Description

Die Erfindung betrifft einen Plattenwärmetauscher gemäß dem Oberbegriff des Patentanspruchs 1.The invention relates to a plate heat exchanger according to the preamble of patent claim 1.

Der Aufbau eines Plattenwärmetauschers ist aus "The Standards of the Brazed Aluminium Plate-Fin Heat Exchanger Manufacturers' Association, ALPEMA", Second Edition, 2000 bekannt.The design of a plate heat exchanger is known from The Standards of the Brazed Aluminum Plate-Fin Heat Exchanger Manufacturers' Association, ALPEMA, Second Edition, 2000.

Der Wärmetauscherblock eines Plattenwärmetauschers besteht aus mehreren Lagen von Wärmeaustauschpassagen, die jeweils durch Trennbleche gegeneinander abgegrenzt sind. Abschlussleisten sowie Deckbleche bilden den äußeren Rahmen des Wärmetauscherblocks. Innerhalb einer Lage können weitere Trennleisten vorgesehen sein, die Wärmeaustauschpassagen für unterschiedliche Stoffströme voneinander trennen.The heat exchanger block of a plate heat exchanger consists of several layers of heat exchange passages, which are each delimited by separating plates against each other. End strips and cover plates form the outer frame of the heat exchanger block. Within a layer, further separating strips can be provided which separate heat exchange passages for different material flows from one another.

Der zunächst aus losen Bauteilen bestehende Wärmetauscherblock wird dann in einem Lötofen verlötet, so dass alle Bauteile miteinander dicht verbunden sind. Anschließend werden über den Ein- und Austrittsöffnungen der Wärmeaustauschpassagen Header aufgeschweißt, die mit einem Fluidanschluss versehen sind. Als Header werden üblicherweise halbzylindrische Schalen eingesetzt, können aber auch andere Formen aufweisen. Die Wände des Headers bilden mit der entsprechenden Seite des Blocks in der Regel einen Außenwinkel von 90° (siehe zum Beispiel " The Standards of the Brazed Aluminium Plate-Fin Heat Exchanger Manufacturers' Association, ALPEMA", Second Edition, 2000, Figur 1-5 ). Ein "Fluidanschluss" dient zur Zu- oder Abfuhr von Fluid in den oder aus dem Header. Er wird in der Regel durch einen Rohrstutzen gebildet, der in dem Halbzylindermantel des Headers gegenüber den Ein- bzw. Austrittsöffnungen angeordnet sind; an diese Rohrstutzen werden die Rohrleitungen für die zu- und abzuführenden Fluidströme angeschlossen. Alternativ kann der Fluidanschluss oder die im Wesentlichen senkrecht zu der Seite des Wärmetauscherblocks angeordnet sein, das Anschlussrohr setzt dann zum Beispiel den Header über den Rand des Blocks hinaus fort (siehe EP 1452817 A1 = US 2005006076 A1 ) über der sich der Header erstreckt.The initially made of loose components heat exchanger block is then soldered in a brazing furnace, so that all components are sealed together. Subsequently, headers are welded over the inlet and outlet openings of the heat exchange passages, which are provided with a fluid connection. As headers are usually used semi-cylindrical shells, but may also have other shapes. The walls of the header usually form an outside angle of 90 ° with the corresponding side of the block (see for example " The Standards of the Brazed Aluminum Plate-Fin Heat Exchanger Manufacturers' Association, ALPEMA, Second Edition, 2000, Figure 1-5 ). A "fluid port" serves to supply or discharge fluid into or out of the header. It is usually formed by a pipe socket, which are arranged in the half-cylinder jacket of the header opposite the inlet and outlet openings; At these pipe sockets, the pipes for the incoming and outgoing fluid flows are connected. Alternatively, the fluid port or the one substantially perpendicular to the side of the heat exchanger block may be arranged, for example, the connection tube then continues the header beyond the edge of the block (see FIG EP 1452817 A1 = US 2005006076 A1 ) over which the header extends.

Durch geeignete Anordnung von Trennleisten können Plattenwärmetauscher für den gleichzeitigen Wärmeaustausch von vielen Fluidströmen eingesetzt werden. Für jeden der Fluidströme sind dann entsprechende Header über den jeweiligen Ein- und Austrittsöffnungen der Wärmeaustauschpassagen anzubringen und mit Rohrleitungen zu versehen (siehe zum Beispiel " The Standards of the Brazed Aluminium Plate-Fin Heat Exchanger Manufacturers' Association, ALPEMA", Second Edition, 2000, Figur 1-1 ).By means of a suitable arrangement of separating strips, plate heat exchangers can be used for the simultaneous heat exchange of many fluid streams. For each of the fluid streams, appropriate headers are then to be attached above the respective inlet and outlet openings of the heat exchange passages and provided with pipelines (see, for example, "US Pat. The Standards of the Brazed Aluminum Plate-Fin Heat Exchanger Manufacturers' Association, ALPEMA, Second Edition, 2000, Figure 1-1 ).

Der Begriff "Seite" eines Wärmetauscherblocks ist hier geometrisch zu verstehen, das heißt es handelt sich um eine ebene Oberfläche des Wärmetauscherblocks, der in der Regel quaderförmig ausgebildet ist; die "Seite" weist daher in der Regel Rechteckform auf.The term "side" of a heat exchanger block is to be understood geometrically, that is, it is a flat surface of the heat exchanger block, which is generally cuboid-shaped; the "page" therefore generally has a rectangular shape.

Häufig treten in derartigen Headern relativ hohe Strömungsgeschwindigkeiten auf und bewirken einen hohen Druckverlust und/oder eine Fehlverteilung des Fluids auf die einzelnen Passagen.Frequently occur in such headers relatively high flow velocities and cause a high pressure drop and / or a misallocation of the fluid to the individual passages.

Der Erfindung liegt die Aufgabe zugrunde, die Strömungscharakteristik innerhalb des Headers zu verbessern.The invention has for its object to improve the flow characteristics within the header.

Diese Aufgabe wird dadurch gelöst, dass der Header so ausgebildet ist, dass die Zylinderachse innerhalb des Zylindersegments verläuft. Der Querschnitt des Headers wird also durch mehr als einen Halbkreis gebildet. Sein Öffnungswinkel an der Seite des Wärmetauschers ist kleiner als 180°.This object is achieved in that the header is formed so that the cylinder axis extends within the cylinder segment. The cross section of the header is therefore formed by more than one semicircle. Its opening angle on the side of the heat exchanger is less than 180 °.

Damit bildet die zylindermantelsegmentförmige Wand des Headers mit der Seite des Wärmetauscherblocks einen Außenwinkel, der kleiner als 90° ist. Unter "Außenwinkel" wird hier der außerhalb des Headers liegende Winkel verstanden. Für den Fall, dass der betreffende Wandabschnitt des Headers genau mit der Kante des Blocks verbunden ist, wird dieser Außenwinkel durch den Winkel der Wand mit der gedachten Fortsetzung der Blockseite über diese Kante hinaus gebildet.Thus, the cylinder jacket segment-shaped wall of the header with the side of the heat exchanger block forms an outer angle which is smaller than 90 °. "Outside angle" is understood to mean the angle outside the header. In the event that the relevant wall portion of the header is accurately connected to the edge of the block, this outer angle is formed by the angle of the wall with the imaginary continuation of the block side beyond this edge.

Die nicht senkrechte Verbindung der Headerwand mit der Blockseite bewirkt, dass der Strömungsquerschnitt in dem Header vergrößert werden kann, ohne dass dabei seine dem Wärmetauscherblock zugewandte Grundfläche erhöht werden muss. Somit wird eine verbesserte Strömungscharakteristik im Inneren des Headers erzielt, die wiederum einen verringerten Druckverlust und eine gleichmäßigere Verteilung des Fluids auf die Passagen bewirkt.The non-perpendicular connection of the header wall to the block side causes the flow area in the header to be increased without causing its the base plate facing the heat exchanger block must be increased. Thus, an improved flow characteristic is achieved inside the header, which in turn causes a reduced pressure loss and a more uniform distribution of the fluid to the passages.

Beispielsweise wird gemäß der Erfindung statt eines Halbzylinders mehr als die Hälfte eines Zylindermantels als Header verwendet. Verschiebt man die Zylinderachse des Headers von der Seite des Wärmetauschers bei gleich bleibendem Durchmesser um etwa 10 % des Zylinderdurchmessers, kann der Druckverlust um etwa 35 % vermindert werden. Dieser Vorteil wird sogar bei gleicher Nennweite des Headers (also gleichen Anschlussmaßen und gleicher Wandstärke) und sogar verringerter Grundfläche erzielt. Darüber hinaus kann diese Exzentrizität stufenlos variiert werden. Im Gegensatz zu der Variation der Nennweite, die nur in größeren Sprüngen möglich ist, kann der Strömungsquerschnitt des Headers damit gezielt an die jeweilige Anwendung angepasst und insbesondere eine Fehlverteilung effizient vermieden werden.For example, according to the invention, more than half of a cylinder jacket is used as a header instead of a half cylinder. If you move the cylinder axis of the header from the side of the heat exchanger with a constant diameter by about 10% of the cylinder diameter, the pressure loss can be reduced by about 35%. This advantage is achieved even with the same nominal size of the header (ie the same connection dimensions and the same wall thickness) and even reduced footprint. In addition, this eccentricity can be varied continuously. In contrast to the variation of the nominal size, which is possible only in larger jumps, the flow cross-section of the header can thus specifically adapted to the particular application and in particular a misallocation can be efficiently avoided.

Die Erfindung kann aber auch auf andere Header-Formen angewendet werden, beispielsweise solche mit ovalem, asymmetrischem und/oder eckigem Querschnitt.However, the invention can also be applied to other types of headers, for example those with an oval, asymmetrical and / or angular cross-section.

Vorzugsweise beträgt der Außenwinkel zwischen der zylindermantelsegmentförmigen Wand des Headers und der Seite des Wärmetauscherblocks 87° oder weniger, insbesondere 81° oder weniger, insbesondere 75° oder weniger und ist mindestens gleich 40°, insbesondere mindestens gleich 55°, insbesondere mindestens gleich 65°.Preferably, the outer angle between the cylinder jacket segment-shaped wall of the header and the side of the heat exchanger block is 87 ° or less, in particular 81 ° or less, in particular 75 ° or less, and is at least equal to 40 °, in particular at least equal to 55 °, in particular at least equal to 65 °.

Vorzugsweise sind die zylindermantelsegmentförmige Wand (7) des Headers (2) und/oder der Wärmetauscherblock aus Aluminium hergestellt. Es handelt sich also um einen Aluminium-Plattenwärmetauscher, wie er beispielsweise in " The Standards of the Brazed Aluminium Plate-Fin Heat Exchanger Manufacturers' Association, ALPEMA", Second Edition, 2000 grundsätzlich beschrieben ist. Hierbei ist es günstig, wenn zylindermantelsegmentförmige Wand (7) des Headers (2) und der Wärmetauscherblock kraftschlüssig miteinander verbunden sind, beispielsweise durch eine Löt- oder Schweißverbindung.Preferably, the cylinder jacket segment-shaped wall (7) of the header (2) and / or the heat exchanger block are made of aluminum. It is therefore an aluminum plate heat exchanger, such as in " The Standards of the Brazed Aluminum Plate-Fin Heat Exchanger Manufacturers' Association, ALPEMA, Second Edition, 2000 is basically described. In this case, it is favorable if the cylinder-jacket-segment-shaped wall (7) of the header (2) and the heat exchanger block are non-positively connected with one another, for example by means of a soldered or welded connection.

In den Figuren sind lediglich die für die Erläuterung der Erfindung wichtigen Teile dargestellt, der quaderförmige Wärmetauscherblock 1, der erfindungsgemäß ausgestaltete Header 2, der Fluidanschluss 3 und die dort anschließende Rohrleitung 4. Der dargestellte Header kann als Ein- oder Auslass für ein Fluid dienen. Selbstverständlich weist der erfindungsgemäße Plattenwärmetauscher weitere Header auf. Diese können konventionell oder ebenso wie der dargestellte Header ausgeführt sein. Jede Mischung zwischen erfindungsgemäßen und konventionellen Headern ist im Rahmen der Erfindung möglich.In the figures, only the parts important for the explanation of the invention are shown, the cuboid heat exchanger block 1, the inventively designed header 2, the fluid port 3 and the subsequent there piping 4. The illustrated header can serve as an inlet or outlet for a fluid. Of course, the plate heat exchanger according to the invention further headers. These may be conventional or just like the header shown. Any mixture between inventive and conventional headers is possible within the scope of the invention.

Der Header 2 ist an der Seite 5 des Blocks 1 angeordnet und in Form eines Zylindersegments mit einem Öffnungswinkel 6 von mehr als 180°, beispielsweise etwa 200° ausgebildet. Der Header 2 wird durch eine zylindermantelsegmentförmige Wand 7 und durch eine ebene Fläche 12 begrenzt. Letztere verläuft auf der Seite 5 des Wärmetauscherblocks 1. Die zylindermantelsegmentförmige Wand 7 des Headers 2 bildet mit der Seite 5 einen Außenwinkel 8. (Um den Außenwinkel sichtbar zu machen ist in Figur 2 eine Tangentenfläche 9 der Headerwand 7 eingezeichnet.)The header 2 is arranged on the side 5 of the block 1 and formed in the form of a cylinder segment with an opening angle 6 of more than 180 °, for example about 200 °. The header 2 is bounded by a cylinder jacket segment-shaped wall 7 and by a flat surface 12. The latter runs on the side 5 of the heat exchanger block 1. The cylinder jacket segment-shaped wall 7 of the header 2 forms with the side 5 an outer angle 8. (In order to make the outer angle visible, a tangent surface 9 of the header wall 7 is shown in FIG.

Die Zylinderachse 13, also die Symmetrieachse des Zylindermantels 7, verläuft innerhalb des Headers 2 mit Abstand 11 zu der ebenen Fläche 12.The cylinder axis 13, that is to say the axis of symmetry of the cylinder jacket 7, extends within the header 2 at a distance 11 from the flat surface 12.

Die beiden Ausführungsbeispiele unterscheiden sich durch die Ausrichtung des Fluidanschlusses 3. In Figur 1 ist der Fluidanschluss 3 senkrecht zur Seite 5 des Blocks 1 orientiert. Das Fluid strömt also über die Rohrleitung 4 parallel zur Seite 5 zu beziehungsweise ab. Insbesondere wenn es sich um eine Zuleitung handelt, befindet sich in der Rohrleitung 4 ein Leitblech 10, wie es in der älteren deutschen Patentanmeldung 102005055676.0 (internes Aktenzeichen der Anmelderin: P05271-DE/AVA, Anmeldetag: 22.11.2005) und den dazu korrespondierenden Anmeldungen beschrieben ist. Das Leitblech ist im vorliegenden Fall nicht auf der Zylinderachse der Rohrleitung, sondern im Abstand 11 zu dieser angeordnet. Die Rohrleitung 4 weist Zylinderform auf und setzt sich nach links fort (in Figur 1 nicht dargestellt).The two embodiments differ by the orientation of the fluid port 3. In Figure 1, the fluid port 3 is oriented perpendicular to the side 5 of the block 1. The fluid thus flows through the pipeline 4 parallel to the side 5 or from. In particular, if it is a supply line, located in the pipe 4, a baffle 10, as in the older German patent application 102005055676.0 (internal file number of the applicant: P05271-DE / AVA, filing date: 22.11.2005) and the corresponding applications. The guide plate is not arranged in the present case on the cylinder axis of the pipeline, but at a distance 11 to this. The pipeline 4 has a cylindrical shape and continues to the left (not shown in FIG. 1).

In der Variante der Figuren 3 und 4 ist der Fluidanschluss 3 dagegen parallel zur Seite 5 ausgerichtet. Das Fluid strömt in den Zeichnungen in vertikaler Richtung durch die Rohrleitung 4 zu beziehungsweise ab.In contrast, in the variant of FIGS. 3 and 4, the fluid connection 3 is aligned parallel to the side 5. The fluid flows in the drawings in the vertical direction through the pipe 4 to or from.

In einer alternativen Ausführungsform der Erfindung, die in den Zeichnungen nicht dargestellt ist, erstreckt sich der Header 2 über die gesamte Seite 5 des Wärmetauscherblocks. Die beiden axialen Kanten der zylinderförmigen Wand des Headers verlaufen in diesem Fall entlang zweier Kanten des Wärmetauscherblocks.In an alternative embodiment of the invention, which is not shown in the drawings, the header 2 extends over the entire side 5 of the heat exchanger block. The two axial edges of the cylindrical wall of the header in this case run along two edges of the heat exchanger block.
