Definitions

  • the invention relates to a heat exchanger module which is produced by stacking foil cards provided with openings and then connecting the individual cards of the card stack.
  • Heat exchanger modules of the type mentioned are known from DE-A-36 43 750.
  • the ceramic film cards from which the known heat exchanger modules are made have first recesses which form continuous channels in stacked cards.
  • second recesses are arranged such that two of the recesses of adjacent cards partially overlap, with channels being formed which extend perpendicularly to and surround the continuous channels.
  • the large flow resistance in the channels, which are formed by the second recesses, is disadvantageous.
  • the invention seeks to remedy this.
  • each film card or group of film cards of the stack is arranged rotated by an angle ⁇ between 0 and 30 ° about a common axis relative to the previous film card or group of film cards , wherein the openings form spiral channels.
  • the foil cards can be circular and have circular segments concentric with their contour, in particular two circular segments arranged symmetrically to one another as openings.
  • the module can be constructed from a card pattern without flipping the card. Because of their good adaptability, such heat exchanger modules are also suitable for use with widely differing volume flows for the use of liquid / liquid, liquid / gaseous and gaseous / gaseous heat exchange as well as for condensation and evaporation processes even at high pressures and the use of highly corrosive media.
  • the heat exchanger module is used in all types of motor vehicles, ships, aircraft and rail vehicles.
  • Figure 1 shows a heat exchanger module in a spatial representation, partially cut away.
  • FIG. 2 shows the stacking of the green film cards forming the heat exchanger module, partially exploded and cut open in a spatial representation.
  • the heat exchanger module 1 without connection hoods is made in particular from green ceramic foil cards 2.
  • the film cards 2 have circular segment-like openings 3, which are arranged symmetrically to one another and concentrically to the circular contour of the film card 2.
  • the foil cards 2 are placed one above the other and at an angle ⁇ , for example 20 ° above the previous card, with spiral (spiral staircase) channels 4 (double helix) being formed.
  • the individual cards 2 can also be combined into groups of two or more cards, which in turn are then stacked as described for the individual cards.
  • the staircase structure of the channels 4 shows the individual cards 2 or the groups of cards from which the heat exchanger module 1 is composed.
  • the foil cards can also have any contour within certain limits, as can their openings.
  • the contour of the card 2 can be provided with recesses 5 which form continuous channels 6 when the cards are stacked on the outer surface of the heat exchanger module. Furthermore, in addition to the segment-like openings 3, the card 2 can also have recesses 7 which are likewise offset at an angle ⁇ and thereby form continuous channels 8 in the module 1. By varying the dimensions of the openings and / or the angle of rotation ⁇ , the heat exchanger module can be adapted very flexibly to different tasks. It can also be advantageous to set the axis of rotation 9 off-center.
  • the individual foil cards 2 are connected by ceramic firing to form a monolithic heat exchanger module or by soldering, welding, gluing or mechanical connection, for example by tie rods with the interposition of seals between the individual cards to form a heat exchanger module.
  • the cards 2 with the openings 3 can be produced by casting, sawing, milling, turning, deep drawing, embossing, lasering, punching or liquid jet cutting.
