Abstract

A heat exchanger comprises two cylinders one inside the other. The inner one is constricted at the ends where it connects with the flow of the one medium and the outer one is enlarged at its ends where it connects with the flow of the other medium. Both the channels so formed are provided with a helical baffle to direct the flow of the liquid passing through them. Connecting sleeves for the exchange medium enter the outer cylinder at both ends.

Wärmeaustauscher mit zwei einander mit Abstand umgebenden FührungsrohrenHeat exchanger with two guide tubes surrounding each other at a distance

Die Erfindung bezieht sich auf einen Wärmeaustauscher mit zwei einander mit Abstand umgebenden Führungsrohren, wobei das innere Führungsrohr von dem einen Medium und der Ringraum zwischen den beiden Führungs rohren von dem anderen Medium durchflossen ist. Derartige Wärmeaustauscher werden vorwiegend in Kälteanlagen für den Wärmeaustausch zwischen einem gasförmigen und einem flüssigen Medium benutzt. Dabei strömt meist das Gas durch das Innenrohr und die Flüssigkeit durch den Ringraum,The invention relates to a heat exchanger with two guide tubes surrounding one another at a distance, the inner guide tube from one medium and the annular space between the two guide tubes from the other medium is flowed through. Such heat exchangers are mainly used in refrigeration systems for heat exchange between a gaseous and a liquid medium used. The gas usually flows through the inner tube and the liquid the annulus,

Bei bekannten Wärmeaustauschern dieser Art sind für den Anschluß der beiden die Medien führenden Leitungen besondere Anschlußstücke vorgesehen. Meist sind die an jedem Ende vorgesehenen Anschlußstücke in einem einzigen Formteil vereinigt, der mit dem Innenrohr und dem Außenrohr verschweißt oder verlötetIn known heat exchangers of this type, special connection pieces are required for connecting the two lines carrying the media intended. Usually the connecting pieces provided at each end are combined in a single molded part, the welded or soldered to the inner tube and the outer tube

Der Erfindung liegt die Aufgabe zu Grunde, die kostspieligen Formstücke für den Leitungsanschluß zu vermeiden.The invention is based on the object, the expensive fittings for the line connection.

Diese Aufgabe wird gemäß der Erfindung dadurch gelöst, daß das innere Führungsrohr an seinen Enden für den Anschluß der einen Leitung auf einen kleineren Durchmesser eingezogen, hinter seinen Anschlußenden mit den dort auf einen kleineren Durchmesser eingezogenen Enden des äußeren Führungsrohres verschweißt oder verlötet ist und an den beiden Stirnseiten des äußeren Führungsrohres im Bereich einer Ausbeulung oder Auskümpelung seiner Wand Öffnungen vorgesehen sind, in die Anschlußstutzen für die zweite Leitung eingeschweißt oder eingelötet sindo This object is achieved according to the invention in that the inner guide tube is drawn in at its ends for the connection of one line to a smaller diameter, welded or soldered behind its connection ends to the ends of the outer guide tube drawn in there to a smaller diameter and to the openings are provided on both end faces of the outer guide tube in the area of a bulge or bulge in its wall, into which the connecting pieces for the second line are welded or soldered, or the like

Ein gemäß der Erfindung gestalteter Wärmeaustauscher ist in der Zeichnung im Längsschnitt· dargestellt.A heat exchanger designed according to the invention is shown in the drawing in longitudinal section.

Mit 1 ist das innere Führungsrohr und mit 2 das äußere Führungsrohr bezeichnet. Das innere Führungsrohr 1 hat auf einen kleineren Durchmesser eingezogene Enden 3 und 4, die Anschlußstutzen für die das eine Medium führende Leitung bilden · Das einen größeren Durchmesser aufweisende äußere Führungsrohr 2 ist hinter den eingezogenen Enden 3 und 4 des Innen rohres^ mit auf einen kleineren Durchmesser eingezogenen Enden 5 und 6 mit dem Mantel des Innenrohres verschweißt oder verlötet»1 is the inner guide tube and 2 is the outer guide tube designated. The inner guide tube 1 has ends 3 and 4 drawn in to a smaller diameter, the connecting pieces for which form the line leading one medium · The outer guide tube 2, which has a larger diameter, is behind the drawn-in ends 3 and 4 of the inner tube ^ with on one smaller diameter drawn-in ends 5 and 6 welded or soldered to the jacket of the inner tube »

609820/0623609820/0623

In jeder der auf den kleineren Durchmesser überleitenden ringförmigen Stirnseiten 7 und 8 des äußeren Führungsrohres 2 ist eine Ausbeulung 9 bzw«, 10 mit einer Öffnung 11 bzw. 12 vorgesehen, in die Anschlußstutzen 13 und 14 für die das zweite Medium führende Leitung eingeschweißt oder eingelötet sind.In each of the ring-shaped ones transitioning to the smaller diameter End faces 7 and 8 of the outer guide tube 2 are provided with a bulge 9 or 10 with an opening 11 or 12, respectively. are welded or soldered into the connecting pieces 13 and 14 for the line carrying the second medium.

Beim Ausführungsbeispiel ist in den Ringraum 15 zwischen den beiden Führungsrohren 1 und 2 eine Drahtschraube 16 eingelegt, die eine Drallströmung bewirkt. Auch in das Innenrohr ist eine im ganzen mit 17 bezeichnete Drallvorrichtung eingesetzt,,In the embodiment is in the annular space 15 between a wire screw 16 inserted in both guide tubes 1 and 2, which causes a swirl flow. Also in the inner tube, a swirl device designated as a whole by 17 is inserted,
