Definitions

  • the invention relates to a heat exchanger, in particular for a motor vehicle, such as for example a radiator mounted in a coolant circuit of an internal combustion engine or in a heating or air conditioning installation of the passenger compartment. , or an air cooler mounted in a boost circuit.
  • Such an exchanger generally comprises a body or bundle of tubes and at least one fluid box which is mounted at one end of the body by means of a manifold or plate with holes and which is connected to a fluid circuit by a tubing.
  • the fluid box is most often made of plastic and is molded in one piece with its connection pipe (s) to the fluid circuit.
  • the internal surface of each tubing is defined by a molding core or spindle, which must be able to be easily extracted automatically when the fluid box is removed from the mold, so that this operation is compatible with mass production. As a result, the orientations and the shapes that can be given to these tubes are limited.
  • This patent provides, in fact, to fix by gluing two independent tubes respectively on two orifices formed through a wall of a fluid box.
  • the object of the invention is in particular to avoid these drawbacks.
  • a fluid box which can be provided with a tube whose shape and / or orientation can be any and are chosen at will.
  • the invention provides a heat exchanger, in particular for a motor vehicle, comprising a body or bundle of tubes and at least one fluid box which is mounted at one end of the body by means of a manifold or plate. with tubes and which is connected to a fluid circuit by a tube, characterized in that at least a part of the tube is formed in one piece with an extension of the manifold, which is covered by a corresponding extension of the box fluid.
  • this extension of the collector is lateral.
  • the collector generally has the form of a flat plate, it is then possible to form the tubing on a lateral extension of this plate and give the tubing the desired shape and / or orientation, while retaining the possibility of making the manifold and tubing in one simple molding operation.
  • the lateral extension of the manifold, which includes the tubing, is then covered by a corresponding lateral extension of the fluid box.
  • the tubing is formed entirely on the manifold.
  • FIG. 1 shows part of a heat exchanger of a conventional type usable in a motor vehicle, to form the cooling circuit radiator of an internal combustion engine.
  • the engine coolant flows through the radiator.
  • a radiator can be used in the heating or air conditioning installation of the vehicle, or else can be used in a boost circuit, in which case air circulates in the radiator.
  • This radiator comprises a bundle 10 of tubes 12 fitted with fins 14, a manifold 16 mounted at one end of the bundle 10 and a water or fluid box 18 mounted on this end of the bundle via the manifold 16.
  • the ends of the tubes 12 are mounted in leaktight manner in manifold holes 16 and open into the interior of the water box 18.
  • This water box 18 is fixed to the manifold 16 by any suitable means, by example by welding its peripheral rim 20 on the periphery of the collector 16, when the latter is made of plastic, or else by means of crimping lugs which are provided at the periphery of the collector and which are folded down on the peripheral rim of the water box 18, when the collector 16 is metallic.
  • the water box 18 is provided with a tube 22 for connection to a heat transfer fluid circuit, this tube can be the inlet tube or the liquid outlet tube in the exchanger.
  • this tube can be the inlet tube or the liquid outlet tube in the exchanger.
  • the tubing 22 has a bent shape as shown in the drawing, it is very difficult or even impossible to obtain it by molding in one piece with the water box 18. For this reason, the tubing 22 is produced separately and is then fixed to the water box 18, for example by welding its end to the edge of a corresponding orifice in the water box 18.
  • the invention proposes, as shown in FIG. 2, to form the tubing at least partly on the manifold.
  • the collector 26 is, as in the prior art, a flat plate comprising holes in which are mounted sealing the bundle tubes 10 and further comprises a lateral extension 28, extending in the plane of the manifold and comprising, by molding, the tubing 30 oriented parallel to the bundle tubes 10 and directed in the same direction as the tubing 22 of figure 1.
  • This tubing has a straight cylindrical shape and can be molded in one piece with the manifold 26, without any difficulty.
  • the water box 32 includes, like the manifold 26, a lateral extension 34 which covers the lateral extension 28 of the manifold, so that the tube 30 opens out inside the water box, in the internal volume defined by the lateral extension 34 of the water box and the lateral extension 28 of the collector.
  • the water box 32 can be fixed to the collector 26 by welding its peripheral rim 36 to the periphery of the collector 26, when the latter is made of plastic, or else by crimping, by means of pastes provided for the periphery of the collector and which are folded over the peripheral rim 36 of the water box, when the collector is metallic.
  • the axis 38 of the tubing is perpendicular to the plane of the manifold 26.
  • this axis can be oblique to this plane, if desired.
  • the tubing 40 is of cross section and includes an end portion 42 of straight cylindrical shape, connected to the lateral extension 28 of the manifold by a frustoconical portion 44 widening in the direction of the box water 32.
  • the axis 46 of the pipe 40 can be perpendicular to the plane of the manifold 26 or oblique with respect to this plane.
  • the invention makes it possible to give any orientation and / or any shape to a fluid inlet or outlet pipe in a fluid box of a heat exchanger, while retaining the possibility of making the box. fluid and the manifold by simple molding operations.
