Description

KAISERLICHESIMPERIAL

PATENTAMT.PATENT OFFICE.

Vorliegende Erfindung betrifft ein Heizoder Kühlrohr mit schraubenförmiger Außenfläche. Das Neuartige der Erfindung besteht darin, daß die Schraubengänge hohl ausgebildet sind und die Kühl- oder Heizflüssigkeit durch dieselben geleitet wird, zum Zweck, die direkten Ausstrahlungsflächen zu vergrößern gegenüber den bekannten Vorrichtungen mit aufgeschobenen oder angegossenenThe present invention relates to a heating or cooling pipe with a helical outer surface. The novelty of the invention is that the screw threads are hollow and the cooling or heating fluid is passed through them for the purpose of to enlarge the direct radiation areas compared to the known devices with pushed-on or cast-on

ίο Scheiben oder spiralförmig herumgewundenen Metallstreifen.ίο discs or spirally wound around Metal strips.

Wie aus der Zeichnung ersichtlich, besteht das Heiz- und Kühlrohr aus zwei ineinandergeschobenen Metallrohren, von denen das äußere einen oder mehrere spiralförmig eingewalzte oder direkt durch Guß hergestellte Gänge besitzt. Das innere Rohr besitzt die gewöhnliche Form und schließt sich den inneren Schraubengängen dicht an. Die Enden sind aber so abgedichtet, daß die Luft oder allgemein der die Wärme aufnehmende Stoff nur in das Innere des Rohres b eintreten kann. Das Heizmittel wird bei α zugeführt, kreist in den hohlen Schraubengängen und tritt am anderen Ende wieder aus.As can be seen from the drawing, the heating and cooling tube consists of two metal tubes pushed into one another, the outer one of which has one or more spirally rolled or cast-in turns. The inner tube has the usual shape and tightly joins the inner screw threads. The ends are sealed so that the air or generally the heat-absorbing substance can only enter the interior of the tube b . The heating medium is fed in at α , circles in the hollow screw threads and exits again at the other end.

Durch diese Anordnung wird eine größere Ausstrahlungsfläche erzielt, welche noch durch das innere Rohr bei den Spiralgängen erhöht wird.With this arrangement, a larger emission area is achieved, which is still due to the inner tube is increased in the spiral threads.
