Definitions

  • the invention refers to a car body arrangement with an air duct system of a vehicle, in particular a rail vehicle.
  • Air ducts are used for heating, ventilation, and air conditioning (HVAC) to deliver and remove air to and from a vehicle.
  • HVAC heating, ventilation, and air conditioning
  • the air ducts used for delivering the air to a desired position in the vehicle are normally located in the ceiling area for providing fresh air from above down to the passengers.
  • the air duct systems are often mounted between the car body roof and the interior ceiling and are independent from the car body or ceiling.
  • the air duct system and secondary chambers of the air duct system are supported and connected by multiple brackets to the extrude profiles of the car body roof. The same concept of fixation applies for the ceiling, the lighting and sometimes the roof wire duct(s).
  • the patent application EP 2 335 954 A1 describes an arrangement to be fixed to a roof of a vehicle.
  • the arrangement includes supporting structures fastened to a vehicle body- roof, and a ceiling lining suspended on the supporting structures.
  • the ceiling lining includes a channel module, which forms an air supply channel for supplying air into the interior of a vehicle body.
  • a plate-like ceiling element downwardly covers the air supply channel and forms a surface of the ceiling lining on a lower side. The surface of the ceiling lining is viewed from a passenger compartment.
  • the document CN 202295004U describes an air duct system similar to the air duct system of EP 2 335 954 A1 .
  • the Chinese document refers to a vehicle roof assembly and a passenger vehicle including the roof assembly.
  • the vehicle roof assembly includes a bearing device and a ceiling lining plate.
  • the ceiling lining plate includes a channel module forming an air supplying channel.
  • the bearing device is provided with a fixing component suitable for mounting a display or a monitoring device.
  • the document KR 100765270 B1 refers to a diagonal-type air conditioner duct module including a primary duct supplying cooled air in the longitudinal direction of a passenger room of a train.
  • a secondary duct is formed at two sides of the primary duct to allow the cooled air supplied from the primary duct to pass through a plate having primary exhaust holes such that the cooled air has uniform pressure.
  • a tertiary duct is formed below the secondary duct to allow the cooled air supplied from the secondary duct to pass through a plate having secondary exhaust holes such that the cooled air has uniform pressure.
  • a cooled air exhaust port is formed on the lower portion of the tertiary duct to allow the cooled air to be uniformly supplied to the passenger room.
  • the document JP 09-136648 describes a railway rolling stock.
  • An air duct for fresh air is formed in a car body structure.
  • An air duct forming member is extended in the back and forth directions of the car while its both side end parts are fixed to the vehicle car structure and a vehicle car floor.
  • a car body arrangement for a vehicle in particular a rail vehicle
  • the car body arrangement includes a car body roof having an inner side and an outer side.
  • the car body roof separates an interior of the vehicle from an exterior of the vehicle.
  • the car body arrangement further includes a main air duct arranged at least partially on the outer side of the car body roof; and at least two secondary air ducts, which are spaced apart from each other and form structural parts of the car body roof.
  • a part of the car body roof extends between the two secondary air ducts and connects them. Both of the two secondary air ducts provide air channels between the main air duct and the interior of the vehicle.
  • the design of the car body arrangement including the car body roof allows for integrating at least a part of the air duct system in the car body roof. Therefore, the car body arrangement according to embodiments described herein allows for reducing the weight of the air duct system, and, thus, the whole car body arrangement. Also, the car body arrangement according to embodiments described herein reduces the space required for the air duct system, especially in the interior of the vehicle. The car body arrangement according to embodiments described herein therefore offers more space in the interior of the vehicle or allows for designing the roof construction to be lower than in known vehicles.
  • a further advantage of the car body arrangement according to embodiments described herein is the reduction of material used for forming the car body arrangement with the car body roof and the air duct system according to embodiments described herein. The installation time may also be reduced due to the reduction of single parts to be assembled when mounting the car body arrangement.
  • the car body roof is positioned between the main air duct (at the outside) and the interior passenger ceiling.
  • This arrangement facilitates the integration and connection of additional systems (such as lighting devices, stanchions, LEDD, wire ducts and the like) to the car body.
  • Integrating the secondary air duct chamber into the car body roof (which is e.g. made of aluminum extrude profile) and making it a structural part of the car body roof, may allow for removing (at least some of) the brackets holding the air duct system and, thereby, further save installation time and costs as well as material and weight.
  • the secondary air ducts are separated from the main air duct by respective partition walls.
  • the partition walls may include first openings to provide a fluid connection between the main air duct and the secondary air ducts.
  • the secondary air ducts are connected with the interior of the vehicle by respective second openings. The air flow is thus properly directed from the main air duct via the secondary air ducts to the interior of the vehicle. Further, this arrangement allows for guiding the air flow in a simple way.
  • the secondary air ducts extend at least partially to the exterior with regard to the car body roof. This arrangement may help to further reduce the space for the air duct system required in the interior of the vehicle. With less space occupied by the air duct system in the interior of the vehicle, the gained space may for instance either be used otherwise, the optical appearance in the interior of the vehicle may be improved, or the height of the train may be reduced and the height of the ceiling may be increased.
  • the part of the car body roof which extends between the two secondary air ducts, forms together with the secondary air ducts a continuous internal surface of the car body roof, especially a planar surface.
  • the continuous surface in the interior of the vehicle is useful for providing and/or fixing additional components for the vehicle to the continuous surface.
  • the continuous surface may facilitate and reduce the design of the fixation elements used for fixing additional components to the continuous surface in the interior of the vehicle.
  • the main air duct may cover the secondary air ducts and may extend over the secondary air ducts. Such a design saves space and allows for guiding the air flow in a proper way to the interior of the vehicle.
  • the car body arrangement may further include a cover for the main air duct for improving the aerodynamic conditions of the car body arrangement.
  • the main air duct being located and fixed to the outer side of the car body roof may be covered so as to improve the aerodynamic characteristics of the car body arrangement.
  • one cover may be used for covering the whole main air duct.
  • covers for the left and right side of the main air duct may be provided for improving the aerodynamic conditions.
  • the geometry of the main air duct may be adapted to fit the aerodynamic and aesthetic requirement (e.g. by making the left and right corners of the main air duct "rounded").
  • the car body arrangement described herein may include an interior ceiling system.
  • the interior ceiling system may include at least one component being directly connected to the inner side of the car body roof.
  • the component being directly connected to the inner side may be a ceiling cover for the inner side, a lighting system and/or a roof wire duct.
  • the interior ceiling system allows for easily including and mounting additional vehicle components in the vehicle. Due to the construction of the car body arrangement according to embodiments described herein, the interior ceiling system can directly be attached to the inner side of the car body roof, which facilitates the assembly of the interior ceiling system.
  • the interior ceiling system or single components of the interior ceiling system are connected to the inner side of the car body roof by a C-profile.
  • a ceiling cover, a lighting system and a roof wire duct may be directly connected to the inner side of the car body roof by C-profiles. Mounting the components by a C-profile to the car body roof presents an easy way to mount these components in a vehicle, while, at the same time, the fixation is a low cost solution.
  • the main air duct comprises two units, each being connected to a fan.
  • each unit of the main air duct has a cross-section decreasing in size with increasing distance from the fan.
  • the partition of the main air duct enables a uniform air distribution at each side of the vehicle, such as a uniform air distribution for each passenger compartment in a car.
  • the two units of the main air duct provide a separated and reliable solution. With each unit being connected to a fan, the air flow can be reliably and flexibly guided to the interior of the vehicle. Two smaller fans may be used instead of one large fan. Also, if one of the units fails, the other unit may still operate and supply air to the interior of the vehicle.
  • the secondary air ducts include substantially vertical fins for directing the air from the main air duct to the interior of the vehicle.
  • a reliable and flexible air flow distribution may be achieved by using substantially vertical fins in the secondary air ducts.
  • the secondary air ducts are formed from extruded profiles, especially square or rectangular profiles. Forming the secondary air ducts from extruded profiles allows for producing the secondary air duct in a cost-efficient and easy way.
  • the secondary air ducts may be made from extruded aluminum profiles.
  • the secondary air ducts are welded to the car body roof. In this way, the secondary air ducts become structural parts of the car body roof, while using an easy and cost-efficient fixation process.
  • the main air duct is fixed to the car body roof.
  • the main air duct may thereby be placed on the car body roof and can directly be fixed on to the car body roof, which avoids the need for additional brackets for holding and supporting the main air duct.
  • This construction also allows for raising the interior ceiling of the vehicle and providing more space in the interior than known systems.
  • a method for mounting an air duct system with a main air duct and two secondary air ducts in a car body arrangement is described.
  • the car body arrangement may include a car body roof having an inner side and an outer side, wherein the car body roof separates an interior of the vehicle from an exterior of the vehicle.
  • the method includes providing the secondary air duct as a structural part of the car body roof; and fixing the main air duct on the car body roof. Thereby, the interior is in fluid connection with the main air duct through the secondary air duct.
  • the method further includes mounting an interior ceiling system to the inner side of the car body roof.
  • the interior ceiling system is mounted to the inner side by C-profiles.
  • the interior ceiling system allows for easy mounting of further components in the vehicle.
  • the C-profiles allow for mounting the interior ceiling system in a cost-efficient way.
  • Figures 1a to 1d show embodiments of a car body arrangement 100 for a vehicle, especially a rail vehicle.
  • a car body roof 130 separates an interior space 141 of the vehicle from an exterior surrounding 142 of the vehicle.
  • the car body arrangement 100 includes subdivided main air ducts 110 provided on the car body roof 130.

  • Each of the secondary air ducts 120 may have first openings 121 (only shown in Figure 1c by dashed lines), through which air is supplied from the respective part of the main air duct 110 to the secondary air ducts 120.
  • the secondary air ducts 120 also have second openings 122, through which the air in the secondary air ducts 120 is supplied to the interior space 141 of the vehicle. In this way, the secondary air ducts 120 may provide air channels between the two parts of the main air duct 110 and the interior 141 of the vehicle.
  • An arrow 123 in Figure 1c indicates an exemplary air flow from the main air duct 110 to the interior 141 of the vehicle.
  • the secondary air ducts include a plurality of first openings and/or a plurality of second openings along their longitudinal axis perpendicular to the cutting plane for allowing air to flow from the main air duct to the interior of the vehicle.
  • the secondary air ducts may omit a side wall (such as side wall 127), a top wall and/or a bottom wall for providing the respective fluid connection.
  • FIG. 1b an example of the bottom 128 of the secondary air duct 128 is shown.
  • the bottom 128 includes the second openings 122 through which the air in the secondary air ducts 120 is supplied to the interior space 141 of the vehicle (or the saloon of the vehicle).

  • the main air duct 110 may be covered, e.g. by one or more covers, in order to improve the aerodynamic characteristics of the main air duct. For instance, one cover may be provided at each of the right and left side of the main air duct.
  • the main air duct 110 may be fixed and sealed such as to provide a constant and reliable quality of the air supplied to the interior 141 of the vehicle.
  • the main air duct 110 may be fixed and sealed to the car body roof 130 and/or to the secondary air ducts 120.
  • the fixation of the main air duct 110 may be provided by a screw connection with a sealing or the like.
  • the secondary air ducts 120 can share a wall 113 with the main air duct 110.

  • the main air duct is attached to the car body roof so as to extend from the car body roof in a substantially perpendicular manner.
  • a part of the car body roof 133 extends between the secondary air ducts 120.
  • the secondary air ducts 120 can thus be described as being an integral part of the car body roof 130.
  • the secondary air ducts 120 are shown as protruding partially from the outer side 132 of the car body roof. However, it should be understood that the secondary air ducts may completely protrude from the car body roof, of which they are part of, or that the secondary air ducts may be arranged at least partially below the car body roof and protruding in the interior of the vehicle.
