Abstract
A cover plate for a cooling fan motor includes a heat shield portion spaced from the motor and a deflector portion extending beyond the motor. The deflector portion redirects axial discharge airflow across the motor to provide cooling, thereby improving the life of the motor bearings and the operating efficiency of the motor.
Claims20
An assembly for cooling a vehicular engine compartment, comprising:
- (a) a fan;
- (b) a motor for rotating the fan;
- (c) bracket means downstream of the fan for mounting the motor;
