Definitions

  • the present invention relates to improvements made to shell-and-tube heat exchangers and methods of manufacturing such exchangers.
  • the invention is particularly applicable to heat exchangers between a first fluid circulating in a plurality of tubes forming a multitubular bundle, and a second fluid circulating around the tubes, in a cylindrical cavity delimited by a hollow body (or calender) in which extends the bundle of tubes;
  • the invention applies in particular to heat exchangers for heat engines, reducers, inverters, compressors, hydraulic units, etc .; in this type of exchanger, the transfer of heat energy between the hot source and the cold source is effected in particular by conduction through the wall of the tubes; in order to obtain a sufficient energy transfer flux (and / or a heat exchange coefficient), the tubes are made of a material having a high thermal conductivity, such as a copper-based metal alloy, aluminum, nickel, titanium or stainless steels.
  • the invention applies in particular to such exchangers comprising two tubular plates pierced with a plurality of orifices; each of the two ends of each of the tubes is engaged in one of the orifices of a tubular plate and is sealed to this plate in particular by brazing, welding or swaging.
  • the tubular bundle may comprise, in addition to the tubes and the end tube plates, baffles for guiding the flow of the second fluid inside the hollow body; these baffles generally consist essentially of thin plates extending transversely to the tubes and parallel to the end tube plates, are regularly spaced along the tubes and close part of the cross section - generally circular - of the hollow body, to guide the second fluid; the beam may also comprise fins crimped or otherwise related to the outer surface of the tubes of the beam; it may include other secondary surfaces.
  • Such exchangers generally further comprise, at each of its two longitudinal ends, a cap (water box) respectively covering one of said tubular plates, and allowing either the connection of the exchanger to two ducts (external to the exchanger) of transport of the first fluid, ie the guidance of this fluid in the case of a cap "blind", that is to say devoid of connection to an external conduit.
  • the hollow body is provided with an inlet orifice of the second fluid in said cavity as well as an outlet orifice of this fluid;
  • the hollow body is generally constituted by a generally tubular piece provided at each of its two longitudinal ends with an annular flange; each flange is pierced with a plurality of orifices extending along the longitudinal axis of the exchanger and receiving screws - or similar fastening members - for fastening to the body, in a sealed manner, at least one of the tubular plates, as well as the two caps.
  • the body of small exchangers (particularly larger diameter less than 0.25 meters) is generally manufactured by molding (without pressure) a metal alloy, the body and the flanges being molded in one piece; this technique has drawbacks: the inner face of the body must be machined over its entire length to have a roughness and geometric quality compatible with the use that is made of it; the outer faces of the flanges must also be erected; these moldings often have defects in their mass resulting in a porosity incompatible with the function of sealed wall they must fill; moreover, these defects can only be validly checked after mechanical machining (boring, turning, etc.); it is thus necessary to discard expensive parts; the pressure-free molding technique (in sand molds) also prevents the production of thin walls.
  • An object of the invention is to provide such exchangers that are improved, and a method of manufacturing these exchangers that reduces the cost.
  • the invention consists in proposing such exchangers in which a mutual engagement of the shell and the beam forms an abutment inside the cavity delimited by the shell, which prevents or limits a displacement of the beam relative to at the front grille; said exchangers being in accordance with claim 1.
  • This mutual engagement can result from a deformation of a part of the beam and / or part of the shell, or the insertion of a member forming a stop (or shoulder) inside the cylindrical cavity bounded by the grille; in all cases, these deformations and / or insertions are made after the beam has been introduced and correctly positioned inside the shell.
  • this stop is partly at least provided by a projection provided on the inner face of the calender wall, so that it is not necessary to manufacture for this purpose a separate part of the calender.
  • this projection or narrowing forming a stop extends over only a portion of the inner transverse circular contour of the shell.
  • the realization of this abutment is further simplified by making it around one of the fluid inlet and outlet ports in the cavity defined in the shell, in particular by pushing at least a portion of a flange, towards the inside.
  • the projection may be made at the periphery of a thin wall of the bundle, in particular of a tab integral with a tubular plate of the bundle, by pushing this thin wall or tongue towards the outside of the cavity , so as to obtain either a rigid frictional connection between the beam and the shell, or a blockage by penetration of the wall or tongue into an orifice formed in the wall of the shell, in particular in one of said inlet or outlet orifices. fluid outlet.
  • this projection may be incorporated at the end of a connecting part of the shell to a conduit for transporting this fluid - hereinafter referred to as second fluid -; for example, this projection may consist of a tubular portion extending a connection screwed into a threaded hole provided in the wall of the calender; this may allow to obtain a rigid connection between the beam and the shell, which is reversible (removable).
  • this projection consists essentially of a portion of the wall of the shell, and is provided (and / or extends) around one of said orifices (inlet and outlet fluid) to less; preferably, the abutment or projection is adapted to engage in a depression or indentation provided at the periphery of a part of the tubular bundle - preferably at the periphery of a portion of a tubular plate.
  • this part which comprises a first disk-shaped portion pierced with holes for passing and fixing the tubes of the bundle, and a second portion in the form of a tube or circular flange extending longitudinally to from the inner face of the first disk-shaped portion, preferably comprises a notch or depression of substantially circular profile and a diameter adapted to the dimensions of the abutment protruding on the inner face of the calender, this notch or depression being integrated in the second part of the tube plate.
  • such integrated protruding abutments are formed by deformation of a flange provided in the wall of the calender, at the inner end of a passage duct of the second fluid provided in this wall; this production method is particularly simple and inexpensive; this deformation must generally be performed after putting the tube bundle at its final location in the cavity defined by the shell.
  • this method may further include the features of claim 19.
  • a tubular shell-and-tube heat exchanger is described hereinafter, the bundle having two tubular plates, at least one plate - and preferably each - plate comprising: i) a first disk-shaped portion pierced with orifices receiving the tubes of the beam; if necessary ii) a second part extending from the internal face of the first part and incorporating either a housing provided to receive a stop protruding from the inner face of the shell, or an expandable wall or tongue provided for s engage - after deformation - in an orifice formed in the wall of the calender; iii) a third portion of tubular form extending from the outer face of the first portion, and adapted to be engaged in an end of a transport duct of the first fluid fixed to the third part of the plate by forced fitting and / or by strapping; preferably, the third tubular portion comprises for this purpose an outer annular rib.
  • the exchanger 1 comprises a shell 2 of longitudinal axis 3, and a tubular bundle housed in the cavity defined in the shell; the shell has a plurality of flat outer faces 4 to 13 (see figure 3 ) elongate and parallel to the axis 3; on the face 10 open two channels 14 and 15 connecting the cavity defined by the shell to a fluid such as oil to be cooled.
  • the calender is obtained by extrusion of aluminum; the resulting profile is soaked and cut into sections such as that illustrated Figures 2 and 3 ; each longitudinal end is machined to obtain a chamfer 16, 17 facilitating the introduction of the tubular bundle equipped with two annular sealing seals (pins 19, 20 figure 8 ) in the cavity 18 defined by the calender, without damaging the seals.
  • the walls 10 to 12 delimit a longitudinal rib 23 parallel to the axis 3, in which are drilled the channels 14, 15 of axes 21 and 22 radial.
  • each conduit 14, 15 has a threaded outer portion 24 extending from the face 10 to allow the screwing of a not shown fitting; the inner portion of the conduit through which the latter opens on the cylindrical inner face 25 of the cavity 18, has a diameter 26 smaller than the diameter 27 of the orifice through which the conduit opens on the face 10; this results from the presence of an annular flange 28 formed in the wall 23 during the drilling of the ducts 14, 15 by a profiled drill for this purpose; the flange 28 has a thickness 29 sufficiently low (for example of the order of 1 to 2 millimeters) to be deformed by the action of a tool supported on the inner face 30 inclined, according to the arrow 31 figure 4 ; this makes it possible to pass at least part of this flange of the initial configuration - reference 28 figure 4 - where the flange is flush with the face 25, the final configuration - marked 28a figure 4 - Where the deformed flange protrudes from the face 25, a value 32, for example close to one or two mill
  • This mode of deformation of the collar requires the use of a material having sufficient elongation at break, for producing the calender; for this purpose, the use of extruded and tempered aluminum is more favorable than that of cast aluminum and / or injected.
  • the hollow section (or tubular bar) used to form the shell may be obtained by extrusion of plastic material, or by hot spinning or cold drawing of a metal, in particular an aluminum alloy, of copper or steel.
  • the beam 34 comprises a plurality of tubes 35 parallel to its longitudinal axis 33, a plurality of flat baffles 36, 37 perpendicular to the axis 33, and two end pieces 38.
  • the contour of the baffles 36, 37 is largely circular (of diameter adapted to that of the cavity 18) and partly rectilinear 36a, 37a, so that the baffles have a truncated disk shape; the baffles 36 having their rectilinear edge 36a in the lower part are arranged, along the axis 33, alternately with the baffles 37 having their rectilinear edge 37a in the upper part, so that these baffles delimit with the calender a labyrinth forcing the second fluid to follow a sinuous path 39 figure 5 .
  • Each piece 38 has a first portion 380 in the form of a thick disc in which holes are drilled receiving the ends 350 of the tubes 35; this part, which extends transversely to the axis 33, forms the tubular plate itself.
  • the first portion 380 is extended at the periphery of its inner face 3800 by a second portion 381 of the workpiece 38, which is in the form of a short section of thin tube with an axis 33; at one end of this section, a notch 3810 is formed in the tubular wall of the section, which extends in a circular pattern whose diameter 40 is adapted to the dimensions (in particular to the diameter) of the projection 28a ( figure 4 ) formed on the inner face of the shell.
  • the first part 380 of the part 38 is further extended at the periphery of its external face 3801 by a third part 382 of the part 38 which is roughly in the shape of a tube section with an axis 33 and whose external face comprises an annular groove 41 provided for receiving one of the seals (19, 20 figure 8 ) sealing with the calender, and an annular rib 42 which protrudes from the central portion 3820 of this portion 382; the latter can thus, as illustrated figure 7 , receiving one end of a connection tube 43 force-fitted around the rib 42 and the cylindrical portion 3820 against which the tube 43 can be held tight by a strapping collar not shown.
  • each of the notches provided in the end pieces is respectively disposed opposite the inlet and outlet ports 14, 15 and receives a portion of the annular protrusions extending-these orifices, so that the beam is immobilized in the calender.
  • the tubular portion 381 of axis 33 extending tubular plate 380 of the bundle comprises a tongue-shaped portion 3811 which has been deformed after positioning the bundle in the shell, so that it extends inside the the orifice 14 for fluid passage, bearing against the wall delimiting this orifice; the tongue 3811 prevents the beam from sliding in the shell, along their common axis 3, 33 in the direction indicated by the arrow 100; by also equipping the second tube plate (not shown) of the same heat exchanger of such a tongue, it is also prohibited such sliding in the opposite direction, and a rotation of the beam.
  • a tubular sleeve 99 extends inside the conduit 14 for fluid passage drilled in the rib 23 of the shell, along the axis 21 of the conduit 14, on the walls of which leads this sleeve is supported.
  • the sleeve 99 protrudes from the inner face of the calender; therefore, it is engaged in a notch 3810 identical or similar to that described above, so that it limits the sliding of the beam in the calender; by further equipping a second conduit (as marked 15) by a second sleeve projecting inside the calender, the sliding and rotation of the beam in the calender is prevented.
