Definitions

  • a plurality of identical heat exchange plates have respective heat exchange surfaces provided with protuberances acting as turbulence-effecting and spacing means between adjacent plates, such plates being adapted for assembly with marginal gaskets to form plate interspaces for throughflow of two heat exchange media along said surfaces at opposite sides (faces), respectively, of each plate.
  • the plate interspaces are of the same depth, and at least one plate is turned 180 relative to the other plates around an axis extending in the plane of the turned plate, the protuberances of each plate being arranged unsymmetrically and so disposed that two different kinds of plate interspaces are formed by such turning of said one plate, thereby creating different flow conditions for the heat exchange media.
  • the present invention relates to a plate heat exchanger comprising identical heat exchange plates which on their heat exchanging surfaces have several protuberances acting as turbulence-effecting and spacing means between the plates, when the latter are assembled with marginal gaskets to form plate interspaces for the throughflow of two heat exchanging media, the interspaces being of the same depth.
  • the plate heat exchanger according to the invention is characterized in that at least one of the heat exchange plates is turned 180 relative to the other plates around an axis extending in the plane of the plate, the turbulence-effecting protuberances of each plate being unsymmetrically shaped and/or located so that two different kinds of plate interspaces are formed by this turning of one plate, thereby creating different flow conditions for the heat exchanging media.
  • Deeper plate interspaces may be provided in a plate heat exchanger either by using thicker gaskets than normally or by using heat exchange plates of which the entire heat exchanging portions are displaced somewhat relative to the respective surrounding marginal portions, in the direction perpendicular to the planes of the plates. In both cases, however, the mutual support is lost between plates forming such deeper interspaces.
  • This support when the distance between the plates is normal, is provided at many points uniformly distributed over the heat exchanging portions of the plates by the usual turbulence-effecting protuberances, such as ridges or the like, in the heat exchanging surfaces.
  • FIG. 1 is a schematic plan view of one kind of plate
  • FIG. 2 is a fragmentary plan view of a modified embodiment of the plate shown in FIG. 1;
  • FIG. 3 is a view similar to FIG. 1 but showing another kind of plate
  • FIG. 4 is a fragmentary cross-sectional view of another plate.
  • FIG. 5 is a fragmentary crosssectional view on the center line 6 in FIG. 1, as viewed from the right.
  • the plates shown in the drawing have the usual holes 1 for passage of the heat exchanging media and are provided at their ends with notches 2 and 3 acting as guiding means when a number of plates are to be assembled in a pack in a plate heat exchanger frame (not shown).
  • the conventional edge or marginal gaskets extending around the heat exchanging surfaces and the holes 1 are omitted, as they do not form any part of this invention. It will be understood that such gaskets are provided in the conventional manner between adjacent plates in the pack so that the two heat exchange media are directed through corresponding holes 1 to their respective plate interspaces, where they flow at opposite sides (faces) of each plate along its heat exchanging surfaces surrounded by the gaskets.
  • These heat exchanging surfaces are corrugated to form ridges and valleys on each side of each plate, such corrugations being formed in the fabrication of the plates and serving to effect turbulence of the heat exchange media flowing through the heat exchanger in the passages between the assembled plates.
  • the full lines 4 and 5 represent the ridges constituting the tops of the protuberances formed by the corrugations.
  • the ridges 4 extend parallel to each other but form an angle with the ridges 5, which also extend parallel to each other.
  • the two sets of ridges 4 and 5 are located, respectively, at opposite sides of a vertical line 6 extending through the center of the plate lengthwise thereof.
  • each ridge 4 is situated half-way between two ridges 5, and each ridge 5 is situated halfway between two ridges 4.
  • bridges 7 located at intervals along the ridges.
  • the corrugations also form a valley between each pair of adjacent parallel ridges 4 and 5.
  • the bottoms of these valleys are shown by the lines 4a and 5a, respectively, in FIG. 1; but only a few of the valleys are thus shown in order to avoid undue complication of the drawing. It will be apparent that the bottom 4a of each valley forms a ridge on the opposite face of the plate and that each ridge 4 forms the bottom of a valley in said opposite face of the plate, as shown in FIG. 5; and the same is true with respect to the ridges 5 and the valley bottoms 5a.
  • Plates formed according to FIG. 1 may be used in different ways. If a plate interspace is to be provided which offers a relatively small resistance to throughflow of a heat exchanging medium, two plates maybe put together so that one of them is kept in the position shown in FIG. 1, while the other is placed upon the first but turned l around the center line 6. The ridges 4 of the turned plate will thus abut the bridges 7 between the ridges 5 of the underlying plate, and the ridges 5 of the turned plate will abut the bridges 7 between the ridges 4 of the underlying plate. Similarly, the ridges 4 and 5 of the underlying plate will abut the bridges 7 of the turned plate. A plate interspace is thus formed wherein the parallel ridges 4 of each plate extend parallel to the ridges 5 of the other plate.
  • the ridges 5 and their corresponding bridges 7 in FIG. 1 are replaced by turbulence-effecting ridges arranged somewhat differently.
  • the latter ridges haye portions 8 extending in the same direction as the ridges 5 in FIG. 1 and also have other ridge portions 9 extending in other directions, the ridge portions 9 having the same purpose as the bridges 7 between the ridges 5 in FIG. 1.
  • the other ridges 4 and their bridges 7 in FIG. 1 are replaced by ridges (not shown) similar to those shown in FIG. 2 except that the ridge portions 8 extend in the same direction as the ridges 4 in FIG. I.
  • the full lines 8 and 9 may be considered as the modified ridges in the dotted area 11 in FIG. 1, and the dotted lines 8a and 9a may be considered as the modified ridges in the opposing area of the second plate after it has been turned as described above, the latter area corresponding to the dotted area in FIG. 1 before the second plate is thus turned.
  • the valleys between the ridges in FIG. 2 are not shown.
  • the plate shown in FIG. 3 has a number of parallel ridges 12 which extend differently compared to the ridges of the plates in FIGS. 1 and 2.
  • the ridges I2 between which a number of bridges 7 extend as in the plate according to FIG. I, are so located that when two plates are put together, one of them being turned relative to the other 180 around an axis extending perpendicular to the plane of the plate and through the center of the plate, a plate interspace is formed wherein the ridges of one plate extend parallel to the ridges of the opposing areas of the other plate but abut the bridges 7 therebetween. However, if the said one plate is turned relative to the other 180 around the center line 6, a
  • plate interspace is formed wherein the ridges of the one plate cross and abut the ridges of the other plate.
  • the flow will be influenced differently and the different plate interspaces will consequently have different thermal characteristics.
  • the plate shown in FIG. 4 has turbulence-effecting ridges 13 on one side, which are shaped differently compared to turbulence-effecting ridges 14 on the other side of the plate.
  • the central plane of the plate is illustrated by a dotted line 15. All the tops of the ridges on both sides of the plate are situated at the same distance from this central plane.
  • the ridges of a plate having a cross-section according to FIG. 4 may extend across the heat exchanging surfaces as illustrated in FIG. 2, the portions corresponding to the ridge portions 8 preferably having a direction parallel to the short sides (ends) of the plate.
  • a plurality of identical heat exchange plates having respective heat exchange surfaces provided with protuberances acting as turbulence-effecting and spacing means between adjacent plates, said plates being adapted for assembly with marginal gaskets to form plate interspaces for throughflow of two heat exchange media along said surfaces at opposite sides, respectively, of each plate, said plates being characterized in that said interspaces are of equal depth and at least one plate is turned l,80 relative to the other plates around an axis extendingin the plane of the turned plate, said protuberances of each plate being arranged unsymmetrically and so disposed that two different kinds of plate interspaces are formed by said turning of said one plate, thereby creating different flow conditions for the heat exchange media.
  • each plate wherein said protuberances on each side of each plate are formed by ridges extending in parallel spaced relation, some of the interspaces containing ridges of one plate extending parallel to ridges of the adjacent plate, at least one other interspace containing ridges of one plate forming an angle with ridges of the adjacent plate.
  • Heat exchange plates according to claim 2 comprising also bridges extending between the ridges of each plate and acting therewith as spacing protuberances.
