Definitions

  • the present invention relates to a trunk of a rail vehicle, comprising first and second electrical equipment and a first cooling device capable of evacuating heat dissipated by the first electrical equipment, said first cooling device comprising a fan, said fan comprising a fixed body and a rotary device adapted to circulate a first air flow inside said fixed body.
  • the invention applies to the field of rail transport, including electric traction vehicles, such as locomotives and railcars.
  • traction box means the part of a traction vehicle which is intended to control the traction motors of said vehicle.
  • the cooling device is typically for cooling part of the electrical equipment such as a power module or a transformer.
  • the fan puts the electrical equipment in contact with a flow of air outside the trunk in order to dissipate the heat produced by the equipment.
  • the temperature in the vicinity of these other electrical equipment can thus become too high for optimal operation of said equipment, particularly in the case where the box has an outer envelope sealed to the outside air.
  • the object of the present invention is to allow the cooling of a larger number of electrical equipment of the trunk of the trunk, minimizing the additional cost and bulk.
  • the subject of the invention is a traction box of the aforementioned type, in which: the fan furthermore comprises fins secured to an external surface of said fixed body, and the trunk comprises a second clean cooling device; discharging heat dissipated by the second electrical equipment, the fixed body and the fan blades forming part of said second cooling device.
  • the invention also relates to a railway vehicle comprising at least one traction motor controlled by a traction box as described above.
  • the figure 1 is a schematic front view of a trunk 10 of a rail vehicle, according to one embodiment of the invention.
  • the box 10 comprises a support 12, having for example the shape of a cage consisting of vertical and horizontal bars 14.
  • the bars 14 divide the support 12 into several housings 16, 17 and a ventilation column 18.
  • the ventilation column 18 is disposed over an entire height of the support 12.
  • the ventilation column comprises a lower portion 22 and an upper portion 24, located one above the other .
  • the upper 24 and lower 22 portions of the ventilation column 18 are edged laterally, respectively by one or more upper housings 16 and by one or more lower housings 17.
  • the box 10 comprises a ventilation duct 26 disposed in the ventilation column 18 and vertically passing through said box 10.
  • the duct 26 has an air inlet 28 and an air outlet 30, said inlet and outlet opening to the outside the support 12 and the trunk 10.
  • the inlet 28 and the outlet 30 are respectively located at the upper and lower ends of the support 12.
  • the duct 26 is delimited by a wall 32.
  • the trunk 10 has an outer envelope 34, shown in dashed lines on the figure 1 and in section on the figure 2 .
  • the wall 32 of the ventilation duct 26 and the outer casing 34 are airtight, and the casing 34 is sealed to the ends of the wall 32 forming the inlet 28 and the outlet 30.
  • the air present in the housings 16, 17 is confined inside the trunk 10.
  • An outside air flow circulating between the inlet 28 and the outlet 30 is notably isolated from the indoor air present in the dwellings. 16, 17 adjacent to the ventilation column 18.
  • the housings 16, 17 are not airtight with respect to each other.
  • the trunk 10 further comprises electrical equipment 36, 37, 38.
  • the electrical equipment 36, 37, 38 comprise, for example, circuits for processing an electric current from a source of electrical energy external to the railway vehicle, for example example a catenary.
  • the electrical equipment 36, 37, 38 comprise, for example, traction motor control circuits of the railway vehicle.
  • First and second electrical equipment 36, 37 are respectively arranged in the upper and lower housings 16, 17.
  • Third electrical equipment 38 are located in the lower part 22 of the ventilation column 18.
  • the third electrical equipment 38 is located inside the ventilation duct 26.
  • the box 10 further comprises a fan 40 disposed in the upper part 24 of the ventilation column 18.
  • the fan 40 is shown in section, seen from above, at the figure 2 .
  • the fan 40 comprises a fixed body 42, of cylindrical shape of revolution, disposed along a vertical axis.
  • the body 42 of the fan 40 is part of the wall 32 of the ventilation duct 26.
  • the fan 40 also comprises a ventilation wheel 44 disposed inside the fixed body 42.
  • the wheel 44 is connected to rotating drive means (not shown) so as to generate a flow of air between the inlet 28 and outlet 30 of the ventilation duct 26.
  • the fan 40 and the ventilation duct 26 thus form a cooling system for the third electrical equipment 38.
  • the fan 40 has fins 46, 47 integral with an outer surface of the fixed body 42.
  • the fins 46, 47 have for example the form of flat plates with a square or rectangular contour.
  • the fins 46, 47 are arranged horizontally and stacked one above the other along the vertical axis of the fixed body 42.
  • the fins 46, 47 are spaced from each other along said vertical axis.
  • edges of the fins 46, 47 are in contact with an inner surface of the outer casing 34.
  • two adjacent wings 46, 47 define, with said casing 34, an air circuit 50 which bypasses the body fixed cylindrical 42 of the fan 20.
  • An inlet 52 of each air circuit 50 is located at the edge of an upper housing 16.
  • outlets 54 of all the air circuits 50 formed by the fins 46, 47 open onto a manifold 56, said manifold opening itself into a lower housing 17.
  • the air circuits 50 comprise blowers 58 for circulating the air in said circuits 50.
  • the blowers 58 are for example small mixing fans.
  • the ventilation wheel 44 of the fan 40 is rotated, so as to generate an outside air flow 60 between the inlet 28 and the outlet 30 of the ventilation duct 26.
  • the flow outside air 60 is represented by white arrows on the figure 1 .
  • blowers 58 are put into operation, so as to generate an interior air flow 62 between the inlet 52 and the outlet 54 of each air circuit 50.
  • the interior airflow is represented by colored arrows on the Figures 1 and 2 .
  • each air circuit 50 thus has a temperature lower than that of the inlet air 52.
  • Warm indoor air is thus taken from the upper housings 16 and cooled internal air is reinjected by the collector 56 into the lower housings 17.
  • the inlet air 52 has a temperature close to 70 ° C and the outlet air 54 has a temperature below 60 ° C.
  • the fan 40 - in particular its fins 46, 47 -, the manifold 56 and the blowers 58 thus form a cooling system of the first 36 and second 37 electrical equipment.
  • Such a system also has interest to focus on the fins 46, 47 the phenomenon of condensation inside the trunk 10.
  • the fins indeed represent the coldest point of the device. The condensation is reduced or even eliminated in the rest of the box 10.
  • the cost of adding fins 46, 47, manifold 56 and blowers 58 to an existing trunk is low.
  • the fins 46, 47 take place in the corners of the ventilation column 18 not used by the cylindrical fixed body 42, which minimizes the additional bulk.
