Abstract: A vehicle cooling system includes a heat exchanger, upper and lower coolant hoses extending between the heat exchanger and a vehicle power system for carrying liquid coolant to and from the vehicle power system, and an expansion tank fluidly coupled to the lower coolant hose. The vehicle cooling system further includes an active coolant monitoring system that includes a coolant leak sensor that detects leakage of the liquid coolant from the vehicle cooling system and a coolant contamination sensor that detects contamination of the of liquid coolant. The vehicle cooling system further includes an electronically controllable coolant flow shutoff valve in series with the lower coolant hose adjacent a lower coolant outlet of the heat exchanger. The electronically controllable coolant flow shutoff valve is closed when the coolant pump is off and open when the coolant pump is on.

Abstract: Wind shielding system and method for a radiator cooling package of a vehicle are disclosed. The wind shielding system has a wind shielding screen, a temperature sensor for detecting an air temperature of an ambient air surrounding the radiator cooling package and an actuator for moving the wind shielding screen to a closed configuration with respect to the radiator cooling package by an electronic control unit based on the detected air temperature. The wind shielding screen in the closed configuration impedes formation of ice on the radiator cooling package from an airflow at the detected air temperature by covering the radiator cooling package. A vehicle having the wind shielding system to perform the wind shielding method is also provided. A computer program product that when executed by the wind shielding system causes the wind shielding system to perform the wind shielding method is also provided.

Abstract: The invention relates to a cooling system for a vehicle, the cooling system comprising a cooling fan comprising a ram air turbine disposed in an aperture of a fan shroud, the fan shroud comprising: an opening, a shutter mechanism movable between a closed position in which it closes the opening, and an open position in which it opens the opening so that a ram air flow can pass through the opening, wherein the fan shroud further comprises: a velocity sensor configured to measure ram air flow velocity, a temperature sensor configured to measure ram air flow temperature, and an actuator configured to move the shutter mechanism between the closed position and the open position based on measured ram air flow velocity and measured ram air flow temperature.
