Definitions

  • the invention relates to a heat exchanger, in particular for motor vehicles, of the type comprising a bundle of finned tubes immobilized relative to a collector-water box assembly.
  • the seal between the ends of the tubes and the edges of the manifold holes is generally ensured by a sheet of elastomer or similar material which covers the manifold and which has collars each of which is engaged between a end of a tube and the edge of a manifold hole.
  • the immobilization means provided in document FR-A-2 560 368 make it possible to establish a rigid connection between the beam and the collector, which is thus opposed to the relative displacements mentioned previously.
  • the immobilization means require to practice notches along the longitudinal edges of the fins or else to provide aligned openings formed through them, which means that structural fins have to be used. particular.
  • the means for immobilizing the aforementioned document comprise tabs molded in one piece with the water box or with the collector, or else fingers molded in one piece with the collector, which makes it necessary to manufacture specific parts by plastic molding.
  • the object of the invention is in particular to overcome the drawbacks mentioned above.
  • the invention proposes, for this purpose, a heat exchanger of the type comprising a bundle of tubes provided with fins, in which the ends of the tubes are sealingly mounted in the holes of a manifold, on which a box is fixed. water, and in which immobilization means are provided to oppose relative movement, in particular by pivoting or twisting, of the beam relative to the collector, said immobilization means comprising at least one attached element, interposed between the harness and the collector-water box assembly, comprising a first part suitable for bearing on the manifold-water box assembly and a second part extending parallel to the direction of the tubes of the bundle and suitable for bearing on opposite longitudinal edges of a group of several fins, adjacent to the manifold, characterized in that the immobilization means comprise at least one pair of opposite elements, each of which comprises a first part in the form of a leg suitable for being fixed to the water box (28) and a second part in the form of legs s' extending parallel to the direction of the bundle tubes.
  • the heat exchanger uses at least one insert to immobilize the beam relative to the collector, it is not necessary to provide fins of particular structure or to modify the structure of the collector-water box assembly .
  • first part and the second part of each element extend in substantially parallel planes with one another and these two parts are connected by a web.
  • each element is advantageously fixed to a boss of the water box, for example by means of a screw or other similar fixing member.
  • the immobilization means comprise a plate capable of being interposed flat between the collector and the group of fins, this plate having at least one opening for the passage of tubes of the bundle and with at least two attached legs perpendicular to the plate and adapted to bear respectively on two opposite longitudinal sides of the beam.
  • the plate is adapted to bear under a peripheral rim projecting from the collector.
  • the plate is suitable for bearing under a central part of the collector, which is framed by a projecting peripheral rim.
  • the plate and the legs which depend on it are advantageously formed in one piece, either from a stamped metal sheet, or by molding of a suitable plastic.
  • the heat exchanger partially shown in FIG. 1 comprises a bundle 10 formed of a single row of aligned tubes 12, provided with planar fins 14 parallel to each other and extending perpendicular to the direction of the tubes 12.
  • the tubes 12 have, in the example, a body of oblong cross-section and have circular cylindrical ends 16. The latter are mounted in leaktight manner in the holes 18 of a manifold 20, also called "hole plate".
  • the manifold 20 has a peripheral rim 22 formed projecting and terminated by crimping lugs 24.
  • the lugs 24 are folded over the peripheral rim 26 of a water box 28 which, in the example, is formed by molding a plastic material. Sealing at the ends 16 of the tubes 12 is ensured by a sheet 30 of elastomer or similar material, which covers one face of the collector and which includes collars 32 clamped between the ends 16 of the tubes and the edges 34 of the holes in the collector .
  • the water box 28 defines with the collector 20 an internal volume 36.
  • the collector as just described so far, is of a conventional structure.
  • Another collector-water box assembly of similar structure is generally mounted at the other end of the tubes.
  • the heat exchanger comprises a single row of tubes, it can happen that the collector-water box assembly moves, by pivoting or twisting, which can cause cuts at the collars 32, whence risk of leakage of the fluid circulating in the heat exchanger.
  • the invention makes it possible to overcome these drawbacks by means of immobilization which, in the example, comprise at least one pair of opposite elements 38 arranged on either side of the collector.
  • Each of the elements 38 comprises a first part 40 in the form of a rectilinear tab and suitable for being fixed to the water box 28 by means of a screw 42 passing through the tab 40 and engaging in a boss 45 molded with the box. water.
  • the first part 40 extends in a substantially parallel direction of the tubes and it is connected to a second part 44 which extends parallel to the direction of the tubes of the bundle and which is able to bear on the longitudinal edges of a group of several fins 14, adjacent to the manifold.
  • the parts 40 and 44 are connected together by a veil 46 suitable for possibly taking support under the flange 22 of the collector 20.
  • the water box 28 thus comprises at least one pair of two opposite bosses 45, on which two elements 38 are fixed respectively.
  • the respective parts 44 of the two elements 38 come to bear on two opposite longitudinal sides 48 of the bundle.
  • the heat exchanger includes fins, a manifold and a standard type water box.
  • At least one insert 50 comprising a plate 52 of generally rectangular shape suitable for being interposed flat between the flange 22 of the manifold 20 and the group of fins, that is to say the fin closest to the collector.
  • the plate 52 has at least one opening 54, for example of generally rectangular shape, for the passage of at least one tube 12 of the bundle.
  • the insert 50 comprises at least two opposite tabs 56 attached perpendicularly to the plate 52 and adapted to bear respectively on the two opposite longitudinal sides 48 of the beam. Legs 56 thus play the same role that the parts 44 in the form of legs of the heat exchanger of FIG. 1.
  • the insert 50 is, in the example, formed in one piece from a stamped metal sheet, for example an aluminum sheet.
  • the element 50 is simply interposed for mounting between the tube bundle and the manifold.
  • the heat exchanger comprises at least one insert 60 which is similar to the element 50 in FIG. 2.
  • the insert 60 comprises a plate 62 of generally rectangular shape suitable for bearing under the collector 20, and more particularly in the central region of the latter as delimited by the peripheral rim 22.
  • the plate 62 has, in the example, three openings 64 of rectangular shape each intended to allow passage to a tube of the bundle.
  • the insert 60 further comprises two legs 66 attached perpendicularly to the plate 62 and adapted to bear respectively on the two longitudinal sides 48 of the beam.
  • the legs 66 thus play the same role as the legs 56 of the embodiment of FIG. 2.
  • the element 60 as constituted by the plate 62 and the two tabs 66, is formed in one piece by molding a plastic material. As in the case of FIG. 2, the element 60 is interposed for mounting between the last fin of the bundle and the manifold.
  • the invention thus makes it possible to produce, in a particularly simple manner, a heat exchanger in which the bundle of tubes is perfectly immobilized relative to the manifold-water box assembly. This prevents the appearance of relative movements likely to occur especially in the heat exchangers with a single row of tubes.
  • the invention applies very particularly to heat exchangers for motor vehicles, in particular to engine cooling radiators, or to passenger compartment heating radiators.
