Definitions
- the present invention relates to improvements made to shell and tube multitubular heat exchangers and methods of making these 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 defined cylindrical cavity by a hollow body (or calender) in which the bundle of tubes extends; typical applications: heat exchangers for heat engines, reducers, inverters, compressors, hydraulic units ...; in this type of known exchanger, the transfer of thermal energy between the hot source and the cold source takes place in particular by conduction through the wall of the tubes; in order to get a transfer flow sufficient energy (and / or heat exchange coefficient), the tubes are made made of a material having a high thermal conductivity, such as a metal alloy with based on copper, aluminum, nickel, titanium or stainless steels.
- the invention applies in particular to such exchangers comprising two tubular plates in the general shape of a disc, which are pierced with a plurality orifices, 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 to this plate, in particular by brazing, welding or swaging.
- the tube bundle generally comprises, in addition to the tubes and the plates end tubes, baffles for guiding the flow of the second fluid inside the hollow body; these baffles are generally essentially formed by thin plates extending transversely to the tubes and parallel to the end tubular plates, are evenly spaced along tubes and close part of the cross section - generally circular - of the hollow body, to guide the second fluid.
- Such exchangers generally also comprise, at each of its two longitudinal ends, a cap (water box) respectively covering a said tubular plates, and allowing either the connection of the exchanger to two conduits (external to the exchanger) for transporting the first fluid, i.e. guiding this fluid in the case of a "blind" cap, ie devoid of connection to a external duct.
- the hollow body is provided with an opening for the entry of the second fluid into said cavity as well as an outlet for this fluid;
- the hollow body is generally consisting of a generally tubular part 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 fasteners - allowing to be joined to the body, in a sealed manner, at least one of the tubular plates as well as the two caps.
- the body of the small exchangers are generally manufactured by molding (without pressure) of a metal alloy, the body and the flanges being molded in one piece; this technique has drawbacks: the face internal body must be machined over its entire length to exhibit roughness and a geometric quality compatible with the use made of it; the faces flanges must also be raised; these molded parts frequently have defects in their mass resulting in porosity incompatible with the waterproof wall function which they must fulfill; moreover, these faults can only be validly checked after mechanical machining (boring, turning ...); it is thus necessary to discard expensive parts; the pressureless molding technique (in sand molds) further prevents to make thin walls.
- An object of the invention is to propose such exchangers which are improved, as well as a manufacturing process of these exchangers which allow reduce the cost.
- the invention consists of a process for manufacturing such exchangers, in which a blank is produced by extruding a material to form a hollow section, then from which a section of said section is cut profiled; this process makes it possible to obtain a blank defining a cylindrical cavity of generally circular section whose geometry and surface condition are good enough to avoid the need for subsequent machining of the internal face of the wall of the body even when the end of this wall forms a scope for seals; using a homogeneous material and thanks to the pressurization of the material allowing its passage through the die, a blank is obtained free of faults (micro cavities), and therefore non-porous.
- the invention consists in proposing such exchangers whose the hollow body essentially consists of one or more sections of profile extrusion molded, and has no 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 can include at least one rectilinear segment which is tangent to a first circle concentric with a second circle corresponding to the transverse profile of the internal face of the wall and / or of the body; to this straight segment of the external profile corresponds to a flat part of the external face of the hollow body; this flat face thus preferably extends tangentially to a cylinder coaxial with the hollow body, in a part of the wall of the body which has said inlet and outlet openings 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 planar face, has a thickness greater than the average thickness of the tubular wall of the body; this results in a large rib (or longitudinal boss) which facilitates the production of said orifices under form of tapped holes suitable for receiving
- the transverse external profile of the body may preferably include other rectilinear segments, to which projecting ribs (or many hollow grooves) formed on the external 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 the attachment of connection connector of the transport conduits of the second fluid (Figure 9).
- the exchangers according to the invention do not include rigid connection means between the hollow body and the tube bundle, the mechanical connection between these elements essentially resulting from the contact (support) forces acting between these two parts via two first sealing members such as two seals toric, which are flattened (compressed) between two cylindrical bearing faces (or litters) provided respectively on each of these two parts; in the absence of these sealing members, the beam can freely slide in the body cavity; in the presence of these sealing members the bundle can slide in the cavity under the action of sufficient effort, in particular under the action of lengthening the bundle tubes, due to their thermal expansion; each of said organs sealing is generally housed in an annular groove; preferably these grooves are provided on the external face of the tubular plates; this avoids the making (more expensive) grooves on the internal face of the wall of the hollow body; this then only requires the production of a chamfer at its end (s) internal (s), which allows to introduce by sliding a beam whose plate tubular is provided with the seal without damaging this seal and facilitating its crushing.
- each cap is respectively fixed to one or the other of the plates tubular of the bundle, thanks to a first rigid connection means provided in part central of the external face of the plate, such as a tapped hole, and by means guide and support which is provided in the central part of the cap, such as a sleeve (or insert), which is capable of receiving a second rigid connection means - such as a screw - complementary to said first rigid connection means.
- a second annular sealing member which is preferably resting (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 coaxial and facing each other; 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 an engagement of these joint bearing surfaces (bearing) with the joint to form a tight assembly, in exerting a relatively weak effort which can result from mutual engagement said rigid connection means provided in the central part of the cap and of the plate, in particular by screwing a single screw; these efforts are much less than those to be exercised to ensure a tight connection by a crushed O-ring between two parallel flat bearing faces, as is the case with flange connections.
- each of said two plates tubular end comprises a groove receiving said first sealing member with the hollow body, and has a counterbore opening on its external 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 tubular plates and is less than the distance separating the two counterbores; therefore, the first sealing members are (after mounting) arranged set back from the ends of the body and the second sealing members are arranged beyond the ends of the body, that is to say outside of it; he follows that in the event of a defect in one of these sealing members producing a leak of either of the two fluids, the leakage current flows outside the body and is therefore identifiable; furthermore, no mixture of these two fluids can result from such a default.
- the sealing means between the tube plate and the cap allows to use, for the realization of the cap, a resistance material medium and thin mechanical, such as plastic if necessary reinforced with mineral fibers: preferably, the caps are molded and integrate (in one piece) said socket (or insert) allowing their fixing central on the tube plate.
- Figure 1 illustrates in end view a section of extruded profile forming a exchanger body according to the invention.
- FIG. 2 is a view in partial longitudinal section of the body of FIG. 1.
- FIG. 3 is a view in longitudinal section of an exchanger according to the invention, which is equipped with two caps of axial (longitudinal) orientation; in this figure, the bundle tubes are not shown to facilitate understanding.
- FIG. 4 is an end view of the tube bundle of FIG. 5.
- FIG. 5 illustrates in longitudinal section view a multitubular bundle of a exchanger according to the invention which comprises a body in two separate parts and which allows a heat exchange between a first fluid and two second fluids; for this purpose the beam is equipped with an intermediate tubular plate disposed between the two end tubular plates and comprising two grooves intended to receive two seals for sealing with each of the body portions.
- FIGS. 6 and 7 respectively illustrate a view in longitudinal section and in end view, an embodiment of a cap of an exchanger according to the invention
- Figure 6 is a view along IV-IV of Figure 7 which is itself a view along VII in Figure 6.
- This example shows the possibility of integrating other elements such as drain plug, zinc anode, thanks to the presence of a radial hole 200.
- Figure 8 schematically illustrates in longitudinal section view a cap angled exchanger according to the invention.
- Figure 9 illustrates in schematic cross-sectional view a mode of connection of body inlet and outlet ports to conduits external.
- Figure 10 illustrates in end view the attachment of an exchanger by two 80 angled L-shaped legs and one end of which forms a hook taken in a groove of the body.
- the exchanger 1 consists essentially in a body 2 delimiting a cylindrical cavity 3 with a longitudinal axis 4, a bundle 5 of tubes 6 extending in the cavity 3, parallel to the axis 4, and of which the ends are fixed to two tubular plates 7, 8, and two caps 9 and 10 of connection.
- the invention is particularly suitable for oil, water, fuel, air fitted to boat or truck engines, gearboxes, inverters, reducers, compressors, hydraulic units ..., and in which the cold source is fresh water or sea water; water enters according to 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 arrow 12.
- the body 2 has an internal face 13 cylindrical with circular section and axis 4; at each longitudinal end of the body 2, a chamfer 14, 15 extends the cylindrical face 13 not machined to facilitate the introduction into the cavity of a tubular plate fitted with an O-ring peripheral as marked 16, 17 figure 3.
- the wall 20, 33 of the body 2 is pierced radially by two orifices 18, 19 allowing respectively the entry (arrow 13) and the exit (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 Figure 10) of complementary form for fixing the body of the exchanger to a support; the segments 26 to 30 correspond to a longitudinal tongue 31 capable of being drilled along axis 32 for fixing the exchanger.
- the body of Figure 1 has a rib 33 whose thickness 34 can be close to 10 mm while the average thickness 35 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 threaded threads 18, 19 for fixing the connection to the circuit of the fluid to be cooled.
- the transverse profile of the external face 21 is essentially circular, except for a prominent rib 33 with a profile in dovetail for fixing a fitting 36 fitted with an O-ring 37, for connection of the body to fluid transport conduits.
- the tubular bundle of FIGS. 4 and 5 comprises tubes 6 parallel to the axis 4, the ends of which are tightly fixed in holes 38, 39 respectively provided in 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; tubes 6 extend through this plate, their external face of which is tightly secured, so that when this beam is housed in a body, the plate 40 and the seals 43 separate the body cavity into two parts, tightly; this allows to cool a first second fluid flowing along the current lines marked 44 in the left side of the exchanger ( Figure 5), and allows to cool a second second fluid circulating along the current lines 45 in the right part of the exchanger, without that these fluids mix.
- the body of the exchanger can be consisting of two sections 2a, 2b aligned end to end without being secured one to the other.
- the assembly constituted by the beam tubular and by the caps 9, 10 is not rigidly fixed to the body 2: the connection mechanical 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 during the introduction of the beam into the cavity; this non-rigid connection allows rotation of the body 2, along the axis 4, around the beam 5; he it suffices for this purpose to exert a sufficient torque to overcome the friction forces of the seals 16, 17 on the internal 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 is exerted greater than the friction of the seals 16, 17 on the face 13, and thanks to an axial clearance 48 provided between the end (49 FIG. 3) of the body and the end 50 the corresponding cap; this connection also allows the body to expand freely without constraint on the caps.
- each of the tubular plates 7, 8, 40 is in the form of a thick disc whose edge receives the seals.
- each plate 7, 8 projects outside the body; this external part of the plate 7, 8 has a counterbore annular peripheral 53, 54 opening onto the respective external face 55, 56 of plates 7, 8; each counterbore receives an O-ring 57, 58 ensuring sealing (by radial support) between the periphery of the plate and the cylindrical end piece 59, 60 caps 9, 10; each of these end pieces is provided with a chamfer 61 (FIG. 6) for avoid damaging the seal when tight fitting the nozzle around the plate tubular fitted with seal.
- Each cap has a flared wall 62 extending the end piece 59, 60 and extended by a second cylindrical end piece 63 for connection to a non-duct represented.
- the cap 9 has in the central part a wall 162 flared and angled which connects the connecting piece 163 (to a conduit inclined with respect to the axis 4) at the end piece 59 for connection with the tube plate; sealing can be ensured by a seal provided under the head of the screw.
- each cap on the respective tube plate is obtained by a screw extending along the axis 4 through a cylindrical sleeve 65 axis 4 integrated into the cap and on which the head 64 of the screw bears; the screw is screwed in a tapped hole 66 provided in the center of each plate 7, 8, and leading to the external face thereof only.
- Figure 7 illustrates three radial arms 68 arranged at 120 degrees around the axis 4, which connect the central sleeve 65 to the flared wall 62 of the cap; the number and the shape of the arms (sails) is adapted to the diameter and the stressing forces of the cap.
- the fixing screw is embedded in the fluid circulating in the cap.
- the thin link arms 68 extend substantially radially with respect to to axis 4 along which extend the connection sleeve 63 and the sleeve cylindrical 65.
- the tube bundle includes baffles 69 annular disc-shaped, pierced in the middle for the central passage fluid 44, which are alternated with baffles 70 in the form of discs without holes in the middle and of smaller diameter than that of the baffles 69 for the passage of the fluid between the periphery of the baffles 70 and the wall 13 of the body 2; the diameter exterior of baffles 69 is adjusted to limit leakage by circulation between their periphery and the wall 13 of the body 2.
