    [0001] The present invention relates to a device for cooling at least one component intended to equip a vehicle, in particular a railway vehicle. The invention relates for example to the cooling of electronic components, in particular of brake resistors. Indeed, some rail vehicle braking systems are suitable for generating electrical energy during braking. These braking systems then comprise brake resistors, able to dissipate some of the electrical energy generated during braking. Such brake resistors are usually cooled by a suitable cooling device. Generally, such a cooling device comprises fans and / or at least one heat pump circuit. The present invention is intended in particular to provide a cooling system of electronic components more economical than those existing in the state of the art, while allowing cooling at least equally effective. For this purpose, the invention particularly relates to a cooling system of at least one component, intended to equip a vehicle, in particular a railway vehicle, characterized in that: - the device comprises a housing, intended to be arranged on a roof of the vehicle, said housing comprising two side walls and an upper wall, defining together a housing for each component, each housing forms an air guide duct in which is housed the corresponding component, said duct extending between less an air inlet side opening formed in one of the side walls and an upper air outlet opening formed in the upper wall. As the vehicle moves, air rushes through each inlet side opening, and flows through the guide duct to the outlet opening. Since the component is arranged in this air guide duct, the air flows in this duct in contact with this component, thereby exchanging heat with this component in order to cool it. Thus, the cooling system according to the invention does not require a fan or a heat pump, so that it has a lower manufacturing cost than the cooling systems of the state of the art, and no Energy is not specifically spent on cooling the component, which allows additional savings.
    [0002] A cooling device according to the invention may further comprise one or more of the following characteristics, taken alone or in any technically feasible combination: - Each lateral opening of the air inlet is arranged opposite the corresponding component. - Each upper air outlet opening is arranged opposite the corresponding component. - The housing has, for each component, two lateral air inlet openings, each formed on a respective side wall. - Each upper opening has a shape symmetrical with respect to a respective median plane perpendicular to the upper wall and the side walls. - Each side opening has a shape symmetrical with respect to a respective median plane perpendicular to the side wall and the upper wall. Each air guide duct comprises, for each lateral opening, an upstream part prolonging this lateral opening towards the corresponding component, this upstream part being delimited by substantially planar upper and lower surfaces, and converging front and rear surfaces converging towards each other since the lateral opening towards the component. - The upper wall comprises, for each upper opening, at least one deflector element, projecting from the upper wall, and extending along a front or rear edge of the upper opening, perpendicular to the side walls . - The upper wall comprises, for each upper opening, two baffle elements, extending respectively along the front edge and the rear edge of the upper opening. The invention also relates to a railway vehicle, comprising a roof, characterized in that it comprises a cooling device as defined above, arranged on said roof, for example in a housing formed in said roof.
    [0003] The invention will be better understood on reading the description which follows, given solely by way of example and with reference to the appended figures in which: FIG. 1 is a perspective view of a railway vehicle comprising a cooling device according to an exemplary embodiment of the invention; - Figure 2 is an enlargement of the cooling device fitted to the railway vehicle of Figure 1; - Figure 3 is a perspective view of the cooling device of Figure 2, partially shown, and some walls are shown in transparency. FIG. 1 shows a railway vehicle 10 comprising a cooling device 12 according to an exemplary embodiment of the invention.
    [0004] In the present description, the terms "front" and "rear" are defined according to the direction of movement of the railway vehicle. Such a railway vehicle is usually able to move in two opposite directions, so that the front and rear of the vehicle can be reversed depending on the direction of travel. The rail vehicle 10 conventionally comprises at least one component 14 to be cooled, for example at least one electronic component, in particular a resistor or a set of brake resistors. Said cooling device 12 is intended for cooling each component 14. In the example shown, as shown in FIG. 3, the cooling device 12 is designed to cool three groups of components 14.
    [0005] The railway vehicle 10 comprises at least one car provided with a roof 16, on which the cooling device 12 is arranged. For example, when the railway vehicle 10 comprises several cars, the cooling device 12 is arranged on the roof 16 of the vehicle. a driving car of this railway vehicle 10. Advantageously, said roof 16 comprises a housing 18, in which the cooling device 12 is housed, so that this cooling device 12 does not extend, or little, protrude from above this roof 16. As shown in Figures 2 and 3, the cooling device 12 comprises a housing 20, comprising side walls 22 and an upper wall 24. In the example shown, the housing 20 also includes inclined intermediate walls 26, each extending transversely between a respective side wall 22 and the upper wall 24. The housing 20 is housed in said housing 18, so that the upper wall 24 is substantially flush with the roof 16 of the railway vehicle. The housing 20 delimits a housing 28 for each component or group of components 14. For example, as shown in particular in FIG. 3, two adjacent housings 28 are separated by a leaktight wall 30 perpendicular to the top wall 24 and to the side walls. 22. Each housing 28 has at least one lateral inlet opening 32 formed in one of the side walls 22, and an upper air outlet opening 34 formed in the upper wall 24.
    [0006] Each housing 28 then forms an air guide duct, in which is housed the component or corresponding group of components 14, extending between each inlet side opening 32 and the upper outlet opening 34. Advantageously, each housing 28 has two lateral air inlet openings 32, each formed in a respective side wall 22, therefore on either side of the component or group of components 14 housed in this housing 28. Preferably, each inlet opening air 32 is arranged opposite the corresponding component or group of components 14, and each air outlet opening 34 is formed above the corresponding component or group of components 14, facing it. The air flows flowing in the housing 28 therefore pass directly from the air inlet openings 32 to the air outlet opening 34, passing through the component or group of components 14. It should be noted that, in the case of a railway vehicle, the cooling device 12 must be able to operate irrespective of the direction of circulation of the railway vehicle. For this purpose, each upper opening 34 has a symmetrical shape with respect to a respective median plane perpendicular to the upper wall 24 and the side walls 22. Similarly, each lateral opening 32 has a symmetrical shape with respect to a respective perpendicular median plane to the side wall 22 and the upper wall 24. These symmetrical shapes make it possible to ensure the same operating efficiency of the cooling device 12, regardless of the direction of movement of the railway vehicle 10. Advantageously, each guide duct of air 28 comprises, for each inlet side opening 32, an upstream portion 36 extending this lateral opening 32 to the corresponding component 14. This upstream portion 36 is delimited by upper surfaces 36A and lower 36B substantially flat and parallel to each other, and curved front and rear surfaces 36C converging towards one another from the lateral opening 32 towards the component 14. Thus, the upstream portion 36 has a shape favoring the taking of speed of the air flows, which makes it possible to optimize the cooling of the component 14. Moreover, the upper wall 24 is provided, for each upper opening 34, with at least one deflector element 38 projecting from this upper wall 24, and extending along a front or rear edge of this upper opening 34, perpendicular to the side walls 22. Each deflector element 38 has for example a triangular section.
    [0007] More particularly, so that the cooling device 12 has the same optimum operation irrespective of the direction of movement of the railway vehicle, each upper opening 34 is provided with two deflector elements 38, extending one along the front edge and the other along the rear edge of the upper opening 34. The deflector element 38 extending along the front edge makes it possible to deflect the air flowing along the roof 16 of the railway vehicle 10, so that this air circumvents the upper opening 34 and does not enter the housing 28 through this upper opening 34. This deflector element 38 also makes it possible to generate a depression above the upper opening 34, promoting the circulation of the air flows in the guide duct 18, from the inlet side openings 32 to the upper outlet opening 34. It should be noted that the invention is not limited to the embodiment previously described. crit, but could present various alternatives within the scope of the claims.
    [0008] In particular, the cooling device 12 could be intended for cooling other components. In addition, the cooling device 12 could equip another type of vehicle, for example road or air. In this case, it is not necessary to provide a symmetrical operation of the cooling device.
