Abstract

An arrangement of components for exchanging heat for motor vehicles with multiple cooling circuits comprising at least one pump, at least one control device and at least one heat exchanger. The arrangement is characterized in that a first cooling circuit is selectively connected with at least one or more additional cooling circuits to transfer thermal energy, and a selective fluid connection is provided between the additional cooling circuits by means of at least one control element.

Claims

1. An apparatus for exchanging heat in motor vehicles to raise or lower the temperatures of vehicle components comprising:

a pump to pump coolant through at least one cooling circuit;

a first cooling circuit that includes at least two heat exchangers and at least one heat reservoir;

a second cooling circuit that exchanges thermal energy with at least a first vehicle component;

a third cooling circuit that is selectively connectable with the second cooling circuit and that exchanges thermal energy with at least a second vehicle component; and

a plurality of control elements that selectively connects the first cooling circuit with at least one of the second and third cooling circuits and further independently selectively connects the second and third cooling circuits.
