Patent number: 6016774Abstract: A total cooling assembly adapted for installation in an engine compartment of an I.C. engine vehicle. The assembly includes a heat exchanger module to transfer heat from fluid coolant to air entering the air flow path and having front and rear faces such that air can pass in heat exchange relation across the heat exchanger module to absorb heat from fluid coolant flowing through the heat exchanger module. The heat exchanger module includes an inlet and an outlet. A cooling fan module carries the heat exchanger module and includes a fan and an electric fan motor for drawing air across the heat exchanger module from the front face to the rear face of the heat exchanger module. Pump structure is carried by the cooling fan module to circulate fluid coolant. The pump structure has at least one pump and an electric motor driving the pump. A cooling circuit is provided in which fluid coolant is circulated by the action of the pump structure.Type: GrantFiled: June 26, 1998Date of Patent: January 25, 2000Assignee: Siemens Canada LimitedInventors: Ron Bokkers, Alex Joseph, Bjorn Rossing

Patent number: 5970925Abstract: A heat exchanger module, a cooling fan module, a pump/fan module, and an electronics system control module are joined together in assembly to form a total cooling assembly for an automotive vehicle that is powered by an internal combustion engine. The cooling fan module is disposed directly behind the rear face of the radiator, and contains an electric motor-driven fan that draws ambient air across the radiator. At time of installation in a vehicle, the assembly is "dropped into" the vehicle engine compartment and secured in place. An electric motor-driven coolant pump module that pumps engine coolant through the engine and radiator, and an electronics system control module that controls the operation of the fan and pump motors also mount on the cooling fan module. When the vehicle has an air conditioning system, and/or turbo-charged engine, one and/or two additional heat exchangers form part of the heat exchanger module. The cooling fan module may comprise an axial flow fan or a ducted radial flow fan.Type: GrantFiled: August 4, 1998Date of Patent: October 26, 1999Assignee: Siemens Canada LimitedInventors: Andrew Lakerdas, Peter A. Kershaw, Alexander Joseph

Patent number: 5735342Abstract: A heat exchanger system including an outer duct housing a powered fan at one end. A heat exchanger is positioned in line with the fan within the duct and includes two nested pipes. Each pipe includes radially outward fins and radially inward fins. The radially inward fins on the outer pipe and the radially outward fins on the inner pipe are interdigitated. Appropriately positioned radial dividers extend fully between the bodies of the two pipes to divide the space between pipes into segments. End caps placed on the ends of the pipes include baffles which appropriately divide annular manifolds defined between the pipes and between the ends of the fins and the end caps in order that four passes are possible through the length of the heat exchanger. The radial dividers may be asymmetrically positioned to accommodate changes in volume with condensation of the fluid passing between the inner and outer pipes.Type: GrantFiled: May 17, 1996Date of Patent: April 7, 1998Inventor: Minoru Nitta
