  • the fan 4 conveys the air essentially vertically upwards and acts on the heat exchanger 6 arranged above it, which is coupled via lines 7 to the coolant circuit of the vehicle. After flowing through the heat exchanger 6, the air is deflected via the air deflecting device 8 in such a way that it can be discharged essentially in the opposite direction to the direction of travel via the air dispensing device 10.
