Definitions

  • the invention relates to a cooling air supply arrangement for a rail vehicle according to the preamble of claim 1.
  • a cooling air supply arrangement for a rail vehicle with at least one radiator for tempering a heat-generating component of the rail vehicle, such as an electric or diesel-powered drive unit, with a Abscheidegitter to Inlet of fresh air and a fan for sucking the fresh air through the Abscheidegitter therethrough in the direction of the radiator is, for example, from DE-OS-25 18 651 known.
  • the separation grid is electrically heated, accumulated snow can be thawed intermetierend during vehicle standstill.
  • continuous operation of electric grid heating is associated with low to medium to high air mass flows Outdoor temperatures such as in winter energetically not useful, since in about the same electric heating power to defrost the grid may be required as heat must be dissipated by the mounted behind the Abscheidegitter cooler.
  • the invention has the object, the aforementioned cooling air supply arrangement in
  • At least one thermal bridge is provided between a heat-emitting surface of the radiator and the Abscheidegitter.
  • a plurality of thermal bridges can be provided, which are distributed substantially uniformly between the Abscheidegitter and the heat-emitting surface of the radiator.
  • the affected radiator may be associated with any electrical or other component of the rail vehicle to be cooled.
  • Examples of such components are: traction converters, auxiliary converters, traction motors (electric, fluid cooled), transformers, battery chargers, internal combustion engines, generators and gearboxes / retarders.
  • the at least one thermal bridge is designed as a plate, which then extends from the heat-emitting surface of the cooler to a region of the Abscheidegitters.
  • various variants are conceivable, for example, a centrifugal sediment separator with round cross section.
  • the thermal bridge plate may then be provided with bores for receiving a respective element of a centrifugal sediment separator, wherein the elements may be thermally conductively connected to the at least one thermal bridge.
  • the elements of the Abscheidegitters eg centrifugal sediment
  • the elements of the Abscheidegitters are arranged in the flow direction of the cooling air immediately in front of the radiator.
  • the elements of the Abscheidegitters are preferably arranged vertically, the heat bridge plate is horizontal in this case. This has the advantage that sediment can be removed by the action of gravity down from the cooling arrangement out.
  • the separation grid 1 In view of its external position, the separation grid 1 is exposed to external environmental influences in winter conditions. This means that the separation grid 1 can be added with snow or iced.
  • the cooler 2 comprises a cooling medium line 4, in which heated cooling medium is located. Amount of heat discharged from the cooling medium is transmitted to an outer surface of the radiator 2, which typically has an in FIG. 2 has better recognizable rib structure.
  • the heat-emitting outer surface of the radiator 2 and possibly the cooling medium line 4 are connected via thermal bridge plates 5 with the Abscheidegitter 1, wherein the thermal bridge plates 5 substantially evenly vertically above each other between the Abscheidgitter 1 and the radiator 2 are arranged.
  • About the thermal bridge plates 5 is originally derived from the cooling medium heat, which is transmitted via the outer surface of the radiator 2 on the thermal bridge plates 5, registered in the Abscheidegitter 1, so that here an increase in temperature can be completed.
  • FIG. 2 shows that each of the thermal bridge plates 5 is equipped with a number of holes 6, each serving to receive an element of a centrifugal sediment separator.
  • the elements 7 of the centrifugal sediment separator are inserted into the bores 6 and connected in a heat-conducting manner to the thermal bridge plate 5.
  • the thermally conductive connection can be realized in various ways and combinations thereof, eg clamping the centrifugal force sediment separator elements 7 in the crimped bore 6 of the thermal bridge plate 5 or cohesive connection (soldering, welding) in the thermal bridge plate. 5
  • the deposition grid elements 7 e.g., centrifugal force separator elements
  • the separation grids 1 are frosted, the heat is dissipated via the heat bridge plates 5 from the cooler 2 to the separating grate 1 added with ice or snow. In this way, on the one hand the heat dissipation from the radiator 2 is secured and on the other hand the separation grate 1 (partially) de-iced.
