Definitions

  • the invention relates to a plate heat exchanger with channels flowed through in cocurrent or countercurrent, which are formed for one medium between individual plates each connected to a plate pair and for the other medium between the plate pairs joined to form a plate stack, the individual plates and the plate pairs being parallel to them
  • Main flow direction edges are connected to each other, the inflow and outflow cross sections of each flow channel in the main flow direction are arranged diagonally to each other and the immediately adjacent inflow or outflow cross sections for one medium to the adjacent outflow or inflow cross sections for the other medium by half the height of each Inflow and outflow cross sections are offset.
  • Plate heat exchangers of the type described above with channels flowing through in countercurrent are known from DE-PS 41 00 940. With an extremely compact design, they have a high heat exchanger efficiency and can also be manufactured inexpensively for aggressive media.
  • the invention has for its object to further improve the efficiency of these known plate heat exchangers while reducing their dimensions.
  • the solution to this problem by the invention is characterized in that the individual plates have guide vane-like, at least in the inlet area of each flow channel. Elevations formed by one-sided features of the individual plates and protruding from both sides into the flow channel and the medium entering through the inflow cross-section distributing over the full channel width of the flow channel are provided in the manner of an angle with an inflow leg oriented approximately parallel to the main flow direction and one under one Angle between 7 ° and 90 ° to the main flow direction outflow legs are formed, wherein a defined gap is formed within the flow channels between the opposite guide vane-like elevations.
  • the guide vane-like elevations can protrude into the flow channel from both sides. In this way, the height of the individual surveys and thus their susceptibility to contamination can be reduced.
  • a defined gap is formed within the flow channels between the opposite guide vane-like elevations. The surveys are thus partially overflowed, so that the danger an accumulation of solid particles is significantly reduced.
  • the guide vane-like elevations are formed in the entry area of each individual plate in the manner of an angle with an inflow leg oriented approximately parallel to the main flow direction and an outflow leg lying at an angle between 7 ° and 90 ° to the main flow direction.
  • a further effective support for the equalization of the flow within the flow channel can be achieved in that the flowed ends of the guide vane-like elevations are arranged obliquely to the main flow direction.
  • the guide vane-like elevations are preferably arranged closer to the inlet cross section in the longitudinal center of the individual plates than the elevations arranged at the edge of the individual plates.
  • the guide vane-like elevations in the outlet area of each individual plate are mirror images of the guide vane-like elevations in the inflow area.
  • a particularly simple and inexpensive type of guide vane-like elevations can be created according to the invention in that the guide vane-like elevations are formed by one-sided features of the individual plates.
  • each individual plate is provided, according to a further feature of the invention, with profiling which adjoins the inlet area and runs across the entire channel width and channel length and generates turbulence .
  • the heat transfer is increased by the turbulent flow and thus the efficiency of the plate heat exchanger according to the invention is increased.
  • these profiles are created in that each individual plate is provided with knobs which are alternately pronounced on one of the two sides.
  • knobs can be designed according to the invention as spacers for adjacent individual plates. Such spacers can finally also be formed in the area of the guide vane-like elevations in order to keep the individual plates at a predetermined distance from one another in the entry and exit area.
  • FIG. 1 The embodiment of a plate heat exchanger shown schematically in FIG. 1 shows in perspective a plate stack S composed of a plurality of shaped individual plates 1, which are each connected to one another to form a plate pair P.
  • Each individual plate 1 comprises a floor 11 which lies in a different plane than the longitudinal edges 12. Following and parallel to these longitudinal edges 12, each individual plate 1 is each formed with a contact surface 13 which is offset in height from the longitudinal edges 12. The offset between the contact surface 13 and the associated longitudinal edge 12 is twice as large as the offset between the longitudinal edges 12 and the bottom 11. The bottom 11 is therefore located in the middle between the plane of the longitudinal edges 12 and the plane of the contact surfaces 13.
  • transverse edges 14a and 14b are obtained, which in the Height, ie perpendicular to the surface of the floor 11 are offset from one another by the same amount as the planes in which the longitudinal edges 12 on the one hand and the contact surfaces 13 on the other hand. 1 clearly shows that the transverse edges 14a and 14b are diagonally opposite one another.
  • FIG. 1 shows five complete plate pairs P, a single plate 1 being arranged on the uppermost plate pair, which is also connected to the plate plate P shown at a distance from the uppermost single plate 1.
  • Fig. 1 which shows a counterflow heat exchanger, shows that due to the diagonal arrangement of the inlet and outlet openings, the inflow cross sections Z1 and Z2 for the one medium next to the outflow cross sections A2 or A1 for the other medium, each offset by half a height of a pair of plates P.
  • inflow cross section Z 1 or Z 2 extends only over half the width of the flow channel within an axial entry area E as short as possible over the full width of the channel cross section
  • guide vane-like elevations 2 which protrude into the flow channel and distribute the medium entering through the inflow cross section Z1 or Z2 to the full channel width of the flow channel.
  • the guide vane-like elevations are designed in the manner of an angle with an inflow leg 21 oriented approximately parallel to the main flow direction and an outflow leg 22 lying at an angle between 7 ° and 90 ° to the main flow direction.
  • the elevations 2 formed in the middle of the single plate 1 can preferably be designed with elongated outflow legs 22. It is also advantageous if the flowed ends of the elevations 2 are arranged obliquely to the main flow direction, the guide vane-like elevations 2 in the longitudinal center of the individual plate 1 being arranged closer to the inflow cross section than the elevations 2 arranged on the edge of the individual plates 1.
  • the guide vane-like elevations 2 are formed on one side by the individual plates 1 formed, the elevations 2 shown in dashed lines in the lower part of the illustration protrude into the respective other flow channel delimited by the same single plate 1. In this way, guide vane-like elevations 2 projecting from both sides into the respective flow channel, a defined gap being formed between these opposing elevations 2, which allows the elevations 2 to flow partially over them, thereby preventing clogging of the inlet areas E in the case of media loaded with solid particles becomes.
  • each individual plate 1 is provided with a knob field from a multiplicity of in individual knobs 31, 32 protruding into the flow channel. These individual knobs 31, 32 are alternately formed on one of the two sides of the single plate 1.
  • the individual knobs 31 recognizable in the plan view according to FIG. 2 are each represented by a circle, the individual knobs 32 formed on the opposite side by a cross.
  • the pimple field formed by the individual pimples 31 and 32 in the two adjacent flow channels creates a turbulent flow over the full length and width of the flow channels by means of the profiles produced thereby, which increases the heat exchange performance of the plate heat exchanger.
  • knobs 31 and 32 can be designed as spacers for adjacent individual plates 1. Spacers of this type can also be formed in the region of the guide vane-like elevations 2, which are indicated by circles in FIG. 2.
  • FIG. 3 shows a single plate 1 for a heat exchanger, the channels of which are flowed through in the direct current of the two media. Accordingly, the guide vane-like elevations 2, which are pronounced on one side, are formed in mirror image of the elevations 2, which are pronounced on the other side.
  • One medium is here represented by arrows with solid lines, the other medium is symbolized by arrows which are shown in broken lines.
