摘要： A centrifugal blower includes a housing, an impeller, and a guiding cover. The housing includes a compartment delimited by an annular wall. A radial air inlet is defined in the annular wall and communicated with the compartment. The compartment includes an axial opening. The impeller is rotatably mounted in the compartment and includes a hub and a plurality of blades. The guiding cover is mounted on top edges of the blades and includes an axial air inlet in a central portion thereof. The guiding cover covers the axial opening of the compartment without in contact with the housing. The blades and the guiding cover turn synchronously when the impeller turns. Airflow is driven by the blades and guided by the guiding cover and exits the housing via the radial air outlet.

摘要： An impeller for a radial-flow heat dissipating fan includes a hub and a plurality of blades surrounding the hub. The blades are connected to a circumference of the hub to allow joint rotation of the hub and the blades. More than one blade include an air inlet side edge and an air outlet side edge. The air inlet side edge of each of the more than one blade has a radial length smaller than that of the air out side edge, thereby increasing an air inlet amount and smoothly changing incoming axial airflow into centrifugal airflow.

摘要： An impeller for a radial-flow heat dissipating fan includes a hub and a plurality of blades surrounding the hub. The blades are connected to a circumference of the hub to allow joint rotation of the hub and the blades. The impeller includes an air inlet side and a bottom side. Distribution of the blades at the air inlet side of the impeller is sparser than that at the bottom side of the impeller, thereby increasing an air inlet amount.

摘要： A centrifugal blower includes a housing, a cover, and an impeller. The housing includes a peripheral wall delimiting an inner space. The peripheral wall further includes a first sidewall and a second sidewall respectively at two ends thereof. A radial air outlet is defined between the first sidewall and the second sidewall of the peripheral wall. A cover includes an axial air inlet communicated with the inner space of the housing. An impeller is rotatably mounted in the inner space of the housing and aligned with the axial air inlet. At least one auxiliary radial air inlet is defined in the peripheral wall and adjacent to one of the first sidewall and the second sidewall. When the impeller turns, an axial airflow is sucked into the inner space via the axial air inlet and an auxiliary radial airflow is sucked into the inner space via the auxiliary radial air inlet.

摘要： A fan housing with a noise-reducing structure includes a housing having a side wall. An air inlet is defined in the housing and an air outlet defined in the side wall of the housing. A plurality of supporting ribs are disposed in the air inlet and connected between inner and outer peripheries of the air inlet for supporting a motor base. At least one of the supporting ribs is adjacent to the air outlet and extends in a direction coincident to or intersects with a longitudinal line of the air outlet extending through a rotational axis of the motor base.
