Definitions

  • the invention relates to a heat exchanger with a brazed fluid box, in particular for a motor vehicle.
  • an exchanger of the type comprising a multiplicity of tubes each having an oblong section body connected to a different section end by means of a transition part, a multiplicity of spacers disposed between the tubes, as well as 'a collecting plate having a bottom crossed by the ends of the tubes and a peripheral edge for brazing a wall of a fluid box.
  • a heat exchanger of this type is described in particular in the publication of Patent FR-A-2 711 236. It can be used in particular in motor vehicles with thermal engine to constitute either an engine cooling radiator or a heating radiator of the passenger compartment.
  • the tubes of such an exchanger generally have a flattened cross section which connects to a less oblong section end, generally of oval shape or close to a circle, and this by means of a transition part which comprises the more often two opposite walls in the shape of a V. This transition part extends over an axial length or reduced height, but not negligible.
  • the spacers of such a heat exchanger are usually made in the form of corrugated fins which are arranged between the bodies of the tubes and this up to the level of the connection of the bodies of the tubes with the corresponding transition parts.
  • the peripheral edge of the collector plate is produced in the form of a simple fallen edge which is connected at right angles to the bottom and which allows the interlocking of the wall of the fluid box for the brazing of the latter with the collector plate.
  • the object of the invention is in particular to overcome the aforementioned drawbacks.
  • the peripheral edge of the collector plate forms a U-shaped groove limited by an inner wall which extends perpendicular to the bottom of the collector plate, on the side spacers, and over a height adapted to the height of the transition part, by an outer wall forming a rim and by a bottom wall connecting the inner and outer walls of the U-shaped groove, so that the latter provide between them a interval substantially equal to the thickness of the wall of the fluid box for its assembly by brazing.
  • peripheral edge of the collector plate delimits a groove for the fitting of the wall of the fluid box.
  • the peripheral edge thus forms a sort of skirt which comes to surround the free space defined between the bottom of the collector plate and the spacers.
  • the skirt thus formed extends over a height which corresponds substantially to the height of the free space provided between the bottom of the header plate and corrugated spacers.
  • the bottom wall of the U-shaped groove comes into contact with at least part of the corrugated spacers.
  • the thermal performance of the heat exchanger is thus optimized.
  • the outer wall of the U-shaped groove extends over a height at least equal to that of the inner wall. This contributes to a better fitting of the wall of the fluid box in the U-shaped groove of the manifold plate.
  • the outer wall of the U-shaped groove is extended, from place to place, by clamping lugs capable of facilitating the immobilization of the wall of the fluid box relative to the manifold plate for their assembly. by soldering.
  • the wall of the fluid box is advantageously provided with an external solder plating, which allows brazing to be carried out between the wall of the fluid box and the external wall of the U-shaped groove.
  • the wall of the fluid box is provided with an internal plating of solder, which allows a brazing to be carried out between the wall of the fluid box and the internal wall of the U-shaped groove.
  • the collector plate is provided with a solder plating on an internal face of the walls of the U-shaped groove, which allows brazing on both sides of the wall of the fluid box.
  • the tubes have a body of flattened section and a less flattened end of section, approaching the shape of an oval, so that the transition part has two opposite faces in V.
  • the heat exchanger comprises two rows of tubes arranged in pairs.
  • the ends of the tubes are connected by brazing to collars surrounding the holes in the collector plate.
  • the heat exchanger shown in Figures 1 and 2 comprises a multiplicity of tubes 10 each having a body 12 of flattened cross section connected to one end 14 of different cross section, in the example of substantially oval shape ( Figure 3), by through a transition part 16.
  • the latter has two opposite and inclined faces 18 in the form of a V.
  • Each of the inclined faces 18 connects a large face 20 of the body of the tube to a homologous face 22 of the end of the tube.
  • the tubes 10 can be produced, for example, as described in publication FR-A-2 715 216 or publication FR-A-2 715217.
  • the tubes 10 are arranged so as to form a bundle 24 comprising two rows R1 and R2 of tubes (FIG. 2), the latter being arranged in pairs by being joined together along a common generator G (FIGS. 2 and 3) so that the main axes A of the two tubes of the same pair are in line with one another ( Figure 3).
  • spacers 26 of corrugated shape forming fins are arranged between the tubes 10 between the tubes 10 between the tubes 10 between the tubes 10. These spacers extend over the entire length of the bodies 12 of the tubes and each has an end 28 which is located at the connection of the body 12 and the transition part 16. In other words, there are no corrugated spacers on the entire height, or axial length of the tubes, corresponding to the transition section.
  • the heat exchanger further comprises a collecting plate 30 having a bottom 32 of generally rectangular shape, in which are formed a multiplicity of holes 34 each surrounded by a collar 36 to receive respectively the ends 14 of the tubes 10. These ends 14 are fitted into the collars 36 so as to be assembled to the latter by brazing.
  • the collector plate 30 comprises a peripheral edge 38, to which we will return later, for the fitting and brazing of a fluid box 40.
  • the latter comprises a bottom wall 42 of generally rectangular shape connected to a continuous side wall 44 delimiting an open face of generally rectangular shape.
  • a longitudinal partition 46 which delimits two compartments 48 and 50 communicating respectively with the tubes of row R1 and the tubes of row R2.
  • the peripheral edge 38 of the collector plate 30 forms a U-shaped groove bounded by an inner wall 52 which extends perpendicular to the bottom 32 of the collector plate on the side opposite to the fluid box 40, that is to say of the side of the inserts 26.
  • the inner wall 52 extends over a height H1 adapted to the height H2 of the transition part 16. In the example, the heights H1 and H2 are substantially equal.
  • the inner wall 52 is connected to an outer wall 54 which, in the example ( Figures 1 and 2), which extends parallel to the inner wall 50 to form a rim.
  • the outer wall 54 extends over a height H3 slightly greater than the height H1 of the interior wall.
  • the inner wall 52 and the outer wall 54 are interconnected by a bottom wall 56 of substantially semi-circular section.
  • the walls 52 and 54 provide between them an interval I substantially equal to the thickness of the wall 44 of the fluid box, with a view to their connection by brazing (FIG. 2).
  • the outer wall 54 is extended, from place to place, by clamping lugs 58 (FIGS. 1 and 2) capable of exerting pressure on the side wall 44 of the fluid box so as to immobilize this fluid box relative to the collector plate 30 for their assembly by brazing.
  • the collector plate comprises a folded tab 60 (FIG. 1) which can serve, for example, as a fixing tab.
  • the peripheral edge 38 of the collector plate thus delimits a U-shaped groove which allows the interlocking and immobilization of the side wall 44 of the fluid box relative to the collector plate for their subsequent connection by brazing.
  • all the components of the heat exchanger namely the tubes 10, the spacers 26, the collecting plate 30, the fluid box 40 and the longitudinal partition 46, are metal parts, advantageously made of aluminum, intended to be linked together by soldering. It is necessary for this to provide a solder plating in appropriate places of the parts.
  • the wall 44 of the fluid box 40 is provided with an outer cladding of brazing 62, which enables brazing B to be carried out between the wall 44 of the fluid box and the external wall 54 of the U-shaped groove delimited by the peripheral edge 38.
  • the wall 44 of the fluid box is provided with an inner plating of solder 64, which allows a brazing B to be carried out between the wall 44 of the fluid box and the inner wall. 52 of the U-shaped groove delimited by the peripheral edge 38.
  • the collector plate is provided with an inner solder plating 66 which extends on an inner face of the walls 52, 54 and 56 of the U-shaped groove. This allows soldering to be carried out.
  • double B that is to say on both sides of the wall 44 of the fluid box.
  • the bottom wall 56 of the U-shaped groove bears against the ends 28 of the corrugated spacers 26, thus forming a sort of skirt, of generally rectangular outline, which circumscribes the free space E comprised between the ends 28 spacers 26 and the bottom 32 of the header plate, and which until now was occupied by a seal, generally of the foam type.
  • the tubes 10 of the bundle can be connected, either to another fluid box, or by U-bends.
  • the heat exchanger of the invention is intended very particularly to be used, either as a radiator for cooling a vehicle heat engine, or as a radiator for heating the passenger compartment of a vehicle.
  • the heat exchanger can include one or more rows of tubes.
  • the tubes can be joined or not joined.
