Abstract (en)

A coolant system for a vehicle (10) with an internal combustion (IC) engine (12) includes a first coolant circuit (18) and air to liquid heat exchanger (14) for the engine (12) and a second coolant circuit (24) for a plurality of vehicle systems such as oil cooler, fuel cooler and charge air cooler (36, 48, 60). Additionally, an HVAC compressor (72) may be cooled. The control through the second cooling circuit (24) is maintained by valves (44, 56, 68, 78) for each heat exchanger (28, 30, 32, 34) and appropriate sensors (42, 54, 66, 74), along with the second coolant circuit pump output, and fan (86) output to achieve efficient heat transfer enabling a compact engine package. An alternate cooling system (90) includes a second heat exchanger (92) that provides a circuit for higher temperature operating heat exchangers (102, 104) and an additional circuit for a lower temperature operating heat exchanger (116).
