Abstract: 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.

Abstract: The present invention provides a rotary axial fan and a stator fan for moving air through a heat exchanger for an internal combustion engine cooling system. The fan includes a hub and primary fan blades extending radially from the hub. An annular shroud is attached to the primary fan blades and supported coaxially with the central axis to limit the radial flow of air along the primary fan blades. A plurality of secondary fan blades are interposed between the primary fan blades and each have a first end attached to the annular shroud and terminate in a second end that is not attached to the hub. The stator fan includes a shroud with an array of stator fan blades supporting a hub for the radial axial fan. The size, orientation and material characteristics of the stator fan blades improve sound reduction and heat transfer of the rotary axial fan assembly.

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.

Abstract: 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.

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.

Abstract: A centrifugal fluid pump for circulating fluid through an engine's cooling system includes a body configured to be at least partially received within a bore in the engine, a shaft having an impeller rotatably connected to the body, the impeller being positioned to move fluid through the engine, and a shroud supported on the body and positioned between the duct and the impeller when the body is at least partially received within the bore. The shroud has an opening to permit the movement of fluid to the impeller and may be configured to engage an inner surface of the bore. The shroud remains stationary with respect to the bore as the shaft and the impeller rotate and the shroud and the bore cooperate to inhibit fluid from passing between the inner surface of the bore and the shroud to a position that is upstream of the shroud.

Abstract: A fluid cleaning system includes a fluid source connected to a pump that is used to increase the pressure of the fluid. A two-way valve selectively allows the higher pressure fluid to flow back into the tank, or to flow to a rotary union. The union has a nozzle attached to it to provide a fluid stream to contact an object, such as a workpiece, to be cleaned of dirt, debris, or surface irregularities. The union is attached to a robot arm, and contains locating features which allow the fluid stream to be accurately located relative to the workpiece. This allows the entire system to be automated, thereby providing advantages such as speed and efficiency.

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.

Abstract: 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.
