Description

Verfahren zum Verbinden von Teilen aus gleichen oder verschiedenen Metallen miteinander Die Erfindung beziehst sich auf ein Verfahren zum Verbinden von Teilen aus gleichen oder verschiedenen Metallen miteinander, z. B. von Rippen mit Rohren zu Rippenrohren für Wärmeaustauschzwecke, wobei die lose zusammengesetzten bzw. zusammengesteckten Metallteile zunächst durch Tauchen in ein Bad aus Metall mit verhältnismäßig niedrigem Schmelzpunkt, z. B. Zn oder Sn, miteinander verbunden werden.Method of joining parts of the same or different Metals to one another The invention relates to a method of joining of parts made of the same or different metals with one another, e.g. B. of ribs with tubes to finned tubes for heat exchange purposes, the loosely assembled or assembled metal parts first by immersion in a metal bath with a relatively low melting point, e.g. B. Zn or Sn, interconnected will.

Derartige an sich bekannte Verbindungen von Metallteilen miteinander genügen im allgemeinen den an sie gestellten mechanischen Belastungen. Sollen dagegen solche Metallteile, z. B. Rippenrohre, deren Rippen auf diese Weise mit den Rohren verbunden sind, für Wärmea,u:stauscher Verwendung finden, bei denen sie hohen Wärmebeanspruchungen ausgesetzt werden sollen, so ist auf Grund des niedrigen Schmelzpunktes des Verbindungsmetalls ein Ablösen der Rippen von den Rohren die Folge. Derartig aufgebaute Rippenrohre können daher nur in einem eng begrenzten niederen Temperaturbereich zur Anwendung kommen.Such connections, known per se, of metal parts with one another generally suffice for the mechanical loads placed on them. Should against it such metal parts, e.g. B. finned tubes whose fins in this way with the tubes are connected, for Wärmea, u: exchangers use where they are exposed to high heat loads should be exposed, it is due to the low melting point of the connecting metal the result is a detachment of the ribs from the tubes. Finned tubes constructed in this way can therefore only be used in a narrow, low temperature range come.

Die Erfindung besteht nun darin, daß der die Verbindung der Metallteile herstellende Metallüberzug aus Metallen niederen Schmelzpunktes durch Tauchen des Gegenstandes in ein Bad aus Metallen höheren Schmelzpunktes, z. B. Al oder Cu, in eine hitzebeständige Legierung umgewandelt wird.The invention consists in that the connection of the metal parts producing metal coating from metals with a low melting point by dipping the Object in a bath of metals with a higher melting point, e.g. B. Al or Cu, in a heat-resistant alloy is converted.

Diese erfindungsgemäße Maßnahme des Eintauchens des Gegenstandes in ein Bad aus Metallen höheren Schmelzpunktes und die dadurch hervorgerufene UmwandJung des Verbindungsmetal'les niederen Schmelzpunktes in eine Legierung mit höherer Hitzebeständigkeit hat zur Folge, daß bei derart behandelten Rippenrohren ein Ablösen der Rippen von den Rohren bei hoher Wärmebelastung nicht zu befürchten ist. Da außerdem eine einwandfreie metallische Verbindung zwischen den Rippen und den Rohren auch bei hohen Wärmebeanspruchungen erhalten bleibt, ist damit ein guter Wärmeübergang zwischen den wärm,eaustauschenden Mitteln gewährleistet.This measure according to the invention of immersing the object in a bath of metals with a higher melting point and the resulting transformation of the connecting metal with a lower melting point into an alloy with higher heat resistance has the consequence that in finned tubes treated in this way, the fins are detached from the pipes are not to be feared at high heat loads. Since also a flawless metallic connection between the ribs and the tubes even with high thermal loads is retained, there is thus a good heat transfer between the heat exchangers Funds guaranteed.
