Definitions

  • This invention relates to a cooling assembly and more particularly to a total cooling system that includes various pump and valve configurations to provide efficient fluid circulation and heat rejection in a engine compartment of an internal combustion engine of a vehicle.
  • An internal combustion engine requires heat rejection generally either by air or liquid.
  • liquid cooled engines are most common.
  • Liquid engine cooling is accomplished by a engine-driven coolant pump (commonly referred to as a water pump) mounted on the engine block and operated directly by the engine.
  • the pump forces coolant through passages in the engine, where the coolant absorbs engine heat, then the coolant passes through a radiator where heat is rejected, and finally coolant is returned to the pump inlet to complete the fluid circuit.
  • a fan driven either directly from the engine or by an electric motor, is used in may cases to draw ambient air across the radiator so that heat is rejected at the radiator by transferring heat from the coolant to the ambient air, thus cooling the engine.
  • a conventional thermostat controls the flow of pumped coolant through the radiator in relation to coolant temperature.
  • the thermostat controls flow through the radiator until the coolant reaches a sufficiently hot temperature to cause the thermostat to allow flow through the radiator such that the radiator may effectively limit engine temperature.
  • the thermostat performs a form of coolant temperature regulation that establishes a desired operating temperature for the engine once the engine has fully warmed up while inherently allowing the coolant to heat more rapidly when the engine is started from a cooler condition.
  • cooling system is effective in operation, to improve fuel economy, it is preferable to operate the cooling fan and water pump motor based on cooling requirements, rather than on the r.p.m. of the engine.
  • An object of the invention is to fulfill the need referred to above.
  • this objective is obtained by providing a total cooling assembly adapted for installation in an engine compartment of an automotive vehicle and defining an air flow path.
  • the vehicle has in internal combustion engine.
  • the assembly includes a heat exchanger module constructed and arranged 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.
  • 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.
  • a total engine cooling assembly for an internal combustion engine is shown, provided in accordance with the principles of the present invention.
  • the internal combustion engine is schematically illustrated and designated by the letter E.
  • the cooling assembly 10 comprises a cooling fan module, generally indicated at 12, an electric coolant pump structure, generally indicated at 14, an electronic systems control module 16, and a heat exchanger module, generally indicated at 18.

  • the heat exchanger module 18 is joined with the cooling fan module 12 by suitable joining means, such as fasteners, to form the total cooling assembly 10.
  • the heat exchanger module 18 comprises a radiator 20 and, when air conditioning is provided, an air conditioning condenser 22 is disposed adjacent to the radiator 20.
  • Radiator 20 is conventional, comprising right and left side inlet header tabs 24R and 24L, and a core 25 disposed between the two header tab 24R, 24L.
  • the right side header tank 24R is an inlet tank and includes an inlet tube 26 at an upper end thereof.
  • the inlet tube 26 is fluidly coupled with a T-type connector 28 of the pump structure 14, the function of which will become apparent below.
  • the left side header tank 24L is an outlet tank and includes an outlet tube 30 near lower end thereof which is fluidly connected to an inlet (not shown) of the pump structure 14.
  • the pump structure 14 comprises first and second pump-motors P1 and P2, respectively, each having a pump being driven by an associated electric motor.

  • Valve structure 74 is provided in the bypass structure for controlling flow therethrough.
  • inlet 26 of the radiator 20 is fluidly connected to one end of the T-type connector 28.
  • the other end of the T-type connector 28 is fluidly coupled to the engine E, the function of which will be explained below.

  • Fan 46 is disposed concentrically with a surrounding circular-walled through opening 50 in the panel structure 32.
  • An expansion tank 52 is mounted on the cooling fan module 12 to receive, from connector 33 of the right header tank and via tube 35, coolant during certain operating conditions.
  • Radiator 20 and condenser 22 each define a heat exchanger serving to reject heat to ambient air.
  • Engine coolant in the case of the engine cooling system, and refrigerant, in the case of the air conditioning system, flow through passageways and their respective heat exchangers while ambient air flows across the passageways from the front face to the rear face of the heat exchanger module 18, in a direction of arrows A in FIG. 1.
  • the air passes successively through the condenser 22 and the radiator 20.
  • Each heat exchanger typically is constructed with fins, corrugations, or other means to increase the effective heat transfer surface area of the passageways for increasing heat transfer efficiency.
  • the flow of ambient air across the heat exchanger module 18 forms a effluent stream, with such flow being caused either by the operation of the fan 46 by motor 48 to draw air across the heat exchanger module 18 or by a ram air effect when the vehicle is in forward motion, or a combination of both.

  • Module 16 comprises electronic control circuitry that acts upon the signals to control the operation of electric motors of the pump-motors P1 and P2, fan motor 48 and to control the operation of the valve structure 74 and heater valve 68. Since control module 16 operates the fan 46 and pump structure 14 at speeds based on cooling requirements rather than engine r.p.m., engine power is used more efficiently and thus, fuel economy is improved.
  • Examples of other signal sources controlled by the control module 16 include temperature and/or pressure sensors located at predetermined locations in the respective cooling and air conditioning systems, and/or data from an engine management computer, and/or data from an electronic data bus of the vehicle's electrical system.
  • the control module 16 includes a controller or microprocessor which processes signals and/or data from the various sources to operate the pump-motors and fan such that the temperature of coolant, in the case of the engine cooling system, and the pressure of refrigerant, in the case of the air conditioning system, are regulated to the desired temperature and pressures, respectively.
  • FIG. 2 is a schematic illustration of the total cooling system 10 of FIG. 1.
  • the pump structure 14 comprises the two pump-motors, P1 and P2.

  • Connecting line 70 is in fluid communication with the bypass structure 43.
  • the T-type connector 28 permits coolant to flow through to the radiator inlet 26 and also to valve 74 disposed in the bypass structure 43 and return to the pump-motor P1.
