Abstract
An impeller for a centrifugal blower includes at least one blade oriented in a radial direction of the impeller. The blade has an airfoil section with a radially inward end and a radially outward end that are thinner than at least one point between the radially inward end and the radially outward end.
Claims20
An impeller for a centrifugal blower, the impeller comprising:
- at least one blade oriented in a radial direction of the impeller, the blade including an airfoil section with a radially inward end and a radially outward end that are thinner than at least one point between the radially inward end and the radially outward end.
An impeller for a centrifugal blower, the impeller comprising:
- a hub configured to connect to an axle at a rotational axis;
- and
- at least one blade connected to the hub and oriented in a radial direction of the impeller relative to the rotational axis, the blade including:
- an airfoil section with a radially inward end and a radially outward end that are thinner than at least one point between the radially inward end and the radially outward end, the airfoil section having a negative rake relative to a direction of rotation of the impeller, and
- an exit section with a more positive rake than the airfoil section.
2 more elements
A centrifugal blower for use in an electronic device, the centrifugal blower comprising:
- an impeller configured to rotate around a rotational axis in a rotational direction;
- and
- a housing including at least one volute, the volute including:
- an outer wall positioned at a volute radius that increases in the rotational direction of the impeller.
