Description

Glattrohrbündelwärmeaustauscher.Smooth tube bundle heat exchanger.

Beschreibung: Die Erfindung betrifft einen Glattrohrwärmeaustauscher mit sich untereinander berührenden Innenrohren, die im Umfangsrohr so enge eingebracht sind, daß sie auch diese berührten.Description: The invention relates to a smooth tube heat exchanger with inner tubes in contact with one another, which are inserted so tightly in the circumferential tube are that they touched these too.

Abb.(3) zeigt einen Wänneaustauscher dieses Prinzies.Fig. (3) shows a heat exchanger of this principle.

Ein solcher Wärmeaustauscher mit seinen Vorteilen wurde erstmals bekannt durch die Patentschrift 247 581.Such a heat exchanger with its advantages became known for the first time by patent specification 247,581.

Ki 17 F 5.01 v. 31.5.1912.Ki 17 F 5.01 BC May 31, 1912.

Die Schwierigkeit bei dieser Art Wärmeaustauscher ist das Beschicken der Hohlräume zwischen den Rohren mit deni Wärmeträger.The difficulty with this type of heat exchanger is loading the cavities between the pipes with the heat transfer medium.

Die Lösung dieses Problems zeigen die folgenden Patentschriften: 1.) Patent 612 926 KL. 17 F. 501 2.) Patent 831 00 KL. 17 F. 502 B ide Lösungen sind fertigungstechnisch und im Hinblick auf Nosten aufwendig. Sie erfordern ein kompliziertes Außenrohr, schwieriges und unterschiedliches Verformen der Innenrohre und eine zusätzliche Dichtplatte zur Endabdichtung der Innenrohre.The solution to this problem is shown in the following patent specifications: 1.) Patent 612 926 KL. 17 F. 501 2.) Patent 831 00 KL. 17 F. 502 B ide solutions are Complex in terms of production technology and with regard to costs. They require a complicated one Outer pipe, difficult and different deformation of the inner pipes and an additional one Sealing plate for the end sealing of the inner pipes.

Die vorliegende Erfindung hat es sich zur Aufgabe gesetzt diese Nachteile zu vermeiden.The present invention addresses these disadvantages to avoid.

Die Erfindung besteht darin, daß die Innenrohre (1) dicht neben den beiden Enden Verengungen (2) aufweisen, die ein Beschicken der hohlräume (3) zwischen den Rohren ermöglichen, ohne daß diese Rohre aus ihrer achsialen Lage gebracht werden müssen. Dies ermöglicht eine leichte Montage ohne Verformung der Innenrohre.The invention consists in that the inner tubes (1) close to the both ends have constrictions (2), which feed the cavities (3) between enable the pipes without these pipes being brought out of their axial position have to. This enables easy assembly without deforming the inner tubes.

Die Verengungen der Innenrohre können z. B. sehr leicht eingewalzt werden. Dies kann vorzugs<eise in Form von schmalen Nuten wie Abb. (l) zeigt geschehen.The constrictions of the inner tubes can, for. B. rolled in very easily will. This can preferably be done in the form of narrow grooves as shown in Fig. (1) happen.

Dadurch entsteht eine Art Wellrohr, das geeignet ist Längenänderungen vornehmlich aus Wärmedehnung nut zunehmen.This creates a kind of corrugated pipe that is suitable for changes in length primarily due to thermal expansion.

Eine direkt am Ende des Innerohres eingebrachte Verengung (14) ermöglicht eine leichte Abdichtung durch Schlieißen, Löten oder Kleben.A constriction (14) introduced directly at the end of the inner ear is made possible a light seal by closing, soldering or gluing.

Die Verengung kann auch dadurch entstehen, daß das gesamte Ende der Innerohre nut mehrere Zentimeter Länge dünner gewalzt wird, oder wie in Abb. (2) eargestellt dünnere Rohre eingesetzt werden. Auch hier bietet sich die gute Abdichtmöglichkeit am Innenrohrende (all) an. Allerdings ist die Kompensattion der Längenänderung nicht gegeben.The narrowing can also be caused by the entire end of the Inner tubes are rolled thinner by several centimeters, or as shown in Fig. (2) thinner tubes can be used. Here, too, there is a good sealing option at the inner pipe end (all). However, the compensation for the change in length is not given.

Patentansprüche: 1.)) Glattrohrwärmeaustauscher mit sich untereinander den den Innenumfang des Außenrohres berührenden Innenrohren dadurch gekennzeichnet, daß die Innen -rohre nahe der beiden Enden Verengungen aufweisen, durch die die Hohlräume zwischen den Rohren mit dem Wärmeträger beschickt werden können.Claims: 1.)) Smooth tube heat exchangers with each other the inner tubes touching the inner circumference of the outer tube characterized by: that the inner tubes have constrictions near the two ends through which the Cavities between the pipes can be charged with the heat transfer medium.

2.) Glattrohrbärmeaustauscher nach Anspruch (1) dadurch gekennzeichnet daß die Verengungen der Innenrohre so ausgebildet sind, daß sie Längen -änderungen kompensieren können.2.) smooth tube heat exchanger according to claim (1) characterized that the constrictions of the inner tubes are designed so that they change in length can compensate.

3.) Glattrohrwärmeaustauscher nach Anspruch (1) dadurch gekennzeichnet daß das Ende der Innen -rohre ebenfalls verjüngt ist, um eine bessere Abdichtung durch Löten, Schweißen oder Kleben zu ermöglichen.3.) smooth tube heat exchanger according to claim (1) characterized that the end of the inner tubes is also tapered for a better seal by soldering, welding or gluing.

Claims (1)

4.) Glattrohrwärmeaustauscher nach Anspruch (1) dadurch gekennzeichnet daß die Verengung der Innerohre durch Einsetzen eines um die Wandstärke dünneren Rohres Abb. (2) erreicht wird.4.) smooth tube heat exchanger according to claim (1) characterized that the narrowing of the inner tubes by inserting a thinner by the wall thickness Rohres Fig. (2) is reached.
