Abstract
A cooling fan having a fan housing, a motor which is positioned within the fan housing and a plurality of electronics components which are associated with the motor includes at least one strut which extends radially between the motor and the fan housing and on which the electronics components are mounted.
Claims36
A cooling fan which comprises:
- a fan housing which includes a central axis;
- a motor which is positioned within the fan housing;
- an impeller which is rotated by the motor to generate an air stream through the fan housing;
- a plurality of power electronics components which are associated with the motor;
- and
- at least one generally planar strut which is oriented generally parallel to the central axis, the strut comprising a central edge portion which is secured to the motor and first and second radially opposite end portions which are secured to the fan housing or to a diffuser tube which is connected to a downstream end of the fan housing;
- wherein at least some of the power electronics components are mounted on the strut in the path of the air stream.
