Definitions

  • the invention relates to a multiple tube bundle heat exchanger.
  • a heat exchanger configuration that includes a plurality of flow-interconnected heat exchange tube bundles.
  • the flow interconnection may relate either to the medium flowing through the tube bundles or to the medium flowing around the tube bundles, or to both.
  • All the tube bundles run between two tube plates common to all the tube bundles, and the head chambers above each of the tube plates are subdivided into partial chambers to form an inflow distributor chamber for the primary medium for distribution to the tubes of the first tube bundle, then a series of connecting chambers, disposed above the one tube plate or the other, for connecting respectively the outlet ends of the tube bundle to the inlet ends of an adjacent tube bundle, and, finally, an outlet collecting chamber above the outlet ends of the last tube bundle in the flow series connection.
  • Between the individual tube bundles are disposed, in the housing, partitions that respectively have overflow orifices near one tube plate or the other so that the secondary medium flows into a tube bundle chamber. The medium then passes through the overflow orifices from tube bundle chamber to tube bundle chamber and finally out of the last tube bundle chamber into an outlet.
  • a multiple tube bundle heat exchanger including axially opposite tube plates, a plurality of tube bundles disposed between the tube plates, each of the tube bundles including an independent tube bundle subassembly forming an integral unit having at least one heat exchanger tube with two axial tube ends, the subassembly made from the at least one heat exchanger tube and respective tube plates fastened to the two axial tube ends, a housing having a casing part defining a interior and having two axial housing ends with flanges, removable head pieces to be fastened to the flanges, the head pieces respectively disposed at the two axial housing ends, and partitions subdividing the interior into a number of chambers, the number of the chambers corresponding to a number of the plurality of tube bundles, each of the chambers receiving one of the tube bundles, the tube plates and the head pieces respectively forming seals, and the tube plates delimiting at least one of distributor chamber
  • the chambers are casing spaces.
  • the partitions have, at both of the axial housing ends, selectively closeable overflow orifices for overflow of medium flowing through the chambers between adjacent ones of the chambers.
  • the intermediate pieces form an axial prolongation of the partitions.
  • the intermediate pieces have selective overflow orifices between adjacent ones of the chambers.
  • each of the chambers has an inlet and an outlet, the inlet and/or the outlet is disposed at a respective one of the intermediate pieces, and the inlet and/or the outlet is disposed laterally on the respective one of the intermediate pieces, or disposed axially on a respective one of the intermediate pieces and led through a respective one of the head pieces.
  • the concept according to the invention provides for using standard heat exchanger tube bundles together with standard housing sub-assemblies that allow a multiplicity of combination possibilities and, of course, also heat exchanger configurations of different size.
  • FIG. 1 is a cross-sectional view of a counter-current heat exchanger according to the invention constructed from a multiple configuration of tube bundles and having a parallel flow connection of the tube bundles;
  • FIG. 2 is a cross-sectional view of an alternative embodiment of the counter-current heat exchanger of FIG. 1 with a plurality of tube bundles, flow-connected in series;
  • FIG. 3 is a cross-sectional view of an alternative embodiment of the counter-current heat exchanger of FIG. 1 with a plurality of tube bundles, flow-connected in parallel, and with an alternative housing configuration;
  • FIG. 4 is a cross-sectional view of an alternative embodiment of the counter-current heat exchanger of FIG. 3 with a plurality of tube bundles, flow-connected in series, and with a housing configuration developed in relation to the configuration according to FIG. 2.
  • FIG. 1 there is shown a heat exchanger having a housing and a plurality of tube bundles disposed therein.
  • the housing is made of a casing 1 , on which are disposed an inlet connection piece 11 and an outlet connection piece 12 respectively introducing and discharging a secondary medium into and out of the casing spaces.
  • On both axial ends of the casing 1 are flanges 13 and two head pieces 2 , 3 , which are disposed adjacent to the ends of the casing 1 on both sides.
  • the head pieces 2 , 3 respectively have an inlet and an outlet connection piece 21 , 31 for a primary medium to be conducted through the tube bundles.
  • the head pieces 2 , 3 are each assigned a cover plate 22 , 32 that can be clamped together with the flanges 13 of the casing 1 by screws or threaded rods 23 , 33 .
  • a plurality of tube bundles 5 are installed in the housing.
  • Each tube bundle includes a number of parallel heat exchanger tubes 51 disposed at distances from one another and a tube plate 52 is respectively connected to these and located at the two axial ends of the tube bundle.
  • Each tube bundle including the heat exchanger tube 51 and the associated tube plates 52 forms a subassembly in the form of an integral unit and is installed as such in the housing.
  • the seals 53 used for sealing off between the casing 1 , head pieces 2 , 3 , and the tube plates 52 are illustrated diagrammatically in the drawing and can easily be recognized as stylized O-ring seals, while, of course, the actual nature of the seals 53 used may be selected in any desired way, as required.
  • the housing space within the casing 1 is subdivided by installed partitions 14 into a number of casing spaces 10 A, 10 B, 10 C corresponding to the number of tube bundles 5 .
  • the partitions 14 are provided at the top and bottom with passage orifices 15 through which the individual casing spaces 10 A, 10 B, 10 C are connected to one another.
  • the passage orifices can be selectively closed.
  • the head chambers which are formed in the head pieces 2 , 3 , are not subdivided, but extend over all three tube bundles, so that a parallel flow through the three tube bundles 5 A, 5 B, 5 C takes place.
  • the three tube bundles 5 A, 5 B, 5 C are, therefore, flow-connected in parallel.
  • FIG. 2 shows a configuration that, again, includes a housing 1 with three tube bundles 5 A, 5 B, 5 C installed therein.
  • the construction of the housing with a casing 1 , head pieces 2 , 3 , and connection pieces 11 , 12 , 21 , 31 for the media involved in the heat exchange and the subdivision of the casing interior by partitions 14 into three casing spaces 10 A, 10 B, 10 C correspond to the configuration according to FIG. 1.
  • the three tube bundles 5 A, 5 B, 5 C in FIG. 2 are constructed in the same way as those in FIG. 1 and, again, respectively include heat exchanger tubes 51 and a tube plate 52 at the two opposite axial ends, each tube bundle 5 A, 5 B, 5 C, again, constituting an integral unit or subassembly made of these parts.
  • the head pieces 2 , 3 and the partitions 14 in the casing 1 are modified such that, in the configuration in FIG. 2, the three tube bundles are flow-connected in series.
  • the secondary medium flowing in through the connection piece 11 and flowing out through the connection piece 12 is routed, in all three tube bundles, in counter-current to the primary medium that flows in through the connection piece 21 and flows out through the connection piece 31 and that flows in succession through the heat exchanger tubes 51 of the three tube bundles.
  • the head pieces 2 and 3 are modified such that an inlet chamber 24 is formed above the inlet end of the first tube bundle 5 C, as seen in the direction of flow of the primary medium.
  • an overflow chamber 35 , 25 is formed respectively in the head pieces 3 , 2 for transferring the primary medium between the adjacent ends of two fluidically successive tube bundles (from 5 C to 5 B through the overflow chamber 35 or from 5 B to 5 A through the overflow chamber 25 ), and an outflow chamber 36 is formed above the outflow end of the last tube bundle, as seen in the direction of flow of the primary medium, that is to say 5 A.
  • Partitions 27 , 37 for appropriately subdividing the head piece space into the corresponding chambers are, therefore, formed in the head pieces 2 , 3 .
  • each overflow orifice 15 is provided in each of the partitions 14 and is located near the respective tube plates so that a secondary medium must in each case flow, in countercurrent to the medium flowing through the tube bundle, through essentially the entire axial length of the respective casing chamber until it can flow over through the respective overflow orifice 15 into the adjacent casing chamber.
  • standard partitions 14 may be used, which, as illustrated in FIG. 1, may have, at both axial ends, overflow orifices, one of which is closed in each case to produce a configuration according to FIG. 2.
  • FIGS. 3 and 4 show configurations similar to those according to FIGS. 1 and 2, to be precise, a multiple tube bundle heat exchanger with tube bundles flow-connected in parallel (FIG. 3) or with tube bundles flow-connected in series (FIG. 4). Identical or corresponding parts are, again, given the same reference symbols as in FIGS. 1 and 2.
  • the tube bundles 5 A, 5 B, 5 C (of which there are, again, for example, three in each case) correspond to those according to FIGS. 1 and 2.
  • the head pieces 2 , 3 also correspond to those according to FIGS. 1 and 2. The same applies to the casing 1 with the connection pieces 11 , 12 .
  • FIGS. 3 and 4 differ from the configurations according to FIGS. 1 and 2 in a modification or development of the housing structure.
  • the partitions 14 are configured without overflow orifices, that is to say, are completely closed.
  • the head pieces 2 , 3 are each supplemented by an intermediate piece 4 that is disposed between the respective head piece and the flange 13 of the casing 1 and that forms prolongations of the partitions 14 , or, where overflows are provided between adjacent casing spaces, have an overflow orifice 41 .
  • the casing part 1 of the housing, together with the partitions 14 can be configured as a standard part, while different intermediate pieces 4 can be kept ready, as required, as parts to be used in a modular manner to produce overflow orifices between the casing spaces.
  • connection pieces for the casing space may also be disposed on the intermediate pieces 4 .
  • connection pieces for the casing space may also be disposed on the intermediate pieces 4 .
  • the concept according to the invention makes it possible to construct any desired heat exchangers using standard components.
  • the tube bundles may be configured as standard components, from which any desired multiple tube bundle heat exchanger configurations of different size can be constructed, regardless of the intended operation as co-current or counter-current heat exchangers.
  • different housing structural parts to be precise casings and head pieces, may be kept ready, these respectively being configured to receive a specific number of tube bundles, or variable block configurations of such housing structural parts may be provided.
  • head pieces to be precise, one for the tube bundles operating in parallel and one for the tube bundles connected in series, heat exchanger configurations can be constructed as required from relatively few basic components in a modular manner and, therefore, highly economically.
