Definitions

  • the invention relates to a heat exchanger of the type comprising a bundle of parallel tubes arranged in rows and having respective ends received in a collecting plate provided with holes, which are optionally surrounded by collars.
  • Such heat exchangers are used in particular in motor vehicles with an internal combustion engine to provide either cooling of the engine or heating of the passenger compartment.
  • the bundle tubes are then traversed by a fluid used for cooling the engine, while air circulates between the bundle tubes.
  • the bundle tubes have a non-circular section, in particular a flattened section of oval, elliptical or oblong type, so as to reduce the pressure drop undergone by the air flow passing through the heat exchanger and at optimize the thermal performance of the latter.
  • the collector plate also called a "hole plate”
  • the collector plate is generally produced in the form of a metal plate in which the holes and the corresponding collars are arranged.
  • the seal between each end of the tube and the corresponding collar is then obtained either by interposing a compressible seal, or by direct brazing, the tube then being provided with an easily fusible metal plating.
  • the collector plate must also include several rows of holes which are separated from each other by a given center distance within the same row and by another given center distance d 'one row to another. There is thus between two consecutive holes in the collector plate a thickness of material which, for reasons of mechanical strength of the collector plate, cannot fall below a minimum value, this minimum value being essentially essential for the realization of collars if the collector plate has them.
  • the object of the invention is in particular to overcome these drawbacks.
  • a heat exchanger of the type comprising a bundle of parallel tubes arranged in rows, the ends of which are received in a collecting plate provided with holes, possibly surrounded by collars.
  • each hole of the collector receives the respective ends of several adjacent tubes and in that the ends of tubes received in the same hole of the collector are brazed directly in this hole.
  • the center distance or not of the tubes can be brought to a minimum value. It is thus possible to optimize the performance of the heat exchanger and this for minimum dimensions of the collector plate.
  • the collector plate As each hole of the collector plate receives the respective ends of several tubes and it can also be surrounded by a collar, the collector plate is thus stiffened, which results in better resistance to pressure.
  • the ends of the tubes are flattened and the section of the hole then corresponds to the union of the sections of the tubes.
  • each hole in the collector plate has a generally oblong section delimited by two parallel sides and two sides in a semicircle.
  • the invention applies in particular to a collector plate whose holes are provided with collars.
  • the heat exchanger comprises a metal collecting plate 70 of generally rectangular shape comprising a core 72 limited by two longitudinal edges 74 (FIG. 2). Each of them comprises a part 76 which extends at right angles to the plane of the core 72, a part 78 which extends perpendicular to the part 76 and a part 80 which extends perpendicular to the part 78 and the free edge of which forms foldable legs 82.
  • the core 72 provides a multiplicity of elongated holes 84 of oblong shape, the largest dimension of which extends perpendicular to the two long sides of the collector plate.
  • Each of the holes 84 is surrounded by a collar 86 of oblong shape delimited by two parallel straight edges 88 and two semi-circular edges 90 (FIG. 3).
  • the holes 84 are spaced two by two from an axis E and each hole 84 is designed to receive the respective ends 92 of two joined tubes 94 belonging to two adjacent rows.
  • the tubes 94 are flat tubes whose section is defined by two parallel flat edges joined together by two rounded semi-circular edges ( Figure 2).
  • the two adjacent tubes 94 are separated from one another by a pitch P (FIGS. 2 and 3).
  • the ends 92 of the tubes 94 are slightly deformed so that each end is limited by two parallel flat edges 96, a semi-circular edge 98 and a small flat edge 100 ( Figures 3 and 4).
  • the tubes 94 are metallic and provided with an easily fusible plating to allow the brazing of two ends 92 each time in the collar 86 of a hole 84.
  • the hole 84 has a spout 116 which is produced on the collar 96 and which is able to adapt to the shape of the two rounded edges 114 of the tubes 94.
  • the hole 84 has two spouts 116 in screw vis-à-vis, which are projecting from the two edges 88 of the collar 86 to thereby fill the space formed between the ends 92 of the two adjacent tubes 94.
  • the other end of the bundle is advantageously provided with a similar collecting plate.
