhere, they can be used selectively as grooves for mounting brackets. In addition, the document shows all features of the preamble of claim 1.

Die US 6,293,011 lehrt einen Ölkühler mit eingangsseitigen und ausgangsseitigen Sammelkästen, die jeweils zwei durchgehende Vorsprünge aufweisen, die an einen Flüssigkeitsanschluß nach Festlegung seiner Position an einem der Sammelkästen zur besseren Befestigung angepreßt werden können.The US 6,293,011 teaches an oil cooler with input side and output side header boxes, each having two continuous projections which can be pressed against a fluid port after fixing its position on one of the manifolds for better attachment.

Die DE 91 02 781 U1 offenbart eine Hohlschiene zum Leiten von Flüssigkeiten, bei welcher in Längsrichtung verlaufende Flansche Andockpositionen für verschiedene mechanische Elemente, wie beispielsweise Verbinder oder Flüssigkeitsanschlüsse, bilden.The DE 91 02 781 U1 discloses a hollow rail for conducting liquids, in which longitudinally extending Flanges provide docking positions for various mechanical elements, such as connectors or fluid ports.

Die Erfindung zielt darauf ab, die Herstellung des Kühlers ausgehend von demjenigen nach dem unveröffentlichten Vorschlag weiter zu vereinfachen, weiterhin platzsparend zu gestalten und an dem Plattenkühler für verschiedene Anschlusselemente einheitliche Montage- und Befestigungsmittel bereitzustellen.The invention aims to further simplify the production of the radiator starting from the one after the unpublished proposal, continue to make space-saving and to provide uniform mounting and fastening means on the plate cooler for different connection elements.

Dies wird bei dem eingangs genannten Verteiler- bzw. Sammelkasten dadurch erreicht, daß an der Öffnung wahlweise je eines von verschiedenen Anschlußelementen in Form einer Verschlußplatte oder eines Adapterstückes mit einer mit der horizontalen Öffnung fluchtenden horizontalen Öffnung und einer Anschlußöffnung für die wegführende Zuleitung bzw. Ableitung angeschlossen ist, wobei die Verschlußplatte oder das Adapterstück mittels Schrauben an dem Kasten befestigt ist, die von oben bzw. unten in den Führungsnuten angeordnete Schraubenmuttern eingreifen.This is achieved in the aforementioned distribution or collection box characterized in that at the opening optionally one of different connection elements in the form of a closure plate or an adapter piece with a horizontal opening aligned with the horizontal opening and a connection opening for the lead-out supply or discharge is connected, wherein the closure plate or the adapter piece is secured by screws to the box, which engage from above or below in the guide grooves arranged nuts.

Gegenstand einer Ausgestaltung der Erfindung ist ferner ein Plattenkühler für Flüssigkeiten, insbesondere Hydrauliköl, mit einem parallelepipedischen Paket aus beabstandeten Plattenkörpern, welche vertikale Flüssigkeitskanäle und dazwischen angeordnete Luftkanäle einschließen, wobei die Flüssigkeitskanäle endseitig mit einem an ihrer oberen Begrenzung angeordneten erfindungsgemäßen Verteilerkasten und einem an ihrer unteren Begrenzung angeordneten erfindungsgemäßen Sammelkasten in Verbindung stehen.The object of one embodiment of the invention is further a plate cooler for liquids, in particular hydraulic oil, with a parallelepipedic package of spaced plate bodies, which include vertical fluid channels and air channels disposed therebetween, wherein the liquid channels end with a distribution box according to the invention arranged at its upper boundary and at its lower Limiting arranged collecting tank according to the invention are in communication.

Die Führungsnuten laufen zweckmäßig über die gesamte Länge des jeweiligen Kastens durch. Überdies sind die Führungsnuten vorzugsweise an der Ober- bzw. Unterseite der Kästen an deren Rändern angeordnet, wobei das Adapterstück bzw. die Verschlussplatte mittels Schrauben befestigbar ist, die von oben bzw. unten in Schraubenmuttern eingreifen, die in den Führungsnuten angeordnet sind. Das Adapterstück und die Verschlussplatte weisen zweckmäßig senkrechte Bohrungen für die Befestigungsschrauben auf.The guide grooves suitably run over the entire length of the respective box. Moreover, the guide grooves are preferably arranged on the upper or lower side of the boxes at their edges, wherein the adapter piece or the closure plate can be fastened by means of screws which engage from above or below in nuts which are arranged in the guide grooves. The adapter piece and the closure plate expediently have vertical bores for the fastening screws.

Vorteilhaft sind wahlweise verschiedene Adapterstücke mit verschiedenen, in die gewünschte Richtung weisenden Anschlussöffnungen einsetzbar. Damit sind Anschlüsse von in verschiedene Richtungen weisenden Leitungen einfach möglich.Advantageously, different adapter pieces with different, pointing in the desired direction port openings can be used optionally. This makes it easy to connect lines pointing in different directions.

Die Plattenkörper sind vorteilhaft als Strangpressprofile aus Aluminium ausgebildet.The plate body are advantageously formed as extruded aluminum.

Der Verteilerkasten und der Sammelkasten sind zweckmäßig spiegelgleich ausgebildet und fluchten beiderends seitlich mit dem Paket der Plattenkörper.The distribution box and the collecting box are expedient mirror-like design and aligned at both ends laterally with the package of the plate body.

Die Adapterstücke sind vorteilhaft ebenfalls als Strangpressprofile aus Aluminium ausgebildet und weisen einen vertikalen Flüssigkeitskanal auf, der an die horizontale Öffnung des jeweiligen Kastens anschließt, sowie einen an den vertikalen Flüssigkeitskanal anschließenden horizontalen Flüssigkeitskanal, der an die, vorzugsweise vertikale, Anschlussöffnung des Adapterstückes für eine wegführende Leitung anschließt.The adapter pieces are advantageously also formed as extruded aluminum profiles and have a vertical liquid channel, which adjoins the horizontal opening of the respective box, and a subsequent to the vertical liquid channel horizontal liquid channel to the, preferably vertical, connection opening of the adapter piece for a wegführende Line connects.

Die Adapterstücke können seitlich nach außen offene, im Querschnitt T-förmige Nuten zum Anbringen weiterer Anschlusselemente für die wegführenden Leitungen oder Rohre aufweisen.The adapter pieces may have laterally outwardly open, in cross-section T-shaped grooves for attaching further connection elements for the outgoing lines or pipes.

An den Führungsnuten des Sammlerkastens können weitere Anschlusselemente in Form von der Befestigung des Kühlers dienenden Füßen befestigbar sein.On the guide grooves of the collector box further connection elements in the form of the attachment of the radiator serving feet can be fastened.

Der Verteilerkasten und der Sammelkasten können zur Vergrößerung des Wärmeüberganges an ihrer Oberfläche als Rippenkörper ausgebildet sein und Aufnahmeschlitze für die oberen bzw. unteren Ränder der Plattenkörper aufweisen, welche die flüssigkeitsdichte Verbindung zwischen den Kästen und den Plattenkörpern, z.B. mittels eines Niedrigtemperatur-Klebeverfahrens (< 300°C), vereinfachen.The distribution box and the collection box may be formed on their surface as a rib body to increase the heat transfer and have receiving slots for the upper and lower edges of the plate body, which the liquid-tight connection between the boxes and the plate bodies, e.g. using a low-temperature bonding process (<300 ° C), simplify.

Dabei kann jedes Adapterstück mit einer an die horizontale Öffnung des Kastens ansetzbaren horizontalen Öffnung und einer Anschlussöffnung für die wegführende Leitung versehen und an den Führungsnuten des Kastens befestigbar sein.In this case, each adapter piece can be provided with an attachable to the horizontal opening of the box horizontal opening and a connection opening for the lead-out line and fastened to the guide grooves of the box.
