Definitions

  • the present invention relates to a heat dissipation device for a rail vehicle and a rail vehicle.
  • Rail vehicles have a large number of electronic components that are housed in cabinets or containers and entail a certain amount of power loss and radiate heat. In order to ensure reliable operation of such components, it is usually necessary to provide cooling and to dissipate the heat radiated by the electronic components. As a rule, fire protection regulations and, if necessary, filter systems for the cooling air must also be taken into account in order to provide safe heat dissipation.
  • an energy supply device for a passenger carriage which is arranged in a closed space and is connected to a heat exchanger.
  • the heat exchanger is located directly below the energy supply block and consists of a large number of rectangular tube cross-sections lying side by side, through which air from the room and air from outside flows alternately.
  • a device for dissipating heat for a rail vehicle includes a car body with a space-defining wall that includes a plurality of separate air ducts, with a first air duct having an inlet opening and a second air duct having an outlet opening, and the first air duct having the inlet opening and the second Air duct with the outlet opening are fluidly coupled to each other.
  • the device also has an electronics container, which is designed to accommodate electronic components for the rail vehicle and is coupled to the wall.
  • the electronics enclosure has an exit port and an entry port, with the exit port being fluidically coupled to the entry port of the wall and the entry port being fluidically coupled to the exit port of the wall.
  • the electronics container, the air duct with the inlet opening and the air duct with the outlet opening form a closed flow circuit.
  • the device further comprises a fan unit which is coupled to the electronics container and/or to the wall. The fan unit is set up to form an air flow in the flow circuit.
  • the device uses elongated cavities and the air volumes therein to enable efficient heat dissipation. It is particularly suitable for use in a rail vehicle, which generally has a plurality of car bodies with extruded profiles that have such unused cavities. Efficient cooling of electronic components of a rail vehicle can be realized by means of the device described. This can contribute to safe and cost-effective operation of the rail vehicle.
  • an electronics container for example a cabinet or a container
  • cabinets and containers are used to protect the electronic components from external influences, for example with regard to moisture or electromagnetic compatibility.
  • Such a cabinet or container is installed, for example, in the rail vehicle, on a roof or in an underfloor.
  • the electronic components also include electrical and electromechanical components, which generally require sufficient cooling or heat dissipation in order to be able to ensure proper functioning in each case.
  • Electronics located in cabinets or containers can be cooled by convection, for example, with a total power loss of up to approximately 500 W.
  • the radiated thermal energy can still be given off sufficiently well via free convection on the outside of the cabinet or container.
  • the risk of hotspots or local hot spots forming is relatively high. Such can lead to limitations in service life and, under certain circumstances, also result in an emergency shutdown of the electronic components.
  • Cooling using a mass flow enables heat to be dissipated from electronics cabinets or containers with power loss densities of around 500 W - 1300 W.
  • air intake from the passenger compartment, the driver's cab or the environment is required, which carries the risk of carrying impurities. Additional filter systems and their maintenance are required and lead to a more complex structure and higher costs.
  • the air used for cooling must not be blown out into the passenger compartment, for example, so that concepts for further extraction must be provided. Fire protection requirements cannot be met without special constructions, for example to close existing openings safely and reliably in the event of a fire.
  • increased noise pollution for passengers and drivers of a rail vehicle is given by air openings.
  • Cooling using a separate heat exchanger enables heat to be dissipated in power loss-tight electronics cabinets and containers with outputs of around 1000 W.
  • the internal air does not come into contact with the environment, but an external part of the heat exchanger leads to contamination, so that there is an increased need for maintenance.
  • additional space is required for the heat exchanger.
  • Efficient, cost-effective and environmentally friendly heat dissipation is made possible by means of the device described. It uses a car body and the separate cavities in it that serve as heat exchangers. In this way, a simple, safe and reliable heat dissipation can be realized and a contribution can be made to increasing the service life of the electronic components arranged in the electronics container.
  • the electronics container of the device forms, for example in the form of a cupboard or a container, a structure encapsulated from the environment for electronic components to be arranged therein, so that, for example, no or only relatively little effort is required with regard to fire protection specifications.
  • An expanded encapsulated structure can be implemented by means of the device, so that the self-contained flow circuit and the air flow that can be generated therein are separated from the environment. Therefore, any smoke development that may occur due to electronic damage is also limited to this closed flow circuit and is separated, for example, from an interior of a carriage of a rail vehicle. Requirements based on fire protection regulations are therefore low, so that is further contributed to a particularly cost-effective heat dissipation.
  • a car body as a heat exchanger provides a relatively large area for heat dissipation, especially since a conventional car body in an integral design made of aluminum has a large number of unused cavities that can be used specifically for a heat-dissipating air flow using the device described.
  • a car body has, for example in the floor area, an elongate extruded profile which has large cavities and corresponding air volumes. These cavities form a respective air duct, which is fluidically decoupled from one another by stabilizing partition walls.
  • the air ducts are used and preferably fluidically connected to one another in a large number in a targeted manner in order to form a long, continuous air duct and enable efficient heat dissipation. Measures for filtering the air or with regard to fire protection regulations are not required.
  • the first air duct with the inlet opening and the second air duct with the outlet opening realize one and the same air duct within the wall.
  • Such a configuration with an elongated air duct, which has the inlet opening at one end and the outlet opening at the other end, is suitable, for example, for a correspondingly designed and arranged electronics container, which is for example in the form of a narrow cabinet above the air duct in a Interior of the car body is arranged.
  • the air duct with the inlet opening and the air duct with the outlet opening each form a separate air duct within the wall.
  • the separate air ducts can be formed directly adjacent to one another and separated from one another by means of a wall, with the separating wall having an opening which forms the fluidic coupling between the adjacent air ducts.
  • the separate air ducts can be formed at a distance from one another and can be coupled to one another by means of a fluid power bridge.
  • the device includes a bridge element that forms the fluidic coupling between the air duct with the inlet opening and the air duct with the outlet opening.
  • a bridge element can be implemented, for example, as a pipe connection or as a hose, which forms a bridge channel and connects the air channels to one another in terms of fluid technology.
  • the air ducts each have a corresponding coupling opening, which can also be referred to as an inlet opening or outlet opening in relation to an operationally provided air flow.
  • the device comprises a plurality of air ducts with a respective inlet opening and a respective outlet opening, which are fluidically coupled to one another, and a plurality of bridge elements, of which a bridge element is a respective fluidic coupling between two air ducts of the plurality of air ducts trains.
  • the electronics box has an opening in the bottom at one end that is fluidically coupled to the inlet opening of a first air duct for exit from the electronics box.
  • the first air duct has an outlet opening which is as far away as possible from the inlet opening and which is fluidically connected to an inlet opening of a second air duct.
  • the second air duct correspondingly has an outlet opening which is fluidly coupled to an inlet opening of the electronics container, which for example is formed at another end in the bottom of the electronics container.
  • a self-contained flow circuit is thus formed within the electronics container and the car body.
  • Air is preferably sucked in from the electronics cabinet in an upper area in relation to an operational arrangement of the electronics container on or in the car body.
  • a bridge duct can ensure that the air drawn in can flow back to the cabinet or electronics container.
  • the functionality of the device described can also be implemented for underfloor components or on a roof of the car body.
  • An implementation is also possible for end wall cabinets, since the end walls of a conventional car body usually also have drawn hollow profiles made of aluminum, which allow useful heat dissipation with the air volumes located therein.
  • an energy input through solar radiation may have to be taken into account.
  • the device could have a shading element to ensure appropriate shading.
  • the wall comprises an extruded profile element which has the plurality of separate air ducts and which forms at least part of a floor, an end wall, a roof or a side wall of the car body.
  • the device comprises a further fan unit which is coupled to the electronics container and/or to the wall and which is set up to generate an air flow in the flow circuit.
  • a respective fan unit can be used to force air circulation and contribute to efficient heat dissipation.
  • a particularly reliable and stable air flow within the closed circuit made up of the electronics container and the wall of the car body can be formed by means of two or more fan units. In addition, a contribution can be made to lower noise emissions.
  • One fan unit is arranged, for example, in the first coupling interface between the electronics container and the wall which forms the fluidic outlet from the electronics container, and the other fan unit is arranged in the second coupling interface which forms the fluidic input back into the electronics container.
  • a fan unit or an additional fan unit can be arranged within the bridge element, if one is provided.
  • a fan unit within such a bridging channel may be more easily accessible and allow for easy maintenance or replacement of the fan unit.
  • a tolerable, installed power loss in an encapsulated electronics cabinet or container can be significantly increased by means of the device described.
  • an additional power loss of 50 W/m can be dissipated in a simple loop with two air ducts, each a few meters long.
  • the possible heat dissipation is thus significantly improved and the electronic components also remain encapsulated in the electronics container, so that no contamination occurs from outside or to the outside in operational states.
  • the heat dissipation principle that can be implemented using the device can be implemented on the roof, in an underfloor, on the side walls or the end walls of the car body, provided that the respective space-limiting wall has appropriate cavities, such as those of an extruded hollow profile.
  • the device enables simple, time-saving and cost-effective maintenance and reduced noise emissions.
  • the device can thus be retrofitted into existing vehicle systems in a simple manner and can be retrofitted into vehicles with an integral design with little manufacturing effort.
  • a rail vehicle comprises an embodiment of the heat dissipation device described above, which is coupled to a car body of the rail vehicle.
  • the device can comprise a space in a wagon floor, an underfloor, a side wall, a front wall and/or on a roof of the wagon body and, with this available space, enable useful and cost-effective heat dissipation.
