Es ist bei Rippenrohren bekannt, an Stelle der Einzelrippen eine' schraubenförmig fortlaufende Rippe zu verwenden. Diese Rippe wurde mit dem endgültigen Abstand der einzelnen Windungen fertiggestellt und dann auf das Rohr geschoben. Zwecks dauerhafter, inniger Verbindung zwischen der Schraube und dem Rohr mußte entweder das ganze Rohr verzinkt oder die Schraube an das Rohr'It is known in the case of finned tubes, instead of the individual ribs, a 'helically continuous' Use rib. This rib was made with the final spacing of each Turns completed and then pushed onto the pipe. For the purpose of a permanent, intimate connection between the screw and the pipe had either the whole pipe galvanized or the screw on the pipe '
ίο angelötet werden, wenn man von besonderen maschinellen Einrichtungen und umständlichen Verfahren zur Herstellung einer .allseitigen Verbindung zwischen Schraube und dem Rohr absah.ίο be soldered on, if one of special mechanical equipment and cumbersome process for the production of a .all-sided The connection between the screw and the pipe was disregarded.
Eine innige, dauerhafte Verbindung der Schraube mit dem Rohr ist aber notwendig, wenn die Schraube in. allen Teilen mit zur Wärme- oder Kälteübertragung beitragen soll.An intimate, permanent connection between the screw and the pipe is necessary, when the screw contributes to the transfer of heat or cold in all parts target.
so Durch vorliegende Erfindung werden die Schwierigkeiten behoben und ein Verzinken des fertigen Rippenrohres oder ein Anlöten der Schraube an das Rohr überflüssig. Die Schraube wird, wie Fig. 2 zeigt, mit. aneinander anliegenden Gängen fertiggestellt und erhält eine.Bohrung, die das Aufschieben der Schraube auf das Rohr eben ermöglicht.so the present invention overcomes the difficulties and galvanizing the finished finned tube or soldering the screw to the tube is superfluous. the Screw is, as Fig. 2 shows, with. Completed and adjoining corridors receives a hole that enables the screw to be pushed onto the pipe.
In rotwarmem Zustande wird diese Schraube, wie Fig. 1 zeigt, auf das Rohr geschoben, der Anfang derselben mit dem Rohr fest verbunden und mit besonderer Vorrichtung auf den jeweilig erforderlichen Gangabstand ausgezogen. Durch das Ausziehen der Schraube wird die Bohrung kleiner, so daß sich die einzelnen Gänge fest an die Rohroberfläche anlegen.In red-warm condition, this screw is pushed onto the pipe, as shown in Fig. 1, the beginning of the same firmly connected to the pipe and with a special device to the respective required aisle spacing moved out. By pulling out the screw, the hole becomes smaller, so that the individual threads are firmly attached to the pipe surface invest.
