Abstract: A baffle assembly includes a screen defining at least one air flow passage through the screen, a shut-off device having at least one flap configured to move between at least two positions to control circulation of the air flow through the passage, a lever controlling the positions of the flap, and at least one lighting device borne by the lever and distinct from the flap.

Abstract: A method for operating a refrigeration system for a vehicle with a refrigerant circuit including a heat exchanger. A controllable environmental air flow (L) is flowed through the heat exchanger and the heat exchanger can be operated as a refrigerant condenser or a gas cooler for a refrigeration system operation.

Abstract: A method for controlling an active air flap of a vehicle is provided. The method includes receiving individual amounts of cooling demand required by a plurality of apparatuses requiring cooling that are installed within an engine room. Demand duties are then calculated based on the amounts of cooling demand required by the respective apparatuses and correction duties for the respective apparatuses are calculated by multiplying the demand duties for the respective apparatuses by an outside temperature factor according to the outside temperature of the vehicle. A maximum value out of the correction duties for the respective apparatuses is selected as a final duty and the active air flap is operated with an opening degree based on the selected final duty.

Abstract: A fluid management system for a cooling module of a vehicle air conditioning system. The cooling module includes a first heat exchanger in fluid communication with a liquid cooling system of the vehicle and a second heat exchanger disposed upstream of the first heat exchanger and in fluid communication with the vehicle air conditioning system, wherein the fluid management system minimizes an inlet fluid temperature of the second heat exchanger of the cooling module.

Abstract: A cooling system includes: a shutter grille provided to an air guide port configured to guide air to a power compartment in which a power source of a vehicle is installed; a radiator configured to radiate heat from coolant for cooling the power source; a radiator fan configured to send the air to the radiator and the power source; a shutter grille controller configured to control opening and closing of the shutter grille; and a radiator fan controller configured to control the radiator fan. If a power source load on the power source is less than predetermined power source load, and if an air conditioning load on an air conditioner is equal to or greater than predetermined air conditioning load, the shutter grille controller and the radiator fan controller operate the radiator fan with the shutter grille closed.

Abstract: A baffle for disposition in a sump having a fluid containing cavity is disclosed. A first portion of the baffle has an outside edge abutting a side wall of the sump and an inner edge defining an opening. A second portion of the baffle extends downwardly from the inner edge to a lower edge abutting a bottom wall of the sump. At least one jalousie divider is disposed along the second portion of the baffle to regulate fluid flow through the baffle based on fluid temperature. A controller is coupled to the jalousie divider to selectively drive the jalousie divider to a closed position that prevents fluid flow through the baffle when the fluid temperature is below a temperature threshold and an open position that permits fluid flow through the second portion of the baffle when the fluid temperature is above the temperature threshold.

Abstract: An active grille comprises a plurality of blades and an active material in operative communication with the blades. The active material is in operative communication with the blades and is operative to change at least one attribute in response to an activation signal, wherein fluid flow through the grille changes with the change in the at least one attribute of the active material. By way of example, in vehicle applications, the blades of a grille disposed in front of an engine compartment can be selectively positioned to provide increased airflow through the radiator due to increases in engine coolant temperature. As such, the active grille can be configured to improve vehicle fuel economy while maintaining proper engine cooling. An activation device, controller and sensors may be employed to further control the change in at least one feature of the active grille.

Abstract: Fan horsepower requirements and the size of power train heat exchangers may be reduced in a vehicular cooling system that includes an inlet (14) for the receipt of ambient air and first and second heat exchangers (28), (40) in proximity to the inlet (14) to receive ambient air therefrom and which are respectively adapted to receive first and second heat exchanger fluids by the ambient air. The first and second heat exchangers (28), (40) are in side by side, substantially non superimposed relation to define first and second air flow paths (52, 54) extending in fluid flow parallel to a respective one of the heat exchangers (28), (40) from the inlet (14) to points (50), (52), (54) of discharge. A fan (44) flows air from the inlet (14) through the flow paths (52, 54) and a shutter (56) is located in one of the flow paths (54) and is movable between first and second positions respectively restricting air flow and allowing relatively unrestricted air flow.
