Embodiment Construction

[0028] figure 1 and figure 2 are two alternative cooling circuit arrangements in a vehicle according to the invention, each with an enlarged detail depiction of the area around connecting line 4 in the boxed area shown at the bottom left.

[0029] figure 1 Three cooling circuits 1 , 2 , 3 are shown, each having a heat exchanger 7 , 8 , 9 . A longer connecting line 5 , in particular a connecting pipe, is established as a fluid-conducting connection between cooling circuit 2 and cooling circuit 3 . The fluid conducting connection can be permanently closed by shut-off valves 6 (in particular non-return valves) at both ends of the connecting line 5 .

[0030] During the first filling of 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 simultaneously filled with the same coolant. After the first filling and closing of the shut-off valve 6, the longer connection line 5 is removed from th...

Abstract

A method for first filling of cooling circuits of a motor vehicle comprising at least two cooling circuits (1, 2, 3). During a filling sequence, the at least two cooling circuits (1, 2, 3) are connected via at least one fluid-conductive connection comprising a connecting line (4, 5) and established therebetween, and are filled simultaneously by via the fluid-conductive connection. The fluid-conductive connection is permanently closed after the filling sequence. The invention also relates to a vehicle comprising at least two cooling circuits.

Description

technical field [0001] The invention relates to a method for the first filling of a cooling circuit of a vehicle having at least two cooling circuits, and to such a vehicle having at least two cooling circuits. Background technique [0002] The use of cooling circuits for cooling motor vehicle components has been known for a long time. A coolant (for example water) circulating in the circuit is guided along the cooled component, it heats up and dissipates the absorbed heat again through a radiator, for example through a heat exchanger. During the production of the cooling circuit, the necessary coolant must be introduced once into the cooling circuit as a first filling. [0003] Many vehicles, such as hybrid vehicles, use two or more separate cooling circuits to cool firstly the components of the internal combustion engine and secondarily the components of the electric drive. For example, the same coolant can be used in cooling circuits at different temperatures. In the p...
