Definitions
- the invention relates to an assembly of a manifold to aluminum base and tubes for heat exchanger, collector comprising an external face coated with a plating external and a multiplicity of openings suitable for receiving each one end of one of the tubes of predefined section and externally covered with an external veneer.
- the document DE 41 29 573 A describes an assembly of this type, in which the openings are each surrounded by a collar, which provides surface contact between the collar and the tube it receives. However, this document does not provide any details on how the openings are made and the corresponding collars.
- document US-A-4 234 041 describes a collector in which are formed openings each surrounded by a collar.
- each of the openings is made with material removal. More specifically, we train first two spaced cuts, then we execute a slit between the two cuts, which makes it possible to produce two segments which are then forced outwards to form two walls opposite sides of the collar.
- the joining tubes relative to the collector is carried out at the level openings by welding or brazing.
- the openings of this type of collector are generally made by cutting, with removal of material.
- the contact between the end of a tube, coated with an external cladding, and the collector, therefore takes place on the periphery of the opening in which said end is introduced.
- the contact is therefore made at the thickness of the wall of the collector, which is not coated with plating due to the cutting.
- An object of the invention is therefore to propose an assembly of the type described in the introduction which does not have the disadvantages supra.
- the invention proposes for this purpose an assembly of a collector based on aluminum and tubes, in which each opening is punctured without removing material then shaping a selected area of the collector, which area is stamped with so that the external face of the collector delimits in said zone a collar of substantially identical internal cross section at the predefined section of the end of one of the tubes, so that, after insertion of the tube into the opening of the collar, a surface contact between the respective external veneers of the collar and the end of said tube is obtained.
- Puncture without removing material means punching particular which facilitates the realization of the collar, allowing thus obtaining an excellent seal by brazing.
- the external plating of the collector and of the end of the tube are aluminum alloys and silicon.
- the internal face of the collector which is opposite its external face, is coated with an internal plating, such as an alloy of aluminum and zinc whose anti-corrosion properties are well known. This contributes to strengthen the protection of the heat exchanger against corrosion.
- an internal plating such as an alloy of aluminum and zinc whose anti-corrosion properties are well known. This contributes to strengthen the protection of the heat exchanger against corrosion.
- the collector is made of an aluminum and magnesium alloy, the percentage of magnesium preferably being greater than 2%. This significantly enhances the mechanical strength of the collector, compared to a pure aluminum collector.
- a intermediate cladding made, for example, from an alloy aluminum and zinc.
- Such an intermediate plating makes it possible to limit, even stop, the diffusion of magnesium towards the external plating, contributing thus further enhancing the quality of the seal obtained by soldering.
- step a ') in which the chosen area is stamped, with a first part, on the side of the external face of the collector, so as to make a first impression on said internal face in relief of dimensions substantially equal to those of the body of the punch, then secondly, on the side of the internal face of the collector, so as to produce on said external face a second raised imprint surrounding at least part of the first imprint.
- a collector To make a collector according to the invention, one starts from a substantially flat, aluminum-based plate 1.
- the internal face 4 is also coated with a internal plating, anti-corrosion, such as an alloy aluminum and zinc.
- a internal plating, anti-corrosion such as an alloy aluminum and zinc.
- This first raised imprint 7 has dimensions substantially equal to the dimensions of a tube end 8 (see figure 3), and a punch (see figure 2) intended for make openings 17 to which we will return more far.
- the first imprint 7 is of substantially oval shape long side (longitudinal) L and short side (transverse) l.
- the length L 'of the longitudinal extension of the second footprint is significantly larger than L.
- the first and second fingerprints can be performed in a single step using a suitable machine tool.
- FIG. 1D we use another tool 11 comprising at least one punch 10 (in FIG. 1D, two punches are illustrated), as well as a matrix 12 in which are made as many holes 13 as there are punches 10 provided, said holes 13 being arranged to allow the punches to slide 10.
- Each punch 10 includes a tapered end portion and cutting edge 14 extended by a body 15 of cross section substantially identical to the shape of the first impression 7, as well as to the external cross section of a tube end 8.
- Each hole 13 of the matrix 12 has a shape adapted to that of the body 15 of a punch 10, but slightly higher for reasons which will be explained later.
- the plate 2 is punctured, without removing material, which drafts future openings 17.
- the central part 6 of the collector 1 is then provided with its openings, and consequently the ends 8 of tubes can be introduced into them, as illustrated on Figure 3.
- This surface contact is made over several millimeters high, which allows, during the brazing step, to obtain a very effective seal.
- FIGS. 4A and 4B we now refer to FIGS. 4A and 4B to describe a manifold variant according to the invention.
- these collectors in pure aluminum can be made of an alloy aluminum and magnesium.
- the percentage of magnesium is chosen greater than 2%.
- This type of collector offers resistance characteristics significantly superior to those presented by collectors in pure aluminum.
- the magnesium contained in the alloy tends to diffuse, during the soldering step, in the direction, in particular, external cladding 3, which tends to decrease the effectiveness of the seal at the solder joint, by reducing the wettability of the outer plating of the external side 2. It is therefore preferable to place between the outer cladding 3 and the aluminum alloy plate and magnesium forming the collector 1, a plating intermediate 20 made of an alloy of aluminum and zinc whose physical characteristics allow limit, or even completely stop, the dissemination of magnesium towards the outer plating 3.
- a collector has been described in which the openings are performed after first and second training fingerprints. But these fingerprints are not essential.
