Definitions

  • the invention relates to a heat exchanger, in particular for Rail vehicles, according to the preamble of claim 1.
  • Heat exchangers of this type are as cooling units in rail vehicles known and used for example for cooling the there with an electric drive combined converter and one Transformer. It is known that the power converter is preferably cooled with oil, while the transformers are usually water cooled are formed. Well-known two-circuit cooler blocks for this Both units are therefore in parallel sections the flat tubes of oil or water flows through, each cooled by air.
  • the known radiator blocks of this type are in a common Housing housed, with the supply and Ablite- or deflection boxes for the two liquid media connect to each other.
  • Heat exchangers of the type mentioned are in so-called Package construction manufactured, as for example for Heat exchanger according to DE 196 51 625 A1 is known. Also from DE 196 44 856 A1 is a manufactured in package construction finned tube block known for a heat exchanger in which one of all Recently, the intended for the flow of the coolant Flat tubes as adjacent channels of an extruded profile has produced. Even in this case, however, will occur leaks and in the formation of such finned tube blocks as two-circuit or multi-circuit cooling system the disadvantage occur that the different liquid cooling media can mix what should be avoided.
  • the object of the invention is to provide a heat exchanger of the above to create the type mentioned, the mixing of the two cooling circuit media or even more cooling circuit media with certainty prevented.
  • a heat exchanger of the above Art characterized by the fact that the serving as a leakage channel flow channel through two at a distance formed into each other in the flat tubes strips is formed.
  • the feed housing for the liquid Media on different length ranges of air flowed through channels be limited and in the region of the leakage channel be provided with openings in the environment.
  • openings can be used in the invention as through the housing width through slots between the Zuzhougepatusen be formed, each between the boundary edges the feed housing are arranged.
  • the heat exchanger from a in a housing 1 approximately in cuboid shape arranged radiator block 2 consists of the package construction is made.
  • the radiator block consists of mutually parallel Flat tubes 3, in the direction of arrows 4 and 5, respectively to be flowed through by a liquid medium and in the housing. 1 with their larger, serving as heat transfer surfaces side surfaces run parallel to the side walls 1a.
  • Between the flat tubes 3 are each perpendicular to the flow directions 4 or 5 running strips 6 inserted so that between adjacent flat tubes 3 flow channels 7 (see FIGS. 5 and 6), which flows in the direction of the arrows 8 of air become.
  • the flat tubes 3 is the front side in each case a collecting space 9 for Supply of a liquid medium 9 upstream, but only one Part of the inlet end faces of the flat tubes 3 covered and with a boundary wall 10 sealed in front of the end faces of the Flat tubes 3 ends.
  • the entry collection space 9 is a deflection space 11 assigned on the other side of the flat tubes 3, in which the through an inlet nozzle 12 and fed in the direction of the arrow 4 flowing liquid medium is deflected and the flat tubes 3 by a Exit nozzle 13 leaves, the one the Zuwoodsammelraum 9 sibling collecting space 9a is assigned. In known Way is to make this flow in the sense of Arrows 4 to reach, a partition 14 in the middle between the collecting boxes 9 and 9a arranged.
  • a this section 3b of the flat tubes associated deflection space 18 leads through the feed opening 16 in the direction of the arrows 5 fed liquid medium to the located next to the feed space 15 collecting space 15 a, from where the Medium can escape through the outlet nozzle 17 again.
  • the plenums 15 and 15a have boundary walls 19 on (Fig. 4), which is sealed at the end faces the flat tubes 3 ends.
  • oil for cooling a power converter introduced by the outlet pipe 13 cooled back is returned.
  • water for cooling of a transformer are fed into the heat exchanger, via the outlet nozzle 17 back to the transformer is returned.
  • a two-circuit radiator block is shown.
  • multi-circuit cooler system So then, if three different liquid cooling media flow through the flat tubes and through the perpendicular to it flowing air to be cooled, each between adjacent Cooling circuits run a flow channel in the sense of the flow channel 21 to be arranged as a leakage channel. Also in this case is an undesired mixing of the cooling circuit liquid locked out.
