Definitions

  • the invention relates to the field of heat exchangers, in particular for motor vehicles.
  • the invention relates to a heat exchanger according to the preamble of claim 1.
  • a heat exchanger is known for example from DE 4243495 .
  • the heat exchanger is brazed, that is to say the various elements are permanently fixed to each other by a soldering operation (provision of a solder layer and passage in a dedicated brazing furnace).
  • Motor vehicle heat exchangers such as radiators and charge exchangers, use manifolds, forming an intake or exhaust chamber, in one or more rooms.
  • these collector boxes have at least two parts, one of these two parts forming the header plate and the other forming the cover intended to be fixed on the header plate to at least partially close the manifold.
  • the manifolds are generally of two types, namely of the "all-metal” type or of the type with a plastic cover.
  • the type of "all-metal" header box has a certain number of advantages over the type of plastic cover header box which requires the attachment of a sealing means, conventionally an elastic seal, to ensure perfectly sealed connection between the cover and the collector plate.
  • the header plate has a groove or groove for placing and positioning the seal. Then, the lid is positioned on the seal and then, conventionally, the collector plate is crimped, for example by means of teeth located on the periphery of the header plate.
  • header manifold plates do not have a groove or groove to facilitate the positioning and maintenance in place of the seal.
  • the main problem lies in the positioning of the sealing gasket on the header plate, before the introduction of the cover, because this positioning operation of the seal is the main cause of difficulties in production.
  • This bad positioning of the seal can have several causes.
  • the seal may have a manufacturing defect that causes it to twist, this intrinsic defect of the seal is not easily identifiable because of the dimensions of the seal, or its color. Furthermore, if the seal is too long, there will be wave formation according to its profile when fixing the cover. This results in unsatisfactory sealing and leakage of fluid in the longer term.
  • the positioning of the seal is usually a manual operation performed by an operator because the use of a machine is difficult, the main problem of the automatic positioning of the seal lies in the ability of the machine to take or enter the seal between a plurality of seals stored in a tank or the like. Furthermore, the seals are conventionally made of rubber and may therefore be easily damaged.
  • the sealing gasket comprises protuberances located at the four corners which allow to stretch the seal, these protuberances then being placed in dedicated slots on the collector plate.
  • a major disadvantage of this solution lies in the need to make slots at different angles of the header plate, which constitutes an additional manufacturing cost and weakens the resistance of the header plate, in particular its resistance to cyclic pressure.
  • the protuberances of the seal protruding from the manifold (also called “collector"), they increase the size of the manifold (packaging).
  • the document FR 2867553 discloses a solution in which is made on the lid pins, arranged at the corners, for holding the seal in shape, and possibly its tensioning. This solution makes it difficult to ensure a good positioning of the seal along the lid because it can easily fall during handling of the lid until it is placed on the collector plate.
  • the present invention aims to overcome the drawbacks of collector boxes of the prior art by proposing a solution for simply and securely attaching a seal on a header plate and for the subsequent perfect attachment of the cover on the header plate.
  • An advantage of the invention is to allow satisfactory positioning of the seal including when the header plate is not provided with a groove.
  • the invention consists of a heat exchanger according to claim 1.
  • the advantage of the invention lies essentially in the particularly safe positioning of the sealing means on the header plate, the sealing means being placed in abutment and tension on at least the ends, opening into the box, tubes are located on either side of the beam, avoiding any loss of it and any possibility of a bad positioning (twisting, reversing, twisting or other) of the sealing means on the header plate and with respect to the cover ( or foot cover), without requiring any additional device or complex operation.
  • end of tube means only the extremal part of the protruding tubes, from the collecting plate, in the header (or the space of the collecting box), or also the collars which generally have a protuberance with respect to the collector plate.
  • the end of the tube may concern the tube (s) and / or the collar (s).
  • steps a), b), c) are performed automatically by a machine, or manually by an operator.
  • the figure 1 has the sealing means 1 which consists here of an elastic seal 1 having a periphery 2 of rectangular shape, with two long sides 3, 3 'and two small sides 4, 4'. Furthermore, this seal 1 comprises two transverse portions 5, that is to say that each of these portions 5 connects two opposite edges 3, 3 'or 4, 4', here perpendicularly and between the two long sides 3, 3 'of the periphery 2 of the seal 1. These perpendicular portions 5 also extend substantially perpendicularly to the plane of extension of the seal 5, that is to say vertically relative to the plane defined by the periphery of the seal 1. Furthermore, as this is visible on Figures 2 and 3 these vertical portions 5 are slightly offset, that is to say they rise starting above the lower level 6 of the seal 1.
  • the section of the seal 1, except at the aforesaid portions 5, has a circular section while each of the portions 5 has a substantially rectangular section.
  • the circular section of the seal 1 is particularly adapted to the use made of said seal 1 (but could of course have another shape) but the rectangular section of the aforesaid portions 5 is instead chosen as an example and may be different, for example it may consist of a circular section, ovoid or other forms suitable for gripping by an automatic arm or an operator's hand.
  • each of the gripping portions 5 is free, provided that these portions 5 are sufficiently solid for their handling and that they can easily be placed between the ends of the tube 7.
  • the Figures 4 to 9 illustrate the successive stages of implementation of the seal 1 on the header plate 8.
  • the seal 1 chosen to illustrate the method of implementation on the header plate 8 is identical to that 1 presented on the Figures 1 and 2 .
  • this installation is illustrated by means of a machine (not shown in the appended figures), that is to say an implementation performed automatically with the aid of two pairs of vices 9, 9 ' set in motion by a machine, no shown in the accompanying figures.
  • Note simply that the establishment of the sealing means 1 will be substantially the same way if the steps are performed by a (simple) operator.
  • the figure 7 illustrates in section the seal 1 in tension which has been placed on a collector plate 8.
  • Said collector plate has a series of orifices 20, arranged in a direction of extension of the plate, said orifices 20 allowing the passage of a plurality of tubes 7 or the like in which circulates at least one fluid.
  • Said holes 20 have, for example, an oblong section with two long sides parallel to each other, connected on each side by a semicircle shape, in correspondence of the section of the tubes used.
  • Said orifices are arranged parallel to one another below, their major axis being arranged orthogonally to the direction of longitudinal extension of the plate. In the illustrated example, it is a collector plate without groove or groove.
  • the machine by means of its vices 9, 9 ', moved the seal 1 to position it above the collecting plate 8 and these vices 9, 9' are lowered to remove the seal 1.
  • the gripping means 10 are located respectively at both ends 11 of the seal 1 ', namely on the two small sides 4, 4' vis-à-vis.
  • gripping means 5, 10 is of little importance so that there may possibly be only one gripping means 5 or 10 or on the contrary more two gripping means 5, 10 located at suitable locations on the seal 1, 1 '.
  • These gripping means 5, 10 can be made in a different material from that used to form the seal 1, 1 ', more precisely the periphery or the periphery 2 of the seal 1, 1', for example another type of plastic more resistant and less elastic than for the periphery 2 of the seal 1, 1 ', for example by combining a polyamide for the gripping means 5, 10 and a rubber-latex (with more important properties) for the circumference or the circumference 2 of the seal 1, 1'.
  • the zone formed between the gripping means 5 or 10 it is important for the zone formed between the gripping means 5 or 10 to be an essentially elastic area of the seal 1, 1 'so that the seal 1, 1 can be easily stretched. by acting on the gripping means 5 or 10.
  • the gripping means 10 of the second embodiment consist of an axial protuberance consisting of two parts, a first upper contact portion 12 with one or more tube ends 7 and a second recessed portion 13 providing the connection between the periphery 2 of the seal 1 'and the contact portion 12. From the periphery 2 of the seal 1' extends the second portion 13, substantially at the same level or height as the periphery 2 while the first portion 12 extends above the second portion 13 and has a protruding axial portion.
  • the first portion 12 has an axial offset vis-à-vis the second portion 13 so that the second portion 13 is said recessed, relative to the first portion 12 of contact.
  • the axially protruding portion of the first portion 12 is the portion of the seal 1 'in contact with the tube ends 7.
  • This particular structure of the gripping means 1 'in the second embodiment has advantages as to the behavior of the seal 1' under tension.
  • the first part 12 of the means By sealing against the end of the tube 7, a resultant force will tend to press the second portion 13 back against the collar 16, thus avoiding any risk of twisting or twisting of the seal 1 '.
  • the seal 1 ', via its gripping means 12 will be perfectly pressed against the end (s) of tube 7 and against the flange 16 possibly present and protruding from the collector plate 8'.
