Definitions

  • the invention relates to a device for cooling a heat engine, in particular a motor vehicle engine, comprising an extraction member, in particular a heat exchanger, for extracting heat from a heat transfer fluid, and means to circulate the heat transfer fluid in a circuit passing through the engine and the extraction member, said circuit comprising a thermally insulated reservoir for the fluid provided with an inlet pipe and an outlet pipe.
  • Such a device is described in FR-A-2 713 279.
  • This known device makes it possible to accelerate the rise in temperature of the engine, after a stopping period, when the temperature of the heat transfer fluid contained in the tank is still at a temperature relatively high when the engine is restarted.
  • the thermal insulation of the tank reduces the heat losses towards the atmosphere surrounding it, and even when valves placed on either side of the tank prevent any transfer of heat by convection between the fluid contained in the tank and that contained in the circuit in the vicinity thereof, heat transfer by conduction remains possible within the fluid, through the aforementioned valves.
  • the object of the invention is to remedy this drawback, and to provide an additional barrier with regard to the thermal losses from the tank to the outside thereof.
  • the invention relates in particular to a device of the kind defined in the introduction, and provides that said inlet and outlet pipes are connected to an expansion space permanently containing air so that, when the circulation of the fluid in the circuit is interrupted, air from said space is interposed, in these same pipes, between the fluid in the liquid state contained in the insulated tank and that contained in the rest of the circuit.
  • FIG. 1 shows two components of the cooling circuit of the drive motor of a motor vehicle, namely an insulated tank 1 and an expansion tank 2.
  • the expansion tank 2 is a conventional component of such a circuit , in the form of a bottle containing cooling fluid 3 in the liquid state up to a level 4, and air which occupies the volume 5 surmounting the level 4.
  • the reservoir 1 has the function, as described in detail in the aforementioned document, to keep warm a certain volume of coolant, when the vehicle engine is stopped and the fluid no longer circulates, so as to accelerate the warming up of the engine after its restart.
  • This tank is represented here in the form of a double-walled vase, the interval 6 of the double wall being under vacuum.
  • the vessel 1, elongated vertically, has at its upper part an opening 7 which is closed in leaktight manner by a removable plug 8.
  • the plug 8 is crossed by two pipes 9 and 10 opening at one end by respective fittings 11 and 12 to the outside of the vase and protruding inside of the vase at their opposite end.
  • the two pipes extend vertically side by side, being separated from one another by a thin wall 13.
  • the expansion tank 2 is interposed on a pipe 14 coming from the heat engine M of the vehicle by means of a thermostat or calorstat T and ending at the connector 11 so that the fluid heated by the engine reaches the line 9 constituting the inlet pipe of the insulated tank 1.
  • the thermostat T makes it possible to send a fraction of the flow of fluid leaving the engine, as a function of its temperature, in a cooling radiator R1 associated with a fan V1.
  • the pipe 14 enters the expansion tank 2 and exits through the bottom thereof, so that the fluid from the engine mixes with the mass of liquid 3, from which is taken the liquid which arrives in the pipe 9.
  • the fluid arriving through line 9 mixes with the liquid mass filling the reservoir, and the liquid leaves it through line 10 and the nozzle 12 to go to a radiator R2 for heating the passenger compartment of the vehicle, associated with a V2 fan.
  • the liquid having passed through the radiator R2 joins that leaving the radiator R1, the assembly being returned to the engine M by a circulation pump P.
  • a pipe 16 connects the air volume 5 of the expansion tank 2 to a small orifice 17 formed in the wall of the pipe 9, above the tank 1, and another small orifice 18, with a diameter of l 1 to 2 mm, is formed in the vertical wall 13 separating the lines 9 and 10, at the opening 7.
  • the level 4 of liquid in the expansion tank 2 is at a height between l orifice 18 and the lower ends of the pipes 9 and 10.
  • a three-way valve 20, shown schematically in the form of a pivoting valve, is housed in the plug 8. In the position indicated in solid lines, it allows the fluid to enter and exit from it respectively by the lines 9 and 10, as described above. In its position indicated in broken lines, it closes the pipe 10 and releases an opening 21 connecting between them the pipes 9 and 10 in the vicinity of the fittings 11 and 12. The fluid arriving in the upstream region of the pipe 9 then passes directly into the downstream region of the pipe 10, avoiding the reservoir 1. This makes it possible to reduce the mass of fluid in circulation, in certain phases of the operation of the device, as described in FR-A-2 713 279.
  • FIG. 2 shows an insulated tank 1 practically identical to that of FIG. 1, serving at the same time as an expansion tank to replace the tank 2.
  • the tank contains an air volume 30, above a level 31 itself located higher than the lower ends of the pipes 9 and 10.
  • the orifice 17 for communication with the pipe 16 is replaced by an orifice 32 connecting the pipe 9 to the volume 30.
  • the lines 9 and 10 are filled with air from volume 30, through orifices 32 and 18.
  • the reservoir of FIG. 3 differs from that of FIG. 2 in that it is provided for the inlet of fluid through line 10 and the outlet of fluid through line 9. Port 32 is replaced by port 40 connecting line 10 to air volume 30.
  • the reservoir of Figure 4 is similar to that of Figure 3, except that the pipe 10 does not extend to the liquid level 31 and opens into the air volume 30, the orifice 40 being removed .
