A cooling system for a heat producing system includes a heat exchanger in fluid communication with the heat producing system. The heat exchanger is configured to receive a temperature control fluid therethrough. A first fan is operable in a first rotational direction to move air through the heat exchanger in a first direction. A second fan is disposed radially adjacent to the first fan, and is operable in a second rotational direction opposite the first rotational direction to move air through the heat exchanger in the first direction. A control system, including at least one controller, is provided for controlling operation of the fans.

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.

A fluid valve for use in proportioning/mixing fluid between at least one input and at least one output. The fluid valve including a rotary actuated diverter for controlling fluid flow between the inlet(s) and outlet(s). The fluid valve may be configured to support proportioning any number of fluids, including liquids and gases, for any number of applications, including automotive and industrial applications.

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.

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.

A water pump assembly for controlling the flow of temperature control fluid in an internal combustion engine. The water pump assembly includes a housing with an inlet, an outlet and an electric motor assembly for causing fluid to flow from the inlet to the outlet. A housing includes a mounting flange for mounting the water pump to an engine. The mounting of the water pump permitting direct flow into or out of the engine from the water pump.

An auxiliary oil filtration system and method for filtering oil in an engine is provided. The auxiliary oil filtration system consists of an auxiliary filtration device, an integral oil transfer pump controlled by an electric motor and that is in electrical communication with an electrical control unit, an electronic pressure sensor, fluid conductors, and means for connecting hardware. The auxiliary filtration device is separate from the primary engine lubrication system, and includes a media supply reel having a roll of filtering media thereon which is moveable to a take-up reel. A media indexing system advances the media supply reel as the filtering media becomes plugged. An electronic pressure sensor dictates the advancement of the filtering media when a pre-determined differential pressure across the filtering media is attained. When all of the filtering media has been transferred from the supply reel to the take-up reel, the cartridge is replaced.

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.

An electric air charger for use with an internal combustion engine is disclosed. The air charger includes an impeller for supplying air to the engine. A housing surrounds the impeller and has an air inlet and an air outlet adapted to couple the air supplied by the impeller to the engine. The air inlet and the air outlet are substantially axially aligned. The air charger further includes an electric motor for controllably rotating the impeller.

Flow-through controllable air charger

A fluid pump includes a housing having a passage therethrough with an inlet and an outlet. An impeller is positioned within the housing and includes an impeller axis, an inlet side and an outlet side. The impeller is axially supported only at the outlet side, and is configured to direct fluid at an acute angle relative to the impeller axis. A switched reluctance motor is secured to the housing for rotating the impeller for pumping fluid from the inlet to the outlet.

Fluid pump

An oil pump for use in a vehicle engine includes a rotary pump for pressurizing oil to be pumped, and a movable piston cooperating with the rotary pump to facilitate metering of oil to and from the pump. The oil metering device is incorporated directly into the pump by means of a cam-actuated piston or a spring-loaded piston which cooperates with a displacement chamber for metering oil. Alternatively, a solenoid-actuated piston may be provided for selectively blocking pressurized fluid from entering a spring-loaded diaphragm chamber. The diaphragm is stroked alternatively by a spring and by oil pressure for metering of fluid therethrough in desired increments.
