Description

Die Erfindung betrifft einen Mehrwege-Wärmeaustauscher mit einem Rohrkörper sowie einer mit dem Rohrboden des Rohrkörpers verbundenen Haube, in der mindestens ein Steg zum Führen der in die Haube geleiteten Flüssigkeit angeordnet ist, wobei der Steg mit der Haube verbunden ist. Ein derartiger Mehrwege-Wärmeaustauscher ist bereits zum Beispiel aus der FR-A-2 476 826 bekannt.The invention relates to a multi-way heat exchanger with a tubular body and a hood connected to the tube sheet of the tube body, in which arranged at least one web for guiding the liquid passed into the hood is, wherein the web is connected to the hood. Such a multi-way heat exchanger is already for example known from FR-A-2 476 826.

Derartige Mehrwege-Wärmeaustauscher werden in der chemischen Industrie eingesetzt. Bei einem 2-Wege-Wärmeaustauscher trennt ein Steg die in die Haube geleiteten Flüssigkeit von dem aus der Haube geleiteten Flüssigkeit. Durch den Einbau von mehreren Stegen in die Haube eines 4- oder 6-Wege-Wärmeaustauschers wird der Flüssigkeitsstrom mehrfach in der Haube umgelenkt und gezwungen, den Wärmeaustauscher mehrfach zu passieren. Dadurch werden hohe Strömungsgeschwindigkeiten in den Rohren erreicht, und man erhält einen guten Wärmeübergang.Such multi-way heat exchangers are used in the chemical industry used. With a 2-way heat exchanger, a web separates them into the hood conducted liquid from the liquid discharged from the hood. By the Installation of several webs in the hood of a 4- or 6-way heat exchanger the liquid flow is deflected several times in the hood and forced to pass through the heat exchanger multiple times. This will reached high flow velocities in the pipes, and you get one good heat transfer.

Für den Einsatz bei in reinster Form vorliegenden Flüssigkeiten, insbesondere den Einsatz in Reinstwassersystemen (WFI = Water for Injection) können diese Konstruktionen nicht eingesetzt werden, da man für die Abdichtung der Stege Dichtungen benötigt, die durch Spaltenbildung die Gefahr der Bakterienanlagerung und Kontamination bergen. Aus diesem Grunde verwendete man bisher Wärmeaustauscher, mit nur einem Durchgang und doppelten Rohrböden. Die Strömungsgeschwindigkeiten in den Rohren solcher Wärmeaustauscher sind entsprechend niedrig; man erhält schlechte Wärmeübergangszahlen. Die Folge ist, daß diese Wärmeaustauscher steriltechnisch zwar einwandfrei sind, jedoch eine große Baulänge benötigen, um die Wärme abzuführen. Mehrere Meter Baulänge sind keine Seltenheit.For use with liquids in their purest form, especially the These can be used in ultrapure water systems (WFI = Water for Injection) Constructions can not be used as one for sealing the webs Seals needed, the risk of bacterial accumulation due to crevices and contamination. For this reason, one used so far Heat exchanger, with only one passage and double tube plates. The Flow velocities in the pipes of such heat exchangers are correspondingly low; one gets bad heat transfer numbers. The result is, that these heat exchangers are technically flawless, but one require a large length to dissipate the heat. Length of several meters are not uncommon.

Vor diesem Hintergrund ist es Aufgabe der vorliegenden Erfindung, einen Mehrwege-Wärmeaustauscher der eingangs genannten Art so weiter zu bilden, daß er für die Kühlung von in reinstem Zustand vorliegender Flüssigkeit, insbesondere Reinstwasser, verwendbar ist.Against this background, it is an object of the present invention to provide a multi-way heat exchanger of the type mentioned so far that he for the Cooling liquid in its purest state, in particular Ultrapure water that can be used.

Diese Aufgabe wird bei einem Mehrwege-Wärmeaustauscher der eingangs genannten Art dadurch gelöst, daß zwischen dem Steg und dem Rohrboden ein Spalt gebildet istThis task is the beginning of a multi-way heat exchanger mentioned type solved in that between the web and the tube sheet Gap is formed

Erfindungsgemäß unterteilt der Steg damit die Haube nicht in vollständig separierte Kammern, sondern es wird der Steg in seiner Länge so gefertigt, daß ein Abstand zwischen Steg und Rohrboden verbleibt. Dadurch kommt es zu einem Leckstrom durch den Spalt, der zum Freispülen dient. Der Leckstrom führt allerdings zu wärmetechnischen Verlusten, da er nicht den Wärmeaustauscher durchströmt und somit keiner Kühlung unterliegt. Es kommt zu einer Mischtemperatur zwischen dem Leckstrom und dem gekühlten, den Wärmeaustauscher verlassenden Strom. Trotz dieser Verluste ist der erfindungsgemäße Vorteil eines kompakten, kurzen, steril arbeitenden Wärmeaustauschers erheblich, da er GMP-konform istAccording to the invention, the web therefore does not subdivide the hood into completely separated ones Chambers, but it is the length of the web made so that a distance remains between the web and the tube sheet. This leads to a leakage current through the gap that is used for flushing. However, the leakage current leads to thermal losses since it does not flow through the heat exchanger and is therefore not subject to cooling. There is a mixing temperature between the Leakage current and the cooled current leaving the heat exchanger. Despite this loss is the advantage of a compact, short, sterile according to the invention working heat exchanger considerably, since it is GMP-compliant

Die Breite des Spaltes ist dahingehend zu optimieren, daß im Betrieb des Wärmeaustauschers ein ausreichender Leckstrom durch den Spalt fließt, um diesen frei zu spülen. In aller Regel reicht es aus, diesen Spalt kleiner als 1 mm zu wählen.The width of the gap is to be optimized so that in the operation of the A sufficient leakage current flows through the gap to the heat exchanger rinse freely. As a rule, it is sufficient to choose this gap smaller than 1 mm.

Vorzugsweise ist der Steg im Bereich des Rohrbodens angespitzt. Durch diese besonders strömungsgünstig gestaltete Form kann es im Bereich des dem Rohrboden zugewandten Stegendes nicht zu Anlagerungen kommen. The web is preferably pointed in the area of the tube sheet. Through this particularly aerodynamically designed shape it can in the area of the The web end facing the tube sheet does not accumulate.

In Abhängigkeit von der Art der verwendeten Mehrwege-Wärmeaustauscher sind mehrere Stege vorgesehen. Ein 4-Wege-Wärmeaustauscher weist beispielsweise zwei Stege auf. Diese sind insbesondere T-förmig angeordnet, so daß die Haube in drei Kammern unterteilt ist. Bei einem 6-Wege-Wärmeaustauscher wären dann vier Kammern vorzusehen. Die Stege sind zweckmäßig in einem Winkel von 90° zueinander angeordnet.Depending on the type of multi-way heat exchanger used several bridges are provided. For example, a 4-way heat exchanger two bridges. These are particularly T-shaped, so that the hood in is divided into three chambers. With a 6-way heat exchanger there would be four To provide chambers. The webs are expedient at an angle of 90 ° arranged to each other.

Die Figuren 1 und 2 zeigen den Flüssigkeitseintritts- und Austrittsbereich des 2-Wege-Wärmeaustauschers 1. Dessen Rohrkörper 2 weist einen Rohrboden 3 und sechzehn Rohre 4 auf, die in entsprechenden Löchern des Rohrbodens 3 abgedichtet gehalten sind. Den Rohrbereich des Rohrkörpers 2 deckt eine mit dem Rohrboden 3 verbundene Haube 5 ab, die mit einem Eintrittsstutzen 6 sowie einem Austrittsstutzen 7 für die im Wärmeaustauscher 1 zu kühlende Flüssigkeit, beispielsweise Reinstwasser, versehen ist. Die Strömungsrichtung der zu kühlenden Flüssigkeit ist in Figur 1 mittels der dick dargestellten Pfeile verdeutlicht. Abgesehen von den beiden Stutzen 6 und 7 ist die Haube rotationssymmetrisch ausgebildet. Im Bereich der Symmetrieebene 8 der Haube 5 ist mit dieser, somit deren Deckfläche 9 und deren Seitenfläche 10, ein dünnwandiger Steg 11 verbunden, der in Abstand zum Rohrboden 3 endet. Wie insbesondere der Darstellung der Figur 3 zu entnehmen ist, ist zwischen dem angespitzten Ende 12 des Steges und dem Rohrboden 3 ein Spalt 13 gebildet, der beispielsweise eine Stärke von 0,2 mm aufweist. Die zu kühlende Flüssigkeit strömt damit nicht nur durch die Rohre 4 des Wärmeaustauschers 1, sondern es gelangt, wie in Figur 3 durch den dick dargestellten Pfeil veranschaulicht, ein Leckstrom unmittelbar von der Eintrittskammer 14 der Haube 5 zu deren Austrittskammer 15.Figures 1 and 2 show the liquid inlet and outlet area of the 2-way heat exchanger 1. Its tubular body 2 has a tube sheet 3 and sixteen tubes 4 on the corresponding holes in the tube sheet 3 are kept sealed. The tube area of the tube body 2 covers one with the Tube bottom 3 connected hood 5, which with an inlet nozzle 6 and a Outlet connector 7 for the liquid to be cooled in the heat exchanger 1, for example, ultrapure water is provided. The flow direction of the to be cooled Liquid is illustrated in FIG. 1 by means of the arrows shown in bold. apart of the two nozzles 6 and 7, the hood is rotationally symmetrical. in the Area of the plane of symmetry 8 of the hood 5 is with the latter, and hence its top surface 9 and the side surface 10, a thin-walled web 11 connected, which is at a distance to the tube sheet 3 ends. As in particular the illustration in FIG. 3 remove is between the pointed end 12 of the web and the Pipe base 3 formed a gap 13 which has a thickness of 0.2 mm, for example. The liquid to be cooled thus flows not only through the tubes 4 of the Heat exchanger 1, but it passes, as in Figure 3 through the thick illustrated arrow illustrates a leakage current immediately from the Entry chamber 14 of hood 5 to its exit chamber 15.

Figur 4 zeigt die Ausbildung der Haube 5 bei einem 4-Wege-Wärmeaustauscher. Mit der Ausführungsform nach den Figuren 1 bis 3 in ihrer Funktion übereinstimmende Bauteile sind dort mit denselben Bezugsziffern bezeichnet. Bei der Ausführungsform nach Figur 4 sind zwei Stege 11 bzw. Stegbereiche vorgesehen, die in Art eines T angeordnet sind, wobei der eine Steg 11 eine Länge aufweist, die dem Durchmesser der Haube 5 entspricht, während die Länge des anderen Steges 11 dem Radius der Haube 5 entspricht. Bei entsprechender Änderung der Anordnung von Eintrittsstutzen und Austrittsstutzen, die den Kammern 14 und 15 zugeordnet sind, tritt die zu kühlende Flüssigkeit in die Eintrittskammer 14 ein, die im Bereich des ersten Viertels der Haube 5 angeordnet ist Sie strömt, abgesehen vom Leckstrom, durch die dieser Kammer 14 zugeordneten Rohre 4 in den Wärmeaustauscher 1 und verläßt den Rohrkörper 2 im Bereich des zweiten Viertels der Haube, von dort wird die Flüssigkeit in der Kammer 16 zu den im Bereich des dritten Viertels der Haube 5 angeordneten Rohren 4 umgelenkt. Sie tritt in die Rohre 4 ein und verläßt diese im Bereich der Austrittskammer 15, die dem viertel Viertel der Haube 5 zugeordnet ist. Im Bereich der T-förmigen Stege 11, die im Sinne der Darstellung der Figur 3 einen Spalt zum Rohrboden 3 bilden, entsteht der vorstehend beschriebene Leckstrom.Figure 4 shows the design of the hood 5 in a 4-way heat exchanger. With the embodiment of Figures 1 to 3 in their function matching Components are identified with the same reference numbers. In the embodiment 4 two webs 11 or web areas are provided, which in the manner of a T are arranged, the one web 11 having a length which corresponds to the diameter the hood 5 corresponds, while the length of the other web 11 corresponds to the radius of the Hood 5 corresponds. If the arrangement of Inlet connection and outlet connection, which are assigned to the chambers 14 and 15, the liquid to be cooled enters the inlet chamber 14, which is in the region of the arranged in the first quarter of the hood 5, apart from the leakage current, through the pipes 4 assigned to this chamber 14 into the heat exchanger 1 and leaves the tubular body 2 in the area of the second quarter of the hood, from there the liquid in the chamber 16 to that in the region of the third quarter of the hood 5 arranged tubes 4 deflected. It enters the tubes 4 and leaves them in Area of the outlet chamber 15, which is assigned to the quarter of the hood 5. In the area of the T-shaped webs 11, which in the sense of the illustration in FIG Form gap to the tube sheet 3, the leakage current described above arises.
