Definitions
- the invention relates to the field of heat exchangers, especially a motor vehicle.
- collectors based aluminum such heat exchangers comprising a external face coated with external plating and a multiplicity openings each to receive one end of the tube of predefined section and covered externally with external plating.
- the joining tubes relative to the collector is carried out level of 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 because cutting.
- An object of the invention is therefore to propose a collector of the type described in the introduction which does not present the aforementioned drawbacks.
- the invention proposes for this purpose an aluminum-based collector each opening of which is made by puncturing then shaping of a selected and stamped area so that the external face of the collector defines a collar in this zone of internal cross section substantially identical to the predefined section of the end of a tube, allowing thus, after insertion of the tube into the opening of the collar, to obtain surface contact between the external veneers the collar and the end of the tube.
- Puncture is understood to mean a specific punching, in principle without material removal, which facilitates the realization collar, thus obtaining an excellent seal sealing 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 for example 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 for example 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 strengthens the mechanical strength of the collector, compared to an aluminum collector pure.
- an intermediate cladding made, for example, in a aluminum and zinc alloy.
- Such an intermediate plating makes it possible to limit, or even stop, the diffusion of magnesium towards the external plating, thus helping to further strengthen the quality of the seal sealing obtained by brazing.
- the puncture is a punching without removing material, which prevents not damage the external cladding at the openings.
- 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 achieve on said internal face a first relief imprint of dimensions substantially equal to those of the body of the punch, then a second part, on the side of the internal face of the collector, so as to produce on said external face a second relief imprint surrounding at least part of the first impression.
- 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 or its opening (s), 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.
