Definitions

  • the present invention relates to heat exchangers, in particular exchangers used for cooling the circulation fluid of heat engines or for heating the passenger compartment of a motor vehicle.
  • the invention relates to those of these exchangers which comprise a bundle of tubes connected to heat sinks, for example fins in which the tubes are engaged and inflated or otherwise fixed.
  • the invention relates to those of the exchangers mentioned above in which the connection between the tubes and at least one collecting plate is ensured in a leaktight manner by sockets formed from a sheet of elastic flexible material, especially in elastomer.
  • the heat exchanger comprises two collector plates and two water boxes or only one collector plate and a water box, the tubes then being bent into a pin.
  • the invention relates to those of the exchangers defined above which are said to have two methodical passes, that is to say in which the circulation fluid traverses a first part of the bundle of tubes in one direction and one direction. and a second part of said beam in the same direction but in the opposite direction.
  • the heat exchangers to which the invention refers require the provision of at least one separating partition in the water box by delimiting the parts of the bundle necessary for the circulation of the fluid, this partition having to be tightly connected to the manifold plate or to a plate of flexible material which covers and can be arranged, either parallel to the direction of the air passing through the bundle of heatsink tubes, or perpendicular thereto; in the first case the partition is called a transverse partition and, in the second case, a longitudinal partition.
  • This partition must be able to withstand, without deformations leading to leaks, stresses due to pressure differences which arise in the chambers delimited by said partition.
  • this filling is often carried out by connecting the circuit, on the one hand, to a reservoir of liquid and, on the other hand, to a source of vacuum.
  • the presence of a groove in the water box has the effect of significantly reducing its bending moment, which causes deformation during the operation of the heat exchanger, deformation which results in leaks and a possible rupture of the bulkhead of the water box.
  • the invention solves the problem set out in the foregoing, while overcoming the drawbacks of the state of the technique.
  • the heat exchanger has at least two methodical passes comprising a bundle of tubes provided with dissipators and connected to at least one collecting plate by elastic sockets formed from a sheet comprising a seal for a water box provided with at least one separating partition, is characterized in that the ply of elastic flexible material has a cloth arranged at a distance from the bottom of the collecting plate, said cloth connecting bars so that these are brought into abutment by pivoting against the sides of the partition of the water box when said box is put in place to compress the seal causing the deformation of the fabric.
  • the heat exchanger illustrated in FIGS. 1 and 2 is of the tube bundle type, with at least two methodical passes, here two, commonly used for cooling the circulating fluid of engines. thermal or for heating the passenger compartment of a motor vehicle.
  • the exchanger comprises tubes 1 on which the heatsinks 2 are arranged.
  • the end of the tubes is engaged in at least one collecting plate, here two, 3,4, covered by water boxes 5,6.
  • the water box 5 constitutes the inlet box and is provided with at least one separating partition, here a single partition 7 arranged longitudinally which delimits two chambers 8, 9 communicating respectively with one and the other of the two rows of tubes 1.
  • this partition can be a transverse partition as defined above making it possible to delimit two compartments located from each end of the box 5 and by dividing said bundle into two parts communicating with each other by the others beam ends.
  • the water box 5 is provided with inlet and outlet pipes 10.
  • the collecting plates in particular the collecting plate 3, are coated on their side facing the water boxes 5, respectively 6, of a flexible ply 12 of elastomer, of substantially constant thickness over its entire extent. Peculiarities of the conformation of the ply 12 are described in the following and, in known manner, it delimits the sockets 13 in which the tubes 1 are forcibly engaged.
  • each collector plate 3 and 4 has collars 14.
  • the ply 12 forms a bead 15 which is arranged in a peripheral gutter 16 of the collector plate.
  • the bead 15 is intended to constitute a seal between the collector plate and a heel 17 that forms the corresponding water box when this heel is tightened by lugs 18 folded over a flange 19 of the water box.
  • At least the collector plate 3 which is connected to the water box 5 delimiting the chambers 8, 9 is preferably stiffened by sets of ribs 20, here transverse formed, for example, between each row of collars 14 such as the 'illustrates Figure 3.
  • the stiffening ribs 20, 20a turn their concavity towards the inside of the water box 5 and they leave free a flat part 21, extending in the same plane as the 'set of the bottom 21a of the collector plate.
  • the ply 12 forms, as explained in the foregoing, the sockets 13 intended to receive the tubes 1 arranged in two parallel rows.
  • the tubes 1 are of circular section, but they could, without departing from the scope of the invention, have another shape, for example an ovoid shape and, in this case, the sockets 13 likewise that the collars 14 would be correspondingly shaped.
  • Figure 4 taken along line IV-IV of Figure 3, shows that the middle part 21 of the bottom 21a which extends over the entire length of the bottom of the collector plate has a width which corresponds to the measurement separating two collars 14 and FIGS. 3 and 6 show that this part 21 is of reduced width opposite each set of ribs 20, 20a.
  • Figure 5 corresponds to the section VV of Figure 3, that is to say a part of the collector plate is finding between the collars 14 and a stiffening rib 20. At this level, the bottom 21a is flat over its entire width.
  • the ply 12 is shaped at its middle part to delimit two bars, here longitudinal 25, 26, connected together by a fabric 27 extending above the middle part 21 of the collector plate.
  • the drawing shows that the bars 25,26 protrude relative to the fabric 27 which connects them and the distance D which separates the bars 25,26 is equal to or slightly greater than the thickness E of the partition 7.
  • the drawing also shows that the fabric 27 is distant from the middle part 21 of the collector plate 3.
  • the fabric 27 is deformed as illustrated in phantom in 271 in FIG. 4, that is to say that the fabric comes to bear on the middle part 21 of the bottom 21a of the header plate.
  • the deformation of the canvas corresponds to an elongation of the latter and, consequently, it rotates the bars 25, 26 which come to occupy the positions 251, 261 illustrated in dashed lines in the figure. 4.
  • the ply 12 has, in its zone between the sockets 13 and the stiffening ribs 20, 20a of the collecting plate, bulges 28 (FIG. 5) provided on either side bars 25, 26, these bulges acting in the manner of struts.
  • FIG. 6 shows that at the level of the stiffening ribs 20, 20a the ply 12 is shaped to match these ribs, while retaining substantially the same thickness, but at this level, the bulges designated by 28a are of greater height than the bulges 28 provided at the level of the section VV of FIG. 3 and, if necessary, they are also of greater thickness, so that the lower part of the partition 7 is retained uniformly on its two sides and over all of its length and this while making the longitudinal bars 25, 26 have the same flexibility so that the pressure they exert on the sides of the partition 7 is uniform.
  • the bulges 28a are, moreover, shaped as shown in 281 to match the concave curve 23 which connects the bottom of the ribs 20,20a to the middle part 21 of the bottom 21a of the manifold plate and to act as a stop. preventing any displacement of the sheet in the transverse direction.
  • the ribs of stiffening 20b extend over the entire width of the bottom 21a of the collector plate.
  • the fabric 27 does not bear against the bottom of the concavity of the ribs 20b, but the seal is ensured in the same way between the ply 12 and the partition 7 since the fabric 27 is deformed by the same measure over its entire length and, consequently, the bars 26, 27 are applied with the same force against the sides of the partition 7.
  • the heat exchanger could, in a known manner, not comprise the collecting plate 4 and the water box 6, in this case, the tubes 1 would be constituted by tubes bent into a pin, the two ends of which would be engaged in the sockets 13 in the same manner as described in the foregoing.
