Abstract
Abstract A cooling-air ducting system in the front-end space of a motor vehicle is described, which front-end space is delimited by a front-end wall having an air inlet opening and in which front-end space is arranged a cooler through which cooling air flows, having a cooling-air ducting space between front-end wall and cooler and a cooling-air fan downstream of the cooler. In order to achieve a sufficient cooler surface area, in particular in the case of a low overall height of the front-end space, while continuing to use the cooling air fan driven by the internal combustion engine, the cooler is divided into a plurality of individual component parts which are arranged staggered relative to one another in such a way that they overlap with spacing relative to one another in the driving direction of the motor vehicle and that they are acted upon in common by the cooling-air fan.
