Die vorliegende Erfindung betrifft einen Plattenkühler für Flüssigkeiten, insbesondere Hydrauliköl, mit einem parallelepipedischen Paket aus beabstandeten, Flüssigkeitskanäle bildenden Platten, wobei zwischen benachbarten Flüssigkeitskanälen Luftlamellen zwischengeschaltet sind und die Flüssigkeitskanäle endseitig mit Flüssigkeitsverteilerkanälen in Verteilerkästen in 5 Verbindung stehen, die mit Zu- und Ableitungen versehen sind.The present invention relates to a plate cooler for liquids, in particular hydraulic oil, with a parallelepipedic packet of spaced, fluid channels forming plates, wherein intermediate air channels are interposed between adjacent fluid channels and the liquid channels end with liquid distribution channels in distribution boxes in connection 5, which provided with inlets and outlets are.

Bei bekannten Plattenkühlern dieser Art sind die an den Enden der Flüssigkeitskanäle vorgesehenen Verteilerkästen, die mit den Flüssigkeitsanschlüssen versehen sind, zusätzlich von einer Bypass-Rohrleitung überbrückt, die außerhalb des Kühlers verläuft und im kalten Zustand des io Öles einen Durchfluß gestattet. Diese Ausführung ist konstruktiv aufwendig und erhöht den Raumbedarf für den Kühlereinbau.In known plate coolers of this type, the provided at the ends of the liquid channels distribution boxes, which are provided with the liquid connections, additionally bridged by a bypass pipe, which extends outside the radiator and in the cold state of the oil io allows a flow. This design is structurally complex and increases the space required for the radiator installation.

Die Erfindung zielt darauf ab, diese Mängel zu vermeiden und einen Plattenkühler der einleitend angegebenen Art zu schaffen, der auf konstruktiv einfache Weise aufgebaut und angeschlos-15 sen werden kann sowie im Kaltzustand eine Bypass-Strömung ohne äußere Rohrleitung ermöglicht. Der erfindungsgemäße Plattenkühler zeichnet sich dadurch aus, daß in dem Paket parallel zu den Flüssigkeitskanälen Bypass-Kanäle zwischen den Verteilerkästen verlaufen und der auf der Flüssigkeitszulaufseite vorgesehene Verteilerkasten im Bereich der Bypass-Kanäle mit einem Ventil ausgestattet ist, das die Verbindung zwischen dem Verteilerkanal und den Bypass-20 Kanälen im Kaltzustand gestattet.The invention aims to avoid these shortcomings and to provide a plate cooler of the type described in the introduction, which can be constructed in a structurally simple manner and can be connected up and, in the cold state, allows a bypass flow without an external pipeline. The plate cooler according to the invention is characterized in that pass in the package parallel to the liquid channels bypass channels between the distribution boxes and provided on the liquid inlet side distribution box is provided in the region of the bypass channels with a valve which the connection between the distribution channel and the Bypass 20 channels allowed in cold condition.

Bei einer Ausführungsform der Erfindung ist der Ventilverschlußkörper durch eine Feder in die Schließstellung vorgespannt, vorzugsweise bis zu einer Druckdifferenz von 2-3 bar (Öffnungsdruck). 25In one embodiment of the invention, the valve closure body is biased by a spring in the closed position, preferably up to a pressure difference of 2-3 bar (opening pressure). 25

Die Erfindung ermöglicht vorteilhaft, daß im Normalbetrieb, wenn das Öl warm und der Druckverlust über die Flüssigkeitskanäle klein (&lt; 2 bar) ist, der Bypass verschlossen ist und die gesamte Ölmenge über die Flüssigkeitskanäle strömt. Ist im Kaltbetrieb der Druckverlust in den Flüssigkeitskanälen &gt; 2-3 bar, so öffnet das Bypassventil und ermöglicht die direkte Verbindung 30 zwischen den Verteilerkanälen über die Bypasskanäle.Advantageously, in normal operation, when the oil is warm and the pressure loss across the fluid passages is small (<2 bar), the invention advantageously allows the bypass to be closed and the entire amount of oil to flow across the fluid passages. If, during cold operation, the pressure loss in the liquid channels is &gt; 2-3 bar, so opens the bypass valve and allows the direct connection 30 between the distribution channels via the bypass channels.

Weitere Merkmale und Vorteile der Erfindung gehen aus der nachfolgenden Beschreibung einer bevorzugten Ausführungsform unter Bezugnahme auf die Zeichnungen hervor, in denen zeigen: Fig. 1 einen Vertikalschnitt durch den Plattenkühler gemäß der Erfindung und Fig. 2 im Vertikal-35 schnitt ein Detail des Plattenkühlers nach Fig. 1.Further features and advantages of the invention will become apparent from the following description of a preferred embodiment with reference to the drawings, in which: Fig. 1 shows a vertical section through the plate cooler according to the invention and Fig. 2 in vertical 35 cut a detail of the plate cooler after Fig. 1.

Gemäß den Zeichnungen weist der aus Aluminium oder einer Aluminiumlegierung gebildete Plattenkühler für Flüssigkeiten, insbesondere Hydrauliköl, ein zwischen einer Endplatte 1 und einer Endplatte 2 angeordnetes parallelepipedisches Paket 3 aus beabstandeten Platten 4 auf, 40 wobei jeweils durch zwei beabstandete Platten 4 und dazwischen angeordnete gesonderte Seitenplatten 5 und Endplatten 6 Flüssigkeitskanäle 7 gebildet sind. Die Flüssigkeitskanäle 7 stehen endseitig mit Flüssigkeitsverteilerkanälen 8, 8' in Verbindung, die zu Zu- und Ableitungen 14, 14' führen, welche beispielsweise durch Eckverbinder 9, 9' gebildet sind. Zwischen benachbarten Flüssigkeitskanälen 7 sind Luftlamellen 10 zwischengeschaltet. Die anderen 45 Öffnungen 11, 12 der Verteilerkanäle sind durch nicht gezeigte Stopfen verschlossen.According to the drawings, the plate cooler for liquids, in particular hydraulic oil, formed of aluminum or an aluminum alloy has a parallelepipedic packet 3 of spaced plates 4 arranged between an end plate 1 and an end plate 2, each with two spaced plates 4 and separate side plates arranged between them 5 and end plates 6 fluid channels 7 are formed. The liquid channels 7 are at the end with liquid distribution channels 8, 8 'in connection, leading to supply and discharge lines 14, 14', which are formed for example by corner connectors 9, 9 '. Between adjacent fluid channels 7 air louvers 10 are interposed. The other 45 openings 11, 12 of the distribution channels are closed by plugs, not shown.

Die Verteilerkanäle 8, 8' sind jeweils in einem Verteilergehäuse 13, 13' ausgebildet. Gemäß Fig. 2 ist in einer Trennwand 18 des Gehäuses 13 ein Gewindesitz 18' für ein Verschlußventil 15 ausgebildet, welches im Normalbetrieb im Kaltzustand des Öls den oberen Verteilerkanal 8 so mit Bypass-Kanälen 16 in Verbindung setzt, so daß das Öl auch durch die parallel zur Endplatte 2 zu dem anderen Verteilerkanal 8' führenden Bypass-Kanäle 16 strömt. Bei einer Druckdifferenz kleiner 2-3 bar schließt das Ventil 15, so daß das Öl nur über die Flüssigkeitskanäle 7 zwischen den Verteilerkanälen 8, 8' strömt. 55 Das Ventil 15 ist mit einer Halterung 17 in eine Aufnahme der Trennwand 18 des oberen Vertei-The distribution channels 8, 8 'are each formed in a distributor housing 13, 13'. 2, a threaded seat 18 'is formed for a closure valve 15 in a partition wall 18 of the housing 13, which sets the upper distribution channel 8 so with bypass channels 16 in normal operation in the cold state of the oil, so that the oil through the parallel to the end plate 2 to the other distribution channel 8 'leading bypass channels 16 flows. At a pressure difference smaller than 2-3 bar, the valve 15 closes, so that the oil flows only through the fluid channels 7 between the distribution channels 8, 8 '. 55 The valve 15 is provided with a holder 17 in a receptacle of the partition 18 of the upper distribution.
