Definitions

  • the invention relates to heat exchangers, especially for a motor vehicle.
  • a heat exchanger of the type comprising a finned tube bundle and a collector which has a central core, in which is arranged at least one row of holes flanked by collars for receiving the tubes of the bundle, and a peripheral groove connected to the central core by a folded edge.
  • Heat exchangers of this type are used in motor vehicles, in particular to constitute an engine cooling radiator or a radiator for the heating of the passenger compartment.
  • Such heat exchangers can be made in the form of two main types which are respectively called mechanical assembly type exchangers and brazed type exchangers.
  • the ends of the tubes are received in the collets of the header plate with the insertion of corresponding sleeves forming part of a seal. These seal sleeves are squeezed by flaring of the tubes, providing a seal.
  • the ends of the tubes are received directly in the collars of the collector plate and are brazed to the collector plate.
  • peripheral groove which surrounds the central core of the collector is connected to this central core by a folded edge which is generally made in the form of an edge substantially right that connects perpendicularly to the central core.
  • the peripheral groove is intended to receive the periphery, also called foot, a collector box.
  • the latter defines with the collector a volume that is in communication with the tubes of the beam.
  • the manifold foot squeezes a peripheral region of the seal that is received in the peripheral groove. This compression is usually obtained by crimping means, which ensures a seal.
  • the peripheral groove also receives the periphery of the header to provide a solder connection.
  • the folded edge and the collars generally extend on the same side of the central core and, until now, the region of the collars, which is closest to the folded edge, is at a distance that usually can not fall below a value of the order of 1mm.
  • this folded edge has a contour of generally rectangular shape and has in particular two longitudinal sections which extend parallel to the long sides of the collector and also parallel to the row (s) of the tubes.
  • a heat exchanger is known from FR-1.577.223.
  • the object of the invention is in particular to overcome this drawback.
  • each collar is substantially in contact with said folded edge so as to define between them a set of a minimum value.
  • the Applicant has found that, by means of a particular manufacturing method, which may for example use stamping punches, it is possible to ensure that each collar comes into substantially contact with the folded edge, which makes it possible to define a set of a minimum or even zero value.
  • the value of this game is advantageously between 0 and 1mm.
  • peripheral groove surrounds more closely the central core of the collector, which allows to significantly reduce the size.
  • the collars are advantageously made by means of stamping punches.
  • the ends of the tubes can be either received in the collets with the interposition of a seal, or be brazed in the collars.
  • the invention applies to different shapes of collars and ends of the tubes.
  • the necks and ends of the tubes may in particular have a generally circular shape, or a generally oblong shape, in particular oval or elliptical.
  • a fin is in contact with the collector in the region of the peripheral groove. This makes it possible to perform a protection function with respect to corrosion.
  • FIGS 1 and 2 show a collector 10 own part of a heat exchanger, especially for a motor vehicle.
  • This heat exchanger may constitute, for example, an engine cooling radiator or a heating radiator of the passenger compartment.
  • the collector 10 is made by stamping and stamping a metal plate which is advantageously based on aluminum.
  • This collector comprises a flat central core 12, of generally rectangular shape, in which is arranged a series of holes 14 of oblong shape, here of substantially elliptical shape, which are arranged in a row R of axis XX.
  • the largest dimension collars (which corresponds to the major axis AA of the ellipse) extends perpendicularly to the direction XX above ( Figure 2).
  • Each of the holes 14 is surrounded by a collar 16 which has the general shape of a cylinder of elliptical section.
  • the core 12 is surrounded by a peripheral groove 18 which is connected to the central core by a folded edge 20.
  • This folded edge connects perpendicular to the central core 12 and then connects, by a rounded, to a wall 22, which extends parallel to the core 12.
  • This bottom wall 22 is connected perpendicularly to an outer edge 24 which constitutes, at its free end, a crenellated edge defining a series of teeth or crimping tabs 26.
  • the folded edge 20 is connected to the collar 16 by a U-shaped folding 28 which is made such that an end region of the collar 16 is substantially in contact.
  • the folded edge 20 There is between them a game of a value d which is minimal.
  • this value d can reach a very low value which is typically between 0 and 1 mm.
  • the folded edge 20 comprises two main sections 20a and 20b which are parallel to each other and which are also parallel to the direction XX of the row. These two edges thus come into contact respectively with end regions 16a and 16b of each of the collars 16.
  • This collector is intended to constitute a heat exchanger partially shown in FIG.
  • each of the collars 16 is introduced the end 30 of a tube 32 which is part of a bundle of flat tubes and fins 34, which are traversed by the tubes.
  • the ends of the tubes are mechanically collected at the manifold via a seal 36 which is applied to the top of the manifold and which comprises a series of sleeves 38, each of which is compressed between a collar and an end of a tube.
  • This seal 36 continues with a peripheral edge 40 which is housed in the peripheral groove 18. This periphery is compressed by the foot 42 of a manifold 44.
  • the tabs 26 are intended to be folded to ensure the compression of the seal. sealing in the throat area 18.
  • peripheral groove 18 may have a different shape and generally receives the foot of the header and the latter is then secured by brazing.
  • one of the fins 34 of the beam comes into direct contact with the bottom wall 22 of the collector 10 in the region of the peripheral groove 18, which contributes to the corrosion resistance of the heat exchanger.
  • the invention can be applied to heat exchangers comprising one or more rows of tubes.
  • the ends of the tubes, as well as the corresponding collars may have different shapes, in particular a circular shape, an oblong shape, such as an oval or elliptical shape, etc.
  • the collar extend on the other side of the central core, that is to say on the side where the collecting box is located.
  • the invention finds particular application to heat exchangers for motor vehicles. It allows for heat exchangers whose collector has a small footprint, all things being equal, compared to exchangers of the prior art, which facilitates their implementation in motor vehicles.
