Definitions

  • the invention relates to a heat exchanger, in especially for a motor vehicle.
  • a heat exchanger of this type includes a bundle of finned tubes and at least one water box having an open face capable of cooperating with a collector carried by the bundle of finned tubes, said water box containing a two-way oil radiator oil inlet and outlet pipes which pass through sealing a side wall of the water box and which the oil cooler is maintained and fixed in the water box.
  • the two oil radiator pipes are connected to a oil circuit, such as the lubricating oil circuit the motor and / or the gearbox of the motor vehicle.
  • the oil circulating in the oil exchanger is thus cooled by the liquid circulating in the heat exchanger and which is usually used to cool the vehicle engine automobile.
  • the oil radiator is introduced through the open face of the water box, before mounting it on the end of a bundle of tubes or a heat exchanger body which will be capped by the face opened.
  • the oil cooler usually includes a body cylindrical composed of two concentric tubes closed at their ends and to which the two pipes connect oil inlet and outlet, these two pipes having directions parallel to each other and perpendicular to the longitudinal direction of the radiator body.
  • Each of these tubes includes a base brazed to the cylindrical body of the oil cooler and a threaded part which, by means of a nut, makes it possible to fix the radiator oil on the side wall of the water box with interposition a seal.
  • the water box has a internal width at least equal to the total size of the oil radiator in the same dimension, i.e. the overall dimensions of the oil radiator, pipes included.
  • the interior width of the box water must be at least equal to the diameter of the cylindrical body of the oil radiator increased by the length of the pipes.
  • the water box must therefore have an internal width relatively large, which is significantly higher than the thickness, or corresponding dimension, of the beams tubes or bodies of current heat exchangers and which is therefore disproportionate to this dimension of the harness or exchanger body.
  • Each of the two openings can then be closed by a insert plate comprising at least one orifice in which is closely engaged a tubing, this plate being then fixed on the edge of the opening.
  • the invention comes to propose another simpler solution.
  • a heat exchanger of the type described in EP-A-0 196 257, which comprises, opposite to the side wall, a curved wall defining a cavity inner length at least equal to that of the radiator oil and suitable for ensuring sufficient clearance width for the installation of the oil radiator by inside the water box, and which has, at the interior cavity, an interior width greater than the overall dimensions of the oil radiator and, at the level of the open face, an interior width less than this overall dimensions.
  • the invention thus makes it possible to use collectors and standard seals, while avoiding installation place of added plates.
  • the oil radiator is pivoted by a movement combined with translation and rotation, so that the body of the oil cooler reaches the bottom of the cavity and that the two radiator connection pipes oil are located in the axis of the openings of the face lateral.
  • the curved wall extends over the entire length of the water box.
  • This curved wall is advantageously of general shape cylindrical circular.
  • the radiator of oil has a circular cylindrical body
  • the radius inside of the curved wall is greater than the outside radius from the oil cooler body.
  • the cylindrical shape of the curved wall advantageously extends over an angular sector between 120 and 190 °.
  • the wall curved connects to a connecting wall which extends parallel to the front wall and which leads to a peripheral bead delimiting the open face.
  • the water box is provided internally ribs to facilitate the positioning of oil cooler pipes to openings formed in the side wall.
  • These ribs are advantageously made transverse and each formed in a vault connecting the side wall and the curved wall.
  • FIGs 1 and 3 show a water box 10 of a heat exchanger, such as a cooling radiator of motor vehicle.
  • the water box 10 is conventionally mounted at one end of a bundle of tubes 12 with fins 14, by means of a collector or plate with tubes 16.
  • the manifold 16 is mounted, via a seal 18, on a peripheral bead 20 of the water box 10 which delimits an open face 22 of the latter ( Figure 3).
  • the water box 10 contains an oil radiator 24 of the type classic tubular, which is also shown in figure 2.
  • the radiator 24 comprises a tubular body 26 formed of two coaxial cylindrical walls 28 and 30 connected to sealing at their ends 32, as well as two pipes 34 arranged in the vicinity of these axial ends and opening out in the annular space between the walls cylindrical 28 and 30.
  • Each tube 34 is oriented perpendicular to the axis 36 of the tubular body 26 and it includes a base 38 brazed on the outer wall 30 and a threaded part 40 which, by means of a nut 42 (FIGS. 1 and 3) allows the oil radiator 24 to be fixed to a wall lateral 44 of the water box with interposition of a seal seal 46 ( Figure 3).
  • the side wall 44 is pierced with two orifices 48 in which are engaged respectively the threaded parts 40 of the pipes 34.
  • the bases 38 of the pipes 34 are applied against the internal face of the side wall 44 with interposition of the seal 46, and the nuts 42 screwed onto the threaded parts 40 of the pipes are tight against the external face of the wall 44, so that the oil cooler 24 is held and fixed on the wall side 44 of the water box 10.
  • the two pipes 34 can then be connected, by through two male fittings (not shown) to a oil circuit.
  • the oil radiator 24 has a space requirement in width l (figure 2) which corresponds to the diameter of the tubular body 26 increased the length of the pipes 34.
  • the open face of the water box has an internal width at least equal to the overall dimensions in width of the oil cooler to allow introduction of the latter in the water box, unless required, as in document EP-A-0 196 257, plates reported.
  • the invention proposes another solution which makes it possible to use a water box whose open face has a width reduced and which does not require the use of plates reported.
  • the water box 10 comprises, at opposite the side wall 44, a curved wall 50 which turns its concavity towards the inside of the water box and which thus defines an interior cavity 52 which extends over a length at least equal to that of the oil radiator which is intended to be received in the water box.
  • the curved wall 50 is connected to the wall 44 by a wall upper 56 forming an arch, which connects perpendicularly to wall 44.
  • the curved wall 50 can extend, either only over a length at least equal to that of the oil radiator, i.e. over the entire length of the water box.
  • the curved wall 50 has a generally circular cylindrical shape whose radius R ( Figure 4A) is greater than the radius outside of the tubular body 26 of the oil radiator 24.
  • cylindrical shape of the curved wall 50 extends over an angular sector A (FIG. 4A) which is advantageously between 120 and 180 °.
  • the curved wall 50 is connected to the bead 20 by a connecting wall 58 which extends parallel to the side wall 44 and which leads to the peripheral bead 20.
  • the water box 10 has, at the level of the internal cavity 52 (in the axis 62 of the holes 48 receiving the pipes 34) an interior width L1 greater to the overall dimensions largeur of the oil radiator 24 and it has, at the open connection face 22, an interior width L2 which is less than the overall width l.
  • the water box 10 is internally provided with ribs 60 facilitating, as we will see later, the positioning of oil cooler pipes to ports 48 formed in the side wall 44.
  • These ribs are made transverse and formed in the upper wall 56, forming an arch, connecting the side wall 44 and the curved wall 50.
  • ribs 60 facilitate positioning tubes 34 with respect to the holes 48 formed on the vault of the water box.
  • the invention thus allows the use of a water box whose interior width L2 at its open face is equal to that of conventional water boxes containing no oil cooler.
  • the oil cooled by the oil radiator contained in the water box can be part of the lubrication circuit of the motor and / or gearbox of a motor vehicle.
