Description
Radiatorglied aus zwei ineinanderliegenden Röhren. Gegenstand der Erfindung ist ein Radiatorglied aus zwei ineinanderliegenden Rohren. Bei ovaler Rohrform liegt die Gefahr der Formveränderung durch Innendruck vor, der bisher durch entsprechende Wandungsstärke oder durch Verankerung begegnet werden mußte. Durch die Erfindung soll ermöglicht werden, solche Radiatoren auch mit schwachen Wandstärken ohne besondere Verankerung auszuführen. Erreicht wird das dadurch, daß die Rohre längs ihrer spitzen Seiten miteinander verbunden werden, so daß sie sich gegenseitig versteifen.Radiator element made up of two tubes one inside the other. Subject of Invention is a radiator element made of two tubes one inside the other. With oval Pipe shape there is a risk of shape change due to internal pressure, which was previously caused by corresponding wall thickness or had to be countered by anchoring. By the invention should be made possible, such radiators with weak wall thicknesses to be carried out without special anchoring. This is achieved by the pipes be connected to one another along their pointed sides, so that they are mutually exclusive stiffen.
Die Rohre a und b werden gegossen oder aus Blech, vorzugsweise aus Aluminiumblech, hergestellt. Ihr Querschnitt ist elliptisch. Bei c berühren sich die beiden Rohre, wodurch zwei getrennte Kammern d für das Heizmittel erzielt werden. Längs der Mantellinien c werden die Rohre miteinander verbunden.The tubes a and b are cast or made of sheet metal, preferably from Aluminum sheet. Their cross-section is elliptical. At c touch the two tubes, whereby two separate chambers d are obtained for the heating medium. The tubes are connected to one another along the surface lines c.
Die Verbindung bei c erfolgt zweckmäßig durch Löten oder Schweißen.The connection at c is expediently made by soldering or welding.
Wenn das Glied Wasser- oder Dampfdruck in den beiden Kammern d ausgesetzt wird, sucht sich das äußere Rohr a in Richtung c-c zu verkürzen, daß innere Rohr b dagegen zu verlängern. Da sich aber die beiden elliptischen Rohre nicht unabhängig voneinander bewegen können, hindern sie sich gegenseitig an der Formänderung. Um d@i:e beiden Kammern d in Verbindung miteinander zu bringen, sind an den flachen Seiten der Rohre, oben und unten, in Flucht mit den Ein- und Auslaufstutzen e Verbindungsstücke f eingesetzt.When the member is exposed to water or steam pressure in the two chambers d, the outer tube a seeks to shorten in the direction cc, while the inner tube b tries to lengthen it. However, since the two elliptical tubes cannot move independently of one another, they prevent one another from changing shape. In order to bring d @ i: e two chambers d into connection with one another, connecting pieces f are inserted on the flat sides of the pipes, above and below, in alignment with the inlet and outlet nozzles e.
Der Zwischenraum g zwischen den beiden Kammern d dient in bekannter Weise dem Luftumlauf.The space g between the two chambers d is used in a known manner Way the air circulation.
