Definitions

  • the present invention relates to heat exchangers which include manifold plates provided with collars to delimit tube passages and in which the ends of the circulation tubes are engaged, connected in addition to secondary dissipators.
  • a heat exchanger of this kind is described in FR - A - 2 249 301 which illustrates manifold plates having stiffening ribs between each row of tubes, these ribs as well as a peripheral groove which may contain a flexible seal ensuring the sealing between the collecting plate and the water box which covers it.
  • the present invention relates to a new type of collector plates. It applies more particularly to radiators intended for heavy vehicles; due to their large dimensions, the thermal expansions take on a particularly large amplitude, while a strong bond of the water boxes and the side cheeks, aiming to form a rigid frame therefore not allowing the expansions, is provided to improve the content mechanics of these devices subjected in service to severe conditions and which requires a particularly long service life.
  • the collector plate for a heat exchanger with circulation tubes engaged in collars of the collector plate covered by a water box having a peripheral groove cooperating with the lower part of the water box to which it is rigidly connected to form with it a hollow beam, the collector plate being stamped and perforated to form passages of tubes delimited by collars to which are brazed tubes and between which are formed transverse grooves is characterized in that the grooves extend transversely to the internal wall delimiting the peripheral groove to achieve flexible embossing of the bottom of said manifold plate.
  • the header plate for heat exchangers has, on the one hand, a peripheral groove cooperating with the lower part of the water box to which it is connected by any means known in the industry of heat exchangers and ensuring rigidity longitudinal of the plate in addition to that provided by the box in the form of a hollow beam and, on the other hand, a part called "bottom of collector” in which are pressed and perforated the passages of tubes, provided with collars to which are brazed the tubes, and between which the transverse grooves are formed, thanks to which the collector plate can absorb differential expansions which generate detrimental stresses which should not appear in the brazed joints.
  • Fig. 1 partially illustrates a heat exchanger comprising circulation tubes 1, a collecting plate 2 and a water box 3 covering the collecting plate 2.
  • the collecting plate 2 is shaped in a known manner to delimit at its periphery a groove 4 which is intended to receive a deformable seal 5, for example made of elastomer, this seal being pressed into the bottom of the groove 4 by the lower edge 6 of the water box, edge which forms on its top a heel 7 on which a clamp 8 is folded .
  • the collector plate is shaped, for example stamped, to present collars 9 in one or more rows, these collars each delimiting a tube passage 10 in which the end of a tube 1 is engaged.
  • grooves 11 are formed transversely in the collector plate between each collar or row of collars 9.
  • the grooves are formed up to the internal wall delimiting the groove 4, ending in a rounded 11 a.
  • the drawing also shows that the grooves 11 turn their concavity towards the inside of the collecting plate, that is to say towards the water box.
  • the depth of the grooves 11 is preferably chosen to be greater than the thickness e of the plague collector but less than twice this thickness e.
  • the above grooves form a sort of embossing between each tube or row of tubes, which gives the collector plague flexibility making it possible to deform it between the tubes or row of consecutive tubes while, on the other hand, making the plate rigid. collector in the vicinity of its part which delimits the groove-shaped molding 4. In this way, the part of the collector plate which delimits the collars may undergo deformations of small amplitude due to differential expansions between the tubes without these deformations being transmitted to the part delimiting the groove-shaped molding which is, on the contrary, stiffened by the rounded end of the grooves.
  • the groove is formed in a rigid frame so that the seal 5 can be maintained under uniform pressure by the clamp 8, whatever the operating conditions of the exchanger.
  • the groove 11 is formed to lead to a wall part 4a of the groove 4 which does not have the rounded 1 but on the contrary a steeper slope, for example 60 ° from the horizontal.
  • the groove 11 is intended in the embodiment shown to contain a partition seal 5a (FIGS. 5, 6 and 7) which is intended to seal between a partition 12 formed internally by the water box 3 and the collector plate 2 when the exchanger is of the multiple pass type. More generally, the groove cooperates with a partition separating two compartments of the box.
  • the partition seal 5a is formed in one piece with the seal 5 and that it has a bulged portion 5b (FIG. 7) corresponding to the inclined edge 4a extending on each side the groove 11 1 .
  • This conformation has the effect that the underside 6 of the water box strongly deforms the seal at the level of the bulge, thereby causing it to be applied tightly both against the lower part of the water box and against the bottom of the groove 111 and the sloping wall 4a.
