Abstract
A cooler device for a motor vehicle includes a charge air cooler with a first cooler element, an EGR cooler with a second cooler element, the first and second cooler elements are arranged beside and substantially in plane with one another. The cooler elements each comprise pipelines for the respective medium to be cooled. Air passages for a cooling air flow are arranged between the pipelines. A screening device is arranged in front of or behind the cooler elements to regulate the air flow through elements. A control mechanism switches the screening device to and from between an open position in which the screening device does not, or at least does not appreciably, limit air flow through the air passages of the cooler elements, and a closed position in which the screening device limits the air flow through the air passages between all of the pipelines of the second cooler element and the air flow through the air passages between only some of said pipelines of the first cooler.
