Total cooling assembly for a vehicle having an internal combustion engine
First Claim
1. A total cooling assembly adapted for installation in an engine compartment of an automotive vehicle and defining an air flow path, the vehicle having an internal combustion engine, the assembly comprising:
- a heat exchanger module constructed and arranged to transfer heat from fluid coolant to air entering the air flow path and comprising front and rear faces such that air can pass in heat exchange relation across said heat exchanger module to absorb heat from fluid coolant flowing through said heat exchanger module, said heat exchanger module including an inlet and an outlet;
a cooling fan module carrying said heat exchanger module and comprising fan and an electric fan motor for drawing air across said heat exchanger module from said front face to said rear face of said heat exchanger module;
pump structure carried by said cooling fan module to circulate fluid coolant, said pump structure having at least one pump and an electric motor driving said pump;
a cooling circuit in which fluid coolant is circulated by the action of said pump structure, said cooling circuit permitting the fluid coolant to move from said pump structure to the engine, an outlet of said engine being constructed and arranged to communicate fluid coolant with the inlet to said heat exchanger module, the outlet of said heat exchanger module being fluidly connected with an inlet to said pump structure to return the fluid coolant to said pump structure, said cooling circuit including bypass structure fluidly constructed and arranged to connect an outlet of the engine with an inlet to said pump structure;
valve structure in said cooling circuit to regulate flow therethrough such that during a warm-up operating condition of the engine, said valve structure is controlled to permit fluid coolant flow from the outlet of the engine through said bypass structure and to the inlet of the pump structure, while substantially preventing fluid coolant to flow through said heat exchanger module; and
a controller to control operation of said at least one electric motor of said pump structure, said electric fan motor, and said valve structure.

Abstract
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. The cooling circuit permits the fluid coolant to move from the pump structure to the engine. An outlet of the engine is constructed and arranged to communicate fluid coolant with the inlet to the heat exchanger module. The outlet of the heat exchanger module is fluidly connected with an inlet to the pump structure to return the fluid coolant to the pump structure. The cooling circuit includes bypass structure constructed and arranged to fluidly connect an outlet of the engine with an inlet to the pump structure. Valve structure is provided in the cooling circuit to regulate flow therethrough. A controller controls operation of the at least one electric motor of the pump structure, the electric fan motor, and the valve structure. During a warm-up operating condition of the engine, the bypass structure permits fluid coolant to flow from the outlet of the engine to the inlet of the pump structure while substantially preventing fluid coolant to flow through the heat exchanger module.
