Definitions
- the invention relates to the field of heat exchangers, in particular for a motor vehicle and more particularly to a collector plate of such a heat exchanger.
- the invention is particularly applicable to a mechanical type exchanger comprising a heat exchange bundle comprising tubes and heat exchange elements, called fins.
- the fins are placed parallel to each other and perpendicular to the tubes. In other words, the fins are superimposed on each other.
- the fins are pierced with holes allowing the passage of the tubes, the number of holes being equal to the number of tubes of said row.
- the maintenance of the tube-fin bundle is achieved mechanically by means of a tool, also called olive, introduced inside the tubes so as to deform the walls of the tubes and forcibly apply them against the holes made in the fins.
- a tool also called olive
- the fins are spaced two by two in a separation step, of the order of a millimeter, for example.
- the invention relates more particularly to the collector plates comprising a multiplicity of holes adapted to receive the ends of the tubes of the heat exchanger.
- the ends of the tubes are each inserted into a collector plate provided with openings for receiving the tubes.
- the collector plates are subsequently capped by lids so as to form collector boxes.
- Sealing is thus ensured by controlling the compression of the seal against a collar, surrounding a hole of the collector plate, this control being, however, different depending on whether the tubes are of circular section or of oval or elongated section as it is more and more often the case to improve the performance of the exchangers.
- the object of the invention is therefore to overcome the aforementioned drawbacks by providing collector plates comprising oval or elongated section tubes for which the compression of the seal on the periphery of the oval section of the tube is perfectly controlled so as to perfect the sealing for this tube shape.
- the subject of the invention is therefore a heat exchanger plate capable of receiving a lid of a collecting box of said heat exchanger, said collecting plate comprising at least one hole for the passage of a tube of said heat exchanger, said hole having a periphery provided with a collar, said collar having a height.
- the height of said collar is variable on the periphery of the hole for the passage of said tube.
- the collar may have at least one major axis and a minor axis and may comprise at least a first portion said maximum height and a second portion said minimum height, said maximum height portion being located on the small axis of the collar and said minimum height portion being located on the major axis of the collar.
- the collar may have an intermediate portion between the minimum height portion and the maximum height portion, the height of which progressively changes between the two portions of minimum height and maximum height.
- the neck section may be oval or elongated.
- the invention also relates to a heat exchanger which may comprise a heat exchange bundle provided with at least one such plate collector, said beam may comprise oval or elongate tubes and fins, said fins having holes for the passage of the tubes and being placed parallel to each other, and the tubes being mechanically deformed so as to force them against the holes for the passage of the tubes in the fins.
- the walls of the tubes are deformed to force them against the holes of the fins for the passage of said tubes.
- the heat exchanger may further comprise a seal capable of being applied against said header plate and comprising a flange having substantially the same shape as that of the collar of the collector plate, the flange being inserted into the collar. of the collecting plate.
- FIG. 1 is a schematic general view of a heat exchanger
- FIG. 2 is a partial cross sectional view of a heat exchanger according to the invention.
- FIG. 3 is a sectional view along the line III-III of Figure 2.
- FIG. 4 is a sectional view of the header plate of the heat exchanger of FIG. 2;
- Figure 1 a schematic view of a heat exchanger, for example a cooling radiator of a motor vehicle.
- the mechanical type heat exchanger In other words, it is generally composed of at least one heat exchange bundle 2 comprising tubes 4 arranged parallel to each other and heat exchange elements, called fins 10.
- the fins 10 are placed parallel to each other and perpendicular to the tubes 4. In other words, the fins are superimposed on each other.
- the fins are pierced with holes 18 allowing the passage of the tubes 4, the number of holes 18 being equal to the number of tubes of said row.
- the beam 2 is mounted between two collector boxes 6 and 8.
- Each tube 4 has a free end 12 mechanically assembled to a header plate 14, also called a "collector”, which forms, with a lid, each manifold 6 and 8.
- a header plate 14 also called a "collector” which forms, with a lid, each manifold 6 and 8.
- the ends 12 of the tubes inserted in the collector plate have exactly the same section as the tubes, in the common part receiving the fins 10. After assembly, the ends of the tubes are deformed / flared so as to secure them to the manifold plate 14 and to compress a seal (described later).
- the header plate 14 comprises a core 16 of generally rectangular shape delimiting a multiplicity of holes 18, here of oval or elongate section, adapted to receive the ends 12 of the tubes.
- Each hole 18 is surrounded by a collar 20 directed towards the fins 10, the collars 20 making it possible to increase the contact area between the outer peripheral wall of each of the tubes 4 and the collector plate 14.
- the section of the collars 20 is defined by the contour resulting from a section in a plane substantially transverse to said collars.
- the core 16 is extended by a peripheral groove 22 defining a groove and terminated by a peripheral rim 24 forming foldable legs, also called crimping tabs.
- the header plate 14 receives a compressible seal 26 which is applied to the core 16 of the header plate.
- the seal 26 comprises a multiplicity of flanges 30 which are each introduced into a hole 18 to seal between the end 12 of a tube and the collar 20 corresponding.
- the core 28 forms at its periphery a bead 32 disposed in the channel 22 and adapted to seal with one or other of the covers of the manifolds 6 or 8 when the peripheral flange 24 is folded.
- the end section 12 of the tubes 4 and holes 18 of the header plate 14 have a substantially oval shape characterized by a major axis A and a small axis B.
- the section of the tubes 4 is defined here by the contour of the tubes 4 resulting from a section in a plane substantially transverse to said tubes.
- the invention provides to increase the height of the collars 20 of the collector plate 14 in the areas where the tube 4 offers the least resistance to the compression so as to balance the distribution of compression forces of the seal on the periphery of the section of said tube 4.
- the portions 36 of small axis B are those offering the least resistance to compression of the flanges 30 of the seal 26.
- the tube 4 is less resistant in its minor axis B than in its large axis A.
- Figure 4 illustrates the characteristic shape of the collar 20 of the header plate 14 according to the invention.
- the collar 20 thus has a portion 38 of minimum height H1 facing the portion 34 of major axis A of the tube 4 and a portion 40 of maximum height H2 facing the portion 36 of small axis B of the tube 4.
- An intermediate portion 42 ensures continuity between the portions 38 and 40 of different heights and has a height progressively evolving between the portions 38 of minimum height H1 and 40 of maximum height H2. In other words, one thus creates ends of collars no longer rectilinear or on the same plane as known in the prior art, but collars with a progressive form.
- the major axis A of the tube 4 is 2.5 times greater than the minor axis B, the minimum height H1 of the portion 38 is then equal to 3mm and the maximum height H2 of the portion 40 is equal to 3.5mm.
- the major axis A may be for example 2.8 or 3 times greater than the minor axis B of the tube 4.
- more the section of the end 12 of the tubes 4 is elongated plus the difference between the values of the heights H1 and H2 is important. This ensures an optimum seal between the collars 20 and the ends 12 of the tubes 4, the tube resistant to the force exerted by the compression of the collar 30 of the seal 26.
- the flange 30 of the seal 26 has the same characteristic shape as that of the collar 20.
- the contact surface between the flange 30 of the seal and the tube 4 is thus increased so as to distribute the forces on the periphery as well as possible. said tube.
- the forces applied to the tube thus become compatible with its resistance.
- the invention there is therefore a relatively simple collector plate to achieve, to obtain a uniform distribution of forces on the periphery of the oval or elongated tubes.
- the compression of the joint between the ends of the tubes and the collars of the collector plate is perfectly controlled and its sealing is all the more optimal.
- the shape of the collars of the invention is applicable to any type of collector regardless of the number of ranks for the collector plate bundles.
- the invention is particularly applicable to the realization mechanical type heat exchangers for motor vehicles and in particular for radiators for cooling or heating.
