Description

  • Die Erfindung betrifft einen Wärmetauschermodul, der durch Stapeln von mit Durchbrüchen versehenen Folienkarten und anschließendes Verbinden der einzelnen Folienkarten des Folienkartenstapels hergestellt ist. The invention relates to a heat exchanger module, which is produced by stacking sheet cards provided with openings and subsequently joining the individual sheet cards of the sheet stack of cards.
  • Unter Folienkarten sollen nachfolgend Karten aus grüner Keramik, aus Metall wie zB Legierungen aus Kupfer, aus Stahl, aus Aluminium oder aus Kunststoff und unter Verbinden Laminieren mit anschließendem Brennen, Löten, Schweißen, Kleben oder mechanisches Verbinden unter Zwischenlegen von Dichtungen verstanden werden. be sheet cards are subsequently cards from green ceramic, made of metal such as alloys of copper, steel, aluminum or plastic and bonding lamination with subsequent burning, soldering, welding, gluing or mechanical bonding understood with the interposition of seals.
  • Wärmetauschermodule der genannten Art sind aus der DE-A-36 43 750 bekannt. Heat exchanger modules of said type are known from DE-A-36 43 750th Die keramischen Folienkarten, aus denen die bekannten Wärmetauschermodule hergestellt sind, weisen erste Ausnehmungen auf, die bei gestapelten Karten durchgehende Kanäle bilden. The ceramic sheet cards from which the known heat exchanger modules are made comprise first recesses, form the continuous in stacked cards channels. Um die ersten Ausnehmungen herum sind zweite Ausnehmungen so angeordnet, daß sich zwei der Ausnehmungen benachbarter Karten teilweise überlappen, wobei sich Kanäle ausbilden, die sich senkrecht zu den durchgehenden Kanälen erstrecken und diese umgeben. To the first recesses are arranged second recesses so that two of the recesses of adjacent cards partially overlap, said channels forming, which extend perpendicular to the through channels and surround therearound. Nachteilig ist der große Strömungswiderstand in den Kanälen, die durch die zweiten Ausnehmungen gebildet werden. A disadvantage is the large flow resistance in the channels, which are formed by the second recesses. Hier will die Erfindung Abhilfe schaffen. The invention aims to provide a remedy.
  • Die Aufgabe wird durch einen Wärmetauschermodul der eingangs beschriebenen Art gelöst, der dadurch gekennzeichnet ist, daß jede Folienkarte oder Gruppe von Folienkarten des Folienkartenstapels gegenüber der vorhergehenden Folienkarte oder Gruppe von Folienkarten um eine gemeinsame Achse um einen Winkel α zwischen 20 und 30° gedreht angeordnet ist, wobei die Durchbrüche spiralförmige Kanäle ausbilden. The object is achieved by a heat exchanger module of the initially described type which is characterized in that each sheet card or group of sheet cards of the sheet stack of cards with respect to the preceding sheet card or group of sheet cards about a common axis α by an angle is arranged rotatable between 20 and 30 ° wherein the openings forming helical channels.
  • Die Folienkarten können kreisförmig ausgebildet sein und konzentrisch zu ihrer Kontur Kreissegmente, insbesondere zwei symmetrisch zueinander angeordnete Kreissegmente als Durchbrüche aufweisen. The film cards can be circular and have concentrically to their contour circle segments, in particular two symmetrically arranged circular segments as openings.
  • Die durch die Erfindung erreichten Vorteile sind im wesentlichen in der Verminderung des Strömungswiderstandes zu sehen. The advantages achieved by the invention are to be seen essentially in reducing the flow resistance. Darüberhinaus kann der Modul aus einem Kartenmuster ohne Wenden der Karte aufgebaut werden. In addition, the module can consist of a card pattern without turning the card to be established. Derartige Wärmetauschermodule eignen sich aufgrund ihrer guten Anpassbarkeit auch an stark unterschiedliche Volumenströme für den Einsatz flüssig/flüssig, flüssig/gasförmigen und gasförmigen/gasförmigen Wärmetausch sowie für Kondensations- und Verdampfungsvorgänge selbst bei hohen Drücken und der Verwendung stark korrosiver Medien. Such heat exchanger modules are suitable because of their good adaptability also greatly different flow rates for use liquid / liquid, liquid / gas and gas / gas heat exchange and for condensation and evaporation processes even at high pressures and the use of highly corrosive media. Der Wärmetauschermodul findet Anwendung in Kraftfahrzeugen aller Art, Schiffen, Flugzeugen und Schienenfahrzeugen. The heat exchanger module is used in motor vehicles of all types, ships, aircraft and railway vehicles.
  • Im folgenden wird die Erfindung anhand von lediglich einen Ausführungsweg darstellenden Zeichnungen näher erläutert. In the following the invention will be explained in more detail only one embodiment illustrative drawings.
  • Die Figur 1 zeigt einen Wärmetauschermodul in räumlicher Darstellung, teilweise aufgeschnitten. 1 shows a heat exchanger module in a spatial representation, partially cut away.
  • Die Figur 2 zeigt das Stapeln der den Wärmetauschermodul bildenden grünen Folienkarten in räumlicher Darstellung teilweise explodiert und aufgeschnitten. 2 shows the stacking of the heat exchanger module forming green sheet cards in a spatial representation partially exploded and cut open.
  • Der Wärmetauschermodul 1 ohne Anschlußhauben ist insbesondere aus grünen keramischen Folienkarten 2 hergestellt. The heat exchanger module 1 without connecting hood is in particular made of ceramic green sheet cards. 2 Die Folienkarten 2 weisen kreissegmentartige Durchbrüche 3 auf, die symmetrisch zueinander und konzentrisch zur kreisförmigen Kontur der Folienkarte 2 angeordnet sind. The sheet cards 2 are of circular-segment-like openings 3, which are arranged symmetrically to each other and concentric to the circular contour of the film card. 2 Die Folienkarten 2 werden einzeln und um einen Winkel α, zB 20° gegenüber der vorhergehenden Karte übereinander gelegt, wobei sich spiralförmige (wendeltreppenartige) Kanäle 4 (Doppelhelix) bilden. The film cards 2 are individually and α at an angle, for example, from the previous map set 20 ° to each other with a spiral-shaped (spiral staircase-like) channels 4 (double helix) form. Die einzelnen Karten 2 können auch zu Gruppen aus zwei und mehr Karten zusammengefaßt werden, die dann ihrerseits wie bei den einzelnen Karten beschrieben gestapelt werden. The individual cards 2 can also be groups of two or more cards are summarized, which are then stacked as described in the individual cards themselves. An der Treppenstruktur der Kanäle 4 erkennt man die einzelnen Karten 2 bzw. die Gruppen aus Karten, aus denen sich der Wärmetauschermodul 1 zusammensetzt. At the stepped structure of the channels 4 can be seen the individual cards 2 or the groups of cards, of which the heat exchanger module 1 composed. Die Folienkarten können auch in gewissen Grenzen eine beliebige Kontur besitzen, ebenso ihre Durchbrüche. The film maps can be of any shape, as their breakthroughs within certain limits. Die Kontur der Karte 2 kann mit Ausnehmungen 5 versehen sein, die beim Stapeln der Karten auf der äußeren Oberfläche des Wärmetauschermoduls durchgehende Rinnen 6 bilden. The contour of the card 2 may be provided with recesses 5 which form the solid when stacking the cards on the outer surface of the heat exchanger module gutters. 6 Ferner kann die Karte 2 neben den segmentartigen Durchbrüchen 3 noch Ausnehmungen 7 aufweisen, die ebenfalls im Winkel α versetzt sind und dadurch im Modul 1 durchgehende Kanäle 8 bilden. Further, the card 2 next to the segment-like apertures 3, has recesses 7 can have, which are also offset at an angle α, thereby forming continuous channels in the module 1. 8 Durch Variationen der Abmessungen der Durchbrüche und/oder des Drehwinkels α kann der Wärmetauschermodul sehr flexibel an unterschiedliche Aufgabenstellungen angepaßt werden. the heat exchanger module may α by variations in the dimensions of the apertures and / or the angle of rotation can be very flexibly adapted to different tasks. Es kann auch vorteilhaft sein, die Drehachse 9 außermittig festzulegen. It may also be advantageous off-center to define the axis of rotation. 9 Die einzelnen Folienkarten 2 werden durch keramischen Brand zu einem monolithischen Wärmetauschermodul oder durch Löten, Schweißen, Kleben oder mechanisches Verbinden, zB durch Zuganker unter Zwischenlegen von Dichtungen zwischen die einzelnen Karten zu einem Wärmetauschermodul verbunden. The individual sheet cards 2 are connected by ceramic firing to form a monolithic heat exchanger module, or by soldering, welding, gluing or mechanical bonding, for example by tie rods with the interposition of seals between the individual cards to a heat exchanger module. Die Karten 2 mit den Durchbrüchen 3 können durch Gießen, Sägen, Fräsen, Drehen, Tiefziehen, Prägen, Lasern, Stanzen oder Flüssigkeitsstrahlschneiden hergestellt werden. The card 2 with the apertures 3 may be formed by casting, cutting, milling, turning, deep-drawing, stamping, laser cutting, punching or fluid jet cutting.
