Definitions

  • the invention relates to the field of heat exchangers, in particular for motor vehicles.
  • a heat exchanger comprising a bundle of tubes, at least one collector in which the tubes of the bundle open, and a collector box covering the collector.
  • Such a heat exchanger may constitute, for example, a cooling radiator of the vehicle engine, a heating radiator of the passenger compartment, or an evaporator or a condenser of an air conditioning circuit.
  • the tube bundle is usually mounted between two manifolds via their respective manifolds, and is adapted to be traversed by a fluid.
  • this fluid is the liquid used for cooling the engine.
  • this fluid is a refrigerant.
  • the collector is usually made in the form of a plate which is provided with holes for receiving the ends of the tubes of the bundle. These holes are generally flanked by a collar to facilitate a sealed assembly between the collector and the tubes of the bundle. This assembly can be carried out either by brazing or by means of a seal.
  • the manifold that caps the manifold is arranged to cooperate tightly with him.
  • the manifold can be made in the form of a metal piece which is soldered to the manifold.
  • manifold and the manifold constitute very different specific parts which are designed to cooperate with each other.
  • collector / collecting box assembly is known, the collector and the collecting box being formed by two half-shells in the form of two symmetrical half-pipes.
  • the manifold is provided with an elongated hole for receiving an end of a tube.
  • the invention aims to simplify the realization of a manifold / manifold and improve the pressure loss of the fluid flowing in the inside of the collector / manifold and tubes.
  • the invention comprises the features according to claim 1.
  • the manufacture of the manifold and the manifold is simplified since these two components use the same half-shell at the base.
  • the collector and the collector box can thus be obtained by common tools.
  • the two half-shells are made of metal, for example aluminum, and their respective flat seals are assembled by brazing.
  • the respective flat seals are formed towards the outside of the half-shells.
  • the flat seals thus formed towards the outside are advantageously maintained by at least one claw.
  • the respective flat seals are formed towards the inside of the half-shells.
  • one of the flat seals thus formed inwardly advantageously forms a stop against the tubes of the bundle.
  • the flat seals may have respective impressions of conjugate shapes which are intended to fit each other by shape cooperation to ensure a positional holding of the two half-shells.
  • a heat exchanger collector box has one or more pipes for entering or leaving a heat transfer fluid.
  • the two half-shells are formed with half-pipes generally symmetrical with respect to the junction plane, so as to form a complete tubing (also called “spacer”), when the two half-shells are assembled between them.
  • the half-shells are each formed by forming a metal sheet.
  • forming is meant at least one conventional mechanical operation, such as for example stamping, folding, rolling, etc.
  • the half-pipes are also formed during the forming of the two half-shells.
  • At least one of the flat seals is extended outwardly by a tongue serving, for example, the positioning and / or fixing of the heat exchanger.
  • the heat exchanger also comprises corrugated spacers placed between the tubes, the assembly being formed by brazing.
  • FIGS 1 and 2 partially show a heat exchanger 10 according to the invention comprising a beam 12 formed of flat tubes 14, parallel to each other, and between which are arranged corrugated inserts 16.
  • the tubes 14 are received in a manifold 18, which is capped by a manifold 20 to form a volume that communicates with the tubes 14 of the beam.
  • the assembly can be traversed by a heat transfer fluid which exchanges heat with a flow of air sweeping the beam.
  • the tubes 14 of the bundle are advantageously received in an identical or similar collector (not shown), also capped by a manifold (not shown).
  • the manifold 18 and the manifold 20 are formed of two generally symmetrical half-shells, assembled on either side of a junction plane P.
  • these two half-shells are identical and they have respective flat seals 22 and 24 formed around the periphery of the shells and towards the outside.
  • the two half-shells 18 and 20 are advantageously formed by forming and in particular by stamping a metal sheet, preferably aluminum or aluminum-based alloy. These two half-shells are formed from the same basic elements and with the same tools. The only difference here lies in the fact that the half-shell forming the collector 18 must be further machined to form elongate holes 26 ( Figure 2 ) each adapted to receive an end of a tube 14. These holes are advantageously formed by cutting with the press. They are advantageously surrounded each by a collar improving the junction between the tube and the collector.
  • all the other components of the heat exchanger are made of metal, preferably in the same metal or metal alloy as the collector and the header.
  • the assembly is assembled by brazing, advantageously by passing through the oven, during a single operation.
  • the assembly of the manifold and the manifold is made in the same plane of junction with a flat landing against flat of the flat seals 22 and 24.
  • This design allows for shallow embossing, resulting in a gain of material.
  • some of the stamping may be common to both half-shells, which reduces the manufacturing time.
  • the flat berthing against flat makes it possible to obtain a good soldering.
  • This protruding element can be used, for example, for setting the heat exchanger in a housing. This is of interest especially when the heat exchanger is to be inserted and mounted in a housing of a heater and / or air conditioning of a motor vehicle.
  • FIG. 3 shows a collector / collector assembly similar to that of Figures 1 and 2 , but in an alternative embodiment.
  • the main difference here lies in the fact that one of the flat seals, namely the flat gasket 22, comprises two projecting tongues 28 and 30 which can be used, for example, for setting the heat exchanger in a housing (not represent).
  • a claw 32 for holding the two flat seals against each other.
  • the respective half-shells 18 and 20 are each formed with half-pipes 34 and 36 each having a substantially semicircular section. These two half-pipes are generally symmetrical with respect to the junction plane. Thus, when the two half-shells are joined together, the half-pipes 34 and 36 together form a complete pipe 38, also called "spacer".
  • This pipe serves for the entry or exit of a heat transfer fluid circulating in the heat exchanger.
  • the respective flat seals 22 and 24 of the two half-shells continue at the level of the half-pipes 34 and 36, thus improving the tight junction of these two half-pipes between them.
  • the two half-pipes 34 and 36 are advantageously formed by forming, in particular by stamping, at the same time as the two half-shells, which also facilitates the manufacture.
  • the interface with the tubings can be provided by a brazed element which surrounds the two half-shells.
  • This embodiment has the advantage of allowing an oblong connection, or even rectangle, on the box to water. This also allows a reduction in the height of the manifold, which results in a reduction of the material engaged and a reduction in size.
  • This design allows a connection of a tubulure either laterally on the manifold or at the end of the latter.
  • the embodiment of the Figure 5 differs from that of figure 2 in that the respective flat seals 22 and 24 are formed towards the inside of the half-shells, instead of the outside. Under these conditions, the forming of the half-shells can be obtained only by stamping and requires at least one additional operation to fold the flat seals inward.
  • one of the flat seals here the seal 22 forms a stop against the tubes 14 of the beam 12. This allows to automatically position the tubes in the axial direction relative to the manifold.
  • the flat seals 22 and 24 have respective indentations 40 and 42 of conjugate shapes which are intended to interlock with one another by form cooperation to maintain the two half-shells in position.
  • these impressions are obtained by a U-fold of each of the flat seals.
  • These impressions can be made either on the whole or on a portion of the periphery of the half-shells.
  • Such a heat exchanger may constitute, for example, a cooling radiator of the vehicle engine, a heating radiator of the passenger compartment, or an evaporator or a condenser of an air conditioning circuit.
