Definitions

  • the present invention relates to the field of heat exchangers fitted to motor vehicles, in which liquid fluids circulating through a bundle of tubes provide heat exchange between the heat exchanger and the ambient air.
  • the present invention relates more specifically to the field of cooling radiators through which coolant fluids at different respective temperatures circulate distinctly.
  • Radiators for motor vehicles are commonly used to cool the propulsion engine of the vehicle.
  • Such a radiator is conventionally organized in a bundle of tubes interposed between two manifolds.
  • the manifolds each include a manifold and a cover assembled together.
  • the tubes are mounted on the manifolds via their axial ends which open out respectively inside one and the other of the manifolds.
  • the manifold of each of the manifolds has a series of slots aligned along the manifold.
  • the ends of the tubes pass through the slots of one and the other of the manifolds, and thus open out inside the manifolds.
  • a radiator for a motor vehicle is capable of being traversed by heat transfer fluids brought to different temperatures.
  • a radiator comprises a so-called high temperature portion and a so-called low temperature portion.
  • each of the manifolds comprises a partition separating their internal volume into two compartments through which the liquid fluid brought to different temperature circulates respectively.
  • the tube bundle then comprises two groups of tubes respectively assigned to the circulation of one and the other of the fluids at different temperatures, between the compartments of the manifolds.
  • the radiator is segmented into two heat exchange portions through which can circulate respective heat transfer fluids brought to different temperatures.
  • the radiator is subjected to temperatures which may be significantly different, thus generating a large temperature difference between the two heat exchange portions of the radiator.
  • the result is that the radiator is deformed in a disparate manner because it is subjected to thermal shocks which can be substantial. Such thermal shocks are therefore to be avoided at the risk of deforming the radiator and of degrading it more or less rapidly by formation of cracks.
  • the present invention aims to provide a structurally simple solution making it possible to close the ends of inactive tubes at a lower cost, without affecting the efficiency of the heat exchanger and improving its durability of operation.
  • Such a solution is particularly advantageous because it limits the impact of the formation of the thermal barrier on the components of the manifolds. Indeed, the structural organization as well as the methods of obtaining the manifolds and assembly of the heat exchanger are simplified in particular due to the fact that the length of the tubes used in the inactive portion is equal to the length of the tubes. tubes of the active portion.

At least two groups of slots, adjacent to one another, are each made up of so-called open slots, that is to say opening outwardly at each of the large faces of the collecting manifold plate. These slots therefore pass right through the collector plate.
  • Such open slots are dedicated to receiving one of the ends of the active tubes constituting a bundle of tubes interposed between two manifolds, thus providing fluid communication between them.
  • Such active tubes are potentially divided into two groups of active tubes which put in fluid communication separate compartments of two partitioned manifolds, in particular similar ones.
  • Such groups of active tubes open out inside the compartments of one and the other of the manifolds, being assigned to separate compartments of one and the other of these manifolds.
  • the groups of active tubes are nested inside the groups of open slots of the collector plate.
  • the respective circulations of heat transfer fluids brought to different temperatures are organized between the manifolds by means of groups of active tubes.

  • At least one so-called blind slot is suitable for receiving by interlocking the ends of a tube rendered inactive by the blind character of the slot receiving it.
  • the cap prevents fluid communication between the inactive tube and the manifold box comprising a manifold plate according to the invention.
  • Such an inactive tube can then form a thermal barrier between the groups of active tubes.
  • blind slot and / or the number of blind slots depends on the choice of the distribution of the slots of the collector plate between the two groups of open slots. More particularly, such a choice depends in particular on the number and the desired distribution of active tubes placed in fluid communication with the respective compartments of the manifolds. Thanks to the arrangements provided for by the present invention, at least one tube of said bundle of tubes is made inactive in a reliable and lasting manner.

  • the discharge of material is for example carried out during a stamping operation of the collector plate aimed simultaneously at forming the open slots and the blind slots.
  • the cover can thus come from the material forced out of the blind slot during such a stamping operation.

  • Such a cell makes it possible to maintain the end of the tube in the pre-assembled position in the collector plate, before passing through the brazing furnace.
  • a depth of the blind slot is at least equal to two thirds of the individual depth of the open slots. These depths are measured in a direction perpendicular to the large faces delimiting the collector plate.
