Definitions
- Heat exchanger collector box especially for a motor vehicle, said box lid and heat exchanger comprising such a box
- the invention relates to a heat exchanger collector box, in particular for a motor vehicle. It also relates to a lid of said box and a heat exchanger comprising such a box. It may in particular be radiators in which circulates a heat transfer liquid for cooling the vehicle engine and intended to be located on the front of said vehicle.
- Collector boxes comprising a metal collector plate and a plastic cover crimped onto said plate are known. To seal between the lid and the box, an elastomeric seal is used.
- the manifolds are provided with a groove inside which the seal is arranged so that it can be compressed between the lid and the header plate during crimping.
- Boxes have also been proposed in which the so-called flat plates do not have a groove.
- the seal then bears against the face of the header plate at which the passage openings of the fluid flow tubes open, at least at the longitudinal ends of the boxes.
- Such boxes are mainly of interest to reduce the size and weight, especially the weight in use, of the exchanger. Indeed, in the absence of groove for the seal, the dimensions of the collector plate are reduced. It is the same for the internal volume of the box and the amount of fluid to be circulated in the exchanger can thus be limited.
- said extended seals comprising a bead, to ensure the sealing function of the seal, and a portion of fixation bearing on the ends of the tubes, called in the following outer tubes, located on either side of the beam.
- Said fixing portion thus makes it possible to install the extended joint on the header plate which ensures the correct positioning of the bead during crimping.
- such seals have tabs for their extension on said outer tubes.
- a first solution would be to increase the size of the boxes but that would go against the goal pursued with planar plate collectors.
- the invention aims to improve the situation and proposes for this purpose a heat exchanger collector box, particularly for a motor vehicle, comprising a header plate, a cover and a seal, providing a seal between said collector plate and said cover, said seal comprising a fixing portion configured to bear on at least one fluid circulation tube of the exchanger, said fixing portion having a gripping projection of said seal, said cover having at least one housing accommodating said projection of gripping.
- Such an arrangement allows the use of extended type joints while avoiding a compression of the gripping projection of said joints between the tube and the lid of the manifold. This reduces the risk of deformation of the outer tubes of the exchanger while being able to use planar plate collector exchangers.
- the housing or said housings are located at one or more ends of said cover,
- said collector plate is crimped to said cover on either side of said housing
- said collector plate comprises two crimping teeth bearing on a shoulder of the cover situated on either side of said housing, said crimping teeth resting on the shoulder of the lid situated on either side of said housing are on a first side of the collector plate, said collector plate comprises crimping teeth on sides adjacent to said first side and crimping teeth on either side of the housing have a width greater than that of the teeth on said adjacent sides,
- said lid comprises a vault extended by a box foot, said box foot serving to compress the seal, a bottom wall of said housing being situated at the right of said box foot;
- said bottom wall is in the continuity of said box foot
- said housing is defined by a localized deformation of a profile of the vault of said cover.
- the invention also relates to a collector box cover as described above.
- the invention also relates to a heat exchanger, especially for a motor vehicle, comprising such a manifold.
- FIG 1 is a schematic overview of a heat exchanger to which manifolds according to the present invention are intended.
- FIG 2 partially illustrates, in perspective, one of the manifolds of the exchanger of Figure 1, said box being shown from the inside, the cover and the collector plate being cut transversely.
- Figure 3 partially illustrates, in perspective, the seal of Figure 2, taken alone.
- FIG. 4 illustrates, in longitudinal sectional view, the collector box portion illustrated in FIG.
- Figure 5 partially illustrates, in perspective, said box, seen from the outside, mounted on the exchanger.
- Figure 6 partially illustrates, in perspective, the lid of said box, seen from the inside.
- FIG 7 partially illustrates, in perspective, said lid, seen from the outside.
- the invention will find its applications in a heat exchanger comprising tubes 2 here forming a beam wherein said tubes 2 are parallel to each other.
- Each tube 2 has two longitudinal ends connected, in a fixed and sealed manner, to manifolds 3 of the exchanger for the circulation of a fluid, in particular a cooling liquid or the like.
- Said exchanger may include cheeks 48 for laterally protecting the beam.
- tubes 2 E said outer tubes, located on either side of said beam.
- interleaves 17 increasing the heat exchange surface between the fluid flowing in said tubes 2, 2 E and a fluid, including air, passing through the exchanger.
- spacers 17 may also be used between the outer tubes 2 E and the cheeks 48.
- Flanges or tubing inlet 5 and outlet 6 of the fluid are here respectively reported to the manifolds 3.
- the invention relates more particularly to manifolds 3 of said exchanger.
- the one or more manifolds 3 comprise a header plate 5, a cover 6 and a seal 7, sealing between said header plate 5 and said cover 6.
- Said box 3 is here of elongated shape, in particular of substantially parallelepiped shape.
- the collector plate 5 is, for example metal, including aluminum or aluminum alloys.
- the lid 6 is, for example, plastic. It is crimped on the collector plate 5.
- Said collector plate 5 comprises, for example, a medallion 8 and a raised edge 9 coming from the periphery of said medallion 8. Said raised edge 9 is provided with crimping teeth 1 0.
- Said collector plate 5 here has orifices 1 2, 12 'Through which the tubes, not shown in Figure 2, open at their ends in an interior defined by said boxes 3. Said holes 12, 12' for passage of the tubes are, for example, in a central portion of the medallion 8 , surrounded by a peripheral portion accommodating said seal 7.
- Said medallion 8 is here substantially rectangular.
- Said collector plate 5 is advantageously of the flat plate type.
- said header plate 5 has no or only partial groove housing of the gasket 7.
- Said collector plate 5 is thus configured to that the seal 7 bears on a face 14 of the medallion 8, face 14 at which the orifices 12, 12 'for the passage of the fluid circulation tubes open internally into the manifold 3, at least at the level of the or longitudinal ends of said manifold 3.
- said manifold plate 5 may further comprise flanges 16, 16 'for passage of the tubes, protruding internally from said flat face 14, without this calling into question the type of the collector plate used.
- said header plate 5 is configured to receive the seal 7 to the right of the peripheral portion of the medallion 8 at said flat face 14, this at least at the longitudinal ends of the boxes.
- the seal 7 is received at said plane face 14 over the entire contour of said seal 7 or at least at the portion of its contour lying between the orifice 12 'and / or the collar 16' of passage of the outer tubes and the portion of the raised edge 9, located vis-à-vis.
- Said cover 6 comprises, for example, a vault 18 extended by a box foot 20 intended to come into correspondence with the peripheral portion of said peripheral portion of the medallion 8 of the collecting plate 5.
- said gasket 7 comprises a bead 21.
- Said bead 21 forms a closed contour, corresponding to the profile of the peripheral portion of the medallion 8 of the header plate 5, namely here a substantially rectangular profile.
- Said cord 21 has, for example, a circular section.
- Said seal 7 also comprises at least one attachment portion 22, configured to bear on a fluid circulation tube of the exchanger.
- Said fixing portion 22 is here at one and / or the other end of the seal 7. It cooperates in this way with the associated outer tube 2 E.
- Said fixing portion 22 is, for example, in the form of a bar of material issuing from the cord 21, along one or the short sides of said cord 21.
- Said fastening portion 22 has a gripping projection 24 of said seal 7. It may be, for example, a tab from said bar of material.
- said bead 21 seals between said collecting plate 5 and said cover 6 by being compressed between the box foot 20 and the peripheral portion of the medallion 8. of the collector plate 5, during the crimping of the cover 6 on said collector plate 5.
- Said fixing portion 22 serves to hold the seal 8 in position, making its implementation in extension between the outer tubes 2 E.
- said lid 6 has at least one housing 30 accommodating said gripping projection 24.
- Said housing 30 is in particular configured to create a space between the outer tubes 2 E and the lid 6, at the level of said gripping projection 24, space allowing said gripping projection 24 to be kept at a distance from said cover 6 or, at the very least, to be only in flush contact, that is to say in contact with said cover 6 without being deformed by the latter.
- the housing 30 allows the remainder of the lid 6, in particular the portion 32 of the arch 18, not to be in contact with said gripping portion 24. This prevents the compression of the said gripping projection 24 between the outer tubes 2 E and the vault 18 of said cover 6.
- said collector plate 5 can be crimped to said cover 6 on either side of said housing 30.
- the collector plate 5 thus comprises, for example, two crimping teeth 1 0 'resting on a shoulder 36 of the cover 6, located on either side of said housing 30. Said shoulder 36 can make the rest of the turn of said cover 6 to cooperate with the other crimping teeth 10.
- the crimping teeth 10 'bearing on the shoulder 36 of the cover 6 located on either side of said housing 30 are here at a first side 38 of the header plate 5, namely at the level of the one or its longitudinal ends, and said manifold plate 5 comprises said other crimping teeth 10 on adjacent sides 40, 42 to said first side 38.
- the crimping teeth 10 'located on either side of the housing 30 may present a width greater than that of the teeth 1 0 located on said adjacent sides 40, 42.
- Said collector plate 5 here comprises a fastening tab 46 of one of said cheeks 48 of the exchanger.
- Said tongue 46 comes from the raised edge 9. It is located between said crimping teeth 10 'located on either side of said housing 30. Said tongue 46 and said housing 30 are in this way at the same level, from and other of said raised edge 9.
- a bottom wall 44 of said housing is situated, for example, at the right of said box foot 20.
- Said bottom wall 44 is, for example, in the continuity of said box foot 20.
