Definitions

  • the invention relates to a flow channel for a heat exchanger in which Turbulence generating elevations are located, which has a lateral surface and a Have connecting surface, wherein at least some surveys either in a wall of the flow channel are formed and attached to the Supported opposite wall of the same flow channel and thus are connected or formed in both walls, support each other and connected to each other.
  • Such flow channels are often found in plate heat exchangers.
  • One suitable example has been described in EP 0 623 798 B1.
  • the turbulence-generating elevations in a wall of the flow channel educated. They are supported by the smooth, opposite wall of the Flow channel, and they are soldered to it.
  • Turbulence generating elevations in flow channels serve as the term already says, the generation of turbulence in the flow channel flowing medium, with the aim of the efficiency of heat exchange with to raise the medium flowing in the adjacent flow channel.
  • these surveys contribute to the stability of the heat exchanger, as they are in usually metallically connected to the walls.
  • the inventive solution of the problem is with the characteristics of the Claim 1 reached.
  • the projections or fine structures on the turbulence generating surveys lead to increased turbulence in the medium and thus to a higher cooling capacity.
  • the use of slats, which, as mentioned, often lead to problems regarding the production of the required degree of purity, can be avoided in many cases by the invention.
  • the fine structures according to the invention at the turbulence-generating Elevations are incorporated in the embossing or forming tool, so that they simultaneously with the production of the heat exchanger plates or the walls of the Flow channels arise.
  • the heat exchanger plates are preferably made produced relatively thin aluminum sheets.
  • the shape of the projections or the fine structures, their arrangement and number can be extremely diverse and depends from the intended use case. Furthermore of course also from the Arrangement and shape of the turbulence-generating elevations themselves. These can have an elongated shape, they can be circular, ultimately they can possess any convenient forms.
  • FIG. 3 depicts an approximately circular turbulence-generating elevation 1 , on which six projections 2 , distributed around the circumference, are arranged.
  • the projections 2 protrude into the flow channel 3 , as shown in principle in FIGS. 5 and 6.
  • the projections 2 have been shown schematically as dashes, from which it should be apparent that in this exemplary embodiment fine, elongated beads are used, which in the production of the (walls) plates 4, 5 form on a press be formed.
  • Figs. 1a, 1b a cross section has been shown by such a bead (projection 2) .
  • the stamp Wi has not been changed compared to the previous version. The material flows into a notch formed in the die Wa .
  • the punch which acts on the inside has a curvature which presses the material into the notch of the die in a targeted manner in order to form the bead 2 .
  • the lateral surfaces 10 of the turbulence-generating elevations 1 were provided with protrusions 2 .
  • the beads 2 (projections) run approximately in a star shape from an imaginary center of the survey 1 apart and end approximately on the flat wall 4 or 5 .
  • the connecting surfaces 11 of the turbulence-generating elevations 1 serve in FIG. 5 the connection with the wall 4, since there are formed only in a wall 5 turbulence-generating elevations 1 . In contrast, serve in Fig.
  • FIG. 4 shows a longitudinally oval turbulence-generating elevation 1 , only to show that its shape is in principle free. There are a total of 16 projections 2 formed on a survey 1 .
  • the heat exchanger in Figs. 5, 6 and 7 is a shellless plate heat exchanger, or a part thereof, in which the heat exchanger plates 4 and 5, as shown in Fig. 5, are set into each other after the pre-assembly of the plate heat exchanger be tightly connected in a soldering process at their oblique edges 6 and at the connecting surfaces 11 .
  • the flow channel 3 has an inlet and an outlet, via a vertically passing through the stack of heat exchanger plates 4, 5 collecting channel and a distribution channel, which, however, were not shown.
  • the flow channel 3 according to the invention may well be located in other heat exchangers and expressly provided for this, for example in such heat exchangers, which have a housing around a stack of plates.
  • heat exchangers which have a housing around a stack of plates.
  • two plates usually form a flow channel 3 between them.
  • the flow channels 3 are also hydraulically connected by means of a collecting channel and a distribution channel. Between the pairs of plates are other flow channels that are hydraulically accessible through the housing.
  • the description of this widely used type of heat exchanger is also not intended to be limiting thereto.
  • the flow channel 3 may for example also be a flat tube whose broad sides represent the walls 4 and 5 .
  • Fig. 7 shows only a part of a heat exchanger plate 4 or 5 of a housing-less plate heat exchanger as a pattern, which has a plurality of arranged in rows 20 elevations 1 , which are all formed with a fine structure 2 .
  • the opening 7 serves for the inflow of the medium into the flow channel 3 .
  • the associated opening for the drain is located at the other end of the heat exchanger plate, not shown.
  • the opening 8 serves the inflow into the adjacent flow channel, not shown. Also, this flow channel is associated with a not shown drain at the other end of the heat exchanger plate.
  • At least some flow channels of the heat exchanger have the described and shown features. Expressly, this can either all Be flow channels of the heat exchanger or recordable only those for a medium. Those for the other medium can be quite different trained, for example, be occupied with slats.
