Definitions

  • the invention relates to a rail vehicle with ventilation for electrical equipment.
  • the object is therefore to provide a rail vehicle with a simple vent for heat generating electrical equipment available.
  • a rail vehicle which comprises a heat-emitting electrical device. Furthermore, the rail vehicle comprises a first line within the rail vehicle, which is traversed by an air flow. Furthermore, the rail vehicle comprises a Venturi nozzle introduced in the first line, through which the air stream flows and comprises a taper, on which an inlet opening oriented in the direction of the electrical device is formed, and wherein the electrical device is positioned in fluid communication with the Venturi nozzle is.
  • the invention has the advantage that no additional fan is needed. This will installation space and maintenance saved up. Due to the air flow flowing through the Venturi nozzle, a static negative pressure is advantageously generated in the region of the taper. As a result, hot air or warm air can also be extracted from the heat-generating electrical device via the inlet opening of the Venturi nozzle. This in turn allows cooler air to flow to the electrical device and the electrical device is thus vented or cooled.
  • a heat generating electrical device may be, for example, a monitor, a switch, a display, a display element or a processor, but the invention is not limited to these examples.
  • a taper is a narrowing of the line cross-section. Flow connected means in other words in fluid communication standing.
  • the electrical equipment of the venturi nozzle is within a distance within which the generated negative pressure may produce an effective airflow from the electrical device to the venturi nozzle.
  • An electrical device is in other words an electrical component.
  • the first line is an air conditioning line which is connected to an air conditioning system located in the rail vehicle.
  • Typical rail vehicles have air conditioning.
  • a corresponding air conditioning with an air flow is thus already available and can be advantageously equipped with a Venturi nozzle.
  • no additional first line in the rail vehicle must be installed or installed.
  • the rail vehicle may comprise a second conduit, which is connected via the inlet opening with the Venturi nozzle and is guided from the inlet opening to an electrical device.
  • the suction point for sucking the heat or heat can be positioned very accurately on the electrical device. For example, at a certain point where heat or heat is generated locally, this heat or heat can be extracted. Also, for example, by the second line electrical equipment, which are positioned in inaccessible places, hot or warm air to be sucked. Furthermore, electrical devices further from the inlet opening can also be vented or cooled.
  • the second conduit comprises an open end, the open end being above the electrical appliance.
  • the open end being above the electrical appliance.
  • the rail vehicle may preferably comprise a plurality of electrical devices, wherein the second line is routed to the plurality of electrical devices. As a result, several electrical devices can be cooled or vented using the second line.
  • the second line may comprise a plurality of openings, wherein a respective opening in the second conduit is positioned on a respective electrical device.
  • the second conduit preferably has a diameter of less than 50 mm, more preferably less than 40 mm, particularly preferably less than 30 mm. As a result, the second line can thus be laid better through angled points of the rail vehicle.
  • the electrical device may also be positioned in an inaccessible location within the rail vehicle.
  • the invention thus has the advantage that by means of the second line also hidden built-in electrical devices can be vented or cooled.
  • the second line is preferably designed as a hose.
  • a hose is typically very flexible and thus, it is suitable to achieve concealed electrical devices and also to save space, without restricting further functionality.
  • the hose may be formed of a flexible material. Such a hose can be better laid in inaccessible places.
  • FIG. 1 a rail vehicle 1 is shown according to a first embodiment, wherein the rail vehicle 1 itself is indicated here only schematically.
  • the rail vehicle 1 comprises like the FIGS. 2 to 4 a ventilation system for an electrical device 10 or more electrical devices 10, 11, 12th
  • the rail vehicle 1 in this embodiment comprises a heat-emitting electrical device 10. Further, the rail vehicle 1 comprises a first line 20 within the rail vehicle 1, which is traversed by an air flow. Furthermore, the rail vehicle 1 comprises a Venturi nozzle 30, which is introduced in the first conduit 20. Thus, the air flow which flows through the first line 20 also flows through the Venturi nozzle 30.
  • the venturi 30 includes a taper 34 on which an inlet port 32 is formed. The inlet opening 32 is oriented in the direction of the electrical device 10.
  • the electrical device 10 is positioned in flow communication with the Venturi nozzle 30.
  • the electrical device 10 is positioned within a distance d from the Venturi nozzle 30.
  • the distance d is determined in such a way or the Venturi nozzle 30 and the electrical device 10 are spaced such that a flow connection between the inlet port 32 and the Venturi nozzle 30 and an electrical device 10 located within the distance d is generated.
  • a suction of hot air on the electrical device 10 can take place.
  • the electrical device 10 must therefore be positioned close enough to the Venturi nozzle 30 or in the vicinity of the Venturi nozzle 30. The suction of hot or warm air has the consequence that then cooler air can flow to the electrical device 10, which vents the electrical device 10 or cools.
  • the invention has the advantage that no additional fan is needed, which installation space and monitoring effort can be saved.
  • the Venturi nozzle 30 can be installed directly into the first conduit 20, without much installation space must be provided.
  • the inlet port 32 may preferably be positioned above the electrical device 10 to effectively extract heat or hot air from the electrical device 10.
  • Examples of an electrical device 10 are a monitor, a switch, a display, a display element or even a processor, the invention not being limited to these examples.
  • the first line 20 may preferably be an air conditioning line which is connected to an air conditioning system located in the rail vehicle 1.
  • An air conditioning line is also referred to as a climate hose or air conditioning duct.
  • Rail vehicles 1 typically have an air conditioning system, so that the air flow-through air conditioning line can act as the first line 20, without an additional installation of a further first line must be made in the rail vehicle.
  • FIG. 2 a rail vehicle 1 according to a second embodiment is shown.
  • the rail vehicle 1 comprises a second line 40.
  • the second line 40 is connected to the Venturi nozzle 30 via the inlet opening 32.
  • the second lead 40 is led to the electrical device 10.
  • heat or heat can thus advantageously be selectively extracted selectively at the electrical device 10.
  • the suction point is shifted by means of the second conduit 40 from the inlet port 32 to an open end 42 of the second conduit 40.
  • electrical devices 10 that are further away from the inlet opening 32 can also be vented or cooled by the second line 40.
  • the open end 42 is located in this embodiment above the electrical device 10, the invention is not limited thereto, which, for example, rising heat can be effectively sucked.
  • the open end 42 also on the side of the electrical device 10th be positioned where, for example, a region of local heat or heat is located.
  • the second conduit 40 may in preferred embodiments have a diameter D of less than 50 mm, more preferably less than 40 mm, and more preferably less than 30 mm.
  • the second line 40 is preferably formed comparatively thin.
  • the second line 40 can be more easily routed into existing environments and inaccessible locations.
  • the electrical device 10 may be installed in an inaccessible place or, in other words, hidden. Such hidden built-in electrical devices 10 can thus be vented or cooled by means of the second conduit 40.
  • the second line 40 is formed as a hose which is flexible and thus easy to install, wherein the hose is advantageously made of a flexible material.
  • FIG. 3 a rail vehicle 1 according to a third embodiment is described.
