ABSTRACT:
A fresh air supply device is disclosed which is connected upstream of a blower of a heating or air conditioning unit in a motor vehicle. The blower is accommodated by a housing with the fresh air entering into a gap between the windscreen and the adjacent hood. The fresh air is deflected while water and foreign bodies are separated and is supplied to a filter underneath the hood. The filter can be exchanged by pulling it out upwards. Downstream of the filter, the air enters the intake side of the blower. In order to prevent unintentional heating up of the fresh air in the intake tract, while retaining easy exchangeability of the filter, the filter is covered by an intake scoop which can be moved away and is thermally shielded relative to the vehicle hood or bonnet.
