Abstract: An electric fan system has a first electric blower 10, which utilizes a brushless motor, and a second electric blower, which utilizes a brushed motor, for distributing the cooling air to the radiator and the condenser. The system has an electronic engine control unit which activates only the first electric blower when it determines that the cooling water temperature is less than T2, and activates both the first and second electric blowers when it determines that the cooling water temperature is T2 or higher. The water temperature is based on a detection output from a cooling water temperature sensor. Thus, since the electric blower is not activated unless the cooling water temperature becomes T2 or higher, use of the brushed motor is limited and its life is increased.

Abstract translation: 电风扇系统具有使用无刷电动机的第一电动鼓风机10和利用有刷电动机的第二电动鼓风机，用于将冷却空气分配到散热器和冷凝器。 该系统具有电子发动机控制单元，当确定冷却水温度小于T 2时仅激活第一电动鼓风机，并且当确定冷却水温度为T 2时激活第一和第二电动鼓风机， 更高。 水温基于冷却水温度传感器的检测输出。 因此，除非冷却水温度变为T 2以上，否则电动鼓风机不起动，所以使用有刷电动机是有限的，其寿命增加。
