Abstract
Systems and methods for cooling a server case are disclosed. In at least one embodiment, a fan switches between an axial operation mode and a centrifugal operation mode to change a direction of an air flow within this server case.
Claims20
A method, comprising:
- causing a fan to switch between an axial operation mode and a centrifugal operation mode by adjusting a respective blade angle of each blade of a plurality of blades based at least in part upon one or more acoustic values.
A system, comprising:
- a fan comprising a plurality of blades, the blades rotatable about an axis of the fan, each blade of the plurality of blades arranged at a respective blade angle, a blade pitch control assembly to drive rotation of each blade of the plurality of blades about a corresponding pivot axis to adjust the respective blade angle of each blade;
- and
- at least one processor to:
- cause the fan to operate in an axial operation mode to direct air parallel to the axis of the fan;
- determine at least one temperature value exceeds a threshold;
- and
- cause the fan to operate in a centrifugal operation mode to direct air perpendicular to the axis of the fan.
4 more elements
A system, comprising:
- a case;
- and
- a fan comprising a plurality of blades, the blades rotatable about an axis of the fan, each blade of the plurality of blades arranged at a respective blade angle, the fan positioned within the case to direct an air flow into the case, the respective blade angle of each blade being adjustable to change an operational mode of the fan from an axial operation to a centrifugal operation mode, a blade pitch control assembly to drive rotation of each blade of the plurality of blades about a corresponding pivot axis to adjust the respective blade angle of each blade.
