A thermal management system and method for a vehicle includes a cooling system having a variable cooling capacity and which is connectable to a heat-producing system of the vehicle. A control system is configured to increase the cooling capacity of the cooling system to a first predetermined level in response to the at least one input indicating an increase in the future heat load of the heat-producing system when a temperature of the cooling system is at least a predetermined temperature and the cooling system is operating below the first predetermined level. The control system is also configured to inhibit increasing the cooling capacity of the cooling system to the first predetermined level in response to the at least one input indicating an increase in the future heat load of the heat-producing system when the temperature of the cooling system is less than the predetermined temperature.

Thermal management system and method for a vehicle

A plurality of fans is connectable to a heat exchanger arrangement having a plurality of separated cooling loops. At least one of the fans is operable to move air through at least two of the cooling loops, and at least one other fan is operable to move air through at least one of the cooling loops. A control system includes at least one controller and is operable to control each of the at least one fan using a respective control strategy correlating temperature values with fan outputs, and to control each of the at least one other fan using a respective control strategy that is different from each control strategy used to control the at least one fan.

System and method for cooling fan control

A vehicle thermal management system includes an exhaust gas cooler configured to receive exhaust gas from the engine and to cool the exhaust gas before it is recirculated back into the engine. A valve is located downstream from the exhaust gas cooler, and is operable to control the amount of exhaust gas passing through the exhaust gas cooler. Intake air mixes with the exhaust gas downstream from the first valve. The mixed gas is then cooled by a mixed gas cooler before it enters the engine intake manifold. A coolant is circulated through the mixed gas cooler and a heat exchanger. The mixed gas rejects heat to the coolant via the mixed gas cooler, and the coolant rejects heat to the ambient air via the heat exchanger.

Thermal management system for a vehicle

A cooling system for cooling a plurality of heat producing systems includes a heat exchanger having a plurality of cooling zones, each of which has a respective inlet and outlet for facilitating flow of a respective temperature control fluid therethrough. Each of the respective temperature control fluids facilitates temperature control of a respective heat producing system. A plurality of fans cool the temperature control fluids flowing through the heat exchanger, and a fan or fans are disposed proximate each zone of the heat exchanger to provide air flow substantially independently from the air flow over the other cooling zones.

Cooling system and method for cooling a heat producing system

A vehicle thermal management system includes a temperature control fluid for controlling the temperature of at least a portion of a vehicle system. A pump is configured to pump the temperature control fluid through a heat exchanger to facilitate the transfer of heat between the temperature control fluid and ambient air. A fan is operable to move the ambient air across the heat exchanger to facilitate increased heat transfer. A control system is used to control operation of the pump and the fan. The control system is provided with operation data that includes optimized operating speeds for the pump and the fan to minimize power consumption, while maximizing heat transfer.

Thermal management system and method for a heat producing system

A fluid pump includes a pump housing having a housing cavity with an inlet and an outlet. A diffuser is located within the housing cavity, and includes a portion that is attached to the housing. The diffuser has a diffuser cavity, in which a stator assembly and canister are located. The canister provides a seal where it contacts the diffuser; this isolates the stator assembly from the fluid. The stator assembly provides a magnetic field which drives a rotor assembly. The rotor assembly rotates an impeller, which pumps the fluid from the inlet to the outlet.

Fluid pump having an isolated stator assembly

A fluid pump includes a pump housing having a housing cavity with an inlet and an outlet. An encapsulated stator assembly is positioned within the housing cavity and at least partially defines a fluid passage from the inlet to the outlet. A polymeric capsule member encloses and seals the encapsulated stator assembly, protecting the motor from, and providing heat transfer to, the working fluid. A stator provides a magnetic field which drives a rotor assembly. The rotor assembly rotates an impeller for pumping fluid from the inlet to the outlet.
