Engine compartment cooling system
First Claim
1. In combination with an engine compartment having an engine, a hood, and at least two front quarter panel side walls defining an interior engine compartment, an engine compartment cooling system, comprising:
- (a) a clear hole in at least one of the side walls positioned between a passenger compartment and a forward portion of a fender wheel well;
(b) at least one axial fan assembly having a fan housing, a plurality of fan blades, a motor shaft, and a fan motor, the fan assembly mounted in the clear hole;
(c) a fan motor control system operatively connected to a first temperature sensor for sensing a temperature of the engine compartment and sending a first signal data to a controller operable to optimize a fan speed of the fan assembly based on the temperature of the engine compartment; and
(d) a heated air flow path which originates from the engine and is exhausted outwardly through the fan assembly into an ambient air flow for cooling of the engine compartment.

Abstract
In combination with an engine compartment having an engine, a hood, and at least two front quarter panel side walls defining an interior engine compartment, an engine compartment cooling system, is provided which includes a clear hole in at least one of the side walls positioned between a passenger compartment and a forward portion of a fender wheel well. At least one axial fan assembly has a fan housing, a plurality of fan blades, a motor shaft, and a fan motor. The fan assembly is mounted in the clear hole. A fan motor control system is operatively connected to a first temperature sensor for sensing a temperature of the engine compartment, and sending a first signal data to a controller operable to optimize a fan speed of the fan assembly based on the temperature of the engine compartment. A heated air flow path originates from the engine compartment and is exhausted outwardly through the fan assembly into an ambient air flow for cooling of the engine compartment.

7. In combination with an engine compartment having an engine, a hood, and at least two front quarter panel side walls defining an interior engine compartment, a thermal management cooling system, comprising:
-
(a) a first clear hole in at least one of the side walls positioned between a passenger compartment and a forward portion of a fender wheel well; (b) a first axial fan assembly having a fan housing, a plurality of fan blades, a motor shaft, and a fan motor, the fan assembly mounted in the first clear hole; (c) a heated air flow path which originates from the engine and is exhausted outwardly through the fan assembly into an ambient air flow for cooling of the engine compartment; (d) a second clear hole in at least one of the side walls positioned between the passenger compartment and a forward portion of the fender wheel well; (e) a remote mount fluid cooler assembly mounted in the second clear hole including a temperature control fluid, a second temperature sensor for sensing a temperature of the temperature control fluid, a heat exchanger for transferring heat between the temperature control fluid and ambient air, a second fan operable to move the ambient air across the heat exchanger, a pump operable to pump the temperature control fluid through the heat exchanger, and a valve in fluid communication with the pump and the heat exchanger; and (f) a control system operatively connected to the temperature sensors and the valve, wherein the temperature sensors and sending a first and second signal data to a controller operatively connected to the temperature sensors, the fans, and the valve, and programmed with operation data providing optimized operating speeds for the fans and temperature control fluid flow rates for combined operation of the fans, and optimized temperature control fluid flow from the pump to the heat exchanger which are based at least in part on the operation data and signals received from the temperature sensors.
