Abstract
A cooling system includes a fan group with a number of fans arranged in a row, a rail extending in a direction parallel to the row of the fans. A backup fan slidably mounted to the rail, a motor configured to control the movement of the backup fan, and a control board to determine whether there exists one malfunction fan in the fan group. When one abnormal fan exists in the fan group, the control board outputs a control signal to the motor, to enable the motor to drive the backup fan to move to a location corresponding to the abnormal fan.
Claims10
A cooling system, comprising:
- a fan group comprising a plurality of fans arranged in a row;
- a rail extending in a direction parallel to the row of the fans;
- a backup fan slidably mounted to the rail;
- a motor configured to control the movement of the backup fan;
- and
- a control board to determine whether there exists at least one malfunction fan in the fan group;
- wherein when at least on fan in the fan group is abnormal, the control board outputs a control signal to the motor, to enable the motor to drive the backup fan to move to a location corresponding to the abnormal fan.
A control method for a plurality of fans in a fan group and a backup fan, wherein the backup fan is slidably mounted to a rail by a motor, the control method comprising:
- obtaining status information and a number of each fan in the fan group;
- determining whether there exists at least one malfunction fan in the fan group according to the status information;
- outputting a determining signal in response to the existence of at least one abnormal fan;
- obtaining a location corresponding to the abnormal fan according to the determining signal;
- outputting a control signal to the motor to drive the backup fan to move to the location of the abnormal fan;
- and
- outputting a startup signal to a baseboard management system (BMC), to control the backup fan to operate.
