- the invention more specifically relates to a manifold mounted on a heat exchanger, such as a radiator for engine coolant.
- a heat exchanger such as a radiator for engine coolant.
- This type of radiator conventionally uses tubes and spacers arranged between the tubes for the heat exchange bundle while the manifold comprises at least two parts, one forming the manifold plate for receiving and fixing the ends of the tubes. of the exchange beam 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 "all-metal" header box type has a number of advantages over the type of plastic cover header which requires the attachment of a sealing means, typically a resilient seal, to provide a connection perfectly sealed between the cover and the collector plate.
- the header plate has a groove or groove for placing and positioning the seal.
- collector plates do not have groove or groove to facilitate in particular the positioning and the maintenance in place of the seal.
- This collector plate without groove or groove is disclosed and described in EP 1702191 filed by the applicant.
- the present invention aims to remedy the drawbacks of collector plates without throat or groove of the prior art by proposing a solution to achieve optimum fixation between the cover and the collector plate, without damaging the collector plate, its collars or the ends of tubes and ensuring a good positioning of the joint.
- flat surface relative to the collector plate means that this collector plate extends in a single flat surface, with the exception of collars which are conventionally protuberant, in particular at its periphery so that that the collector plate has no groove, structural reinforcement (upwards or downwards relative to the average plane of the collector plate), groove or the like, conventionally used to house the sealing means (conventionally an elastic seal) and which also has the function of reinforcing the collector plate during crimping of the teeth or the like of the latter in order to fix the cover to the collector plate.
- collars which are conventionally protuberant, in particular at its periphery so that that the collector plate has no groove, structural reinforcement (upwards or downwards relative to the average plane of the collector plate), groove or the like, conventionally used to house the sealing means (conventionally an elastic seal) and which also has the function of reinforcing the collector plate during crimping of the teeth or the like of the latter in order to fix the cover to the collector plate.
- the distance between two adjacent openings or collars, or "no tubes” p is between 5 and 8 mm;
- the height of the collars is between 1 and 5 mm, in particular between 1 and 2.5 mm.
- said plate is provided with crimping teeth, provided at its periphery.
- Said teeth are, for example, spaced from each other and give the periphery of the plate a crenellated appearance. They have a dimension 1, called width, taken in a direction oriented parallel to a large side of the plate.
- a density of crimping teeth can be defined as being the ratio between, on the one hand, the cumulative width of the teeth and, on the other hand, the length L of said large side, taken in the rectilinear portion of the latter, c ' is to say, outside the end zones of the plate if it is in the form of a radius.
- the invention also relates to a header box including a header plate, as defined above, and a cover.
- the material thickness of the header plate, or portions forming the header plate is between 0.8 mm and 2 mm, preferably between 0.8 mm and 1.5 mm.
- Said box is provided with a seal, positioned at the periphery of the plate, between said plate and the cover.
- a seal positioned at the periphery of the plate, between said plate and the cover.
- the ratio between ph, p being the "tube pitch”, and h the "tube height” or the dimension of the minor axis of the orifices for the passage of the tubes, on the diameter d of the the seal being between 1 and 3.
- (ph) / d is between 1 and 3, for example between 1.5 and 2.5.
- diameter d of the seal is meant, in case the seal is not round, the diameter of the round joint having the same section.
- the invention finds its application both for brazed heat exchangers and for so-called heat exchangers
- the invention relates to a brazed heat exchanger, in particular for motor vehicles, comprising a heat exchange bundle consisting of a plurality of tubes or the like whose ends are respectively fixed to two manifolds, characterized in that the two collector boxes are as stated above.
- the invention also relates to a heat exchanger, in particular for motor vehicles, comprising a heat exchange bundle consisting of a plurality of tubes or the like whose ends are respectively fixed to two manifolds, the elements constituting said manifold are mechanically fixed to each other, characterized in that the two manifolds are as stated above.
- the exchanger will have at least one of the following characteristics:
- the height h of the tubes is between 1 and 8 mm, in particular between 1 and 5 mm, and preferably between 1 and 2 mm; the lateral edges of the tube ends have a circular or rectangular section;
- the tube material thickness is between 0.15 and 0 y 5 mm, in particular between 0.15 and 0.35 mm, and preferably between 0.15 and 0.27 mm.
- FIG. 1 is a diagrammatic section illustrating a portion of a collector plate of the prior art with its openings or collars intended to receive the ends of the tubes as well as the forces exerted on the collector plate and on its collars or on the ends of the tubes;
- FIG. 2 is a schematic section illustrating a portion of a header plate according to the invention with its openings or collars for receiving the tube ends and the forces exerted on the. collector plate and on its collars or on the ends of the tubes,
- FIG. 3 is a partial sectional view of a collecting plate according to the invention, the section being taken according to the orientation given by the line III-III of FIG. 2, that is to say, according to the longitudinal axis of said plate,
- FIG. 4 is a simplified partial sectional view of a portion of another embodiment of the header plate according to the invention, the section being again made according to the orientation given by the line III-III of FIG. Figure 2.
- Figure 1 shows a partial section of a header plate 1 illustrating the openings or collars 2 for a manifold (also sometimes called "collector") of the prior art. On this figure are also illustrated the forces 3, 3 'acting on the collector plate 1, and as well as on each of the collars or openings 2 present on said plate 1 or on the ends of the tubes.
- the manifold of the invention is a manifold provided with a portion or plate 1 having the function of collecting the ends of tubes; this collecting plate 1 extending in a single plane and having no recess, groove; or any other deformation intended to provide a structural reinforcement since the object of the invention is to disclose a solution, different and advantageous, reinforcing the collector plate 1 and its collars 2 and at the same time that the ends of tubes, in particular during crimping and subsequently to crimping.
- the collecting box is conventionally produced and has no technical particularity distinguishing it, for example, from what is described in EP 1702191 in the name of the applicant.
- the heat exchanger, brazed type or "mechanical" type does not have, in addition to its specific characteristics related to the present invention, features distinguishing it from the prior art.
- the collector box of the prior art comprises collars generally of rectangular, circular or similar shape.
- the distance between two collars 2, corresponding to the pitch p 'of tube, is at least equal to 12 mm.
- this force 3 is applied on the periphery of the collector plate 1 and this force is substantially distributed on the lateral ends 3 'of the collars 2, or on the ends of the tubes, whereas this part of the collars 2 or ends of the tubes is particularly fragile.
- the force 3, 3 'exerted on each of the lateral end portions is large and damages the collector plate 1 or said lateral ends of the collars 2, or the ends of the tubes.
- opening means that there is only an opening 15 in the header plate 10 for receiving a tube 11 as opposed to the notion of collars 12 which correspond to the portion of the header plate 10 going up / down from the middle plane (or surface) XX of the header plate.
- a manifold plate 10 with openings 15 is shown in Figure 3 and a header plate
- Fixing the lid, not shown in the accompanying figures, to the collector plate is made in a manner perfectly known and controlled by those skilled in the art, for example with the aid of teeth 20, illustrated in FIG. 3, provided for this purpose. effect on the collector plate to be crimped on the edges of the lid.
- Said crimping teeth 20 are provided at the periphery of the plate, at a lateral edge 40 thereof, said lateral edge 40 surrounding the flat portion 80, provided with orifices for the passage of the tubes, of the plate. Said teeth are, for example, spaced from each other and give the upper part of the lateral edge 40 of the plate a crenellated appearance.
- Said teeth 20 have, in particular, a dimension, called width 1, taken in a direction oriented parallel to a large side of the plate.
- said plate has a crimping tooth density, defined as being the ratio between, on the one hand, the cumulative width of the teeth and, on the other hand, the length L of said long side, taken in the rectilinear portion of the latter , that is to say, here, without taking into account the rays 50 connecting the lateral 60 and longitudinal 70 parts of the lateral edge 40.
- the density of crimping teeth on the tube pitch is, for example, between 0 , 04 and 0.17.
- a sealing gasket 30 of a manifold of an exchanger according to the invention has been shown in FIG. 3, before being put into compression. It is located on the periphery of the flat plate portion 80, between the ends of the tubes opening into the box and the lateral edge 40 of the plate.
