Description

Stand der TechnikState of the art

Die Erfindung betrifft den Gegenstand einer Wärmeübertragerplatine gemäß dem Ober­ begriff des Patentanspruchs.The invention relates to the subject of a heat exchanger board according to the Ober concept of claim.

Es ist bekannt, Wärmeübertrager für die verschiedensten Einsatzbereiche zu benutzen. Die grundsätzliche Funktionsweise besteht darin, dass ein Medium mit einer hohen Temperatur durch ein anderes Medium mit einer niedrigen Temperatur gekühlt wird, wobei sich das zweite Medium erwärmt oder umgekehrt. Dies geschieht normalerweise, ohne dass die Medien miteinander in Kontakt kommen. Wärmeübertrager finden daher z. B. Verwendung in Häusern, wo die in das Haus einströmende kalte Frischluft im Wärmeübertrager von der ausströmenden warmen Luft erwärmt wird. Ein derartiger Wärmeübertrager ist durch die DE 43 33 904 C2 bekanntgeworden. Dieser Wärmeübertrager für insbesondere zwei durchströmende Fluide mit parallelen Strömungskanälen ist im Querschnitt aus schichtweise aufeinander liegenden Tafeln mit mäanderförmigem Profil ausgebildet. Dabei deckt eine aufliegende Tafel die Strömungskanäle der darunterliegenden Tafel ab. Seitlich benachbarte Strömungskanäle sind von unterschiedlichen Fluiden durchströmbar. Die Tafeln sind aus dünnen Blechen gefertigt. Die mäanderförmigen Profile können nur unter sehr großem Aufwand gefertigt werden. It is known to use heat exchangers for a wide variety of applications to use. The basic mode of operation is that a medium with a high temperature cooled by another medium with a low temperature the second medium warms up or vice versa. this happens usually without the media coming into contact with each other. Heat exchangers therefore find z. B. Use in homes where those in the home incoming cold fresh air in the heat exchanger from the outflowing warm Air is heated. Such a heat exchanger is known from DE 43 33 904 C2 known. This heat exchanger for two flowing in particular The cross-section of fluids with parallel flow channels consists of layers superimposed panels with a meandering profile. It covers an overlying panel covers the flow channels from the underlying panel. Laterally Different fluids can flow through adjacent flow channels. The Sheets are made from thin sheet metal. The meandering profiles can only are manufactured with great effort.  

Weiterhin ist aus der GB 1 336 448 ein Wärmeübertrager bekannt, der aus einem Stapel von paarweise verbundenen Platten aufgebaut ist. Der Querschnitt der Platten stellt ein kurvenförmiges Profil dar. Die Strömungskanäle werden durch das Verbinden von zwei Platten gebildet. Das kurvenförmige Querschnittsprofil bietet wiederum nur eine kleine Wärmeübertragungsfläche. Außerdem werden durch das kreuzweise Durchströmen kleinere Wärmestromdichten als bei einem Gegenstromwärmeübertrager erreicht.Furthermore, a heat exchanger is known from GB 1 336 448, which consists of a Stack of plates connected in pairs is built. The cross section of the plates represents a curved profile. The flow channels are through the Connect formed by two plates. The curved cross-sectional profile offers again only a small heat transfer area. In addition, the cross flow through smaller heat flux densities than one Counterflow heat exchanger reached.

Aufgabe der ErfindungObject of the invention

Aufgabe der Erfindung ist es, das Profil der Platinen zu verbessern, so dass eine optimale Wärmeübertragung und eine stabile Lage der übereinanderliegenden Platinen möglich wird.The object of the invention is to improve the profile of the boards, so that a optimal heat transfer and a stable position of the superimposed ones Circuit boards becomes possible.

Gegenstand und Vorteile der ErfindungObject and advantages of the invention

Diese Aufgabe wird durch die Merkmale des Patentanspruchs, i. w durch die gute gegenseitige Abstützung der Platinen untereinander gelöst und ist deshalb besonders zum Einsatz für hohe Drücke in den Strömungskanälen geeignet. Die Lebensdauer eines derart hergestellten Wärmeübertragers ist größer als bei Wärmeübertragern aus Metall.This object is achieved by the features of claim i. w through the good mutual support of the boards solved among themselves and is therefore particularly suitable for high pressures in the Suitable flow channels. The lifespan of a manufactured in this way Heat exchanger is larger than metal heat exchangers.

Eine Ausführungsform der Platine stellt sich so dar, dass die Hohlräume Strömungskanäle bilden, die über ihren axial ausgerichteten Verlauf einen zumindest abschnittsweise ausgebildeten seitlichen Versatz aufweisen, der bei aufeinanderliegenden Platinen an einer Kante eines Strömungskanals einer darüber oder darunter angeordneten Platine zur Anlage kommt. Ein seitlich ausgebildeter Versatz hat den Vorteil, dass die Strömung im Kanal durch den Versatz gestört wird. Diese Störung bewirkt eine Verwirbelung der strömenden Medien, was die Wärmeübergangszahl erhöht. Außerdem bewirkt der Versatz eine Verlängerung des Strömungswegs. Ein längerer Strömungsweg bedeutet eine längere Aufenthaltszeit im Wärmeübertrager und damit eine längere Wärmeübertragungszeit. Ein weiterer Vorteil des Versatzes besteht darin, dass er ein Ineinanderrutschen zweier aufeinander liegender Platinen verhindert. Der Versatz kann sich über relativ kurze Strecken oder über die gesamte Länge der Platine erstrecken. Die Strömungskanäle verlaufen in der Regel parallel zueinander.An embodiment of the circuit board is such that the cavities Form flow channels that at least over their axially aligned course sectionally formed lateral offset, which at superimposed boards on one edge of a flow channel one above or the board below it comes to rest. A laterally trained Offset has the advantage that the flow in the channel is disturbed by the offset. This disturbance causes a swirling of the flowing media, causing the Heat transfer coefficient increased. In addition, the offset extends the Flow path. A longer flow path means a longer stay in the Heat exchanger and thus a longer heat transfer time. Another advantage of the offset is that it is a slipping of two on top of each other horizontal boards prevented. The offset can vary over relatively short distances or extend the entire length of the board. The flow channels run in the Usually parallel to each other.

Zeichnungdrawing

Ein Ausführungsbeispiel der erfindungsgemäßen Platinen für Wärmeübertrager ist in den Figuren der Zeichnung stark schematisiert dargestellt und wird in der nachfolgenden Beschreibung erläutert. Es zeigt:An embodiment of the circuit boards for heat exchangers according to the invention is shown in the figures of the drawing are shown in a highly schematic manner and is shown in the following description explained. It shows:

Fig. 1 eine perspektivische Ansicht zweier Kanalprofile; Figure 1 is a perspective view of two channel profiles.

Fig. 2 einen Querschnitt durch die Kanalprofile von drei aufeinander gestapelten Platinen mit seitlichem Versatz. Fig. 2 shows a cross section through the channel profiles of three stacked boards with lateral offset.

Beschreibung des AusführungsbeispielsDescription of the embodiment

Fig. 1 zeigt Kanalprofile 1, 2 einer oberen und einer unteren Basisfläche. Ein Wärmeübertrager mit Strömungskanälen 3, die einen quadratischen oder rechteckigen Querschnitt aufweisen, wird dadurch realisiert, dass zwei Platinen mit den Kanalprofilen 1, 2 in Kontakt gebracht werden. Die Strömungskanäle 3 werden gebildet, indem das obere Kanalprofil 1 die Strömungskanäle des unteren Kanalprofils 2 abdeckt. Um zu verhindern, dass die Kanalprofile 1, 2 ineinander rutschen, wird im oberen Kanalprofil 1 ein Versatz 4 nach rechts und im unteren Kanalprofil 2 ein Versatz 5 nach links angebracht. Fig. 1 shows channel profiles 1, 2 an upper and a lower base surface. A heat exchanger with flow channels 3 , which have a square or rectangular cross section, is realized in that two boards are brought into contact with the channel profiles 1 , 2 . The flow channels 3 are formed by the upper channel profile 1 covering the flow channels of the lower channel profile 2 . In order to prevent the channel profiles 1 , 2 from sliding into one another, an offset 4 to the right is applied in the upper channel profile 1 and an offset 5 to the left in the lower channel profile 2 .

Fig. 2 zeigt einen Querschnitt durch drei aufeinander liegende Kanalprofile 1, 2, 6 gemäß Fig. 1. Der Querschnitt befindet sich in einer Ebene, die den Versatz 4, 5 enthält. Der Versatz 5 ist gegenüber dem Versatz 4 nach links verschoben, so dass eine stabile Auflage für das Kanalprofil 1 auf dem Kanalprofil 2 entsteht. Die Kanalprofile 1, 2 können an dieser Stelle auch miteinander verklebt oder verschweißt werden. Der Wärmeübertrager eignet sich dadurch besonders zum Einsatz für hohe Drücke in den Strömungskanälen. Andererseits entsteht eine kleine Lücke zwischen den Kanten 7 und 8. Hier kann das Medium von einer Ebene in die andere gelangen, was zu Spiralströmungen und somit weiteren Turbulenzen führt, die sich günstig auf den Wärmeübertragungsprozess auswirken. FIG. 2 shows a cross section through three superimposed channel profiles 1 , 2 , 6 according to FIG. 1. The cross section is in a plane that contains the offset 4 , 5 . The offset 5 is shifted to the left relative to the offset 4 , so that a stable support for the channel profile 1 on the channel profile 2 is created. The channel profiles 1 , 2 can also be glued or welded together at this point. This makes the heat exchanger particularly suitable for use at high pressures in the flow channels. On the other hand, there is a small gap between edges 7 and 8 . Here, the medium can get from one level to the other, which leads to spiral flows and thus further turbulence, which has a favorable effect on the heat transfer process.
