Definitions

  • the invention relates to a water box of a heat exchanger for a motor vehicle, this water box containing an oil radiator, to allow, essentially, to cool by the liquid circulating in the exchanger the oil which circulates in the radiator.
  • the oil radiator is placed in the water box before mounting it on the end of a bundle of tubes or a heat exchanger body, the radiator d oil being introduced into the water box through the open face thereof which will cap the end of the body or of the bundle of tubes of the exchanger.
  • the oil radiator comprises two pipes connecting to the lubricating oil circuit of the engine and / or the gearbox, these two pipes being sealed and fixed in two holes in the side wall of the water box, which have a diameter corresponding substantially to the external diameter of the pipes, for sealing reasons.
  • the water box must have a width at least substantially equal to the total size of the oil radiator in the same dimension, that is to say in general to the width of the radiator increased by the length of the pipes.
  • the water box must therefore have a relatively large width, which is much greater than the thickness, or corresponding dimension, of the tube bundles, current exchangers and which is therefore disproportionate to this dimension of the bundle.
  • the object of the invention is in particular to avoid these drawbacks.
  • It relates to a water box for a heat exchanger, which has the same dimensions and the same overall dimensions as the usual water boxes and which can however contain the same oil radiator as the wide water boxes of the technique anterior.
  • the invention therefore provides, for this purpose, a water box of a heat exchanger for motor vehicles, comprising an oil radiator with two oil inlet and outlet pipes which seal two openings of a side wall of the water box and by which the oil radiator is held and fixed in the water box, characterized in that these openings have a dimension much greater than the outside diameter of the pipes and are closed by two attached plates each of which comprises an orifice for the passage of a tube and is fixed to the edge of the corresponding opening.
  • Each opening of the side wall of the water box has a dimension or a diameter allowing the deflection of a tube of the oil radiator when the latter is introduced into the water box through the open face of the latter.
  • each tube of the oil radiator comprises an annular flange which is applied to the internal face of the aforementioned plate, and a part with an external thread, which extends on the other side of the plate and receives a tightening nut. this plate on the annular rim.
  • FIG. 1 representing a water box of the prior art, containing an oil radiator.
  • the known water box designated by the reference 10, is conventionally mounted at one end of a bundle of tubes 12, by means of a manifold or tube plate 14, and contains an oil radiator 16 of the type classic tubular.
  • This radiator 16 also shown in FIG. 3, comprises two coaxial cylindrical walls 18 and 20 of circular cross section - s, connected with sealing at their ends, and two pipes 22 arranged in the vicinity of these axial ends and opening into the annular space included between the cylindrical walls 18 and 20.
  • Each tube 22 is oriented perpendicular to the axis 24 of the radiator 16 and comprises a flange or an annular flange 26 in the immediate vicinity of the external cylindrical wall 18 of the radiator, and a cylindrical end part with external thread 28 intended to receive a nut 30.
  • the water box 10 comprises a side wall 32 pierced by two orifices in which the cylindrical end portions 28 of the pipes 22 of the radiator are engaged.
  • the annular flanges or flanges 26 of the pipes 22 are applied to the internal face of the side wall 32 of the water box with the interposition of a seal, and the nuts 30 screwed onto the ends 28 of the pipes are tightened on the external face of the side wall 32, so that the oil radiator 16 is thus maintained and fixed on the side wall 32 of the water box 10.
  • the oil radiator 16 is introduced into the water box through the open face thereof, which covers the end of the bundle of tubes 12 and includes a peripheral rim (not visible in FIG. 1) by which it can be fixed to the manifold 14.
  • the internal width L of the water box 10 must be substantially equal to the size 1 of the radiator 16 in width, constituted by the outside diameter of its outer cylindrical wall 18 and the length of the pipes. 22.
  • the width L of the water box 10 is thus much greater than the corresponding dimension d of the bundle of tubes 12 and is disproportionate with respect thereto.
  • the manifold 14 and the seals or seals cooperating with the manifold 14 and with the peripheral rim of the open face of the water box 10 necessarily have a width dimension corresponding to that of the water box 10. It is therefore leads in the prior art, when it is desired to house an oil radiator 16 inside a water box 10, to use a water box, a manifold and seals of a special type, which is disadvantageous from an economic point of view.
  • This water box 34 is mounted at the end of the bundle of tubes 12 by a conventional manifold 36, identical to that which would be used for fixing an ordinary water box not containing the oil radiator 16.
  • the water box 34 according to the invention has an internal width L ′ equal to that of a usual water box corresponding to the dimension d of the bundle of tubes 12 and not containing an oil radiator.
  • the side wall 48 of the water box 34 which is crossed by the pipes of the oil radiator, comprises two circular openings 52, one of which is shown in the right part of FIG. 4, each opening 52 being limited by a plane annular peripheral rim 54 and having a dimension sufficient to allow the deflection of a pipe 22 of the radiator 16 when the latter is introduced into the water box 34 through the open face 56 thereof, the pipes 22 then being oriented vertically upwards, then inclined obliquely towards the openings 52 as the radiator 16 is introduced into the water box, to finish in the arrangement shown in FIG. 2.
  • Each opening 52 of the water box is intended to be closed by an attached plate 58, of circular shape, the external diameter of which is substantially equal to that of the peripheral rim 54 of the opening 52.
  • Each circular plate 58 is formed with a orifice for the passage of the threaded end portion of a pipe 22 of the oil radiator.
  • the plates 58 are threaded onto the ends of the pipes 22 with the interposition of a seal.
  • the nuts 30 are screwed onto the ends of the pipes and tighten the plates 58 against the annular flanges or flanges 26 of the pipes.
  • the plates 58 are fixed at their periphery to the annular edges 54 of the openings 52, by ultrasonic welding, by gluing or any other suitable means.
  • the flanges or flanges 26 of the pipes have a diameter smaller than that of the openings 52, which makes it possible to easily place the oil radiator in a water box of normal width.
  • the fact that the oil radiator has a generally cylindrical shape also facilitates this arrangement.
  • the openings 52 of the wall of the water box have a non-circular shape and that they can extend over the top wall of the water box.
  • the largest transverse dimension of the body of the oil radiator is less than the width of the open face of the water box so that this radiator can be disposed without difficulty in the water box.
