Aus der DE-OS 32 10 114 ist ein Wärmetauscher, insbesondere ein Kühler für Kraftfahrzeuge bekannt. Dieser Wärmetauscher besteht aus mehreren parallel zueinander angeordneten Rohren zur Führung des Wärmetauschmittels. Diese Rohre münden in einen oberen und in einen unteren Wasserkasten. Der Wärmetauscher besteht ferner aus lamellenartig und senkrecht zu den Rohren angeordneten plattenförmigen Wärmetauschrippen, die mit den Rohren fest verbunden sind.The invention relates to a heat exchanger, in particular an oil cooler for internal combustion engines, according to the preamble of claim 1. Such a heat exchanger is known from WO-A-95/00 810. DE-OS 32 10 114 is a heat exchanger, in particular a Radiator known for motor vehicles.

Diese Wärmetauschrippen sind an ihren Stirnkanten mit umgebogenen Endteilen versehen, die schuppenartig übereinandergelegt sind und somit Seitenteile bilden an denen Befestigungseinrichtungen für Winkel angeordnet werden können. Der bekannte Wärmetauscher der mit relativ einfachen Elementen aufgebaut ist und eine gute Wärmeübertragung aufweist hat den Nachteil, daß zum Befestigen des Wärmetauschers an einem Träger zusätzliche Winkel erforderlich sind. Außerdem sind die Anschlüsse für das Wärmetauschmittel in den oberen und unteren Wasserkasten festgelegt und nicht variabel.These heat exchange fins are bent at their front edges Provide end parts, which are superimposed like a scale and thus form side parts on which fastening devices for Angle can be arranged.
