Definitions

  • the invention relates to a cooling device for in particular liquid-cooled internal combustion engines for commercial vehicles and. Like., With an air tube cooler arranged in front of the front side of the internal combustion engine, one or more motor-driven fans and a cooling air duct between the cooler and fan or fans.
  • the cooling tubes of the air tube cooler are smooth tubes and lie horizontally.
  • a long tube length would be desirable for high cooling capacities;
  • relatively short pipes 150 to 200 mm were chosen in the known trachea coolers, and the number of cooling pipes was used to achieve a sufficient cooling capacity simultaneously reduced tube cross section increased. But that was the production of the cooler more difficult and wage-intensive.
  • the requirements for joint technology increase due to the larger number of joints.
  • both the air tube cooler and the fan (s) are generally located on the front side of the internal combustion engine, there are high pressure losses as a result of the inflow and cross-flow around the engine block through the air leaving the fan (s).
  • heat exchangers of the “air tube type” are also known, in which the air flows through vertical tubes, turbulence generators being arranged in the tubes to increase the heat transfer on the air side.
  • turbulence generators being arranged in the tubes to increase the heat transfer on the air side.
  • the invention has for its object to provide a cooling device of the type mentioned, which, given a given cooling capacity and flow area, enables both longer individual pipe lengths and less fan (s) power.
  • the trachea cooler is arranged with vertically or almost vertically extending tubes equipped with turbulence generators, the individual length of the tubes being between approximately 30xd and 70xd, where d is the equivalent diameter in mm that the or Fans are arranged at a point at which the air leaving the fan or fans can flow into the open as freely as possible, and that an inflow elbow is provided for supplying the cooling air to the cooler.
  • a so-called trachea cooler 1 is arranged on the front side in front of the engine block 2 - the engine shaft of which coincides with the longitudinal axis of the vehicle - in such a way that the tubes 3 through which the cooling air flows are perpendicular.
  • the length of the individual tubes, which are equipped with turbulence generators, in particular in the form of circumferential beads provided at certain intervals, is approximately between 30xd and 70xd, where d is the equivalent diameter in mm. (With an inner pipe diameter of 10 mm, this results in pipe lengths of 300 to 700 mm).
  • the equivalent pipe diameter should preferably be 10 mm and larger values.
  • an inflow elbow 4 is provided, through which the axially arriving cooling air is deflected by 90 ° in the direction of the upper tube ends.
  • the air emerging from the air tube cooler at the lower end is passed via a corresponding guide in the form of a downpipe 5 to two fans 6 of axial type, which are arranged below or to the side of the oil pan of the engine block 2.
  • the fans 6 can - alternatively - also be arranged laterally next to the engine block, above the engine block or corresponding locations where the air leaving the fans can flow out as freely as possible.
  • the fans 6 can be driven by an electric drive 7 in a manner known per se. In motor vehicles, the fans 6 are expediently switched on and off in a temperature-controlled manner. The fans support the draft at low speeds.
  • the fans 6 must then be arranged laterally or above the engine block 2.
  • the diameter of the tubes 3 is appropriately circular, but other cross-sectional shapes are also possible.
  • the tubes are preferably widened at the ends to form a hexagon and connected in a heat-transfer-medium-tight manner via the hexagon side surfaces.
  • An “air tube cooler” is to be understood as a cooler in which the cooling air flows through the tubes 3, while the fluid to be cooled, in particular water, rinses the tubes 3 on the outside.
  • coolers for recooling liquid heated in the engine block or charge air coolers are mentioned as application examples. (With charge air coolers, the charge air rinses the pipes outside.)
  • coolers can also be used for the condensation of a cooling medium in the evaporative cooling (boiling cooling) known per se.
