Cooler arrangement for a motor vehicle

A cooler device for a motor vehicle comprising

• a radiator liquid cooler with a first cooler element operable for cooling of radiator liquid for a combustion engine of the motor vehicle;
• a charge air cooler with a second cooler element operable for cooling of charge air for the combustion engine;
• the radiator liquid cooler and the charge air cooler being assembled to one another, side by side, and with a narrow space between the cooler elements,
• a screening device arranged in the narrow space between the cooler elements and operable to regulate an air flow past the screening device and through the cooler elements downstream in the direction of air flow through the cooler device;
• and
• a control mechanism to switch the screening device to and fro between an open position in which the screening device does not, or at least does not appreciably, limit the air flow through the cooler elements, and a closed position in which the screening device limits the air flow between the cooler elements,
• wherein the screening device comprises two screening elements having planar disc-shaped faces which face one another and the screening elements have apertures through them, at least one of the screening elements being movable in a respective plane of extent relative to the other screening element under operation by the control mechanism, the apertures in the screening elements being arranged to cooperate in order to form air passages which extend through the screening device and such that the passages are larger when the screening device is in the open position than when the screening device is in the closed position, the planar disc-shaped faces covering an entire surface area of each of the two screening elements, the surface area being an area of a surface of each of the two screening elements transverse to the direction of air flow through the cooler device.
