Abstract

Guide channels (10) inside the end section (9) of the connector piece (3) branch off in a star shape from the inlet part (8) of the piece. The cooled pipes (4) are set in a base (6) and arranged to form a partial circuit, into which the guide channels lead. The connector piece has a cylindrical inlet part connected to the uncooled pipe (2), which widens out into an end section containing guide channels running coaxial to one of the cooled pipes and leading away from the inlet part.

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 connecting piece between an uncooled tube 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.There are connectors for heat exchangers known (DE-PS 39 10 630), in which the end of a hot, uncooled tube bifurcated outward and thermally insulated. This Connector diverts the hot gas into a single one outside z. B. by boiling water cooled tube. This Principle has been proven. However, in a sense, as disadvantageous to see that the cooled tube, which in the Diameter approximately equal to the uncooled tube, due its large diameter must be made relatively long. This is due to thermodynamic reasons, to the desired cooling of the hot gas to a certain 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 tube can be considerably shorter and thus the heat exchanger are made cheaper, if the hot medium from an uncooled tube to a plurality of cooled pipes of smaller diameter is distributed. Therefor Constructions are known in which a hot medium of an inlet by means of an inlet chamber to a plurality is distributed by cooled pipes, in a common Tube bottom are held. The disadvantage here, however Turbulence of the flowing medium when hitting the Tube bottom and possible tube soil 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, whose double tubes with one serving as a collector Oval tube are connected. On the gas inlet side of the Heat exchanger is provided an entry piece in which several each connected to a gas supply pipe Gas passages are formed. Every gas passage widens in the flow direction and distributes the supplied hot gas several cooled pipes. The disadvantages of this heat exchanger are the great longitudinal length and the fact that each cooled tube has its own jacket tube for receiving the Coolant requires. In addition, the entry piece is from complex and therefore 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-A-5 464 057.In another known double tube heat exchanger is a Connector used in the manner of a trouser pipe is formed and retains the cross section in two or three branch pipes branched. Each of these branch pipes is assigned to one of the double tubes. This double tube heat exchanger has basically the same disadvantages as the double-tube heat exchanger according to US Pat. No. 5,464,057.

In der US-A-5 816 322 ist ein Doppelrohr-Wärmetauscher beschrieben, bei dem die Doppelrohre auf einen Teilkreis angeordnet und mit einem ringförmigen Ovalrohrsammler verbunden sind. Die Doppelrohre stehen über ein Verbindungsstück mit einem Gaszuführungsrohr in Verbindung. Das verbindungsstück weist einen sich erweiternden Abschnitt auf, in dem Führungskanäle vorgesehen sind, die koaxial zu jeweils einem der Doppelrohre angeordnet sind.In US-A-5 816 322 is a double-tube heat exchanger described in which the double tubes on a pitch circle arranged and connected to an annular oval tube collector are. The double tubes are connected via a connector with a Gas supply pipe in connection. The connecting piece has a widening section in which guide channels are provided, which are coaxial with each one of the double tubes are arranged.

Aus der AT-B-373 385 ist ein Luft-Luft-Wärmetauscher bekannt, bei dem mehrere Wärmetauscherrohre von einem gemeinsamen Außenmantel umgeben sind. Die Wärmetauscher münden in einen sich konisch verengenden Verbindungsstutzen ein.From AT-B-373 385 an air-to-air heat exchanger is known, in which a plurality of heat exchanger tubes from a common Outer jacket are surrounded. The heat exchangers open into one conically narrowing connecting piece.

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 is based on the object, the generic Heat exchanger to make such that a hot medium of an uncooled tube by means of a connector relative simple and inexpensive design low-turbulence on a Majority of cooled pipes can be distributed Simultaneous compact space-saving design while avoiding a directly flowed tube bottom.
