Definitions

  • the present invention relates to a plate heat exchanger according to the preamble of claim 1.
  • a plate evaporator for evaporating a fluid with a Number of superimposed heat transfer plates is off WO 91/16589 known.
  • By corrugated sheet-like training of Heat transfer plates are here between the individual Plate flow spaces are available for the heat exchange media posed.
  • the sweep angle of the individual flow channels to be variable along the length of the plate evaporator.
  • herringbone-like structures trained heat transfer plates for generation of cross-channel structures to be arranged alternately or in opposite directions. That is, they become essentially w-shaped herringbone-like Structures and M-shaped herringbone-like Structuring arranged on top of each other.
  • the sweep angle becomes an angle between the Main flow direction of the heat exchange media and the herringbone pattern Structuring of the heat transfer plates Roger that.
  • the media is fed in and out conventionally through one hole each, which with the corresponding Flow channels of the plate heat exchanger communicate.
  • the alternating arrangement results W-shaped and M-shaped, herringbone-like patterns for both heat exchange media same flow channel volumes (same volumes on the primary and secondary side of the plate heat exchanger).
  • the object of the invention is therefore to create a plate heat exchanger, effective evaporation, in particular while avoiding the Leidenfront phenomenon, is feasible.
  • Plate heat exchangers are the heat transfer plates as sheets with herringbone-like structure formed, whereby to form the primary-side flow channels two each running essentially in the same direction Structures are arranged one above the other, and in opposite directions to form the secondary-side flow channels Structures for creating cross-channel structures to be arranged one above the other.
  • Herringbone shaped Sheets have one according to the invention on both sides usable structuring. When stacked on top of each other in an essentially uniform herringbone pattern Structuring can be two heat transfer plates very close to the formation of very narrow flow channels be brought together, the elevations of one Pattern in the recesses of the other pattern while maintaining intervene at a minimum or desired distance.
  • an opposing arrangement can be arranged one above the other or not herringbone-like herringbone Structuring a flow channel side with relative large volumes are made available, it being here due to the cross-channel structure to a very good heat transfer a heat transfer medium to the heat transfer plates is coming.
  • Plate heat exchanger is or are for at least one of the heat exchange media is one through the heat transfer plates extending, with the primary or inlet duct communicating on the secondary side for the introduction of the heat exchange medium into the plate heat exchanger, and two extending through the heat transfer plates with the primary-side or secondary-side flow channels communicating outlet channels for the output of the heat exchange medium intended.
  • the inlet opening is expediently located at one end of the Plate heat exchanger in the area of its central axis with respect the main direction of flow, the outlet bores symmetrical at the other end of the plate heat exchanger are offset with respect to the central axis.
  • Plate heat exchanger becomes an arrow angle the structuring of the heat transfer plates with respect the central axis of the plate heat exchanger in the main flow direction varies. For example, by reduction of the sweep angle in the flow direction of the heat transfer medium Pressure loss of the heat transfer medium can be minimized. Corresponding applies with decreasing arrow angle in the flow direction of the medium to be evaporated.
  • the primary side and / or a flow coating on the secondary side by means of which the efficiency of the heat exchanger improved by increasing the heat transfer area if the coating has a defined roughness.
  • the coating is a further embodiment of the invention the primary-side and / or secondary-side flow channels doped with a catalyst material, resulting in the heat exchanger a catalytic reaction is made possible.
  • Fig. 1 is a heat transfer plate in a schematic Shown top view.
  • the structuring 10 has surveys and deepening.
  • 1 in the representation of FIG Invisible back of the heat transfer plate 2 has appropriate structuring.
  • the heat transfer plate 2 is formed with a number of bores 4, 5, 6, 7. When stacking a number of heat transfer plates 2 these bores form inlet channels or Outlet channels for the heat exchange media, as described below becomes. It can be seen in Fig. 1 that two Bores 4, 7 on the central axis M of the heat transfer plate are arranged while the remaining bores 5 and 7 are positioned symmetrically with respect to this central axis M.
  • Fig. 2 is a preferred embodiment of an inventive Plate heat exchanger in a schematic side sectional view shown.
  • the heat transfer plates 2 are in here arranged a housing 20 which has a lower part 20a, has an upper part 20b and side walls 20c. It can be seen that due to the stacking of the holes 4 an inlet channel 40 is formed, via which a heat transfer medium insertable into secondary flow channels is, the secondary flow channels in turn with an outlet channel 50 communicating through the stacking the holes 5 is formed.
  • One to be evaporated Medium is formed accordingly via an inlet channel 70 ( by stacking the holes 7) in the primary Flow channels insertable, which in turn with a Output channel 50 communicate, which by stacking the holes 5 arises.
  • the primary and the secondary Flow channels do not communicate with each other.
  • two of inlet channels 70 formed on opposite sides are formed are. It is possible in the same way, only one, with all primary-side flow channels communicating inlet channel 70 to provide. All channels are cylindrical Pipes on which in their side walls with corresponding Openings to create the desired connections are formed with the flow channels.
  • the primary and secondary sides Flow channels with different channel diameters or to form volumes.
  • a primary side Channel structure through which in particular one to be evaporated Heat exchange medium should flow to this Purpose two heat transfer plates, as shown in Fig. 1 are arranged one above the other and fixed to each other, that the respective herringbone-like structures run parallel to one another, the elevations of the a heat transfer plate at least partially in the recesses protrude into the second heat transfer plate, such as is shown schematically in Fig. 3.
  • the superimposed structures are here with 2a, 2b designated. It can be seen in Fig. 3 that between the heat transfer plates or structuring 2a, 2b spacer elements 25 are provided, by means of which a desired or necessary distance between the structures 2a, 2b adjustable is.
  • the spacing elements 25 are schematic also in the upper right area of that shown in Fig. 1 Heat transfer plate 2 shown. Through this interlocking structuring can the heat transfer plates 2a, 2b arranged much closer to each other compared to superimposed herringbone patterns Structures which are opposing or not are parallel to each other.
  • Plate heat exchangers Due to the primary or volume reduction on the evaporator side is conventional Plate heat exchangers have improved dynamics posed.
  • An adjustment of the height of the primary or secondary Channels can be achieved through the spacing elements 25.
  • the heat transfer plates used in the invention are by embossing, for example a sheet metal plate, in simple Way to make.
  • the respective heat exchange media assigned holes or channels 7, 5 and 4, 6 with respect the central axis M of the heat transfer plate 2 is arranged in a Y shape are.
  • the medium to be evaporated occurs, for example via the hole 7 in the plate heat exchanger and leaves it again through the holes 5.
  • the flow of the medium to be evaporated through the plate heat exchanger is therefore essentially Y-shaped, resulting in a symmetrical Temperature distribution within the plate heat exchanger or leads on the heat transfer plates.
  • the thermal or mechanical stress of the heat transfer plates effective against conventional solutions can be reduced.
  • Pressure loss of the heat transfer medium can be avoided by appropriate Training of herringbone-like structures of the secondary channels can be optimized.
  • To this Purposes can be, for example, the surveys or depressions the respective flow channels should be rounded, and not, as is shown schematically in FIG. 3, pointed or angular.
  • the spacer elements 25 also lead to turbulence heat exchange medium flowing through primary-side flow channels, whereby the heat exchange effect of the plate heat exchanger is further improved.
