Definitions

  • the invention relates to the field of lighting and/or light signaling, in particular for motor vehicles. More particularly, the invention relates to the cooling of light modules of a motor vehicle headlamp.
  • the light sources present in projectors and lighting devices are subject to overheating and often require cooling. This is particularly the case for semi-conductor light sources, such as light-emitting diodes or even laser diodes. These light sources are in fact of very small size for a high lighting power. They are usually arranged on a plate of the printed circuit type and are often thermally coupled to one or more radiators.
  • the published patent document DE 10 2007 043 961 A1 discloses a projector comprising several light modules whose light sources of the semiconductor type are coupled to radiators. These are cooled by a forced air current through a duct.
  • the latter comprises a cooling air inlet set in motion by a fan, several outlets opening out near the coolers and a passage connecting the inlet to the outlets.
  • the passage includes branches dividing the air flow from the inlet into several flows to the different outlets.
  • the construction of the duct is conventional in that it is the ramifications of the duct which carry out the distribution of the inlet air flow.
  • the number of possible outputs is however limited by the ramifications and, moreover, the distribution of the specific bit rates of the various outputs lacks control. Indeed, an unidentified pressure drop downstream in one of the ramifications can have a significant negative influence on the flow distribution.
  • the realization of the ramifications is not without posing certain problems of size and cost of realization.
  • the patent document FR 2 946 730 A1 discloses, similarly to the previous document, a headlamp for a motor vehicle, comprising several modules whose light sources are cooled by a flow of cooling air circulating through a duct arranged between a fan and respective radiators of the light sources. Similar to the conduit of teaching above, the duct is made to have a bulky and complex shape from a production cost point of view. The distribution of the flow rates has the same drawbacks there as in the previous teaching.
  • the patent document US 2011/0051453 A1 discloses a headlamp for a motor vehicle, comprising several light modules whose light sources are in thermal contact with a common radiator.
  • a fan is arranged in a low position and at a distance from the radiator in order to allow the pivoting of the light sources and of the radiator in relation to a directional lighting function.
  • the object of the invention is to propose a solution to the problem of cooling light modules of a projector or light device. More particularly, the object of the invention is to allow efficient distribution of a flow of cooling air produced by one or more radiators.
  • the subject of the invention is a headlamp for a motor vehicle, as defined in claim 1, comprising: several light modules; an air duct for cooling the light modules, with at least one inlet for an air flow from one or more fans, several air outlets towards the light modules, and a passage connecting the inlet(s) with the exits ; remarkable in that the duct comprises at least one added wall separating the passage.
  • added wall is meant a separate wall of the body of the duct, the wall then being fixed to said body.
  • the body advantageously forms the outer walls of the duct.
  • the passage advantageously forms several fluid veins, such as for example at least four fluid veins.
  • Each fluid stream is advantageously associated with one or more outlets.
  • the conduit is advantageously made of plastic material, in particular thermoplastic.
  • the or at least one of the added walls is adjacent to the inlet or at least one of the inlets.
  • the duct generally extends in a plane, the or at least one of the added walls being parallel to said plane or forming an angle of less than 15°, preferably less than 10°, with said plan.
  • the or at least one of the added walls is configured to divide the air flow, preferably at the inlet of said duct, into at least two separate veins towards the different outlets.
  • the added wall or walls cooperate with one or more fixed partition walls so as to divide the air flow, preferably at the inlet of said duct, into at least four separate veins towards the different exits.
  • the fixed partition(s) are transverse, preferably perpendicular, to the added wall(s).
  • the duct comprises at least two hollow parts assembled together, the or at least one of the added walls being placed between said hollow parts.
  • the added wall or walls are thus sandwiched between the at least two hollow parts.
  • the at least two hollow parts delimit in a complementary manner the passage between the inlet or inlets and the outlets, along one or more cross sections of said passage.
  • the at least two hollow parts form at least one hinge connecting them and making it possible to bring them together with a view to assembling them, said hinge being preferentially integral with said hollow parts.
  • the at least two hollow parts are assembled in generally planar mutual contact, the or at least one of the added walls extending parallel to said plane or forming with said plane an angle of less than 15° , preferably less than 10°.
  • the at least two hollow parts delimit the inlet or at least one of the inlets, along a cross section of said inlet or inlets.
  • each of the outlets is integrally formed on one of the at least two hollow parts.
  • At least one, preferably each, of the outlets forms a channel extending transversely to the duct.
  • the channel formed by the outlet or outlets has a section with a convergent profile.
  • each of the at least two hollow parts comprises a bottom wall, the or each of the fixed partition walls extending over one of said bottom walls.
  • each of the at least two hollow parts comprises side walls, the or each of the fixed separating walls being in contact with at least one of the side walls.
  • the fixed partition walls comprise at least one partition wall transverse to the duct, with an edge adjacent to an edge of the or one of the added walls, said partition wall(s) preferably being generally straight.
  • the fixed partition walls comprise at least one guide wall extending along the duct, said guide wall(s) preferably being curved.
  • the partitioning wall or walls are on one of the at least two hollow parts of the conduit and the or at least one of the guide walls is on another of said at least two hollow parts.
  • the measures of the invention are advantageous in that they make it possible to produce a conduit forming several streams towards different outlets, which is efficient and economical.
  • the duct performs well in that the fact of providing at least one separating wall which is attached makes it possible to separate the fluid streams in an optimal manner.
  • the duct is economical to produce in that all of its fixed walls can extend in the same direction, which is favorable to the stripping operations. The added wall(s) can thus cooperate with the walls fixed to delimit in a precise and controlled manner the different fluid streams towards the different outlets.
  • THE figures 1 to 3 illustrate a projector according to a first embodiment of the invention.
  • FIG. 1 illustrates projector 2 from a front perspective.
  • Headlamp 2 is shown without closing lens. It comprises a casing 4 housing light modules 6, in this case four light modules.
  • the casing 4 also houses a system for cooling the modules 6, more precisely the light sources of the modules in question, comprising a cooling air duct 8 and two fans 10 and 12 connected in an aeraulic manner with the duct 8.
  • the latter comprises air outlets arranged near the radiators of the light modules 6.
  • FIG. 2 is a rear view of the 6 light modules and their cooling system.
  • the two fans 10 and 12 can be observed there arranged in front of corresponding inlets of the duct 8.
  • the modules 6 each comprise a radiator 14 arranged at the rear.
  • the light source(s) of each of the modules 6 are thermally connected to the radiator of the module, so that the cooling air flow of the conduit 8, along the radiators provides cooling of the light source(s) in question.
  • the light sources are advantageously of the semiconductor type, such as for example electroluminescent diodes or else of the laser type.
  • FIG. 3 There picture 3 is a plan view of conduit 8, the latter consisting of two hollow parts 8 1 and 8 2 which are shown in the open state. More specifically, these two parts 8 1 and 8 2 are interconnected by a hinge 8 3 .
  • the hollow parts and the hinge are advantageously made in one piece from a plastic material.
  • Each of the two hollow parts 8 1 and 8 2 comprises two inlets 16 1 /16 2 and 18 1 /18 2 . It is understood that the inputs 16 1 and 16 2 , and the inputs 18 1 and 18 2 , cooperate with each other when the two hollow parts 8 1 and 8 2 are assembled together, to form the inlets 16 and 18 of the duct cooperating with the fans 10 and 12 ( figure 2 ), respectively.
  • the hollow part 8 2 comprises the four outlets 20 1 , 20 2 , 20 3 and 20 4 intended to be arranged close to the radiators 14 of the modules 6 ( figure 2 ).
  • Line 8 thus forms a passage connecting inputs 16 and 18 to outputs 20 1 , 20 2 , 20 3 and 20 4 .
  • the passage is divided into four veins 22 1 , 22 2 , 22 3 and 22 4 specific to the four outlets 20 1 , 20 2 , 20 3 and 20 4 , respectively.
  • the vein 22 1 actually connects the inlet 16 (16 1 +16 2 ) to the outlet 20 1 .
  • the vein 22 2 connects the inlet 18 (18 1 +18 2 ) to the outlet 20 2 .
  • the vein 22 3 connects the inlet 18 to the outlet 20 3 and the vein 22 4 connects the inlet 16 to the outlet 20 4 .
  • Each of the inlets 16 and 18 is thus connected to two veins 22 1 and 22 4 , and 22 2 and 22 3 , respectively.
  • the duct 8 comprises a separation wall 24 (shaded area) arranged close to the inlets 16 and 18 and essentially in the contact plane of the two hollow parts 8 1 and 8 2 .
  • This separating wall is attached in that it is arranged between the two hollow parts 8 1 and 8 2 , this wall being separate from said hollow parts.
  • the added partition wall 24 thus makes it possible to divide each of the two air flows forced into the inlets 16 and 18 by the fans into two fluid streams, in this case the fluid streams 22 1 and 22 4 for the inlet 16 and the fluid veins 22 2 and 22 3 for the inlet 18.
  • the fluid streams are delimited thanks to the fixed separation walls 26 1 , 26 2 , 28 1 , 28 2 , 28 3 , 28 4 and 28 5 of the two hollow parts 8 1 and 8 2 .
  • These fixed partition walls extend generally perpendicular to the mean contact plane of the two hollow parts and, therefore, of the added wall 24.
  • the added wall 24 cooperates with the two walls 26 1 and 26 2 with a view to delimiting, in the hollow part 8 2 , veins 22 1 and 22 2 .
  • the two walls 26 1 and 26 2 have their free edges adjacent to two opposite edges of the added wall 24, respectively. Among the two other edges of the added wall 24, one is adjacent to a side wall of the hollow part 8 2 , along the hinge 8 3 , and the other is located in the entrances 16 and 18 and forms a dividing edge of the flows of these inlets.
  • the hollow parts 8 1 and 8 2 each comprise a bottom wall and side walls, said walls forming a U-shaped profile.
  • the fixed partition walls extend over the bottom walls and are contiguous with the corresponding side walls .
  • the fixed separation walls there are the walls 28 1 and 28 2 on the hollow part 8 2 , of generally curved shape and ensuring appropriate guidance of the fluid streams 22 1 and 22 2 towards the outlets 20 1 and 20 2 .
  • the wall 28 3 still on the hollow part 8 2 , of generally curved shape and ensuring appropriate guidance of the fluid stream 22 3 towards the outlet 20 3 .
  • the fluid stream 22 3 extends, downstream of the added wall 24, over the entire thickness of the duct 8, that is to say in the two hollow parts 8 1 and 8 2 .
  • the fixed wall 28 4 on the hollow part 8 1 cooperates with the fixed wall 28 3 .
  • the fixed wall 28 4 also cooperates with the attached wall 24 in that it comes into contact with the latter.
  • the fixed wall 28 5 on the hollow part 8 1 , also cooperates with the added wall 24 . reported 24.
  • each of the inlets 16 and 18 has a portion of the edge separating the added wall 24, these edge portions ensuring the separation in two of each of the flow rates at the said inlets.
  • each of the flow rates produced by fans 10 and 12 figure 1 And 2
  • the installation of the added wall 24 is particularly simple.
  • the production of the hollow parts 8 1 and 8 2 is also advantageous in that they can be produced in one piece by plastic injection into a mould.
  • the walls delimiting the duct and the fixed partition walls essentially all extend in the same direction, which is favorable to the stripping operations.
  • the added wall 24 can be glued or more simply deposited in a housing on the hollow part 8 2 .
  • the two hollow parts 8 1 and 8 2 can be assembled together by clipping, gluing and/or screwing.
  • THE figures 4 to 6 illustrate a cooling air duct according to a second embodiment, it being understood that this duct can be implemented in a headlight as illustrated in figure 1 .
  • the reference numbers of the first embodiment are used to designate the same elements or corresponding elements, these numbers being however increased by 100 for purposes of distinguishing between the two embodiments. Reference is also made to the description of these elements in relation to the first embodiment. Specific numbers are used for elements specific to this embodiment.
  • the conduit 108 consists, similarly to that of the first mode, essentially of two hollow parts 108 1 and 108 2 interconnected by a hinge 108 3 .
  • the duct 108 has a single inlet 116 (116 1 +116 2 ) for a single fan 110.
  • Each of the hollow parts 108 1 and 108 2 comprises a fixed partition 126 3 and 126 4 , respectively, extending along the axis of the inlet.
  • These two walls 126 3 and 126 4 are advantageously aligned, it being understood, however, that they can also be offset.
  • the added partition wall 124 extends transversely to the walls 126 1 , 126 2 , 126 3 and 126 4 .
  • the walls 126 1 , 126 2 and 126 4 delimit, with the attached wall 124, the veins 122 1 and 122 2 in the hollow part 108 2 .
  • the walls 126 3 , 128 4 and 128 5 delimit, with the attached wall 124, the veins 122 3 and 122 4 in the hollow part 108 1 , at the height of the added wall 124, and in the hollow parts 108 1 and 108 2 , downstream of said wall 124.
  • the conduit outlets may form channels extending transversely to the general extent of the conduit. These channels may have a converging section intended to ensure an acceleration of the flow of cooling air.
