  • the edge is at least partially formed by an integrally formed with the base plate and bent along along folding lines extension.
  • a plate heat exchanger having a base plate and heat exchanger plates stacked thereon is known.
  • the base plate projects beyond the heat exchanger plate at the edge.
  • the base plate also has an erected in the direction of the heat exchanger plate stack edge, which follows at least in sections an outline of the heat exchanger plate stack.
  • the DE 10 2009 041 524 A1 discloses a plate heat exchanger having a cover plate, a base plate and interposed stacked heat exchanger plates, wherein the base plate projects beyond the adjacent heat exchanger plate edge and has a set up in the direction of the heat exchanger plate stack edge, which at least partially follows an outline of the heat exchanger plate stack.
  • the edge is formed by an integrally formed with the base plate and bent along along fold lines extension.
  • the JP 2000-310497 A shows as well as the EP 1 241 427 A1 a plate heat exchanger.
  • the WO 2007/038871 discloses a plate heat exchanger having a base plate and stacked heat exchanger plates, wherein the base plate projects beyond the adjacent heat exchanger plate edge.
  • plate heat exchangers are, for example, from the EP 0 623 7987 A2 as well as from the DE 10 2006 005 106 A1 known.
  • the present invention is concerned with the problem of providing for a generic plate heat exchanger, an improved or at least one alternative embodiment, which is characterized in particular by high quality and a simplified and thus cost manufacturability.
  • the present invention is based on the general idea, in a known from the prior art plate heat exchanger with a cover plate, a base plate and interposed stacked heat exchanger plates to form the base plate from a cost sheet metal part and not known from the prior art, as is known from a metal plate up to 5 mm thick.
  • the base plate according to the invention projects beyond the adjacent heat exchanger plates arranged on the edge and also has an erected in the direction of the heat exchanger plate stack edge, which at least partially follows an outline of the heat exchanger plate stack and thereby fixes this with respect to its position on the base plate. According to the invention, this edge is now at least partially formed by an integrally formed with the base plate and bent along fold lines section.
  • the base plate is first punched out as a flat sheet metal part, which then in subsequent bending advances corresponding (sheet) extensions along bent predefined fold lines and thereby the erected edge is formed.
  • the bent projections create double layers, in particular in the respective edge regions, as a result of which the rigidity of the base plate is increased.
  • the base plate according to the invention has a significantly lower overall weight than previously known from the prior art and made of a metal plate base plates.
  • the manufacture of the base plate according to the invention is particularly simple and at the same time inexpensive due to their structural feature. Of course, additionally required through holes of the base plate can be used simultaneously with the punching of the same, for example. a sheet metal are punched out with.
  • the base plate essentially consists of a sheet metal blank which integrally adjoins edge-parallel folding lines (sheet) extensions, which turned double-edged (sheet) areas in the direction of the heat exchanger plates and their falzlinienferne edges bent relative to the plane of the blank and cut to a adjacent edge of the heat exchanger plates are nestled.
  • the base plate made of sheet metal or light metal, in particular aluminum, formed.
  • the design of light metal, especially aluminum another weight advantage can be achieved, which already made of normal sheet metal according to the invention base plate compared to known from the prior art and formed from a thick metal plate base plate significantly less material and thus significantly less Has weight.
  • the material savings with regard to the constantly increasing raw materials also offers an advantage that should not be underestimated.
  • the base plate according to the invention can be produced by means of conventionally known punching and forming machines quickly, with high quality and at the same time inexpensively.
  • the bent sheet metal extensions not only fix the heat exchanger plate stack in terms of its position with respect to the base plate, but also stiffen the base plate, in particular because the fold lines and doubled in this area sheet metal sections allow high stiffness.
  • the erected edge produced from the bent sheet-metal projections does not encompass corner regions of the heat exchanger plates.
  • the edge thus produced is thus only on longitudinal or transverse edges of the heat exchanger plate stack, whereas, however, the corner areas remain free.
  • the edges on the longitudinal or transverse side of the heat exchanger plate stack have a length that is virtually identical to the length or width of the respective heat exchanger plate, so that the corner area that is actually not enclosed turns out to be comparatively small.
  • the base plate 3 projects beyond the adjacent heat exchanger plate 4 at the edge and also has an erected in the direction of the heat exchanger plate stack edge 5, which is at least the nearest heat exchanger plate 4 at least partially, here completely bordered edge and thereby fixed in position relative to the base plate 3.
  • the plate heat exchanger 1 for example, attached to an internal combustion engine.
  • the edge 5 at least partially formed by an integrally formed with the base plate 3 and by along fold lines 6a to 6d bent extension 7, in particular a sheet metal extension 7.
  • the base plate 3 may, for example, from sheet metal or light metal, in particular aluminum, be formed.
  • the base plate 3 is also formed essentially of a sheet metal blank, which has integrally adjacent sheet metal extensions 7 on the edge-parallel fold lines 6a to 6d, 8 folded over the formation of doubled sheet metal areas in the direction of the heat exchanger plates 4 and their falzlinienferne edges 9 bent relative to the plane of the sheet metal blank and are nestled against an adjacent edge of the heat exchanger plates 4.
  • sheet metal blank can be understood a blank of a strip material.
  • the base plate 3 of the invention Due to the inventive design of the base plate 3 as Blechstanz- / molding this can not only cost and relatively simple but also with an increased rigidity, due to the doubled sheet metal areas 8 finished. Compared to previously known from the prior art base plates, however, the base plate 3 of the invention has a significantly lower weight, since the material thickness and the amount of material used can be significantly reduced. Looking at the Fig. 2 , it can be seen that the base plate 3 has a central region 10, on whose longitudinal sides projections 7 are arranged.
  • waste produced in the blanking of the base plate 3 can be reused and returned to the manufacturing process, that is, recycled.
  • the extensions 7 in the base plate 3 according to the Fig. 3 only in a central portion of the respective fold line 6a to 6d integrally connected to the central region 10 of the base plate 3, wherein on both sides of this connection region to the respective fold line 6a to 6d symmetrical cuts 12 between the respective extension 7 and the central region 10 of the base plate 3 are provided.
  • the extension 7 bent over the fold line 6b is at the same time shown in its non-bent position, ie aligned with the central region 10, with an interrupted drawn line.
  • the remaining extensions 7 are made in a similar manner by simply bending around the respective folding lines and the subsequent setting up of the edge 9.
  • Fig. 4 shows a base plate 3, which is substantially that of Fig. 3 corresponds, wherein the extensions 7 account for the shorter transverse sides.
  • the extensions 7 account for the shorter transverse sides.
  • Fig. 5 on the transverse sides of the central region 10 by means of lying arranged and raised sheet metal pieces doubled mounting areas with corresponding edges 9 can be provided. These are then connected to the base plate 3, for example. Soldered.
  • the according to the Fig. 3 to 5 shown base plates 3 have in plan view the shape of an ellipse-like elongated dodecagon. All according to the Fig. 2 to 5 shown embodiments of the base plate 3 is common that these corner regions of the heat exchanger plate stack do not border with the edges 9.
