Abstract

A device for regulating an air flow for engine cooling, is disclosed herein with a fan element arranged over part of a heat exchanger face which can be traversed by air, and a covering element over a further part of the exchanger face, the covering element extending from the fan element up to an end of the exchanger face, and able to be at least partially selectively opened to allow air to flow through. A device providing an improved efficiency of the heat exchanger in at least one operating state of a motor vehicle is provided that is possible for a first opening section, which, in order to avoid excessive recirculation, is at a minimum distance from the fan element, the covering element is selectively opened and it is possible for at least one second opening section which substantially adjoins the fan element to be selectively opened.
