Definitions
- the present invention relates to a collector plate for a motor vehicle heat exchanger and a heat exchanger provided with such a collector plate.
- a heat exchanger conventionally comprises a bundle of tubes delimited by two end tubes.
- heat exchange fins may be provided between the tubes of the bundle to improve the heat exchange.
- An end heat exchange fin may be disposed on the outer face of each of the end tubes. The end heat exchange fins or fins thus delimit the bundle of tubes.
- a cheek is disposed directly on each end heat exchange fins mentioned.
- a heat exchanger further comprises two collector plates (or “collectors") which are traversed by the ends of the tubes of the bundle of tubes.
- the collector plates are each covered with a lid to form a water box.
- a first water box allows the distribution of the fluid passing through the tubes from a fluid inlet formed by a first cover.
- the second water box allows the collection of fluid having passed through the tubes, to lead to a heat exchanger fluid outlet, formed by the second cover.
- a heat exchanger may comprise two bundles of tubes, parallel and offset with respect to each other in a direction normal to the two bundles of tubes, successively traversed by the fluid to be cooled or heated.
- the inlet and the fluid outlet can be arranged at the same end of the bundles of tubes and formed by the same lid, the water box located at the other end for guiding the fluid from the leaving the tubes of the first bundle of crossed tubes to the inlet of the tubes of the second bundle of tubes to pass through.
- the tubes of the two bundles of tubes are traversed by fluid at different temperatures. It follows different dilations of the tubes between the first beam, traversed by a warmer fluid, and the second beam, traversed by a colder fluid. These different expansions can cause cracks or other damage in the manifold plates to which the tubes are attached, which affect the tightness necessary to effectively guide the fluid.
- An object of the invention is to provide a header plate to reduce or even completely avoid the appearance of these cracks and / or damage.
- the invention proposes a collecting plate for a motor vehicle heat exchanger, comprising a first tube receiving zone of a first tube bundle of a heat exchanger, and a second tube receiving zone. a second bundle of tubes of a heat exchanger, the header plate having a groove, the groove extending between the first and second receiving areas, the header plate having a thinning at the groove.
- the thinning of the plate at the groove allows to create a "deformation primer”, to soften the collector plate and facilitate the adaptation of the collector plate to the differential expansions of the tubes of the first and second beams.
- this thinning located between the two parts mentioned above, facilitates the relative pivoting of these two parts around this thinning.
- the header plate comprises one or more of the following characteristics, taken alone or in combination:
- thinning at the groove corresponds to a minimum thickness of the header plate at the groove, greater than 50% and / or less than 75% of a maximum thickness of the header plate at the groove;
- the groove is defined by a fold of the header plate; the fold has a "U"section;
- the thinning of the collector plate is at one or more angles of the "U" section of the fold
- the header plate has, on one side of the header plate opposite the face of the header plate with the groove, a groove or deformation reducing the thickness of the header plate;
- the groove is on one face of the header plate intended to be oriented towards a cover forming with the header plate at least one water box;
- the header plate is substantially rectangular in shape, preferably with rounded corners, and the groove extends in a longitudinal direction of the header plate;
- the first and / or second tube receiving zone comprises a plurality of slots, preferably parallel, each slot preferably being intended to be traversed by the end of a respective tube;
- each slot is at the top of a boss of the header plate, the boss preferably being of oblong shape, the length of the oblong shape being, more preferably, substantially perpendicular to the groove, the boss preferably projecting from the face the manifold plate with the groove;
- the collector plate forms a groove around the first and second receiving zones, the groove opening on either side of the groove.
- the invention relates to a heat exchange device for a motor vehicle, in particular to a motor vehicle engine cooling radiator, with two methodical passes comprising a first and a second bundle of tubes. , a first collector plate and a second collector plate, at least a first cover, preferably a single first cover, fixed on the first collector plate and forming an inlet and a water outlet, a second cover fixed on the second collector plate and forming a water guide between the first bundle of tubes and the second bundle of tubes, the first collector plate being as previously described, in all its combinations.
- the heat exchanger according to the invention comprises one or more of the following characteristics, taken alone or in combination:
- the heat exchange device also comprises a first gasket received in the groove of the first collector plate, arranged between the first collector plate and a wall of the first cover, to separate a distribution space placing fluid communication water inlet and the first bundle of tubes, a collection space, placing in fluid communication the water outlet and the second bundle of tubes, the seal being preferably section "U" ;
- the groove receiving a second single seal pinched between the first collector plate and a wall of the first cover, the seal being preferably section "U";
- the second seal has an "8" shape with a central branch, the central branch forming the first seal received in the groove of the first collector plate.
- Figures 1 and 2 show a heat exchanger for a motor vehicle, respectively in perspective and in front view;
- Figures 3 and 4 illustrates a header plate of the heat exchanger of Figure 1, respectively in perspective and in section along the line IV-IV;
- Figure 5 illustrates a detail of Figure 4;
- Figure 6 illustrates a variant of the detail of Figure 5.
- FIGS. 7 and 8 show in broken perspective and in exploded view, respectively, a detail of the assembly of the heat exchanger of FIG.
- FIGS 1 and 2 illustrate an example of a heat exchanger 10 (or heat exchanger).
- a heat exchanger 10 or heat exchanger
- it is a heat exchanger with two methodical passes, cooling of the gearbox and motor of a motor vehicle.
- Such an exchanger can for example cool water, which passes through it, with the aid of an air flow F created by the speed of movement of the motor vehicle.
- the heat exchanger 10 essentially comprises two bundles of tubes 12 (only one of which is visible in FIGS. 1 and 2) extending in two parallel planes, offset with respect to each other in a direction normal to the plans.
- the bundles of tubes are mounted between two collector plates 14, 16 receiving the ends of the tubes 12, and two side flanges 18, 20.
- the collector plates 14, 16 are of generally rectangular shape, in this case with rounded corners.
- the collector plates 14, 16 may be made of metal, in particular aluminum.
- a first cover 22 is fixed on the header plate 14, located at a first longitudinal end of the heat exchanger 10, the assembly thus formed being sometimes called a water box.
- the first cover 22 forms an inlet 24 and a water outlet 26 of the heat exchanger 10.
- the first cover 22 also forms, with the header plate 14, two spaces:
- a first so-called distribution space puts in communication fluid the water inlet 24 and a first bundle of tubes, in this case, the tube bundle not visible in the figure, intended to be placed downstream with respect to the direction of propagation of the cooling air flow F;
- a second so-called collecting space communicates the outlet of water 26 and the second bundle of tubes in fluid communication.
- a second cover 28 is attached to the header plate 16 located at the second end of the heat exchanger 10, opposite the first. This second cover 28 defines with the collector plate 16 a hollow space which puts in fluid communication the first and second bundles of tubes 12.
- this heat exchanger 10 can be summarized as follows: the hot water enters the heat exchange device 10 via the water inlet 24:
- the hot water passes through the distribution space formed by the first cover 22 and the header plate 14, towards the first bundle of tubes 12, situated downstream with respect to the second bundle of tubes 12, in the direction of flow air F, this first tube bundle 12 thus being in contact with air preheated by contact with the second bundle of tubes 12; at the end of the heat exchanger 10, opposite the water inlet 24, the water is turned around, guided by the cover 28, which directs the water to the second bundle of tubes 12;
- the water then passes through this second bundle of tubes 12, into the collection space formed by the first cover 22 and the header plate 14, which directs the cooled water towards the water outlet 26.
- the first bundle of tubes 12 is traversed by the generally warmer fluid than the fluid passing through the second tube bundle 12.
- the tubes of the first bundle of tubes therefore expand more substantially than the tubes of the second bundle of tubes.
- These two bundles of tubes 12 being fixed to the two collector plates 14, 16, in particular by brazing, the different expansions of the tubes induce forces on the collector plates, in a direction substantially parallel to the direction of extension of the tubes, and therefore substantially normal to the planes of the collecting plates 14, 16.
- the header plate 14 is here designed to limit the effects of these expansions, in particular to avoid the risk of occurrence of cracks or other more significant damage, which could affect the sealing of the plates collectors 14, 16, making the heat exchange device 10 inoperative or, at least, less effective.
- the header plate 14 comprises two zones 30, 32 for receiving the tubes of the first and second bundles 12 of tubes.
- these zones are symmetrical with respect to a longitudinal median plane of the plate 14.
- Each receiving zone 30, 32 is formed of substantially one half of the collector plate 14.
- Each receiving zone of the tubes 30, 32 comprises, for example, a single number of slots 34 for receiving the tubes of the bundles of tubes 12, the slots 34 being traversed by the end of the tubes so that they open respectively into the dispensing space or into the collection space defined with the first lid 22.
- the tubes can be brazed to the collector plate 14, in particular at these slots 34.
- the slots 34 are here made at the top of reliefs or bosses 36, with respect to the internal face 14a of the collector plate 14.
- bosses may be oblong, as shown in Figure 3, to make them more rigid and / or adapt to the shape of the tubes they receive the ends.
- the main direction of the oblong shape of the bosses 36 then corresponds substantially to the width of the header plate 14.
- the two receiving zones 30, 32 are separated by a groove 38 in the inner face 14a.
- the groove 38 is intended to receive a seal, sealing between the dispensing space and the collection space.
- the groove 38 extends here in a straight line corresponding to a longitudinal direction of the header plate 14. This form of the groove 38 is particularly adapted to receive a seal ensuring the seal between the header plate 14 and the first cover 22, seal whose geometry is preferably simple to ensure its effectiveness.
- the groove 38 is formed by a fold 40 of the header plate 14. This embodiment is particularly advantageous because the fold 40 can be made during the same drawing step as that forming the slots 34 and / or bosses 36.
- the fold 40 here has a section "U". This form of the fold 40 ensures greater flexibility. More specifically, and as can be seen in FIG. 5, in particular, the fold 40 comprises two flanges 42, 44 around a core 46, defining the bottom of the groove 38.
- the flanges 42, 44 form with the core an angle for example between 70 0 and 130 °.
- the angle between the cheeks and the core can in particular be defined as being the maximum angle between the tangents at the face 14a of the collecting plate 14, at the cheeks 42, 44, and a plane parallel to the extension plane of the collector plate 14.
- the collecting plate 14 has a thinning at the groove 38. More precisely, here, the thickness of the collecting plate 14 has a minimum e min , at least local, at the level of the groove 38. of the groove 38. This thinning can be done substantially at an angle or angles of the "U" section of the fold 40, that is to say at the corners 48 at the junction between the cheeks 42 , 44 and the core 46 of the fold 40.
- the thickness e min of the plate 14 can be between 50% and 75% of the maximum thickness e max of the In particular, the thickness e m i n of the plate 14 may be greater than 0.8 mm and / or less than 1.2 mm.
- the maximum thickness e max of the plate 14 at the fold 40 may be greater than 1 mm and / or less than 2 mm, in particular be substantially equal to 1.5 mm.
- this maximum e max is the thickness of the plate 14 at the ends of the cheeks 42, 44 of the fold 40, which do not join the core 46.
- the thickness E max may be equal to the thickness of the plate 14 to level of the receiving zones 30, 32, especially in the vicinity of the groove 38.
- Figure 6 illustrates a variant in which the header plate 14 has, on its outer face 14b, a deformation or groove 50 forming a greater thinning.
- the groove 50 is made at the groove 38.
- the groove 50 extends in particular parallel to the groove 38.
- the groove 50 can, by itself, to create a thinning of the collector plate 14 at the fold 40 Alternatively, however, this groove 50 is produced in addition to a thinning as described with reference to FIG. 5.
- the groove 50 and / or any thinning of the plate 14 at the groove 38 is made closer to the receiving zone receiving the tubes of the first bundle of tubes, that is to say the tubes traversed by the hottest fluid, than the receiving zone receiving the tubes of the second bundle of tubes, c that is to say the tubes traversed by the coldest fluid.
- the thinning and / or the groove 50 are not made at the top of the fold 40, but are offset with respect to this vertex, in the direction of the receiving the tubes traversed by the hottest fluid. This facilitates the deformation of the header plate 14 at the groove 38, by rotation around the thinning.
- FIGS. 7 and 8 illustrate in greater detail the mounting of the first cover 22 on the first manifold plate 14.
- a seal 52 is received in the groove 38.
- the seal 52 has a "U" section in order to to be received in the groove 38 and to receive a wall 54 of the first cover 22.
- the wall 54 separates the distribution space, in fluid communication with the water inlet 24, on the one hand, and the first tube bundle, on the other hand, and the collection space, in fluid communication with the water outlet 26, on the one hand, and the second bundle of tubes, on the other hand.
- the seal 54 is preferably the central branch of a gasket 56 at "8".
- the seal 56 may be section "U" to receive walls of the first cover 22 and thus seal these covers.
- the portion of the seal 56, not received in the groove 38 is received in a groove 58, made in the inner face 14a of the header plate 14 and surrounding the first and second receiving zones 30, 32.
- a single first cover forms the inlet and the water outlet of the heat exchange device.
- the water inlet and outlet are formed by separate lids.
