摘要： Disclosed is a cooling fan for a microwave oven, adapted for directing axially sucked airflow to be evenly distributed over a magnetron and a high voltage transformer. The cooling fan comprises a mixed flow fan having a specified hub angle, or an axial flow fan having optimized design parameters such as a ratio of an outer diameter of the fan to a width of a electric device chamber defined in a cabinet, a hub ratio, a sweep angle, a pitch angle, a maximum camber rate, etc.
