Definitions

  • the present invention relates to a method for first filling the cooling circuits of a vehicle with at least two cooling circuits and such a vehicle with at least two cooling circuits.
  • cooling circuits for cooling components of a motor vehicle are well known.
  • a coolant circulating in the circulation for example water, is guided along the component to be cooled, heats up and releases the absorbed heat at a heat sink, for example by means of a heat exchanger.
  • the required coolant as part of a first filling, must be introduced once in the cooling circuit.
  • Some vehicles also use two or more separate cooling circuits, for example hybrid vehicles for cooling components of the internal combustion engine on the one hand and components of the electric drive on the other hand.
  • the same coolant can be used at different temperatures in the cooling circuits.
  • a separate filling plant is used in the assembly line of the vehicle.
  • the object is achieved by a method for first filling the cooling circuits of a vehicle with at least two cooling circuits, wherein the at least two cooling circuits during filling via at least one established between the two cooling circuits fluid-conducting connection, comprising a connecting line, are connected and simultaneously by means of this fluid-conducting connection be filled, where the fluid-conducting connection is closed permanently after filling.
  • the first filling of the cooling circuits which is usually carried out during the manufacture of the vehicle, thus takes place simultaneously according to the invention, since the cooling circuits are connected during the Clearbehellung via a fluid-conducting connection line, so that the cooling medium from one cooling circuit to another - during normal operation of the vehicle separated - Can flow cooling circuit.
  • the fluid-conducting connection is closed after the first filling, so that there is no flow connection between the cooling circuits via the connecting line after the first filling. Since the same coolant flows according to the invention into the respective other cooling circuit during the first filling, the two cooling circuits also use the same coolant during normal operation.
  • the fluid-conducting connection is closed permanently after filling by closing one or two shut-off valves.
  • Two shut-off valves are particularly preferably used, one shut-off valve being assigned to one end of the connecting line.
  • the shut-off valves can preferably be closed irreversibly with a special tool.
  • the connecting line can remain in the vehicle after filling or can also be removed from the vehicle.
  • longer connecting lines for example longer than 15 cm, are preferably removed in order to save weight and costs.
  • return lines of the two cooling circuits can be connected to one another via the connecting line, or heat exchangers of the two cooling circuits can also be connected to one another via the connecting line.
  • At least one fluid-conducting connection is set up between the two cooling circuits, the fluid-conducting connection comprising a connecting line and a means for permanently closing the fluid-conducting connection between the two cooling circuits.
  • connection line may in particular be a connection tube.
  • the means for permanently closing may comprise at least one shut-off valve, wherein the shut-off valve is arranged in the connecting line or in a connection region of the connecting line to the cooling circuit.
  • the shut-off valve will be formed on the vehicle itself.
  • the connecting line may preferably connect mutually adjacent regions of the two cooling circuits with one another, in particular two heat exchangers lying close to each other or a heat exchanger with a cooling circuit of the other cooling circuit lying close to it, so that the connecting line can be short, in particular shorter than 50 cm, preferably shorter than 15 cm.
  • the cooling circuits can be fluidly connected to one another in series or in parallel by the connecting line or a plurality of connecting lines, so that either the coolant flows over from one cooling circuit to the next adjacent cooling circuit or overflows to several or all of the cooling circuits at the first filling of several cooling circuits.
  • the connecting line can have at least at one of its ends, preferably at both ends, a first coupling part for inserting the connecting line into a corresponding second coupling part on one of the cooling circuits. Between connecting line and cooling circuit so a connector is set up.
  • the first and the second coupling part is formed so that when removing the first coupling part from the second coupling part, the fluid-conducting connection is permanently closed.
  • the second coupling part is formed so that when removing the first coupling part from the second coupling part in the second coupling part, a sealing element is pressed by a first elastic element, such as a spring, against a sealing seat.
  • a first elastic element such as a spring
  • the first coupling part may comprise a needle which, when approaching the second coupling part, pushes a sealing element of the second coupling part away from its sealing seat.
  • the shape of the needle is not limited, as long as the needle can reach the sealing element and push away from its sealing position.
  • the first and second coupling part are formed so that when approaching the two coupling parts, a seal between the Is made coupling parts before the fluid-conducting connection is opened and the removal of the two coupling parts, the fluid-conducting connection is closed before a seal between the coupling parts is released.
  • Fig. 1 and 2 show two alternative cooling circuit arrangements in a vehicle according to the invention, each with an enlarged detail of the area around the connecting line 4 in the bordered area which is shown at the bottom left.
  • Fig. 1 three cooling circuits 1, 2, 3 are shown, each comprising a heat exchanger 7,8 and 9. Between lines of the cooling circuit 2 and the cooling circuit 3 is a longer connecting line 5, in particular a connecting hose, set up as a fluid-conducting connection.
  • the fluid-conducting connection can be permanently closed by means of shut-off valves 6, in particular non-return valves, at both ends of the connecting line 5.
  • the cooling circuits 1, 2, 3 the fluid-conducting connections via the connecting lines 4 and 5 are opened, so that the cooling circuits are filled simultaneously with the same coolant. After the initial filling and the closing of the shut-off valves 6, the longer connection line 5 is removed from the vehicle.
  • the shut-off valves 6 can be closed after the first filling with a special tool.
  • the connecting line 4 remains after the initial filling in the vehicle.
  • Fig. 2 differs only from that of the Fig. 1 in that the longer connection line 5 is also set up here from heat exchanger to heat exchanger, namely between heat exchanger 8 of cooling circuit 2 and heat exchanger 9 of cooling circuit 3.
  • Fig. 3 shows coupling parts 10, 11 for connecting one end of a connecting line 5 with a cooling circuit 1 in four stages of approach of the coupling parts 10, 11.
  • the second coupling part 11, which is formed on the cooling circuit 1 has as a sealing element 12 on a ball which by first elastic element 13, namely a spring, is pressed against a sealing seat 14.
  • the sealing seat 14 is formed at the end of the second coupling part 11 facing the first coupling part 10.
  • the sealing seat 14 has a central opening through which a needle 15 formed on the first coupling part 10 can protrude when approaching the two coupling parts 10, 11 in order to press against the sealing element 12 and thus push it away from its sealing seat 14.
  • the needle 15 preferably has a sealing cone 18, which seals between the first coupling part 10 and the needle 15.
  • the needle 15 in turn is preferably spring-loaded by a second elastic element 17 and thus presses the needle 15 and the cone 18 on the sealing surface or the sealing seat of the first coupling part 10 and closes without further force the fluid-conducting connection of the first coupling part 10.
  • the needle 15 When approaching the coupling parts 10, 11, the needle 15 is pressed against the sealing element 12 of the second coupling part 11, whereby the needle 15 is moved away from the sealing seat of the first coupling part 10 and upon further movement of the first coupling part 10 against the second coupling part 11 after overcoming the force of the first elastic element 13 and the sealing element 12 is moved away from the sealing seat 14 and thus releases a fluid-conducting connection.
  • the second elastic element 17 has a lower spring constant than the first elastic element 13, thereby opening, for example, the sealing surface between the needle 15 and the sealing seat of the first coupling part 10 first, then the sealing element 12.
  • At least one of the two coupling parts 10, 11 may have a radially encircling ring 19 through which one or more balls 20 can be pressed against an outer radially encircling groove 21 formed on the other coupling part 11, 10, so that the balls 20 engage in the groove 21 and the two coupling parts 10, 11 are fixed to each other.
  • the radially encircling ring 19 can have a conical course on the side facing the balls 20 in the axial direction in order to press the balls 20 into the groove 21 during axial movement of the coupling part 10, 11.
  • Fig. 4 shows the entire connecting line 5 with the first coupling parts 10 at its two ends and the respective counterparts, the second coupling parts 11, which are formed on the cooling circuits 1 and 2, respectively.
