Abstract (en)
[origin: US2008089025A1] A fan arrangement has an electric motor ( 18 ) that serves to drive a fan wheel ( 26; 170 ) and that has an internal stator ( 44 ) and an external rotor ( 22 ), with which latter the fan wheel is drivingly connected. Arranged on a circuit board ( 17 ) are components ( 11 ) that are coolable, at least in part, by an air flow ( 13 ) generated during operation by that fan wheel ( 26; 170 ). Associated with the fan wheel is an air-directing element ( 100 ) that is mounted on the circuit board ( 17 ) separately from the electric motor ( 18 ) so that, in operation, a cooling air flow ( 13 ) is generated which emerges from the fan arrangement ( 16 ) between the circuit board ( 17 ) and air-directing element ( 100 ).
