Definitions

  • the invention relates to a plate heat exchanger with a plurality of profiled, substantially rectangular plates with inlet and outlet openings in the corner areas, which are arranged in a stack such that flow spaces between the plates can be alternately fed with a first and a heat-exchanging second medium, the Plates are welded together and sealed from the environment.
  • Welded plate heat exchangers have the advantage over heat exchangers with detachable plates that the elastic seals between the plates can be dispensed with. Therefore, welded plate heat exchangers can be operated at higher temperatures and pressures as well as with more aggressive media than heat exchangers with seals. In addition, there is no fear of malfunctions due to leaking seals that need to be replaced.
  • Welded plate heat exchangers are known from the English patent applications 2 126 703 and 2 167 175, in which the spacing and welding of adjacent plates is carried out using separate metal sealing strips. These sealing strips are made according to the desired flow application is welded onto the one plate, then the neighboring plate is aligned accordingly and in turn welded onto these metal strips. With regard to the latter welding process, it is necessary to weld through the upper plate. So that there is no damage to the previously made welded connection, the sealing strips must be staggered relative to one another in successive flow spaces. All of this leads to very high manufacturing costs for these plate heat exchangers.
  • the present invention is therefore based on the object of specifying a plate heat exchanger in which all of the plates are welded to one another, but which is distinguished from the prior art by much less expensive production.
  • the plates are angled several times along their outer circumference, so that they have a staggered first peripheral region parallel to the plate, which is aligned with one apex of the plate profiling and a second staggered peripheral region parallel to this, with aligned with the other apex of the plate profiling, that the inlet and outlet openings of each plate for the one medium have annular surfaces which are approximately - preferably exactly - offset from one apex plane, while the inlet and outlet openings for the other medium have annular surfaces which about - preferably exactly - are offset from the other apex plane, and that two adjacent ones Plates are welded continuously along the adjoining first edge regions and along the ring surfaces or adjoining bends to form a cassette, while adjacent cassettes are welded continuously along the adjoining second edge regions and along the ring surfaces or adjoining turns.
  • the design according to the invention has the advantage that all plates can be shaped identically, so that only one type of stamp is necessary for the entire heat exchanger. To produce the cassettes, the plates only need to be rotated 180 ° against each other so that they come to lie back to back in pairs.
  • the ring surfaces on one side of the plate longitudinal axis are offset opposite to the ring surfaces on the other side of the plate longitudinal axis.
  • the plates then have to be rotated about their transverse axis and the media flow predominantly in the counterflow direction.
  • edge areas as well as the ring surface of each plate are flat so that a problem-free, tight weld is guaranteed.
  • a particularly advantageous embodiment of the invention consists in that the bends adjoining the ring surfaces are arranged approximately perpendicularly thereto and that these bends are alternately directed so that the plates which form a common cassette each have bends which can be plugged together.
  • the panels of a cassette no longer need to be welded within the panel hole, but from the top of the panel, which is more accessible and visible. The welding is therefore easier and at the same time more reliable.
  • bends of two plates to be put together are of unequal length, in such a way that the free edges of the bends are aligned when plugged together. This makes welding even easier.
  • each plate has a large and slightly less protruding bend at the top and the same at the bottom.
  • the first edge region, along which the plates are welded to form a cassette, is expediently through an intermediate piece running perpendicular to the plate plane is connected to the second edge area, along which the cassettes are welded together.
  • the edge areas immediately follow one another on the outside and a compact structure of the plate is obtained.
  • the heat exchanger plates 1 of both designs have in common that they each have an opening 2 at their four corners have for the inlet and outlet of the heat-exchanging media and that the field between these openings is profiled with waves 8.
  • These shafts 8 are arranged symmetrically with respect to the plate plane, that is to say they protrude by the same amount on both sides.
  • both designs have in common that the plates are surrounded by a first edge region 3, this edge region being offset from one apex plane of the shafts 8, at least as far as the shafts 8 protrude.
  • Two of the four openings 2 are offset by the same amount in one apex plane of the shafts 8 and the other two openings in the other apex plane of the shafts 8.
  • the openings 2 are each surrounded by an annular surface 5 and 9, which join this offset.
  • the two openings arranged in the left half of the plate, of which only the upper one is visible, are offset with their ring surfaces 9 as well as the first edge region 3, whereas the two openings arranged in the right half of the plate , of which only the upper one is also visible, are offset with their ring area 5 to the rear.
  • an approximately cylindrical bend 5a and 9a adjoins the inner edge of the ring surfaces 5 and 9, respectively.
  • the size and direction of these bends are chosen so that in the case of two plates with which a cassette is to be formed, the bends at the openings 2 or 3 which are not Should have passage to the plate gap, are slidably to be inserted into each other and that then the free edges of the bends are aligned with each other when plugged together. This allows these bends to be welded easily and reliably from the top of the plate.
  • a second edge region 4 adjoins the inner edge region 3 via an intermediate piece that runs perpendicular to the plate plane, but which runs in the opposite apex plane to the edge region 3.
  • FIGS 3 and 4 show sections through the plate pack according to Figure 1, but the plates have no bends 5a and 9a.
  • the welding at the inlet and outlet openings is carried out along the ring surfaces 5 and 9, which are adjacent to one another in pairs.
  • the other plate design according to FIGS. 1a to 4a differs in that the second edge region 4 is dispensed with, that is to say the plates run out with the first edge region 3 and that adjacent cassettes are connected by interposed U-profiles 10, cf. Figure 1a.
  • These U-profiles 10 are dimensioned such that they fit flush into the space between the edge areas 3 of adjacent cassettes, so that their legs can easily be welded to these edge areas.
  • the plates do not need to be welded together individually, but there is the advantageous possibility of stacking the plates and U profiles and to weld together two panels that form a cassette and two U-profiles on both sides in a single operation.
  • the plate heat exchanger is assembled in such a way that two plates belonging together are placed one on top of the other, so that, for example, the bends 5a are inserted into one another, so that the bends 5a are then welded together at both openings, and then a U-profile frame 10 and the third heat exchanger plate is placed so that their bends 9a are mated with the corresponding bends 9a of the second plate and then the bends 9a are welded together.
  • This process is repeated with the placement of the fourth plate, which in turn is inserted and welded with the bends 5a.
