  • the header plate generally has a peripheral groove inside which is placed a seal. The edges of the lid are inserted into the peripheral groove to compress the seal.
  • An object of the present invention is therefore to at least partially overcome the disadvantages of the prior art and to provide a collector and a heat exchanger whose connection between the cover and the collector plate is improved.
  • the present invention therefore relates to a collector for a heat exchanger comprising:
  • collector plate including orifices for receiving tubes, said manifold plate comprising a peripheral groove
  • These retaining elements form stops and prevent the cover and more particularly the ends of its side walls from sinking beyond a certain limit in the peripheral groove. These retainers allow the seal 44 to be sufficiently compressed to seal while preventing it from being excessively compressed which could damage it.
  • the collector plate has a generally rectangular shape with two large sides and two small sides, the retaining elements bearing simultaneously on the two long sides and / or the two small sides simultaneously of said collector plate 4.
  • the retaining elements are formed on the outer face of the side walls and bear against the outer rim of the peripheral groove.
  • the outer rim of the peripheral groove comprises crimping tabs and the retaining elements abut between two crimping tabs.
  • the retaining elements are made on the inner face of the side walls and bear against the inner rim of the peripheral groove.
  • the lid on the same side of the plate the lid comprises a single continuous retention element along the length of said side of the header plate.

  • first element or second element as well as first parameter and second parameter or else first criterion and second criterion, etc.
  • first criterion and second criterion etc.
  • it is a simple indexing to differentiate and name elements or parameters or criteria close but not identical.
  • This indexing does not imply a priority of one element, parameter or criterion with respect to another, and it is easy to interchange such denominations without departing from the scope of the present description.
  • This indexing does not imply either an order in time for example to appreciate such or such criteria.
  • FIG. 1 shows a heat exchanger 1, generally of parallelepipedal shape, comprising a beam formed of a multitude of tubes 2 to inside which can circulate a first heat transfer fluid.
  • the tubes 2 are of oval or oblong section, defined by a major axis and a minor axis and are arranged parallel to each other so as to form a row of tubes 2.
  • the tubes 2 and the spacers 6 are generally made of metal.
  • the tubes 2 and the spacers 6 forming the bundle may be fixed together by brazing.
  • the spacers 6 are then called spacers and are for example corrugated or crenellated strips, placed between the tubes 2 and fixed to said tubes 2 by soldering. This is called a brazed beam.
  • the tubes 2 and the spacers 6 forming the bundle can be fixed together by mechanical fastening.
  • the spacers 6 are then called fins and are for example metal plates having orifices in which the tubes 2 pass.
  • the tubes 2 are fixed in these orifices by expansion of their diameter. This is called a mechanical beam.
  • the heat exchanger 1 also comprises two manifolds 3 or water boxes, a manifold 3 being disposed at each end of the tubes 2. These manifolds 3 each comprise a header plate 4 and a cover 8 coming to cover the header plate 4 and close the manifold 3 so as to form a chamber 30 (visible in Figure 2) in which can circulate the first heat transfer fluid. These collectors 3 allow the collection and / or distribution of the first heat transfer fluid so that it circulates in the tubes 2.
  • the collector plate 4 is sealingly connected between the collector 3 and the bundle of tubes 2.
  • the collector plate 4 may be of generally rectangular shape with two long sides and two small sides.
  • the collector plate 4 also comprises a multitude of orifices having a shape corresponding to the shape of the section of the tubes 2 and adapted to receive the ends of the tubes 2. The orifices are therefore arranged in a row parallel to the large side of the collector plate 4.
  • the tubes 2 can be fixed to the header plate 4 in a sealed manner by soldering, which is called a brazed heat exchanger.
  • the tubes 2, the spacers 6 and the collector plates 4 may be made of a metal material including aluminum or aluminum alloy in order to have good thermal conductivity and allow brazing.
  • the cover 8 can be made of plastic material.
