Definitions

  • the invention relates to a plate heat exchanger consisting essentially of flat heat exchanger plates that have an erected, revolving, outer Have edge and at least four openings and so stacked one inside the other and are connected by soldering that the openings vertical channels through the Plate heat exchangers result and flow channels between the heat exchanger plates are available for different fluids, the circulating Edge of the one heat exchanger plate that closes the stack of heat exchanger plates one different from the edges of the other heat exchanger plates Has a turn.
  • the invention further relates to a production method for the plate heat exchanger.
  • the plate heat exchanger corresponds to DE 196 28 561 C1. 4 and 6 this Document show that the edge of the top heat exchanger plate after is bent inside, while all other edges are uniform and tub-like are directed upwards. This measure often encounters difficulties because Connection piece or other elements belonging to the plate heat exchanger must be placed very close to the edge mentioned.
  • the invention has for its object the plate heat exchanger from To further develop the generic term and to specify a suitable manufacturing process, with which the difficulties mentioned are excluded.
  • the solution according to the invention provides that the edge of the stack of heat exchanger plates final heat exchanger plate over the edge of the one below arranged heat exchanger plate is bent.
  • This measure can be used, for example, for a connection piece directly on Edge can be arranged without encountering difficulties. Further the stability in the edge of the top heat exchanger plate was improved.
  • the heat exchanger plates usually have an extremely small sheet thickness on why the edge of such plate heat exchangers that are not according to the invention are designed, in operation or already during transport to the customer or often damaged during installation, i.e. bent or even torn. Further such edges are extremely sharp, which creates the risk of injury become.
  • the training according to the invention counteracts all this.
  • the edge on the stack of heat exchanger plates final heat exchanger plate before stacking the Heat exchanger plates can be attached by means of a forming tool.
  • This measure has proven to be significantly easier and cheaper than that Known reshaping of the edge on the soldered plate heat exchanger. additionally it was found that this measure deburred the sharp edge will, i.e. can be made less sharp-edged or blunted.
  • the manufacturing method according to the invention provides that the edge of the Stack of the heat exchanger plates concluding the heat exchanger plate in one Forming tool is bent outwards and the heat exchanger plate afterwards is placed on the stack of heat exchanger plates, their edge the Edge of the heat exchanger plate underneath.
  • edges of the heat exchanger plates that form the stack are preferred of the simplest shape, resulting in low tooling and manufacturing costs become. They are simply erected in a simple and tub-like manner and the heat exchanger plates are stacked so that their edges are finished Plate heat exchangers give it a scale-like structure. The final heat exchanger plate has its edge before the bending process the same shape as all other heat exchanger plates.
  • the plate heat exchanger of the exemplary embodiment is provided for the heat exchange between more than two fluids. It therefore has special connection flanges 1; 2; 3, which as a connection adapter 1; 2 are formed, as was described and shown in DE 196 28 561 C1 and also in DE 196 28 560 C1. These details are less important in the present context, but it should be pointed out that in particular the connecting flange 1 is very close to the edge 9 of the plate heat exchanger or the heat exchanger plates 8 ; 13 is arranged, even partially extends beyond this edge 9 , as can also be seen from FIG. 2, top right.
  • the connecting flanges 1, 2, 3 have bores 20 which are used for fastening to the counter flanges (not shown) on a gear or the like.
  • the plate heat exchanger has a base plate 15 which is somewhat reinforced in the sheet thickness, the corners 16 of which are bent upwards and bear against the edge 9 of the lower heat exchanger plates 8 in order to give the stack improved stability.
  • a cover plate 19 lies on top of the uppermost heat exchanger plate 13 .
  • All heat exchanger plates 8; 1 3 each have four circular openings, which after the stacking of the heat exchanger plates 8; 13 channels 4; 5; 6 and 7 result, which serve for the supply and discharge of the fluids.
  • a coolant could be supplied to the channel 5 , which leaves the plate heat exchanger again at the channel 7 after it has flowed through all the flow channels 12 (FIG. 2) and has absorbed the heat of the other fluids.
  • On Channel 4 such a heat-emitting fluid flows in and on channel 6 again after at least some of the flow channels has passed through.
  • 11 Another heat-emitting fluid flows in at channel 17 and out again at channel 18 .
  • the heat exchanger plate 13 which is the uppermost heat exchanger plate in the exemplary embodiment and which otherwise does not differ from the other heat exchanger plates 8 , is processed in a simple forming tool (not shown) around the edge 10 , as shown in FIG. 10 , before it is placed on the stack of heat exchanger plates 8 Fig. 3 shown to reshape. 3, the end 14 of the edge 10 is perpendicular to the plane of the heat exchanger plates 8; 13. In the embodiment shown in FIG. 4, this end 14 was bent further towards the plate heat exchanger, thereby further reducing the risk of injury during handling. After this shaping operation, the heat exchanger plate is placed on the stack as the top heat exchanger plate 13 .
