    • 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).
    • 具有内燃(IC)发动机(12)的车辆(10)的冷却剂系统包括用于发动机(12)的第一冷却剂回路(18)和空气与液体热交换器(14)和第二冷却剂回路(24) ),用于多个车辆系统,例如油冷却器,燃料冷却器和增压空气冷却器(36,48,60)。 此外,HVAC压缩机(72)可以被冷却。 通过第二冷却回路(24)的控制由用于每个热交换器(28,30,32,34)和适当的传感器(42,45,66,74)的阀(44,56,68,78)保持,沿着 与第二冷却剂回路泵输出,并且风扇(86)输出以实现有效的热传递,使紧凑的发动机组件。 替代的冷却系统(90)包括第二热交换器(92),其提供用于较高温度的操作热交换器(102,104)的电路和用于较低温度的操作热交换器(116)的附加电路。
