Ölkühler für wassergekühlte BrennkraftmaschinenOil cooler for water-cooled internal combustion engines

Die Neuerung betrifft einen Ölkühler für wassergekühlte Brennkraftmaschinen, bei dem eine Durchflußleitung für das zu kühlende öl in Verbindung mit einer Platte vorgesehen und durch ein Rohr gebildet ist, dessen Wand dem Zutritt des Kühlwassers unmittelbar ausgesetzt ist.The innovation relates to an oil cooler for water-cooled internal combustion engines, in which a flow line for the oil to be cooled is provided in connection with a plate and is formed by a pipe, the wall of which is accessible of the cooling water is directly exposed.

Die zu lösende Aufgabe besteht darin, eine besonders einfache, raumsparende und billig, z. B. nach dem Druckgießverfahren herstellbare Ausführung eines solchen Ölkühlers zu schaffen.The task to be solved is to provide a particularly simple, space-saving and cheap, e.g. B. after the die casting process to create manufacturable execution of such an oil cooler.

Zur Lösung dieser Aufgabe wird gemäß der !Teuerung eine derartige Ausgestaltung eines ölkühlers der eingangs erwähnten Art vorgeschlagen, daß das die Durchflußleitung bildende Rohr über seine ganze länge in die Platte durch Umgießen, insbesondere nach dem Druckgießverfahren derart eingebettet ist, daß es außer im Bereich seiner Ansehluß-To solve this problem, a Such a configuration of an oil cooler of the type mentioned is proposed that the flow line forming tube over its entire length in the plate by casting around, in particular by the die casting process in this way is embedded that, except in the area of its adjoining

Dabei kann das Rohr, da es an jeder Stelle von der Platte unterstützt ist, dünnwandig ausgebildet sein, was dem Wärmeübergang zugute kommt.and at a few anchoring points at least halfway over the inner surface of the panel protrudes. Since it is supported by the plate at every point, the tube can be thin-walled be designed, which benefits the heat transfer.

Als Werkstoffe für das Rohr und die Platte eignen sich besonders Aluminiumlegierungen mit guter Wärmeleitfähigkeit und nicht zu großem Wärmeausdehnungsbeiwert, z. B. eutektische Al-Si-Legierungen.Aluminum alloys with good thermal conductivity are particularly suitable as materials for the tube and the plate and not too large a coefficient of thermal expansion, e.g. B. eutectic Al-Si alloys.

Weitere Merkmale des Gegenstandes der Neuerung werden an Hand der Zeichnung erläutert, in der ein Ausführungsbeispiel dargestellt ist, und zwar in Further features of the subject of the innovation are explained with reference to the drawing, in which an embodiment is shown, namely in

In die Platte 1, welche eine öffnung des Wassermantels der Maschine abdeckt, ist das Durchlaufrohr 2 für das zu kühlende öl so eingegossen, daß es lediglich im Bereich des Zulaufes 3 und des Ablaufes 4 ganz und im Bereich von Verankerungsklötzen 5 mehr als zur Hälfte vom Plattenwerkstoff umschlossen ist. An allen übrigen Stellen ragt es zur Hälfte über die Innenfläche der Platte 1 hinaus. Der Zulauf 3 und der Ablauf 4 sind durch Bohrungen gebildet, welche das Rohr 2 nahe an seinen verschlossenen Enden anschneiden. Beide Bohrungen durchdringen die Platte 1 voll-In the plate 1, which is an opening of the water jacket of the Covering the machine, the flow tube 2 is for the one to be cooled Oil poured in so that it is only in the area of the inlet 3 and the outlet 4 completely and in the area of anchoring blocks 5 is more than half enclosed by the panel material. It protrudes in all other places half over the inner surface of the plate 1 also. The inlet 3 and the outlet 4 are formed by bores, which cut the tube 2 close to its closed ends. Both holes penetrate the plate 1 completely
