Definitions

  • the invention relates to heat exchangers, especially for a motor vehicle.
  • a header for a brazed heat exchanger comprising walls which define a chamber, one of the walls of the chamber being provided with an opening, a pipe being connected to this opening.
  • the collector plate which is also called a perforated plate, has a multiplicity of holes in which the tube ends which constitute the heat exchanger bundle are received. To these tubes are associated fins contributing to increase the heat exchange surface.
  • the collector plate is formed by a wall which delimits a chamber communicating with the tubes to allow the circulation of a heat transfer fluid in the beam.
  • One of the walls of the chamber is provided with at least one tubing to allow the entry or exit of the coolant.
  • Brazed heat exchangers comprise a bundle mounted between two manifolds.
  • the beam is formed of a multiplicity of tubes arranged parallel to each other and alternating with spacers.
  • These spacers are of corrugated type, that is to say that they are formed from a deformed metal strip to form corrugations.
  • a spacer disposed between two adjacent tubes comes into respective contact with the two tubes by end regions of the corrugations.
  • the heat exchanger further comprises two cheeks, also called sleepers, which frame the beam and are arranged parallel to the tubes.
  • the different parts are formed of a metal material externally coated with a solder alloy.
  • the different parts of the exchanger are brazed by passing through an oven. It is therefore necessary to temporarily hold them in place so that they can not move each other during their passage in the oven before being permanently joined together. In particular, it is necessary that the pipes do not move relative to the wall of the chamber.
  • the present invention aims to provide a manifold, and a heat exchanger comprising such a box, which allow rapid and inexpensive temporary fixation of the tubing in an opening of a wall of the manifold.
  • the tubing is introduced manually or automatically into the opening, the lug or lugs being placed opposite the corresponding notches made at the periphery of the opening. Then the tubular is angularly rotated by a certain angle so that the lug or the lugs are no longer facing the notches. Thus the tubing is temporarily maintained on the manifold box stably during the passage of the exchanger in the oven.
  • the tubing comprises at least two lugs.
  • the tubing comprises three lugs arranged at 120 ° from each other.
  • the opening will then also include three notches arranged at 120 ° from each other.
  • the number of notches is equal to the number of lugs of the tubing, but this characteristic is not essential.
  • the number of notches can also be a multiple of the number of lugs.
  • the opening has six notches arranged at 60 ° from one another, which would limit the angle of rotation required to introduce the lugs in the notches.
  • the tubing is bent and must extend in a given direction to be fitted with a flexible conduit. In this case, it is necessary to respect a precise angular orientation of the tubing with respect to the manifold. If the tubing is mounted manually, the wall of the chamber which has the opening is preferably provided with a stop which limits the rotation of the tubing by cooperation with a pin.
  • the manifold comprises a first portion 10 and a second portion 12, each formed from a metal sheet, preferably aluminum, which is shaped by conventional cutting and stamping operations.
  • the first part 10 has a bottom 14 which is generally flat and of elongated rectangular shape.
  • This bottom 14 is intended to form the collector plate, also called “plate with holes", of the manifold.
  • This bottom comprises for this purpose a plurality of spaced holes 16 of elongate shape for receiving tubes 18 forming part of the beam of the heat exchanger. In the example described, these are flat tubes 18 between which fins 20 are arranged in the form of corrugated inserts.
  • the portion 10 further comprises two lateral flanks 22 folded facing each other, and which are generally planar and parallel to each other. These flanks are connected substantially perpendicular to the bottom 14 by two fold lines 24 which are parallel to each other.
  • the lateral flanks 22 comprise in their central part respective extensions 26 and 28.
  • the extension 26 has an opening 30 while the extension 28 is completely closed.
  • the opening 30 is circular in shape and is intended to allow the adaptation of a tubular 32 of circular section.
  • the second part 12 fits on the lateral flanks 22 so that these two parts jointly delimit a closed volume which communicates with the tubes 18 of the beam. It will be understood that it is thus possible to perform in a single brazing operation a heat exchanger comprising a beam formed by a multiplicity of tubes and fins, together with one or two manifolds.
  • FIG. 2 a perspective view of the respective extensions 26 and 28 of the lateral flanks 22.
  • the opening 30, formed in the extension 26 has notches 34, which are three in the embodiment shown.
  • the notches 34 are arranged at 120 ° from each other.
  • the end of the tubing 32 which engages in the opening 30 has three lugs 36, also arranged at 120 ° from each other. These lugs form protuberances protruding outwardly of the tubing.
  • the tubing 32 comprises a flange 40 which limits the penetration of the tubing into the opening 30.
  • the tubing is rotated in one direction or in the other. a certain angle, for example 10 or 20 ° (as shown by the arrow F2 on the figure 4 ), so that the lugs are no longer opposite the notches 34.
  • the pipe is thus held firmly enough on the manifold box so that it is possible to perform the brazing operation without it being possible. moves.
  • the lugs 36 are shaped such that a slight tightening of the tubing on the wall 26 is obtained.
  • the tubular 32 instead of being straight cylindrical as shown in the example, has a bent shape. In this case, it must be arranged in a precise angular orientation relative to the manifold to connect to a flexible pipe of the fluid circulation circuit. If the tubing is introduced by a robot, the robot can be adjusted to provide a proper angular orientation and no further action is necessary. If the tubing is introduced manually by an operator, the wall 26 preferably include a boss 42 ( Figures 3 and 4 ), obtained for example by punching, and forming a stop which limits the rotational movement of the tubing relative to the manifold. When one of the lugs 36 abuts against the boss 42, the appropriate angle of rotation is obtained.
  • notches 34 are small in size so that they can be filled by the solder alloy during the soldering operation.
  • FIGS 5 to 8 illustrate a variant of the heat exchanger according to the invention, in which means are provided for clamping the tubing in the final position of its rotational movement, defined by the abutment of the wall, so as to avoid an inversion of this movement.
  • FIGs 7 and 8 for clarity, only a square-shaped region of the wall, concentric with the opening, is shown.
  • the tubing 50 is bent and its end 52 which engages in the manifold here has a single lug 54, associated with a single notch 56 of the generally circular opening 58 through which the tubing.
  • a stop 60 similar to the stop 42 of the Figures 3 and 4 is formed at the edge of the opening 58, at an angular distance from the notch 56, about the axis A of the opening, slightly greater than 90 ° so as to limit the rotation of the tubing at an angle of 90 ° counterclockwise, as seen from inside the manifold, according to arrow F of the figure 8 .
  • a ramp 62 is juxtaposed to the stop 60, at an angular distance of 90 ° with respect to the notch 56.
  • the ramp 62 like the stop 60, is produced by deformation, in the direction of the axis A. of the wall 64 of the header, in which the opening 58 is formed.
  • tubing 50 has a width greater than the thickness of the wall 64, so that the tubing can rotate freely about the axis A after the lug has been engaged through the notch 56.
  • the lug comes opposite the ramp 62, which has vis-à-vis thereof a surface 70 inclined so as to move progressively away from the plane of the outer face 72 turned towards the flange 68, of the wall 64, up to a maximum distance slightly greater than the width of the gap 66 so as to effect an axial clamping of the wall 64 between the lug 54 and the flange 68, after a rotation of 90 °, while the lug 54 abuts in the circumferential direction on the stop 60, which protrudes up to a distance from the wall 72 substantially greater than the width of the gap 66.
  • a projection 74 similar to the stop 60 is made by deformation of the wall 64, in a position slightly offset relative to the notch 56 in the opposite direction to that of the rotational movement of the tubing. This projection cooperates with the lug 54 to prevent rotational movement of the tubing in the wrong direction during its manual placement.
  • clamping means comprising the ramp 62 and the keying means comprising the projection 74, although incorporated herein in the same embodiment, can be implemented independently of each other.
  • one and / or the other can be used in combination with a multiplicity of pins as described in the first embodiment.
  • the heat exchanger of the invention can be used in particular to constitute an engine cooling radiator or a heating radiator of the passenger compartment of a motor vehicle.
