Definitions

  • the invention relates to a water cooling system for an internal combustion engine charged by means of a mechanical supercharger, wherein a main circuit - essentially consisting of a water pump, water cooler and internal combustion engine - is assigned a secondary circuit for the supercharger, which works with the same coolant.
  • Either a separate cooler can be provided for the loader or, if possible, a direct installation in the main water circuit.
  • the latter solution saves housings and cables.
  • the invention is therefore based on the object, in a system of the type mentioned, to design the secondary circuit independently of the temperature of the coolant in the main circuit, so that there is the possibility of cooling or heating the mechanical charger as desired.
  • this is achieved in that the coolant in the secondary circuit is driven by a conveying device which in turn is fed from the main circuit, preferably downstream of the pump, and that this coolant is cooled in a part of the water cooler arranged in the main circuit.
  • the advantage of the invention can be seen in particular in the fact that only one cooling unit is required and that no external drive, for example a conventional electric pump, has to be provided for the secondary circuit.
  • the concept is therefore inexpensive, in particular if an ejector is provided as the conveying device, which ejector can be a simple plastic injection molded part in the intended application.
  • the water cooler is a downdraft cooler
  • partitioning in the water cooler is carried out by means of partition walls in the upper and in the lower water tank, and if a compensating panel is provided in the partition wall of the lower water tank.
  • the partitions are then to be sprayed as integral parts of the water tanks using the same tool.
  • the secondary circuit is also filled via the compensating orifice. Even if the coolant in the secondary circuit is greatly expanded, it can escape through the compensating orifice.
  • a bypass line with a regulated thermostatic valve is arranged parallel to the water cooler. This makes it possible, for example, in partial load rich the internal combustion engine to heat the charger instead of cooling.
  • cooling chambers are formed on the housing parts in the space left free by the inner sections of the displacers or the conveying spaces, which communicate via a connecting line and can be connected to a cooling circuit via a connecting line.
  • the internal combustion engine 1 shown in FIG. 1 is a diesel engine or a 4-stroke gasoline engine.
  • the heat given off on the combustion chamber walls of this machine is dissipated to the ambient air by water cooling.
  • the water cooler 2 required for this is a downflow cooler with a vertical water flow from the upper water tank 3 to the lower water tank 4.
  • An expansion vessel 42 is connected to the lower water tank 4 via a filling line 44.
  • a ventilation line 43 leads from the line 8 to the expansion vessel 42.
  • the cooling water regulator which ensures that a fluctuation in the water temperature with the engine load and the engine speed is avoided, is not shown, since it is not essential to the invention. So much for the main circuit.
  • the mechanical loader 9 which is also driven by the belt 5 already mentioned.
  • the secondary coolant circulates out of the loader via a delivery device 10, here an ejector.
  • this ejector is connected to the main cooling circuit, preferably downstream of the water pump 6.
  • a drive line 11 runs from the pressure-side outlet of the water pump to the ejector.
  • the ejector conveys the coolant through a feed line 12 into the upper water tank 3 of the cooler 2, from whose lower water tank 4 the now cooled water reaches the charger 9 via the return line 13.
  • the water boxes of the cooler common to the main cooling circuit and secondary cooling circuit are each in two compartments divided. This is accomplished by dividing walls 14, 15 within the water boxes. So that the secondary circuit can be filled with water at all, a compensating orifice 16 in the form of a simple opening is arranged in the lower partition 15, and the upper water tank 3 is connected to the expansion vessel 42 via a second vent line 45.
  • a bypass line 17 is arranged parallel to the cooler between the feed line 12 and the return line 13.
  • a thermostatic valve 18 At the mouth of the flow line 12 there is a thermostatic valve 18. This is, for example, a short-circuit-controlled regulator in which the coolant only circulates in the charger after starting, i.e. that the flow line to the cooler is blocked.
  • a particularly fine adjustment of the charge air temperature in the charge air line 19 to the engine to predetermined objectives can be carried out if the thermostatic valve 18 is controlled by an on-board computer 20.
  • Input signals 21 and 22 to the computer form operating variables such as, for example, the measured charge air temperature and the control rod travel of the injection pump, as the latter is shown symbolically.
  • the mechanical supercharger to be cooled by means of secondary water is described below using a scroll compressor.
  • the intake line 24 for the fresh air is shown in Fig. 1.
  • Fig. 1 For the sake of clarity, these two lines as well as the flow and return lines 12 and. 13 shown in the simplest way.
  • the water flow within the charger is also shown schematically in FIG. 3.
  • this loader is shown in longitudinal section.
  • Such displacement machines the mode of operation of which is known from the already mentioned DE 26 03 462 C2
  • the working medium for example consisting of air or an air / fuel mixture.
  • crescent-shaped work spaces are enclosed along the delivery spaces 27, 27 'between the displacer 32 and the webs 30, 30' of the delivery spaces, which work from the inlet 33 through the delivery spaces to the outlet 34 move. In doing so, their volume decreases increasingly with a corresponding increase in the working fluid pressure.
  • the temperature of the conveyed medium also increases.
  • the charger has a two-part spiral housing 31.
  • the delivery spaces 27, 27 ' are incorporated in the side walls 28, 28' in the manner of a spiral slot.
  • the delivery spaces each run from an inlet 33 arranged at the outer spiral end to an outlet 34 arranged at the inner spiral end.
  • the two inlets 33 and outlets 34 communicate with one another in a manner not shown and are on the one hand with the suction line 24 (FIG. 1) and the charge air line 19 connected.
  • the disk-shaped displacer 32 with strip-shaped displacement bodies 35, 35 'arranged on both sides of the central disk is held with a hub 36 with the interposition of a roller bearing 27 on an eccentric disk 38 of the central drive shaft 25.
  • a second eccentric arrangement 39 is provided for guidance on the outer circumference of the displacer.
  • the two eccentric arrangements 25 and 39 are connected via a toothed belt 40.
  • the annular water chambers 26, 26 ' are attached to the end faces of the loader by suitable means.
  • the heat exchange surface 28,28 'ribs 29 are provided on the outer surface of the side walls, which protrude into the water chambers.
  • the heat accumulated in the webs 30, 30 ' can be dissipated if the ribs 29 are formed directly as an extension of the webs 30, 30'. It is understood that in this case the ribs also have a spiral course.
