Definitions

  • the invention relates to a cooling device in a fuel cell vehicle according to the preamble of claim 1.
  • Such vehicles usually include a polymer electrolyte fuel cell (PEM fuel cell) in which an anode and a cathode are disposed on both sides of a proton conducting polymer electrolyte membrane.
  • PEM fuel cell polymer electrolyte fuel cell
  • the fuel cell reaction generates heat which must be dissipated.
  • the temperature of the polymer electrolyte membrane has to be controlled to a fixed, relatively low temperature in order for the fuel cell to generate electric power with the highest possible safety and high efficiency.
  • a typical PEM fuel cell is constructed so that a flow path for cooling water inside the fuel cell is formed so that the cooling water can circulate through the flow path and dissipates the heat generated in the generation of electric power. Because of the relatively low temperature differences to the environment, the heat dissipation is problematic, especially at high outdoor temperatures or at full load.
  • the vehicle cooling is usually carried out via a main radiator, which is located in the front region of the fuel cell vehicle.
  • the disadvantage here is that the space in the front part of the vehicle is already heavily limited anyway, so that a larger radiator with high dissipated heat output or an additional radiator is difficult to integrate.
  • the published patent application DE 199 60 166 A1 discloses a cooling device which has a radiator block arranged on the roof side with a cooling fluid channel arrangement and a cooling air channel arrangement in thermal contact with it, which can be flowed on by the wind. This will solve the space problem. Also, the cooling effect of the airstream no additional on-board energy is needed, which is anyway only limited available for cooling purposes. However, additional space is needed on the roof. There, however, the sunlight is particularly strong and unfavorable to the radiator.

  • the flexible piping can be easily adapted to the bodywork.
  • the additional cooling surfaces are hidden in the body, so that the air resistance or. the cw value of the vehicle is practically unaffected.
  • the additional Cooling surfaces can be guided, for example in their design as flexible piping through existing cavities of the fuel cell vehicle.
  • the length of the pipes can be adjusted to the amount of heat to be dissipated, with the principle that with longer pipes due to the larger surface more heat can be dissipated than shorter.
  • the additional cooling surfaces can be arranged in an underbody area of the vehicle. An arrangement in a roof area of the vehicle and / or in a side area, for example in the door sill, is also possible.
  • the additional cooling surfaces can also be arranged in at least one wheel arch.
  • the additional cooling surfaces in the vehicle are arranged so that they can be cooled by means of airstream.
  • an arrangement of the additional cooling surfaces can be provided, in which a favorable cooling air flow behavior can be realized.
  • cooling fins may be provided which are so exposed that they can be coated by the wind and thus provide additional heat dissipation.
  • additional cooling surfaces may be provided, which are arranged in different areas of the vehicle.
  • the additional cooling surfaces designed as pipelines can not be elongated, but instead can be wave-shaped in the longitudinal direction.
  • the wave troughs and the wave crests can be aligned parallel to the vehicle longitudinal axis in order to achieve a favorable cooling air outflow behavior of the additional cooling surfaces.
  • the additional cooling surfaces can be laid spirally. This ensures a particularly favorable heat dissipation. This can be a re- latively large surface can be created for heat dissipation in a small space.
  • a flow connection between a cooling medium of the main cooler and the additional cooling surface or the additional cooling surfaces can be produced, wherein cooling water is preferably provided as the cooling medium.
  • One or more valves may be provided to connect or disconnect the additional cooling surfaces fluidly to the main radiator.
  • a bypass valve can be provided for this purpose.
  • the cooling circuit or. its heat-dissipating surface can be changed in a simple manner by the additional cooling surfaces are connected via the bypass valve to the main radiator or separated again as cooling demand decreases. It is advantageous that the thermal mass of the cooling circuit during a cold start or. Freeze starts is kept low. Thus, conveniently, the operating temperature can be reached quickly.
