  • the plate packs 2, 2a, 2x of each plate stack 40-40x are uniformly offset horizontally and in this case by separating plates 39; 39a separated.
  • the plate interspaces 11 of the plate packs 2, 2a are connected on the inlet side via separately guided connecting pieces 35, 35a to a distributor 34 which is arranged on the casing plate 21 on the casing side and which is directly in communication with the plate interspace 11 of the plate packet 2x.
  • the plate interspace 11 of the plate package 2 x exit side and the plate interstices 11 of the plate packages 2, 2 a on the outlet side via separately guided connection piece 35 b, 35 x connected to a shell side on the arranged on the housing plate 22 collector 36.
  • the outlet nozzle 14 is fixed in a gas-tight manner, via which a medium supplied on the shell side together to the compact plate heat exchanger and is discharged.
  • the plate interspaces 10 of the plate packs 2, 2 a, 2 x of each plate stack 40 - 40x are flowed through the end face arranged inlet and outlet nozzle together from the second medium end face depending on the connection of Kompaktplattenkorübertragers in countercurrent or direct current.
  • the juxtaposed plate stacks 40 - 40x are separated by partitions 38, 38x having a length approximately equal to the length of an offset plate packet 2, 2a, 2x.
  • the upper and lower housing plates 21, 22 and the two parallel side parts 23, 23a also have a dimension in which the plate stacks 40-40x and the plate packs 2, 2a, 2x of the plate stacks 40-40x with the filling material 29, 29a in and are metallically sealed with the strained housing 1 and in the housing 1 on both sides a free space is guaranteed, that on the one hand during flow of the end face 12 of the plate packs 2, 2a, 2x the plate stack 40 - 40x a preferred flow to the gap 10 is excluded and on the other hand obstruction-free outflow from the plate interspaces 10 of the plate packs 2, 2a, 2x of the plate stacks 40 - 40 is ensured.
  • the plate interstices 11 of the plate packs 2, 2a, 2x of a plate stack 40-40x can be subjected to different media.
  • the separately guided inlet-side connecting pieces 35, 35a and the outlet-side connecting pieces 35b, 35x are not connected to the distributor 24 or to the collector 36, but the connecting pieces 35, 35a are directly connected to a separate inlet socket 13 or connecting piece 35b, 35x connected, which are connected to a separate outlet nozzle 14.
