Patent ID: 7797954

Claim:
A cooling system, particularly for a motor vehicle, comprising: a refrigerating circuit ( 12 ), a cooling circuit ( 14 ) which is coupled to the refrigerating circuit ( 12 ) via a refrigerant/coolant heat exchanger ( 16 ), the coolant circuit ( 14 ) including a third-medium/coolant heat exchanger ( 34 ) and a first heat source ( 36 ) to be cooled, and means ( 42 , 44 , 47 ), by which the quantity of a coolant stream flowing via the refrigerant/coolant heat exchanger ( 16 ) can be controlled, including a first bypass line ( 47 ) for bypassing the refrigerant/coolant heat exchanger ( 16 ) and a first control valve ( 42 ) for the controllable apportionment of the coolant stream via at least one of the first bypass line ( 47 ) and the refrigerant/coolant heat exchanger ( 16 ), a second bypass line ( 38 ′) for bypassing the third-medium/coolant heat exchanger ( 34 ) and a second control valve ( 44 ) for the controllable apportionment of the coolant stream via at least one of the second bypass line and the third-medium/coolant heat exchanger ( 34 ), the cooling circuit ( 14 ) further including a sub-section ( 14 b ) bridged by the second bypass line ( 38 ′) and having, in addition to the third-medium/coolant heat exchanger ( 34 ), a second heat source ( 38 ) to be cooled and also a coolant pump ( 46 ) for circulating a coolant.
