Definitions

  • the present invention relates to improvements made to the shell-and-tube heat exchangers and methods of manufacturing these exchangers.
  • the invention is particularly applicable to heat exchangers between a first fluid flowing in a plurality of tubes forming a multitubular bundle, and a second fluid circulating around the tubes, in a delimited cylindrical cavity by a hollow body (or calender) in which the bundle of tubes extends;
  • Typical applications heat exchangers, gearboxes, inverters, compressors, hydraulic units ...; in this type of known exchanger, the transfer of thermal energy between the hot source and the cold source is carried out in particular by conduction through the wall of the tubes; to obtain a transfer flow of energy (and / or a heat exchange coefficient) sufficient, the tubes are made in a material having a high thermal conductivity, such as a metal alloy with base of copper, aluminum, nickel, titanium or stainless steels.
  • the invention applies in particular to such exchangers comprising two tubular plates generally disc-shaped, which are pierced with a plurality of holes, and in which each of the two ends of each of the tubes is engaged in one of the orifices of a tubular plate and is secured in a sealed manner this plate in particular by soldering, welding or swaging.
  • the tubular bundle generally comprises, besides the tubes and the plates tubular end, baffles for guiding the flow of the second fluid inside the hollow body; these baffles are usually basically formed by thin plates extending transversely to the tubes and parallel to the end tube plates, are evenly spaced along tubes and close part of the cross section - usually circular - hollow body, to guide the second fluid.
  • Such exchangers generally comprise, in addition, at each of its two longitudinal ends, a cap (water box) covering respectively a said tubular plates, and allowing either the connection of the exchanger to two conduits (external to the exchanger) for transporting the first fluid, ie the guiding of this fluid in the case of a cap "blind", ie devoid of connection to a external conduit.
  • the hollow body is provided with an inlet orifice of the second fluid in the said cavity as well as an outlet of this fluid;
  • the hollow body is usually consisting of a generally tubular piece provided with each of its two longitudinal ends of an annular flange; each flange is pierced with several orifices extending along the longitudinal axis of the exchanger and receiving screws - or similar fastening members - for securing to the body, in a sealed manner, at least one of the tubular plates and the two caps.
  • the body of the small heat exchangers are usually manufactured by molding (without pressure) of a metal alloy, the body and the flanges being molded in one piece;
  • this technique has disadvantages: the face internal body must be machined along its entire length to have a roughness and a geometric quality compatible with the use made of it; the faces outer flanges must also be erected; these molded parts frequently have defects in their mass resulting in porosity incompatible with the waterproof wall function they must perform; in addition, these defects can only be validly checked after mechanical machining (bore, turning ...); it is thus necessary to discard expensive parts; the pressure-free molding technique (in sand molds) also prevents to make thin walls.
  • An object of the invention is to propose such exchangers which are improved, as well as a method of manufacturing these exchangers which make it possible to reduce the cost.
  • the invention consists of a method of manufacturing such exchangers, in which a blank of the hollow body is produced by extrusion of a material for forming a hollow section, and in which a section of said section is cut shaped; this method makes it possible to obtain a blank delimiting a cylindrical cavity of generally circular section whose geometry and surface state are good enough to avoid the need for subsequent machining of the inner face of the wall of the body even when the end of this wall forms a scope for joints; using a homogeneous material and thanks to the pressurization of the material allowing its passage through the die, we obtain a blank free from defects (micro cavities), and therefore non-porous.
  • the invention consists in proposing such exchangers the hollow body consists essentially of one or more sections of profile extrusion molded, and does not have an end flange.
  • the profile (or contour) - in a cross section - external of the external face of the hollow cylindrical body is not entirely circular: this profile external may have at least one rectilinear segment that is tangent to a first circle concentric to a second circle corresponding to the transverse profile of the inner face of the wall and / or the body; to this rectilinear segment of the external profile corresponds to a flat part of the external face of the hollow body; this flat face thus extends preferably tangentially to a cylinder coaxial with the hollow body, in a part of the body wall which has said inlet and outlet ports said second fluid; this facilitates the mechanical connection to the hollow body of two external conduits for transporting this fluid; preferably this part of the wall of the body, which extends under (opposite) this flat face, is provided with a thickness greater than the average thickness of the tubular wall of the body; this results in a wide rib (or longitudinal boss) which facilitates the realization of said orifices under tapped holes adapted to receive
  • the transverse external profile of the body may preferably comprise other rectilinear segments, to which correspond salient ribs (or many recessed grooves) formed on the outer surface of the hollow body and extending longitudinally; in particular these ribs or grooves can marry an I, V or U profile and can be used to fix the body (and the exchanger) on a support, and / or to the connection connection connection of the transport conduits of the second fluid (Figure 9).
  • the exchangers according to the invention do not comprise rigid connection means between the hollow body and the tubular bundle, the mechanical connection between these elements resulting essentially from the contact (support) forces acting between these two parts through two first sealing members such as two seals O-rings, which are flattened (compressed) between two cylindrical bearing faces (or carried) respectively on each of these two pieces; in the absence of these sealing members, the beam can freely slide in the body cavity; in the presence of these sealing members the beam can slide in the cavity under the action of a sufficient effort, especially under the action of the elongation of tubes of the bundle, due to their thermal expansion; each of said bodies Sealing is usually housed in an annular groove; preferably these grooves are provided on the outer face of the tubular plates; this avoids the realization (more expensive) grooves on the inner face of the wall of the hollow body; it then only requires the completion of a chamfer at its end (s) internally (s), which allows to introduce by sliding a beam whose plate tubular is provided with the seal without damaging the seal and facilitating
  • each cap is respectively attached to one or other of the plates of the bundle, by means of a first rigid connection means provided in part center of the outer face of the plate, such as a tapped hole, and through a means guide and support which is provided in the central part of the cap, such as a socket (or insert), which is adapted to receive a second rigid connection means - such as a screw complementary to said first rigid connection means.
  • a second annular sealing member which is preferably in support (radial) on two cylindrical faces respectively provided on the plate on the one hand and on the cap on the other hand, the sealing member being slightly crushed (compressed) between these two faces arranged coaxially and facing one another; in arranging these two faces respectively at each end of the plate tubular on the one hand and the cap on the other hand, we obtain a commitment of these bearing faces (span) of seal with the seal to form a tight assembly, in exerting a relatively small effort that may result from reciprocal engagement said rigid connection means provided in the central part of the cap and the plate, in particular by screwing a single screw; these efforts are far less than those to be exerted to ensure a tight connection by a crushed O-ring between two flat parallel support faces, as is the case in the flange connections.
  • each of said two plates tubular end comprises a groove receiving said first sealing member with the hollow body, and comprises a countersink opening on its outer face and carrying said second sealing member with the associated cap, and the length of the body hollow is greater than the distance separating the two grooves respectively provided on each of the tube plates and is less than the distance separating the two counters; therefore, the first sealing members are (after assembly) arranged recessed from the ends of the body and the second sealing members are disposed beyond the ends of the body, that is to say outside of it; he in the event of a fault in one of these sealing members producing a leak of one or the other of the two fluids, the leakage current flows outside the body and is therefore identifiable; in addition, no mixing of these two fluids can result from such default.
  • the sealing means between the tube plate and the cap allows to use, for the realization of the cap, a resistance material mechanical medium and thin, such as a plastic case optionally reinforced with mineral fibers preferably, the caps are molded and integrate (in one piece) said sleeve (or insert) allowing their attachment central on the tube plate.
  • exchanger 1 consists essentially in a body 2 delimiting a cylindrical cavity 3 of longitudinal axis 4, a bundle 5 of tubes 6 extending into the cavity 3, parallel to the axis 4, and of which the ends are attached to two tubular plates 7, 8, and two caps 9 and 10 of connection.
  • the invention is particularly suitable for oil coolers, water coolers, fuel, air equipping the engines of boats or trucks, the gearboxes, inverters, reducers, compressors, hydraulic units ..., and in which the cold source is freshwater or seawater; the water enters according to the arrow 11 in the cap 10, circulates in the tubes 6 and is collected at the outlet of these in the cap 9 for its evacuation according to the arrow 12.
  • the body 2 has an internal face 13 cylindrical of circular section and axis 4; at each longitudinal end of the body 2, a chamfer 14, 15 extends the unmachined cylindrical face 13 to facilitate the introduction into the cavity of a tubular plate equipped with an O-ring peripheral as marked 16, 17 figure 3.
  • the wall 20, 33 of the body 2 is radially pierced with two orifices 18, 19 respectively allowing the inlet (arrow 13) and the outlet (arrow 14) of the fluid to cool.
  • the transverse profile of the external face 21 of the wall 20 consists of a plurality of rectilinear segments: segments such as those marked 22 and 23 correspond to a longitudinal groove 24; segment 25 extending between the grooves 24 corresponds to a rib whose tail profile dovetail can be used to cooperate with a hook (shown in FIG. complementary shape for fixing the body of the exchanger to a support; the segments 26 to 30 correspond to a longitudinal tongue 31 likely to be breakthrough along the axis 32 for fixing the exchanger.
  • the body of FIG. 1 has a rib 33 whose thickness 34 can be close to 10 mm while the average thickness of the wall 20 is of the order of 2 to 3 mm when the body is made of aluminum alloy; this rib has the holes tapped 18, 19 of connection fitting to the circuit of the fluid to be cooled.
  • the transverse profile of the outer face 21 is essentially circular, with the exception of a protruding rib 33 in profile dovetail for fixing a fitting 36 equipped with an O-ring 37, for the connecting the body to fluid transport conduits.
  • the tubular bundle of FIGS. 4 and 5 comprises tubes 6 parallel to the axis 4 whose ends are sealingly attached in orifices 38, 39 respectively provided in the plates 7, 8; this beam has a plate intermediate tubular 40 parallel to the plates 7, 8 and provided at its periphery with two annular grooves 41, 42 each receiving an O-ring 43; the tubes 6 extend through this plate whose outer face is sealed, so that when this beam is housed in a body, the plate 40 and the joints 43 separate the cavity of the body in two parts, sealingly; this allows to cool a first second fluid circulating along the current lines marked 44 in the left part of the exchanger ( Figure 5), and allows to cool a second second fluid flowing along the current lines 45 in the right part of the exchanger, without that these fluids mix.
  • the body of the exchanger can be constituted by two sections 2a, 2b aligned end to end without being secured to each other. the other.
  • the assembly formed by the beam tubular and by the caps 9, 10 is not fixed rigidly to the body 2: the connection between this assembly and this body results from the elasticity of the O-rings 16, 17 respectively housed in the grooves 46, 47 provided at the periphery of the plates 7, 8, and which were compressed upon introduction of the beam into the cavity; this non-rigid connection allows the rotation of the body 2, along the axis 4, around the beam 5; he For this purpose, it suffices to exert a sufficient torque to overcome the friction forces of the joints 16, 17 on the inner face 13 of the wall 20 of the body 2; preferably this link also allows the translation of the body 2 along the axis 4 around the beam 5, when a force greater than the friction of the seals 16, 17 is applied to the face 13, and thanks to an axial clearance 48 provided between the end (49 Figure 3) of the body and the end 50 the corresponding cap; this connection also allows the free expansion of the body without stress on the caps.
