Definitions

  • the invention relates to a collector plate for heat exchanger and a heat exchanger provided with such a plate.
  • a header plate for a heat exchanger comprising a core provided with openings for the passage of tubes of the heat exchanger and a groove, said receiving a cover of collector box, adapted to receive a seal and a portion of the lid and having a base and two wings, respectively called internal and external and connected to the base; this corresponds to the preamble of claim 1.
  • a plate is known from JP 2005326124 A .
  • the bundle of tubes and inserts is first assembled. Then, the two collector plates are assembled at the ends of the tubes of the bundle. This set is then placed in a brazing furnace where these different components will be brazed together. Finally, it is secured, by crimping and with the interposition of a seal positioned in the groove, a cover on each header plate to define a manifold for collecting the fluid flowing in the tubes of the heat exchanger .
  • the receiving groove is present all around the collecting plate.
  • the invention aims to improve the situation.
  • a collector plate as defined above, in which the inner wing is connected to the core and is subdivided into at least two disjoint sections, said two disjoint sections being separated by at least one recess, and recess between two disjoint portions of the inner wing being at least at a location of the header plate for receiving a bent portion of the joint.
  • Such a collector plate does not have an internal wing at least at a bend (or corner) of the outer wing.
  • the inner wing is partially provided along the edges of the header plate.
  • a header plate according to the invention has a larger space at least at the corners of the latter so that a seal will be placed more easily by an operator.
  • the invention also relates to a manifold for a heat exchanger, comprising at least one cover fixed on a collector plate as described above.
  • the invention also relates to a heat exchanger comprising a collector plate as described above. More particularly, the heat exchanger may comprise a heat exchange bundle for the exchange of heat between at least two fluids.
  • the heat exchanger comprises at least one cover having an end, called a cover foot, introduced into the receiving groove and having a protuberance placed opposite the recess of the internal wing, the protuberance filling the recess of the inner wing so as to make a junction between the two disjoint sections located on either side of the recess.
  • the invention relates to a header plate 10 for a heat exchanger.
  • the header plate 10 comprises a core 12 provided with openings for the passage of tubes 100 of the heat exchanger and a groove 14, said receiving a cover 102 of collector box, adapted to receive a seal 104 and a part of the cover called the cover foot.
  • the groove 14 allows the placement of a seal 104 or the like, and its relatively firm hold, once in place, until the attachment with a lid, and more particularly a foot of the lid.
  • the collector plate 10 has a periphery, here, of substantially rectangular shape with two said large sides 22 and two so-called small sides 24.
  • the body of the collector plate 10 is made of metal, for example aluminum or an aluminum alloy.
  • the collector plate 10 is derived from a strip of metal sheet.
  • the header plate 10 as having at least two sides located vis-à-vis one of the other, namely respectively the two long sides 22 and the two small sides 24.
  • the two small sides 24 may subsequently be designated by the term "ends of the collector plate”.
  • the core 12 has holes (or orifices) for receiving the tube ends 100 of the heat exchanger and are adapted to the shape of their ends.
  • the holes are each surrounded by a collar having two pairs of opposite sides.
  • the collars are directed towards the inside of the header plate, or more precisely towards the inside of the manifold. In other words, the collars will extend, once the cover 102 mounted on the collector plate 10, inside the volume defined by the collector plate 10 and the cover 102.
  • the collars may extend not towards the inside of the collector box but towards the body of the tubes 100.
  • the collars will be oriented towards an exchange beam of heat comprising tubes and spacers.
  • These collars can be formed by punching and lifting or puncturing the plate.
  • the receiving groove 14 has, here, a U shape on at least a portion of the periphery of the header plate 10 and comprises a base 18 and two wings 16 and 20 respectively internal 16 and external 20 and connected to the base 18.
  • the shape of the groove can be seen as a three-sided structure with a base 18 extending in a first plane and two wings 16 and 20 substantially perpendicular to said first plane.
  • the outer wing 20 (which may still be called the peripheral wing 20) is, for its part, the receiving groove 14 farthest from the holes for the passage of the tubes 100.
  • the outer wing 20 is continuous on the around the collecting plate and has a shape with substantially straight portions opposed in pairs and connected by elbows.
  • the substantially straight portions correspond in the embodiments illustrated here, next to the collector plates, that is to say the long sides 22 and the small sides 24.
  • the elbows coincide with the corners 26 of the collector plate 10.
  • the collector plate has an outer flange 20 having four straight portions 34-1 and / or 34-2 opposed in pairs, each straight portion 34-1 and / or 34-2 being connected to a straight portion 34-1. and / or 34-2 adjacent by a bend 26.
  • the header plate 10 also has an inner flange 16 at least partially facing said four straight portions 34-1 and / or 34-2 so as to define four recesses 30 opposite each elbow 26.
  • a particular embodiment proposes that the inner wing 16 is connected to the base 18 by a connecting zone comprising a rounded and inclined stop so as not to damage a seal placed in the groove 14.
  • the outer flange 20 has crimping teeth or crenellations 28. These teeth 28 are distributed along the outer flange 20.
  • the collector plate comprises crimping teeth 28 located on at least a portion of the end edges of the header plate, adapted to ensure the fixing by crimping with a portion of the cover.
  • the crimping teeth 28 may be obtained by cutting. Other ways of fixing the cover on the header plate 10 may be considered.
  • the inner wing 16 is connected to the core 12.
  • the core 12 and the inner wing are in continuity of material.
  • it is the part of the receiving groove 14 closest to the holes for the passage of the tubes 100.
  • the inner wing 16 is subdivided into at least two disjoint sections, said two disjoint sections being separated by at least one recess 30 and the recess 30 between two disjointed portions of the inner wing 16 being at least level of a location of the header plate 10 for receiving a bent portion of a joint.
  • the recess 30 between two disjoint portions of the inner flange 16 is at least placed opposite a bend 26 of the outer flange 20.
  • the inner wing 16 can be seen as being formed by an alternation of slots spaced by recesses.
  • the inner wing 20 is interrupted in places and, according to the invention at least at a corner of the header plate 10.
  • the disjointed sections of the inner flange 16 are located opposite at least two of said opposite straight portions of the outer flange 20.
  • the core 12 has at least two bearings, respectively said upper 12-1 and lower 12-2 located in two separate planes and here connected by a so-called intermediate portion 12-3.
  • the upper bearing 12-1 may also be called protruding part or part "medallion".
  • the medallion part of the collector plate is obtained, for example, by stamping.
  • the lower bearing 12-2 may, for its part, be called “flat area”.
  • the expression “flat area” means that one of the orifices 108 (or openings 108 for the passage of the tubes) is at the lower level of the collector plate (as opposed to the protruding part), that is to say say at the base 18 of the peripheral groove 14 of the header plate.
  • the flat area is a zone without relief, so no groove or protuberance of any kind, except the collars located around the openings / openings passage tubes.
  • the intermediate portion 12-3 may, for its part, be designated by the term "part inclined plane".
  • the inclined portion may also be obtained by stamping, preferably during the formation of the protruding portion (or upper bearing) forming a medallion.
  • the upper bearing 12-1 (or the medallion protruding portion) is directly, and without transition, followed by the intermediate portion 12-3 (or inclined portion) to the lower bearing 12-2 (or the end of the collector plate formed by the flat area).
  • the base 18 of the receiving groove and the lower bearing 12-2 both extend in the first plane.
  • the base 18 of the receiving groove and the lower bearing 12-2 extend in the same plane (here, it is the first plane).
  • the upper bearing 12-1 extends, meanwhile, in a plane parallel to the foreground.
  • the recess 30 is disposed at the end of the collector plate 10. In other words, the recess 30 is located near the small side 24 of the collector plate 10.
  • the latter is placed opposite two elbows 26 and a small side 24 of the outer wing, said small side 24 being adjoining audits two elbows 26.
  • the interrupted portion of the inner wing 16 is U-shaped.
  • one of said bearings (here, the lower bearing 12-2) is located at the recess 30 between two disjoint portions of the inner wing 16.
  • the recess of the outer flange 16 is contiguous with the lower bearing 12-2.
  • the lower level 12-2 and the base 18 are not distinct and form a single level located on a single plane (here, it is the foreground).
  • the lower bearing 12-2 comprises, in this embodiment, a passage hole for a tube surrounded by a collar.
  • the collar and / or a tube will retain the seal 104 during assembly of the heat exchanger.
  • one of said orifices suitable for fixing tubes and located at the end of the collector plate is located in the plane zone.

  • a seal 104 is positioned in the portion forming the groove 14 due to the medallion portion and against the raised edges of the header plate 10. Due to the presence at at least one of the ends of the header plate 10 of a flat area (or bottom bearing 12-2), there is a much larger place (if there was a groove 14 to the end of the plate 10) so that the seal 104 is easily set up by an operator.
