Definitions

  • the invention relates to a corrugated heat exchanger body according to the preamble of claims 1, 2 or 3.
  • Corrugated heat exchangers in the present sense are to be, for example, so-called corrugated fins which are inserted between the flat tubes arranged in series in air-cooled coolers in order to ensure the heat exchange between the medium in the flat tubes and the cooling air flowing through the corrugated fins.
  • the heat exchanger walls mentioned are the broad sides of the flat tubes.
  • the vertices are arched.
  • Other corrugated heat exchangers are often referred to as fins or also as internal inserts and are located inside pipes or in channels formed by plates, for example in plate heat exchangers which can be found as oil coolers or the like. In such cases, the heat exchanger walls are the individual plates stacked one inside the other. The vertices are mostly bent in a U shape.
  • the heat exchange bodies (corrugated fins) defined in the preamble are known from US Pat. No. 3,298,432.
  • the structures in the flanks are very fine ribs in the US script, which run obliquely in the manner of a herringbone pattern. The pattern is embossed into the metal strip and then the wave shape of the corrugated fin is produced, so that the arrangement direction of the structures in one flank intersects with the arrangement direction of the structures in the following flank. Since the structures in the US script are supposed to be very fine, there is an improved efficiency of the heat exchange in the area near the wall, but the crossing of the same will hardly have any noticeable additional effect.
  • the corrugated ribs have a similar herringbone structure, with several herringbone structures being arranged one behind the other because of the greater width of the metal strip, so that parallel zigzag lines result.
  • the herringbone pattern is much coarser than that from the first document. A crossing of the arrangement direction from flank to flank is not provided in the DE document.
  • the heat exchange bodies described are to be developed in accordance with the object of the present invention in such a way that they promise a further improvement with regard to their heat exchange efficiency.
  • This object is achieved by the characterizing part of claim 1 or claim 2 or claim 3. All three proposed solutions independently work in conjunction with the generic term.
  • the characterizing part of claim 1 it is provided that the elements of the structures are beads or waves or the like which provide the flow channel with alternating constrictions and extensions, with adjacent flow channels being essentially separated from one another in terms of flow technology. It was found that heat exchangers designed in this way have better heat transfer. This could be due to the fact that the flow passing through the flow channel between the flanks is at least partially set in rotation, which improves the exchange with the flow near the wall.
  • the elements of the structures are beads or waves that point into the flow channel, as can be seen from cross sections made at different heights, constrictions and widenings of the flow channel occur through the flow channel, as seen in the flow direction, which have a favorable effect can be assigned.
  • the elements of the structures are sections that fluidly connect adjacent flow channels with one another. It has been found that such intersecting cuts from side to side in their arrangement direction can contribute to improved heat transfer.
  • the cuts themselves are of a known nature and are bent out of the surface of the flank, which results in openings in the flank which connect adjacent flow channels to one another.
  • the elements of the structures are beads or waves, in which cuts lying in the direction of arrangement of the beads or waves are arranged.
  • the cuts can be in the wave valleys or on the wave crests or anywhere within the waves.
  • the cuts are provided with an angle of attack to the flank surface in order to generate a turbulent flow.
  • the cuts of the invention preferably have the same angle of attack within one flank and also in adjacent flanks.
  • the beads and the cuts have the same arrangement direction, so that, seen in a cross section, the cuts and the beads in the flanks are arranged parallel to one another. The directions of arrangement of the cuts and beads in neighboring flanks intersect. It is also considered advantageous that, in the case of several groups of inclined structures in one flank, opposite angles of inclination of the inclined structures from one group to the next group are provided, wherein between the groups, the flanks are either designed without a structure or, if necessary, can have stiffening elements. The length of the elements of the structures is shorter at their beginning and at their end than in the adjoining main structure area in order to make the best possible use of the area of the flanks.
  • the length of the elements in the main structure area should preferably be the same size and be at least 70% of the wave height.
  • the angle of inclination of the oblique structures with respect to the vertical is preferably not greater than 45 °.
