Definitions

  • the invention relates to a plate heat exchanger according to the preamble of claim 1.
  • the seals are glued into embossed circumferential grooves or grooves in a complex manner. Replacing the seals is particularly problematic, for which purpose the plate heat exchangers often have to be sent back to the manufacturer.
  • the object of the present invention is to design a plate heat exchanger of the type mentioned at the outset in such a way that a more secure fastening of the seal in a simple groove can be achieved with simpler means.
  • the invention proposes as a solution to provide in the outer region of the heat transfer plates between the groove and the edge of the plate a plurality of spaced, punched out of the plate material on three sides, upright and inclined tongues that press the elastic seal against the opposite groove wall and the groove base. As a result, a secure fit of the seal in the groove can be achieved in a simple manner.
  • the raised and possibly tongue-inclined tongue can engage in a slot formed in the seal, the length and / or width of which is made smaller than the corresponding length and / or width of the tongue. Due to the elastic deformation of the seal when the tongue is pressed into the slot, the slot wall presses firmly against the tongue. The resulting frictional adhesion between the tongue and the sealing slot alone ensures that the seal sits securely in the groove; the additional clamping effect, if any, due to the inclination of the tongue in the direction of the groove, enables an even better fit of the seal in the groove.
  • the tongues are deformed, for example they are of a crescent shape.
  • the deformation of the tongue increases its strength and the frictional adhesion between the tongue and the sealing slot.
  • the drawing shows a heat transfer plate 6 of a plate heat exchanger in the region of a circumferential seal 2, which is not shown in FIGS. 3 and 4.
  • a circumferential groove 3 is formed by stamping.
  • a plurality of tongues 1 which are punched out on three sides from the plate material and are inclined and deformed toward the groove, are arranged along the groove.
  • the tongue 1 inclined towards the groove presses against the sealing material and thus presses the seal 2 firmly against the groove base 7 and the opposite groove wall 8 and into the groove corner 4, cf. Fig. 1.
  • the seal 2 can, as shown in FIGS. 1 and 2 of the drawing, be provided with a slot 5 in which the tongue 1 engages.
  • the length and / or the width of the slot 5 is made smaller than the corresponding length or width of the tongue 1.
  • the clamping effect produced is further improved while at the same time increased frictional adhesion between the tongue 1 and the sealing slot 5.
  • the strength of the tongue 1 against bending due to the deformation is increased.
