An engine cooling system may include a housing forming an enclosed duct having an air intake opening, an air intake door, an exhaust opening, and an exhaust door; at least one heat exchanger positioned within the duct such that ambient air entering the air intake opening flows through the duct to contact the at least one heat exchanger and exits the duct through the exhaust opening; and a controller connected to vary a degree that one or both of the air intake door and exhaust door is open to modulate a mass flow rate of ambient air contacting the at least one heat exchanger to vary a heat transfer from the at least one heat exchanger to the ambient air in the duct to maintain a temperature of a fluid within the at least one heat exchanger within a preferred temperature range.

Engine cooling system

An engine cooling system may include a housing forming an enclosed duct having an air intake opening, at least one heat exchanger positioned within the duct such that ambient air entering the air intake opening contacts the at least one heat exchanger, at least one radiator circulating coolant for the engine, at least one radiator positioned in the duct such that ambient air entering the air intake opening contacts at least one radiator, and the duct configured to include an exhaust opening positioned downstream of the at least one heat exchanger and the at least one radiator, such that ambient air flows in the air intake opening, through the duct to contact the heat exchanger and the radiator, and exits the duct through the exhaust opening.
