Definitions

  • the present invention relates to a turbulence plate for a heat exchanger according to the preamble of claim 1.
  • Turbulence sheets for heat exchangers often have a corrugated, in particular a surface-enlarging structure.
  • the enlarged surface is intended to allow improved heat exchange, that is, improved heat transfer.
  • the example corrugated shape of such turbulence sheets is usually produced by means of a rolling process in which a sheet passes between two profiled rolls and is formed during passage through the profiling of the two rolls.
  • Another common method for producing such turbulence sheets is embossing by means of a so-called Monost Zis, which is pressed into an associated matrix. Due to the formation of the monostrand, however, only one corrugation peak or one corrugation valley is introduced into the turbulence sheet to be formed or produced per stamping process, so that such a production method is time-consuming and expensive.
  • the present invention is concerned with the problem, for a turbulence sheet of the generic type, to provide an improved embodiment, which in particular allows a cost-effective production of such turbulence sheets.
  • the invention is based on the general idea, no longer produce a turbulence plate for a heat exchanger by means of a Monostempels or a rolling process, but rather by means of a usual from the automotive industry thermoforming process, wherein in a single deep drawing a plurality of parallel juxtaposed wave troughs and wave crests in the umzuformende Turbulence sheet can be introduced so that they can be produced faster and more cost-effective in particular by the deep drawing of the invention the turbulence plates.
  • the term "drawing" means the forming of a sheet metal blank by means of tensile pressure, whereby a hollow body is formed, which is open on one side.
  • the turbulence sheets can be produced particularly economically by means of such deep drawing.
  • the turbulence plate from a plane of the same punched out and shaped webs on.
  • These webs are arranged in their entirety in the manner of parallel offset wave troughs and peaks and serve on the one hand to stiffen the turbulence plate and on the other hand to improve the heat transfer.
  • the webs can be both punched in a single step and then also shaped.
  • corresponding cutting and forming contours are provided on a corresponding deep-drawing tool or on a die and a punch of the same.
  • turbulence plate 1 is used, for example, in a heat exchanger in order to produce the largest possible surface area for optimum heat transfer, that is to say optimal heat exchange and optimum turbulence of the fluid.
  • turbulence sheets 1 were previously deformed by means of two mutually-running and profiled rolls or by means of a so-called Monost Zis, which has ever stamped a wave crest 5 or a wave trough 6 in the still undeformed turbulence sheet 1.
  • a deep-drawing tool 2 with a punch 3 and an associated die 4 is used, wherein a plurality of wave crests 5 and wave troughs 6 are arranged next to one another in the die 3 or in the die 4.
  • cutting edges may be provided in the deep-drawing tool 2 according to the invention, which in the deep-drawing process from a plane of the turbulence sheet 1 punched out and shaped webs 7 (see. Fig. 5 ) produce. These webs 7 increase the turbulence of a flowing fluid and thereby ensure a particularly good mixing of the fluid.
  • the turbulence plate 1 has a rectangular-wavy structure with mutually parallel wave crests 5 and troughs 6, wherein the entirety of the webs 7 can be considered as parallel to the actual wave crest 5 shifted wave crest 5 '.
  • the turbulence sheet 1 is transported as a band plate 8 from a roll to a pressing tool 9 and there between two rollers 10,10 'tapers in terms of its thickness and / or already preformed. It is conceivable here that by means of the pressing tool 9, the wave crests 5 and / or the wave troughs 6 are at least preformed. In particular, in this rolling process also lateral strips 11, 11 'with Positioning openings 12, 12 'are generated, which allow better positioning and fixing of the turbulence sheet 1 in the deep-drawing tool 2.
  • the turbulence sheet 1 is cut off by means arranged on the punch 3 and / or on the die 4 of the thermoforming tool 2 cutting edges. With the thermoforming tool 2 while the turbulence plate 1 is deformed into its final shape (final shape).
  • turbulence sheets 1 for heat exchangers can be produced inexpensively and quickly, whereby an economic production of such turbulence sheets 1, combined with low unit costs, can be realized.
