Definitions

  • the invention relates to plate heat exchangers, preferably those in caseless Type consisting of stacked heat exchanger plates, the at least one Having medium associated openings, wherein the heat exchanger plates so stacked are that the openings lie one above the other and vertically through the stack pass through inlet or outlet channels, and with between them Heat exchanger plates formed flow channels, wherein the inlet and the outlet channel with the medium associated flow channels fluidly is connected and wherein formations are arranged at the edge of the openings.
  • the invention has for its object to provide a plate heat exchanger, which promises a higher efficiency of heat exchange.
  • the solution according to the invention is carried out with the features of the characterizing part of claim 1. Because formations extend upwardly and downwardly below the plane of the heat exchanger plate with the unidirectional formations, as known in the art, disposed about the entire opening and the formations having flow-directing characteristics extending in the other direction , Are arranged only around part of the circumference of the openings, the flow through the flow channels is intensified, so a higher efficiency of the heat exchange is achieved.
  • the proposed design of the heat exchanger plates is very easy to manufacture and therefore helps to keep the costs in a very reasonable frame.
  • the construction according to the invention which allows the formations to be arranged relatively close to the edge of the openings, it has become possible to form relatively small cut-outs around the formations in the fins, which are usually located in the flow channels and promote heat exchange , This means that the non-cut portions of the slats are comparatively larger, which also improves the heat exchange.
  • the formation extending around the entire opening serves to form the inlet or outlet channel by abutting either on an undeformed edge of the opening of the adjacent heat exchanger plate or on an identical formation at the edge of the opening of the adjacent heat exchanger plate.
  • the formations at the openings are in the last-mentioned variant preferably half as high as the height of the flow channel.
  • the shape extending around the entire opening is closer to Edge of the opening arranged as the other molding, extending only a part the extent of the opening extends.
  • the formations preferably merge into one another, such that a cut has an approximately S-shaped shape by both formations.
  • An advantageous alternative provides that between only one part of the Scope extending shape and an identical shape or the undeformed edge of the opening of the adjacent heat exchanger plate a gap is arranged, which is smaller than the height of the associated flow channel.
  • one or more openings are present within the adjacent flow-guiding formations of two heat exchanger plates.
  • the flow directing formation is to extend for about 1/3 to 1/2 of the total circumference of the opening, these formations being positioned so that a substantial portion of the flow is first directed into a corner region of the plate heat exchanger before it can pass to the associated channel.
  • FIG. 1 and 2 differ only with respect to the flows in the plate heat exchanger whose directions are indicated by flow arrows.
  • the solid arrow shows the flow direction in the illustrated flow channel 5 and the dashed arrow the flow direction in the underlying flow channel thirteenth
  • the flow channels 5 for one medium and 13 for the other medium alternate in the embodiment.
  • only four rectangular heat exchanger plates 1 were used, which is sufficient for the purpose of explanation, but otherwise rather is not a practical embodiment.
  • the number of heat exchanger plates 1 is adapted to the intended application, and it will usually be greater than four.
  • the shape of the heat exchanger plates 1 need not necessarily be rectangular. Since, as already mentioned, the exemplary embodiment is a housing-less plate heat exchanger for two media, its heat exchanger plates 1 have four openings 2, 6, 7, which correspondingly form four inlet or outlet channels through the plate heat exchanger, which are identified by reference numbers 3 , 4 , 8, 9 have been marked.
  • the inlet channel 3 is intended for the one medium to which the outlet channel 4 is assigned. These channels 3 , 4 communicate with the flow channels 5 between the heat exchanger plates. 1 Accordingly, the inlet channel 8 is provided for the other medium, which is fluidically connected via the flow channels 13 to the outlet channel 9 . (FIG.
  • the fins 50 could be formed differently than shown, or they could be partially or completely replaced by projections formed in the heat exchanger plates 1 or the like. Furthermore, only a few flow channels 5 could be covered with fins 50 and the other flow channels 13 could have the mentioned projections (nubs). (Not shown)
  • protrusions 10a, 10b have been provided on the edge 11 of all openings 2, 6, 7 , which extend upward and downward below the planes 15 (FIG. 4) of the heat exchanger plates 1 .
  • the extending around the entire opening molding 10a has been pressed at the openings 6 and 7 up out of the plane 15 out.
  • the shaping 10 b provided only around part of the circumference of the openings 6, 7 is directed below the plane 15 .
  • the formations are formed by forming operations in the course of plate making.
  • the formations 10b have flow-directing properties, since they first direct the flow entering the flow channels 5 and 13 into the respective corner region in which the opening 2 or 6 or 7 is located, which can then flow to the associated outlet channel.
  • the mentioned corner areas are of course only available at corners having heat exchanger plates available.
  • the formations 10b cause the medium to not move directly from the inlet channel to the outlet channel, but first spread around the inlet channel, then flow towards the outlet channel where it is also deflected before entering the outlet channel and the plate heat exchanger can leave.
  • Figures 5 and 6 mainly because there was a gap 20 left between the flow-guiding formations 10b .
  • the gap 20 does not cancel the flow-directing property of the formations 10b , but on the contrary, it allows by the possibility of its dimensioning a very targeted division of the flow. In contrast to the illustrations, the gap 20 need not necessarily be formed over the entire area with the same height. A similar effect as by the provision of a gap 20 is achieved by openings or other openings 30 between otherwise adjacent formations 10b , wherein the size or number is selected according to the desired distribution of the flow. (FIGS. 7 and 8) In particular, it can be seen from the detailed illustrations that the formation 10a is formed directly on the edge 11 of the respective opening 2, 6, 7 and the flow-directing formation 10b adjoins it outwardly.
  • the formations 10a, 10b are as close as possible to the edge 11 of the openings.
  • the cross section through the two formations 10a, 10b has an approximately S-shaped configuration, ie they merge into one another.
  • the formation 10a serves to form the respective inlet or outlet channel, since it is connected to an identical formation 10a of the adjacent heat exchanger plate 1.
  • the height of the formations 10 a is approximately half the height of the flow channels 13 .
  • the height h (FIG. 4) of the flow channels 5, 13 could be bridged by formations 10a, 10b present only on a heat exchanger plate 1 , since the adjacent heat exchanger plate 1 has no formations 10a, 10b .
  • this idea is also applicable to plate heat exchangers, which are arranged in a housing, transferable.
