KAISERLICHESIMPERIAL
PATENTAMT.PATENT OFFICE.
Durch das Haupt-Patent ist ein Rippenrohr für Heiz- oder. Kühlzwecke bekannt geworden, bei welchem die sonst üblichen angegossenen Rippen durch eine fortlaufende geschmiedete oder gewalzte Schraube α ersetzt sind, die auf ein glattes, von der Heiz- oder Kühlflüssigkeit durchströmtes Rohr b aufgezogen wird. Dieses Rohr, das cylindrischen oder flachrunden Querschnitt haben kann, wird zur Verwendung als Heizkörper schlangen- oder schraubenförmig gebogen (Fig. 1 und 2), wobei die fortlaufende Schraubenrippe sich allen Formen des Rohres b anschmiegt.The main patent is a finned tube for heating or. Cooling purposes have become known in which the otherwise customary cast-on ribs are replaced by a continuous forged or rolled screw α , which is pulled onto a smooth tube b through which the heating or cooling liquid flows. This tube, which can have a cylindrical or flat-round cross-section, is bent in a serpentine or helical shape for use as a radiator (FIGS. 1 and 2), the continuous helical rib clinging to all shapes of the tube b.
Im Gebrauch haben diese Heizkörper jedoch den Nachtheil gezeigt, dafs der Wärmedurchgang an der Stelle, wo die Rippe an das Rohr anschliefst, zuweilen erschwert ist. Infolge dessen hat die Rippe nicht die volle Wirksamkeit.In use, however, these radiators have shown the disadvantage that the heat transfer is sometimes difficult at the point where the rib joins the tube. As a result the rib does not have the full effectiveness of this.
Gemäfs vorliegender Erfindung wird nun dieser Nachtheil dadurch beseitigt, dafs die Berührungsfläche zwischen Rippe und Rohr vergröfsert und eine feste Verbindung zwischen diesen Theilen geschlossen wird.According to the present invention, this disadvantage is eliminated by the fact that the Increased contact area between rib and tube and a firm connection between these parts is closed.
Fig. 3 zeigt mehrere - Ausführungsformen dieser Verbindung.Fig. 3 shows several embodiments of this connection.
Bei der ersten derselben ist in das Rohr eine schraubenförmige Rille c eingedrückt, in welche die Rippe hineingeschraubt werden kann. Die Kante der Rippe ist entsprechend der Rille gerundet.In the first of these, a helical groove c is pressed into the tube, into which the rib can be screwed. The edge of the rib is rounded to match the groove.
Bei der zweiten Ausführungsform ist- das Rohr aufgeweitet, und zwar entweder im Ganzen, oder so, dafs neben der Spiralrippe zwei Wulste d entstehen, die die Rippe festhalten und die Berührungsfläche verbreitern.In the second embodiment, the tube is widened, either in its entirety, or in such a way that, next to the spiral rib, there are two bulges d which hold the rib and widen the contact surface.
Die dritte Ausführungsform unterscheidet sich von der ersten dadurch, dafs die Kante der Rippe zwar verbreitert, aber nicht abgerundet ist. Bei der vierten Form ist die Schraubennuth eingeschnitten und greift über die verbreiterte Kante der Rippe, wodurch diese sehr fest gehalten wird. Man kann auch die Innenkante der Rippe mit einer Umbördelung e versehen, wobei ebenfalls eine genügende Berührungsfläche erhalten wird.The third embodiment differs from the first in that the edge of the rib is widened but not rounded. In the fourth form, the screw groove is cut and engages over the widened edge of the rib, which holds it very firmly. The inner edge of the rib can also be provided with a flange e , with a sufficient contact surface also being obtained.
Um die Verbindung zu einer innigen zu machen, kann man die Schraubenrippe in heifsem Zustande auf das kalte Rohr aufziehen oder auch das Rohr nach Aufbringen der Rippe weiten.To make the connection intimate, the screw rib can be turned into In the hot condition, pull it onto the cold pipe or the pipe after the rib has been applied widen.
