Definitions
- the invention relates to a device according to the Preamble of claim 1 and a Rail locomotive with such a device.
- the known locomotive contains four fans for Ventilate four in pairs in two bogies arranged traction motors and two fans for Ventilation of oil coolers for those arranged in the vehicle body Auxiliary units, in particular converter systems and one Transformer.
- the fans are each in the vehicle body above the traction motor or the oil cooler between a suction side and a pressure side section an air duct arranged.
- the fans are each in one at the bottom of the Supported vehicle body, from bottom to top flowable air duct arranged, the Converter and converter units below the Fan in a suction section of the Air duct are attached.
- the cooling air is extracted from the Engine room through below the vehicle floor arranged oil cooler and by the converter and Power converter units are sucked in and in the roof area of the Vehicle carried outside (Glasers Annalen, volume 111 No. 4, April 1987, Berlin, pages 107-114).
- Diesel engines located below the vehicle floor and auxiliary units arranged in the roof area are the Diesel engines each via a vertical air intake line with an air cooler arranged in the roof area connected and each to a leading against the roof area, exhaust pipe provided with a silencer connected.
- the air intake and exhaust pipes are in two the floor, the passenger compartment and the roof area of the railcar vertically penetrating channels arranged, which are each double-walled, whereby the space between the double walls with a filled with heat-insulating and soundproofing material is to reduce the heat and noise pollution of the passenger compartment to minimize.
- the invention has for its object a further developed especially in this regard To provide ventilation device which essentially within the by the design of the locomotive given dimensions of the installation space - if necessary as a replacement for an existing one Ventilation device - built into the vehicle body can be and which with little construction effort, especially without significant changes in the environment of the Installation space of the device, a reduction in Noise emissions guaranteed.
- this object is achieved by that the air duct is at least part of its length with a liner facing the air flow is provided with a sound absorbing material.
- the inventive design of the device allows a targeted reduction of the radiated Noise, in particular the airborne noise emitted by the Fan and the "flow noise" within the Air duct.
- the inventive Device also allows a simple Retrofitting an existing vehicle. Given External dimensions of the air duct can be determined by the lining according to the invention, although the flowable Cross section reduced and thus the Flow rate of the cooling air increased accordingly will; however, this apparent disadvantage is caused by the achievable sound-absorbing effect of the lining both in the direction of flow and against Flow direction of the cooling air more than weighed.
- a undesirable reduction in the cross-section that can be flowed through to avoid the canal section in question without Liner executed and this in one for it better appropriate section can be arranged.
- An essential part of the counter flow direction the noise emitted by the cooling air can, according to claim 2 be reduced in that at least part of the Lining in a suction section of the air duct is arranged.
- the embodiment according to claim 3 enables an effective Reduction of one that arises especially in the intake area Noise share, which over the in the roof area arranged suction port is emitted and which therefore in a different way, such as those provided by the railway Noise barriers, as a rule, cannot be reduced.
- the hood part provided in the roof cavity can be in one any, for optimal absorption of airborne sound favorable form, especially with a flowable Cross section that is larger than that limited by the space in the vehicle body Cross section of the below the roof cavity itself continuing part of the air duct.
- the hood part can also with a length effective for sound absorption be carried out according to the size of the flowable cross section can be optimized.
- At least one parallel to the direction of flow running guide element is the hood part divided like a backdrop, so that for absorption effective surface corresponding to the airborne sound enlarged and thus a correspondingly improved Noise reduction can be achieved.
- the lining designed according to claim 5 stands out in particular from the fact that as an absorption material foam used at low frequencies, e.g. in a range of approximately 200 Hz, a relatively high one Airborne sound absorption effect ensured, in which mentioned area e.g. an absorption degree ⁇ greater than 0.3 can be achieved.
- the foam material used is also fire retardant and moisture resistant as well especially insensitive to abrasion, so that at low maintenance and high operational reliability Lining ensures and especially a burden the environment by abrasion of the lining can.
- the embodiment according to claim 8 enables simple Way an increase in airborne sound absorption effective surface of the lining and thus a corresponding improvement in sound absorption within of the air duct through which it flows.
- the embodiment according to claim 9 is particularly for Arrangement in the outlet area of the pressure side section suitable for the air duct, with this also in Flow direction of the cooling air last duct section one effective sound absorption can be achieved.
