Definitions
- the invention relates to a heat exchanger tube, particularly for motor vehicles.
- the invention also relates to a heat exchanger comprising a bundle of such tubes.
- the invention relates to the field of heat exchangers, especially for motor vehicles.
- the present invention relates in particular to heat exchangers intended to be arranged on the front face of a motor vehicle.
- a front face also called front panel, is a structural element capable of integrating various equipment of the vehicle, such as headlamps, turn signals, buzzer, heat exchangers, fan motor unit or cooling module.
- the heat exchanger is for example used for cooling the engine or for the air conditioning of the passenger compartment.
- the heat exchangers conventionally comprise a bundle of tubes and collector boxes into which the ends of the bundle tubes open, so as to allow the circulation of a fluid, especially a cooling fluid, in the tubes of the bundle.
- the tubes of such exchangers can be made for example by extrusion.
- this type of manufacturing generates a significant cost, especially because of the need for specific channels for each type of tubes.
- the tubes are made from a web of material, for example, by folding the web of material.
- the heat exchanger tubes can be subjected to many stresses such as a high-speed impact with an object (for example, a gravel) coming from the external environment.
- the tubes of heat exchangers are therefore subjected to external stresses. Since the fluid must not escape from the tubes of the heat exchangers at the risk of compromising the operation of these heat exchangers, it is necessary to maintain the tightness of the tubes between the outside and the fluid.
- a grid usually plastic, can be integrated on the front to stop the chippings.
- the integration of such a grid at the front face generates a certain cost.
- a known solution is to allow the tube to withstand such an impact by locally increasing the thickness of the tube wall when it is an extruded tube.
- such tubes are expensive to manufacture.
- these tubes are less resistant to corrosion compared to tubes made from a strip of material, in particular by folding.
- a first known tube made from a strip of material the end portions of the tube are folded and joined together by brazing, at one side or nose of the tube. Such brazed folds at the end portions require complicated manufacturing.
- such tubes may not be sufficiently resistant to impact with chippings.
- an object of the invention is to propose a solution for a pipe made from a strip of material, providing the tube with improved resistance to external stresses in a simple manner, by at least partially solving the aforementioned drawbacks of the prior art.
- the subject of the invention is a heat exchanger tube made from a strip of material, the strip of material having two end portions connected to form the tube.
- the strip of material forming the tube is folded on itself, so as to define at least one fold formed by two strip portions in continuity of material, such that at least one band portion of the fold:
- - is a protective strip portion of the tube in case of impact of a element outside the tube
- the two portions of strips of said at least one fold can be made in the intermediate portion of the web of material.
- the intermediate portion of the web of material is by definition distinct, i.e., does not include, the lateral ends of the web of material.
- the end portions of the web of material each include a lateral end of the web of material.
- the intermediate portion of the material strip as the central portion corresponding to 80% of the width of the strip of material, the end portions corresponding for example to the parts having a width of 10% on each side of the strip of material. the intermediate part.
- the intermediate portion has a longitudinal extension corresponding to the longitudinal extension of the tube.
- the ply or plies are not made at a connection area or overlapping walls of the strip of material requiring sealing, but the wall is folded on itself in continuity of material. Thus, even if the folds would deform, unfold, the sealing of the tube, also achieved for example by soldering or electrofusion, would remain assured.
- the invention thus has the advantage of protecting the junction between the end portions of the strip of material, and therefore the tightness of the tube.
- Said tube may further comprise one or more of the following features, taken separately or in combination.
- the intermediate portion does not include a junction area between the two end portions to seal the tube.
- the intermediate portion is devoid of such a junction area.
- said at least one fold is formed along at least one lateral side of the tube.
- This side is configured to be arranged on the front side of a heat exchanger facing an inlet of an external air flow on the front face of a motor vehicle.
- the tube has two long sides connected by two small lateral sides. Said at least one fold is formed on a small lateral side.
- the strip portions of said at least one more are brazed together so as to increase the mechanical strength of the tube.
- the band portions of said at least one fold may be leaned or not to each other.
- the strip of material is folded so as to form an outgrowth extending from the tube towards the outside of the tube.
- Such an outgrowth is the first surface of the tube with which, for example, a grit comes into contact in the event of impact.
- the outgrowth can bend and / or deform under the effect of the impact and thus absorb the energy of the gravel.
- the protrusion may have a thickness of at least twice the material thickness of the material web.
- the protrusion forms with the horizontal a non-zero angle, in particular less than or of the order of 45 °, preferably of the order of 30 °.
- the protrusion may extend over a width equal to at least two times and at most ten times the material thickness of the material web.
- the strip of material is folded in the direction of the height of the tube, so as to form an extra thickness of material.
- the height of the strip portions of said at least one fold is for example of the order of the height of the tube.
- the tube is a folded tube.
- the tube may have a substantially "B" cross section, defining two parallel channels of fluid circulation delimited by a partition.
- the tube can be an electrowelded tube

- the tube 5 thus formed then has a variable thickness.
- the tube 5 has one or more reinforced zones, that is to say zones having a greater thickness, obtained by folding the material web 11 on itself. These reinforced areas correspond to the areas of the tube 5 which are the most stressed, in particular, the nose of the tube 5.
- At least one of the strip portions 13a, 13b of the folds 13 forming the extra thickness E ' ensures the protective function of the tube 5 in case of impact of an external element such as a grit. Indeed, this extra thickness E ' also allows to absorb the energy of the gravel in case of impact.
- the folds 13 are made along the entire height h of the tube 5.

- the folding of the strip of material 11 at at least one intermediate portion 11b to form one or more plies 13 can be done before or after electrowelding to form the tube 5. It is therefore understood that with the ( s) fold (s) 13 formed (s) at least at the nose of the tube 5 according to one or other of the embodiments described above, sufficient material is guaranteed at strategic levels so as to withstand efforts, in particular external forces, requesting the tube 5.
- Such tubes 5 may be provided in any type of heat exchanger 1, in particular brazed, such as an engine cooling radiator or a low-temperature radiator, or a condenser of an air conditioning loop.
