Description

Die Erfindung betrifft einen Wärmetauscher mit einem Verbindungsstück zwischen einem ungekühlten Rohr und mehreren gekühlten Rohren gemäß dem Oberbegriff des Patentanspruches 1.The invention relates to a heat exchanger with a Connector between an uncooled pipe and several cooled pipes according to the preamble of claim 1.

Es sind Verbindungsstücke für Wärmetauscher bekannt (DE-PS 39 10 630), bei denen das Ende eines heißen, ungekühlten Rohres gabelförmig nach außen erweitert und wärmeisoliert ist. Dieses Verbindungsstück leitet das heiße Gas in ein einziges von außen z. B. durch siedendes Wasser gekühltes Rohr. Dieses Prinzip hat sich bewährt. Jedoch ist in gewisser Weise als nachteilig anzusehen, daß das gekühlte Rohr, welches im Durchmesser etwa dem ungekühlten Rohr entspricht, aufgrund seines großen Durchmessers relativ lang ausgeführt werden muß. Das ergibt sich aus thermodynamischen Gründen, um die gewünschte Abkühlung des heißen Gases auf eine bestimmte Temperatur zu erreichen.Connectors for heat exchangers are known (DE-PS 39 10 630) where the end of a hot, uncooled pipe is forked outward and thermally insulated. This Connector directs the hot gas into a single one outside z. B. tube cooled by boiling water. This Principle has proven itself. However, in some ways it is considered disadvantageous to consider that the cooled pipe, which in the Diameter corresponds approximately to the uncooled pipe, due to its large diameter must be made relatively long. This is due to thermodynamic reasons Desired cooling of the hot gas to a certain one To reach temperature.

Die Länge des gekühlten Rohres kann erheblich kürzer und damit der Wärmetauscher kostengünstiger ausgeführt werden, wenn das heiße Medium von einem ungekühlten Rohr auf eine Mehrzahl von gekühlten Rohren kleineren Durchmessers verteilt wird. Hierfür sind Konstruktionen bekannt, bei denen ein heißes Medium von einem Eintritt mittels einer Eintrittskammer auf eine Mehrzahl von gekühlten Rohren verteilt wird, die in einem gemeinsamen Rohrboden gehalten sind. Nachteilig hierbei sind jedoch Verwirbelungen des strömenden Mediums beim Auftreffen auf den Rohrboden und mögliche Rohrbodenerosionen.The length of the cooled pipe can be considerably shorter and therefore the heat exchanger can be run more cost-effectively if that hot medium from an uncooled pipe to a plurality of cooled pipes of smaller diameter is distributed. Therefor Constructions are known in which a hot medium from an entry to a plurality by means of an entry chamber of chilled pipes that are distributed in a common Tube sheet are held. However, this is disadvantageous Turbulence of the flowing medium when it hits the Tube sheet and possible tube sheet erosion.

Aus der US-PS 54 64 057 ist ein Doppelrohr-Wärmetauscher bekannt, dessen Doppelrohre mit einem als Sammler dienenden Ovalrohr verbunden sind. Auf der Gaseintrittsseite des Wärmetauschers ist ein Eintrittsstück vorgesehen, in dem mehrere jeweils mit einem Gaszuführungsrohr verbundene Gasdurchgänge gebildet sind. Jeder Gasdurchgang erweitert sich in Strömungsrichtung und verteilt das zugeführte heiße Gas auf mehrere gekühlte Rohre. Die Nachteile dieses Wärmetauschers sind die große Baulänge in Längsrichtung und der Umstand, daß jedes gekühlte Rohr ein eigenes Mantelrohr zur Aufnahme des Kühlmediums erfordert. Außerdem ist das Eintrittsstück von aufwendiger und dementsprechend teurer Bauart.From US-PS 54 64 057 is a double tube heat exchanger known, the double pipes with a serving as a collector Oval tube are connected. On the gas inlet side of the An inlet piece is provided in the heat exchanger several each connected to a gas supply pipe Gas passages are formed. Each passage of gas expands in the direction of flow and distributes the supplied hot gas several cooled pipes. The disadvantages of this heat exchanger are the long length and the fact that each cooled tube has its own jacket tube to accommodate the Coolant required. In addition, the entry piece is from complex and accordingly expensive design.

Bei einem anderen bekannten Doppelrohr-Wärmetauscher wird ein Verbindungsstück eingesetzt, das nach Art eines Hosenrohres ausgebildet ist und sich unter Beibehaltung des Querschnittes in zwei oder drei Zweigrohre verzweigt. Jedes dieser Zweigrohre ist einem der Doppelrohre zugeordnet. Dieser Doppelrohr-Wärmetauscher weist die grundsätzlich gleichen Nachteile auf wie der Doppelrohr-Wärmetauscher gemäß US-PS 54 64 057.In another known double tube heat exchanger, a Connection piece used, the manner of a downpipe is formed and while maintaining the cross section branched into two or three branch pipes. Any of these Branch pipes are assigned to one of the double pipes. This Double-tube heat exchangers have basically the same Disadvantages such as the double tube heat exchanger according to US-PS 54 64 057.

Der Erfindung liegt die Aufgabe zugrunde, den gattungsgemäßen Wärmetauscher derart zu gestalten, daß ein heißes Medium von einem ungekühlten Rohr mittels eines Verbindungsstückes relativ einfacher und kostengünstiger Bauart turbulenzarm auf eine Mehrzahl von gekühlten Rohren verteilt werden kann bei gleichzeitiger kompakter platzsparender Bauart unter Vermeidung eines direkt angeströmten Rohrbodens.The invention has for its object the generic To design heat exchangers so that a hot medium of an uncooled pipe using a connector relatively simple and inexpensive design with low turbulence a plurality of cooled pipes can be distributed at at the same time compact, space-saving design under Avoiding a tube sheet with direct flow.

Das gleiche gilt für die gekühlten Rohre, welche dadurch ebenfalls in einem gemeinsamen Außenmantel geführt werden können. Dies ermöglicht eine kostengünstige und platzsparende zylindrische Bauart des Wärmetauschers.Due to the arrangement of the guide channels and of the corresponding cooled pipes on the smallest possible enclosable area, it is possible for the guide channels a common preferably cylindrical shell to provide. The same applies to the cooled pipes, which thereby also performed in a common outer jacket can be. This enables an inexpensive and space-saving cylindrical design of the heat exchanger.
