Definitions

  • the invention relates to a plate heat exchanger with channels through which a cross flow flows, which are formed for the medium in a wave shape between individual plates each connected to a plate pair and for the other medium in a tube form between the plate pairs joined to form a plate stack, the individual plates having a plurality of parallel rows of in the flow direction of a medium-running, channel-shaped embossing sections are provided and the individual plates are connected to one another at their edges extending transversely to the channel-shaped embossing sections to form pairs of plates and the plate pairs are connected to a stack of plates at the respective other edges of the individual plates.
  • Such plate heat exchangers are known. Since the trough-shaped embossing sections run parallel next to one another over the entire surface of the individual plate, rectangular support fields result over the entire length or over the entire width of the individual plates if the plates of the plate stack also coincide due to a pressure difference between the two media participating in the heat transfer Pressure. While the support field width of the corrugated channels running between individual plates connected to a pair of plates corresponds to the center distance between the rows of parallel trough-shaped embossed sections and is therefore relatively small, support field widths result for the tubular channels that are formed between adjacent plate pairs correspond to the length of the groove-shaped embossing sections.
  • the invention has for its object to avoid the risk of such permanent deformation due to insufficient support of the individual plates against each other and to further develop a plate heat exchanger of the type described in the introduction by simple structural measures such that its individual plates are not subjected to unduly high deformation forces even with larger pressure differences.
  • the solution to this problem by the invention is characterized in that the groove-shaped embossing sections of adjacent rows are offset from one another in the longitudinal direction.
  • each individual plate with at least one characteristic formed between adjacent rows of channel-shaped embossed sections, and this is also reduced to zero and, as a result, the flow cross-section of the wave-shaped channels is reduced to zero.
  • each individual plate can be formed with at least one corresponding elevation and depression in the region of the groove-shaped embossing sections. These ridges and depressions interlock when plate pairs are joined to form the plate stack and in this way prevent the plate pairs from slipping transversely to the longitudinal direction of the channel-shaped embossed sections.
  • the plate heat exchanger shown in FIG. 1 on the basis of a plate stack formed by five plate pairs consists of identical individual plates 1, each of which is connected in mirror image to one another to form a plate pair P. This connection takes place at the longitudinal edges 1a of the individual plates 1, with a wave-shaped channel K 1 for the medium 1 participating in the heat exchange resulting between the individual plates 1 forming a pair of plates P. This undulating course of the channel K 1 can be seen in the sectional view of FIGS. 2 and 4.
  • tubular channels K 2 for the other medium 2 participating in the heat exchange, which is guided in cross flow to the medium 1.
  • the flow cross section of this rectilinear, tubular channels K2 can also be seen in FIGS. 2 and 4. 1 shows that the individual plates 1 connected to plate pairs P are connected to one another at their edges 1b running transversely to the longitudinal edges 1a to form the plate stack S.
  • each individual plate 1 is provided with a plurality of parallel rows of channel-shaped embossing sections 2 running in the direction of flow of the medium 2, which can also be seen in the top view in FIG. 3 are.
  • These embossed sections 2 of adjacent rows are offset from one another in the longitudinal direction. This results in flat supports 3 between adjacent individual plates 1 between embossing sections 2 which follow one another and which are symbolized in FIG. 3 by dots.
  • These supports 3 form diamond-shaped, uniformly distributed support fields 4 of small dimensions over the entire surface of the individual plates 1, so that even with a higher overpressure in the tubular channels K2 a reliable support of adjacent individual plates 1 is achieved and even at high differential pressures no permanent deformations of the individual plates 1 are to be feared.
  • a strip-shaped support field 5 is further characterized, which results in a load on the individual plates 1 by overpressing in the wavy channels K1.
  • the small width of these strip-shaped support fields 5 shows that even with an overpressure in the wave-shaped channels K 1 no unacceptably high deformation of the individual plates 1 is to be feared.
  • each individual plate 1 is in the embodiment according to FIGS. 1 and 2 with one between adjacent rows of channel-shaped embossing sections 2 trained expression 6 provided.
  • these forms 6 each come into a space between the channel-shaped embossed sections 2 of adjacent rows.
  • each individual plate 1 is provided with at least one elevation 7 in the region of a groove-shaped embossing section 2, which interacts with a corresponding depression 8 when the individual plates 1 of adjacent plate pairs P touching one another are joined, as shown in FIG. 4.
  • This engagement of the corresponding elevations 7 and depressions 8 in the region of the trough-shaped embossing sections 2 likewise results in a positive connection of these individual plates 1, so that slipping of the plate pairs P transverse to the longitudinal direction of the trough-shaped embossing sections 2 is prevented.
