Definitions

  • a double sheet insert 30 is placed into each of the channels 3. just behind the cover bar 13 at the core 1 cold inlet side. Both sheets 31 of the insert 30 are of the same shape and they are held spaced and in a position which is parallel to plates 10 by conventional means.
  • Fig. 16 presents pins 32 which are welded to the sheets 31.
  • the open holes 14 of the cover bar 13 are conically shaped as a convergent nozzle. This shape increases the velocity of incomming flow delivering a relatively strong jet stream at the entrance into the channel 3.
  • the end boards 18 are from one side exposed to a flow of one of the heat-exchanging media, on the other side they are in a contact with a heat insulation. Therefore the end boards 18 are exposed to more severe thermal gradients than the plates 10. While plates 10 inside the core 1 are free to expand. end boards 18 connected to corner structural elements 19 are restricted in their ability to accomodate thermal expansion forces To overcome this feature stress breakers are built in the core 1 end boards 18 Within the flat surface of the end boards 18 there are implemented diagonally directed cuts 30. which are bridged by hollow ribs 31. as shown in Figs 12, 13 The ribs 31 allow for absorption of any irregularity of thermal expansion of the end boards 18 Besides this one other similar solutions may be utilised.
