A method of minimizing overall power consumption of a vehicle cooling system includes performing a hardware selection phase, performing an actuator position selection phase, and configuring operation of selected hardware components of the vehicle cooling system at a selected actuator position combination when the vehicle is operating in a predefined driving condition.

Vehicle thermal system for reduced fuel consumption

A cooling system for an internal combustion engine of a motor vehicle having a rotating member and using coolant in a liquid cooling system, is provided that comprises a radiator for dissipating the heat from the coolant, an electric pump for pumping the coolant through the cooling system, a mechanical pump operatively connected to the rotating member for pumping coolant through the cooling system, and a clutch for disengaging the second pump for minimizing the parasitic loss of the system and improving total fuel economy of the vehicle.

Series electric-mechanical water pump system for engine cooling

A cooling fan system includes an engine driven mechanical fan and an electrically driven fan. The mechanical fan and the electrical fans are placed in series within a common shroud that directs air between them. In one application, the electrical fan generates an axially directed air flow and the mechanical fan produces a radially directed air flow. The electrical fan is rotated counter to the mechanical fan.

Cooling fan system for a motor vehicle

A flow regulating valve for air conditioning systems is shown in which a body member (26, 26a-26e) is provided with a passageway (28, 28a-28f) which results in regulating flow of refrigerant into the evaporator of the air conditioning system under normal conditions. Under severe operating conditions, e.g., high ambient temperature and low or idle speeds, the system refrigerant pressure rises. This increases pressure in the evaporator and an increase in the saturation temperature of refrigerant in the evaporator. This increase in temperature is sensed by a thermostatic metal element (44, 80, 88) of the regulating valve which moves to increase restriction to the flow of the refrigerant fluid through the valve thereby decreasing pressure of the refrigerant entering the evaporator. In several embodiments the thermostatic metal element is in the form of a helix (44) with one end fixed to the body member and the opposite end attached to a sleeve (38, 38d) in certain embodiments and an end cap (54, 60, 68) in other embodiments to rotate the sleeve or end cap to restrict fluid flow in an auxiliary passage. In other embodiments the thermostatic metal element is a relatively straight strip (80, 88) having one end fixed to the body member and its opposite end, in one embodiment, movable toward and away from an auxiliary inlet port (34) and in another embodiment the opposite end is attached to a block (94) having a relatively smaller effective passage (29e) movable into and out of alignment with a larger passage (31e) to change the effective level of flow restriction.
