Abstract
A cooler device in a vehicle comprises a first cooler element in which compressed air is cooled by ambient air and a second cooler element in which recirculating exhaust gases are cooled by ambient air. The cooled recirculating exhaust gases and the cooled compressed air are mixed before they are led to a supercharged combustion engine of the vehicle. The cooler device comprises a common tubular outlet element for the first cooler element and the second cooler element so that said cooler elements constitute a composite unit.
