Definitions

  • ABSTRACT A plate-type heat exchanger having a stack of mutually spaced parallel plates defining at least two sets of passages in heat-transferring relationship and spacers between PLAID; HEAT the plates for maintaining same in spaced relationship. At least 6 Clams 8 Drawmg one wall in said housing laterally flanks the stack and is in con- U.S. Cl 165/166 tact therewith along an inner surface of the wall while the wall Int. Cl F28f 3/00 defines a pressurized chamber along its outer surface.
  • the Field ofSearch 165/157, spacers are corrugated members between each pair of said 166.167.168.164-166 plates.
  • the present invention relates to a plate heat exchanger and, more particularly, to a lightweight, simply constructed heat exchanger, especially for cryogenic processes such as Linde- Frankl air rectification.
  • plate heat exchangers of this type are fortned internally with numerous plates and are sealed along the sides of the plate assembly by lateral housing plates which are soldered or welded to the heat-exchange plates.
  • the soldering step involves considerable complication since efficient heat exchangers are characterized by numerous plates in the stack and relatively small intcrplatc spacing, thereby making it necessary to solder or weld a large number ofjoint end seams.
  • the principal object of the present invention to provide a plate heat exchanger which avoids the aforementioned disadvantages and can be produced in a simple, convcnient and inexpensive manner.
  • Still another object of this invention is to provide a plate heat exchanger, especially designed for use in cryogenic systems and particularly those for the rectification of air, which has a high efficiency and fluid throughput.
  • a heat exchanger having a stack of plates with intervening supporting elements, the stack being bounded laterally with at least one pressure wall which clamps the stack against an opposing wall, the latter preferably being under pressure as well.
  • These walls preferably lying parallel to the plates of the stack. are formed along their sides turned away from the stack (Le. verso) as one wall of a pressure chamber to which the fluid is supplied at elevated pressure.
  • the ex ternally applied pressure moreover, acts to counter the pres sure within the heat exchanger and thereby prevents forces from developing which may damage the unit.
  • the externally applied pressure also serves to stiffen the lateral wall or walls of the heatcxchanger chamber and stack against outward forces applied to this wall when the heat exchanger is in use and thus further serves to limit deformation of the heat exchanger or the plates of the stack.
  • the heat exchanger which may also be of any type other than the air rectification heat exchanger mentioned earlier, com prises a stack of mutually spaced parallel plates defining at least two sets of passages in heat-transferring relationship via these places.
  • a spacer means is interposed between the plates for maintaining them in spaced relationship under pressure from without, thereby ensuring constant flow cross section and stability in spite of the externally applied pressure.
  • the heat exchanger has a housing at least one wall of which flanks the stack and contacts the latter (tug. at one of the plates or spacers) along an inner surface of the wall; the outer surface of the latter is subjected to fluid pressure from at least one chamber defined between the wall and a housing.
  • the pressurizable wall may thus comprise a so-called pressure bottom.
  • the stack of heat-exchanger plates is received between or flanked by a pair of such pressurizable walls which extend parallel to one another at opposite sides of the stack.
  • the walls also may run parallel to the plates which, within the heat-exchange zone, are substantially coextensivev with the pressurizable walls; the latter may, however, extend out of the heatexchange compartment beyond the stack.
  • the housing defines with each of the pres surizable walls, along the outer surface thereof, a respective chamber individual to that wall.
  • a common chamber can surround the heat-exchanger compartment and encompass both pressurizable walls or more such walls if provided.
  • a relatively massive, i.e.pressure-re' sistant, wall is rigid with the housing and bears upon one side of the stack in a manner analogous to the arrangement of one ofthe pressurizable walls mentioned earlier.
  • a somewhat thinner, pressure-yielding wall bears upon the stack at a pressure applied front without front a chamber within the housing at this opposite side of the stack.
  • the relatively massive wall is drawn against the stack by the reaction force generated in the chamber.
  • Each of these means may include an inlet manifold or distributing chamber for feeding the fluid to the mutually parallel passages and also includes a collecting means for gathering the fluid passed through the corresponding passages,
  • This system has proved to be satisfactory in cases in which pressures are different in the different sets of fluid passages.
  • condenser-evaporators for air-rectification installations e.g. columns of the Linde-Frankl type
  • manifold feed chambers and manifold collecting chambers are provided with manifold feed chambers and manifold collecting chambers on opposite sides of the housing in comntunication with the respective sets of passages, the high-pressure system ofwhich is connected to the pressurizable chamber.
  • the stack of heat-exchanger plates comprises a plurality of generally flat. mutually spaced parallel plates of identical configuration separated by a spacer means in the form of one or more generally corrugated members.
  • the expression generally corrugated is used herein to describe zigzag, folded, undulat ing or wavy members having alternating crests and hollows, the crests and hollows being of angular or arcuate configuration.
  • the generally flat plates are separated by shectlikc corrugated spacers which have alternating crests resting against the opposite plates of a respective pairso that each plate defines with the spacer sheet a channel through which the heat-exchange fluid can be passed.
  • the channels of all of the plates may be parallel to one another and codirectional or, in accordance with another feature of this invention, oriented in different directions so that, for example, alternate sheets are turned orthogonally with respect to one another.
  • Still another modification provides that the spacer elements, which lend rigidity to the stack, are constituted by strips spaced apart between the respective pairs ofplates but generally extending parallel to one another. It has been found to sufficewhen the high-pressure fluid acts upon the spacer sheets or members at spaced-apart locations so as to define, in effect, high-pressure ribs which increase the rigidity of the stack.
  • the support members can be relatively thinwalled elements which have their spacer effect reinforced by the presence of high-pressure (or low-pressure) fluid in the passages which they define with the plates.
  • high-pressure or low-pressure
  • alternating passages for the highand low-pressure fluid are provided along the stack so that the low-pressure passages or compartments are supported by the respective spacers and together therewith withstand the higher pressure.
  • the corrugated sheets are used. however. it is desirable to alternate between highand low-pressure channels between each set of plates and along the hollows and troughs thereof.
  • FIG. I is a vertical cross section through a plate-type heat exchanger serving as a condenserevaporator for a cryogenic installation;
  • FIG. 2 is across section taken along the lines II-Il of FIG. 1'.
  • FIG. 3 is a cross section along the lines Ill-lll of FIG. I;
  • FIG. 4 is a cross section generally along the lines IV-IV of FIG. 1 but directed to another embodiment
  • FIG. 5 is a cross-sectional view of still another plate-heat exchanger
  • FIG. 6 is a cross scctional view of a single-chamber heat exchanger
  • FIG. 7 is a detail view ofthe system of FIG. 6.
  • FIG. 8 is a cross-sectional detail view corresponding to a modification ofthe system of FIG. 7.
  • FIGS. 1 and 2 show a heat exchanger adapted to the use as a condcnser-cvaporator fora Lindc-Frankl air rectification installation in which the heat exchanger step is formed with a first set of passages l and a second set of passages 2 defined between mutually parallel spaced-apart plates 3 which have not been shown with wall thickness in FIGS. I and 2 so as to maintain the proportion of the drawing. Between the plates 3 which define the passages I and 2 in pairs. I provide undulating sheets for a corrugated sheet metal (seen in cross section in FIG. 2) in the space forming the passages I. In the alternate spaces. defining the passages 2. I have provided a plurality of spaced-apart strips 5 which are also of corrugated or zigzag configuration but are welded on a bias (see FIG. 3) to hold the plates 3 apart.
  • the resulting stack of heat exchangers is flanked by a pair of pressuredeformable walls 6 and 7 which lie parallel to the plate 3 and are generally coextensive therewith within the heat-exchange compartment H.
  • these walls rest against the stacks but have an overall height 8 (FIG. I) such that they extend somewhat beyond the plates and the chamber H to form part of the housing.
  • the walls 6 and 7 are welded at seams 6a. 7a to the lower and upper plates 9 and 10 which. together with walls 6 and 7. enclose the hcatexchange compartment H.
  • a pair of domes 20a and 2Iu are also welded at 60. 7a to the walls 6 and 7 so as to define pressurizable chambers 20. 2] with the outer surfaces I8 and [9 of these walls.
  • the bottom plate 9 is perforated at 14 to allow liquid oxygen to pass through into a distributing compartment I2 and then through the latter into the passages 1. Communication between the passages I and the distributing chamber I2 is established between the plates of alternate pairs, the other pairs being provided with filling strips 16 and 17 so as to seal their interior. Above the plate 3 and below the upper plate 10. there is defined a collecting compartment I3 into which the vaporizable or vaporizing medium passes for further movement into the column via the perforation in plate 10. As oxygen passes upwardly through the channels I. it is vaporized in heat exchange with nitrogen in passages 2. the nitrogen being liquefied in the process. The vaporized oxygen passes out through the collecting compartment 13 and the perforations 15 previously mentioned.
  • the filler strips 16 and I7 enclose the spaces between plates 3 which define the passages 2 and also prevent the nitrogen from entering the distribution compartment 12. the passages I and the collecting compartment l3.
  • the gaseous condensable medium. in this case nitrogen. is introduced at a distribution compartment 22 which communicates with the passages 2 while. in the rcgion of this compartment, the passages l are scaled from the compartment by filler strips 25.
  • a similar chamber on the opposite end ol'the stacks is provided to collect the uncondcnsed nitrogen if desired. Since the gaseous medium is at elevated pressure with respect to the oxygen, I have found it to be advantageous to connect the pressure chambers 20 and 21 with the inlet compartment 22. To this end, I provide passages 23 and 24. the former being bored through extensions ofthe pressurized walls 6 and 7.
  • the filler strip 25 prevents leakage of oxygen into the nitrogen space as well as leakage of the nitrogen into the oxygen passages.
  • FIG. 3 shows a section through one of the nitrogen passages terminating in the distribution compartment 22. Partitions 29 and 30 close off the compartment 22 from the inlet and outlet manifold chambers I2 and 13.
  • the bias-folded spacer strips 5. which are of corrugated sheet metal (FIG. I) extend downwardly from the plate I7 but terminate short ofthe lower plate 15 to enable the liquid nitrogen to pass along the latter for collection in any desired manner.
  • the strips 5 need be dimensioned only to withstand the relatively low pressure in the oxygen passages I in the event of failure of the nitrogen pressure in passages 2. Approximately halfway along the upper strip I7 of each of the passages 2.
  • I provide a bore 26 and a leadout tube 28 whose hood 27 overlies the bore 26 to collect the helium gases of the hood 27 where the system is used for the rectification of air. In this manner. the helium is prevented from mixing with the oxygen in the space I3.
  • FIG. 4 there is shown a modification of the system of FIGS. I through 3 corresponding to a section along the line lV-lV of FIG. I. and in which the corrugated sheets in the passages l are subdivided vertically into three sealed sections collectively represented at 104 but individually shown at 1040, l04b and 1040.
  • FIG. 5 shows an embodiment of this invention wherein the housing consists of a cylindrical shell 232 which encloses a pressure chamber 232a common to both of the lateral walls 206. 207 flanking the stack which is made of plates 203 defined in passages 201 and 202 and separating sheets 204 or corrugated strips 205. all as previously described with respect to passages I. 2, plates 3, spacers 4. Sand walls 6. 7. The exterior surfaces 218 and 219 of the walls 206. 207 are exposed to the pressure in the chamber 232a. A pair of coaxial cylindrical segments 209 and 210 are welded to the pressureyieldable walls 206. 207 and define with the stack the feed and collecting compartments 212 and 217 or one of the heatexchange fluids. Filler strips 216 and 217 prevent the other fluid from leaking into the first fluid space and vice versa.
  • the stack comprises mutually spaced parallel plates a. 35b, etc. and rests against the rigid, nonyieldable and relatively massive wall 38 at the right-hand side of that housing.
  • the pressure-yieldable wall 37 at the other side of the housing, bears against the other side of the stack at the pressure within the chamber 44 and acts upon the outwardly turned face 43 of this wall 37.
  • a spacer sheet 36 of corrugated configuration such that the crests 45 of each sheet bear upon one of the plates 35a. 45b alternately while the remaining crests bear upon the opposed plates.
  • Upper and lower walls 41 and 42 secure the massive wall 38 to the chamber 44 and define. with the stack. the collecting compartment and the feed compartment ofone of the stacks of passages.
  • Chamber 47 is connected with the high-pressure fluid passages in the manner described earlier.
  • the corrugated sheets 36 serve to reinforce the plates 35a. 35b, etc. against compressive and expansive forces and also to limit deformation of the individual plates within the heat-exchanger stack.
  • the hollows of these corrugated sheets define passages 39a, 39. a and 40 which alternate with one another and are sealed against leakage therebetween When high-pressure fluid is introduced into the hollows 41, 40 and 40a, for example, low-pressure fluid can be introduced into the alternate channels 39a.
  • FIGS. 7 and 8 there is shown to detail views of a heatexchanger stack according to this invention wherein, as in FIG. 5, filler strips 47, 48 seal the peripheries of the respective passagesln the same system of FIG. 7, planar plates 50 are separated by corrugated sheets 51 to define the alternating channels 54 and 55 which are supplied with the different fluids to be brought into heat-exchanging relationship.
  • Air can, in the system of FIG. 7. pass through both sets of passages 54. 55 in countercurrent to another medium, for example nitrogen. which is passed through the adjoining passages. Alternatively. the nitrogen can he passed through the passages 55, for example. while the nitrogen is delivered to the passages 54.
  • the corrugated plate 351 is shown to he turned at right angles to the plates 5l so that transverse flow rather than countercurrcnt flow can be achieved.
