Definitions

  • the invention relates to a cooling system for internal combustion engines according to the preamble of patent claim 1.
  • a cooling system according to the preamble of claim 1 is described.
  • the coolant is filled through a filling opening of the expansion tank when the cooling system is filled. From there it has to flow into the heat exchanger. The way there does not emerge from GB-A 2 116 921. There is also no information about the draining of the cooling system.
  • the invention has for its object to provide a generic cooling system that can be quickly filled and emptied.
  • expansion tank and the blower jacket are made in one piece and are designed as a carrier for the cooler.
  • Such a carrier has the advantage that only a part has to be attached to the vehicle or to the internal combustion engine.
  • the carrier can be made of plastic or metal, for example, so that the heat exchanger forming the cooler can be attached directly to the carrier without connecting lines.
  • the fact that only one hose line package or a plug-in pipe connection has to be guided from the internal combustion engine to the carrier reduces the outlay on assembly and maintenance, since the parts can be preassembled and the entire package can therefore be replaced, for example.
  • this has, at the geodetically lowest point on the carrier, an opening which opens into the surroundings and can be closed with a screw plug, which is connected to the interior of the expansion tank and the cooler.
  • the opening and the screw plug are designed such that, in a screwed-in position of the screw plug, the interior of the expansion tank is blocked off from the interior of the cooler and from the environment, and the screw plug in a venting position connects the interior of the expansion tank and the interior of the cooler releases and at the same time shuts off both interiors from the environment.
  • the screw plug is completely removed from the opening, so that the coolant in the cooler and in the expansion tank can be drained quickly and completely.
  • the screw plug is up to a venting position screwed or unscrewed and a quick filling of the system is made possible by the direct connection of the interior of the expansion tank and cooler.
  • the screw plug is then screwed in completely and the connection between the cooler and the expansion tank, which is normally not required and desired, is shut off.
  • the expansion tank 1 includes a blower jacket 1 and a surge tank 2, the carrier being designed so that a cooler 3 can be attached to it or to the surge tank 2 directly without hose connections or the like.
  • a filler neck 4 opens directly into the expansion tank 2.
  • the rear wall 5 (FIG. 2) of the expansion tank can be made of a transparent material and have one or more markings 6 for, for example, minimum and maximum coolant level.
  • the coolant supply line 7 and the coolant discharge line 8 to and from the cooler are routed to the blower jacket 1, so that only short connecting lines to the internal combustion engine are required.
  • an opening 9 is provided, which extends via a connection 10 into the interior of the expansion tank 2 and via the cooling fluid supply line 7 into the interior of the cooler 3.
  • connection 10 to the interior of the expansion tank 2 is closed by the screw plug 11 in its screwed-in position. If the screw plug 11 is brought into the venting position 12, there is a liquid connection from the interior of the cooler 3 via the coolant supply line 7 and the connection 10 to the interior of the expansion tank, and the coolant filled via the filler neck 4 passes directly into the entire cooling system. For normal operation of the internal combustion engine, the screw 11 is screwed in completely and the connection 10 is shut off. If the carrier is attached directly to the internal combustion engine, the coolant supply line 7 and coolant discharge line 8 can be designed such that they can be connected directly to the coolant pump of the internal combustion engine and to an outlet from the internal combustion engine. In the interior of the expansion tank 2 continues a connection piece 13, which forms a bypass return line to the coolant pump of the internal combustion engine. Otherwise, the cooling system according to the invention is suitable for any type of cooling liquid, such as oil or water.
