Definitions

  • the invention relates to a cooling device in a motor vehicle for liquid cooling of its internal combustion engine with features according to the preamble of claim 1.
  • the invention is based on a prior art according to DE-A 14 26 185, in which a large-volume calming space is provided as part of the cooling device for a motor vehicle engine in the form of a container.
  • This forms an additional volume and is connected via a riser pipe with a relatively large diameter to a ventilation line which is laid between the inlet-side water tank of the cooler and the expansion tank.
  • Said riser pipe starts at a point near the entry point of the container.
  • an overflow transverse wall is provided in the middle of the container from the bottom of the container, which rises vertically and extends approximately to the middle height, and which is intended to promote the separation of air inclusions carried in the suction line to the riser pipe.
  • This type of design and volume dimensioning of the bubble separator according to the invention make it possible to achieve a noticeable reduction in the cooling water flow rate.
  • the air bubbles to be separated are practically forced up on the inclined wall of the bubble separator and introduced directly into the riser pipe. This enables a very high degree of separation to be achieved; the water pump only sucks in air-free cooling water as far as possible, which means that cavitation damage with the resultant partial destruction of engine components or the total failure of the engine can be effectively avoided.
  • the fact that the coolant flowing through the heating circuit is also included in this bubble separation not only ensures that the entire cooling system quickly becomes bubble-free, but also effectively prevents cooling water that is too strongly mixed with air bubbles from being used in the heating circuit could reduce the heating effect.
  • a cooling water expansion tank 6 is arranged above the cooler 3.
  • a line 7 with the check valve 15 connected connects the cooling water expansion tank 6 to the upper water tank of the cooler 3, while a line 8 connects the cooling water expansion tank 6 to the line 4 which extends between the lower water tank of the cooler 3 and the water pump 12.
  • a line 9 branches off from the engine 1, which leads to a heat exchanger 10 and, like the latter and a line 11 extending from it, is part of a heating circuit.
  • a bubble separator 13 is installed in the line 4 shortly before the water pump 12 connected to the motor 1.
  • the heating circuit 9, 10, 11 opens with its line 11 in flow upstream of the bubble separator 13 into line 4.
  • a riser pipe is designated, in which a check valve 15 is also installed and which is connected on the one hand to the expansion tank 6 and on the other hand to the bubble separator 13.
  • the bubble separator 13 as can be seen from the drawing, is designed as a funnel-shaped extension of the riser pipe 14, arranged at its lower end and connected to the line 4 with its expanded funnel entry base 17.
  • the engine 1 is vented via line 16.
  • Fig. 2 shows schematically an embodiment of the bubble separator 13, which is delimited by conical wall parts 18.
  • the bubble separator 13 tapers upwards from the funnel inlet base 17 lying in the plane of the line 4 to the point where it enters the riser pipe 14.
  • Fig. 3 shows schematically an embodiment of the bubble separator 13, in which the latter is delimited by an inclined wall 19 and a vertical wall 20, the inclined delimitation wall 19 being arranged closer to the cooler 3 in terms of flow and for an inclined upward passage of excreted air to the riser pipe 14 cares.
  • the bubble separator 13 generally has a holding volume of at least 3 times the amount of liquid that the inlet cross section of the water pump 12 allows.
