Abstract
A cooler device for a motor vehicle including a charge air cooler with a first cooler element, an EGR cooler with a second cooler element arranged substantially in plane with the first cooler element is disclosed. A screening device regulates air flow through the cooler elements. A control mechanism is operable to switch the screening device to and from between an open position and a closed position. A first screening portion allows more air to pass through than a second screening portion when the screening device is in the closed position such that air flow through the first cooler element is limited to a lesser extent than through the second cooler element in the closed position.
Claims12
A cooler device for a motor vehicle, the cooler device comprising:
- a charge air cooler having a first cooler element for cooling of charge air for a combustion engine of the motor vehicle and an EGR cooler having a second cooler element for cooling of exhaust gases which are to be led back to the combustion engine, the first cooler element and the second cooler element are arranged substantially in plane with one another;
- a screening device arranged in front of or behind the cooler elements, the device is operable to regulate air flow through the cooler elements, the screening device comprises a first screening portion associated with the first cooler element and a second screening portion associated with the second cooler element;
- and
- a control mechanism operable to switch the screening device to and from between an open position in which the screening portions do not, or at least do not appreciably, limit the air flow through the cooler elements, and a closed position in which the screening portions limit the air flow through the cooler elements;
- the first screening portion is configured to allow more air to pass through than the second screening portion allows to pass through when the screening device is in the closed position, in order thereby to regulate the air flow through the cooler elements in such a way that the air flow through the first cooler element is limited to a lesser extent than the air flow through the second cooler element when the screening device is in the closed position.
