But it is particularly advantageous to save the two connection areas for the passage of the less aggressive medium and to occupy with the less expensive, less corrosion-resistant material.
  • the wall thickness of the higher-grade material occupancy as well as the less high-quality material occupancy should preferably be the same for cost reasons, so that no material offset must be bridged with additional effort to the circumferentially circumferential edge seals the plates.
  • a heat exchanger plate according to the invention is advantageously only in such sub-areas on its front and / or back with the second, especially higher-grade material is occupied, where this is actually required due to a given media contact, so as to achieve the desired cost advantages ,

  • it could be according to the invention occupied on its front side over its entire surface with the higher quality material.
  • the plate area effectively acted upon by the aggressive medium is limited by the conventional seal 13a defining the heat exchanging area, the areas of the plate face not coming into contact with the aggressive medium may be made of the conventional base material , These areas could begin immediately at the seal 13a, such as at the lowest point of the seal groove or externally adjacent.
  • connection areas around the openings 5 and 7 around ie to those openings, which are flowed through by the less aggressive medium and surrounded by the usual seals 5a and 7a, from the lower-cost base material or produce it occupy.

  • FIGS. 4a and 4b show the cross sections AA and BB. You can see in the upper half of FIG. 4a the already designated material transition between highly corrosion-resistant and less corrosion-resistant material, whereas the lower portion of FIG. 4a the conditions at the back of the plate shows where the less high-grade material passes through.
