Definitions

  • Heat exchanger device for rapid heating or cooling of fluids
  • the invention relates to a heat exchanger device with which fluids can be cooled or heated very quickly and with great uniformity.
  • Heat exchangers are needed in numerous industrial applications. At the same time, the trend towards ever higher heat transfer rates in a small space is increasing. These requirements are met in particular by micro-heat exchangers. In the process technology, it is also desired that the heat transfer is very uniform, d. H. that no so-called. "hot spots" (hot zones) arise, which can lead to product damage due to an uncontrolled increase in temperature.
  • a microstructured heat exchanger is known from DE 100 22 972 A1, which is composed of small tubes or hollow fibers which are located in a graphite matrix.
  • micro-heat exchangers are also constructed from multiple layers of microstructured layers, the individual layers each having a number of microchannels.
  • the layers are arranged so that the microchannels of adjacent layers are aligned in a simple cross-flow construction, DC construction or countercurrent construction.
  • Such a micro heat exchanger is known from DE 196 08 824 A1.
  • the countercurrent heat exchanger achieves the highest heat exchange capacity per exchange surface. However, it can not be ruled out that inadmissibly high temperature differences can occur at the inlet of the warmer fluid, which leads to damage to the fluid to be heated.
  • the wall temperatures remain in a central region at all points of the heating surface. Due to the rapidly decreasing Temperature difference between the adjacent fluids, the heat exchange performance, however, is relatively poor.
  • the heat exchange rates are between those of the DC heat exchanger and the countercurrent heat exchanger.
  • the full heat exchange surface is not used efficiently because the temperature differences in a quadrant of the heat exchange surface are extremely small or no longer exist.
  • micro-heat exchanger no sufficient or no thermal insulation to the environment, which is particularly in modular microreaction systems, as they are, for. B. from DE 202 01 753 Ul, very detrimental effect, because it comes to an intensive heat exchange with adjacent modules.
  • the invention is based on the object, with the highest possible heat transfer performance, d. H. the creation of a large heat transfer surface to achieve an extremely low pressure drop for both the process fluid and the heat transfer fluid.
  • the heat exchanger is constructed of a stack of films or plates, in each of which adjacent channels for the fluids are formed, wherein the channels of the superimposed films or plates intersect.
  • the heat transfer fluid flows in the adjacent channels of a film or plate in partial streams in anti-parallel to each other, while in the overlying and underlying film or plate, the process fluid flows transversely to the heat transfer fluid in parallel in the adjacent channels.
  • the inlet conditions of each partial flow of the process fluid over the entire volume of the heat exchanger are produced at each crossing point of heat transfer fluid and process fluid Countercurrent heat exchanger with the known high temperature differences between heat transfer fluid and process fluid. Due to the numerous points of intersection of heat transfer fluid and process fluid, this results in an optimum temperature difference between heat transfer fluid and process fluid over the entire volume of the heat exchanger and thus an extremely high heat transfer performance per unit volume and at the same time an absolutely uniform heat transfer over the entire volume of the heat exchanger.

  • the antiparallel flow of the partial flows of the heat transfer fluid can also be seen from Fig. 4, which shows a section along the line BB in Fig. 1, Fig. 4 shows only a partial section and the top and bottom edge portions of the heat exchanger unit 1 are not reproduced.
  • the discharge of the heat transfer fluid W takes place on the opposite side by a line 4a, which is formed by corresponding openings in the superimposed films F and also in the plane of FIG. 2 from top to bottom or vice versa respectively transverse to the channels 2 and 3 runs.
  • the adjacent in Fig. 2 channels 3, flow through the partial streams W 2 from right to left, are supplied by a formed by apertures 5 line, which lies in front of and behind the line 4a.

  • FIG. 5 shows the flow in the core region of the heat exchanger only by arrows, with the process fluid P flowing in parallel through the channels 2 arranged in rows and the heat transfer fluid W transversely thereto in each case in antiparallel flow of the partial streams Wi and W 2 .
  • Fig. 6 shows in a schematic perspective view of a heat exchanger unit 1.
  • the core of the heat exchanger is formed by the intersecting channels 2 and 3, which are each arranged in rows 20 and 30, wherein the heat transfer fluid W in adjacent channels 3 antiparallel or in Countercurrent is guided while the process fluid P flows in DC through the adjacent channels 2.

  • the structure described allows for a variety of customization options by changing the number of films F and the channels 2, 3 and adapted to the respective desired flow rates. By increasing the stack of films or thin plates F, the capacity of the micro heat exchanger 1 can be increased accordingly. It is also possible to flow both the process fluid P and the heat transfer fluid W antiparallel through the respective rows 20, 30 of channels 2, 3.
