Definitions

  • the invention relates to a plate heat exchanger according to the preamble of patent claim 1.
  • a plate heat exchanger which has a number of heat exchanger plates stacked on one another and soldered on a rectangular base plate, which are deformed in such a way that they form at least two separate flow channels for heat-exchanging media.
  • the stack of heat exchanger plates is provided with at least one vertical passage opening which is sealed against the flow channels of the media and in which a removable attachment member (for example a screw) is located.
  • the object of the invention is to significantly reduce in a plate heat exchanger of the type mentioned in the production effort in a further simple, space-saving attachment of the plate heat exchanger on said array area ,
  • the base plate has at least two passage recesses for fastening elements at its edge regions, wherein the heat exchanger plates, with the exception of at least two protrusions provided in the region of the passage recesses, are designed to be baseplate-sized.
  • the heat exchanger plates with the exception of at least two protrusions provided in the region of the passage recesses, are designed to be baseplate-sized.
  • the plate heat exchangers according to FIGS. 1 to 6 all comprise a number of heat exchanger plates 2 which are stacked on one another and are connected to one another, for example by soldering, which are formed to form at least two mutually separate flow channels for heat exchanging fluids the plate heat exchanger has means for releasably securing it to an array area.
  • this fastener is formed from a screw 4, which engages from above through a introduced into all heat exchanger plates 2 fürgangsöffnug 12 and with its head on the base plate. 1 supported. Good to see in Figure 6, moreover, the above-mentioned flow channels for the heat-exchanging fluids.
  • the base plate thus has, except for the area where the plate heat exchanger is attached to said arrangement region, for example in a heater by means of screws, substantially the same base area as the heat exchanger plates.
  • the formations 5 are formed in the form of continuous, rounded transitions, d. H. Edged areas, which would also be detrimental to the flow within the heat exchanger, are avoided by this proviso.
  • the inlet, 7 and discharge ports 8, 9 on the base plate 1 are preferably, as shown, formed as simple openings, which are formed in alignment with arranged on the array portion connecting piece 13 with suitable form seals 14 such as O-rings.
  • suitable form seals 14 such as O-rings.
  • the plate heat exchanger shown in Figures 1 to 4 has two different types of für Bachsaus principle 3 by way of example.
  • the für Bachsaus principleung 3 is designed as a rim of the base plate 1 towards the open slot 10 and right as a bore.
  • the base plate 1 has a tab-shaped expression 11 projecting beyond its rectangular basic cross-section in the region of the passage openings 3.
  • This proviso has the advantage that the formations on the heat exchanger plates 2 must be less pronounced than in the Au Replacementsform according to Figures 1 to 4.
