Definitions

  • Embodiments relate to a method for first filling of the cooling circuits of a motor vehicle with at least two cooling circuits, and such a motor vehicle with at least two cooling circuits.
  • cooling circuits for cooling components of a motor vehicle has been known for a long time.
  • a coolant for example water
  • circulating in the circuit is guided along the components to be cooled, where it heats up and dissipates the absorbed heat again to a heat sink, for example by via a heat exchanger.
  • the necessary coolant must be introduced into the cooling circuit once as the first filling.
  • cooling circuits for example hybrid vehicles, for cooling components of the internal combustion engine firstly and components of the electric drive secondly.
  • the same coolant may be used in the cooling circuits at different temperatures.
  • a separate filling plant for each cooling circuit is installed in the motor vehicle assembly line.
  • German Patent Publication No. DE 10 2005 035 532 A1 describes a device for first filling of a fluid circuit, in particular a cooling circuit of an internal combustion engine for motor vehicles, comprising a small circuit and a large circuit which are switched by via a thermostat with a thermostat plate and a thermostat seat. Using the thermostat, it is possible to fill two cooling circuits alternately in the same filling process, controlled by the coolant temperature.
  • This device for first filling is complex and costly to produce and only functions with coolants at different temperatures.
  • Embodiments relate to a method for first filling of the cooling circuits of a motor vehicle with at least two cooling circuits, which is simple and economic to implement, and a motor vehicle with at least two cooling circuits which is prepared for such a method.
  • Embodiments relate to a method for first filling of the cooling circuits of a motor vehicle with at least two cooling circuits, which includes connecting, during filling, at least two cooling circuits via at least one fluid-conductive connection established between the two cooling circuits and including a connecting line, and simultaneously filling the at least two cooling circuits via this fluid-conductive connection, wherein the fluid-conductive connection is permanently closed after filling.
  • the first filling of the cooling circuits which is normally carried out during production of the motor vehicle, thus takes place simultaneously since, during the first filling, the cooling circuits are connected together via a fluid-conductive connecting line so that the cooling medium can flow from one cooling circuit to the other cooling circuit, normally separated during operation of the motor vehicle.
  • the fluid-conductive connection is closed after the first filling, so that after the first filling, there is no further fluidic connection between the cooling circuits via the connecting line. Since on first filling, according to the invention, the same coolant overflows into the other cooling circuit, the two cooling circuits normally use the same coolant.
  • a method for first filling of cooling circuits of a motor vehicle with at least two cooling circuits comprising: connecting, during a filling sequence, the at least two cooling circuits via at least one fluid-conductive connection established between the at least two cooling circuits; simultaneously filling the at least two cooling circuits via the at least one fluid-conductive connection; and permanently closing the fluid-conductive connection after the filling sequence.
  • a motor vehicle comprising: at least two cooling circuits; a connecting line to establish at least one fluid-conductive connection between the at least two cooling circuits; and a closure device to permanently close the at least one fluid-conductive connection.
  • a motor vehicle comprising: a plurality of cooling circuits; a connecting line to establish a fluid-conductive connection between the cooling circuits, the connecting line having coupling parts to connect the connecting line to a corresponding one of the cooling circuits; and a closure device at both ends of the connecting line to permanently close the fluid-conductive connection.
  • the fluid-conductive connection is permanently closed by closure of one or two shut-off valves.
  • two shut-off valves may be used, wherein one shut-off valve is assigned to each end of the connecting line.
  • the shut-off valves may be closed irreversibly using a special tool.
  • the connecting line may remain in the motor vehicle or be removed from the motor vehicle.
  • longer connecting lines for example, longer than 15 cm, may be removed to save weight and cost.
  • return lines of the two cooling circuits may be connected together via the connecting line, or respective heat exchangers of the two cooling circuits connected together via the connecting line.
  • a motor vehicle may have at least two cooling circuits, at least one fluid-conductive connection is established between the two cooling circuits, wherein the fluid-conductive connection comprises a connecting line and a closure device for permanent closure of the fluid-conductive connection between the two cooling circuits.
  • the connecting line may be a connecting hose.
  • the closure device for permanent closure may comprise at least one shut-off valve, wherein the shut-off valve is arranged in the connecting line or in a region where the connecting line joins the cooling circuit.
  • the shut-off valve may be arranged on the motor vehicle itself.
  • the connecting line may connect adjacent regions of the two cooling circuits, in particular, two adjacent heat exchangers, or a heat exchanger to an adjacent cooling circuit line of the other cooling circuit.
  • the connecting line may be formed shorter in length, such as, for example, less than 50 cm, or less than 15 cm.
  • the cooling circuits may be connected together fluid-conductively in series, or in parallel by the connecting line or plurality of connecting lines. In that way, on first filling of several cooling circuits, the coolant either overflows from one cooling circuit into the next adjacent cooling circuit or overflows to several or all cooling circuits simultaneously.
  • the connecting line may have a first coupling part at least at one of its ends, such as, for example, at both ends, for insertion of the connecting line in a corresponding second coupling part on one of the cooling circuits.
  • a plug-in connection is therefore established between connecting line and cooling circuit.
  • the first and the second coupling parts are configured such that on removal of the first coupling part from the second coupling part, the fluid-conductive connection is permanently closed.
  • the second coupling part is configured such that on removal of the first coupling part from the second coupling part, a sealing element in the second coupling part is pressed against a sealing seat by a first elastic element, for example a spring.
  • the first coupling part may have a needle which, on approach to the second coupling part, presses a sealing element of the second coupling part away from its sealing seat.
  • the form of the needle is not restricted as long as the needle can reach the sealing element and press this away from its sealing position.
  • the first and second coupling parts are configured such that when the two coupling parts are brought together, a seal is created between the coupling parts before the fluid-conductive connection is opened, and when the two coupling parts are moved apart, the fluid-conductive connection is closed before a seal between the coupling parts is broken.
  • FIG. 1 illustrates a diagrammatic view of a cooling circuit arrangement of a motor vehicle, in accordance with embodiments.
  • FIG. 2 illustrates a diagrammatic view of a cooling circuit arrangement in a motor vehicle, in accordance with embodiments.
  • FIG. 3 illustrates coupling parts for connection of one end of a connecting line to a cooling circuit, in four stages of bringing the coupling parts together, in accordance with embodiments.
  • FIG. 4 illustrates a connecting line with coupling parts at both ends, in accordance with embodiments.
  • FIGS. 1 and 2 illustrates alternative cooling circuit arrangements in a motor vehicle in accordance with embodiments, each with an enlarged detail depiction of the region around the connecting line 4 in the framed region which is shown at the bottom left.
  • a plurality of cooling circuits 1 , 2 , 3 which each comprise a heat exchanger 7 , 8 , 9 .
  • a longer connecting line 5 such as, for example, a connecting hose, is established as a fluid-conductive connection between the lines of the second cooling circuit 2 and the third cooling circuit 3 .
  • the fluid-conductive connection may be permanently closed by via shut-off valves 6 , such as, for example, non-return valves.
  • the shut-off valves 6 are arranged at both ends of the connecting line 5 .
  • the fluid-conductive connections via the connecting lines 4 and 5 are opened so that the cooling circuits are filled simultaneously with the same coolant.
  • the longer connecting line 5 may be removed from the motor vehicle.
  • a fluid-conductive connection is established between the heat exchangers 7 , 8 of the first cooling circuit 1 and the second cooling circuit 2 via the connecting line 4 , such as, for example, a hose with hose clamps, which is clearly visible in the detail enlargement of FIG. 1 .
  • the connecting line 4 may remain in the motor vehicle after the first filling.
  • FIG. 2 differs from that of FIG. 1 only in that the longer connecting line 5 is here also established from heat exchanger to heat exchanger, namely, between the heat exchanger 8 of the second cooling circuit 2 and the heat exchanger 9 of the third cooling circuit 3 .
  • coupling parts 10 , 11 for connection of one end of a connecting line 5 to the first cooling circuit 1 , in four stages of bringing the coupling parts 10 , 11 together.
  • the second coupling part 11 formed on the first cooling circuit 1 has a ball as a sealing element 12 , which is pressed against a sealing seat 14 by a first elastic element 13 , such as, for example, a spring.
  • the sealing seat 14 is formed at the end of the second coupling part 11 which faces 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 the two coupling parts 10 , 11 are brought together in order to press against the sealing element 12 , and hence push this away from its sealing seat 14 .
  • the needle 15 comprises 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 or cone 18 onto the sealing face or sealing seat of the first coupling part 10 , and without further force action closes the fluid-conductive connection of the first coupling part 10 .
  • 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 .
  • the sealing element 12 is also moved away from the sealing seat 14 and hence opens a fluid-conductive connection.
  • the second elastic element 17 has a spring constant that is less than the spring constant of the first elastic element 13 , so that, for example, the sealing face between the needle 15 and the sealing seat of the first coupling part 10 opens first, then the sealing element 12 following.
  • a ring seal 16 creates a seal between the coupling parts 10 , 11 before the fluid-conductive connection is opened, so that the coolant can flow through the second coupling part 11 , as indicated by arrows on the far right of the view in FIG. 3 .
  • the fluid-conductive connection is closed before the seal between the coupling parts 10 , 11 is broken.
  • At least one of the two coupling parts 10 , 11 may have a radially peripheral ring 19 , by which one or more balls 20 can be pressed against a outer radially peripheral groove 21 formed on the other coupling part 10 , 11 , so that the balls 20 engage in the groove 21 and the two coupling parts 10 , 11 are fixed together.
  • the radially peripheral ring 19 may have a conical form on the side facing the balls 20 , in order to press the balls 20 into the groove 21 on axial movement of the coupling parts 10 , 11 .
