Description
Technical Field
The present invention relates to an undersea equipment rack for a rail vehicle.
Background
Undersea equipment carriers, also known as undersea containers, are used very frequently in rail vehicles and are used for mounting electrical devices, preferably devices with high energy requirements. They offer the advantage that these electrical devices can be constructed and tested separately from the car of the rail vehicle and installed underneath the car when the vehicle is finally installed. Depending on the type of electrical device arranged in the underfloor vessel, a specific electrical loss power is generated, which is typically discharged by means of a forced-ventilated air cooling system. In this case, ambient air is sucked in at one point of the underfloor installation support via the air filter, guided in the interior of the installation support via the heat-dissipating surface and discharged again to the environment at another point. Depending on the device to be cooled, the discharged air can each have a different temperature. One extreme case is an undersea device with a brake resistor, which may reach 700 c and create an extremely hot exhaust flow. If this is not a problem even when driving on free road sections, this exhaust gas must lead to problems in the stop, in particular in the tunnel. Exhaust air entering through the platform gap in the door region can be uncomfortable for the passengers and can lead to injury in extreme cases. The hot exhaust air entering the waiting space must also be cooled again by air conditioning equipment if necessary. Stopping the ventilation of the equipment to be cooled during the stay in the station is an unacceptable option, since the brake resistor has, for example, the highest cooling demand at this point in time.
Disclosure of Invention
The object of the present invention is therefore to specify an underfloor installation support for a rail vehicle, which avoids the disadvantages of the prior art and in this case provides a maximum defined cooling power or cooling air flow at each operating point in time.
This object is achieved by an undersea device carrier for a rail vehicle with the features of claim 1. Advantageous embodiments are the subject matter of the dependent claims.
According to the basic idea of the invention, an underfloor installation support for a rail vehicle is provided, comprising a forced air system with at least one air suction point and at least one air outlet, wherein an air guide is provided, which can be switched between at least two positions, wherein in a first position of the air guide the air flows out in a first outflow direction and in a second position of the air guide the air flows out in a second outflow direction.
The advantage achieved thereby is that the exhaust gas can be discharged in a specific direction, so that the exhaust gas can be deflected in a direction which is advantageous at the respective point in time.
According to the invention, the underfloor installation support is equipped with an air cooling system, in which ambient air can be sucked in via at least one blower suction point and the cooling air is blown out either in the first outflow direction or in the second outflow direction. For this purpose, an air guide is provided which causes a corresponding diversion of the air flow. This air guiding means may for example comprise dampers, which are controlled such that they are worth releasing or closing a specific path for the cooling air.
The outflow directions are advantageously oriented such that they blow off the exhaust gases in opposite directions. In the installed position of the device carrier, it is thus possible for the exhaust gas to flow out transversely to the longitudinal direction of the rail vehicle, wherein, when parked, the exhaust gas is blown out only in the opposite direction to the platform. This prevents hot air coming out of the platform gap from damaging passenger comfort, which is important in particular in tunnels.
Cooling air is typically pumped either on both sides (with respect to the longitudinal sides of the rail vehicle) or underneath from the direction of the track bed. In the first case, the exhaust gas is blown out downwards, in the second case, to both sides.
Both exemplary embodiments of the known undersea device carrier each have a particularly advantageous form of air guidance (Auspr ä gun). If the blower suction point is arranged on the underside of the underfloor installation support and thus blows through two outlets arranged laterally in each case, it is recommended to provide a damper which alternatively closes off one of the outlets and thus discharges the cooling air flow only through one of the outlets. When the vehicle is parked on a platform, the platform-side air doors are closed in each case, while driving on the free road section, both air doors are opened and the exhaust air is thus discharged via the two outlets.
In the case of a underframe system with a lateral supply air suction point and a downward-directed outlet, it is recommended that the outgoing air is associated with a transverse component of speed, i.e. that the outgoing air can flow out in a directed manner onto one side (of the rail vehicle). For this purpose, an air guide plate can be provided, for example, which is arranged pivotably in the air flow and thus allows the air flow to be discharged in a directional manner.
Another embodiment provides that the outlet is configured such that it has two outlet channels, which each conduct the exhaust gas in one direction and each close one type of outlet channel depending on the desired outlet direction.
In a further embodiment of the invention, it is advantageous if the air guide is adjusted during driving to a position in which a minimum flow resistance for the cooling air and thus a maximum cooling effect is achieved.
The air guide is preferably controlled automatically and by means of an electrical drive. For this purpose, for example, a control device is provided, which receives information from a vehicle-side device (for example a door control device or a vehicle control device) about the exit side to be selected, which is necessary in the currently used docking station. This control mechanism comprises the power electronics required to drive the air guiding device and optionally also means for detecting the operational status of the relevant driver and for detecting faults in these components. It is particularly advantageous if a bidirectional data interface is provided, via which commands are transmitted from the vehicle-side device to the control device and status or fault notifications are transmitted to the vehicle-side device.
A particularly advantageous embodiment of the invention provides that the air guide device can be actuated directly mechanically by the door drive or the drive of the gap bridging structure. Since in most cases only the vehicle-side door is opened in the docking station, the door drive or gap-bridging structure drive also drives the air guide of the underframe equipment rack simultaneously with the door or gap-bridging structure. It is particularly advantageous to use a drive of the gap bridging structure here, since this drive acts before the door is opened and after the door is closed, so that the air guide is in any case adjusted into the correct positions before the door is opened. The drive force can be transmitted to the air guide device, for example, by means of a bowden cable.
Other forms of variable cooling air blowout of the underfloor equipment rack can also be achieved, but with reduced efficiency and higher manufacturing costs. For example, an individual fan and an associated air path to the respective exhaust gas outlet can be provided for each blowing direction, which, although a variable air guide is not required, increases the production effort.
Another possibility provides that the cooling air ventilator is designed to be reversible, so that the blower suction area and the exhaust air outlet can be interchanged at will with respect to their function. This is disadvantageous, however, because conventional ventilators are only efficient in the direction of air transport, and are mostly very inefficient in the opposite direction. This can only be solved by using expensive ventilators with blade adjustment.

Detailed Description
Fig. 1 shows schematically and schematically an underfloor equipment rack with a downward blowing. A conventional undersea equipment rack 1 is shown, which is arranged on the underside of a rail vehicle 2, which is in a stop in a tunnel. The underfloor installation bracket 1 has two laterally arranged blower suction points 3, through which the blower 1 is sucked into the interior of the underfloor installation bracket 1. The exhaust gas 6 which is then heated is blown out on the underside of the underfloor installation support 1 via the exhaust gas outlet 4 and distributed under the rail vehicle 2, wherein a part of the exhaust gas 6 flows into the gap between the rail vehicle 2 and the tunnel wall and another part of the exhaust gas 6 flows in the platform direction via the platform gap 8.
Fig. 2 shows an example and schematic illustration of an undersea device carrier according to the invention with downward blowing on the left-hand platform. A situation is shown which corresponds to that in fig. 1, wherein, however, the underfloor installation support 1 according to the invention is arranged here below the rail vehicle 2. The underframe equipment carrier also comprises two laterally arranged blower suction areas 3, as in the prior art underframe equipment carrier. The exhaust air 6 is discharged via an exhaust air outlet 4 on the underside of the underfloor installation bracket 1, wherein an air guide 5 is provided, by means of which the discharge direction of the exhaust air 6 can be predetermined. The air guiding means 5 may be realized in the form of a plurality of air guiding plates, which may each occupy at least two positions with respect to the air flow and may thus guide the air flow in a specific direction. In the embodiment shown, the air guiding plates of the air guiding device 5 can be adjusted such that the exhaust air 6 flows in the direction of the tunnel wall, i.e. counter to the platform, and thus virtually no part of the exhaust air 6 is discharged through the platform gap in the direction of the platform. For moving the air guide plate of the air guide 5, a drive, for example an electric motor, a stepper motor or an electromagnet, is provided. Such a driver is not shown in order to simplify the schematic.
Fig. 3 shows an example and schematic illustration of an undersea device carrier according to the invention with downward blowing on the right-hand platform. An embodiment of the underfloor installation bracket 1 of fig. 2 is shown, in which the rail vehicle 2 is parked on a docking station with a docking station on the right vehicle side. The air guide plate of the air guide 5 is adjusted in such a way that the exhaust air 6 blows out to the left of the longitudinal axis of the vehicle and therefore does not exit through the platform gap 8.
The blowing direction is irrelevant when the rail vehicle is traveling, and thus the air guiding plate of the air guiding device 5 can be brought to the position required for the next stop or kept in the final position until the next stop during traveling. If three possible positions of the air guide plate of the air guide 5 are provided, the air guide plate of the air guide 5 can be brought into a neutral intermediate position. This can be particularly advantageous when in this neutral intermediate position a minimum flow resistance of the air guide 5 occurs and thus the exhaust gas 6 reaches as large a volume flow as possible during travel.
Fig. 4 shows schematically and schematically an undersea equipment rack with side air blowing. A conventional undersea equipment rack 1 is shown, which is arranged on the underside of a rail vehicle 2, which is in a stop in a tunnel. The underfloor equipment carrier 1 has a blow-in suction portion 3 arranged below, through which a blow-in 7 is sucked into the interior of the underfloor equipment carrier 1. The heated exhaust gas 6 is then blown out through the two exhaust gas outlets 4 on the side of the underfloor equipment carrier 1. Here, a part of the exhaust gas 6 flows into the gap between the rail vehicle 2 and the tunnel wall, but another part of the exhaust gas 6 is blown out in the direction of the platform directly below the platform gap 8, which is particularly disadvantageous.
Fig. 5 shows an example and schematic illustration of an undersea device carrier according to the invention with lateral blowing on the left-hand platform. A situation is shown which corresponds to that shown in fig. 4, but in which the undersea device carrier 1 according to the invention is arranged below the rail vehicle 2. This underframe equipment carrier comprises two laterally arranged exhaust outlets 4 as in the underframe equipment carrier according to the prior art. An air guide 5 is provided, which comprises two air doors, one associated with each outlet 4 and thus arranged in such a way that the air doors can close the respective exhaust gas outlet 4. The dampers of the air guiding device 5 are preferably force-supportably adjustable independently of each other between an open position and a closed position. The discharge direction of the exhaust gases 6 can thus be predetermined, so that, as in the illustrated embodiment, the station-side exhaust gas outlet 4 can be closed and all the exhaust gases 6 can exit through the tunnel-side exhaust gas outlet 4. For moving the damper of the air guiding device 5, a drive is provided, for example an electric motor, a stepper motor or an electromagnet. Such a driver is not shown in order to simplify the schematic.
Fig. 6 shows an example and schematic illustration of an undersea device carrier according to the invention with lateral blowing on the right-hand platform. The embodiment of fig. 5 is shown, wherein the damper of the air guiding device 5 on the right side of the vehicle is closed during parking on the right side platform, whereby the exhaust air 6 is blown out on the exhaust air outlet 4 on the tunnel side. During driving, it is recommended to open all the dampers of the air guide 5, since the best cooling effect on the components of the underfloor installation rack 1 that are to be cooled is thereby achieved.
Fig. 7 shows an electrical block diagram of an example undersea device carrier 1 according to the invention, in a schematic way. The underfloor equipment carrier 1 comprises a control device 9, which is provided for operating an electrical drive 12. The drive 12 acts on the air guide 5, which can thus adjust its means for controlling the air flow (damper or air guide plate) into the desired positions. It is provided that the air guiding device 5 is functionally monitored, and during functional monitoring, a position feedback signal 13 is transmitted from the air guiding device 5 to the control device 9. Thereby, a malfunction of the drive 12 or of the air guide 5 can be detected. The control device 9 is connected to the vehicle-side control device 10 by means of a data interface, so that data 11 can be transmitted in both directions between the control device 9 and the vehicle-side control device 10. Through this data interface, commands can be transmitted to the control device 9 and feedback can be transmitted to the vehicle-side control device 10.
Fig. 8 shows an example and schematic illustration of an undersea equipment rack with mechanically driven air guides. A cross section of an undersea equipment rack 1 is shown, which is arranged on the underside of a rail vehicle 2. The rail vehicle 2 is equipped with a gap bridging structure in the form of a sliding pedal 14 which can be actuated by means of a sliding pedal drive 15. The underfloor installation bracket 1 is constructed according to the principle shown in fig. 5 and 6, according to which one of the two exhaust outlets 4 can alternatively be closed. The air guiding device 5 is thus equipped with a damper. The sliding pedal drive 15 acts on the movably mounted pedal and, via the force transmission mechanism 16, also on the air guide 5 and thus moves the damper. This force transmission means 16 can be designed, for example, as a bowden cable, as a hydraulic force transmission means, but alternatively also as a link drive. In fig. 8, only one half of the underfloor installation support 1 is shown, the other half being formed mirror-symmetrically to the first half. A further preferred embodiment of the underfloor installation support 1 with an air guide plate arranged in the exhaust gas flow can likewise be used in the principle illustrated.
