Definitions

  • the invention relates to a heat exchanger, in particular of the type comprising a large number of first flow paths of a first fluid of a first temperature made of a thermally conductive material and extending axially in a hollow casing traversed by a second fluid a second temperature different from said first temperature in heat exchange contact with said first channels.
  • the object of the present invention is to propose a heat exchanger of the type indicated above, which does not have the disadvantages which have just been stated.
  • the heat exchanger according to the invention is characterized in that it comprises flat, parallel tubes, juxtaposed in the direction of their width inside the casing, at a predetermined distance from each other others, and whose internal space is divided by intermediate means into a thermally conductive material in a plurality of axial channels parallel which constitute said first flow paths.
  • the second fluid flows through the spaces between adjacent flat tubes and each space is divided by intermediate means of thermally conductive material in one plurality of second channels.
  • the second channels extend parallel or perpendicular to the first canals and lead to their two ends respectively in a perpendicular inlet channel and a perpendicular outlet channel in communication with orifices inlet and outlet respectively in the wall of the casing.
  • the heat exchanger shown by way of example not limiting in the figures, essentially comprises a hollow casing 1, advantageously made of cast iron or a composite material which encloses, surrounded an envelope 2, a plurality of flat tubes 3 made of a material thermally conductive, parallel, juxtaposed in the direction perpendicular to the long axis of their cross section, at a distance predetermined from each other.
  • the envelope 2 surrounding the tubes 3 has a cross section substantially rectangular, in the example shown square, in the measurement where the housing has a circular cross section.
  • the tubes 4 are fitted at each end and fixed, for example by brazing, sealingly, in a collecting plate 5 and 6.
  • the plate manifold 5 in the form of a flange is mounted on the right end of the casing 1, which is open and forms part of an inlet and outlet manifold 7 for a fluid F1 as symbolized by arrows.
  • the internal chamber 8 of the collector 7 is separated into two parts communicating respectively with inlet 9 and outlet 10.
  • the manifold plate 6 located on the closed side of the casing 1 is mounted on a fluid transfer or return box 12.
  • the fluid F1 which enters via the inlet fitting 9 in the collecting part of the manifold chamber 8 flows through one half of the tubes 3 in the direction of the collector plate 6 and is returned by the collector of transfer through the other half of the tubes 3 into the outlet fitting 11.
  • the five upper tubes can be considered as being connected to the inlet fitting 9 and the five lower tubes to the outlet fitting 10.
  • each flat tube 3 is divided by an intermediate strip 14 which is serpentine and in a plurality of channels 15 parallel to the axis of the tube (in particular Figures 3 and 4).
  • an intermediate strip 17 of the same type also folded into a serpentine, the space 18 separating two adjacent flat tubes 3 is separated into a plurality of parallel channels 19.
  • the channels 19 are parallel to the channels 15 of the flat tubes 3.
  • FIGS. 1 and 4 it can be seen that the channels 19 delimited between two tubes 3 communicate with one end with transverse channels 21, also formed by a intermediate strip 22 between the same two tubes 3, which open in the internal space portion 23 of the casing 1 through a window 24 in the wall side of the envelope 2.
  • the space part 23 constitutes the entry space a second fluid F2 which can enter this space through a fitting inlet 25.
  • the other end of the axial channels 19 communicates by through transverse channels 27 with the internal space portion 28 of the casing constituting the fluid outlet space F2 which can flow out of the casing through an outlet fitting 29.
  • the transverse channels 27 open of course in space 28 through a window 30 in the side wall of the envelope 2.
  • These channels 27 are also formed by a strip interlayer 22 'serpentine folded between the same two tubes 3. It can be seen still that the inlet 23 and outlet 28 spaces of the casing 1 are separated by a sealing ring 32.
  • the configurations of the intermediate strips constituting these two series of channels are illustrated in FIG. 1 and in particular on the Figure 4.
  • the intermediate strips are made of a material thermally conductive and fixed in any suitable manner, in particular by brazing or gluing on the internal or external faces of the tubes along their crest lines, depending on whether it is an axial or transverse interlayer.
  • the circulation of the fluid F2 is done according to a Z configuration, with inlet at one end of the housing and outlet at the other end of the housing, but on the opposite side, the flow being of the counter-current type with regard to the inlet and parallel flat tubes with regard to relates to the outlet tubes 3.
  • FIG. 5 schematically illustrates, in a view similar to FIG. 1, the arrangement of the interlayer channels 21 and 27 to obtain circulation of the fluid F2 in U.
  • FIG. 6 schematically illustrates the configuration of the spacers between tubes to obtain a hairpin circulation of the fluid F2. In this case, the inlet and outlet of this fluid are on the same side of the casing.
  • FIG. 7 schematically illustrates the construction of an exchanger in which fluid F2 flows against the current as well with respect to the inlet tubes and indicated respectively by numbers 32 and 33.
  • Figure 8 shows that the internal space of the casing 1 is separated into these inlet and outlet parts 35 and 36 corresponding to parts 23 and 28 of Figure 1 by partitions axial sealing 37.
  • These partitions may be provided with valves (not shown) whose opening is controlled according to temperatures fluids.
  • Such temperature sensitive valves could be made advantageously in a shape memory material, known per se.
  • FIG. 9 schematically shows an embodiment of the heat exchanger heat with a cross configuration of the F1 and F2 fluid circulations.
  • the fluid circulation channels F2 extend, in each space between two adjacent flat tubes and between the outer tubes and the envelope surrounding them, perpendicular to these tubes.
  • the axial central part of each space between tubes, indicated at 39 on the Figure 9 is cleared to allow the axial flow of the fluid F2 between the fluid inlet and outlet ports F2 of the casing whose internal space is divided into an entrance space 40 and an exit space 41, separated by a sealing ring 42.
  • collector plates 43 and 44 These plates are mounted so waterproof in the housing.
  • the fluid F1 circulates through the exchanger in one pass.
  • the casing will be closed at the level of the collector plate. 44, and this will be part of a transfer collector of the same type as the manifold 12 of FIG. 1.
  • the fluid F2 its flow could also be carried out in a configuration in several crossed passes.
  • the central axial part of axial flow of fluid F2 it could also be made by providing two rows of juxtaposed flat tubes, indicated at 46 and 47 in Figure 9.
  • FIG. 11 shows several portions of tabs 48 to 52 which are offset and thus constitute a network of communicating channels 53 in broken lines. It should be noted that what matters for the thermal performance of the exchanger is the exchange surface obtained by mounting the dividers.
  • the invention presents considerable advantages compared to the heat exchangers known in since it replaces a large number of individual tubes used in the latter by a relatively small number of flat tubes but of which the internal space is divided, like the space between the adjacent tubes, by interlayers in a large number of channels.
  • the advantages mechanical of the invention thus adds an improvement in performance compared to the state of the art.
  • fluids F1 and F2 can be of any suitable nature, they are formed in particular by liquids.
  • Another major advantage of the invention lies in the fact that the assembly constituent parts of the heat exchanger is easy. Indeed, the relatively thick collector plates in which the tubes ensure, during assembly, the necessary mutual maintenance of parts to assemble. This removes holding devices specific essential when assembling heat exchangers of the plates.
