Abstract

The cooling radiator is used for diesel engines in which the first radiator which faces the air stream is used for cooling engine oil. The adjacent radiator is used for engine cooling water. The production of this combined radiator is simplified by using common, continuous cooling ribs for both radiators. Each separate flow path has its own heat exchanger (1, 2, 5 and 3, 4, 6). These heat exchangers are fitted closely together. These heat exchangers have common cooling ribs (7) which cover pipes of both heat exchangers. The low temp. fluid heat exchanger is arranged to face the incoming cooling air stream.

Es ist bekannt, einen Kühlerblock eines Nebenkreislaufes, beispielsweise eines Niedrigtemperaturkreises luftseitig vor den Hauptkreislaufkühler beispielsweise für einen Hochtemperaturkreis anzuordnen. Ebenso ist es bekannt, einen Schmierölkühler luftseitig vor einen Wasserkühler eines Dieselmotors zu legen. Die einzelnen Kühlerblöcke haben aber keine wärmeleitende Verbindung miteinander. Die räumliche Zuordnung der beiden Kühlerblöcke erfordert eine umständliche Haltekonstruktion für die beiden Kühlerblöcke.It is known to use a cooler block of a secondary circuit, for example a low-temperature circuit on the air side to be arranged in front of the main circuit cooler, for example for a high-temperature circuit. It is also known to place a lubricating oil cooler on the air side in front of a water cooler of a diesel engine. The individual cooler blocks but have no thermally conductive connection with each other. The spatial allocation of the two cooler blocks requires a cumbersome support structure for the two cooler blocks.

Der Erfindung liegt die Aufgabe zugrunde, einen Kühlerblock für zwei oder mehrere Kreisläufe zu schaffen, der einfach herzustellen ist, wobei die Anzahl von Kühlerblöcken in einer Kühlanlage vermindert und die Blockherstellung verbilligt wird.The invention is based on the object of creating a cooler block for two or more circuits that is simple is to be produced, the number of cooler blocks in a cooling system being reduced and block production cheaper will.

Diese Aufgabe wird nach der Erfindung bei einem Kühlerblock der eingangs erläuterten Art im wesentlichen dadurch gelöst, daß für jeden Kreislauf ein vollständiger Wärmetauscher vorgesehen ist, daß die einzelnen Wärmetauscher räumlich benachbart angeordnet sind, und daß mindestens ein Teil der Kühlrippen des Blocks als durchgehende, allen Wärmetauschern gemeinsame Kühlrippen ausgebildet sind.This object is achieved according to the invention in a cooler block of the type explained at the outset essentially in that that a complete heat exchanger is provided for each circuit, that the individual heat exchangers spatially are arranged adjacent, and that at least a part of the cooling fins of the block as continuous, all heat exchangers common cooling fins are formed.

Als Wärmetauscher für einen Kreislauf im Sinne der Erfindung ist in bekannter Weise eine Anordnung zu verstehen, bei der Rohre für ein Fluid von etwa senkrecht dazu angeordneten Kühlrippen umgeben sind, wobei diese Rohre in oberen und unteren Sammlern münden.As a heat exchanger for a circuit in the sense of the invention, an arrangement is to be understood in a known manner in of the tubes for a fluid are surrounded by cooling fins arranged approximately perpendicular thereto, these tubes in upper and lower lower collectors open.

Derartige Wärmetauscher sind für Hauptkreislaufkühler, für Nebenkreislaufkühler, für ölkühler od. dgl. bekannt. Durch die erfindungsgemäße Ausbildung wird neben dem vereinfachten Aufbau auch der Vorteil erzelt, daß die durchgehenden Rippen einen gewissen Wärmefluß von einem zum anderen Kreislauf gewährleisten. Dadurch kann z.B. bei stehender Brennkraftmaschine ein Kreislauf vom anderen warmgehalten werden, ohne übertritt eines Mediums. Bei tiefen Außenluft-, temperaturen wird beispielsweise ein Niedertemperaturkreislauf vor dem Einfrieren geschützt.Such heat exchangers are for main circuit coolers, for Auxiliary circuit cooler, od for oil cooler. Like. Known. By the inventive training is next to the simplified Construction also has the advantage that the continuous Ribs ensure a certain flow of heat from one circuit to the other. As a result, e.g. when standing Internal combustion engine one circuit can be kept warm from the other without a medium crossing over. With deep outside air, temperatures, for example, a low-temperature circuit is protected from freezing.

Bei einem erfindungsgemäß ausgebildeten Kühlerblock für Kühlwasser und Schmieröl, z.B. Getriebeöl, wird das öl vom Kühlwasser warmgehalten bzw. vorgewärmt. Durch den Wärmefluß über die gemeinsamen Rippen kann das Einstocken des Öls im Kühler vermieden werden.In a radiator block designed according to the invention for cooling water and lubricating oil, e.g. gear oil, the oil kept warm or preheated by the cooling water. Due to the heat flow over the common ribs, stocking up can occur of the oil in the cooler can be avoided.

Besonders vorteilhaft ist es, die Wärmetauscher der einzelnen Kreisläufe in Luftrichtung gesehen hintereinander anzuordnen.It is particularly advantageous to arrange the heat exchangers of the individual circuits one behind the other as seen in the air direction.
