  • Publication number: 20060254291
    Abstract: 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.

  • Publication number: 20060185626
    Abstract: 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.

  • Publication number: 20060185364
    Abstract: 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.
