  • central is to be seen as the geometric centre where the hole is substantially circular or substantially elliptic, or as the centre of gravity of the through hole where the through hole is asymmetric.
  • Figs 9a-9c schematically illustrate a mounting flange 2', which is adapted for use with the heat exchanger as disclosed herein.
  • the mounting flange presents a port hole 21 extending through the mounting flange 2' for introduction or extraction of the heat emitting medium, or cooling medium, where applicable.
  • the mounting flange 2' also presents one or more recesses 23a, 23b, 23c, 23d, 23e, 23f, 23g, 23h, which are adapted for receiving a protrusion, which is formed in the heat exchanger plate, in the area covered by the mounting flange 2'.
  • the mounting flange may further comprise one or more fastening holes 22.
  • the mounting flange may be formed of a single plate, wherein the recesses are formed as recesses, which may be provided as blind holes or through holes.
  • the mounting flange 2' is formed of two separate material plates 24, 25, where a first material plate 24 may be formed with only port hole 21 and fastening holes 22, whereas the other plate is formed also with through holes forming the recesses 23a, 23b, 23c, 23d, 23e, 23f, 23g, 23h.
  • the material plates forming the mounting flange 2' may be of different materials. For example, one of the materials, e.g. the first plate 24, may be selected for optimum strength, while the other, e.g. the second plate 25, may be selected to fit with the brazing process.
