The ventilator (1) has a curved surface container (2) with an input and an output channel. A central motor (5) drives the turbine (4) circulating air through the channel and an outer orifice (7). A secondary narrow channel (3) sucks in air onto an inlet static outer section (8). The outer section holds high power electronic components (10), such as transistors or resistances of the electric motor control circuit. Thus the passing air cools the electronic components. |
