Definitions

  • the invention relates to a heat exchanger with a brazed fluid box, in particular for a motor vehicle.
  • a heat exchanger of the type comprising a collecting plate provided with a bottom suitable for being connected to a bundle of tubes, as well as a fluid box terminated by a peripheral edge suitable for engaging in a peripheral rim of the header plate for their connection by brazing.
  • brazing is generally provided by a thin plating provided on the manifold plate and / or the fluid box, it is necessary that the edge of the fluid box and the edge of the manifold plate are in surface contact over the entire periphery.
  • the collector plate is provided with a deep-drawn groove in which the edge of the fluid box is engaged.
  • This solution facilitates obtaining a reduced clearance suitable for guaranteeing a tight brazing between the fluid box and the manifold plate, and this whatever the deformations presented by the fluid box before its introduction into the manifold plate, or whatever that the deformations caused by heating up to the brazing temperature are.
  • Another known solution consists in using a collecting plate in the form of a bowl in which the edge of the fluid box is engaged.
  • this solution does not guarantee the maintenance of a tight brazing game between the edge of the fluid box and the edge of the manifold plate.
  • a heat exchanger of a different type that is to say with mechanical assembly, in which projections are provided on a collecting plate to guide the edge of a water box so that it comes to compress the edge of a sealing body, without this sealing body being able to be damaged.
  • the protrusions here are intended to guide the edge of the water box so that it comes to compress the edge of the sealing body, in the region where the edge of the sealing body is located, that is to say in a peripheral groove of the collector plate.
  • the object of the invention is in particular to overcome the aforementioned drawbacks.
  • each stamped projection comprises at least one generator which extends in a direction substantially parallel to the peripheral rim of the collector plate and which is located at a distance therefrom, substantially equal, by greater value, than the thickness of the peripheral edge of the fluid box.
  • each stamped projection is produced in the form of a spike of generally circular cylindrical shape with parallel generatrices.
  • each projection is produced in the form of a dome.
  • the invention applies in particular to a heat exchanger of the type defined above, in which the bottom of the collector plate comprises a multiplicity of holes each surrounded by an internal boss for the reception of one end of the tube.
  • the projections are then advantageously provided between two adjacent internal bosses.
  • the bottom of the collector plate of such a heat exchanger usually comprises external bosses each disposed between two adjacent internal bosses.
  • the projections are then advantageously each located in the axis of an external boss.
  • the invention applies in particular to a heat exchanger in which the collector plate has a substantially rectangular shape and is delimited by two longitudinal sides and two transverse sides.
  • the projections are advantageously provided along the longitudinal sides. It is generally not necessary to provide protrusions along the transverse sides.
  • the rim of the manifold plate has one end which is crimped locally against the fluid box to provide temporary support for soldering.
  • the manifold plate and the fluid box are both formed of aluminum or aluminum alloy.
  • FIG. 1 partially represents, in top view, a collecting plate 10 intended to form part of a heat exchanger according to the invention.
  • the collector plate 10 is made of a metallic material, for example aluminum or an aluminum alloy.
  • the collecting plate 10 has a bowl-type shape and it comprises a generally flat bottom 12, of rectangular shape, bordered by a peripheral rim 14, which comprises two longitudinal sides 16 parallel to one another and two transverse sides 18, parallel to each other, of which only one is visible in FIG. 1.
  • the sides 16 and 18 are interconnected by rounded parts 20 in the form of quarter circles.
  • the collector plate 10 comprises a tab 22 which extends beyond one of the transverse sides 18 to serve, for example, as a retaining tab.
  • each of the holes 24 is bordered by an internal boss 30 of shape homologous to that of the hole and projecting from the side of the peripheral rim 14, as can be seen in FIGS. 2 to 4. In other words, each of the bosses 30 is arranged with the side of the fluid box, which will be discussed later.
  • the presence of the internal bosses 30 facilitates better surface contact between the collector plate 10 and the tubes 28 with a view to their connection by brazing.
  • the bottom 12 of the collector plate 10 further comprises external bosses 31 (FIGS. 1 to 4) each disposed between two adjacent internal bosses 30.
  • the external bosses 31 are oblong in shape and are directed on the side opposite to the fluid box. Their main function is to strengthen the bottom of the collecting plate.
  • the bottom 12 of the collector plate comprises a multiplicity of stamped projections 32 arranged in two lines parallel respectively to the two longitudinal sides 16 of the peripheral rim 14 (FIG. 1).
  • each of the projections 32 forms a boss which extends on the same side as the flange 14, that is to say on the side of the boss 30, therefore on the side opposite to the boss 31.
  • each of the projections 32 has the shape of a substantially hemispherical dome.
  • Each of the projections 32 is arranged between two adjacent internal bosses 30 and in the axis of an external boss 31.
  • each projection 32 (FIG. 1) is located at a determined distance d from the peripheral rim 14, that is to say with respect to the internal face of a longitudinal side 16.
  • the fluid box 38 is made of metallic material, advantageously of aluminum or of aluminum alloy, and it comprises a wall 40 provided with reinforcing ribs 42, in the shape of a U, as shown in FIGS. 2 and 3.
  • the wall 40 is connected to the peripheral edge 36 via a shoulder 44 ( Figures 3 and 4).
  • the peripheral edge 36 has a rectangular outline with rounded corners which corresponds to that of the peripheral edge 14 of the collector plate, with a view to their fitting together, as shown in Figures 3 and 4.
  • the heat exchanger of the invention is manufactured as follows.
  • the tubes 28 and their spacers are first assembled with the collecting plate 10. Then, the fluid box 38 is assembled with the collecting plate 10.
  • peripheral edge 36 of the fluid box is introduced into the peripheral rim 14 of the manifold plate. Because the edge 36 and the rim 14 have homologous shapes, they fit closely together.
  • the edge 36 of the manifold is guided by the projections 32, which ensures close contact between the edge 36 and the flange 14 for their subsequent connection by soldering.
  • the flange 14 is locally deformed at its end (FIG. 4) to form crimping points which bear against the shoulder 44. These crimps are made of place in place on the perimeter, preferably only at the two longitudinal sides.
  • the brazing is carried out by passing the heat exchanger through a suitable furnace which causes the brazing alloy which has been previously plated on the constituent elements of the heat exchanger to melt.
  • the heat exchanger of Figures 5 and 6 is similar to that of Figures 1 to 4, except as regards the shape of the stamped projections formed in the bottom of the collector plate.
  • each projection 34 comprises stamped projections 34 placed in the same places as the projections 32 of the shape of previous achievement.
  • these projections 34 are each produced in the form of a spike of generally circular cylindrical shape with parallel generatrices.
  • each projection 34 comprises at least one generator G (FIG. 6) extending in a direction substantially parallel to the peripheral rim 14 of the collector plate and located at a distance d from the latter which corresponds to the distance d from the Figure 1. In other words, this distance is substantially equal, by greater value, to the thickness of the peripheral edge 36 of the fluid box.
  • the invention applies very particularly to the production of heat exchangers which can be used as cooling radiators for motor vehicles.
