Definitions

  • the present invention relates to heat exchangers which can be used for cooling fluids such as the circulation liquid of heat engines.
  • the invention can be implemented in those of these exchangers which are used, either only for cooling the liquid considered above, or also for heating the air to be introduced into the passenger compartment of a vehicle.
  • bent tube heat exchangers are relatively difficult to fix and to connect to accessories.
  • the attachment, support and / or accessory retaining members can practically only be connected to the water box or to the collecting plate and, consequently, , the exchanger bundle itself is suspended and may vibrate, which is obviously harmful.
  • the present invention relates to new means which make it possible to fix the exchanger by one and the other of its ends.
  • the heat exchanger with bent tubes in which tubes forming pins are engaged by their two ends in the same collecting plate and are provided with heat sinks is characterized in that it comprises a core at least partially fitting the bend of at least one group of tubes.
  • the exchanger shown comprises successive tubes 1, respectively bent to form pins with parallel branches.
  • the ends of the tubes 1 open into a collecting plate 2 covered by a water box 3 which forms nozzles, such as 4 and 5, for the arrival, respectively the evacuation, of a fluid.
  • the tubes 1 are connected to heatsinks 6 shown in the drawing by fins, said heatsinks can however also be constituted by corrugated intermediate strips, mainly if the tubes 1 are flat.
  • the core 7 is shaped to delimit grooves 10 serving to partially fit the bend of the tubes and the members 8, 9 project from the parts of the core lying between the grooves 10 or at the end of this core.
  • the core 7 is firstly put in place then the dissipators 6 are arranged between the successive tubes so that they come to bear on the core. Finally the collector plate and then the water box are mounted.
  • the collector plate or the water box also includes fixing elements or supports, these can cooperate with the members 8, 9 of the core 7.
  • Fig. 3 illustrates a variant according to which the core 7a is put in place as previously in the fold 1a of the tubes 1 and this core cooperates with a cover 11 which fits the outer part of the fold 1a of the tubes 1 and which is connected to the core 7a.
  • the means for ensuring the connection between the core 7a and the cover 11 may be any, for example it may be screws, snap-fastening elements, glue, solder, vibration welding, etc.
  • the members, such as 9, for supporting or maintaining can either be formed by the core 7a or the cover 11.
  • the mounting method is similar to what is described above, that is to say that the core 7a is put in place before the dissipator 6.
  • Figs. 5 and 6 illustrate a development according to which the core 7b is designed to be engaged inside the bend of the tubes and the dissipators after the latter have been assembled.
  • a cover 11a is provided which envelops the bent projecting part of the tubes to be fixed to the core 7b.
  • the core 7b and the cover 11a have interlocking grooves 12 of the tubes 1 and complementary parts 13, 14, for example housings and projections ensuring the correct positioning of the core by relative to the cover and relative to the bundle tubes.
  • the core assembly, cover or even the core alone, depending on the embodiment of FIGS. 1 and 2, can be made to interest all the tubes of the heat exchanger or only a part of them.
