Abstract
A fan control system includes a fan, a dust barrier near the fan, a fan actuator to rotate the fan in a normal direction and a reverse direction, a fan controller configured or programmed to control a manner in which the fan actuator is driven, a clogging degree calculator configured or programmed to calculate a clogging degree of the dust barrier based on drive behavior of the fan, and a reverse rotation instructor configured or programmed to instruct the fan controller based on the clogging degree to rotate the fan in the reverse direction.
Claims11
A fan control system, comprising:
- a fan;
- a dust barrier at or adjacent to the fan;
- a fan actuator to rotate the fan in a normal direction and a reverse direction;
- a fan controller configured or programmed to control a manner in which the fan actuator is driven;
- a clogging degree calculator configured or programmed to calculate a clogging degree of the dust barrier based on drive behavior of the fan;
- and
- a reverse rotation instructor configured or programmed to instruct the fan controller based on the clogging degree to rotate the fan in the reverse direction.

A work machine, comprising:
- a cooling fan to cool a heat generating component with use of a cooling medium;
- a dust barrier at or adjacent to the cooling fan;
- a fan actuator to rotate the cooling fan in a normal direction and a reverse direction;
- a fan controller configured or programmed to control a manner in which the fan actuator is driven;
- an internal temperature detector to detect a temperature of the cooling medium or a temperature of the heat generating component;
- a clogging degree calculator configured or programmed to calculate a clogging degree of the dust barrier based on the temperature detected by the internal temperature detector and drive behavior of the cooling fan;
- and
- a reverse rotation instructor configured or programmed to instruct the fan controller based on the clogging degree to rotate the cooling fan in the reverse direction.
